NOVELTY - Domestic garbage and/or kitchen garbage fast aerobic fermentation device comprises cylindrical or rectangular multi-layered fermenting chamber (39), air heater (14), feeder (6), blower (13), water storage tank (15) and gas purifier (35). The multiple-layered fermenting chamber is provided with feeding port (8), artificial feeding port (33) equipped with airtight cover (32), and gas outlet (31) connected with inlet valve (34) and valve (5). Thermometers or temperature detectors (3) are respectively arranged on fermentation layers (2,22,23,26).    USE - A domestic garbage and/or kitchen garbage fast aerobic fermentation device.    ADVANTAGE - The device improves utilization rate of aerobic air, accelerates decomposition and fermentation speed of material, occupies small area, reduces fermentation cost, shortens fermentation time and improves unit volume yield.    DETAILED DESCRIPTION - Domestic garbage and/or kitchen garbage fast aerobic fermentation device comprises cylindrical or rectangular multi-layered fermenting chamber (39), air heater (14), feeder (6), blower (13), water storage tank (15) and gas purifier (35). The multiple-layered fermenting chamber is provided with feeding port (8), artificial feeding port (33) equipped with airtight cover (32), and gas outlet (31) connected with inlet valve (34) and valve (5). The gas outlet is connected to gas purifier. The blower is connected to air heater. The air heater is connected to multi-layered fermenting chamber through valves (7,11,37). Thermometers or temperature detectors (3) are respectively arranged on fermentation layers (2,22,23,26). A controller (10) is connected to air heater and blower. The fermenting chamber is connected to water storage tank through discharge port (17) which is equipped with valve (16). The multiple-layered fermenting chamber is also provided with spiral discharging device (21) which is set with fermentation material outlet (20). The material outlet is connected with outlet valve (19).
