Each beverage break sensor 24a-24d detects the beverage break of each container AD by detecting the amount of foam contained in the sparkling beverage flowing through each beverage supply pipe 21a-21d, and electrically controls the detection signal. Output to the circuit 30. Each of the electromagnetic valves 25a to 25d is electrically controlled to be opened and closed by the electric control circuit 30, and each container A to D is connected to the dispenser via the manifold 22 in the open state, and each container in the closed state. Close containers A-D. In addition, as this electromagnetic valve 25a-25d, in order to reduce the unevenness | corrugation in a drink circuit, it is made to employ | adopt a ball valve.
[0010]
The manifold 22 is also provided with a defoaming beverage outlet 22f, and the defoaming beverage outlet 22f is connected to the drainage port 13 provided on the side wall of the housing 10 via the drainage pipe 26. A beverage sensor 27 and an electromagnetic valve 28 are interposed in the drain pipe 26. The beverage sensor 27 detects the presence or absence of a sparkling beverage in the drain pipe 26 by detecting conductivity. The electromagnetic valve 28 is electrically opened and closed by an electric control circuit 30, and in the open state, the beverage supply pipes 21a to 21d are connected to the drain port 13 via the manifold 22 and drained in the closed state. The mouth 13 is closed.
[0011]
Next, operation of the sparkling beverage supply container switching device configured as described above will be described. In using this apparatus, first, each of the beverage inlets 11a to 11d is connected to each of the containers A to D, and the beverage outlet 12 is connected to the beverage inlet of the dispenser. The carbon dioxide gas is supplied to the container A to D, and the sparkling beverage in each container A to D is pumped to the device, and then the beverage circuit of the device is filled with the sparkling beverage. In this case, the electric control circuit 30 first opens the electromagnetic valves 25 a and 28 to flow the sparkling beverage from the container A to the drain port 13, thereby discharging the air in the beverage circuit from the container A to the drain port 13 to the drain port. It discharges from 13 and is filled with a sparkling beverage in the same circuit. When the beverage sensor 27 detects the completion of the filling, the electromagnetic valve 28 is closed, then the electromagnetic valve 25a is closed, and then the electromagnetic valves 25b and 28 are opened, and the container B to the drain port 13 are opened in the same manner as above.
