However, in the above-mentioned invention, even if the raw material is agitated in the rotary fermentation tank, the hot air passes through the rough part of the raw material and the part with a small raw material layer, Since the air did not flow evenly inside, the average temperature rise was slow and the supply of fresh air was lacking. As a result, fermentation was slow and fuel efficiency was poor. Further, since the gas exhausted from the device is exhausted from the input side, it is exhausted with a considerable odor of the raw material. For this reason, a deodorizing device is required for deodorization, and the device as a whole cannot be made compact. Therefore, in order to solve the above drawbacks, it is necessary to provide a means for the hot air to uniformly flow in the raw material. Further, it is desirable that the gas discharged from the fermenter can be deodorized without a separate device because of the installation space and cost.

[Specific Process Example] Here, a specific process example will be described. The raw material for compost is fed from the hopper 22 to the charging chamber 2
, And enters the rotary drum 1 from the charging chamber. In the rotary drum 1, the rotation of the drum and the feed blade 11
The raw material is agitated and mixed by the product take-out chamber 3
Sent to the side. The fresh hot air sent by the blower fan 21 passes through the raw material and is exhausted from the I-type exhaust pipe 10 through the deodorant 13 in the penetration chamber 4 by the intake action of the exhaust fan 15. While Exhaust gas is exhausted from the entrance 10 ₁ of the type I breather 10 with a considerable odor in the raw material, the deodorized while passing through the deodorizing agent 13 in the through chamber 4, has disappeared almost odor Can be released into the atmosphere. If you want to completely deodorize, you can guide the exhaust gas into the soil and deodorize the soil. In the rotary drum 1, the raw material is rapidly changed uniformly into a favorable environment in which aerobic microorganisms grow. The temperature rises above a certain temperature, fresh air is constantly supplied, and drying and fermentation of the compost raw material are rapidly promoted, and the product is taken out from the outlet 22 of the take-out chamber 3 as a product. A temperature sensor 19 is provided in the take-out chamber 3, and when the temperature exceeds a set temperature, the burner 18 is automatically extinguished, and the damper 16 is narrowed to reduce the exhaust gas amount, so that the air introduction amount is also decreased.
Further, when the temperature becomes lower than the set temperature, the burner 18 is automatically ignited, the damper 16 is expanded, and the amount of exhaust increases, so that the amount of air introduced also increases. This allows the raw material to be fermented under constant conditions. Further, the burner 18 can be appropriately extinguished and ignited.
