は、比較的高速、例えば分速１２メートル程度で行う。First, a water regulator such as sawdust is added to an organic waste (raw material) such as cattle and other livestock waste and kitchen waste such as garbage to produce a raw material having a water content of about 60%. It is thrown into the fermenter 60 by a shovel loader or the like, and is piled up about 1 to 2 meters. Then, the apparatus main body 10 is caused to travel to the stirring start position. The traveling at this time is performed at a relatively high speed, for example, about 12 meters per minute.

とを阻止できる。Further, since the rearward passage is prevented by the partition wall 40, there is an advantage that the raw material in the fermenter 60 can be prevented from escaping from the spiral blade 32 before being exposed on the surface. In particular, since the projecting portion 40a of the partition wall 40 is provided adjacent to the circular arc portion 33 on the rear side of the rotation trajectory of the spiral blade 32, it is possible to more reliably prevent the raw material from moving behind the spiral blade 32. .
