FERMENTATION DEVICE

PROBLEM TO BE SOLVED: To provide a fermentation device capable of performing successful fermentation treatment of a material to be treated. SOLUTION: The fermentation device 20 works to microbially treat organic materials to be treated such as human excrements, feces of domesticated animals, and household garbage through fermentation. In addition, the device 20 is equipped with a fermentation tank 21 retained rotatably centering on an inclined rotary shaft, and a rotating mechanism 22 which rotates the fermentation tank 21. The fermentation tank 21 internally incorporates a fermentation chamber C for treating the material to be treated by fermentation, an outer shell part 23 formed symmetrically to the axis centering on the rotary shaft, a belt-like stirring blade part 24 which rises toward the center from the inner surface of the outer shell part 23 and extends in the rotary shaft direction, and an inner frame-like baffle plate part 25 with a surface formed orthogonally with the rotary shaft, rising toward the center from the inner surface of the outer shell part 23. The outer shell part 23 incorporates a receiving inlet 25A which is installed on the end part of the upper side in the rotary shaft direction and receives the material way into the fermentation chamber C and a discharge outlet 26A which is installed on the end part of the lower side in the rotary shaft direction and discharges the material which is through with fermentation treatment inside the fermentation chamber C.
