PURPOSE:To provide a supplying apparatus for gaseous CO2 which can be handled safely even in the average family by combining a fermentig vessel in which yeast is allowed to act on saccharide with a gaseous CO2 cleaning vessel, a path provided with a filter layer for airtightly connecting both the vessels, and a gas exhaust and supply port provided with a ckeck valve for exhausting gaseous CO2 from the cleaning vessel. CONSTITUTION:A fermenting liq. 2 for gaseous CO2 consisting of org. matter as a nitrogen source, and aqueous soln. of essential inorg. salt or the like as a culture soln., yeast, and starting material for fermentation based on saccharide such as sugar or glucose is poured in a fermenting vessel 1 from the charge inlet 3. The saccharide is decomposed into gaseous CO2, alcohol, etc. After removing water droplets, the generated gaseous CO2 is passed through a filter layer 4 to remove yeast, and it enters a cleaning vessel 5. While the gaseous CO2 passes through a gas cleaning agent 6 such as activated carbon, alcohol and the odor of yeast are removed, and the cleaned gaseous CO2 is supplied to an apparatus using gaseous CO2 from a gas exhaust and supply port 8 having a built-in valve 9 preventing reflux by a pressure difference. |
