The beverage storage tank 200 is connected to the cooler 300 and the second transfer line 250. In the beverage storage tank 200, the gas injected from the gas storage tank 100 through the first transfer line 150 is contained in the beverage and the beverage is transferred to the second transfer line 250 by the pressure of the gas. It is transferred to the cooler 300 through. The second transfer line 250 preferably has an even cross-sectional area of the inner flow path.

The cooler 300 is connected to the beverage supply unit 400 and the third transfer line 350. The third transfer line 350 is preferably formed evenly in the cross-sectional area of the inner passage. The cooler 300 serves to cool the beverage rapidly by cooling the beverage transferred from the beverage storage tank 200 through the second transfer line 250.

In the beverage supply unit 400, the beverage cooled by the cooler 300 is discharged to the outside via the third transfer line 350. That is, the beverage rapidly cooled in the cooler 300 is discharged to the outside through the beverage supply unit 400 is injected into the container. More specifically, an opening through which the beverage is injected is formed at the bottom of the container, and the container is mounted on the beverage supply unit 400 so that the opening and the nozzle (not shown) of the beverage supply unit 400 are connected to each other. Injecting the beverage into the container. In this regard, reference to the prior art is omitted. The beverage supply unit 400 is provided with an operation unit 410.

This is because excessively injected, the volume of the beverage that is transferred to the cooler 300 and cooled increases, so that the flow rate excessively rises above the reference value. Therefore, the increase in the flow rate of the beverage above the predetermined reference value in the third transfer line 350 having the same cross-sectional area means that the flow rate of the beverage in the third transfer line 350 is abnormally increased. do.

For example, as shown in FIG. 2, if the discharge capacity B per unit time displayed on the display unit 411 is 6 cc per 0.1 second, and the coefficient C for the discharge capacity per unit time is 1.3, the reference value is 7.8 cc per 0.1 second (6 cc). The discharge capacity of * 1.3) is expressed in units of ml / sec, and 78 ml / sec is the reference value. Accordingly, the solenoid valve 520 is kept open when the flow rate detected by the flow meter 510 is less than the reference value of 78 ml / sec, and the flow rate detected by the flow meter 510 is 78 ml / If the sec or more is closed by the control unit 530 prevents the beverage to be transferred to the beverage supply unit 400 is discharged to the outside of the beverage supply unit 400 is excessively generated foam of the beverage injected into the container in all directions It will be able to prevent splashing and splashing. In addition, when the solenoid valve 520 is closed and the beverage is not discharged through the beverage supply unit 400, the user easily recognizes that the beverage stored in the beverage storage tank 200 is exhausted and the beverage storage tank 200. Can be replaced.

The operation of closing the solenoid valve 520 by the controller 530 when the flow rate is greater than or equal to the predetermined reference value may be turned ON / OFF through the operation unit 410. That is, when the operation is ON in the use item (A), the solenoid valve 520 is closed by the controller 530 when the flow rate is equal to or greater than the preset reference value, and the operation is performed in the use item (A). If the flow rate is OFF, the solenoid valve 520, which is above or below the predetermined reference value, remains open.
