Next, the operation of the organic waste fermentation apparatus configured as described above will be explained.

First, conditioning materials (wood chips, sawdust, rice grains, etc.) are used to adjust the moisture content of organic waste such as livestock manure.
The mixed material (hereinafter referred to as raw material) is supplied to the circulation conveyor 16 by a separate raw material supply conveyor (not shown) that is attached and engaged with the circulation conveyor 16.

The supplied raw material is transferred to the traveling conveyor 7 via the inclined conveyor 17 and the supply conveyor 18.
In this case, the left end 7a of the traveling conveyor 7 is moved to the upper left side of the processing chamber 1a in advance, as shown in FIG.

The raw materials are fed into the processing chamber 1a from the traveling conveyor 7 via the feeding conveyor 8 in an average manner in the width direction. In this case, by moving the traveling conveyor 7 little by little to the right, the raw materials are evenly fed into the processing chamber 1a in the longitudinal direction.

The raw material charged in the processing chamber 1a is stored for 4 to 10 days, and during this time the auger 3 is occasionally driven to cut the raw material, and at the same time, the auger 3 is ventilated through a pipe 3a from an external blower installed at the lower center. conduct. This air permeates into the raw materials and rises as the primary fermentation process takes place.

When the primary fermentation process is completed, the screw conveyor 9 at the bottom of the processing chamber 1a is driven to move the screw conveyor 9 sequentially from the left end to the right, and the raw material is transferred to the take-out conveyor 14.
Since the inner wall of the processing warehouse 1 is sloped, the raw material moves smoothly downward and is quickly carried out.

The primary fermented raw material taken out to the take-out conveyor 14 is transferred to the inclined conveyor 17 via the circulation conveyor 16, and then transferred to the supply conveyor 1 in the same manner as above.
