At this time, when the air in the treatment tank comes into contact with the cooler in the water treatment chamber, the moisture contained therein is condensed, and the air is discharged to the outside of the apparatus as droplets. Most of the air from which water has been removed is reheated by passing through the reheating chamber and returned to the treatment tank through the air return port, and the rest passes through the deodorizing chamber, where it touches the deodorizing catalyst, and the odor molecules are chemically reacted. It is decomposed into another substance and becomes odorless and discharged.
Since the internal pressure of the processing tank is reduced by the amount of the discharged air, fresh air flows in through a gap between the inlet and the processing tank.

By cyclically repeating such a process, the air in the treatment tank is efficiently and continuously removed of water, the discharged air is deodorized, and aerobic fermentation is maintained.

The second feature of the present invention is that the treatment tank is used for multiple purposes to maximize the cost performance and space factor of the apparatus.

A blade is provided, and the stirring blades are attached to the rotating shaft at mutually different angles.

By doing so, when the garbage is fed from the waste feeding hopper, the fermentation bacterium is preliminarily charged in the lower part of the treatment tank, so that the fermentation with the garbage fed with the rotation of the stirring blade is carried out. Mixing with bacteria is performed.
At the same time, air is supplied to the fermenting bacteria by stirring.

The first located just below the waste input hopper
When food waste is thrown into the compartment, the overflow occurs, and the overflowed portion flows into the second compartment through the notch in the upper part of the partition plate, and when the second compartment overflows, the overflowed portion Flows into the third compartment, and the overflowed portion in the third compartment is discharged to the outside of the processing tank. In this way, the processed material is transferred from the upstream side to the downstream side.

Further, the stirring blades in the first section, which is located directly below the waste feeding hopper in the processing tank, are formed in a substantially "U" shape, and a plurality of them are provided at a small interval. The fixed blade extending from the inner wall of the processing tank is provided between these stirring blades, and the fixed blade is a receiving blade extending substantially radially from the vicinity of the rotation axis toward the inner wall of the processing tank,
