NOVELTY - An organic waste decomposition device comprising plate shaped base frame; cylindrical shell casing to receive microorganism; shaft; arm blades to agitate and crush organic wastes; driving motor to provide force to shaft; ring blower to supply air into casing; air pipe to connect ring blower and lower portion of casing; pre-heater; condenser; steam pipe; cooling tank; and a control box, is new.    USE - The new device is used for decomposition of organic waste, e.g. food waste (claimed).    ADVANTAGE - The device comprises a deodorizing apparatus for effectively removing bad smells which occur during organic waste treatment. The device implements a high speed decomposition and does not need a secondary process with respect to remaining organic waste such as sludge. It is designed to be small and simple in its structure and is capable of implementing an easier operation and maintenance. The automatic cleaning system is capable of automatically processing a remaining substance after an organic waste decomposition is completed. The microorganism used for the organic waste decomposition operation is recycled therefore decreasing the cost.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) an organic waste decomposition device comprising:    (a) a plate shaped base frame;    (b) a cylindrical shell casing which is installed in the base frame (110) and receives a microorganism;    (c) a shaft that is rotatably installed in a center portion of the casing;    (d) arm blades which are engaged to the shaft and are adapted to agitate and crush the organic wastes;    (e) a driving motor (150) to provide a rotational force to the shaft;    (f) a ring blower (160) to supply air into the interior of the casing;    (g) an air pipe (170) that is adapted to connect the ring blower and a lower portion of the casing;    (h) a pre-heater (180) that is installed in the air pipe and is adapted to pre-heat the air supplied into the interior of the casing;    (i) a condenser (190) to liquefy a vapor discharged when an organic waste is decomposed in the interior of the casing and to discharged the liquefied vapor;    (j) a steam pipe (200) to connect an upper position of the casing and the condenser; and    (k) a control box (120) to control the operations of the driving motor, ring blower and pre-heater.    (2) an organic waste decomposition device, comprising:    (a) a fermentation tank which comprises an agitator capable of cutting an inputted organic waste and is adapted to decompose the organic wastes using an added microorganism bacteria and discharges a carbonic acid gas including water;    (b) a cooling tank which is adapted to cool a carbonic acid gas including water which occurs in the fermentation tank;    (c) a gas-liquid separator which is adapted to separate water and a carbonic acid gas flow in through the outlet pipe and to discharge the water through a first drainage pipe formed in the lower portion and in which the carbonic acid gas returns to the fermentation tank through the exhaust pipe formed in the upper portion; and    (d) a solid-liquid separator which is installed in the interior of the cooling tank and is adapted to filter a sludge from the water flown in through the first exhaust pipe and discharge through the second exhaust pipe connected to an outlet.    (3) an automatic cleaning device of an organic waste decomposition device comprising:    (a) a hopper connected with a fermentation tank of an organic waste decomposition device using a suction line and is adapted to suck a remaining substance from the fermentation tank and store it;    (b) a twist screen to filter a remaining substance supplied from the hopper and separates the substance into a recyclable substance and a non-recyclable substance and discharge the substance;    (c) an eject hopper to store a recyclable substance separated and discharged from the twist screen;    (d) a cyclone connected with the eject hopper by a pressure line and adapted to re-supply a recycled substance from the eject hopper to a fermentation tank to return a part of the same to the hopper; and    (e) a ring blower to suck air from the hopper, thus implementing a decreased pressure state in the interior of the hopper and to generate a certain air pressure for transferring a recyclable substance from the hopper to the cyclone.
