PURPOSE:To efficiently produce desired low concn. carbonated water by stably supplying CO2 gas to raw water. CONSTITUTION:Water supply piping 11 to which raw water is supplied, the gas piping 12 connected to the water supply piping 11 so that raw water meets carbon dioxide and receiving the supply of carbon dioxide, and a gas storage part 9 provided to the gas piping 12, fine pipe part 6 and check valve 7 are provided. The CO. gas stored in the gas storage part 9 is pressurized in the fine pipe part 6 to open the check valve 7 to easily obtain desired low concn. carbonated water. Apparatus constitution is simple and compact. Low concn. carbonated water can be continuously obtained. |
