Many liquids such as wine and distilled spirits, among others, require an extensive amount of time to age until the liquid has a suitable taste. In many cases, these liquids along with fruit juice, oils, and so forth require additives to enhance flavor, prolong shelf life, and preserve the liquid. Both the extensive amount of time to age and the addition of additives to the liquid may have detrimental effects in terms of production costs and, in some cases, health side effects to the consumer. For instance, additives may be added to a liquid to kill extraneous bacteria that, in some instances, form harmful microscopic noxious vaporous gases when ingested and can cause severe discomfort. Therefore, methods, devices, and systems to reduce the time required to age a liquid and reduce the addition of additives by breaking down the structure of the additives is needed.
The detailed description is set forth with reference to the accompanying figures. In the figures, the left-most digit(s) of a reference number identifies the figure in which the reference number first appears. The use of the same reference numbers in different figures indicates similar or identical items or features.
This disclosure describes methods, devices, and systems for altering a liquid. In some implementations, the liquid may include wine (e.g., red wine, white wine, rosé, etc.), fortified wine, liquor (e.g., scotch whisky, bourbon whiskey, tequila, vodka, gin, rum, etc.), liqueur, fruit juice (e.g., orange juice, apple juice, grape juice, pineapple juice, or combinations thereof), coffee, tea, oil (e.g., olive oil, peanut oil, sesame oil, or other plant-based oils), vinegar (e.g., balsamic vinegar, cider vinegar, malt vinegar, etc.), herb extracts, honey, molasses, dairy products (e.g., milk, cream, etc.), or a combination thereof. The liquid may contain any number of compounds or additives. For instance, the liquid may contain esters, tannins, pseudo tannins (e.g., gallic acid, flavan-3-ols, chlorogenic acid, ipecacuanhic acid), polycyclic aromatic hydrocarbons, sulfites, sulfur dioxide, other dissolved or undissolved gases, tartaric acid, malic acid, phenols, polyphenols, sugars, anthocyanins, flavonoids (e.g., quercetin), enzymes, preservatives (e.g., benzoic acid, sodium benzoate, sorbic acid, sodium sorbate, citric acid, ascorbic acid, tocopherol, lactic acid, etc.) and the like. One of ordinary skill in the art will understand the vast number of compounds that may be present in a liquid such as those listed above. In addition, the methods, devices, and systems described herein can be used in connection with liquids with varying viscosities and/or temperatures.
In some implementations, the disclosure describes methods and devices for altering the molecular structure of a small batch (e.g., a bottle or multiple bottles holding from about 0.184 liters to about 18 liters of liquid, or a container or multiple containers holding from about 3 ounces to about 26 ounces of liquid). In some implementations, the method can include placing one or more transducers (i.e., ultrasonic transducers) within a proximity of and in acoustic communication with the small batch of liquid. In some implementations, the transducer may be coupled to a water bath holding the liquid. The transducers can accept electrical energy from a generator designed to work with the transducer and the loaded environment (e.g., liquid coupling medium, pad, bladder, bottle, etc.) to produce ultrasonic excursions or ultrasonic frequencies. In some implementations, the amount of electrical energy supplied to the transducers may be from about 500 watts to about 1,500 watts or from about 600 watts to about 1,000 watts.
In some implementations, the amount of ultrasonic energy produced by the transducers may be adjusted based on characteristics of the liquid. These characteristics may include viscosity, type, number of identified compounds, temperature, etc. The ultrasonic frequency produced by the transducer may be above a threshold and may create cavitations (i.e., vapor cavities) in the liquid. The vapor cavities can be formed when the ultrasonic energy breaks down compounds and/or molecules in the liquid (such as those described above), which can create and release vaporous gases. These vaporous gases can agglomerate into cavitations, which can be nanometer sized. In some implementations, the cavitations produced by the ultrasonic energy may enhance flavor by breaking down compounds or cells not released during normal processing of the liquid and/or prolong stability of the liquid. By way of example, the methods, devices, and systems described herein may increase the shelf-life of wine by 10 or more days after the bottle is opened. In some implementations, modification of protein structures within the liquid can occur, which may improve a taste, aroma, stability, and color of a liquid. In some implementations, using the method described herein may allow for fewer preservatives to be used to accomplish the purpose of extending shelf life. In some implementations, the pH of the liquid may be reduced. Altering the liquid as described herein may improve sensory, digestive, or medicinal results of the liquid.
For example, using wine as a consumable liquid, a 750 ml bottle of Washington Cabernet Sauvignon wine can be processed by the methods and devices disclosed herein for approximately 20 minutes at 40 kHz. Before processing, the pH of the wine was 3.58. After processing, the pH was 3.52 and the taste of the wine noticeably improved.
In another example, using whiskey as a consumable liquid, a 50 gallon Washington Rye Whiskey that would normally be aged 2-3 years longer than when the sample was taken was processed using a 1,050 watt continuous flow system (described in more detail below) at 20 kHz at a flow rate of 10 gallons per minute. Before processing, the pH of the whiskey was 4.19. After processing the pH was 4.06.
The time period for which liquid can be exposed to ultrasonic energy to reach the results described herein may differ depending on the type, volume, and/or other characteristic (e.g., viscosity, temperature, etc.) of liquid being processed. For example, a bottle of wine may be processed for 5 to 30 minutes, or from 7 to 10 minutes, using the methods described herein.
The methods, devices, and systems described herein may not eliminate or add to what was originally in the liquid. In some implementations, the methods, devices, and systems may permanently alter a molecular configuration of the liquid.
This disclosure also describes methods and systems for altering the molecular structure of a liquid with a continuous flow (i.e., large batch) system. In some implementations, the system may include an exposure container having one or more transducers in acoustic communication with the exposure container. The liquid may be pumped through the exposure container by a pump, such as for example a variable speed pump, from a source container to a finishing or target container. In some implementations, the rate of flow of the liquid through the exposure container may be varied by, for example, a flow valve. In other implementations, the liquid may be moved through the system by an apparatus or method other than a pump. For instance, the system may include a vacuum such that the liquid is pulled through the exposure container. In another example, gravity may be used to move the liquid through the described system. Finally, any combination of the described pump, vacuum and/or gravity can be used in combination.
As mentioned above, the one or more transducers may produce cavitations in the liquid as it flows through the exposure container. The one or more transducers may break down and release vaporous gases, or in some cases liquefy, and agglomerate the gases as mentioned above. In some implementations, the one or more transducers may be angled or aimed in a direction that is deviated from the directional flow of the liquid, which may intensify the break down and release of vaporous gases or alter the cavitations.
The cavitations may exhibit a temperature and pressure that is greater than the temperature and pressure of the surrounding liquid. The frequency at which the transducers produce ultrasonic energy may be varied. Additionally, the size of the cavitations may change based on the ultrasonic frequency, and the temperature and pressure within each of the cavitations may also change based on the ultrasonic frequency. For instance, at greater frequencies of ultrasonic energy the pressure within each of the cavitations may be greater and/or small cavitations may occur. However, as frequency increases there may be fewer cavitations. Additionally, lower frequencies of ultrasonic energy produced by the transducers may result in larger cavitations with a lower internal pressure. In some cases, lower ultrasonic frequencies with a greater wavelength and larger cavitation bubble may not exceed a first threshold of energy needed to create the optimum cavitations, yet cavitations may also be absent at higher frequencies above a second threshold. In some cases, lower frequencies with longer wavelengths may leave areas of the liquid unprocessed.
In some implementations, the compounds and molecules mentioned above may be captured within or upon the cavitations. In some instances, the pressure and temperature associated with the cavitations may fragment or otherwise alter the compounds and molecules. In some instances, the fragmented or altered compounds may release flavors that would normally be contained within their molecular structure.
In other implementations, the continuous flow system may include a degassing container, especially if the system is processed under a pressure. The degassing container may be described as a degassing mechanism, which can be, for example, a degassing opening in the exposure container or other components of the system. In some instances, the degassing container may allow the release of gases (sulfur dioxide, nitrogen, etc.) introduced to preserve the liquid. In some applications, the degassing mechanism may or may not contain additional ultrasonic transducers and be energized at a frequency above the threshold of cavitation at the same, or different, frequencies as the flow through processing chamber. In other implementations, the continuous flow system may include other containers that may introduce flavors or other additives to the liquid either prior to the exposure container or after the exposure container. For instance, the system may include a container having wood chips, which may add specific flavor characteristics to the liquid.
In another implementation, one or more transducers may be placed proximate to the container holding the liquid. In some implementations, the transducers may be hung within the container and immersed in the liquid. In other implementations, the transducers may be arranged in one or more arrays that may maximize the effects of the ultrasonic energy on the liquid.
The implementations described above may significantly reduce an amount of wait time a liquid may generally require to reach its peak or optimized flavor. For instance, wine or whiskey may require an extensive amount of wait time in wooden casks or barrels to mature (i.e., breakdown and release flavor-preferred compounds or molecules) to acquire a desired flavor characteristic. However, the controlled cavitations produced by the ultrasonic energy of the transducer in the methods, devices, and systems disclosed herein may greatly accelerate this maturation process. Furthermore, the methods, devices, and systems described herein may enhance the desirable characteristics (e.g., flavor, smell, etc.) of the liquid.
In the implementations described herein (i.e., small batch processing or continuous flow through processing) the transducer(s) may be programmed to produce a frequency from about 10 kHz to about 120 kHz, or from about 20 kHz to about 50 kHz, or from about 30 kHz to about 45 kHz, or from about 40 kHz to about 42 kHz. In some implementations, as frequency increases, fewer cavitations may be available and may require more energy to create cavitations.
In some embodiments, the devices described in the present disclosure can be used in the creation of liposomal liquid compounds. For example, plant-based components may be combined with lecithin (fatty substance occurring in animal and plant tissues) and water or other effective liquids. These components may be mixed together and exposed to the frequencies described herein, such as ultrasonic frequencies. This sonication may create a stable fat-encapsulated composition, which may be described as a micro-nutrient. The micro-nutrient may be ingested and may increase the uptake and bioavailability of the micro-nutrient for human and animal treatments.
Additionally, the devices described in the present disclosure can be used to extract compounds from plant-based tissues. For example, a plant-based material may be added to one or more liquid surfactants in the devices described herein. Ultrasonic energy can be directed toward the plant-based material, and heat may be applied. This process may cause materials within the plant-based tissue to breakdown or otherwise be altered. Certain compounds in the plant-based tissue may be released from the plant-based tissue, or may be retained within the plant-based tissue. Use of ultrasonic energy as described herein may increase the availability of active ingredients in the plant-based tissue, or cause those active ingredients to be more readily removed from the plant-based tissue. The availability of the active ingredient may be increased by 60% or more than availability of the active ingredient without use of ultrasonic energy.

The overview is provided for the reader's convenience and is not intended to limit the scope of the implementations or claims, nor the proceeding sections.
In small batch treatment of liquids, time of exposure to cavitations may be critical due to potential heat buildup. In some implementations, the small batch environments described below and shown in
Turning now to the figures,
In some implementations, the frequency of the transducer 104 may be fixed for a period of time. In other implementations, the frequency may step up or step down over a period of time, or otherwise be variable. Alternatively or additionally, the frequency of the transducer 104 may sweep (i.e., progressively vary) between different frequency ranges over a specific predetermined period of time. In some implementations, the frequency of the transducer 104 may be preset for specific liquids based on characteristics of the liquids. For instance, red wine may generally require a greater frequency (i.e., higher pressure associated with the cavitations) and/or a greater period of cavitation formation in order to optimize flavor characteristics, while white wine may require a lesser frequency or less processing time. In some implementations, the device may be configured to produce from about 10 kHz to about 120 kHz, from about 20 kHz to about 50 kHz, from about 30 kHz to about 45 kHz, or from about 40 kHz to about 42 kHz. In some implements, the ultrasonic energy may be turn off for some period of time, such as, for example, a millisecond. By doing so, undissolved and entrapped gasses may be released to and dispersed on the surface of the liquid. This burst of ultrasonic energy may also utilize the greater excursion phenomena of piezoelectric transducers when such a burst of energy is applied.
Using wine as an example consumable liquid, wine can be a very complex liquid comprised of over 250 identifiable compounds and over 160 esters. To reach the consumption readiness state, wine may go through a time consuming maturation and aging process that is characterized by a long-term interaction, or chemical reaction, of its many components. The interaction eventually reaches an optimum state (i.e., “peak bouquet”), after which the interaction results in a deterioration of flavor. Using the method of directing ultrasonic energy into the consumable liquid to generate cavitations with the device shown in
This disclosure is not intended to be limited to wine. The methods of producing cavitations, and the devices and systems disclosed herein, may be applied to other liquids such as but not limited to, orange juice. In such an application, many of the microscopic compounds that appear in wine also exist in orange juice. As mentioned above, many of the flavorful compounds captured within pulp and cells are not released through normal processing but may be released using the methods, devices, and systems described herein.
In some instances, ripening of fruits can be somewhat analogous to aging of wine. Once the fruit is fully ripened to a stage where it is flavorful, it can quickly pass through a period of peak bouquet and begin to deteriorate or ferment thereafter. Without preservatives, freezing, or running through a concentration process, the fruit can have a comparatively short shelf life or period of peak bouquet.
By subjecting the juice to ultrasonic energy to produce cavitations at or near the juice's peak bouquet, as in wine, the ultrasonic energy can break down and agglomerate the juice compounds, releasing and combining tartaric acids, malic acids, phenols, polyphenols, sugars, and vaporous gases, for example, that influence flavor. Modification of protein structures can occur, which may significantly benefit taste, aroma, stability, and/or color of the resultant juice. If preservatives are used, the ultrasonic energy may break down those preservatives into gases, which may be agglomerated in the cavitations, thereby minimizing the amount normally used to preserve the product.

Ultrasonic energy produced by the transducer 204 can readily be transmitted through the bladder 210, a liquid coupling medium that may surround the liquid-containing vessel, and the liquid-containing vessel itself to cause the cavitations within the liquid as described above. In some implementations, bladder 210 may conform to the bottom profile of the liquid-containing vessel being processed, thus minimizing air or high acoustic impedance barriers between the transducer 204 and the liquid being processed. The device 200 may provide superior transmission of ultrasonic energy while also minimizing heat buildup, which may occur in direct liquid coupling as described in
In some implementations, the housing 202 may be plastic, metal, or a combination thereof. In some implementations, the bladder 210 may comprise a flexible, thin membrane made of a polymer or similar material configured to hold a liquid. In some instances, the liquid within the bladder 210 may be degassed before being sealed in bladder 210 to avoid cavitations within the bladder 210 when the transducer 204 is in operation. In some implementations, the internal portion of the bladder 210 may also hold a liquid coupling medium as described above with reference to

In some implementations, the device 500 may further include a display 506 to display information such as an LCD display. In some instance, the display 506 may display information such as a countdown timer indicating a time remaining in the ultrasonic process, a current frequency being produced by the transducer, or other information.
In some implementations, device 500 may include one or more processors and memory which may store various modules, applications, programs, or other data. The memory may include instructions that, when executed by the one or more processors, cause the processors to perform the operations described herein for operation of device 500.
For instance, the device 500 may be configured with a network interface module coupled to an antenna to support both wired and wireless connection to various networks, such as cellular networks, radio, Wi-Fi networks, short range networks (e.g., Bluetooth), IR, and so forth. For example, the antenna may receive a wireless signal at the wireless unit from an auxiliary electronic device via a dedicated application, the signal comprising data which may be displayed on the display 506. The network interface may provide an ability to send and/or receive information about a particular liquid, along with other products and services related to the liquid, such as recommended food pairings, leisure activities, travel, and other related promotional offers.
The memory may include computer-readable storage media (“CRSM”), which may be any available physical media accessible by the processor to execute instructions stored on the memory. In one basic implementation, CRSM may include random access memory (“RAM”) and Flash memory. In other implementations, CRSM may include, but is not limited to, hard drives, floppy diskettes, optical disks, CD-ROMs, DVDs, read-only memories (ROMs), random access memories (RAMs), EPROMs, EEPROMs, flash memory, magnetic or optical cards, solid-state memory devices, or any other medium which can be used to store the desired information and which can be accessed by the processor.
Implementations may be provided as a computer program product including a non-transitory CRSM having stored thereon instructions (in compressed or uncompressed form) that may be used to program a computer (or other electronic device) to perform processes or methods described herein. Further, implementations may also be provided as a computer program product including a transitory machine-readable signal (in compressed or uncompressed form). Examples of machine-readable signals, whether modulated using a carrier or not, include, but are not limited to, signals that a computer system or machine hosting or running a computer program can be configured to access, including signals downloaded through the Internet or other networks. For example, distribution of software may be by an Internet download.
In some implementations, the memory may store a data capture module, a data storage module, and a data providing module (not shown). The modules may be stored together or in a distributed arrangement. In some implementations, the modules may represent services that may be performed using components that are provided in a distributed arrangement, such as by virtual machines running in a cloud computing environment.
Typically, in systems that utilize the continuous flow methodology for providing ultrasonic energy to a liquid, a large quantity of liquid may be processed. While the ultrasonic frequency produced by the transducer may or may not be constant, exposure time may be controlled by rate of flow of the liquid and backpressure within the processing container.
In some implementations, a continuous flow system may allow the use of a greater concentration of ultrasonic energy over a shorter exposure time and can be controlled by rate of flow. As an example, at 20 kHz power levels, as much as 2-10 watts per ml can safely be applied to certain wines at flow rates of 20 grams per minute. While this approach may allow a high concentration of ultrasonic energy, erosion of the transducer's surface and metal fatigue may become a minor cost factor. In some implementations, a degassing container or degassing portion of the exposure container may be employed after initial processing of the liquid. The degassing container may minimize or eliminate gases created during processing that could not be removed in the processing chamber. Those gases, if not removed, may be absorbed back into the treated liquid through agitation or otherwise.
As mentioned above, the presence of dissolved or undissolved gases in liquids may be detrimental to taste, preservation, and/or flavor of the liquid. Such gases can be added into the liquid by agitation, pumping, shaking, or even standing within natural or positive pressure atmospheric environments. In wine, for example, when inserting a cork into the bottle holding the wine, positive pressure may be created within the bottle. Some wine makers introduce nitrogen into the bottle for protection of the wine, but the nitrogen may be forced into the wine and, if not released, may affect flavor and/or aroma of the wine and may be absorbed by the human body upon consumption. Therefore, allowing wine to breathe before consumption can be practiced, but even allowing wine to breathe may release only a minimal amount of the nitrogen or other gases within the wine.

A pump 808 may also make up a component of system 800. In an embodiment, the pump 808 may be coupled to the first tube 806. The pump 808 may promote or otherwise cause flow of liquid from the first container 802 to the second container 804, or vice versa. The pump 808 may operate manually or electronically, and when electronically, may operate within a computing environment and/or wirelessly. The pump 808 may control the speed of the liquid traveling through system 800 during processing as described above. In some embodiments, the pump 808 may be disposed anywhere in system 800.
One or more transducers 810 may also make up a component of system 800. In an embodiment, the transducer 810 may be placed in acoustic communication with the second container 804. Acoustic communication can include being placed in proximity to the second container 804 such that when the transducer 810 is operative, the ultrasonic energy transmitted from the transducer 810 may travel at least partially into the second container 804 and is capable of interacting with liquid within the second container 804. The transducer 810 may be capable of producing an ultrasonic frequency that may be directed into liquid within the second container 804.
A third container 812 may also make up a component of system 800. In an embodiment, the third container 812 can be coupled to the second container 804 by a second tube 814. The second tube 814 can be of varying lengths and sizes to accommodate a variety of liquids or system configurations. By way of example, the second container 804 and the third container 812 may be in the same room, or may be situated in different rooms, buildings, or geographic locations. The second tube 814 may be of any length to couple the second container 804 and the third container 812 such that liquid may flow from the second container 804 to the third container 812, or vice versa. It is to be understood that while the example embodiment in

A pressure gauge 816 may also make up a component of system 800. In an embodiment, the pressure gauge 816 can be coupled to the first tube 806, the second tube 814, or to any other component of system 800. The pressure gauge 816 can measure the pressure within system 800, which can provide an operator or a computing environment with pressure-related information to be used to control and adjust the cavitation formation within system 800, as described above.
A flow valve 818 can also make up a component of system 800. In an embodiment, the flow valve 818 can be coupled to the first tube 806, the second tube 814, or to any other component of system 800. The flow valve 818 can allow a user or a computing environment to adjust pressure within system 800 or the components thereof by, for example, allowing more or less liquid to flow from the second container 804 to the third container 812. In some instances, an appropriate amount of backpressure may enhance results.
The positioning of the transducer 810 can vary. In some implementations, the transducer 810 may be positioned such that the radiating surface 822 of the transducer 810 faces the direction of flow of the liquid. The transducer 810 may be configured to produce ultrasonic energy on an exponential or stepped basis for purposes of creating maximum excursion and energy at the radiating surface 822. The transducer 810 may also be placed at some angle, for example a 90° angle from the direction of flow of the liquid. If placed at a 90° angle from the direction of flow, the ultrasonic energy may be bent or otherwise altered as liquid flows, which could attenuate the effectiveness of the cavitations. It should be understood that the present disclosure includes embodiments wherein the first container 802, second container 804, and third container 812 may be coupled to each other, directly or indirectly, and may make up the same or partially the same container.

In some implementations, systems 800, 900, 1000, and/or 1100 may include a temperature regulator such as a heating coil or cooling coil. The temperature regulator may alter the temperature of the liquid within the system and/or alter the viscosity of the liquid. In some instance, these alterations may enhance the effectiveness of the cavitations produced by the transducers as described above.

In the application of processing distilled spirits such as whiskies, cognac, and the full range of distilled alcoholic beverages, there may be fewer compounds to consider since many compounds have been removed in the distillation process of these spirits. After distillation, certain compounds that effect flavor can be added back into the liquid. At this stage, with flavoring added, the application of ultrasonic energy to generate cavitations can be applied to alter molecular structure, lower pH, enhance flavor, and reduce aging time.
Ultrasonic energy may be applied to distilled spirits immediately after distillation or within a few weeks after exposure to elements extracted from oak, thereby reducing the time necessary for aging. In such applications aging can be drastically reduced form years to minutes of exposure. If oak chips or other adjuncts are used rather than barrels, the introduction of ultrasonic energy to generate cavitations may further shorten this process.
Barrel aging can be a long-term process because of the time needed to dissolve the desirable flavors in oak barrels and then only to a certain depth, such as 6 to 8 mm of the barrel. Different oaks largely determine aging time and flavor. Surface area of barrels also affects aging time. Wood chips may provide greater surface area and more thorough penetration of the liquid. Because wood may attenuate sound, it can be necessary to increase the amount of ultrasonic energy using the methodologies described herein to achieve results.
In addition to distilled spirits, many plant extractions (liquids) offered for consumption contain additives that serve only to increase shelf life. Other additives may be added for flavor, but do not necessarily add nutritional value. Some consumers of these plant extractions can experience adverse reactions caused by these additives.
While the described methods, devices, and systems reduce, but may not eliminate additives, the additives may be rendered more effective by breaking down, agglomerating, liquefying, and rendering them in more intimate contact with the compounds they are intended to preserve.
Among the most common and effective of additives used to inhibit extraneous bacteria growth in wines is sulfite. Some countries and states require that sulfite be identified on the label of a bottle containing sulfite. Sulfite's effectiveness in inhibiting extraneous bacteria growth is largely dependent on the amount used. Large-scale wine producers, whose risks are high, may use a higher concentration of additives to avoid spoilage (a financial risk/benefit decision). The down side is the effect on the quality of the wine or end product. Some wine producers make and advertise that they do not use any added sulfite.
Sulfite does not improve taste, nor is it tasteless by itself. Many consumers complain of headaches attributed to sulfite and other additives. Although this has yet to be clinically isolated, there is a significant portion of the population that experiences this effect. Wines not containing sulfite additives usually garnish a higher retail price.
Adverse reaction to sulfite and other preservatives can be attributed to their presence in the form of microscopic vaporous gases throughout the liquid. If left in that state and consumed, those gases can enter the blood stream and be transported to the brain. This may cause headache (“hangover”), or perhaps other even more potentially serious physical effects. Some people are more sensitive than others and refuse to consume wine containing those additives.
The present disclosure embodies a means of permanently and effectively removing those undissolved and/or entrapped gases within the liquid without adversely affecting the preservative aspect to which they were applied or intended, breaking down, agglomerating, and altering molecular structures and releasing entrapped flavors. Equally important is the effect on protein structure and distribution that contribute to sensory improvement.
In some instances, re-processing a bottle of initially processed liquid after a period of time (e.g., 3 days, 5 days, 7 days, for example) may reinvigorate the liquid. This is helpful in a restaurant setting where a bottle of wine may be opened and corked for several days after an initial ultrasonic treatment. In these instances, an additional ultrasonic treatment may break down or allow oxygenated molecules to escape the opened bottle of wine to make the opened bottle of wine taste and/or smell better.
Cavitation bubble size may be defined by frequency. For purposes of removing gases, the operating frequency may not necessarily be sensitive. For purposes of agglomeration and determining molecular structure of the end product, frequency and energy level can become an important consideration.
As an example of proven effectiveness of the present disclosure, we employed the use of a Sulfite Testing Kit “Titrates for the Determination of Sulfite in Wine,” manufactured by CHEMetrics, Inc., Component Catalog NO: A-9610T.
Using a sample 5 gallon batch of a low cost commercially sold wine, achieving a base line indication of sulfite content, and then subjecting it to ultrasonic energy for 15 minutes, at frequencies within 3 kHz from nominal frequency of 40 kHz, we achieved a reading indicating a 39% reduction of sulfite content. There was also a noticeable improvement in the smoothness and taste of the wine attributed to the removal of entrapped gases, agglomeration, and overall change of molecular structure.
While this experiment was with wine, it should not be isolated thereto. This experiment is analogous to any liquid that contains additives such as sulfite that produce unwanted microscopic entrapped gases.
Much of the above addresses the effect of preservatives in wine and beverages that contain preservative additives. Many beverages do not contain added preservatives, yet the effect of subjecting those beverages to ultrasonic energy will yield a far superior tasting product. Olive oil, as an example, does not contain sulfite additives, but by subjecting this product to the methodologies described herein a marked improvement in flavor was noted. This was accompanied by a noticeable reduction in peroxide reading such that the sample tested, originally classified as category “Virgin,” was deemed to be equal to “Extra Virgin” after 20 minutes exposure in a batch processing system, operating at a nominal sweep frequency of 40 kHz.
Although the disclosure describes embodiments having specific structural features and/or methodological acts, it is to be understood that the claims are not necessarily limited to the specific features or acts described. Rather, the specific features and acts are merely illustrative of some embodiments that fall within the scope of the claims of the disclosure.
This application claims priority to U.S. Provisional Patent Appln. No. 62/054,206 filed Sep. 23, 2014, entitled “Method and Systems for Altering the Molecular Structure of Consumable Liquids,” the entirety of which is incorporated herein by reference.
