In the present embodiment, the pressure of the carbon dioxide gas 7 is reduced to 0.7 MPa, and the pressure is desirably 0.75 MPa or less at the maximum. By making such a pressure, the pressure of water supplied from a water supply line 5 described later can be reduced to 0.95 MPa or less in the present embodiment, and production of carbonated water not subject to the application of the high-pressure gas safety method. While being able to be set as the apparatus 1, the apparatus can be reduced in size.

The carbon dioxide supply line 3 constantly supplies carbon dioxide 7 to the mixing tank 9.
As shown in FIG. 3, the water supply line 5 includes a water supply source 4 using tap water, a water treatment filter 20 connected to the water supply source 4, and a downstream of the water treatment filter 20. A water supply valve 21 provided in the water supply valve 21, a water supply pump 22 provided downstream of the water supply valve 21, and a check valve 23 provided between the water supply pump 22 and the mixing tank 9.

  This water supply line 5 is connected to the upper part of the mixing tank 9 in this embodiment, and when water 6 is supplied to the mixing tank 9, the water 6 naturally falls into the mixing tank 9 as it is. However, when the water 6 is supplied from the water supply line 5 to the mixing tank 9 by providing an injection nozzle at the end of the water supply line 5, it may be supplied by spraying.

  In the present embodiment, the water supply pump 22 pumps tap water 6 supplied at 0.3 MPa from the water pipe 4, which is the water supply source 4, at 0.95 MPa, and the pressure on the secondary side of the water supply pump 22. Is preferably adjusted so that the pressure inside the mixing tank 9 is a pressure value (less than 1 MPa) at which the high-pressure gas safety method is not applied and is about 0.2 MPa higher than the pressure of the carbon dioxide gas 7. .

  A water supply valve 21 provided in the water supply line 5 is connected to an upper level sensor 24 provided in the mixing tank 9 via a control unit 25, and a water surface ( The controller 25 is controlled to open and close so that the liquid level is located.

  In the present embodiment, the mixing tank 9 is a cylindrical tank having a diameter of 100 mm and a height of 300 mm, and the water supply line 5 and the other end portion 10b of the circulation line are connected to the upper surface of the mixing tank 9 from the upper part thereof. A carbon dioxide gas supply line 3 is connected to the side surface. In this embodiment, the carbon dioxide supply line 3 is connected to a position 75 mm from the upper surface.

  The upper surface of the mixing tank 9 communicates with the inside of the mixing tank 9, and when the pressure in the mixing tank 9 becomes high, a relief valve 26 that automatically discharges the carbon dioxide 7 to the atmosphere, and carbon dioxide A blow valve 27 for manually discharging 7 to the atmosphere is provided.

Further, since the sprayed carbonated water 8 adheres to the inner wall surface of the mixing tank 9 and flows downward, the contact time between the carbonated water 8 and the carbon dioxide gas 7 can be greatly increased. By such an action, even if low pressure carbon dioxide gas 7 and water 6 which is not extremely low temperature (about 1 ° C.), for example, water 6 having a temperature of about 1 ° C. to 10 ° C., preferably about 1 ° C. to 5 ° C. are used, The concentration of carbonated water 8 can be obtained.

Chiller water such as beer server is used. Thus, even when a fluid having a temperature of about the temperature of chiller water of a beer server is used, the carbonated water 8 can be circulated through the circulation line 10 to obtain a highly concentrated carbonated water 8. By using such a cooling means 11, the apparatus 1 for producing carbonated water of the present invention can be further downsized.

  By the way, in this embodiment, although the plate-type heat exchanger is used as the cooling means 11, other well-known cooling means (heat exchanger etc.) can be used.

  Examples of the beverage 15 supplied from the beverage supply line 18 include a soft drink stock solution (syrup), alcohol such as shochu, whiskey, fruit liquor, spirits, brandy, and sake.

  Further, as shown in FIG. 6, the carbonated water production method 32 of the present invention includes a carbon dioxide supply step 33 for constantly supplying carbon dioxide 7 to the mixing tank 9, and water for supplying water 6 to the mixing tank 9. The supply process 34 and the liquid (carbonated water 8) in the mixing tank 9 are circulated either continuously or intermittently in this embodiment, preferably continuously, and the carbon dioxide gas is dissolved in water at a high concentration to increase the concentration. A carbon dioxide gas dissolving step 35 for producing carbonated water having a concentration and a carbonated water supply step 36 for supplying carbonated water 8 produced in the mixing tank 9 are constituted.

The timing is determined.

As described above, the carbon dioxide gas dissolving step 35 is a step of manufacturing the high-concentration carbonated water 8 by constantly circulating the carbonated water 8 in the mixing tank 9 to the circulation line 10 in the present embodiment.
The carbonated water 8 produced in this way is supplied to the outside from the supply nozzle 14 through the carbonated water supply line 13 in the carbonated water supply process 36.

  In addition, it is good also as the method 37 which dissolves carbon dioxide gas with high concentration in water, without performing the carbonated water supply process 36.
