This application is a national phase entry under 35 U.S.C. § 371 of International Patent Application PCT/KR2016/003246, filed Mar. 30, 2016, designating the United States of America and published as International Patent Publication WO 2016/159648 A1 on Oct. 6, 2016, which claims the benefit under Article 8 of the Patent Cooperation Treaty to Korean Patent Application Serial Nos. 10-2015-0045122 and 10-2015-0045125, both filed Mar. 31, 2015.
Example embodiments relate to a method and apparatus for manufacturing a flavor capsule of a cigarette and, more particularly, to a method and apparatus for manufacturing a flavor capsule of a cigarette that may allow a membrane to be desirably bound to a flavored liquid.
In general, to manufacture cigarettes, various types of leaf tobacco are blended and processed to provide desired flavors and tastes to the cigarettes. The processed leaf tobacco is cut and folded to produce a cut tobacco leaf, and the cut tobacco leaf is then rolled with a cigarette paper to produce a filter-free cigarette. As necessary, a filter may be attached to such a filter-free cigarette.
The cigarette paper may be made with, for example, flax, wood pulp, and the like, and a need to be produced to maintain a burning quality and a taste of a cigarette while the cigarette is being smoked. The cigarette filter may include activated carbon, flavoring substances, etc. The cigarette filter may be embodied as a mono-filter or a multi-filter, and wrapped with a cigarette filter wrapping paper. The cut tobacco leaf and the cigarette filter are connected through a tipping paper that includes fine holes.
The cigarette filter may include a flavor capsule containing therein a flavor or incense. Thus, a user may taste the flavor, for example, a menthol flavor, when the flavor capsule is torn during smoking. Here, strength of the flavor capsule is important. For example, the flavor capsule may need to be torn based on a degree of an external force applied by the user during smoking, while also not being torn when the external force is not applied. Thus, there is a desire for a development of a method and apparatus for manufacturing a flavor capsule having a desirable strength.
Example embodiments provide a method and apparatus for manufacturing a flavor capsule of a cigarette that may improve efficiency in a process of manufacturing the flavor capsule by manufacturing a membrane and manufacturing the flavor capsule through a series of processes, and may manufacture the membrane to be desirably bound to a flavored liquid, thereby preventing the flavor capsule from being randomly torn to achieve stability and provide a user with reliability by tearing the flavor capsule only when an external force is applied by the user.
Example embodiments also provide a method and apparatus for manufacturing a flavor capsule of a cigarette that may have a dual discharge structure in which a flavored liquid and a membrane are discharged through respective discharge paths and, thus, an initial form of the flavor capsule is formed when the flavored liquid and the membrane are discharged through the respective discharge paths, thereby improving efficiency in a process of manufacturing the flavor capsule.

Through such a series of processes of manufacturing the membrane and manufacturing the flavor capsule, efficiency in the method of manufacturing the flavor capsule may be improved, and also the flavor capsule may be manufactured to allow the membrane to be desirably bound to the flavored liquid.

Hereinafter, example embodiments will be described in detail with reference to the accompanying drawings, wherein like reference numerals refer to like elements throughout. The following description relates to one aspect among various aspects of the present disclosure, and it constitutes a portion of the detailed description of the present disclosure.
In the description of the example embodiments, detailed description of well-known related structures or functions will be omitted when it is deemed that such description will cause ambiguous interpretation of the present disclosure.
Referring to
Through such a configuration described in the foregoing, a user may taste a flavored liquid contained in the flavor capsule 30 by having the flavor capsule 30 torn when the user smokes the cigarette 1.
For example, in a case of the cigarette 1 in which the flavor capsule 30 including a flavored liquid of menthol is embedded in the filter portion 20, the user may smoke the cigarette 1 while tasting a flavor of menthol by having the flavor capsule 30 torn when the user uses the cigarette 1.
The flavor capsule 30 may need to be torn or burst, based on the strength of an external force applied when tearing or bursting the flavor capsule 30, and needs to not be randomly torn or burst when the external force is not applied. The flavor capsule 30 includes a flavored liquid and a membrane wrapping the flavored liquid, and the strength of the membrane wrapping the flavored liquid may also be important to prevent such an unintentional tearing or burst. Hereinafter, a method and apparatus for manufacturing a flavor capsule will be described in greater detail with reference to the accompanying drawings.
Referring to
Through such a configuration described in the foregoing, a reliable flavor capsule may be manufactured, and also efficiency in a manufacturing process may be improved.
Referring to
In the weighing step S110, a precise weighing system configured to precisely weigh the amount of each of the substances may be used.
In the membrane forming step S120, the membrane 111 may be formed by the membrane manufacturer. Although not illustrated, the membrane manufacturer may include a membrane manufacturing container, a hot water boiler connected to the membrane manufacturing container through a connection line and configured to provide hot water to the membrane manufacturing container by heating up water, and a paddle configured to evenly mix the hot water and the substances in the membrane manufacturing container.
The substances included in the membrane 111 to be weighed in the weighing step S110 may include agar, pectin, sodium alginate, and glycerin as a plasticizer.
In a combination of the substances, the agar may play a role in hardening based on a temperature such that an initial form or shape of the flavor capsule 101 is formed at an initial stage of forming or molding. The pectin may act as an intermediate modifier between the agar and the sodium alginate and act on a degree of the hardening of the agar and on a calcium ion bonding of the sodium alginate, such that the initial form of the flavor capsule 101 is formed, and contributes to improving stability and moisture absorption or hygroscopicity and to forming the membrane 111.
The sodium alginate may be hardened by a calcium ion, and adjust strength of the flavor capsule 101 and form the membrane 111, and also improve hygroscopic stability by such an ionic hardening.
The glycerin may function as a plasticizer, improve formability or moldability of the flavor capsule 101, and provide elasticity to the flavor capsule 101. As an amount of the glycerin increases, the hygroscopic stability may deteriorate over the long term because the glycerin itself is highly hygroscopic, although the elasticity of the flavor capsule 101 increases. Conversely, as an amount of the glycerin decreases, the elasticity of the flavor capsule 101 may be reduced, and thus the flavor capsule 101 may be readily broken by an external factor. Therefore, an appropriate amount of the glycerin may need to be mixed.
Table 1 below illustrates weight percentages of the substances described in the foregoing.
In a case in which distilled water has a weight percentage of 90% (5% corrected), a weight percentage of the agar may be 1.5% to 3.5%, a weight percentage of the glycerin may be 2.0% to 10.0%, a weight percentage of the pectin may be 1% to 3%, and a weight percentage of the sodium alginate may be 0.2% to 0.7%.
In the membrane forming step S120, hot water heated to be 85° C. to 100° C., or more desirably 88° C., by the hot water boiler that may be supplied to the membrane manufacturing container, and then the agar may be injected to be dissolved in the hot water. Here, the agar may need to be injected gradually or slowly because the agar tends to be massed or lumped and not to be untangled or released when being injected all at once, and a mixer may be used to untangle the agar in the hot water. When the agar is injected, the paddle disposed in the membrane manufacturing container may operate at, for example, 90 revolutions per minute (rpm), and a temperature of the membrane manufacturing container may be monitored when the paddle operates.
For example, when the temperature of the membrane manufacturing container decreases to, for example, 85° C., the glycerin may be injected into the hot water in which the agar is dissolved. When the temperature of the membrane manufacturing container decreases to 83° C., the pectin may then be injected into the hot water to be dissolved therein. When the temperature of the membrane manufacturing container decreases to, for example, 78° C., after a predetermined period of time, for example, 10 minutes, elapses after the pectin is injected, the sodium alginate may be injected into the hot water and dissolved therein. As illustrated in Table 1 above, colorings such as the Blue No. 1 or the Red No. 40 may be injected into the hot water to manufacture the membrane 111.
Additionally, there are numerous factors that may cause a change in the viscosity of the membrane 111.
For example, when weighing the membrane 111, the viscosity may increase in response to an increase in a content of a substance included in the membrane 111 or decrease in response to a decrease in the content of the substance. In addition, there is a titrated dissolution temperature for a substance included in the membrane 111. Thus, when the substance is dissolved at a temperature lower than the titrated dissolution temperature, the substance may not be completely dissolved. Conversely, when the substance is dissolved at a temperature greater than the titrated dissolution temperature, a polymer structure may be broken and the viscosity may decrease, and thus the hygroscopic stability may not be desirable. In addition, when a temperature of the membrane manufacturing container is not maintained to be constant, the viscosity may change.
In a case of the membrane 111 with a low viscosity, a pulsation may be generated in a pump or stability of the flavor capsule 101 may deteriorate due to such factors described in the foregoing. Conversely, in a case of the membrane 111 with a high viscosity, the viscosity may change relatively severely with time, and thus formability and productivity may deteriorate. Thus, when the viscosity of the membrane 111 is out of the set range, it may be necessary to dispose of the whole quantity and newly manufacture the membrane 111 that satisfies a viscosity standard, and thus weighing an amount of a substance included in the membrane 111 and adjusting a titrated temperature when dissolving the substance may need to be precisely controlled.
The membrane transferring step S140 is performed to transfer the membrane 111 of which the viscosity is measured to the membrane tank 110 provided in the flavor capsule manufacturing apparatus 100.
When the membrane 111, manufactured in the membrane manufacturing step S100, is transferred to the membrane tank 110 of the flavor capsule manufacturing apparatus 100, the flavor capsule 101 may be manufactured in the flavor capsule manufacturing apparatus 100. Hereinafter, the flavor capsule manufacturing apparatus 100 will be described first in detail, and the capsule manufacturing step S200 will then be described in detail.
Referring to
The membrane tank 110 stores the membrane 111 manufactured in the membrane manufacturing step S100, and includes a rotating paddle 115 to maintain a dissolved and uniform state of the membrane 111. The membrane tank 110 is connected to the nozzle 140 through the membrane supply line 117, and thus the membrane 111 in the membrane tank 110 may be supplied to the nozzle 140. In the membrane supply line 117, a gear pump 118 is provided to supply the membrane 111 and opens the membrane tank 110 to smoothly transfer the membrane 111.
As illustrated in
The nozzle 140 forms the initial form of the flavor capsule 101, and discharges the membrane 111 flowing in the nozzle 140 to wrap the flavored liquid 121 to form the initial form of the flavor capsule 101.
As illustrated in
The nozzle 140 includes a nozzle body 141 forming a basic appearance thereof, a flavored liquid discharge line 143 formed along a center of the nozzle body 141 and configured to form a path through which the flavored liquid 121 is to be discharged, and a membrane discharge line 145 formed in the nozzle body 141 to be disposed in an outer side of the flavored liquid discharge line 143 and configured to form a path through which the membrane 111 is to be discharged.
The nozzle body 141 has a cylindrical shape as a whole, and a lower end portion thereof may become smaller in diameter downward toward the bottom. However, a shape of the nozzle body 141 is not limited to the example shape described in the foregoing.
As illustrated in
Also, as illustrated in
Thus, the flavored liquid 121 and the membrane 111 are discharged simultaneously through the jet 142 of the flavored liquid discharge line 143 and the jet of the membrane discharge line 145, respectively. Here, the membrane 111 wraps the outer surface of the flavored liquid 121 in an area of the jet 142, thereby forming the initial form of the flavor capsule 101 as illustrated in
In addition, the nozzle 140 may be designed based on a size of the flavor capsule 101.
As illustrated in Table 2 above, a size of the flavor capsule 101 and a structure of the nozzle 140 may change based on a type of the cigarette 1. That is, an inner diameter and an outer diameter of the nozzle body 141 forming the flavored liquid discharge line 143 may be determined based on the size of the flavor capsule 101. As illustrated in Table 2, in a case in which a diameter of the flavor capsule 101 is 2.1 mm to 4.7 mm, the inner diameter and the outer diameter of the nozzle body 141 may be 0.5 mm to 1.8 mm and 2.0 mm to 4.7 mm, respectively. It may be desirable that the inner diameter is 20% to 40% of the diameter of the flavor capsule 101, and a ratio of the inner diameter to the outer diameter may be two and one half to five (2.5:5). In addition, a thickness of the membrane 111 may be 0.5 mm to 0.8 mm.
For example, as illustrated, in a case in which the cigarette 1 is of a first type, for example, a super-slim type, the diameter of the flavor capsule 101 may be 2.8 mm to 3.0 mm, and the outer diameter and the inner diameter of the nozzle 140 may be 3.0 mm and 0.8 mm, respectively. In addition, a thickness of the membrane 111 immediately after forming may be 0.68 mm to 0.72 mm.
As described, the nozzle 140 may be designed to have an outer diameter and an inner diameter that are optimized based on a size of the flavor capsule 101, and a size of the membrane discharge line 145 may also be designed such that the membrane 111 has an optimized thickness.
The initial form of the flavor capsule 101 that is discharged by the nozzle 140 is transferred along the flavor capsule transfer line 190. Here, the MCT solution 131 flows along the flavor capsule transfer line 190, and thus the flavor capsule 101 is transferred toward the capsule storage 180 while being cooled along the flow of the MCT solution 131. That is, the MCT solution 131 forms such a flow, and the flavor capsule 101 is transferred along the formed flow.
As described above, the MCT solution 131 is supplied by the MCT tank 130. The MCT tank 130 and an upper end portion of the flavor capsule transfer line 190, which is adjacent to the nozzle 140, are connected through the MCT supply line 137 such that the MCT solution 131 is supplied to an inlet portion of the flavor capsule transfer line 190, which is a portion to which the flavor capsule 101 is discharged from the nozzle 140. Through such a structure, the MCT solution 131, or the coolant, may directly affect the flavor capsule 101 that is discharged from the nozzle 140, and thus the flavor capsule 101 may be cooled. Thus, surface bonding of the membrane 111 to the flavored liquid 121 may be more firmly performed.
In addition, the flavor capsule 101 and the MCT solution 131 that are transferred through the flavor capsule transfer line 190 are separated by a capsule separator 170, instead of being transferred immediately to the capsule storage 180 and, thus, the flavor capsule 101 is then transferred to the capsule storage 180 and the MCT solution 131 is transferred back to the MCT tank 130.
As illustrated in
The separation plate 173 is tilted downward in a direction of the capsule storage 180 such that the flavor capsule 101 transferred through the flavor capsule transfer line 190 is dropped into the capsule storage 180. Here, the MCT solution 131 transferring the flavor capsule 101 may also be dropped together with the flavor capsule 101. However, according to an example embodiment, due to the separation plate 173 being provided so as to have permeability, the MCT solution 131 may be dropped into the MCT storage tank 171.
Referring to
Hereinafter, the capsule manufacturing step S200 to be performed by the flavor capsule manufacturing apparatus 100 will be described in detail.
Referring back to
In the defoaming step S210, the membrane 111 manufactured in the membrane manufacturing step S100 is injected into a defoaming tank and air bubbles are defoamed from the membrane 111 by a defoamer. The defoaming step S210 may be performed in a vacuum for approximately 40 minutes. Here, it is obvious that the defoaming step may be performed on the flavored liquid 121 stored in the flavored liquid tank 120.
In the supplying step S220, the flavored liquid 121, the membrane 111, and the MCT solution 131 are supplied. Here, a steady velocity may change in an order of the flavored liquid 121, the membrane 111, and the MCT solution 131, starting from the flavored liquid 121. Using the respective pumps 118, 128, and 138, a supply speed of each of the membrane 111, the flavored liquid 121, and the MCT solution 131 may be set to be high, and then the membrane 111, the flavored liquid 121, and the MCT solution 131 may be supplied in the sequential order described in the foregoing. The supplying step may be performed in the sequential order to prevent generation of air bubbles.
In the capsule forming step S230, the flavored liquid 121 supplied from the flavored liquid tank 120 by the nozzle 140 is wrapped with the membrane 111 supplied from the membrane tank 110, and thus the flavor capsule 101 of the initial form is discharged from the nozzle 140.
That is, the flavored liquid 121 is wrapped with the membrane 111 when the flavored liquid 121 and the membrane 111 are discharged through jet portions after passing through respective paths of the nozzle 140, and thus the flavor capsule 101 of the initial form may be discharged.
In the capsule transferring step S240, the flavor capsule 101 discharged from the nozzle 140 is transferred toward the capsule storage 180 using the flow of the MCT solution 131 that is formed along the flavor capsule transfer line 190. Here, the MCT solution 131 cools the flavor capsule 101 such that the membrane 111 is more firmly bound to the flavored liquid 121.
Subsequently, the flavor capsule 101 and the MCT solution 131 are separated from each other by the capsule separator 170 as described above, and the separated flavor capsule 101 is transferred to the capsule storage 180 and temporarily stored therein.
In the hardening step S300, the flavor capsule 101 manufactured in the capsule manufacturing step S200 is first hardened. Here, the hardening is performed using a prepared ethanol (EtOH) solution. The prepared EtOH solution may be 70% to 100%, and a ratio of the prepared EtOH solution to the flavor capsule 101 may be one to one (1:1) to one to two (1:2), or more desirably, one to one and one half (1:1.5). However, the ratio is not limited to the example ratio described in the foregoing.
In the drying step S400, the hardened flavor capsule 101 is dried by a dryer. The drying of the flavor capsule 101 is performed at a set temperature, humidity, air flow, or rotation speed.
In the additional hardening step S500, the flavor capsule 101 is additionally hardened to prevent moisture absorption of the dried flavor capsule 101. A prepared EtOH solution used in this step as a hardening agent may be prepared by mixing ethanol and distilled water at a ratio of four to six (4:6) to seven to three (7:3). The distilled water may include 0.5% to 1.5% calcium chloride. For example, based on such a mixing ratio, a solution prepared by mixing 10 to 14 kilograms (kg) of ethanol, 7.92 kg of distilled water, and 0.08 kg of calcium chloride (or 1% calcium chloride) may be used for 10 kg of the flavor capsule 101 to be additionally hardened. Such an additional hardening may be performed to prevent the flavor capsule 101 from absorbing moisture.
In the cleaning step S600, the additionally hardened flavor capsule 101 is cleaned by a stirring cleaner. Here, 90% to 98% ethanol may be used as a cleaning solution, but a concentration of the ethanol is not limited thereto.
The flavor capsule 101 cleaned in the cleaning step S600 is dried by a dryer such as an electric dryer for a set period of time, transferred to a drying chamber with a temperature of 22° C. and humidity of 45%±5%, and then balanced and stored in a drying plate.
In addition, in a sorting step, among the flavor capsule 101, a flavor capsule that satisfies a standard is first sorted by a size sorter, and then a faulty flavor capsule is sorted out by a naked-eye sorter.
In the packing step S700 after the sorting is completed, the flavor capsule 101 that is normal is packed.
Hereinafter, a viscosity and a temperature of the membrane 111 will be described in greater detail.
As described above, the viscosity of the membrane 111 may be important when manufacturing the flavor capsule 101 by wrapping the flavored liquid 121 with the membrane 111. Thus, it is required to maintain a viscosity of the membrane 111 at a time of manufacturing the membrane 111, a temperature of the membrane tank 110, and a temperature of the membrane supply line 117 to maintain an appropriate viscosity of the membrane 111. In addition, it is also required that the coolant, for example, the MCT solution 131 as described herein, needs to be maintained in a set range.
Although not illustrated, the membrane 111 is manufactured by a membrane manufacturer. Here, the viscosity of the membrane 111 is maintained to be 300 cps to 700 cps, the temperature of the membrane tank 110 is maintained to be 55° C. to 75° C., the temperature of the membrane supply line 117 and the nozzle 140 is maintained to be 55° C. to 75° C., and the temperature of the MCT solution 131 is maintained to be 12° C. to 18° C. Thus, the viscosity of the membrane 111 may be maintained.
The viscosity of the membrane 111 at a time of manufacturing the membrane 111 is more desirably 500 cps to 650 cps, and a viscosity of the membrane 111 discharged from a tank of the membrane manufacturer is 400 cps to 550 cps. Here, the temperature of the membrane tank 110 is maintained to be 60° C. to 65° C., and the temperature of the membrane supply line 117 and the nozzle 140 is maintained to be 60° C. to 70° C.
As described above, the membrane 111 and the flavor capsule 101 are manufactured through a series of processes, and thus efficiency in the process of manufacturing the flavor capsule 101 may be improved. In addition, the flavor capsule 101 may be manufactured with the membrane 111 being appropriately bound to the flavored liquid 121 and, thus, a tearing or a burst of the flavor capsule 101 may be prevented to achieve stability. In addition, the flavor capsule 101 may be torn by an external force applied by a user, and thus provide the user with reliability.
In addition, a dual discharge structure in which the flavored liquid 121 and the membrane 111 are discharged through respective discharge paths may be provided and, thus, an initial form of the flavor capsule 101 may be obtained when the flavored liquid 121 and the membrane 111 are discharged through the respective discharge paths. Thus, the efficiency in the method of manufacturing the flavor capsule 101 may be improved.
In addition, in a process of manufacturing and transferring the membrane 111, a viscosity and a temperature of the membrane 111 may be maintained and, thus, production stability and formability of the flavor capsule 101 may be secured.
Further, the membrane discharge line may be provided as a plurality of membrane discharge lines disposed on the outer side of the flavored liquid discharge line, but not limited thereto. The membrane discharge lines may be provided to have a cross section of a circular band shape in the outer side of the flavored liquid discharge line, to discharge the membrane.
Although a few example embodiments have been shown and described, the present disclosure is not limited to the described example embodiments. Instead, it would be appreciated by those skilled in the art that changes may be made to these example embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
