<p>PURPOSE:To accelerate more compositing, by providing plural agitators and plural propellers to a driving shaft provided longitudinally in a fermentation tank and contituting the propellers so as to differ in the propelling direction thereof on the right and left sides of the driving shaft. CONSTITUTION:The org. waste material charged into a fermentation tank 1 by the normal and reverse rotation of a driving shaft 2 is agitated, moved and mixed continuously by agitators 3 and propellers 4 under introduction of air from the outside so that fermentation and drying are progressed while the org. waste material in the tank is maintained at a uniform level. Each small amt. of the moist raw material, i.e., org. waste, is charged from the raw material feed sections 5 provided in both end parts of the tank 1 while the high temp. state is maintained over the entire part of the sludge in the tank by the heat of fermentation generated in this stage. The org. waste is discharged from a discharge section 6 provided in the central part of the tank 1 by as much as the amt. conforming to the amt. of the waste material charged into the tank. The moisture content of the org. material to be first discharged into the tank 1 is adequately about 35%.</p> |
