NOVELTY - The rotating type kitchen garbage biochemical treatment device with an exhaust system comprises a substrate, a roller supporting seat mounted on the substrate, a roller (30) rotationally mounted on the roller supporting seat, a rotating control part for controlling the rotating and stopping of the roller, an air inlet-outlet system comprising an air inlet device (50A) and an exhaust device, and a post-treatment device. The roller comprises an opening, an inner space, a hollow air through shaft and an air guide port (34). The kitchen garbage enters the inner space through the opening.    USE - The device is useful for biochemical treatment of rotating type kitchen garbage with an exhaust system.    ADVANTAGE - The device ensures efficient and easy biochemical treatment of rotating type kitchen garbage with less power consumption, and allows uniform fermentation of kitchen garbage without affecting the intake and exhaust systems.    DETAILED DESCRIPTION - The rotating type kitchen garbage biochemical treatment device with an exhaust system comprises a substrate, a roller supporting seat mounted on the substrate, a roller (30) rotationally mounted on the roller supporting seat, a rotating control part for controlling the rotating and stopping of the roller, an air inlet-outlet system comprising an air inlet device (50A) and an exhaust device, and a post-treatment device. The roller comprises an opening, an inner space, a hollow air through shaft and an air guide port (34). The kitchen garbage enters the inner space through the opening. The air inlet device is connected with the hollow air through shaft. The exhaust device is connected with the air guide port. The rotating control part comprises a power source, and a power transmission subassembly connected with the power source and the hollow air through shaft to transmit the roller to rotate through the power source. The air inlet device comprises an air inlet, an air inlet machine and an air inlet conduit. The air inlet machine extracts the air through the air inlet. The air inlet conduit is connected with the air inlet machine and the hollow air through shaft. The exhaust device comprises an exhaust conduit, an exhaust machine, an exhaust opening, and an opening end cover. The exhaust conduit is connected with the air guide port and the exhaust machine. The air is pumped out of the inner space by the exhaust machine. The exhaust opening discharges the air out of the exhaust machine. The opening end cover is configured for sealing the opening. The air inlet device is fixed on the substrate and connected with the hollow air through shaft. The hollow air through shaft is configured for rotating along the rotating cylinder. The exhaust device is fixed on the substrate and connected with the air guide port. The air guide port is configured for rotating along the roller. The roller supporting seat is provided with a front pivoting part and a back pivoting part so as to rotationally mount the air guide port of the roller and the hollow air through shaft. The post-treatment device is connected with the exhaust opening.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of a rotating type kitchen garbage biochemical treatment device.
