NOVELTY - Bio-type waste disposer, where a partition wall (1) is provided to divide a treatment tank (4) into a main tank (2) and a curing tank (3), is new. Several supply holes (6) are provided in the wall edge portion of the curing tank. A stirrer (7) with stirring bars (7c) perpendicular to the rotary shaft and scraping blades (7b) contacting inner wall surface of main and curing tanks and the partition wall, is provided in the treatment tank.    USE - For composting organic waste such as organic refuse.    ADVANTAGE - Favors composting process of organic refuse. Enables effective grinding of the organic waste. Enables removing only the compost which is fermented fully.    DETAILED DESCRIPTION - Bio-type waste disposer, where a partition wall (1) is provided to divide a treatment tank (4) into a main tank (2) and a curing tank (3), is new. Several supply holes (6) are provided in the wall edge portion of the curing tank. A stirrer (7) with stirring bars (7c) perpendicular to the rotary shaft and scraping blades (7b) contacting inner wall surface of main and curing tanks and the partition wall, is provided in the treatment tank. The supply hole (6) is positioned such that the scraping blades contact it during rotation of stirrer. An electric motor (8a) of the rotation drive unit (8) is attached to the rotary shaft to rotate the stirrer. A pair of inclined boards are provided above the wall of the treatment tank, to form the cover. A metallic net material (11) is arranged along the board. A dew-condensation water receiving slot (4c) is provided below the inclined board. A deodorization tank is included beside the treatment tank to remove the smell of the water formed by dew-condensation and discharged to the deodorization tank through a pipeline. The scraping blade is formed to triangular cross-section, which is arranged perpendicular to the rotary shaft.
