NOVELTY - A fermentation equipment comprises four parts comprising an atmospheric ventilation system, a drainage system, a delivery system, and a fermentation chamber. The fermentation chamber is parted by a supporting material that maintains hydrostability and is thermal insulated and water-proof. The atmospheric ventilation system comprises air inlet hole, air outlet hole and exhaust funnel. A vertical venting slit or venting hole is installed at the place where the main body of fermenting materials is stored. The venting slit is formed by double layered gridding frame (8).    USE - Fermentation equipment.    ADVANTAGE - The fermentation equipment is easy to assemble and low in cost, avoids upending of fermenting materials, and makes fermentation faster and better.    DETAILED DESCRIPTION - A fermentation equipment comprises four parts comprising an atmospheric ventilation system, a drainage system, a delivery system, and a fermentation chamber. The fermentation chamber is parted by a supporting material that maintains hydrostability and is thermal insulated and water-proof. The fermentation chamber is also installed with two separate doors or one single door for materials to enter or exit. The atmospheric ventilation system comprises air inlet hole, air outlet hole and exhaust funnel. A vertical venting slit or venting hole is installed at the place where the main body of fermenting materials is stored. The venting slit is formed by double layered gridding frame (8) while the venting hole is a central hollow part of the gridding pillar or formed by pokes of furnace poking stick. The drainage system uses the exhaust funnel as passage for both air and water drainage, and is optionally installed with water tank, drainage ditch, watering wall and arch or sloped watering ceiling. The exhaust funnel sits on exhaust funnel base plate. The base plate is narrowed with diameter of 1-2 cm on top. There are more than 5 uniformly spaced drainage ditches surround the base plate, each of which has depth of 0.2-0.5 cm so that water condensed on the exhaust funnel is expired along the path. The water content of a fermentation material is controlled to 30-70%, and is placed into a fermenting frame after it is uniformly mixed, where temperature reaches over 60 degrees C after 24-72 hours of fermenting, and maintaining this temperature for 24 hours kills bacteria, pests, and pest ovum, discomposes pesticide residues, and removes toxicity from agricultural ecosystem. The fermented material can be used as substrate material for chicken raising, hog raising and fermentation bed cultivation, or as direct cultivation material for Pleurotus ostreatus, Pleurotus pulmonarius and Lentinus edodes to be fermented for 8-10 more days. The material can also be used as direct cultivation material for soil saprophytic mushrooms such as Coprinus comatus, Agaricus bisporus and Agaricus blazei to be fermented for 15-20 days. The material can further be used as semi-matured organic manure to be inoculated with functional bacterial strain for 15-20 days to produce biotic organic manure. The material can be added with inorganic nutrients to produce fertilizer with high bioavailability.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a ventilation system.
