<p><P>PROBLEM TO BE SOLVED: To make the facilities for progressing composting treatment compact, to improve the sanitation therein and to enhance the efficiency in composting work in actual operations. <P>SOLUTION: Compost raw materials and auxiliary materials weighed per material and charged from a receiving hopper are individually stored in a material receiving part 10. The compost raw materials and auxiliary materials fed from the material receiving part 10 to a mixing tank 20 are mixed by a stirring mechanism 21 to obtain a compost material. Next, the compost material is fed from the mixing tank 20 to the starting end of a storage fermentation path 33 in a primary fermentation tank 30. The compost material is transferred in the longitudinal direction of the storage fermentation path 33 in the prescribed number of days and is turned so as to cause the primary fermentation of compost by the activation of aerobic microorganisms. Further, the compost which has reached the end of the primary fermentation and discharged from the termination part of the primary fermentation tank 30 is stored per prescribed quantity in a plurality of humidity-controllable containers 41 which are individually movably arranged. While the individual containers 41 move to the termination part in succession, turning is performed per container 41, and the maturing fermentation (secondary fermentation) of the compost is carried out at the inside of each container. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
