DETAILED DESCRIPTION - The device comprises a hollow cylinder body, a fermentation system, a monitoring system, a steam sterilizing system, a ventilation system, a heat preservation system, a deodorization system, an auxiliary tool, a fermentation room, a sampling port, a discharge hole, inner and outer cylinders, an insulating layer, a heat preservation cover, a feeding port, a lamp, a leachate system, a measuring perspective holes, a wheel, and a fixing unit. The fermentation system and monitoring system are connected by a monitoring computer and a printer for reading, storage, management and printing process. The discharge hole is opened at the fermentation room and ended at the bottom of the discharging port. The heat insulation cover is made of cotton. The monitoring system includes humidity gas sensor, temperature pressure sensor, a converter and a computer. The humidity gas sensor and temperature pressure sensor holes are opened at the heat preservation cover. The converter and sensors are connected to the computer. The steam sterilizing system comprises steam generator, a gas pipeline, a gas room, a porous plate, a porous plate pull ring and an air outlet pipeline. The steam generator is connected with a distribution pipeline, which passes through the outer and inner cylinders entering into the gas distribution room. The ventilation system includes an air compressor, an air storage tank, a time controller, a temperature controller, a pressure controller and a flow meter. The pipeline, the gas room, the porous plate, the porous plate pull ring, the air outlet pipeline, the air compressor, and the air storage tank are connected with the time controller, temperature and pressure controllers and the flow meter. The controller is connected with the distribution pipeline. The leachate system comprises a collecting room, a filter porous plate, a slope surface and a drain. The heat preservation system includes a sampling port, a seal insulating plug, a discharge hole for seal insulating plug, inner and outer cylinders, the insulating layer, the heat preservation cover, perspective holes and a filler connecting the outlet pipeline. The tool comprises a discharging scraping rake, a sampling tube and a porous plate. The outer cylinder has a length of 1220 mm and the inner cylinder has a length of 500 mm. The cylinders have thickness of 50 mm. The porous plate has a pore diameter of 5 mm, 6 mm or 8 mm. The inner cylinder is made of polypropylene material. The heat preservation layer is made of heat insulating cotton. The outer cylinder is made of stainless steel material. An INDEPENDENT CLAIM is included for fermenting the waste vegetable material using the device.
