INSTALLATION FOR COOLING, CONSERVING AND DRYING SEEDS IN ACTIVE-VENTILATION HOPPERS Russian patent published in 2003 - IPC

FIELD: drying processes and equipment, possibly cooling, conserving and drying seeds of agricultural crops. SUBSTANCE: installation includes thermoconversion system having evaporator, condenser and compressor, drying and cooled hoppers, blower supplying air through condenser to drying hoppers and blower supplying air through evaporator to cooled hoppers. Hoppers are provided with shelters. Air ducts are formed between shelters and outer walls of hoppers. Exhaust branch pipe of each drying hopper is connected with suction side of cooled hoppers blower. The last is connected by means of delivery branch pipe through evaporator with inlet of cooled hoppers. Exhaust branch pipe of each cooled hopper is connected with suction side of drying hoppers blower. The last is connected by means of delivery branch pipe through condenser with inlet of drying hoppers. Delivery branch pipe of blower of drying hoppers is connected after condenser with suction side of blower of cooled hoppers. Delivery branch pipe of blower of cooled hoppers after evaporator is connected with suction side of blower of drying hoppers. Connecting air ducts are provided with valves. Air ducts connecting exhaust side of hoppers with suction side of blowers and air ducts connecting hopper inlets with condenser and with evaporator are provided (at both sides of valve) with branch pipes communicating with atmosphere and having valves. Thermoconversion system is reversible one. EFFECT: enhanced efficiency of installation. 1 dwg
