NOVELTY - The solid-state fermentation system comprises a screw device for mixing organic waste, a fermenter, a carrier for conveying crushed organic waste to the screw device, a discharging device for discharging the waste, an exhaust system, a control portion for controlling solid-state fermentation, a sensing unit for sensing viscosity, temperature, pressure, particle size and moisture content of the organic waste, a mobile device, and a delivery device. The control portion further controls: the data obtained in the screw device; and the movement of the mobile device.    USE - The solid-state fermentation system is useful for fermenting organic waste including wastewater sludge, food waste and livestock excretion in residential area and civil applications.    ADVANTAGE - The system efficiently ferments the organic waste with high-capacity and quality in an eco-friendly manner.    DETAILED DESCRIPTION - The solid-state fermentation system comprises a screw device for mixing organic waste, a fermenter, a carrier for conveying crushed organic waste to the screw device, a discharging device for discharging the waste, an exhaust system, a control portion for controlling solid-state fermentation, a sensing unit for sensing viscosity, temperature, pressure, particle size and moisture content of the organic waste, a mobile device, and a delivery device. The control portion further controls: the data obtained in the screw device; and the movement of the mobile device. The screw device and the discharge device are provided with a fermentation vessel along a first direction. The first direction is perpendicular to a second direction. The first and second directions are perpendicular to a third direction. The mobile device moves the organic waste within the vessel along the third direction. The mobile device comprises a hydraulic motor and a hydraulic cylinder. A rotation controller controls the rotating speed of the exhaust system. A movement controller controls the transition speed of the exhaust system. A first screw body is seated toward a center of the screw device. The screw body is positioned on a backside of a first wing. The delivery device is a conveyor belt. The discharging device is rotated under control of a control section of a second screw body. The second screw body is mounted on the delivery device for transporting along longitudinal direction. A second wing provided with a screw.
