<p>PROBLEM TO BE SOLVED: To provide an org. waste treating device by which the dehumidifying function is not deteriorated unlike the conventional one wherein the vapor generated in the aerobic fermentation of a waste is circulated between a treating tank and a dehumidifier, the resulting fine powder is deposited in a circulating line to close the line, hence the dehumidifying function is deteriorated, slag is formed in the treating tank due to the low dehumidification, and the vapor is sucked into a blower for supplying oxygen into the tank to cause the defective insulation of a motor, corrosion of the blower and production of noises. SOLUTION: A dehumidifying heat-exchange means 70 is provided in a treating tank 50 or above the tank, the vapor is circulated between a dehumidifying heat-exchange means 75 and the treating tank 50 by natural convection, the whirling up of a fine powder is prevented, and a circulating fan and an air duct are dispensed with. Meanwhile, the air (exhaust pipe) 80 on the suction side of an air replacing blower 86 is exposed to the external air and transiently cooled, the moisture is separated by a gas-liq. separator 81, then the air is brought into contact with the wall of the tank 50 and reheated, and dry air is obtained. The troubles of the blower 80 due to the infiltration of water are eliminated in this way.</p> |
