Tower grain dryers absorbing the advantageous technique of foreign advanced models, are designed and manufactured based on our years of experience and local conditions. The machine is very adaptable to different grains and surroundings, which can be used for drying rice, soybean, wheat, sorghum, rapeseed, corn, and oil crops. The grain drying machine uses clean hot air as a heat medium, in other words, hot air drying. The heat source is a coal hot air furnace or oil hot air furnace. This drying machine can realize continuous drying operation and outdoor installation, which is suitable for the grain storage and grain and oil processing factories.

 Put the Grain into the dryer in batches then circulate orderly by the interaction of electric parts and structural parts. The hot air from the hot air furnace gets into the mixed-flow drying layer to across and heat the grain under the action of two Draft fans. The air flows and takes off the moisture of the grain, then the exhaust gas is excluded out of the machine by the exhaust fan when the moisture reaching to the set value, the machine stops working.

Furnace Working Principle:

  Put the fuels, such as rice hull, straw, and anthracite into the furnace to burn, then to generate heat. The smoke gets into the heat exchanger and discharges outside after many cycles. At the same time, the cold air is heated up through the heat exchanger outside and then discharged out of the dryer. It can increase thermal efficiency, save energy, and reduce costs greatly.
