Block grain dryer PP036
The main characteristics, the essence of the development
The flue gases enter the flue 1 with the evaporator of the thermosyphon (TS). Condensation TS areas of the vehicle are placed in the ball heaters of grain 2. In the heater with TS 4, the air is heated to the temperature of the drying agent supplied to the drying shaft 3. In the block dryer, 42 % of the coolant is not released into the environment, but recycled. It reduces energy losses with the spent coolant. To grain energy is supplied through the vehicle. This ensures environmental safety drying, uniform supply of energy to the grain and its efficient mixing. Block efficiency of the dryer compared to the baseline scheme increases by 20 - 22 % .
· productivity at drying of wheat (from 20 to 14 % ) - 6 t/h;
· consumption: fuel - 5. 24 kg/t; energy - 3. 5 - 3. 7 MJ/kg of moisture;
· thermal efficiency - 60 % ;
· coolant - heated clean air.
