Abstract

PURPOSE:To absorb and dissolve gaseous CO2 sufficiently in a liquid mixture by connecting a feeding pipe of gaseous CO2 and a feeding pipe of the liquid mixture to a producing tank separately. CONSTITUTION:A liquid mixture is fed to a producing tank 18, and the pressure of gaseous CO2 passing through a CO2 feeding pipe 2 is set to a specified value by a reducing valve 3. Then, cooling operation of the producing tank 18 is performed using a cooling device. At the same time when the liquid mixture in the producing tank 18 begins to get cold, the gaseous CO2 becomes more easily absorbable in the liquid mixture. Therefore, the pressure of gaseous CO2 decreases below the specified value. When the pressure decreases to a certain degree, the liquid mixture is saturated with CO2. In this state, the pressure of gaseous CO2 supplied to the producing tank 18 is held at a specified value, and carbonated beverage in the producing tank 18 is discharged through a discharging cock 19.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a carbonated beverage production apparatus for producing a carbonated beverage by mixing a liquid mixture containing water and carbon dioxide gas and cooling the mixture.

In conventional carbonated beverage production apparatuses, carbonated beverages are produced by separately providing a mixing tank for mixing a liquid mixture and carbon dioxide gas and a cooling tank for cooling the mixed beverage. In such conventional methods, if the temperature of the liquid mixture supplied to the mixing tank changes, the carbon dioxide content in the carbonated beverage changes.

Moreover, since the mixed liquid is generally not at a low temperature, a carbonated beverage with sufficient carbon dioxide content cannot be produced unless the pressure of carbon dioxide gas is increased.

The object of the present invention is to eliminate the need for a mixing tank as described above;
To provide a small and lightweight carbonated beverage manufacturing device that can sufficiently absorb and dissolve carbon dioxide gas into a liquid mixture even if the pressure of carbon dioxide gas is set to a low level, and that can easily vary the carbon dioxide content in the carbonated beverage. It is to be.

Next, a preferred embodiment of the carbonated beverage manufacturing apparatus of the present invention will be described in detail with reference to the drawings.

The carbon dioxide gas cylinder 1 pressurizes a storage tank t storing weakly carbonated water via a pressurizing pipe 6, and also pressurizes a stock solution tank Z storing a stock solution via a pipe 1. Furthermore, carbon dioxide gas is supplied to a production tank/g for producing carbonated beverages via a carbon dioxide gas supply pipe, and the production tank is pressurized with this gas. The flow rates of the weakly carbonated water in the storage tank S pressurized by carbon dioxide gas and the stock solution in the stock solution tank 7 are adjusted by the flow rate regulators // and 9 provided in the supply pipes 16 and /3, respectively, and are checked. Mixed in mixer, 2o via valves /, 2 and 10. The mixed liquid in the mixer O is sent to the production tank via the supply pipe. The supply pipe/7 is equipped with a solenoid valve/3 for determining the supply amount of the mixed liquid passing through this pipe.
is provided. The carbon dioxide gas supply pipe is provided with a pressure reducing valve 3, a check valve for preventing backflow of beverage from the production tank 7g, and a three-way valve 3 for degassing. The pressure reducing valve J determines the pressure of the carbon dioxide gas sent to the production tank 7g and determines the carbon dioxide content in the carbonated beverage in the production tank lt. By setting the pressure of the carbon dioxide gas sent to the production tank/g to a low level and restricting the amount of gas supplied through the carbon dioxide gas supply pipe with a throttle valve (not shown), the production tank/gas pouring cock/ Various problems when dispensing a carbonated beverage through the tap 9 can be improved (for example, the problem that carbon dioxide gas instead of the beverage passes through the beverage and blows out from the pouring tap) can be improved.

A cooling device connected to the production tank supplies the mixed liquid to the production tank/g, sets the pressure of the carbon dioxide gas passing through the carbon dioxide gas supply pipe to a predetermined value using the pressure reducing valve 3, and performs a cooling operation of the production tank/g. (not shown). Generally, the amount of carbon dioxide gas absorbed and dissolved in a solvent is determined by the pressure of carbon dioxide gas in the solvent and the temperature of the solvent, and is particularly highly dependent on the temperature of the solvent. That is, when the temperature of the mixed liquid in the production tank/S decreases, carbon dioxide gas becomes easier to dissolve in the mixed liquid. Therefore, as soon as the mixed liquid in the production tank it begins to cool down, carbon dioxide gas becomes easily absorbed by the mixed liquid, and as a result, the pressure of carbon dioxide in the production tank lt drops from the predetermined value, and when it drops to a certain level, the pressure in the mixed liquid It becomes saturated with carbon dioxide gas. In this state, the pressure of carbon dioxide gas supplied to the production tank is maintained at a predetermined value. If cooling operation continues further, 1g of production tank
The mixed liquid in the tank begins to freeze and the carbon dioxide pressure in the tank gradually rises, whereby the supply of carbon dioxide to the production tank/g is stopped by the three-way valve S.

In this way, the production tank l, which is a mixed liquid containing carbon dioxide gas,
The carbonated beverage in S is dispensed via a dispensing cock.

The gas pressure in the production tank when dispensing the carbonated beverage is higher than the initial predetermined carbon dioxide gas pressure, and decreases as the carbonated beverage is dispensed. Then, when the gas pressure in the production tank IT falls below the initial predetermined pressure, carbon dioxide gas is again supplied to the tank by the three-way valve 5.

As described above, according to the carbonated beverage production apparatus of the present invention, the mixed liquid supply pipe and the carbon dioxide gas supply pipe are separately connected to the carbonated beverage production tank connected to the cooling device, so that the gas inside the production tank is Carbon dioxide gas is automatically supplied via the carbon dioxide gas supply pipe depending on the pressure state, and mixed with the mixed liquid at a low temperature to be dissolved. Therefore, more carbon dioxide gas can be dissolved in the mixed liquid, and the pressure of carbon dioxide gas supplied to the production tank can be set lower. Additionally, since the conventional mixing tank is not required, the device becomes smaller and lighter. In addition, conventionally, no device has been disclosed that focuses on the pouring characteristics such as the pouring speed of beverages, but if this device is further provided with a pressure reducing valve in the carbon dioxide gas supply pipe, the pressure of the carbon dioxide gas supplied to the production tank can be reduced. It is possible to easily change the carbon dioxide content in carbonated beverages by adjusting the gas pressure, and by setting the gas pressure to a low level, the speed of pouring out the beverage can be lowered. By squeezing, various problems during pouring can be improved.
