Since the water extracted by the action of the dewatering rotary 33 or the dewatering piston 35 gives off an odor, fresh water is emitted from the washing shower 36 to wash the inside of the dewatering case 32. The waste water after cleaning is discharged from the drain pipe 37. Further, the raw garbage after the compression dehydration process is discharged from the discharge port 38.

C. Heating Type FIG. 4 is a side sectional view showing a configuration example of a heating type garbage processing machine. In the garbage disposal shown in FIG. 4, the garbage put in the processing container 41 is stirred by the stirring blade 43 driven by the motor 42. Further, the air heated by the heater 44 is blown onto the garbage by the blower fan 45 to heat and evaporate the water contained in the garbage.
The water vapor thus generated from the garbage moves through the gap between the processing container 41 and the heat insulating container 46 and contacts the inner surface of the dehydration tank 47. The dehydration tank 47 is the processing container 4 to be heated.
1 is shielded by a heat insulating container 46,
It is cooled by the cooling fan 48. For this reason, the water vapor that has touched the inner surface of the dehydration tank condenses, and water droplets flow to the bottom. These water drops pass through the drain pipe 49 and drain container 50.
Stored in. Further, the odor emitted by the waste water stored in the drain container 50 passes through the exhaust pipe 51, the odor is weakened by the catalyst deodorizing section 52, and is discharged from the exhaust duct 53 to the outside of the garbage disposal. In the garbage disposal shown in FIG. 4, dry solid matter or dry powdered waste remains in the processing container 41 after the treatment is completed.

D. Electronic incineration type FIG. 5 is a side sectional view showing a configuration example of an electronic incineration type garbage disposal. In the garbage processing machine shown in FIG. 5, the garbage thrown into the primary combustion chamber 51 is first irradiated with the microwave oscillated by the magnetron 52 to heat and carbonize the garbage. Further, the carbonized garbage is heated in the secondary combustion chamber 53 by the heating heater 54 and then ignited and incinerated by the ignition heater 55. Smoke generated during the burning of garbage is removed from the exhaust top portion 57 after passing through the catalyst 56, soot is removed.
