NOVELTY - Compost fermenter comprises a blade which is easily disassembled and assembled. The blade is provided with a bottom plate installed horizontally, a front sloping plate coupled with front end of bottom plate, a rear sloping plate inclinedly installed and coupled with rear end of front sloping plate, a rear supporting plate formed with supplying ports coupled between rear end of rear sloping plate and bottom plate, a vertical reinforcing stand formed with holes, a horizontal reinforcing stand for reinforcing upper portion of bottom plate, and a supply protector installed on rear sloping plate.    USE - Used as compost fermenter.    ADVANTAGE - The fermenter reinforces strength of the rotating shaft by avoiding direct application of load on the rotating shaft, is economical, supplies air according to density of the compost, enables the blade to withstand larger weight and pressure, and prevents clogging of the holes of the supplying port.    DETAILED DESCRIPTION - Compost fermenter comprises a blade (26) which is easily disassembled and assembled. The blade is provided with a planar bottom plate which is installed horizontally, a planar front sloping plate inclinedly installed at a constant angle from the front end and coupled with the front end of the bottom plate, a planar rear sloping plate inclinedly installed and coupled with the rear end of the front sloping plate, a rear supporting plate formed with supplying ports at regular intervals along the rear longitudinal direction and coupled between the rear end of the rear sloping plate and the bottom plate, a vertical reinforcing stand equidistantly formed with holes along the longitudinal direction on an intermediate height portion and vertically installed between the rear end of the bottom plate and the front sloping plate, a horizontal reinforcing stand for reinforcing the upper portion of the bottom plate, and a supply protector fixedly installed on the rear sloping plate along the longitudinal direction on the rear end portion of the rear sloping plate. The fermenter produces compost by introducing drum-shaped shell (10) into organic waste, stirring the organic waste through rotating the blade coupled to a rotating shaft (25), and fermenting. The blades are vertically installed in 4-5 in numbers with the rotating shaft along the rotational axis.
