NOVELTY - The organic waste processing device comprises an inner cylindrical tank body and an outer cylindrical tank body arranged in an interval to form an aerobic fermentation chamber area. A hollow tube rotating shaft is rotatably mounted in the outer tank body, and passes through the inner tank body. A stirring bracket is arranged in a U-shaped cavity of the inner tank body, and includes a through hole. The hollow tube rotating shaft is connected with a lower side part of the stirring bracket. A hollow type lower stirring pole is connected with a through hole of the inner tank body.    USE - Organic waste processing device.    ADVANTAGE - The device: is novel in design, compact in structure, energy-saving, and convenient and reliable to use; has increased service life; and efficiently processes the organic waste with improved quality.    DETAILED DESCRIPTION - The organic waste processing device comprises an inner cylindrical tank body and an outer cylindrical tank body arranged in an interval to form an aerobic fermentation chamber area. A hollow tube rotating shaft is rotatably mounted on the outer tank body in an axial position, and passes through the inner tank body. A stirring bracket is arranged in a U-shaped cavity of the inner tank body, and includes a through hole. The hollow tube rotating shaft is connected to a lower part of the stirring bracket. A hollow type lower stirring pole is connected to the through hole of the inner tank body. A plate is assembled on an outer part of the hollow lower stirring pole. A stirring tooth is fixed at the inner tank body. A spiral tube-type heating water jacket is fastened on the inner tank body. A closed pull plate is arranged in a lower part of the inner tank body. A material discharging device is connected to an outer side of the outer cylinder. A power input shaft, a speed reducer and a power output shaft are connected with a motor and the hollow tube rotating shaft. An air supply tube and a gas pump are connected with the hollow tube rotating shaft. A hot water output tube of a solar energy water heater is connected with the spiral tube-type heating water jacket. A liquid pump of a cold water return tube is connected with a water return port of the solar energy water heater. A gas tube is connected with a marsh gas collecting device.
