Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a carbonated beverage dispensing device, and more particularly to a carbonated beverage dispensing device capable of supplying a highly carbonated beverage and a low carbonated beverage from separate beverage supply valves.

As shown in FIG. 1, this type of carbonated beverage supply device is equipped with, for example, three beverage supply valves 2a, 2b, and 2c on the front surface of a main body 1, and each of these beverage supply valves has different types and carbonic acid concentrations. We are now able to supply carbonated drinks. Beverage supply valve 2a,
2b and 2c are normally used to allow the beverage to flow out from the outlet nozzle 4 when the valve lever 3 is pushed rearward.

Conventionally, carbonated drinks with a low carbonation concentration have been produced by first mixing highly carbonated water and diluted water on the supply side of the beverage supply valve to create low carbonated water, and then adding this and the syrup stock solution by opening the beverage supply valve. By outlet nozzle 4
It is made by mixing parts. However, since the passage after passing through the valve body of the beverage supply valve is extremely short, there is a drawback that the two liquids cannot be mixed sufficiently.

Therefore, an object of the present invention is to provide a carbonated beverage dispensing device that can properly mix and supply syrup stock solution and carbonated water even in the case of carbonated beverages, especially beverages with low carbon dioxide concentration.

The invention is based on diluting the syrup concentrate with dilution water before entering the beverage supply valve, and mixing this with highly concentrated carbonated water after the valve is opened. According to this, the concentrated syrup stock solution is diluted with water in a relatively long path and then mixed with carbonated water, making it possible to supply a properly mixed low carbonated drink. become.

Hereinafter, an explanation will be given using FIG. 2 showing an example.

In FIG. 2, three beverage supply valves 2a, 2
b, 2c are syrup supply pipes 5a, 5b, 5, respectively.
c to the syrup cylinders 6a, 6b, and 6c. Two of these syrup cylinders 6a and 6b store concentrated syrup stock solution for highly carbonated beverages, and the remaining one 6
C stores concentrated syrup stock solution for low carbonated beverages. Syrup cylinder 6a, 6
The syrup stock solutions b and 6c are supplied to the syrup supply pipes 5a, 5b, 5c by the carbon dioxide gas pressure in the carbon dioxide cylinder 7.
The water is pumped through the liquid to the beverage supply valves 2a, 2b, 2c. This pumping amount is determined by the syrup flow rate adjustment valves 8a and 8.
b and 8c can be adjusted separately.

Furthermore, all the beverage supply valves 2a, 2b, 2c are connected to the common carbonated water production apparatus 1 via a carbonated water supply pipe 9 that is different from the syrup supply pipes 5a, 5b, 5c.
1 is connected. The carbonated water production device 11 is connected to a carbon dioxide cylinder 7 via a carbon dioxide gas supply pipe 12 and to a water supply tank 14 via a pressurized water supply pipe 13 . The pressurized water supply pipe 13 is provided with a pressurizing pump 15 and a solenoid valve 16. In this way, the carbonated water manufacturing device 11 supplies water from the water tank 14 to the carbonated water manufacturing device 11 by opening the solenoid valve 16 and driving the pressurizing pump 15.
It is possible to produce carbonated water mixed with carbon dioxide gas from the carbon dioxide cylinder 7. Note that the water level in the water supply tank 14 is controlled to be approximately constant by opening and closing a solenoid valve 17.

Further, the portion of the pressurized water supply pipe 13 between the pressure pump 15 and the electromagnetic valve 16 and the syrup supply pipe 5c for the syrup stock solution for low carbonated beverages are connected to each other by the dilution water collection pipe 18. There is. In this way, only the syrup supply pipe 5c for the syrup stock solution for low carbonated beverages is connected to the water supply tank 1.
4 is supplied as dilution water, thereby making it possible to dilute the syrup stock solution before it reaches the beverage supply valve 2c. At this time, the mixing ratio of carbon dioxide gas, water, and syrup stock greatly affects the taste.
It is necessary to adjust as appropriate using the syrup flow rate adjustment valve 8c, the carbonated water flow rate adjustment valve 19, etc.

Furthermore, if the dilution water sent by the pressure pump 15 is injected into the pot 21 through the outlet nozzle 4 while remaining at a high pressure, the flow rate of the dilution syrup is high, resulting in increased generation of bubbles, which is undesirable. Therefore, it is desirable to insert a resistance pipe 22 into the dilution water sampling pipe 18 to lower the outflow pressure. By appropriately selecting the diameter and length of this resistance tube 22, the flow rate can also be selected. Note that the same effect can be obtained by using a pressure reducing valve instead of the resistance pipe 22.

Further, in order to prevent dilution water from flowing into the syrup cylinder 6c when the pressure pump 15 is activated, a check valve 23 is provided in the syrup supply pipe 5c. On the other hand, in order to prevent syrup from flowing into the dilution water sampling pipe 18 when the pressurizing pump 15 is stopped, a check valve 2 is also installed in the dilution water sampling pipe 18.
is provided.

In such a carbonated beverage supply device, when the valve lever 3 of the beverage supply valve 2c is pushed backward, a switch installed at the top of the valve is activated to turn on the pressure pump 1.
5 is driven, the solenoid valve 16 is closed, and dilution water is sent into the syrup supply pipe 5c, so that the syrup stock solution is diluted before reaching the beverage supply valve 2c. Therefore, this diluted syrup and highly concentrated carbonated water are then supplied to the beverage supply valve 2c.
By mixing at the outlet nozzle 4, it is possible to supply a properly mixed low carbonated beverage. It goes without saying that when the valve levers 3 of the other beverage supply valves 2a, 2b are pressed, a highly carbonated beverage is supplied.

In addition, although the case where the number of beverage supply valves is three was explained above, it goes without saying that other numbers may be used.
