With reference to
In the embodiment, the aerosol generating substrate 30 internally has the porous and loose structure. In a drying process of manufacturing of the aerosol generating substrate 30, a swelling agent in a raw material is heated to generate gas, such that the aerosol generating substrate 30 puffs, and before drying, water in the aerosol generating substrate 30 containing a lot of water is generated through heating and evaporation. In the embodiment, the gaps of the porous and loose structure formed through a swelling technology are not uniformly and irregularly distributed in the space. Compared with a sheet type and a granule type in the prior art, the embodiment achieves a smaller void ratio. Although internal gaps may allow heated aerosol to pass through, no through hole is provided from one end to the other end of the aerosol generating substrate 30. Therefore, when the aerosol generating substrate 30 in the embodiment is unheated, a suction resistance is greater than that of an existing heat-not-burn cigarette.
With reference to
In the embodiment, the aerosol generating substrate 30 may have a porous and loose structure in which crystal blocks adhere to each other and integrated, with small internal gaps, which achieves a desirable heat conduction effect and uniform heating. Compared with gaps in sheet-type and granule-type aerosol generating substrates in the prior art are larger, which cause a worse heat conduction effect, the aerosol generating substrate 30 of the present disclosure internally has a porous and loose structure, with smaller pores, such that a desirable heat conduction effect and even heating may be achieved.
In the embodiment, the aerosol generating substrate 30 includes an aerosol generating agent. When the aerosol generating substrate is heated, the aerosol generating agent generates aerosol. When the aerosol generating substrate 30 is heated with a heating part of a heating apparatus, the aerosol generating agent in the aerosol generating substrate 30 reaches a boiling point and is evaporated into the aerosol, which is sucked by a smoker.
A manufacturing method for the aerosol generating substrate 30 according to the present disclosure will be disclosed below. The manufacturing method of the present disclosure is implemented from the aspects of raw material composition, and molding and drying processes of the aerosol generating substrate 30.
In the aspect of raw material composition, raw material components for manufacturing the aerosol generating substrate 30 include a swelling agent, a large amount of water, and a plant raw material. The swelling agent in the raw material is heated in a drying process so as to generate gas (carbon dioxide, CO2), and the gas formed in the substrate causes the raw material to puff. When the gas is released, the aerosol generating substrate 30 internally has a porous and loose structure. In addition, a large amount of water included in the aerosol generating substrate 30 evaporates in the drying process, such that the aerosol generating substrate 30 internally has a porous and loose structure.
In the molding process of the aerosol generating substrate 30 of the present disclosure, the plant raw material is crushed, then various flavor and fragrance, tobacco extract, an aerosol generating agent, an aerosol substrate forming agent, an aerosol substrate swelling agent, an aerosol sustained-release agent and water are mixed with the crushed plant raw material, and a paste-like material is manufactured, such that the aerosol generating substrate 30 before drying is molded through the molding process. Various plant raw materials are regarded as a main carrier of the aerosol generating substrate 30. Various flavor and fragrance and tobacco extract may provide different flavors for the aerosol generated. The aerosol generating agent generates the aerosol when the aerosol generating substrate 30 is heated. The aerosol substrate forming agent may mold the paste-like material into a required shape of the aerosol generating substrate 30 and permeate the paste-like material into the crystal blocks and the fiber filaments. The swelling agent may generate gas when the aerosol generating substrate 30 is heated in the drying process, such that the paste-like material internally has a porous structure, and further the aerosol generating substrate 30 having a porous structure may allow the aerosol to pass through. A large amount of water is added to a raw material formula of the aerosol generating substrate 30, a weight ratio of water to all raw materials may reach 30%-60%, and a large amount of water is removed through drying, such that the aerosol generating substrate 30 forms a porous and loose structure. In the embodiment of the drying process of the present disclosure, drying processes used include a microwave swelling drying process, a vacuum drying baking process, a vacuum freeze-drying process, and a high-frequency induction drying process, such that the aerosol generating substrate 30 may puff to form a porous and loose structure in the drying process.
According to the above contents disclosed, in a manufacturing embodiment of the aerosol generating substrate 30 of the present disclosure, firstly, the plant raw material of the aerosol generating substrate 30 is pretreated, and the plant raw material is pretreated mainly through natural fermentation or fermenting-enzyme fermentation of the plant raw material, such that miscellaneous odor in the plant raw material is reduced, and remaining taste is improved. Then, various raw materials for manufacturing the aerosol generating substrate 30 are made into the paste-like material, so as to prepare for subsequent molding of the aerosol generating substrate 30. Further, the paste-like material is made into a rod-shaped aerosol generating substrate 30 through a jig. Finally, the paste-like aerosol generating substrate 30 is dried and puffs through the drying process, such that a large amount of water in the aerosol generating substrate 30 is evaporated, and a loose aerosol generating substrate 30 may be obtained.
In the drying process, drying parameters have to be controlled, such that the aerosol generating substrate 30 has proper hardness and porosity. The drying temperature does not have to be too high. Too high a drying temperature may cause excessively high hardness of the aerosol generating substrate 30, such that it is difficult to insert the aerosol generating substrate 30 into a heating apparatus for suction, and meanwhile, a large amount of tobacco extract and various flavor and fragrance in the aerosol generating substrate 30 may be volatilized, and taste may deteriorate. It can be ensured that the aerosol generating substrate 30 has a certain porosity only by selecting a proper drying process, such that the aerosol may smoothly pass through an interior of the aerosol generating substrate 30 in a heating and suction process.
The raw material composition of the aerosol generating substrate 30 of the present disclosure will be disclosed below.
The raw materials of the aerosol generating substrate 30 include a plant raw material, tobacco extract, flavor and fragrance, an aerosol generating agent, an aerosol substrate forming agent, an aerosol substrate swelling agent, an aerosol sustained-release agent, and water.

The tobacco extract may be one or more combinations of Zimbabwe tobacco extract, burley tobacco extract, Greek tobacco extract, Yunyan tobacco extract, American tobacco extract, Virginia tobacco extract, sun-cured red tobacco extract, tamarind extract, oriental tobacco extract, nicotine, and nicotine salt.

The water is drinking water that satisfies a hygienic standard.
In other embodiments, when a component of a heating apparatus without a heating sheet is matched, a metal material or a magnetic material may be added to the raw material composition of the aerosol generating substrate 30, and the aerosol generating substrate may be dried through a high-frequency reaction principle in the drying process. If the aerosol generating substrate 30 of the embodiment is internally provided with a metal material or a magnetic material, the aerosol generating substrate 30 may be heated through a hall effect when the aerosol generating substrate 30 is inserted into the heating apparatus without the heating sheet for heating, so as to be sucked by a smoker.
In some embodiments, the metal material may be, but is not limited to, at least one of metal elements such as iron, copper, aluminum, chromium, magnesium, zinc, titanium, cobalt, and nickel. The shape of the metal material may be granular, sheet-shaped, strip-shaped, rod-shaped, etc.
In some embodiments, the magnetic material may be, is not limited to, at least one of magnetic materials such as iron, cobalt, nickel and alloys thereof, an aluminum-nickel (cobalt) alloy, an iron-chromium (cobalt) alloy, an iron-chromium (cobalt) alloy, and iron-chromium-molybdenum and iron-aluminum-carbon alloys. The shape of the magnetic material may be granular, sheet-shaped, strip-shaped, rod-shaped, etc.
The plant raw material in the embodiment is rich in starch, protein, organic acid, aromatic substances, etc. when being picked, internal quality of which has some defects in different degrees, such as heavy green miscellaneous odor and strong irritation. Molecular structures of various plant raw materials untreated are relatively large. Smell of a macromolecular structure is relatively strong, such that the flavor and fragrance can hardly cover smell of macromolecules. For instance, a protein content in tea leaves is 21%-28%, which may produce pungent feeling, enhanced irritation, increased bitterness and unpleasing protein odor in the heating process.
Therefore, before the paste-like material is manufactured, a first step needs to be conducted to pretreat various plant raw materials of the aerosol generating substrate 30, so as to reduce various miscellaneous odor of the plant raw materials.
The plant raw material may be pretreated through natural fermentation and fermenting-enzyme fermentation of the plant raw material.
In the embodiment, the plant raw material of the aerosol generating substrate 30 is pretreated through natural fermentation.
The natural fermentation of the plant raw material is conducted by storing at least one of herbal plants, Chinese herbal plants or tobacco raw materials in a warehouse having a certain temperature and humidity for a certain time for natural alcoholization, where an optional temperature is 18° C.-25° C., a relative humidity is 60%-65%, and storage time is 1 year-3 years. The natural alcoholization of the plant raw material can promote conversion of chemical components in the plant raw material, such that the miscellaneous odor of the plant raw material is reduced, irritation is reduced, and remaining taste is improved. Further, smoke generated by the aerosol generating substrate 30 may be more mellow and delicate in the heating process.
However, a natural fermentation method for the plant raw material is used for alcoholization, which takes a long period and occupies a large warehouse area. In order to shorten alcoholization time of the plant raw material, the alcoholization time can be greatly reduced through biotechnology and fermenting-enzyme fermentation.
Many studies show that some protein in the raw material may be hydrolyzed into a series of micromolecular nitrogen-containing compounds through individual or comprehensive effects of various enzymes. The transformants may have a Maillard reaction with reducing sugar, alcohol, etc. so as to generate edible or tobacco fragrance. The products have strong aroma of nuts, sauce, roasted, caramel, fruit, tobacco, and Chinese herbal medicines, which can effectively enrich aroma of cigarettes and enhance smoking feeling, so as to reduce scorched smell and miscellaneous gas in the raw material, make aroma permeability better, coordinate smell of smoke, reduce the scorched smell, and make a proportion of internal chemical components of cigarettes more harmonious. In addition, short peptides and amino acids may also react with phenolic compounds, pigment degradation products and lipid molecules, products of which can further improve smoking quality of cigarettes.
In other embodiments, the plant raw material of the aerosol generating substrate 30 is pretreated through fermenting-enzyme fermentation.
A fermenting-enzyme fermentation method for the plant raw material is as follows: fermenting enzymes and the plant raw material are mixed for fermentation in a certain temperature, humidity and pH environment. An addition ratio of fermenting enzymes is 0.001%-1%. A fermentation temperature is 30° C.-65° C., and preferably 40° C.-50° C. A pH value of fermentation is 5.5-10, and preferably 6.5-8.5. Fermentation time is 10 days-30 days. A type of the fermenting enzymes used may be at least one of protease, pectinase, cellulase, lipase, etc.
Protein and other substances in the plant raw material are degraded to other micromolecular substances after fermenting-enzyme fermentation. For instance, the protein may be degraded to generate short peptides, free amino acids, etc. Scorched smell and miscellaneous odor generated by macromolecular substances in the plant raw material in the heating process are reduced, and various chemical components in the plant raw material are coordinated, such that smell of the smoke can be improved, and further the smoking quality can be improved.
A second step was as follows: various raw materials of the aerosol generating substrate 30 were made into the paste-like material, so as to prepare for later molding of the aerosol generating substrate 30.
The present disclosure provides an embodiment of a manufacturing method for a paste-like material of the aerosol generating substrate 30. After the plant raw material was subjected to fermenting-enzyme fermentation, the paste-like material of the aerosol generating substrate 30 was made. The herbal plants, Chinese herbal plants, tobacco raw materials or wood fibers subjected to fermenting-enzyme fermentation were crushed a crusher, where a crushing granule size was 10 μm-500 μm. One or more combinations of crushed herbal plants, Chinese herbal plants, tobacco raw materials or wood fibers were taken in proportion, and uniformly mixed, such that the crushed and uniformly-mixed plant raw material was obtained. 40 parts-80 parts of crushed and uniformly-mixed plant raw materials, 10 parts-20 parts of tobacco extract, 30 parts-60 parts of aerosol generating agents, 10 parts-30 parts of flavor and fragrance, 1 part-5 parts of aerosol substrate forming agents, 1 part-3 parts of aerosol substrate swelling agents, 1 part-10 parts of aerosol sustained-release agents, and 30 parts-50 parts of water were taken, mixed and stirred together, and then uniformly stirred with a stirrer so as to form the paste-like material, which may also be referred to as paste.
In the embodiment, when herbal plants, Chinese herbal plants, tobacco raw materials or wood fibers are crushed with a crusher, plant raw material powder obtained through crushing includes granular objects and fiber filaments. A granule size of the granular objects is 10 μm-500 μm, and an outer diameter of the fiber filaments is 5 μm-30 μm. The granular objects are in irregular shapes.
In the embodiment, in the prepared paste, the aerosol generating agent (for instance, glycerinum), the flavor and fragrance and water permeate into the above granular objects and fiber filaments.
In the embodiment, the paste made from various raw materials of the aerosol generating substrate 30 may also be referred to as slurry, fluid slurry, mixture, wet substances, gel, colloid, and mash, and certainly may be replaced with other terms, so as to achieve the same efficacy or function of the paste of the present disclosure, without departing from the scope of the paste of the present disclosure.
It may be seen from the above embodiment that an addition ratio of water to the aerosol generating substrate 30 of the present disclosure is relatively large, and the made paste-like material has moderate humidity and hardness, where the water is not very little. The large water addition ratio has a main function of facilitating formation of the paste-like material from various raw materials, so as to facilitate a filling operation in a next step, such that the paste-like material may be extruded and molded with an extruder. Meanwhile, after a large amount of water in the raw material is evaporated in the drying process, micropores are formed in the aerosol generating substrate 30, such that the aerosol generated by heating the aerosol generating substrate 30 with the heating apparatus may smoothly pass through the micropores, and a moderate suction resistance may be achieved. If a moisture content of the prepared paste-like material is excessively low, extrusion difficulty of an extrusion device may be increased, and a density of the aerosol generating substrate 30 may be increased, which makes the aerosol pass through the paste-like material not easily. If a moisture content of the prepared paste-like material is excessively high, molding of the aerosol generating substrate 30 is not facilitated. Therefore, the moisture content of the prepared paste-like material accounts for 30%-60% of a weight of the paste-like material.
A third step was as follows: the paste-like material of the aerosol generating substrate 30 was subjected to filling and molding.
The aerosol generating substrate 30 of the present disclosure was extruded and molded with a strip extruder. An extrusion method was as follows: a driving device drove a feeding device to extrude and mold the paste-like material through a material outlet; and the paste-like material was cut off after being extruded into strips, or cut off after being wrapped in a sheet packaging material after being extruded, or directly extruded into a tubular packaging material, such that the undried aerosol generating substrate 30 was obtained.
The substrate extruded from the strip extruder may have a longitudinal cross section of a circular, triangular, quadrilateral, polygonal or irregular shape.
The driving device of the strip extruder may use electric driving, hydraulic driving, pneumatic driving, or other driving methods. The feeding device may be a piston device, a screw device, a push rod device, etc.

After all the embodiments of the aerosol generating substrate molding devices 800-814 in
With reference to
In the embodiment, the aerogel generating device includes a container 203, a pump 205, a pipe 207, and a pipe 209. The container 203 is configured to accommodate a solution. The pump 205 is configured to suck the solution in the container 203 through the pipe 207, and convey the solution to the material outlet 208 of the aerosol generating substrate molding device 800 through the pipe 209.
In the embodiment, a first solution and a second solution are mixed in the container 203. The first solution is a biopolysaccharide or polyamino acid solution containing carboxylate groups. The second solution is a divalent/trivalent metal ion solution. After the first solution and the second solution are mixed, gel is formed through ionic crosslinking through coordination between metal ions and carboxylate groups. The gel formed has a sealed packaging effect.
In other embodiments, the first solution may also be added when the paste-like material is made, such that the paste-like material containing the first solution may be made. In a process of making the paste-like material, the first solution added contains moisture, so the added moisture may be reduced appropriately when the paste-like material is made. In this way, the made paste-like material is prevented from being too thin and difficult to mold. When the paste-like aerosol generating substrate containing the first solution is extruded from the aerosol generating substrate molding device 800, the second solution in the container 203 is injected through the pump 205 from the material outlet 208 of the aerosol generating substrate molding device 800, and the second solution reacts with the first solution in the extruded paste-like aerosol generating substrate, such that a gel-like paste-like aerosol generating substrate is generated.
Because the gel has an encapsulation effect, gel substances in the aerosol generating substrate may lock the aerosol generating agent and the flavor and fragrance in the aerosol generating substrate at room temperature, such that the flavor and fragrance is not volatile. Meanwhile, because the aerosol generating agent has water absorption, the gel substances can also prevent the aerosol generating substrate from becoming damp due to moisture absorption in air.
When the aerosol generating substrate is heated, the aerosol generating agent in the aerosol generating substrate is vaporized to form the aerosol, and meanwhile, the flavor and fragrance is mixed with the aerosol generating agent when the paste is made, such that the flavor and fragrance is are also taken out when the aerosol generating agent is vaporized to form the aerosol.
In the embodiment, a first solvent of the gel is carboxylate ion enrichment, which may be sodium alginate, sodium hyaluronate, propylene glycol alginate, polyaspartic acid, polylysine, polyglutamic acid, etc. A concentration of the first solvent is 1%-30%. A second solvent is food-grade high valence metal ions, which may be a calcium chloride solution, a calcium lactate solution, a magnesium chloride solution, a zinc chloride solution, a ferrous chloride solution, a ferric chloride solution, etc. A concentration of the second solvent is 1%-30%.
In another embodiment, a first solvent of the gel is phenolic hydroxyl group enrichment, which may be tannic acid or geniposide. A concentration of the first solvent is 1%-40%. A second solvent of the gel is food-grade high valence metal ions, which may be a calcium chloride solution, a calcium lactate solution, a magnesium chloride solution, a zinc chloride solution, a ferrous chloride solution, a ferric chloride solution, etc. A concentration of the second solvent is 1%-30%.
In some embodiments, a first solvent of the gel is aldehyde-based material enrichment, such as oxidized sodium alginate, oxidized sodium hyaluronate, oxidized starch and its derivatives, oxidized guar gum and its derivatives, oxidized cellulose and its derivatives, oxidized xanthan gum and its derivatives, and oxidized konjac gum and its derivatives. A concentration of the first solvent is 2%-30%. A second solvent is amino material enrichment, which may be chitosan and its derivatives, polylysine, polyglutamic acid, polyaspartic acid, polyarginine, etc. A concentration of the second solvent is 1%-30%.
In some embodiments, a first solvent of the gel is dextrin-rich material, such as β-cyclodextrin, hydroxypropyl-β-cyclodextrin, and methyl-β-dextrin. A concentration of the first solvent is 5%-30%. A second solvent is adamantane enrichment, such as adamantane graft, with a concentration of 5%-30%.
Specifically, in the embodiment, the first solution and the second solution may be interchanged without influencing an effect of the aerosol generating substrate of the present disclosure. That is, when the paste-like material is made, the paste-like material containing the second solution is made by adding the second solution. The container 203 accommodates the first solution.
The undried aerosol generating substrate obtained in the above embodiment of the present disclosure has a high moisture content, and a porous and loose aerosol generating substrate 30 may be obtained after the subsequent drying step, so as to be suitable for insertion and heating of a heating apparatus.
The aerosol generating substrate 30 of the present disclosure is integral rod-shaped. The integral aerosol generating substrate 30 has advantages that a heat conduction effect is better when a heating part of the heating apparatus heats the substrate, and a better suction effect may be obtained.
A fourth step is as follows: the molded paste-like material substrate was dried and puffed through a drying process, such that a loose aerosol generating substrate 30 may be obtained.
The drying process is a key step in the manufacturing process of the aerosol generating substrate 30. The porous and loose structure of the aerosol generating substrate 30 is generated in the drying process.
As shown in
The drying device 820 for the aerosol generating substrate includes a box 406, a temperature sensor 404, and a heat source 402. The heat source 402 may use electric heating, air compressor heating, thermocouple heating, infrared heating, ultraviolet heating, magnetic induction heating, or other heating methods.
In the drying embodiment, at least one of the molded undried aerosol generating substrates 110, 112, 114, 116, 118, 120, 122, 124, 126, 128, 130, and 134 obtained in the previous step is put into the box 406. A temperature is set at 30° C.-80° C., which is preferably 45° C.-65° C. Drying time is 60 min-400 min. Moisture is dried to 5%-15% of a weight of the aerosol generating substrate, and then the dried aerosol generating substrate 30 may be taken out and obtained, which may be sucked when being heated.
The swelling agent may contain sodium bicarbonate (NaHCO3). The sodium bicarbonate may have a chemical reaction when being heated and is decomposed into sodium carbonate, carbon dioxide, and water, a chemical equation of which is as follows:
2NaHCO3Na2CO3+CO2(↑)+H2O.
The aerosol generating substrate swelling agent may contain disodium dihydrogen pyrophosphate (Na2H2P2O7) and sodium bicarbonate. The disodium dihydrogen pyrophosphate and the sodium bicarbonate have a chemical reaction when being heated, so as to generate sodium pyrophosphate (Na4P2O7), carbon dioxide, and water, a chemical reaction formula of which is as follows:
Na2H2P2O7+2NaHCO3Na4P2O7+2H2O+2CO2(↑).
In the drying process, the swelling agent in a raw material of the aerosol generating substrate 30 is heated and decomposed in the drying process so as to generate gas, such that the paste-like material substrate is puffed, a volume is increased, and a porous and loose paste-like structure with uniform pores is formed in the substrate.
In the drying process, a large amount of moisture contained in the paste-like material substrate is evaporated, such that a density and hardness of the aerosol generating substrate 30 are decreased, which is suitable for being inserted into a heating apparatus for heating.
A drying temperature of the drying device 820 for the aerosol generating substrate is set at a low temperature of 30° C.-80° C., such that the swelling agent in the paste-like material substrate may fully play a role, and a porous and loose structure may be generated in the aerosol generating substrate 30, so as to allow the aerosol to easily pass through. When the drying temperature is set to be excessively high, an evaporation speed of the moisture is high, such that the swelling agent of the paste-like material substrate is not fully puffed, and a dense hardened substrate is likely to be formed, which is not conducive to passage of the aerosol and insertion of the aerosol into the heating assembly of the heating apparatus.
The raw material of the aerosol generating substrate 30 includes substances such as flavor and fragrance and tobacco extract, which are easy to volatilize, deteriorate and lose at high temperature, so the drying temperature has not to be excessively high in the drying process.
As shown in
The drying device 822 for the aerosol generating substrate adds a heat convection method on the basis of the drying device 820 for the aerosol generating substrate, so that the temperature in the entire drying device is more uniform and consistent.
The drying device 822 for the aerosol generating substrate includes a box 410, a drying zone 412, a moisture discharge window 414, a reflux zone 416, a partition plate 418, a temperature and humidity sensor 420, a heat source 422, and a fan 424.
The partition plate 418 divides an interior of the box 410 into the drying zone 412 and the reflux zone 416. The moisture discharge window 414 is provided near an air inlet of the reflux zone 416. The temperature and humidity sensor 420 is arrange at a reflux opening of the reflux zone 416. The fan 424 is arranged near the heat source 422.
In the drying embodiment, the aerosol generating substrate to be dried is put into the drying zone 412 of the drying device 822 for the aerosol generating substrate, the fan 424 blows heat generated by the heat source 422 to the aerosol generating substrate to be dried in the drying zone 412, hot airflow heats the undried aerosol generating substrate and exchanges heat with the undried aerosol generating substrate, moisture in the undried aerosol generating substrate is evaporated and mixed with the hot airflow, and the hot airflow is changed to low-temperature airflow while being mixed with a large amount of moisture, such that a humidity is high. The low-temperature airflow flows to the reflux zone 416 through an inlet of the reflux zone, then flows back to the heat source 422 through the reflux opening, and is further heated and then blown to the aerosol generating substrate 30 to be baked in the drying zone 412, such that a temperature in the entire drying device is more uniform and consistent. When the low-temperature airflow flows through the temperature and humidity sensor 420 at the reflux opening, and the temperature and humidity sensor 420 measures the humidity of the low-temperature airflow. When the humidity is greater than a set value, the moisture discharge window 414 is opened to discharge the low-temperature airflow containing a large amount of moisture out of the box 410, such that drying of the undried aerosol generating substrate is accelerated.
In the drying device 822 for the aerosol generating substrate, a drying temperature is set at 30° C.-80° C., which is preferably 45° C.-65° C., drying time is 60 min-400 min. Moisture is dried to 5%-15% of a weight of the aerosol generating substrate, and then the dried aerosol generating substrate 30 may be taken out and obtained, which may be sucked when being heated.
A principle of the drying embodiment of the aerosol generating substrate 30 is the same as that of the above embodiment. Because the paste-like material substrate includes a swelling agent and a large amount of moisture, the aerosol generating substrate 30 may be fully puffed in the drying process, and the substrate having a porous and loose structure is generated.
As shown in
The drying device 824 for the aerosol generating substrate dries the undried aerosol generating substrate through microwave drying according to a microwave swelling principle, such that the aerosol generating substrate 30 has a feature of a porous structure.
The drying device 824 for the aerosol generating substrate includes a microwave box 430, a microwave generator 432, and a drying zone 434. In order to reduce air pressure in an oven, an evaporation temperature of water is reduced, and the drying process is accelerated. The drying device 824 for the aerosol generating substrate is further provided with a vacuum system 436.
A microwave frequency band selected by the drying device 824 for the aerosol generating substrate is an industrially used microwave frequency band of 915 MHz±5 MHz or 2450 MHz±5 MHz. An adjustable temperature range of a cavity of the microwave box 430 is 10° C.-100° C., and a vacuumizing range of the drying zone 434 is 0 KPa-101 KPa.
In the drying embodiment, the paste-like material substrate to be dried is put into the drying zone 434 of the drying device 824 for the aerosol generating substrate, a drying temperature is set at 30° C.-80° C., which is preferably 45° C.-65° C., a vacuum degree is set at 0 KPa-101 KPa, which is preferably 30 KPa-60 KPa, microwave power is adjusted according to an amount of the material put in, the power is adjusted to 0.8 KW-4.0 KW, which is preferably 1.0 KW-2.5 KW, and drying time is 10 min-60 min. Moisture is dried to 5%-15% of a weight of the aerosol generating substrate, and then the dried aerosol generating substrate 30 may be taken out and obtained, which may be sucked when being heated.
In order to further optimize a microwave drying procedure, in the drying process, the microwave drying procedure may be set to turn off microwave for a certain time after microwave drying for a certain time, then turn on microwave drying, and then turn off microwave drying, which is sequentially conducted in a circulating manner. Preferably, microwave baking time is 1 min-5 min, and microwave turn-off time is 1 min-3 min. After the aerosol generating substrate 30 is dried, the drying device 824 for the aerosol generating substrate is turned off, and the aerosol generating substrate 30 is taken out.
Generally, a substance is composed of polar molecules and nonpolar molecules. Under the action of a microwave electromagnetic field, the polar molecules in a medium change from an original thermal motion state to alignment and orientation following alternation of the microwave electromagnetic field. When microwave radiation is conducted on the paste-like aerosol generating substrate 30 at microwave frequency of 2450 MHz, the polar molecules in the paste-like aerosol generating substrate 30 may be arranged 2.45 billion times per second, and intense friction may occur between the molecules, such that heat is generated in the paste-like aerosol generating substrate 30, and electric energy may be directly converted into heat energy in the medium.
In the drying embodiment, microwave energy is converted into heat energy when reaching an interior of the undried paste-like aerosol generating substrate through radiation conduction of electromagnetic energy, such that water molecules in the undried paste-like aerosol generating substrate absorb microwave energy, and deep moisture in the undried paste-like aerosol generating substrate is quickly evaporated to form high internal vapor pressure. A microwave heating speed is very high, so a formation speed of vapor in the undried paste-like aerosol generating substrate is higher than a migration speed of the vapor, and a vapor pressure gradient appears in the undried paste-like aerosol generating substrate. When the pressure exceeds bearing capacity of structural strength of the undried paste-like aerosol generating substrate, the undried paste-like aerosol generating substrate is forced to puff, and a swelling force of gas drives structural modification of high molecular substances in the undried paste-like aerosol generating substrate, such that the undried paste-like aerosol generating substrate internally has the feature of the porous structure.
The moisture content has an obvious influence on microwave energy absorption capacity of the raw material in the undried paste-like aerosol substrate. The higher the moisture content in the undried paste-like aerosol substrate, the longer the evaporation time during swelling, which influences a swelling effect and production benefits. The lower the moisture content, the less possible it is to generate insufficient internal swelling pressure during swelling, which reduces a swelling rate of the paste-like aerosol substrate. In the embodiment of the present disclosure, the moisture content of the undried paste-like aerosol generating substrate accounts for 30%-60% of the weight of the undried paste-like aerosol generating substrate, such that a desirable swelling effect is achieved.
A boiling point temperature of water is related to air pressure. A boiling point of water varies while air pressure changes. Under the condition of a standard atmospheric pressure of 101 KPa, the boiling point temperature of the water is 100° C. With decrease of the air pressure, the boiling point temperature of the water may decrease. When the air pressure drops to 30 KPa-60 KPa, the boiling point temperature of the water drops to 40° C.-60° C.
In the drying embodiment, when the microwave box 430 is vacuumized, the evaporation temperature of the moisture in the undried paste-like aerosol generating substrate may be reduced. When the microwave box 430 is vacuumized to 30 KPa-60 KPa, the moisture in the undried paste-like aerosol generating substrate reaches the evaporation temperature at 40° C.-60° C., which further accelerates a formation speed of vapor in the undried paste-like aerosol generating substrate, and is conducive to the swelling effect of the undried paste-like aerosol generating substrate.
Further, in the embodiment, microwave drying may also be conducted by combining vacuum microwave drying and atmospheric microwave drying. In the process of microwave drying, firstly, the drying device 824 for the aerosol generating substrate conducts vacuum microwave drying for 1 min-5 min, then the interior of the drying device 824 for the aerosol generating substrate is released to reach an atmospheric pressure for atmospheric pressure microwave drying for 1 min-5 min, then the drying device 824 for the aerosol generating substrate conducts vacuum microwave drying for 1 min-5 min, and then the vacuum microwave drying is switched to atmospheric pressure microwave drying for 1 min-5 min, which are repeated in the same manner until the aerosol generating substrate 30 is dried.
Further, in the embodiment, the microwave device may further include a rotating mechanism. The rotating mechanism may further include a placing tray. The undried aerosol generating substrate is placed on the placing tray in the rotating mechanism. The rotating mechanism drives the placing tray to rotate in the microwave device during microwave baking, such that the aerosol generating substrate may be heated uniformly in the microwave device.
Microwave drying may quickly evaporate the moisture in the undried aerosol generating substrate, and meanwhile, the paste-like material may be quickly puffed and adhere to an inner wall of the packaging material 32, such that an integrated loose and porous structure is formed. Because the paste-like material contains a large amount of moisture, a large number of micropores are generated in the aerosol generating substrate 30 after the material is puffed and the moisture is evaporated, and a micropore porosity reaches 40%-75%.
In the drying process, the swelling agent in the raw material of the aerosol generating substrate 30 is heated and decomposed in the drying process so as to generate gas, such that the undried paste-like aerosol generating substrate is puffed, a volume is increased, and a porous and loose structure with uniform pores is formed. The principle that the swelling agent of the aerosol generating substrate 30 is heated and decomposed to generate gas is described in the above embodiments, which will not be repeated herein.
In the drying process, a large amount of moisture contained in the raw material of the aerosol generating substrate 30 is evaporated, such that a density and hardness of the aerosol generating substrate 30 are decreased, which is suitable for being inserted into the heating apparatus for heating.
In the drying embodiment, a microwave swelling technology, a principle of lowering a boiling point of moisture under low pressure and a swelling effect of the swelling agent in the raw material of the aerosol generating substrate 30 are fully exerted, such that gaps in the aerosol generating substrate 30 are more uniform and the structure is porous and loose. The hardness of the dried aerosol generating substrate 30 is within a range of 0.5 kgf-2.5 kgf. A force of inserting the aerosol generating substrate into the heating apparatus is appropriate, which does not lead to the situation that the aerosol generating substrate 30 is hardened and cannot be inserted into the heating part of the heating apparatus in the drying process.
In the drying embodiment, the drying temperature of microwave is also set at 30° C.-80° C., which is preferably 45° C.-65° C., such that the components such as flavor and fragrance and tobacco extract in the raw material of the aerosol generating substrate 30 are effectively preserved, and the components such as the flavor and fragrance and the tobacco extract in the raw material of the aerosol generating substrate 30 are prevented from being greatly volatilized, deteriorating or being lost, so as to ensure smoking flavor of the aerosol generating substrate 30.
In the drying embodiment of the aerosol generating substrate 30, microwave drying and heat convection drying may also be used. Firstly, the undried aerosol generating substrate 30 is subjected to preliminary microwave drying with the drying device 824 for the aerosol generating substrate according to the method in the embodiment, such that the aerosol generating substrate 30 is puffed under the microwave action, and meanwhile, 10%-60% of the moisture in the undried aerosol generating substrate is removed. The semi-dried aerosol generating substrate 30 is taken out and cooled to 20° C.-25° C. Then, the semi-dried aerosol generating substrate 30 is put into the drying device 822 for the aerosol generating substrate, and the moisture in the semi-dried aerosol generating substrate 30 is dried to 5%-15% of the weight of the aerosol generating substrate according to the method in the above embodiment. The dried aerosol generating substrate is taken out and obtained.
By combining microwave drying of the drying device 824 for the aerosol generating substrate and heat convection drying of the drying device 822 for the aerosol generating substrate, the advantages of the two drying methods may be fully exerted. Microwave drying has the advantages of high drying efficiency and a microwave swelling effect, which may quickly remove the moisture in the undried aerosol generating substrate 30, so as to implement swelling. Meanwhile, the semi-dried aerosol generating substrate 30 is further dried through heat convection baking, which may make the internal structure of the dried aerosol generating substrate 30 more uniform and the drying process more stable and controllable.
In the drying embodiment of the aerosol generating substrate 30, a microwave drying step may also be conducted by combining vacuum microwave drying and atmospheric pressure microwave drying in the above embodiment. The undried aerosol generating substrate 30 is dried through heat convection drying after removal of 10%-60% of the moisture through microwave swelling.

In the embodiment, the drying device 826 for the aerosol generating substrate uses vacuum drying, and heats the undried aerosol generating substrate 30 in vacuum, such that the boiling point of the moisture in the undried aerosol generating substrate 30 is decreased, and the drying speed of the undried aerosol generating substrate 30 is accelerated.
The drying device 826 for the aerosol generating substrate includes a box 440, a drying zone 442, a heat source 444, and a vacuum pump system 446.
In the drying embodiment, the undried aerosol generating substrate 30 is placed in the drying zone 442, a drying temperature is set at 30° C.-80° C., which is preferably 45° C.-65° C., a vacuum degree is set at 10 KPa-90 KPa, which is preferably 30 KPa-60 KPa, and time is set at 30 min-900 min. An apparatus is started to conduct vacuum drying on the undried aerosol generating substrate 30. Vacuumizing may be dehumidification by starting the vacuum pump. When the moisture of the aerosol generating substrate is dried to 5%-15% of the weight of the aerosol generating substrate, the dried aerosol generating substrate 30 is taken out, and the dried aerosol generating substrate 30 may be obtained, which may be sucked when being heated.
Because vacuum drying belongs to static vacuum drying, a shape of the aerosol generating substrate 30 may not be damaged. Meanwhile, because the drying temperature is relatively low, within a range of 30° C.-80° C., the aerosol generating substrate 30 may not be hardened after drying.
In the drying process, the swelling agent in a raw material of the aerosol generating substrate 30 is heated and decomposed to generate gas, such that the paste-like aerosol generating substrate 30 is puffed, a volume is increased, a structure is soft and loose, and a porous and loose structure with uniform pores is formed. The principle that the swelling agent of the aerosol generating substrate 30 is heated and decomposed to generate gas is described in the above embodiment, which will not be repeated herein.
In the drying process, a large amount of moisture contained in the raw material of the aerosol generating substrate 30 is evaporated, such that a density and hardness of the aerosol generating substrate 30 are decreased, which is suitable for being inserted into the heating apparatus for heating.
In the drying embodiment of the aerosol generating substrate 30, microwave drying and vacuum drying may also be used. Firstly, the undried aerosol generating substrate 30 is subjected to preliminary microwave drying with the drying device 824 for the aerosol generating substrate according to the method in the embodiment, such that the undried aerosol generating substrate 30 is puffed under the microwave action, and meanwhile, 10%-60% of the moisture in the undried aerosol generating substrate 30 is removed. The semi-dried aerosol generating substrate 30 is taken out and cooled to 20° C.-25° C. Then, the semi-dried aerosol generating substrate 30 is put into the drying device 826 for the aerosol generating substrate, and the moisture in the semi-dried aerosol generating substrate 30 is dried to 5%-15% of the weight of the aerosol generating substrate 30 according to the method in the above embodiment. The aerosol generating substrate 30 is taken and the dried aerosol generating substrate 30 is obtained.
By combining microwave drying of the drying device 824 for the aerosol generating substrate and vacuum drying of the drying device 826 for the aerosol generating substrate, the advantages of the two drying methods may be fully exerted. Microwave drying is high in drying efficiency and desirable in microwave swelling effect, which may quickly remove the moisture in the undried aerosol generating substrate 30, so as to implement swelling. Meanwhile, the semi-dried aerosol generating substrate 30 is further dried through vacuum drying. Because vacuum drying belongs to static vacuum drying, a shape of the aerosol generating substrate 30 may not be damaged, which may make the internal structure of the aerosol generating substrate 30 more uniform and the drying process more stable and controllable, and meanwhile, achieve microwave insecticidal sterilization.
In the drying embodiment of the aerosol generating substrate 30, a microwave drying step may also be conducted by combining vacuum microwave drying and atmospheric pressure microwave drying in the above embodiment. The undried aerosol generating substrate 30 is dried through vacuum drying after removal of 10%-60% of the moisture through microwave swelling.

The drying device 828 for the aerosol generating substrate uses a freeze-drying method. The freeze-drying method is a technology of drying according to a sublimation principle, which is a process of quickly freezing the dried substances at low temperature, and then directly subliming the frozen water into vapor to escape in a proper vacuum environment. A product obtained through freeze-drying is referred to as a freeze-dried object, and the process is referred to as freeze-drying. The substance is at the low temperature all the time (in a frozen state) before drying, and meanwhile, ice crystals are uniformly distributed in the substance. Concentration caused by dehydration may not occur in a sublimation process, such that side effects such as foam and oxidation caused by water vapor are avoided. The dry substance is porous like a dry sponge and has a basically unchanged volume, which prevents physical, chemical and biological degeneration of the dry substance to the greatest extent.
The drying device 828 for the aerosol generating substrate includes a vacuum drying box 450, a drying zone 452 in the vacuum drying box 450, a heat source 454 in the vacuum drying box 450, a vacuum system 456 for vacuumizing the vacuum drying box 450, a freezing box 458, a freezing zone 460 in the freezing box 458, and a refrigeration system 462 for freezing a material in the freezing box 458.
In the embodiment, firstly, the undried aerosol generating substrate 30 is put into the freezing zone 460 in the freezing box 458, and the refrigeration system 462 is started to freeze the undried aerosol generating substrate 30 to −55° C.-0° C., such that the undried aerosol generating substrate 30 is completely crystallized and then taken out, and the crystallized aerosol generating substrate 30 is obtained. In this case, the moisture in the crystallized aerosol generating substrate 30 changes to ice crystals, which are uniformly distributed in the crystallized aerosol generating substrate 30, and then put into the drying zone 452 in the vacuum drying box 450 for vacuum drying.
A drying temperature of the vacuum drying box 450 is set at 30° C.-80° C., which is preferably 45° C.-65° C. A vacuum degree is set at 10 KPa-90 KPa, which is preferably 30 KPa-60 KPa. Time is set at 30 min-900 min. An apparatus is started to conduct vacuum drying on the crystallized aerosol generating substrate 30. The crystallized aerosol generating substrate 30 is at the low temperature all the time (in a frozen state) before drying, and meanwhile, the ice crystals are uniformly distributed in the crystallized aerosol generating substrate 30, and the ice crystals are heated and sublimated, such that concentration caused by dehydration may not occur in the drying and sublimation process, and side effects such as foam and oxidation caused by water vapor are avoided. The dried aerosol generating substrate 30 is spongy and porous and has a basically unchanged volume, which prevents physical, chemical and biological degeneration of the aerosol generating substrate 30 to the greatest extent. When the moisture in the aerosol generating substrate 30 is dried to 5%-15% of the weight of the aerosol generating substrate 30, the dried aerosol generating substrate 30 is obtained, which may be sucked when being heated.
The aerosol generating substrate is dried through the freeze-drying technology, the aerosol generating substrate does not shrink or expand, and an interior of the aerosol generating substrate is spongy and porous, such that aerosol generated by heating the aerosol generating substrate may pass smoothly. Meanwhile, because the aerosol generating substrate is dried at the low temperature, the situation that the aerosol generating substrate is hardened and cannot be inserted into a heating part of a heating apparatus can be avoided. The aerosol generating substrate obtained through the freeze-drying method has hardness of 0.5 kgf-2.5 kgf, and may be easily inserted into the heating part of the heating apparatus.
In the drying process, the swelling agent in a raw material of the aerosol generating substrate 30 is heated and decomposed to generate gas, such that the paste-like aerosol generating substrate 30 is puffed, a volume is increased, a structure is soft and loose, and a porous and loose structure with uniform pores is formed. The principle that the swelling agent of the aerosol generating substrate 30 is heated and decomposed to generate gas is described in the above embodiment, which will not be repeated herein.
In the drying process, a large amount of moisture contained in the raw material of the aerosol generating substrate 30 is evaporated, such that a density and hardness of the aerosol generating substrate 30 are decreased, which is suitable for being inserted into the heating apparatus for heating.
In the drying embodiment of the aerosol generating substrate 30, microwave drying and freeze drying may also be used. Firstly, the undried aerosol generating substrate 30 is subjected to preliminary microwave drying with the drying device 824 for the aerosol generating substrate according to the method in the embodiment, such that the undried aerosol generating substrate 30 is puffed under the microwave action, and meanwhile, 10%-60% of the moisture in the aerosol generating substrate 30 is removed. The semi-dried aerosol generating substrate 30 is taken out, then the semi-dried aerosol generating substrate 30 is put into the freezing zone 460 in the freezing box 458 in the drying device 828, and the refrigeration system 462 is started to freeze the semi-dried aerosol generating substrate 30 to −55° C.-0° C., such that the moisture in the semi-dried aerosol generating substrate 30 is completely crystallized and then the aerosol generating substrate is taken out, and the crystallized aerosol generating substrate 30 is obtained. Then, the aerosol generating substrate is put into the drying zone 452 in the vacuum drying box 450, and the moisture in the crystallized aerosol generating substrate 30 is dried to 5%-15% of the weight of the aerosol generating substrate 30 according to the method in the above embodiment, such that the dried aerosol generating substrate 30 is obtained.
By combining microwave drying of the drying device 824 for the aerosol generating substrate and freeze drying of the drying device 828 for the aerosol generating substrate, the advantages of the two drying methods may be fully exerted. Microwave drying is high in drying efficiency and desirable in microwave swelling effect, which may quickly remove the moisture in the undried aerosol generating substrate 30, so as to implement swelling. Meanwhile, the crystallized aerosol generating substrate 30 is further dried through freeze drying. The moisture in the crystallized aerosol generating substrate 30 is at the low temperature all the time (in a frozen state) before drying, and meanwhile, the ice crystals are uniformly distributed in the crystallized aerosol generating substrate 30, such that concentration caused by dehydration may not occur in the sublimation process, and side effects such as foam and oxidation caused by water vapor are avoided. The dried aerosol generating substrate 30 is porous like a dry sponge and has a basically unchanged volume, which prevents physical, chemical and biological degeneration of the aerosol generating substrate 30 to the greatest extent.
In the drying embodiment of the aerosol generating substrate 30, the undried aerosol generating substrate 30 may be put into the freezing zone 460 in the freezing box 458 in the drying device 828, and the undried aerosol generating substrate 30 is frozen to −55° C.-0° C., such that the moisture in the undried aerosol generating substrate 30 is completely crystallized and then the aerosol generating substrate is taken out, and the completely crystallized aerosol generating substrate 30 is obtained. Then, the crystallized aerosol generating substrate 30 is put into the drying device 824 and subjected to microwave drying according to the method in the above embodiment. The microwave drying process is conducted through vacuumizing. When the moisture in the aerosol generating substrate 30 is dried to 5%-15% of the weight of the aerosol generating substrate 30, the dried aerosol generating substrate is obtained.
In the drying embodiment, before microwave baking and drying, the undried aerosol generating substrate 30 is frozen, and then dried through vacuum microwave drying. The aerosol generating substrate 30 is at the low temperature all the time (in a frozen state) before drying, and meanwhile, ice crystals are uniformly distributed in the substance, such that concentration caused by dehydration may not occur in a sublimation process, and side effects such as foam and oxidation caused by water vapor are avoided. Meanwhile, due to high microwave drying efficiency, the moisture in the aerosol generating substrate 30 may be quickly removed, and effects of accelerating drying and insecticidal sterilization may be achieved.
In the drying embodiment of the aerosol generating substrate 30, the undried aerosol generating substrate 30 may also be put into the freezing zone 460 in the freezing box 458 in the drying device 828, and the aerosol generating substrate 30 is frozen to −55° C.-0° C. The aerosol generating substrate 30 is taken out after being completely crystallized, and the crystallized aerosol generating substrate 30 is obtained. Then, the crystallized aerosol generating substrate 30 is put into the drying device 824 and subjected to microwave drying according to the method in the above embodiment, such that the crystallized aerosol generating substrate 30 is puffed under the microwave action, and meanwhile, 10%-60% of the moisture in the crystallized aerosol generating substrate 30 is removed. The semi-dried aerosol generating substrate 30 is obtained. Then, the semi-dried aerosol generating substrate 30 is taken out, and then the semi-dried aerosol generating substrate 30 is put into the drying zone 452 in the vacuum drying box 450 in the drying device 828. The moisture in the aerosol generating substrate 30 is dried to 5%-15% of the weight of the aerosol generating substrate 30 according to the method in the above embodiment. The dried aerosol generating substrate 30 is obtained.
In the drying embodiment, the aerosol generating substrate 30 is frozen before microwave drying, and then dried through vacuum microwave drying, such that a large amount of moisture is removed from the aerosol generating substrate 30. Then, the aerosol generating substrate is dried in a vacuum drying box, such that vacuum drying time can be greatly shortened, and insecticidal sterilization is achieved while the internal loose structure of the aerosol generating substrate 30 is more uniform.
In the above embodiment, polar molecules are violently moved in a microwave drying process, such that heat is instantaneously generated in the aerosol generating substrate, and then vapor pressure is generated in the aerosol generating substrate. In this way, a vapor pressure gradient appears in the paste-like aerosol generating substrate, so as to force the paste-like aerosol generating substrate to puff, and structural modification of high molecular substances in the paste-like aerosol generating substrate 30 is driven by a swelling force of gas.
The aerosol generating substrate 30 obtained in the drying embodiments of the above several aerosol generating substrates 30 has a soft structure and a porous and loose internal structure, which makes a smaller density. A distribution range of the density is 0.10 g/cm3-0.90 g/cm3.
The material may be dried through various methods. Traditional heating methods (heat conduction, convection and radiation) all heat and dry the material from outside to inside. The present disclosure provides another embodiment of a manufacturing method for an aerosol generating substrate. The manufacturing method includes the following steps: a metal material is added into a raw material formula, and the metal material in the aerosol generating substrate is heated through a high-frequency induction technology in the drying process of the aerosol generating substrate, such that the aerosol generating substrate is uniformly heated from the inside, and the drying process can be accelerated.
In the embodiment, the metal material is added into the raw material of the aerosol generating substrate 30, such that under the action of high-frequency waves in the subsequent high-frequency induction drying device, an induction current having the same frequency is formed on a surface of the metal material. Then, heat is quickly generated, such that the inside of the aerosol generating substrate 30 is heated by the metal material, and a drying effect is achieved.
In the embodiment, the manufacturing method for an aerosol generating substrate includes three steps: a paste-like material of the aerosol generating substrate is manufactured, the paste-like material is made into a shape of the aerosol generating substrate, and the aerosol generating substrate is dried. Further, in the embodiment, the manufacturing method for an aerosol generating product includes three steps: a paste-like material of the aerosol generating substrate is manufactured, the paste-like material is molded into a shape of the aerosol generating substrate, and a semi-manufactured product of the aerosol generating product is dried. In the step that the semi-manufactured product of the aerosol generating product is dried, undried aerosol generating substrates 114, 120, 124 and 128 may be put into a drying device for drying and then put into a packaging material 40. Alternatively, undried aerosol generating substrates 118, 112, 126, 130 and 134 may be put into a drying device for drying. The undried aerosol generating substrates 118, 112, 126, 130 and 134 are wrapped in a tubular packaging material 40, such that other assemblies, such as a filtering assembly, a flavor assembly, a cooling assembly or a susceptor assembly, may be selectively used to fill a space where the tubular packaging material 40 is not filled with the paste-like material.
In the embodiment, the manufacturing method for the paste-like material of the aerosol generating substrate was as follows:
Step one, 40 parts-80 parts of crushed and mixed raw materials, 10 parts-20 parts of tobacco extract, 30 parts-60 parts of aerosol generating agents, 10 parts-30 parts of flavor and fragrance, 1 part-5 parts of aerosol substrate forming agents, 1 part-3 parts of aerosol substrate swelling agents, 1 part-10 parts of aerosol sustained-release agents, 30 parts-50 parts of water and 1 part-10 parts of metal materials were taken, mixed and stirred, and then uniformly stirred with a stirrer, so as to form wet paste.
Step two, after manufacturing of the paste-like material of the aerosol generating substrate 30 was completed, the paste-like material was started to be molded into the aerosol generating substrate 30. The molding method for the aerosol generating substrate 30 according to the present disclosure was the same as that for the aerosol generating substrate 30 in the above embodiment, which obtained the aerosol generating substrate 30 with the metal material. The drawing of the above embodiment is cited to describe the molding method.

Step three, after the paste-like material with the metal material was manufactured into the aerosol generating substrate 30, the same drying method as the above drying embodiment of the aerosol generating substrate 30 may be used to obtain the corresponding dried aerosol generating substrate.
With reference to
The drying device 830 for the aerosol generating substrate includes an inductor oven 468 and a high-frequency power supply 466. The high-frequency power supply 466 provides high-frequency power for the inductor oven 468. A power supply frequency is 100 KHZ-500 KHZ. The inductor oven 468 is an inductor formed by winding a hollow copper tube. After the high-frequency power supply is turned on, the inductor oven 466 generates high-frequency waves. Under the action of the high-frequency waves, an induced current with the same frequency is formed on a surface of the metal material in the aerosol generating substrate with the metal material, so as to rapidly generate heat. The metal material is uniformly distributed in the material, such that the material is uniformly heated from the inside, so as to achieve a rapid drying effect.
The to-be-dried aerosol generating substrate with the metal material is put into the inductor oven 468. A temperature of the inductor oven 468 is set at 30° C.-80° C., and preferably 45° C.-65° C. Power output from the high-frequency power supply 466 to the inductor oven 468 is 0.8 KW-4.0 KW for each kilogram of material, and preferably 1.0 KW-2.5 KW. Drying time is set at 100 min-600 min. The inductor oven 468 is connected to the high-frequency power supply 466. The power supply frequency is 100 KHZ-500 KHZ. The inductor oven 468 generates high-frequency waves. Under the action of the high-frequency waves, the induced current with the same frequency is formed on the surface of the metal material in the aerosol generating substrate with the metal material, and heat is generated rapidly.
In the drying process, the metal material in the aerosol generating substrate generates heat under the action of the high-frequency waves in the inductor oven 468, so as to heat the aerosol generating substrate from the inside. The swelling agent in the raw material of the aerosol generating substrate is heated and decomposed to generate gas, such that the paste-like aerosol generating substrate is puffed, a volume is increased, a structure is soft and loose, and a porous and loose structure with uniform pores is formed.
In the drying process, a large amount of moisture contained in the raw material of the aerosol generating substrate is evaporated, such that a density and hardness of the aerosol generating substrate are decreased, which is suitable for being inserted into the heating apparatus for heating.
Finally, after the moisture in the aerosol generating substrate is dried to 5%-15% of the weight of the aerosol generating substrate, the dried aerosol generating substrate is obtained, which may be sucked when being heated.
Further, according to a principle that a boiling point of liquid drops under low pressure, the inductor oven 468 of the drying device 830 for the aerosol generating substrate may be vacuumized to accelerate the drying process of the aerosol generating substrate 30 with the metal material.
In the drying embodiment of the aerosol generating substrate 30 of the present disclosure, drying with high-frequency waves has many advantages as follows.
First, rapid heating and high efficiency are achieved. When the aerosol generating substrate 30 with the metal material is put into the inductor oven 468 and the high-frequency power supply is turned on to start baking, the metal material in the aerosol generating substrate 30 generates heat immediately under the action of the high-frequency waves, and inside and outside of the aerosol generating substrate 30 reach a heating temperature instantly.
Second, uniform heating is achieved. The metal material is uniformly distributed in the aerosol generating substrate 30, such that heat energy may be simultaneously generated inside and outside the aerosol generating substrate 30, and the aerosol generating substrate with undried inside and burnt outside is not generated. With continuous evaporation of moisture on the surface of the aerosol generating substrate 30, the temperature on the surface of the aerosol generating substrate 30 is slightly lower than an inner layer temperature, and a temperature gradient is formed from the inside to the outside, which has a consistent direction with vapor pressure migration and heat migration accompanying the heating process. According to a material drying theory, the heating state is very conducive to material drying.
Third, the method is small in thermal inertia, instantaneous in heating and easy to control. Energy output by the high-frequency waves is immediately absorbed by the metal material in the aerosol generating substrate 30 for heating. Heating may be immediately implemented or terminated as long as the power of the high-frequency power supply is controlled, in which no preheating process is required.
Fourth, the high-frequency waves have a insecticidal sterilization function. Under the action of high-frequency microwave in the inductor oven 468 of the drying device 830 for the aerosol generating substrate, pests and bacteria in the aerosol generating substrate 30 may be killed, such that the insecticidal sterilization function can be achieved.
It may be seen from the above description that the aerosol generating substrate 30 with the metal material may be dried through high-frequency induction drying with the drying device 830 for the aerosol generating substrate, such that the inside of the aerosol generating substrate with the metal material may generate heat uniformly. In this way, drying efficiency is higher, a heating effect is better, consistency of the material is better, and porosity distribution is more uniform.

The dried aerosol generating substrate obtained in the above embodiment has characteristics of low hardness, porous sponge-like inside, low moisture content, columnar integrated substrate, etc., such that the aerosol generating substrate 30, the aerosol generating substrate 132 with the tubular packaging material and the aerosol generating substrate 136 with the tubular packaging material may be inserted into the heating part of the heating apparatus. The heat generated by the heating part of the heating apparatus has a desirable heat transfer effect in the aerosol generating substrate 30, the aerosol generating substrate 132 with the tubular packaging material and the aerosol generating substrate 136 with the tubular packaging material, which are uniformly heated. The aerosol generated by heating the aerosol generating substrate 30, the aerosol generating substrate 132 with the tubular packaging material and the aerosol generating substrate 136 with the tubular packaging material with the heating apparatus may smoothly pass through the internal porous gaps, and meanwhile, a suitable suction resistance is provided, such that the aerosol sucked into a mouth of a consumer is moderate in temperature and is suitable for being sucked by the consumer.
The aerosol generating substrate 30, the aerosol generating substrate 132 with the tubular packaging material and the aerosol generating substrate 136 with the tubular packaging material that are obtained through the above drying methods have soft structures and porous and loose internal structures. The raw materials include metal materials, such that the aerosol generating substrate is heavy. The density distribution range of the aerosol generating substrate, except the metal material, is 0.10 g/cm3-0.90 g/cm3.
The metal materials added to the aerosol generating substrate 30, the aerosol generating substrate 132 with the tubular packaging material and the aerosol generating substrate 136 with the tubular packaging material may be magnetic materials, or metal materials and magnetic materials. A formation method, a drying method, a drying principle and effects of the paste are the same as structures and suction effects of the formed aerosol generating substrate 30, the formed aerosol generating substrate 132 with the tubular packaging material and the formed aerosol generating substrate 136 with the tubular packaging material.
The aerosol generating product containing the metal material, the aerosol generating product containing the magnetic material and the aerosol generating product containing the metal material and the magnetic material may generate heat by themselves under the action of a changing magnetic field, such that the aerosol generating substrate 30, the aerosol generating substrate 132 with the tubular packaging material and the aerosol generating substrate 136 with the tubular packaging material are heated to generate the aerosol. The aerosol generating product may also be heated by an electromagnetic induction heater for suction, without being inserted into the heating part of the heating apparatus for heating, such that no aerosol generating substrate 30 is left on the heating part when the aerosol generating substrate is pulled out, which is conducive to cleaning of the heating apparatus. Meanwhile, when the aerosol generating product is heated through electromagnetic induction, the electromagnetic susceptor generates heat uniformly, such that the aerosol generating substrate 30, the aerosol generating substrate 132 with the tubular packaging material and the aerosol generating substrate 136 with the tubular packaging material are heated uniformly, and a better suction effect can be achieved.
In addition to the above drying embodiment, the aerosol generating substrate may also be dried with other dryers, such as a rotary dryer, a roller dryer, a tunnel microwave dryer, a tunnel dryer, a mesh band tunnel oven, a vacuum rake dryer, a double-cone vacuum dryer, and a low-temperature single-cone vacuum dryer. The aerosol substrate 30 may also achieve purposes of swelling and loose structure through appropriate temperature and time, and additional vacuumizing. There are various drying methods, which will not be listed one by one herein. As long as the drying method achieves the required drying purpose, the drying method may be used.
The aerosol generating substrate obtained in the above embodiment internally includes crystal blocks and plant fiber filaments. The plant fiber filaments are not uniformly distributed between the crystal blocks. The crystal block includes plant raw material powder and an aerosol substrate forming agent, and is formed in a process of molding and drying the aerosol generating substrate. The crystal blocks have an irregular shape and size. The crystal blocks mutually adhere to form an integral aerosol generating substrate. When the aerosol generating substrate further includes the packaging material in the molding process, the crystal block in contact with the packaging material still adheres to the packaging material. Gaps distributed not uniformly and having irregular sizes exist between the crystal blocks, and a porosity between the crystal blocks is 45%-70%, such that the porous and loose structure is formed. Liquid raw materials, such as the aerosol generating agent, the tobacco extract, the flavor and fragrance and water, in the aerosol generating substrate permeate into the crystal blocks and the plant fiber filaments. Glycerinum is a commonly used aerosol generating agent. When the glycerinum is used as the aerosol generating agent, the glycerinum may permeate into the crystal blocks and the plant fiber filaments.
The aerosol generating substrate includes the crystal blocks and the plant fiber filaments. A water content of the crystal blocks after drying is 3%-15%. A total weight of the crystal blocks accounts for more than 10% of a total weight of the aerosol generating substrate.
After drying, the moisture in the aerosol generating substrate is evaporated. In the drying process, the paste in the aerosol generating substrate is puffed, and the aerosol generating substrate having a low density is obtained. A density range of a part excluding the packaging material and the metal material is 0.1 g/ml-0.9 g/ml.
Although the dried aerosol generating substrate obtained in the above embodiment is internally loose and porous and the internal gaps allow the aerosol generated through heating to pass through, the gaps are relatively small, and no through hole is provided from one end to the other end of the aerosol generating substrate. In this case, the suction resistance of the aerosol generating substrate is large when the aerosol generating substrate is unheated, which is larger than that of a traditional heat-not-burn cigarette. In addition, in the dried aerosol generating substrate obtained in the above embodiment, a weight ratio of the aerosol generating agent in the aerosol generating substrate to the aerosol generating substrate is 1%-12%.
According to definitions and standard conditions recommended by the Cooperation Centre for Scientific Research Relative to Tobacco (CORESTA) for generation and collection of No 81 e-cigarette aerosol, a suction resistance is tested with a smoking machine. Test conditions are as follows: an ambient temperature for suction is 22° C.±2° C., a relative humidity is 60% 5%, a maximum suction speed is 18.5 ml/s±1 ml/s, a suction frequency is 30 s±0.5 s, a suction volume is 55 ml±0.3 ml, suction duration is 3 s±0.1 s, a suction waveform is square-wave, and a pressure drop of the smoking machine is ≤300 Pa. When suction resistances of a traditional cigarette and an e-cigarette are tested according to the above conditions, the suction resistance is mostly be lower than 1.0 Kpa, even lower than 0.8 KPa, or lower than 0.5 KPa, and rarely higher than 2.0 KPa. When the aerosol generating substrate obtained in the above embodiment is additionally provided with the packaging material and then heated and directly sucked, the suction resistance is generally greater than that of the traditional cigarette and the e-cigarette. The suction resistance higher than 2.0 KPa accounts for 50% or above. The suction resistance higher than 1.0 KPa accounts for 70% or above. The suction resistance may exceed 2.5 KPa, or 3.0 KPa, or 4.0 KPa. A range of the suction resistance is 1.0 KPa-5.0 KPa.
When the aerosol generating substrate is heated and sucked, a first suction resistance is relatively large, which may exceed 1.5 KPa, or 2.0 KPa, or 3.0 KPa. After the first time of suction, the suction resistance gradually decreases. After 3 times-4 times of suction, the suction resistance decreases to about 1.0 KPa, which is more conducive to suction of a smoker.

In the embodiment, the cooling assembly 38 may cool the aerosol generated by heating the aerosol generating substrate 30. Since a temperature of the aerosol generated by heating the aerosol generating substrate 30 is relatively high, the cooling assembly 38 may lower the temperature of the passing aerosol, such that the aerosol may be more suitable for being sucked by smoker.

The inside or surface of the cooling assembly 38 is provided with a through hole, which can also be a porous structure or a porous sponge-like structure allowing the aerosol to pass through.

In the aerosol generating substrate 30 in the above embodiment, the moisture content of the aerosol generating substrate is 5%-15%, so the temperature of the aerosol generated by heating the aerosol generating substrate 30 is low, which may provide the temperature for preventing the smoker from scalding when sucking the aerosol. At least one of the filtering assembly 34, the flavor assembly 36 and the cooling assembly 38 is added to a rear section of the aerosol generating substrate 30. After the aerosol generated by heating the aerosol generating substrate 30 passes through at least one of the filtering assembly 34, the flavor assembly 36 and the cooling assembly 38, the temperature of the aerosol becomes lower, such that the aerosol is more suitable for being sucked by the smoker.

A surface of the susceptor 162 may also be covered with a protective material, and for instance, a protective ceramic layer, a protective Teflon coating, and a protective glass layer; or electroplated with an inert metal protective layer, and for instance, electroplated a ferrite surface with a nickel layer.
When the susceptor 162 is made of a plurality of different materials, the susceptor may have different curie temperatures. The susceptors having different curie temperatures may be referred to as heating susceptors and temperature control susceptors respectively. The heating susceptors have a heating curie temperature for heating the susceptors to a certain temperature. The temperature control susceptors have a temperature control curie temperature for controlling the susceptors in a certain temperature range. When the temperature control susceptor is heated to the temperature control curie temperature, a magnetic property of the temperature control susceptor changes, and the susceptor material changes reversibly from ferromagnetic phase to paramagnetic phase. In an induction heating process of the aerosol generating substrate, phase change of the temperature control susceptor material may be detected online, such that induction heating may be automatically stopped. Therefore, even when a heating curie temperature of a heating susceptor is higher than the temperature control curie temperature, the heating susceptor stops heating as an apparatus automatically stops induction heating, such that the aerosol generating substrate is prevented from being overheated and burnt locally. After induction heating is stopped, when the temperature control susceptor is cooled to a temperature below the temperature control curie temperature, the temperature control susceptor is recovered to the ferromagnetic property, and phase change is detected online, such that induction heating is re-activated.
Certainly, when only one type of susceptor is provided, the heating curie temperature is the temperature control curie temperature, and the susceptor has both a heating function and a temperature control function. Certainly, if the heating susceptor and the temperature control susceptor are separated and a temperature difference between the heating curie temperature and the temperature control curie temperature is great enough, the heating temperature may be effectively controlled to prevent the aerosol generating substrate from being overheated and burnt locally.
When the susceptor 162 is heated, resistance of the susceptor may increase or decrease. When susceptors of different materials are selected, materials having the same resistance-temperature coefficient or materials having different resistance-temperature coefficients may be selected, such that similar effects may be achieved.
The susceptor 162 may be arranged near the aerosol generating substrate, around the aerosol generating substrate 30, or in the aerosol generating substrate 30. At least part of the susceptor 162 is in contact with the aerosol generating substrate. When the susceptor 162 is completely wrapped in the aerosol generating substrate in a contacted manner, optimal heat conduction is implemented, and a heating effect is optimal.
In some embodiments of the present disclosure, the aerosol generating substrate 30 internally has a porous and loose structure, and internally has small gaps, such that a desirable heat conduction effect and uniform heating are achieved. An effect of faster and uniform heating can be achieved by matching the susceptor assembly 39.

As shown in
In practical application, one or more susceptors 162 are arranged in the aerosol generating substrate 30 at the same position or at different positions along an end surface of the aerosol generating substrate 30, such that at least one or more slot openings 164 may be generated.
In order to make smell of the aerosol generated from the aerosol generating product in a heating and suction process of a heating assembly of a heater more pleasing with less miscellaneous gas, the assembled aerosol generating product may also use high-frequency induction alcoholization.
Although a plant raw material of the aerosol generating substrate 30 is subjected to natural fermentation or fermenting-enzyme fermentation, a macromolecular structure in the plant raw material may be decomposed into micromolecular structures, and not all the macromolecular structures in the plant raw material may be decomposed into micromolecular structures. In order to further decompose the macromolecular structure in the plant raw material, the aerosol generating product may be subjected to high-frequency induction alcoholization after assembly, such that the macromolecular structure in the aerosol generating product may be further split, and alcoholization of the aerosol generating product may be implemented.
The plant raw material of the aerosol generating substrate 30 is composed of groups having large molecular structures, and the macromolecular structure has relatively strong smell, which may hardly be covered with the flavor and fragrance. For instance, a protein content in tea leaves reaches 21%-28%, which may produce pungent feeling, enhanced irritation, increased bitterness and unpleasing protein odor in the heating process.
Protein and other substances in the raw material may be decomposed into other micromolecular substances through high-frequency wave radiation. For instance, tea leaves contain tea polyphenol, tea pigment, tea polysaccharide, tea saponin, protein, amino acid, alkaloid, minerals, catechins, caffeine, minerals, and other substances, which have a large molecular structure. Inherent smell of the plant raw material is influenced by the macromolecular structural groups. In a process of raw material flavoring, the fragrance may hardly cover the smell formed by the macromolecular structure of the raw material.
With reference to
The aerosol generating product is put into the inductor 470, and the inductor 470 is connected to the high-frequency power output from the high-frequency power supply 472, and the inductor 470 generates the high-frequency waves. Induction time is set to 10 s-180 s during induction.
Under the action of the high-frequency waves generated by the inductor 470, macromolecules in the plant raw material of the aerosol generating substrate 30 of the aerosol generating product absorb high-frequency wave energy and then are decomposed into micromolecular structures, such that smell brought by the raw material may be eliminated or reduced, and alcoholization of cigarette aroma is implemented.
The aerosol generating product provided with an electromagnetic susceptor is heated with an electromagnetic induction heater, and the aerosol generating product does not need to be inserted into a heating part of the heating apparatus for heating, such that no aerosol generating substrate 30 may be left on the heating part when the aerosol generating product is pulled out, which is conducive to cleaning of the heating apparatus. Meanwhile, when electromagnetic induction is used for heating, the electromagnetic susceptor generates heat uniformly, such that the aerosol generating substrate 30 is heated uniformly, and a better suction effect can be achieved.
To sum up, the aerosol generating product according to the present disclosure is an integrated porous and loose aerosol generating substrate. The crystal blocks and the plant fiber filaments coexist in the aerosol generating substrate. The gaps exist between the crystal blocks so as to allow the aerosol generated through heating to pass through. The gaps between the crystal blocks are not uniformly distributed in the space. The moisture content of the aerosol generating substrate is low, the moisture content of the aerosol generated through heating is low, and the temperature of the aerosol is low. The smoker is protected against mouth burning during suction without cooling. When the aerosol generating product is inserted into the heating part of the heating apparatus for heating, the insertion force is small, no specific insertion direction is required, the heat conduction effect is desirable, the temperature of the aerosol generated is conducive to suction of the smoker, the suction resistance is desirable, the desirable suction effect may be achieved, and meanwhile, the aerosol generating product may be adapted to the induction heating device for heating and suction.
Although the present disclosure is disclosed above, the present disclosure is not limited herein. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, so the protection scope of the present disclosure should be based on the scope defined by the claims.
