NOVELTY - A vertical fermentation cabin comprises cabin walls (1), cabin top (2), suction opening, material inlet (3), material outlet (4), beam (5), hydraulic system (6), belt transmitting system (7) and gas offering system (8).    USE - As vertical fermentation cabin; and for fermenting process which is the multi-grade fermenting process (claimed).    ADVANTAGE - The vertical fermentation cabin reduces the weight of the material which falls from the top; avoids the anoxia for pile body of oxygen for compressed material; has low maintaining cost. The process is easily controlled; has short fermentation period; and has stable quality product.    DETAILED DESCRIPTION - A vertical fermentation cabin comprises cabin walls (1), cabin top (2), suction opening, material inlet (3), material outlet (4), beam (5), hydraulic system (6), belt transmitting system (7) and gas offering system (8). The beams are distributed on the perpendicular bisector between the material inlet and the material outlet. The material inlet is opened at the middle of the top of the fermentation cabin. The suction opening is opened beside the material inlet. The material outlet is opened at the middle of the bottom of the fermentation cabin. Two sides of the material outlet are the gaps, filled with the stone blocks. The upper part of the block is the hydraulic system and the movable scraper blade driven by the hydraulic system. The belt transmitting system is located below the material outlet. The gas offering systems are respectively arranged in the gaps, below the beam and beside the cabin walls. An INDEPENDENT CLAIM is included for fermenting process for the vertical fermentation cabin involving preparing the material, adding certain amount of assistant in the livestock and poultry dung, adjusting the humidity of the organic material, the water content is 50% for fermenting and lifting conveniently; inoculating, adding strain in the prepared organic material, inoculating for 1% of the total weight of the material, the strain is the compound strain of the yeast, Bacillus megatherium and lactic acid bacteria, mixing evenly; lifting, lifting the organic material evenly mixed to the top layer of the fermentation tower; fermenting each fermentation cabin for 2-4 days, after getting to the fermentation days, transferring the material to the other fermentation cabin and fermenting, fermenting the fresh material into the semi-finished product and the whole period is 8-12 days; material discharging: driving via the hydraulic system, removing the organic matter downwards to the material discharge port, where the hydraulic system is combined with the scraper blade for discharging the material.    DESCRIPTION OF DRAWING(S) - The figure shows a view of vertical ferment storehouse air outlet structure.    Storehouse wall (1)    Top drive (2)    Feed inlet (3)    Discharge hole (4)    Beam (5)    Hydraulic system (6)    Belt conveying system (7)    Air supply system (8)
