NOVELTY - Roller type aerobic composting reactor comprises a main body (1), a main shaft (2), a machine frame (3), a motor (7), a speed reducer (6) and a transmission mechanism (5). The inner main body is set with an inner lining layer. The inner lining layer along the circumferential partition wall is uniformly divided into multiple mutually independent lining layer compartments, where each compartment are set with an air inlet branch pipe and discharge branch pipe. Each air inlet branch pipe and discharge branch pipe are connected to an air inlet grid rotating shaft and discharge gas rotating shaft.    USE - Used as roller type aerobic composting reactor.    ADVANTAGE - The roller type aerobic composting reactor: reduces water generated during composting process and refluxing of roller during stacking; and ensures uniform ventilation of the reactor and uniform composting, thus increasing quality of compost product.    DETAILED DESCRIPTION - Roller type aerobic composting reactor comprises a main body (1), a main shaft (2), a machine frame (3), a motor (7), a speed reducer (6) and a transmission mechanism (5). The inner main body is set with an inner lining layer. The inner lining layer along the circumferential partition wall is uniformly divided into multiple mutually independent lining layer compartments, where each compartment are set with an air inlet branch pipe and discharge branch pipe. Each air inlet branch pipe and discharge branch pipe are respectively connected to an air inlet grid rotating shaft and discharge gas rotating shaft through air inlet pipe and discharge pipe. Each of the air inlet pipe and discharge pipe are respectively provided with an intake valve and an exhaust valve. The air inlet valve and exhaust valve are respectively connected to a circuit through an air inlet valve limit switch and an exhaust valve limit switch. The upper front side plate of the rack is provided with a front baffle to control the air inlet valve limit switch. The upper rear side plate of the rack is provided with a rear baffle to control the exhaust valve limit switch.
