Description

  The present invention relates to a beverage supply pipe cleaning apparatus that is used by being connected to a beverage supply apparatus in order to automatically clean a beverage supply pipe that supplies a beverage.

  For example, a beverage supply device that sells various syrup beverages installed in restaurants, fast food stores, etc., has a bend stage formed in the lower front part of the main body cabinet, and a refrigerator unit and a cooling water tank are mounted inside the cabinet. In the upper part of the bend stage, multiple beverage dispensing nozzles (nozzles for dispensing beverages prepared by mixing dilution water and carbonated water into syrup) corresponding to each beverage are intensively arranged in parallel. The operation panel arranged on the front of the cabinet is provided with beverage selection buttons corresponding to various syrup beverages.

  In addition, a syrup pipe, a dilution water pipe, and a carbonated water pipe leading to each of the beverage dispensing nozzles described above are provided inside the main body cabinet, where the syrup pipe is connected to a syrup tank containing a concentrated syrup at its starting end. In the middle of the piping, a cooling coil and a syrup solenoid valve immersed in the water of the cooling water tank are connected. Moreover, a water inlet solenoid valve, a water pump, a cooling coil immersed in a cooling water tank, and a dilution water solenoid valve are connected to the dilution water pipe connected to the water supply. Further, the carbonated water pipe has a carbonated water solenoid valve connected to a carbonator immersed in the cooling water of the cooling water tank. A carbonator water supply solenoid valve for supplying water to the carbonator from the dilution water pipe is connected to the downstream side of the water pump. Carbon dioxide gas cylinders are connected to each syrup tank and carbonator. Concentrated syrup is pushed out from each syrup tank to each syrup pipe by the supplied carbon dioxide pressure, and the carbonator supplies water to the pressurized carbon dioxide gas. Carbonated water is prepared and stored, and when each designated solenoid valve is opened, it is pushed out by the carbon dioxide pressure and poured out from the beverage dispensing nozzle.

With the above configuration, when a cup is set on the bend stage and the desired beverage is specified with the beverage selection button, the syrup solenoid valve and the diluting water solenoid valve (carbonated water solenoid valve) of the selected syrup pipe are opened simultaneously, and carbon dioxide gas The concentrated syrup pushed out of the syrup tank under pressure and the diluted water (carbonated water) pumped by the water pump are sent to the beverage dispensing nozzle in a fixed amount, and the syrup and diluted water (carbonated water) are mixed in the nozzle. The beverage prepared in this manner is poured out into a cup (for example, see Patent Document 1).
