NOVELTY - An rolling type aerobic fermentation device with heat exchanger comprises horizontal cylindrical fermentation tank (6) supported by wheels, where left and right ends of the tank are respectively provided with bearings having an outer ring (5) and an inner ring (4) and left (3) and right (12) side covers respectively installed on the inner ring of the bearing in the middle to form a sealed chamber. It further comprises a spiral feeding machine (1), an exhaust pipe (2), spiral discharging machine (16) and air inlet pipe (13) installed on the left and right side cover.    USE - As a rolling type aerobic fermentation device (claimed) useful for treating sewage, sludge and garbage and preparing organic fertilizer.    ADVANTAGE - The laying cylinder rolling type aerobic ferment device is not influenced by environment factor and low temperature condition; has high fermentation efficiency; does not generate secondary pollution; doesn't provides bad smell and heat; and provides good environment protection effect.    DETAILED DESCRIPTION - A rolling type aerobic fermentation device with heat exchanger comprises horizontal cylindrical fermentation tank (6) supported by wheels, where left and right ends of the tank are respectively provided with bearings having an outer ring (5) and an inner ring (4) and left side cover (3) and right side cover (12), respectively installed on the inner ring of the bearing in the middle to form a sealed chamber.
