NOVELTY - The temperature and humidity are maintained at fixed range inside a fermenter (40). The ground organic refuse and deodorization biomicrobe are thrown in the fermenter. A blade provided in fermenter stirs the organic refuse for fixed period of one day such that primary fermentation of the refuse is carried out. DETAILED DESCRIPTION - The bacteria supplied in the fermenter is natural bacteria which is rubbed and adhered in the fermenter. The stirring process is performed for long time, so organic refuse moves along fixed direction. The direction of stirring is reversed for fixed period. An INDEPENDENT CLAIM is also included for organic refuse processing apparatus in which a sensor is provided in the apparatus to detect the temperature and humidity of fermenter which possesses bacteria. An adjusting unit maintains arbitrary ranges of temperature and humidity in fermenter, based on detected value of sensor. The compressor carries out release of air from nozzle which is provided in fermenter. An exhaust unit (70) is provided in the apparatus to eject air from fermenter. An actuation unit is provided to rotate the blade. A control unit is provided in the apparatus to control operation of blade for fixed period of one day and also to control operation of blade to normal or reverse rotation for fixed period. An injection unit (20) is provided to throw deodorization biomicrobe in the fermenter. The control unit controls the operation of the injection unit. Rotatable U-shaped feathers are provided to both end walls of fermenter radially. The microangle of feather is twisted. The rotation axis of feather is attached along fixed and extended direction of blade rotation axis. An opening (23) is provided for the supply of organic refuse to fermenter. A cover (22) is used to close the opening. An input unit receives code number input and compares with registered code number and if the values agree, the cover is opened wide by an opening control unit. The injection of organic refuse is continued in the fermenter. The organic refuse supplied from opening is ground by a grinder (30) before supplying to the fermenter.    USE -   For waste rubbish.    ADVANTAGE -   The volume of organic refuse is reduced extremely due to stirring of organic refuse for long period. The smell of organic refuse during processing does not occur, therefore organic refuse processing method is performed in home also. DESCRIPTION OF DRAWING(S) - The figure shows the front elevation of organic refuse processing apparatus.
