The operation of the kitchen garbage disposer configured as described above will be described. The garbage put into the garbage storage container 12 is agitated by the rotary blade 14 and crushed by the rotary blade 14 and the fixed blade 13. The drying container 11 heated by the heater 30 transfers heat to the garbage storage container 12 from all around, and the temperature in the garbage storage container 12 rises to heat the garbage. Steam is generated from the heated garbage and is discharged from the discharge port 20 at the top of the garbage storage container 12.

The discharged water vapor is sucked by suction means including a centrifugal fan 26 and a motor 27, passes through an intake filter 39 and an exhaust hose 21, and is deodorized by a deodorizing device 22, and then discharged to the outside. Therefore, there is no unpleasant smell during drying, and the crushed and dried garbage remains in the garbage storage container 12, but has a reduced bulk and is easily discarded. No dripping or mold formation. Therefore, until the garbage storage container 12 is full, the garbage can be put on the dried garbage and dried. Therefore, compared to garbage, it is possible to convert the garbage into garbage that is easier to handle, reduce in weight and easier to process.

Since the garbage storage container 12 has a mortar shape, the gap between the outer wall of the garbage storage container 12 and the inner wall of the drying container 11 is set so as to gradually become narrower upward. Therefore, the temperature of the bottom of the drying container 11 near the heater 30 becomes high (about 250 ° C.), but the bottom has a large gap between the garbage container 12 and the drying container 11, so that the garbage container 12 The temperature is kept low (about 130 ° C.).
