However, the conventional fermentation treatment apparatus described above has the following problems. (A) Until the fermentation progresses to some extent in the treatment tank and the odorous components are decomposed, an unpleasant odor is generated from the object to be treated such as sludge and animal droppings. . Further, once the odor has leaked from the processing tank to the outside, there is no way to treat it, and this is the biggest factor that deteriorates the working environment. (B) When treating sludge or animal dung with a high water content, fermentation does not proceed even if the treatment tank is kept at an appropriate temperature and stirred.
It takes too long for the amount of water to be fermented efficiently. Therefore, rapid processing cannot be performed, and sufficient processing capacity cannot be obtained.

[Function] An object to be treated, such as sludge or animal droppings, is introduced into a treatment tank of a fermentation treatment apparatus through an inlet, and an appropriate amount of high-temperature aerobic fermentation bacteria (for example, trade name: Bio Colony, Bio Heat: Bio Special Co., Ltd.) is added. Mix and stir with stirrer. The heat-resistant temperature of these high-temperature aerobic fermenters is about 120 ° C. The odor in the processing tank is transferred to the combustion chamber by the atmosphere transfer device together with the atmosphere. Odor components in the atmosphere are burned in a combustion chamber, and the generated combustion gas is discharged to the outside, for example, from an exhaust chimney while heating the treatment tank through a combustion gas ventilation passage.

The object to be treated in the treatment tank is heated to evaporate moisture, sent to a combustion chamber together with the atmosphere, passed through a combustion gas ventilation passage, and discharged to the outside, for example, from an exhaust chimney. The combustion in the combustion chamber is stopped when the water content of the material to be treated reaches a suitable ratio for fermentation. As the fermentation of the processing object proceeds in the processing tank, the atmosphere transfer device is operated as necessary or intermittently, and the outside air is introduced into the processing tank. The fermentation product in the treatment tank is heated by combustion in the combustion chamber, adjusted to a water content suitable as a product such as fertilizer, and taken out from the outlet of the treatment tank.

(Operation) The operation of this embodiment will be described with reference to FIGS. (1) An object to be treated such as sludge or animal dung is introduced into the treatment tank 1 of the fermentation treatment apparatus K from the introduction port 13, and an appropriate amount of high-temperature aerobic fermentation bacteria is mixed and stirred by the stirring device 2. This stirring is performed by rotating the rotation axis of the motor M in the forward and reverse directions to reciprocate the object to be processed in the processing layer 1. (2) The odor in the processing tank A is transferred to the combustion chamber 4 by the atmosphere transfer device 3 together with the atmosphere. During operation of the atmosphere transfer device 3, the inside of the processing tank 1 has a negative pressure, so that the internal odor hardly leaks to the outside.

(3) The odor component in the atmosphere is burned in the combustion chamber 4 and almost completely burns by coming into contact with the high temperature portion while passing through the ventilation hole 43 of the honeycomb tube 42.
It is deodorized. Further, the combustion gas generated in the combustion chamber 4 passes through the combustion gas ventilation path 5 and is discharged from the exhaust chimney 6 to the outside while heating the processing tank 1. (4) The object to be treated in the treatment tank 1 is usually heated to about 100 ° C. to evaporate the moisture, sent to the combustion chamber 4 together with the atmosphere, passed through the combustion gas ventilation path 5, and discharged from the exhaust chimney 6 to the outside. You. In addition, since the high temperature type aerobic fermentation bacterium does not die at 100 ° C., there is no influence on the subsequent fermentation action. Then, when the water content of the material to be treated reaches a ratio suitable for fermentation, the combustion in the combustion chamber 4 is stopped.

(5) When the combustion in the combustion chamber 4 is stopped, the atmosphere transfer device 3 switches to the intermittent operation.
By this intermittent operation, outside air containing oxygen necessary for fermentation is taken into the processing tank 1 from the outside air intake cylinder 14. (6) When the fermentation of the processed material in the processing tank 1 is almost completed, the processing tank 1 is heated to about 110 ° C. by the burner device 41 of the combustion chamber 4.
The fermentation product is adjusted to a water content (for example, 3 to 5%) suitable as a product such as fertilizer, and is taken out from the outlet 111 of the treatment tank 1. In addition, the water content is 10 to 1
When the content is 5% or less, the high-temperature aerobic fermentation bacterium becomes dormant, and the properties of the product hardly change. The present invention is not limited to the illustrated embodiment, but various modifications are possible within the scope of the claims.

[0017]

The present invention has the above configuration and has the following effects. (A) The odor generated from the processed material such as sludge and animal dung is transferred to the combustion chamber together with the atmosphere in the processing tank, burned, and deodorized. Further, during the operation of the atmosphere transfer device, the inside of the processing tank is at a negative pressure, so that the internal odor hardly leaks to the outside. Therefore, it is possible to prevent the odor from leaking to the outside of the apparatus and to improve the working environment.

(B) Even when the material to be treated has a large amount of water, by using the high-temperature aerobic fermentation bacterium, the treatment tank is heated to evaporate the water without killing the bacterium, and the amount of water suitable for fermentation is obtained. Can be adjusted quickly. Therefore, since the fermentation treatment can be performed quickly, it is possible to provide a fermentation treatment apparatus having an excellent treatment capacity.
