The detection means (not shown) detects the closing, and the control circuit energizes the electric motor 22, and the agitator 34 rotates to mix the carrier and the garbage. Garbage is decomposed into carbon dioxide and water by microorganisms cultured on a carrier and composted.

By driving the fan 18, the air in the treatment tank 1 circulates through the circulation path, vaporizes the water generated by the decomposition of the garbage, and maintains the water content of the carrier within the optimum range for activating microorganisms and the like. At the same time, it supplies oxygen necessary for activation of microorganisms. A part of the air circulating in the processing tank 1 is discharged to the exhaust pipe 13
It is prevented that the air in the processing tank 1 is exhausted to the outside of the main body case through the exhaust passage 14 and the exhaust port 15 from the rear part of the tank and the moisture removal efficiency in the processing tank 1 is improved. , To improve the efficiency of garbage disposal by activating microorganisms.

As the air in the processing tank 1 is exhausted to the outside, the outside air is sucked into the main body case from the intake port formed in the lower case 4, and the processing tank is sucked from the suction port formed in the upper surface of the processing tank 1. It is inhaled into 1. The air sucked into the main body case is heated by the planar heater 2 mounted on the outer surface of the processing tank 1 and is mixed with the air circulating in the processing tank 1. It does not significantly lower the temperature and does not adversely affect the garbage disposal efficiency. Furthermore, since the planar heaters 2 are attached substantially symmetrically on both sides of the opening 4 of the processing tank 1, the inside of the processing tank 1 can be uniformly and entirely heated. Can be used for garbage processing.

Next, the replacement work of the carrier will be described. When the shutter 41 is pulled forward and the opening 3 at the bottom of the processing tank 1 is opened, the carrier drops from the opening 3 into the container 44 and is stored.

When the container 44 is full, the shutter 41 is attached and the opening 3 is closed.

At the time of throwing in the garbage, there is a risk of accidentally throwing in unprocessable substances such as beer lids, and those requiring time to process beef or pork bones, etc. Is gradually moved to the bottom of the processing tank 1 by the rotation of the agitator 34. Since the edge of the opening 3 at the bottom of the processing tank 1 is extended downward, a space is formed between the rotation trajectory of the stirring blade 37 and the periphery of the opening 3, and the hardly decomposable foreign matter is stored in this space.

Since the hardly decomposable foreign matter is first discharged from the opening 3 when the shutter 41 is opened, almost no foreign matter is mixed in the carrier discharged thereafter, and it can be used as it is as compost. it can.
