    HISTORY OF THE INVENTION
    [0001] Sparkling drinks are manufactured by dissolving carbon dioxide in a liquid, typically by pressurizing the liquid with carbon dioxide. When the pressure of the frothy drink is low, bubbles of carbon dioxide may form and exit the solution.
    [0002] Carbon dioxide is typically supplied as pressurized gas in pressurized tanks or cartridges. For example, carbonated water can be made through a refillable soda trap, or a disposable carbon dioxide cartridge. The soda trap can be filled with ice water and carbon dioxide can be added under pressure. Sparkling drinks produced in this way tend to be only slightly fizzy.
    [0003] Alternatively, carbonators or carbonation machines can be used. Carbonators range from domestic-scale machines, such as Sodastream ™, to large-scale carbonators. Carbonators pump water into a pressurized chamber, where it is combined with CO2 from pressurized tanks. Pressurized carbonated water can be mixed with flavorings, typically in the form of syrups.
    [0004] However, pressurized CO2 tanks are expensive to manufacture and require careful handling. Petition 870200019388, of 10/02/2020, page 10/36 transport of pressurized C02 tanks is complicated due to its high weight and high pressure. In addition, it is not allowed to send pressurized C02 tanks by air in aircraft In addition, refilling a pressurized C02 tank requires the tank to be taken to the service site, which is a burden.
    [0005] C02 can also be supplied by chemical reaction of, for example, sodium bicarbonate and citric acid. However, this method is impractical, since the chemical reaction results in other materials, such as salts, which can influence and degrade the flavor of the drink. Separating the liquid from the salt is complicated and makes this approach impractical.
    [0006] U.S. Patent No. 5,182,084, to Plester, describes a portable carbonator, which includes an embedded CO2 supply system operated in disposable gas generation cartridges. CO2 is generated by a chemical reaction between reagents, which carbonate and / or propel water. The system described in U.S. 5,182,084 is intended to maintain a constant gas pressure whenever carbonated water is removed. The carbonator disclosed in U.S. Document No. 5,182,084 is very complicated, involving numerous mechanical, stationary and mobile (dynamic) elements, as described, for example, in Figure 4.
    [0007] U.S. Patent No. 5,350,587, to Plester, describes a CO2 gas generator, which chemically generates the gas from a chemical reaction between two reagents contained within a common container. The generator aims to automatically supply gas, in order to maintain the pressure of the gas void space in constant reference in relation to a reference pressure. While claiming to provide a device that is easy to use by non-professional users, based on disposable gas generating units, in practice, the device according to that patent, as can be seen, for example, in Figures 3A-3L, involves highly complicated mechanical elements, including containers within containers, mechanical valves designed to control the disposition of gas and the release of reagents, etc.
    [0008] U.S. Patent No. 4,636,337, to Gupta, describes device and method for delivering CO2 gas to carbonated water. The device and method employ a gas generator using two chemically active reagents in the presence of water. The device teaches a bleed to maintain the pressure in the empty space at sufficiently high levels, while maintaining a continuous flow of CO2 through the carbonated liquid.
    [0009] U.S. Patent No. 5,192,513, to Stumphauzer, describes device and method for rapid carbonation of water using chemical reaction taking place in a pressure vessel, and transferring CO2 to a second pressure vessel. An object of the described device and method is to provide a simple, inexpensive and efficient process for generating CO2 and carbonating water quickly. However, the device, as described, for example, in Figure 1, is very complicated and includes a large number of parts, which takes it away from being simple.
    [0010] U.S. Patent No. 5,021,219, to Rudick, describes device and method for self-regulating the CO2 gas generator for the carbonation of liquids. The gas generator consists of two liquid chambers for containing liquid reagents, which, when chemically combined, react and produce the gas. Here, too, the devices described are complicated, include a large number of parts and do not operate with disposable reagent packs.
    [0011] British Patent No. 323102, to Blaxter, describes apparatus for carbonation, which pumps carbonated water together with carbon dioxide to a carbonation vessel, which is also supplied with de-aerated water to that vessel, and to a fuel pump. mixture, which supplies water and carbon dioxide to a carbonation vessel.
    [0012] International Patent Application Publication No.WO 94/10860, to Stumphauzer, describes device and method for the rapid carbonation of liquids. The device consists of two vessels connected together, in which gas is produced using carbon dioxide compound and water, which, when chemically reacts with the compound, produces gas. The device is very bulky and involves a large number of parts (valves, seals, springs, ducts and the like).
    [0013] International Patent Application Publication No.WO 2011/094677, to Novak, describes system, method and cartridge for liquid carbonation. Carbon dioxide can be supplied in a cartridge used to generate CO2 gas to be dissolved in the liquid.
    [0014] U.S. Patent Publication No. 2011/226343, to Novak et al., Describes system, method and cartridge for carbonating a precursor liquid to form a beverage. The system and method described by Novak et al. require the loading of zeolite with carbon dioxide by exposing the zeolite to a temperature of 550 ° C for a period of 5 hours in an oven and then immediately transferring the zeolite beads to a sealed metal container, flooding the container with carbon dioxide and pressurizing the container to 5-32 psig for 1 hour. During this process, the zeolite beads are charged with carbon dioxide, which can be released when exposed to water or other fluids, as well as water vapor and moisture. Correspondingly, the loaded zeolite must be packaged in a moisture-free installation and in moisture-resistant packaging. It can be appreciated that the above loading process makes the preparation of a cartridge for the preparation of a carbonated beverage relatively expensive. Another disadvantage of the above system and method is that the charged zeolite is highly sensitive to moisture and any interaction with moisture or fluids activates the release of carbon dioxide from the cartridge. Therefore, the shelf life of such cartridges is limited and requires careful handling to avoid mechanical damage to the sealed zeolite packaging in the cartridge. SUMMARY OF THE INVENTION

    [0028] In the following detailed description, numerous specific details are shown in order to provide a complete understanding of the invention. However, it will be understood by those skilled in the art that the present invention can be practiced without these specific details. In some cases, well-known methods, procedures and components have not been described in detail, so as not to obscure the present invention.
    [0029] Although modalities of the present invention are not limited in this regard, the words "plurality" and "one plurality", as used herein, can include "multiples" or "two (two) or more". The words "plurality" or "a plurality" can be used throughout the specification to describe two or more components, devices, elements, units, parameters or the like. Unless stated explicitly, the method modalities described here are not restricted to a particular order or sequence. In addition, some of the described method modalities or elements of them may occur or be carried out in the same time.
    [0030] The heating of compositions to a temperature that is higher than the thermal decomposition temperature of that composition, in order to decompose it, is well known. Similarly, heating compositions to a temperature that is higher than the phase transition temperature, in order to cause the composition to undergo phase transition, is well known. For example, heating a composition, which includes CO2, to a temperature that is higher than the thermal decomposition temperature, can decompose it and therefore can cause the decomposed material to release CO2. In many cases, such a process, which is known as calcination, or calcination reaction. For example, when limestone is calcined, the chemical reaction is expressed: CaCO3 -> CaO + CO2 (g)
    [0031] In other words, the calcination process decomposed limestone to formal lime (calcium oxide) and carbon dioxide. Well-known examples of calcination processes, mainly maintained on large scales (industrial scales) are designed to remove certain components unwanted effects of the composition. An example is the decomposition of hydrated minerals, as in the calcination of bauxite and plaster, to remove crystalline water. Another example is the decomposition of volatile matter contained in crude petroleum coke and yet another example is the removal of ammonium ions in the synthesis of zeolites.
    [0032] Many devices and methods for the carbonation of liquids are known. Some require complicated and bulky devices and multi-stage methods, even for the production of carbonated drink for personal use. Several known devices and methods describe the use of reagent pairs that, when chemically activated, release carbon dioxide, which can be used for carbonation of the liquid, to create the fizzy drink. Other devices and methods make use of pre-pressurized C02, which is contained in high pressure containers, from which the pre-pressurized C02 can be released into a container holding the drink in order to carbonate it. The use of pairs of reagents for the production of C02 requires means to keep the reagents separate from each other until the chemical reaction occurs, and in many devices known in the art complicated and bulky carbonation devices are required in order to control the carbonation process. The use of pressurized C02 containers is typically less complicated than the use of carbonation devices based on chemical reaction of reagent pairs, however, the handling of pressurized C02 containers is typically inconvenient and - with non-disposable containers, the burden of loading full containers from storage and empty ones back there.
    [0033] The inventor of the modalities of the invention, which are described here, below, found that the amount of CO2, which can be released from a relatively small amount of sodium bicarbonate, during the calcination process, is relatively large . For example, from a sodium bicarbonate tablet weighing 35 grams, when calcined at temperatures of around 60-200 degrees centigrade, C02 is released in an amount that is sufficient to carbonate water or similar liquid in the amount of 1, 5 liters, with a carbonation level of about 2 to 4 volumes, and a temperature of 2 to 15 degrees. This CO2 production ratio is very high, compared to other known methods. This allows to produce, according to a user's desire, an amount of CO2 that is sufficient for a 1 liter container, from a sodium bicarbonate tablet weighing about 25 g.
    [0034] Heating materials, such as sodium bicarbonate (NaHCO3) or other substances that include carbon dioxide (CO2), to which you refer hereinafter, as a CO2 vehicle, can release CO2 gas. For example, if sodium bicarbonate is heated, in solid form, in a closed vessel, to a temperature higher than the decomposition temperature, the following will apply: 2 NãHCOj (s) Na2C03 (s) + H2O (g ) + CO2 (g)
    [0035] The same applies, with the necessary changes, to sodium bicarbonate in other states and forms, such as in a dry or wet powder state or in a solution or emulsion state.
    [0036] According to the modalities of the present invention, sparkling drinks, which are also referred to as carbonated drinks, can be produced by heating the CO2 vehicle and by dissolving the CO2 gas released in water or in another liquid, such as juice or wine.
    [0037] At temperatures above 70 ° C (degrees Celsius), sodium bicarbonate gradually decomposes into sodium carbonate, water and carbon dioxide. The conversion is fast at 2002C. For example, by heating 8 grams of baking soda to 180 degrees Celsius, 1.5 liters of CO2 gas can be produced. To achieve a high level of carbonation in commercial sparkling drinks, 3 to 4 liters of gas are needed for every 2 liters of liquid. Therefore, by heating about 16 - 35 grams of sodium bicarbonate, enough gas can be produced. for 2 liters of sparkling drink.
    [0038] According to experiments conducted by the inventor of the present invention, the use of wet powder, suspension or CO2 vehicle solution, such as sodium bicarbonate, can allow the production of similar amounts of CO2 gas, at the same production rate , while heating the solution, suspension or wet powder to a lower temperature, compared to production from dry powder. For example, by heating 25 grams of dry sodium bicarbonate powder to a temperature of 180 SC, 2 liters of CO2 gas will be supplied in approximately 100 - 130 seconds. Using the same amount of sodium bicarbonate in a solution form, the same volume of CO2 gas will be produced, at a similar rate, when heated to a temperature lower than 1802C. It would be appreciated that heating the solution to higher temperatures will provide a higher rate of gas production. However, it should be noted that heating sodium bicarbonate to a temperature above 2002C (degrees Celsius) can cause the sodium bicarbonate particles to be sealed and the C02 can then be trapped within the dust particles. .
    [0039] According to the modalities of the present invention, when using a CO2 vehicle in the state of a solution, a suspension, an emulsion or a wet powder, the solvent used for the solution or the suspension or the fluid used to moisten the powder can be water, edible oil or aromatic oils. Alternatively or in addition, the fluid used as a solvent or to moisten the powder can be a flavored fluid.
    [0040] Reference is now made to Figure 1, which is a schematic illustration of the carbonation system 10, according to the modalities of the present invention. The system 10 can comprise the CO2 production unit 20, which is connected via the gas conduit 23 and through the gas drain plug 24 to the gas drain port 23A. The gas production unit 20 may comprise a base gas production element 20B, a gas production cap element 20A, a thermal power supply unit 20C and a pressure relief valve 20D. The base element 20B and the cover element 20A are designed to form a pressure-tight chamber 21 having two outlets. The first outlet is the connection for gas line 23. This outlet is used to supply pressurized CO2 when system 10 is in use for carbonation. A second outlet is possible via the safety valve 20D, when the pressure inside the chamber 21 is higher than a predefined value. The gas conduit 23 may have, near its distal end, the gas drain plug 24, which can be adapted to be tightly and firmly attached to a container, such as the liquid container 100, and the port of gas flow 23A adapted to be submerged in the liquid container 100, in order to supply CO2 to it. Chamber 21 is designed to accommodate a certain amount of CO2 vehicle material, for example, in the form of a tablet (or capsule), such as tablet 15. When chamber 21 contains CO2 vehicle material, such as bicarbonate sodium, and is sealed tightly, the vehicle material can be heated by the thermal energy supply unit 20C, when energized by electrical energy. When the temperature of the vehicle material 15 reaches the decomposition values, the thermal energy supply unit 20C can be released and, when its pressure rises sufficiently (higher than the normal pressure in the conduit 23 and the container 100 ), the CO2 begins to flow into the container 100 and carbonation of the liquid in the container 100 begins. The production and supply rates of CO2 can be controlled, for example, by controlling the decomposition temperature.
    [0041] Reference is made to Figure 2, which is a schematic illustration of system 200 for supplying pressurized gas for the production of sparkling drinks, according to the modalities of the present invention. In accordance with embodiments of the present invention, the system 200 may include the high pressure chamber 204 comprising the chamber cover element 02A and the chamber base element 02B. The pressure chamber 204 is connectable to the container (or bottle) of liquid 201 through the pressure-sealed bottle feeding pipe 202. The pipe 202 can connect to the chamber 024 at one end and to the bottle 201 through the outlet of 202B tubing at the other end. Pipe outlet 202B can be inserted into bottle 1, and bottle cap 202A can be mounted over pipe 202 to enable sealing of the connection from pipe 202 to bottle 201. The CO2 vehicle material unit 205 can be placed in the chamber 024 before its cap element 02A and its base element 204B are closed stably with each other. System 200 may also include heating device 207 to heat pressure chamber 210 and its vehicle material unit 205 contained therein. When the pressure chamber 204 is closed and heated, the CO2 vehicle material unit 25 inside the pressure chamber 204 will be heated, and the CO2 gas will be released into the pressure chamber 204. The released gas can flow from the pressure chamber 024 to the bottle 021 through the pipe 022, the bottle cap 02A and the pipe outlet 202B. When in operation, system 200 may be under pressure of 20 - 150 psi, or higher. Therefore, the bottle cap 2 02A and the pipe outlet 202B, forming the connection of the system 200 to the bottle 201, must maintain the pressure levels of the system 200 and be sealed to the pressure at those pressure levels, and so must the chamber pressure 02 04, bottle 021 and piping 202.
    [0042] As is well known in the art, the boiling point of a substance is the temperature, at which the vapor pressure of the liquid equals the surrounding pressure of the liquid, and the liquid changes to the vapor phase. Therefore, the increase in pressure surrounding the liquid will result in an increase in temperature, at which the fluid reaches the boiling point. In other words, a liquid at high surrounding pressure has a higher boiling point than when that liquid is at atmospheric pressure.
    [0043] According to some embodiments of the present invention, the CO2 vehicle material can be placed inside the C02 205 vehicle material unit, inside the pressure chamber 024, and can be moistened before heating . When the CO2 vehicle material is heated in a wet form, the fluid serves as a thermal conductor as long as the fluid that moistens the CO2 vehicle material remains in a liquid state. Once the pressure chamber 024 is pressure-sealed, heating the CO2 vehicle material in the pressure chamber 024 raises the pressure in the chamber 204, and therefore raises the temperature, at which the fluid in the chamber 204 evaporates. Therefore, the fluid preserves its thermal conduction characteristics at higher temperatures than under atmospheric pressure and, therefore, remains effective as a thermal conductor during the process of heating the C02 vehicle material to temperatures of more than 100 ° C.
    [0044] According to some embodiments of the present invention, heating device 207 can be an induction heating device. According to other embodiments, heating device 207 can be a microwave heater.
    [0045] System 200 may include a temperature regulator 206, which may include a temperature sensor, for measuring the temperature inside chamber 204 and providing feedback to heating device 207, in order to regulate the temperature for be, for example, between 150 to 400 degrees Celsius. It would be appreciated that, when the CO2 vehicle material, in unit 205, is in a wet form, lower temperatures may be required. In addition, as noted above, when the vehicle material is sodium bicarbonate, heating to a temperature of more than 200 degrees Celsius will not be beneficial.
    [0046] The CO2 vehicle material unit 205 can be supplied in any suitable form, such as powder (whether dry or wet), tablet, capsule, etc. The CO2 vehicle material unit 205 may be mixed or otherwise supplied with various other flavoring materials, which can be released as gas and which mix with the drink. For example, a tablet can include a layer of sodium bicarbonate and a plurality of layers of additives.
    [0047] Reference is now made to Figure 3, which is a schematic illustration of the system 300 for supplying gas for the production of sparkling drinks, according to the modalities of the present invention. The system 300 can be very similar to the system 200 of Figure 2, however, it can additionally comprise a blower 303 to cool the gas flowing in the pipeline 32 0, which can be, for example, in a spiral shape, to allow the more efficient cooling of the gas produced.
    [0048] Reference is now made to Figure 4, which is a schematic illustration of the 400 system for supplying gas for the production of sparkling drinks, according to the modalities of the present invention. The system 400 can comprise the CO2 production unit 20, which is connected, via the gas conduit 23 and through the gas drain plug 24, to the gas drain port 23A. The gas production unit 20 may comprise a base gas production element 20B, a gas production cap element 20A, a thermal power supply unit 20C and a pressure relief valve 20D. The base element 20B and the cover element 20A are designed to form a pressure-tight chamber 21 having two outlets. The first outlet is the connection to the gas line 23. This outlet is used to supply pressurized C02 when the 400 system is in use for carbonation. A second outlet is made possible via the safety valve 20D, when the pressure inside the chamber 21 is higher than a predefined value. The gas conduit 23 may have, near its distal end, a gas drain plug 24, which can be adapted to be tightly attached to a container, such as a liquid container 100, and a gas drain port. gas 23A adapted to be submerged in the liquid in the container 100, in order to supply CO2 to it. The chamber 21 can be designed and can function similarly to the chamber 21 described with respect to Figure 1.
    [0049] According to an embodiment of the present invention, the gas production unit 20 may additionally have an inlet (not shown) for introducing fluid from a source (such as liquid container 100), external to the unit of gas production 20, for the pressure-tight chamber 21, to moisten a CO2 vehicle material placed inside the chamber 21, in solid or dry powder form. It would be appreciated by those skilled in the art that the inlet to chamber 21 may additionally comprise a one-way valve (not shown), to prevent the gas produced in the chamber 21 from escaping through the one-way valve.
    [0050] According to some modalities, the fluid introduced in chamber 21 can be water. According to other embodiments, the fluid introduced into chamber 21 can be water with additives, such as flavor and / or color additives. In still further embodiments of the present invention, the fluid introduced into chamber 21 can be edible oil and / or aromatic oil. According to other embodiments, the fluid can be an oil and water emulsion, such as aromatic oil. It would be appreciated that other fluids can be used.
    [0051] The system 400 may additionally comprise circulation medium 40, such as a pump, which is adapted to pump liquid from the container 100, via the conduit 40A, the distal end of which is adapted to be submerged in the liquid in the container 100, and to return that liquid, via conduit 40B, to container 100. According to one embodiment, conduits 40A and 40B may pass via drain plug 24, however, other embodiments may be used. According to another modality or additional modality, conduits 40A and 40B can pass through a heat exchanger (not shown), to cool the fluid in the conduits 40A and 40B to a desired temperature. The end of the conduit 40B, which it is distal from the circulation means 40, it can be at a distance from the plug 24, which will ensure that it will remain out of the liquid in the container 100, when the container 100 is substantially upright. The liquid that is returned via the conduit 40B can be atomized in the void space of the container 100, for example, by forming the distal end of the conduit 40B, to supply liquid in the form of a spray. The circulation caused by the operation of the circulation medium 40 can improve (i.e., consume the amount of CO2 gas dissolved in the container) and accelerate the dissolution of CO2 in the liquid. The inventor of the invention described in this application found that, when the system 400 is at equilibrium pressure with the pressure inside the container 100, after a certain amount of gas has dissolved, the activation of the circulation medium 40, so that the carbonated liquid is pumped from the container 100 and atomized back into its empty space, it will intensify the rate of dissolution of the gas in the liquid, so that the pressure inside the container 100 drops, due to the additional gas that is dissolved and therefore the pressure produced by the CO2 production unit 20 is now higher than that inside the container 100, and therefore an additional amount of gas is supplied to the container 100. Therefore, the Circulation 40 can be activated, continuously or periodically, during gas production by the gas production unit 20, to enable the dissolution of greater quantities of gas in the liquid. An acidity indicator, which was placed in container 100, indicated a repetitive increase in the acidity of the liquid in container 100, as activation of the circulation medium continued, which indicates that the amount of CO2 gas in container 100 increased with the activation of the medium 40. It would be appreciated that any other system and method known in the art for dissolving CO2 gas in the liquid in the container 100 can be used.
    [0052] Reference is now made to Figure 5, which is a schematic illustration of the system 500 for supplying gas for the production of sparkling drinks, according to the modalities of the present invention. The chamber 20, the conduit 23, the plug 24 and the gas outlet port 23A are constructed and can function in a very similar way in their respective elements in the mode of Figure 1. The system 500 can additionally comprise the pressure control unit 30, comprising pressure transmitter / manometer reading 30A, pressure control unit 30B and heat control line 30C. The pressure of the produced gas can be measured in the gas line 23 or similar place. The gas pressure indication can be provided by the 3 0B pressure control unit. The pressure control unit can act as a simple ON / OFF unit, which can turn off the 20C thermal power supply unit, when the measured gas pressure exceeds a first pre-defined value and restore heating when that pressure drops below a second preset pressure value. In other embodiments, the control unit 30B can perform more complicated control functions, such as a combination of proportional, derivative and integral (PID) of the difference between the measured pressure and a reference value. Other control functions can also be used, to achieve a faster response, a more accurate resulting pressure and the like. It will be apparent to a person skilled in the art that the amount of heat transferred to the active material, such as tablet 15, in Figures 1, 4 and 5, or tablet 2 05, in Figures 2 and 3, has an effect on the total amount and rate of release of gas produced, so that when the amount of heat delivered causes tablet 15 or tablet 2 05 to reach a temperature that is higher than the decomposition temperature, the gas will begin to release and a higher temperature than that will increase the release rate.
    [0053] Heat can be transferred to tablets, according to the modalities of the present invention, in one or more of a list of various heating methods. Reference is now made to Figures 6A and 6B, which are cross-sectional side views of two different forms of gas production units 620 and 630, respectively, made through the middle of the gas production units, and Figures 6C , 6D and 6E, 6F, which are optional top views thereof, according to two embodiments of the present invention. The gas production units 620 and 630 are designed to transfer heat to the respective tablets 650 and 652, in a heat conduction mechanism. Heat is produced in the 620C, 630C thermal power supply unit, which can be formed as heat generators (for example, one or more electric heating elements) and is fed to the 650,652 tablets via the 620B heating chamber base unit, 630B. In order to enable high heat conduction capacity, the size of the surface area that interfaces with the 650, 652 tablets, the internal bottom face of the 520B, 630B base unit is made with heat fins that project from from the bottom towards the inside of the chamber 62 0, 630, respectively. These protrusions form heat fins 622,632, respectively, which, in the views perpendicular to the view plane of Figures 6A, 6B, may have the shape as depicted in Figures 6C / 6D or Figures 6E / 6F, respectively, in which the fins that are project are described by the thick black lines. Tablets 650, 652, will then be formed, respectively, with recesses to loosely fit their respective fins 622, 632. Further improvement in heat transfer can be achieved by using CO2 vehicle material in a wet form, such as sodium bicarbonate solution or moistened powder. As detailed above with reference to Figure 4, according to some modalities, the CO2 vehicle material in tablets 650, 652 can be in a dry form and can be moistened before heating by a fluid introduced in the 620 gas production units and 630, via a fluid inlet (not shown).
    [0054] Heat can be introduced, according to the modalities of the present invention, inside the tablet in the gas production unit, using an induction heating mechanism. Reference is now made to Figure 7, which is a cross-sectional view of the gas production unit 720 made through the middle of the gas production unit, according to the modalities of the present invention. In this embodiment, the thermal energy supply unit 720C, of the gas generation unit 72 0, is formed as an electromagnetic AC generator by induction, as known in the art for induction heating. Tablet 750 includes, spread substantially uniformly inside, iron or ferrous alloy chips. According to some modalities, these chips can be made of another material having high magnetic permeability. When the 720C thermal power supply unit is energized, electromagnetic energy causes the iron / ferrous chips to heat up inside the 750 tablet, which in turn heats the active material in the tablet. In experiments carried out by the inventor of the present invention, it was observed that the power supplied to the 720C thermal power supply unit was equal to the power supplied to the heater operating by the heat conduction mechanism, even though the heating of the tablet, having the same amount of sodium bicarbonate, resulted in heating to the same temperature within the time interval, which was shorter, compared to the heat conduction mechanism, and the amount of CO2 gas produced was greater than compared to the gas produced using the heat conduction mechanism.
    [0055] Tablets made for use with induction heating may comprise a certain amount of ferrous chips calculated to provide sufficient heating within the defined period of time. According to another embodiment, the heat generating material can be carbon chips. The size, spherical density and level of dispersion unit of the chips in the tablet can be selected to achieve the required level of heating and the time required for that heating. According to some embodiments, tablets for the production of CO2 gas may additionally comprise flavor additives, aroma additives, color additives and the like.
    [0056] In experiments carried out by the inventor of the present invention, he found that when heating the tablet using the induction mechanism, the rate of decomposition of the tablet and the rate of gas production can be maintained as in heating by conduction, with lower temperatures in the heating chamber.
    [0057] The heating chamber units 720A and 720B can be made of non-ferrous metals, which will minimize their heating when the electromagnetic energy is activated.
    [0058] Reference is now made to Figures 8A and 8B, which are illustrations of flowcharts of methods for supplying gas, such as CO2, for the production of, for example, sparkling drinks, according to the modalities of the present invention. . In block 810, a system is provided including a pressure chamber and a pressure-sealed bottle feeding pipe, connectable to a bottle. In block 820, the bottle is filled with liquid and is attached to the system in a pressure-sealed manner. In block 830, a CO2 vehicle, such as sodium bicarbonate or another substance that includes carbon dioxide, is placed in the pressure chamber. In block 840, the pressure chamber is pressure sealed and, in block 850, the pressure chamber is heated. As can be seen in block 845, in Figure 8B, according to some embodiments of the present invention, after the pressure chamber is sealed to pressure, fluid can be introduced into the pressure chamber from an external fluid source, such as like from the bottle. The fluid introduced into the chamber can moisten the CO2 vehicle in the pressure chamber and can serve as a thermal conductor. In block 8 60, the CO2 gas, which is released from the vehicle (which is placed in the pressure chamber) flows through the pipe to the bottle. Optionally, circulation medium can be activated to pump liquid from the container and atomize it back into the empty space in the container. The gas is then dissolved in the liquid found in the bottle, in block 870, to create the sparkling drink.
    [0059] According to some modalities of the method according to the present invention, the introduction of fluid into the pressure chamber may precede the heating of the CO2 vehicle inside the pressure chamber.
    [0060] Although embodiments of the present invention have been described with respect to the preparation of sparkling drinks, embodiments of the present invention are not limited to this application. Carbonated liquids can be produced according to the modalities of the present invention for any other suitable application, in which carbonated liquids are required.
