On the other hand, the water vapor containing the uncondensed odorous component is introduced from the exhaust pipe 42 to the deodorizing device 44, where the odorous component is purified and discharged to the outside. The dried food waste remains in the food waste storage container 31, but the volume is reduced, and since the water activity is reduced due to drying, the food waste may be put into the food waste storage container 31 as it is, and may be putrefaction. No mold will be generated. Therefore, until the garbage storage container 31 is full, the garbage can be put on the dried garbage one by one and dried. Then, the dried food waste remaining in the food waste storage container 31 and the condensed water accumulated in the condensed water container 43 are periodically collected and discarded.

Since these drying processes are always performed in the state where fresh air is inhaled, the dry waste is not over-burnt and is finished in a state containing aerobic bacteria. . Further, since the air hole 50 has a small diameter, the amount of leakage is small, the drying processing time is not affected, and the odor leakage is small. The lid 45 is provided with a suction port 51 and a communication port 53 so that the air passage created by the blower fan 49 also passes through the lid 45. Therefore, the odor leaking from the air hole 50 is drawn by the blower fan 49 and discharged from the deodorizing device 44. It is mixed with odorless air, diffused and discharged from the exhaust port 54. Therefore, the odor during use is not a concern.
