NOVELTY - Organic refuse, pulverized in grinding apparatus (1) is stored in reserve a tank (1g) and forced into an adjustment tank (2) via a slurry pipe (3) with the same volume as the reserve tank. Water is supplied into tank (1g) from water supply hole (9) and water from tank (1g) is forcefully supplied into tank (2) via pipe (3), such that pulverized refuse remaining in pipe is washed by water.    USE - The organic refuse processing apparatus is used for processing domestic refuse from home, school, hospital and restaurant.    ADVANTAGE - Residual salt classification of the compost is not required. Dehydration and desalination of the compost is performed using a simple apparatus and good quality fertilizer can be obtained from the compost. The organic refuse does not remain in the slurry pipe except during forced supply, thereby, preventing the jamming of slurry pipe. The slurry pipe is always maintained clean, thereby preventing the generation of bad odor as refuse remaining in the pipe is washed by forcefully supplying water.    DETAILED DESCRIPTION - Organic refuse pulverized in organic refuse grinding apparatus (1) is forcefully supplied into reserve tank (1g) by pump (1i) where it is stored and then supplied into adjustment tank (2) via slurry pipe (3) which has same volume as that of reserve tank. Water is supplied into tank (1g) from water supply hole (9) and water from tank (1g) is supplied with pressure into tank (2) via pipe (3), such that pulverized refuse remaining in pipe is washed by water.    An INDEPENDENT CLAIM is also included for washing apparatus of slurry pipe in compost processing apparatus. The apparatus has an organic refuse injection hopper in which organic refuse is supplied and cutter which grinds supplied organic refuse. A water supply shower supplies water and slurries water and pulverized refuse and the slurry is stored in the reserve tank. A pump (1i) is provided for forcefully supplying refuse into the reserve tank and a slurry pipe connects refuse tank and adjustment tank. The slurry pipe supplies refuse and water from reserve tank with pressure into adjustment tank.    DESCRIPTION OF DRAWING(S) - The figure shows explanatory drawing of compost processing apparatus.
