NOVELTY - An organic waste aerobic fermentation apparatus comprises a roller above a rolling ring-type support device and revolved on the support device, a drive device connected with the roller through a driving part to drive the roller to revolve, a feeding device, a tail gas recycling pipe, a water condenser, a fan, a heater, and a through hole gas distribution tube. The front and back ends of the rollers are provided with front and back seal housings for sealing the roller opening.    USE - An organic waste aerobic fermentation apparatus for an organic waste aerobic fermentation (claimed).    ADVANTAGE - The tail gas can be recycled in the roller to reduce the discharge of bad smell and ensure the material fermenting condition in the roller. The apparatus shortens the fermentation period and realizes the harmless disposal and recycling treatment of the organic waste, e.g. sludge, rubbish, and food waste.    DETAILED DESCRIPTION - An organic waste aerobic fermentation apparatus comprises a roller, front and back seal housings, a rolling ring-type support device, a drive device connected with the roller through a driving part to drive the roller to revolve, a feeding device, a tail gas recycling pipe, a water condenser, a fan, a heater, and a through hole gas distribution tube. The roller is arranged above the support device and revolved on the support device. The front and back ends of the rollers are provided with front and back seal housings for sealing the roller opening. The feeding device is arranged on the front seal housing. One end of the tail gas recycling pipe is communicated inside the roller through the back seal housing of the roller while the other end is connected with the through hole gas distribution tube through the water condenser, fan, and heater. The through hole gas distribution tube is extended inside the roller from the front seal housing of the roller.    DESCRIPTION OF DRAWING(S) - The drawing is a sectional view of an organic waste aerobic fermentation apparatus.
