Abstract

An on demand carbonation system is shown for carbonating water or a noncarbonated beverage. A flow restrictor (17) meters a predetermined quantity of pressurized carbon dioxide to a T-fitting (23) for combination with a known quantity of the liquid as delivered thereto by a pump (25). The carbon dioxide and liquid flow therefrom through a turbulator (32) for enhancing the absorption of the gas by the liquid. The liquid and gas then flow through a heat exchange cooling coil (38) for further absorption of the gas as the liquid is cooled in the coil. The coil is connected to a dispensing valve (39) for dispensing of a cooled carbonated beverage therefrom.

Description

TITLE: Carbonation System

FIELD OF THE INVENTION:

The present invention relates generally to equipment used to carbonate beverages or plain water, and in particular to such equipment designed to carbonate on a demand basis.

BACKGROUND OF THE INVENTION:

Various carbonation systems exist that purport to provide for a more rapid combination of water and carbon dioxide gas (CO₂) for permitting the production of carbonated water on an as needed basis. Such approaches to carbonation offer the possibility of reducing the size of or eliminating the traditional carbonating tank, and providing a volume of carbonated water that is not limited by the size of the tank nor the systems ability to replenish the supply produced therein. Some on demand systems utilize the strategy of increasing the surface area of contact between the CO₂ and the water. However, many such systems, while effective in large bottling facilities, do not translate well to the far smaller size constraints of fountain beverage dispensing machines. Other carbonating strategies are also known that utilize specialized structural geometry's for combining water and carbon dioxide or microporous materials to enhance the mixing and/or area of contact there between. However, these approaches, while meeting the size constraints of small fountain systems, have not found any real success or acceptance in the marketplace as the level of carbonation provided thereby is generally too low for commercial purposes. Accordingly, it would be desirable to find an on demand carbonating system that meets the size criteria of fountain beverage dispensers and that delivers desired levels of carbonation.

A further problem in the beverage dispense industry concerns carbonated pre-mix beverages. Pre-mix beverage is produced at a bottling facility wherein pre-mix tanks are filled with the finished beverage, in much the same manner as are individual serving sized bottles and cans. The tanks are then transported to the location where needed, often for a temporary facility at an event such as a sporting game or county fair. At the dispense location, the tanks are connected to a pressurized source of carbon dioxide that serves to drive the beverage from the tank, through a cooling device and ultimately into a cup or other receptacle. A main advantage of pre-mix, as opposed to bottles and cans, is that the pre-mix tank is much more efficient in terms of size and ease of handling than would be an equivalent volume of beverage held in a large number of such smaller serving containers. Also, once opened, the contents of a bottle or can must be used at that time, as the carbonation is lost rapidly, and as there would be no practical way of insuring or preserving the sanitary condition thereof. However, pre mix tanks must be fairly robust in that they are required to safely contain the pressure inherent in the beverage itself as well as the dispense pressure. In addition, they must endure the rigors of transport, sterilizing and reuse. Also, they must not affect the quality or flavor of the pre- mix beverage, which beverage can be quite corrosive. As a result of the foregoing, pre- mix tanks are made of stainless steel, which is one of the main factors contributing to the relatively high cost thereof. Accordingly, it would be desirable to have a system for pre- mix dispensing that can utilize a far less expensive container.

An additional problem with current pre-mix systems concerns the further uptake of carbon dioxide into the beverage that can occur during any long periods where the pre- mix tank is connected to the CO₂, such as during periods of low usage. The further uptake happens as the driving pressure is typically specified to be somewhat above the saturation pressure causing further carbonation of the pre-mix in excess of a desired amount. Lowering of ambient and beverage temperatures can also result in further uptake of CO₂ This over carbonating situation results in the undesirable production of excess foam upon dispensing of the beverage. The over carbonating is of course due to the fact that CO₂ is used, as referred to above, for the driving dispensing force. Thus, the pre-mix tank functions in the manner of a carbonator tank wherein the pre-mix absorbs "free" or "excess" CO₂ present therein. Other relatively inert gases, such as nitrogen, could be used for the purpose of driving the beverage, however the bacteriostatic properties afforded by the carbon dioxide gas would then be lost and the nitrogen would undesirably replace some of the carbon dioxide in the beverage. Accordingly, it would also be desirable to have a pre-mix system that is not susceptible to over carbonating of the beverage, but that does not compromise the resistance to biological contamination thereof afforded by carbon dioxide gas.

SUMMARY OF THE INVENTION.

The present invention concerns an improved water carbonation system and an improved system for dispensing pre-mix carbonated beverages. The present invention includes a source of pressurized CO₂ connected to a gas line having a flow restriction means such as a small orifice or needle valve therein, which is in turn fluidly connected to a solenoid valve. The pressurized gas line then extends from the solenoid valve to a T-fitting. A pump is connected to a source of potable water and serves to pump the water along a water line to the T-fitting. A carbonated water line extends from the T-fitting and flows to a turbulating means. The line then extends from the turbulating means to a heat exchange coil of a beverage dispensing machine and ultimately to a dispensing valve.

In operation, the pump is set at a flow rate to deliver a predetermined volume of water to the T-fitting at a predetermined high pressure, well above the saturation pressure of the gas and water at a given temperature. The flow restricting means delivers or meters a predetermined volume or flow rate of carbon dioxide gas to the T-fitting at a predetermined pressure above that of the water. Both flow rates are calculated to combine a known volume of gas with a known volume of water such that when fully combined, i.e. when the CO₂ is fully absorbed in the water, carbonated water of a particular desired carbonation level is produced. The CO₂ and water are initially mixed at the T-fitting and flow therefrom through the turbulator and along the carbonated water line. As the CO₂ and water flow there along, the gas is absorbed into the water and the turbulator serves to enhance that combination. At the beverage dispenser, the mixture of CO₂ and partially carbonated water is cooled, for example, by flowing through the serpentine coils of a cold plate, which cooling and residence flow time through such coils serves to complete the full absorption of the gas in the water.

Once the carbonated water has reached the dispensing valve, all of the gas has been absorbed by the water wherein it is then carbonated to the desired level. As a result thereof, a carbonator tank is not required. The on demand production of carbonated water as provided by the present invention is determined by, the high system pressure of the water as well as the high pressure of the CO₂, the pre-set flow rates, the effectiveness of the turbulating means, the cooling ability of the dispenser with respect to cooling capacity thereof and residence time of the CO, and water as they flow through the cooling coils thereof.

In a second related embodiment of the present invention, all of the components are the same as above described, except that the pump is connected to a bag-in-box container having therein a volume of pre-mix beverage. The pre-mix beverage is specialized in that it has been produced at the bottling facility without carbonation, i.e., flat water and syrup have been combined in the desired ratio. Lacking carbonation, it can be asceptically packaged in a bag-in-box container. Then, by use with the system of the present invention, this specialized pre-mix is carbonated in the manner as described above to any predetermined level of carbonation specified. Thus, the pre-mix beverage is combined only with an amount of CO₂ that will provide for the desired level of carbonation thereof, assuming full absorption thereof. In this manner, an over carbonating situation is eliminated as there is no excess of CO₂ present, as CO₂.is not used to drive the dispensing of the pre-mix and is not otherwise added in an amount that is in excess of the level of carbonation desired. In other words, the CO, is only metered in as beverage is dispensed and for the sole purpose of carbonating to a predetermined level based on an assumption of essentially full absoφtion. This pre-mix system of the present invention therefore allows the use of much less expensive bag-in-box containers to replace the traditional and more costly metal pre-mix tanks. In a further third embodiment, the specialized pre-mix is made on site. The water is pumped from a source thereof , as with the first above described embodiment, however the beverage syrup portion is held in, for example, a bag in box container. A ratio device is used that is fluidly connected to both the water and syrup sources and combines them to form the specialized or uncarbonted pre-mix. This pre-mix then flows to the T-fitting for carbonating as per the first and second above described embodiments. Such ratio devices are well known in the art, and serve to combine two liquids, and can be driven by the pressurized water provided by the pump wherein the water flow drives or pumps the syrup from the source thereof.

A schematic representation of a first embodiment of the beverage dispensing system of the present invention is seen in Fig. 1 and generally referred to by the number 10. System 10 includes a cylinder of pressurized CO₂ 12 having a regulator valve 14 and connected by a pressurized gas line 15 to a check valve 16. A flow restrictor 17 is connected in line 15 and followed by a solenoid valve 20. Various types of flow restrictors are known in the art, such as, cap tubes, flow washers, flow restricting tubes and needle valves. In a preferred embodiment of the present invention, the flow restrictor comprises a flow restricting tube 21, as illustrated in cross-section in Fig. 2. Tube 21 is connected in line 15 and includes two tube attachment ends 21a, a reduced diameter interior portion 21b and a tube abutment disk 21c. As is known in the art, restrictor tubes can be obtained having a wide variety of specific reduced internal diameters. Line 15 then extends from restrictor tube 21 to solenoid 20 which is, in turn, fluidly connected to a first inlet of a T- fitting 23. A fluid line 24 provides for connecting a source of potable water to an inlet of a pump 25 and for fluidly connecting an outlet of pump 25 to a second inlet of T-fitting 23. A check valve 26 is connected in line 24 between the source of potable water and pump 25.

A fluid line 30 extends from an outlet of T-fitting 23 and includes a turbulator portion 32. As seen in Fig. 3, a portion of line 30 includes a turbulating structure 34. A turbulating structure can consist of a wide variety of structures that by their mere presence in a line through which a fluid is flowing, cause the fluid to be mixed or agitated as it flows into and collides with the various surfaces thereof. Turbulator 34 is well known in the art and, as seen by referring to Fig.'s 3-5, comprises a plastic molding that includes a plurality of angularly positioned surfaces 34a and protrusions 34b extending therefrom transverse to the axial extension thereof. These surfaces provide for agitating the water and carbon dioxide as they flow within tube 30 past turbulator 34, i.e., they provide for causing a random turbulent flow as opposed to a more uniform laminar one. Fittings on either end of the turbulation section 32, not shown, or indentations 35 of line 30 at either end of turbulator 34 can serve to retain turbulator 34 in place therein. Those of skill will realize that the turbulator need not be a separate structure from the tube. For example, the tube can include a plurality of surface indentations that intrude into the internal volume thereof thereby causing a desired agitation. Or, various structures, such as rods, can be secured to the tube surface and extend through holes therein into the tube internal flow channel for disrupting the flow therein.

Line 30 extends from turbulating portion 32 to a beverage dispensing machine 36. Line 30 then connects to a cooling heat exchange line 38 of dispenser 36. As is known in the art, line 38 is typically bent in a serpentine fashion and extends through an electrically cooled water bath or through an ice cooled solid metal cold plate. Line 38 is then connected to a beverage dispensing valve 39. Valve 39 is of the solenoid operated post- mix type that is operated by a switch that is generally pushed directly, or contacted by operation of a lever arm 39a. An electrical control mechanism, not shown, provides for turning on pump 25 and opening solenoid 20 upon activation of the switch of valve 39.

Operation of valve 39 to dispense a beverage causes the simultaneous opening of solenoid 20 and operating of pump 25. Restriction tube 21 permits a known quantity of CO₂ to flow there past to fitting 23 as a function of a predetermined pressure, as set by regulator 14. Likewise, water is pumped at a predetermined flow rate to fitting 23 and initially combined with the CO₂ therein. This mixture then flows along line 30 to turbulating structure 34. The surfaces 34a and 34b thereof serve to mix the flow of carbonated water and free gas to enhance further combination thereof. This absorption also occurs as the mixture flows through the carbonated water line 38 of dispenser 36 wherein cooling thereof takes place. As is known, lower temperatures enhance the ability of water to absorb CO₂. After traveling the length of coil 38 and suitably cooling the water, all of the remainder of the metered gas is absorbed therein as it reaches valve 39. The flow rates of the water and gas are calculated so that a known volume of water is combined with a known volume of gas whereby a desired level of carbonation is reached once all the gas is absorbed. Those of skill will understand that a separate syrup line, not shown, is connected to each post-mix valve 39. Thus, when valve 39 is operated, fully carbonated water is mixed with syrup in the proper ratio to produce a desired beverage.

Dashed lines 46 and 47 indicate where lines 24 and 15, respectively, could be extended so that pressurized tank 12, regulator 14, check valve 16, pump 25 and check valve 26 could be placed at a location remote from dispenser 36 and its associated restrictor 17, solenoid 20, T-fitting 23 and turbulator 32.

A modification of post-mix dispensing embodiment 10 is seen by referring to Fig. 6 and is generally designated by the numeral 40. 11 is well understood that post-mix dispensers typically have more than the one valve 39 shown in dispenser system 10 of Fig. 1. Post mix embodiment 40 includes a dispenser 41 having plurality of valves 39. A manifold 42 provides for connection of the valves 39 to cooling coils 38. In the present invention, it is important that the flow rates of the water and gas be kept constant so that the proper amounts thereof are mixed together. That is also true for post-mix with respect to insuring that the correct ratio between the syrup and water is maintained. Hence, systems are well known to prevent the operation of two or more valves at the same time as the attendant pressure drop can affect the quality of the beverage and slow its dispensing to an unacceptable rate. Embodiment 40 provides for the simultaneous dispensing from any two valves 39 by providing for two gas delivery restrictor circuits having two restrictors 17 and 17a, and two solenoids 20 and 20a connected to CO₂ source 12 by a T-fitting 18. A pump 43 is also required that provides for a constant flow rate and pressure down stream thereof and where pump 43 is connected to both restrictor circuits by two additional T-fittings 23. An example of a pump 43 is the "Pentaflex" model made by the Flojet Corporation of Irvine, California. Two turbulator structures 32 and 32a are, in turn, individually fluidly connected to one of the restrictor circuits. A normally closed solenoid valve 21 regulates flow to turbulator 32a, and the flows leaving each turbulator structure 32 and 32a are connected to their respective coils 38 and 38a. In operation, it can be appreciated that dispenser system 40 provides for the operation of one valve 39 or two valves 39 simultaneously. A control mechanism, not shown, prevents three or more valves 39 from being operated simultaneously. When any two valves 39 are operated at the same time, the second solenoid 20a is also operated so that twice the amount of CO₂ is available for carbonating. Pump 43 senses the added demand and operates to deliver twice the volume of water while maintaining the predetermined pressure. Solenoid valve 21 is operated with solenoid valve 20a so as to direct half the doubled water flow to turbulator 32a. Turbulator structures 32 and 32a are then both available to turbulate this increased flow. Thus, manifold 42 receives twice the flow rate of carbonated water in order to satisfy the carbonated water requirements of the two valves being operated at the same time.

A third embodiment of the present invention is seen in Fig. 7, and generally referred to by the numeral 50, wherein like components are numbered the same as with the previous embodiment. As seen therein, line 24 is connected to a bag-in-box supply 52 of pre-mix beverage instead of a supply of potable water. A bag-in-box system, as is known, includes a rigid outer box 54, made typically of cardboard, and an internal liquid retaining flexible plastic bag 56. Bag 56 is aseptically filled at a bottling facility with pre-mix wherein a syrup and highly filtered water are combined in the proper ratio. However, unlike current pre-mix which comprises a fully finished carbonated drink, the present inventions contemplates the use of a specialized pre-mix. This specialized pre-mix would be the same as the current variety in all aspects, except that it would not be carbonated.

A pre-mix valve 58 is secured to a pre-mix dispenser 59, wherein valve 58 is fully manually operated by movement of a lever arm 60 thereof. A different means for signaling pump 25 and valve 20 to operate is required than with a post-mix valve 39. Lever arm 60 thereof can be used to operate a switch 62 that provides such a signal. Alternately, a pressure sensing switch 64 can be located in line 30 whereby a sensed reduction in pressure therein below a predetermined level causes pump 25 to operate and valve 20 to open when valve 58 is opened, and where pump 25 is turned off and valve 20 closed when a predetermined high pressure is sensed after the closing of valve 58.

In operation, the bag-in-box 52 is connected to line 24 wherein the contents thereof flows therefrom by the operation of pump 25 when valve 58 is opened. Valve 20 is simultaneously opened and the specialized pre-mix is then carbonated to the desired level in the same manner as described above for the potable water. As is known in the art, the ability of the bag thereof to collapse permits pumping out of its contents without the need to vent to atmosphere. Thus, the potential to contaminate such contents is thereby greatly reduced. In this system, dispenser 59 will often be of the ice cooled variety having a cold plate wherein line 38 will extend in a serpentine fashion there through. In a pre-mix application, those of skill will appreciate that there exists a single and separate line 38 and pump 25 for each pre-mix valve 58 of dispenser 59 as well as a separate restrictor means 17, valve 20 and turbulator structure 32. It can be appreciated that pre-mix system 50 eliminates the need for multiple expensive metal pre-mix tanks for each flavor. And eliminates the possibility of over carbonating, as only the needed amount of CO₂ is combined with the uncarbonated pre-mix wherein no excess of carbon dioxide is used to drive the beverage. The second embodiment can also have various components at a remote location from dispenser 59 as indicated by dashed lines 46 and 47.

A fourth embodiment is seen in Fig. 8 and generally designated by the numeral 70. With system 70 the specialized pre-mix is made on site rather than at a bottling plant. In this system, a beverage syrup is retained in a container, such as, a bag in box container 72. Potable water is then pumped from a source thereof along a line 74 by pump 25 to a first inlet 76a of a ratio device 76. The syrup is delivered along a line 78 to a second inlet 76b of the ratio device 76. Device 76 then combines the water and syrup in a desired ratio, typically five parts water to one part syrup and dispenses that uncarbonated pre-mix from an outlet 76c thereof. Ratio devices are well known in the art and serve to combine two liquids in such predetermined ratios wherein one of the fluids is provided thereto at a pressure. The pressurized or driving fluid serves to operate ratio device to pump the non pressurized fluid, the syrup in the present example. Thus, device 76 pumps the syrup from container 72 and combines it with the water at the desired ratio. Examples of such ratio devices specifically designed to ratio syrup and water are seen in US patents RE35780 and 5,476,193, incorporated herein by reference thereto. Other examples of ratio devices are seen in US patent No's 5,454,071 and 4,684,332. The uncarbonated pre- mix is then pumped from the ratio device 76 to the T-fitting 23 and subsequently carbonated in the same manner as described above relative to the previous embodiments. In embodiment 70 ratio valve 76 could be positioned at a remote location along with the other components as described above and as indicated by dashed lines 46 and 47.

The systems of the present invention could be used to carbonate a wide variety of beverages in addition to soft drinks and carbonated water, such as, juice drinks and beer. With respect to beer, it is understood by those of skill that many beers are processed in ways that can essentially temporarily remove the carbonation initially present therein as a result of the fermentation process. CO₂ is, of course, then added back in after completing the various processes involved in making the finished product, such as, filtering and pasteurizing. Thus, in a manner similar to the uncarbonated pre-mix, systems 50 and 70 could be utilized to add the carbonation to uncarbonated otherwise fully processed beer that is retained in aseptically filled bag in box containers. A major advantage would be that the uncarbonated beer would not have to be refrigerated prior to or even during use. Also, inexpensive bag in box containers could be used in place of the heavier and more expensive metal or wood barrels, thus reducing the costs of transportation and eliminating the need for cleaning.

In a preferred embodiment of systems 10, 50 and 70, the restriction tube 21 has an internal restricted diameter of .016 inch and pump 25 is set to provide a flow rate of the water or uncarbonated pre-mix of 2 ounces per second at nominally 100 pounds per square inch (psi). Tube 21 is supplied with a CO, at a pressure of 130 psi creating a flow of gas of .3 cubic feet per minute. This volume of specialized pre-mix or water, and gas, when fully combined, results in the desired carbonation level of 3.7 volumes of gas. Line 30 has a diameter of approximately .25 inch and turbulator 34 fits therein and is approximately 8 inches long. Line 38 has an inside diameter of nominally .25 inch and extends approximately 40 feet through a cold plate or water bath being constantly maintained at approximately 32-34 degrees Fahrenheit. It was found that these particular embodiments permitted a continuous draw of 2 ounces per second having 3.7 volumes of carbonation and a temperature in the desired range of between 34 to 40 degrees Fahrenheit.

These systems achieve essentially 100% absorption of the CO₂ metered into the liquid carried in line 30, and therefore the amount of gas calculated to be metered into the fluid is equal to the amount of gas retained by the fluid at the desired carbonation level. It can be understood that an important factor in the full absorption of the CO, is the over pressure thereof with respect to the water. The water or pre-mix pressure is set at a level well above the saturation pressure thereof for most encountered ambient temperatures of the water or pre-mix. The CO, must be set at a higher pressure still to be driven into the water. This pressure regime of the system serves to essentially take the temperature of the incoming water or pre-mix out of the carbonation equation in that, even at relatively high ambient water temperatures, e.g. 70 degrees Fahrenheit, the gas will be readily absorbed into the water, i.e. the applicable saturation pressure is well exceeded. The turbulating of the gas and liquid followed by the cooling thereof as it flows through the cooling coil 38 then serves to further exceed the applicable saturation pressure parameters so as to complete and insure the complete gas/liquid combination. Moreover, it can be appreciated that the high pressures, turbulating and cooling combine to insure that this absorption of gas occurs relatively rapidly so that a true on demand system is provided. Since only the precise amount of gas needed to carbonate to a desired carbonation level, assuming total absorption thereof, is metered into the water or specialized pre-mix, there is no excess amount of gas to result in over carbonation or foaming.

Those of skill will readily realize that various modifications can be made in tube lengths and restriction diameters, pressures, flow rates and so forth to achieve different desired levels of carbonation. It was found that if the pressure of the CO₂ was sufficiently high and that the length of coil 38 was sufficient to cool an otherwise fully carbonated drink in a traditional application, assuming that the beverage is maintained at the desired temperature range of 34-40 degrees Fahrenheit, at a particular constant flow rate, then there would be adequate time to permit the full absorption of all the CO₂ as metered therein. The turbulation means is not absolutely required, but can provide for a more practical system in terms of pressures required and length of cooling coil.

Those of skill will understand that the completeness of carbonation in a post-mix situation is not as critical as that for pre-mix. As long as the water is adequately carbonated, a post-mix valve has the ability to release some excess gas at the nozzle without the excess causing foaming of the dispensed beverage. In a pre-mix application, nonabsorbed gas can more readily result in foaming of the dispensed drink due to the nature of the valve structure, and that the carbonation is breaking out of or agitating the beverage as opposed to escaping primarily from the less viscous water.
