NOVELTY - An organic waste processing apparatus comprises a mount frame (6) having a trolley (7) installed to be horizontally movable to the upper part of a fermentation processing tank (2) which stores organic waste (S). A stirring grinding apparatus (3) for the organic waste is suspended down to the trolley. The fermentation processing tank is formed in a cylindrical shape so the upper surface releases. The mount frame is rotationally moved on the processing tank.    USE - For carrying out fermentation processing and for composting agricultural waste material, livestock farming excretion, agricultural colony wastewater sludge, sewage sludge, foodstuff waste material, fishery waste material, and wood-type waste material.    ADVANTAGE - The organic waste processing apparatus is suitable also for small-scale composting building. While garbage deposited on fermentation processing tank lower part is stirred by operating screw, it is pumped in casing after waste material injection. Part of the organic refuse is ground by extruding from the hole formed in the casing wall during pumping. The garbage which reached the top open part of the casing is extruded from an open part circumference. The organic refuse extruded from the hole and the top open part circumference will be in dispersion state. It falls in a fermenter processing layer. Transpiration of grinding and stirring with a sufficient organic refuse and water content is performed in the process. Water content, oxygen concentration and size are adjusted moderately. The optimal fermentation processing conditions by microorganisms are acquired. A fermentation processing is performed efficiently.
