<p>PROBLEM TO BE SOLVED: To provide a compost-mixing machine for the fermentation treatments of various waste fluids, sludge, livestock excreta, starch pulp, etc. SOLUTION: This compost-mixing machine is obtained by attaching two vertical screws 4 also in the backward movement directions of chain cases attached on both sides of a main rotor to freely permit a forward spraying and stirring operation and a backward spraying and stirring operation. Since the forward spraying and stirring operation and the backward spraying and stirring operation can be carried out using the totally four vertical screws, the water content of the compost can uniformly be controlled in the whole portion of the tank, and the compost can evenly be stirred and mixed. Thereby, a perfect high temperature fermentation can efficiently be maintained for a long period, and a large amount of the composting material can be treated.</p> |
