Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to an apparatus and method for dispensing post-mixed cold beverages using compressed gas as the pneumatic force for a dispenser.

A generally accepted procedure and construction for dispensing a subsequent blended beverage utilizes a stainless steel syrup tank.

The tank is filled with Drink F1 at a bottling or distribution center, pressurized, and then transported to the site of use. The tank is always pressurized and is connected to a carbon dioxide bottle during dispensing to maintain pressure. To be economically viable, the tank volume must be about 5 gallons or the cost per unit volume becomes very high. However, this 5 gallon tank is extremely heavy, limiting its use to commercial distribution channels such as restaurants and bars. Operating continuously pressurized tanks requires an educated and understanding user who can connect and disconnect pressurized tanks without leakage. After use, pressurized tanks must be returned for cleaning and refilling before being transferred to the next location, and therefore two-way transportation over a given path is commercially necessary. The pressurized tank is a household drinking R1 dispenser,
Not suitable for household distribution channels or for use by unskilled personnel.

Another way to use pressurized tanks is as a package called a box-in-a-bag (BIB). A BIB consists of a plastic bag inside a cardboard box. The bag is not pressurized and the drinker is pulled out of the bag by a suction pump, which may be electrically or gas powered6.
BIB has been successful only with non-alcoholic beverage syrups. There were a number of problems including pump failure, leakage, pump burnout, seal failure and other causes. B.I.
B has been very successful for wine applications that do not require the use of a pump.

2-5 to make BIB an economically viable package
It had a volume of gallons. Small volume packages, such as retail containers, are typically not lightweight and effective. B.I.
Fluid communication to B is cumbersome and leaks are very frequent. Attempts have been made to devise a compressed gas powered drink dispenser that does not require electricity to power the drink pump.

Although technically successful, these examples are extremely complex, failure-prone, and expensive.

Although these devices were embodied in relatively expensive vending machines, they were not successful on the market. Vending machines are very difficult to clean, store, sanitize, and repair. Prior art devices also failed to combine a beverage pump and tank into a simple, leak-proof package.

5+ does not have any holes so there is no possibility of leakage. The pump 16 is attached to the bottom 6 of the tank 15 by means of a retainer 63, which is an inwardly directed recess that holds the pump 16 in the bottom 62 of the tank 15.
2. Syrup pump 16 is in fluid communication with the interior of tank 15 at its inlet, and fill check valve 57 is in fluid communication with the interior of tank 15 .
5 is automatically checked to prevent the syrup from flowing into the pump 16, and the syrup is automatically closed to prevent the syrup from flowing back from the pump 16 to the tank 15. The drink r1 outlet 56 is connected to the minute-'5 conduit 50, and this minute! The j-conduit has a normally closed check valve and a half-open release device 51 that easily connects and disconnects from the release device 52. The bag 59 divides the inside of the pump 16 into a pressure chamber 84 and a thrust chamber 85. The propulsion port hole 58 extends into the propulsion chamber 85 and the disengagement device 4

The ribbon 16 can be taken in and out of the tank 15 manually.

When the apparatus 10 of the invention is operated to carry out the method of the invention, compressed gas bottles 13 containing carbon dioxide are introduced into the cooling chamber 12 and connected to the supply conduit 18 . gas bottle 1
3 is a preset pressure regulator 17 that cannot be changed by unauthorized persons.
, the gas connector 20 fits into the outlet of the regulator 17, so that there is no need to set pressure in the device 10 and the regulator 17 cooperates with the gas bottle 13 to supply gas and the regulator 17 The person filling the gas bottle 13 inspects it. Regulator 17 maintains a predetermined preset pressure of 25 PSIG. When so connected, the dispensing valve 19, water tank 14, etc. are all supplied with gas pressure. The water supply conduit 23 is connected and opened to maintain the compressed gas headspace 31 above the water level and fill the aquarium 14 with water to a predetermined level. Water is sprayed into the aquarium 14 for carbonization, and a native porosity (not shown) allows carbon dioxide gas to flow down to the bottom of the aquarium 14 if the device 10 is conditioning a carbonated beverage. do. Each syrup tank 15 is filled 23- with beverage syrup. Examples of beverage syrups, sometimes referred to as condensates, are song juice, punch, tea, plain wine, cold coffee, and dairy drinks. Examples of syrups for carbonated beverages are cola, lemon-lime, orange, energy drinks, etc. If an alcoholic beverage is to be served, the alcoholic beverage can be placed in the tank 15. During initial filling of each tank 15, a holder 63 holds the air-filled pump 16 against the bottom 21 of the tank 15 to prevent the pump 16 from floating to the top of the tank 15 and turning upside down. pump 1
6 is filled with gas, the actuator 66 is pushed down and the valve element 48 is pushed in. When compressed gas is supplied to the pump 16, the bag 19 is expanded and air is expelled from the pressure chamber 84. By releasing the actuator 66, the valve element 48 returns to its normal position and the thrust chamber 85 of the pump is vented back to the atmosphere, causing the bag 59 to deflate as the beverage flows into the pumping chamber 84 due to the loss of the uncompressible tank 15. A second such priming actuator typically purges air from the dispensing conduit 50 to fill the device 10 with beverage. Similarly, pump 16 and dispensing conduit 50 are all primed. When freezing begins, the water tank 14 is provided with reference to the refrigeration cooling by downward drafts on three sides, in particular the left, rear and right sides, and the more or less important syrup tank 15 is provided with what remains. Device 1
When chilled overnight, both the water and syrup are cooled to the same humidity, just above the freezing temperature of, for example, 35°C (1°C). After filling and cooling, the adjustable flow controller 54 is manually set to provide the correct ratio of syrup flow and water flow so that the device 10 is ready to dispense the type of beverage to be mixed later. The water tank 14 and each tank 15 each hold at least one day's supply of cold water and syrup.

When dispensing a dose of syrup, the selected actuator 6
Press down on 6. Actuator 66 pushes valve element 48 down. The depressed valve element is the dispensing valve inlet 35
．． 36 in fluid communication with outlets 37, 38 thereby connecting the gas source 13 to the respective pump 16 and servo 42 for the selected beverage.

Servo 42 opens water valve 29 and water flows back out of nozzle 30 under gas pressure maintained in headspace 31 . When valve element 48 is in the dispensing position, gas source 13 is still in fluid communication with water tank 14 via actuated dispensing valve 19. At the same time, as soon as the same gas pressure is applied to pump 16, syrup begins to be discharged from nozzle 30. 1
Once the dose has been dispensed, the actuator or 15 button 66 is released and the spring-loaded valve element 48 returns to its normal position, cutting off fluid communication between the inlet 35.36 and outlet 37.38 and the source of compressed gas. The servo 42 and each pump 16
The outlet ports 37, 38 are connected to the vent hole 41, and the pump 16 and the valve 42 are communicated with the atmosphere.

The propellant gas used by the pump 16 and servo 42 is ~
It is immediately released into the atmosphere inside the cooling chamber 12. The same predetermined head pressure in the servo 42 drops quickly due to the small volume, and when replenishing the pumping chamber 84 with syrup it takes only a few seconds to empty the thrusting chamber. The syrup in pump 16 is always kept at least as cold as the syrup in tank 15, so that the water and syrup are separated at approximately the same temperature and pressure. The flow of syrup and water is through nozzle 3.
0 and decarbonized with compressed air or carbonized with carbon dioxide to form a cold mixed beverage. Transfer of the syrup from tank 15 to pump 16 takes place entirely within tank 15 and there is no possibility of leakage or contamination.

In the illustrated device, there are four actuators 66 and four dispensing valves 19, but only three syrup tanks 15 and three pumps 16. The fourth actuator 66 and dispensing valve 19 are for carbonated water, cold water, etc.

One of the outlets 37 of the dispensing valve 19 is connected to a servo 42 and the other outlet 38 is plugged. The fourth actuator 66, dispensing valve 19, is advantageously selected for tasteless carbonated cold water.

The tank 15 and pump 16 are removed from the device 10 by disconnecting the hook 40.51 to change the flavor or to clean or sanitize the tank and pump. A normally closed check valve 52 prevents seepage from the nozzle 30. Tanks 15 and pumps 16 drain completely automatically from the fill opening and dispensing conduits 27-50 when they are inverted. A holding body 63 holds the pump 16 when the tank is turned upside down. Pump 16 is not easily removed from tank 15 and all tank 15 and pump 16 can be cleaned in a washing machine.

The advantages of the apparatus 10 and method of the present invention are many.

One notable feature is that the device 10 is noiseless. no cooling fan, no mechanical push button or latch, no release of compressed gas from dispensing valve 19, servo 42 and aquarium relief valve 32 and regulator 17;
The operating noise of the propulsion and supply conduits and pump 16 is constant. ] Except for the pressure 74, the device 10 is silent.

The dispensing valve 19 and servo 42 discharge the propellant gas into the cooling chamber and reduce the possibility of frost buildup on the evaporator 15 since the used propellant gas is dry and releases moisture-laden air. . The device 10 dispenses multi-flavored beverages without the use of electrical or complex components. Air and liquid connections are reduced to a minimum so that there is no leakage if these connections are damaged. The device 10 is a multi-flavor dispenser that does not use electrical or mechanical switches, 28 actuators and mechanisms, and does not use multi-stage water valves and conduits. The ratio of syrup to water can be easily adjusted and very precisely replicated since the syrup and water are at the same temperature and pressure. syrup tank 15
The pump 16 and the pump 16 are not normally pressurized, and only the pump is intermittently pressurized. The water used in most cases is cooled first. Tank 15 and pump 16 are easy to clean and flavor changes are easy. Since the syrup does not come into contact with metal and is made of metal, the taste will not deteriorate. The quality of the beverage dispensed by the device 10 is so excellent that the beverage is comparable to the quality of the beverage dispensed from glass bottles. Most importantly, the device 10 is so simple that it can be used for domestic purposes. The device is hygienic, simple, very reliable, does not leak, is easily cleaned, does not explode, and can be inspected and repaired if it does not work as intended.

Those skilled in the art will recognize that other advantages may be seen and realized, and that various minor modifications may be made, and it is to be understood that such modifications are within the scope of the present invention.
