PROBLEM TO BE SOLVED: To achieve an effective deodorization by sucking the exhaust gas from a fermentation tank for fermenting and decomposing the garbage by using an exhaust fan. SOLUTION: In this device, an introducing pipe 64 for leading exhaust gas to a deodorizing device 62 is provided with an openable and closable exhaust port 64b, the upper part of the exhaust port is covered with a pivotally supported openable and closable cover 78, and the exhaust gas volume of an exhaust means for sucking the exhaust gas is made adjustable corresponding to the intermittent driving of an agitating click shaft. Then the exhaust gas volume is reduced on agitation, and the exhaust gas volume is increased on agitation stoppage, and when the exhaust gas volume is increased, the cover of the exhaust port can be opened by wind pressure thereof. |
