The grain dryer is used for drying grain crops such as wheat, corn, rice, beans and so on. Users can choose dryers of different capacities according to the scale of agricultural production and the amount of grain drying.
The drum dryer can use coal, rice husk or straw etc as fuel, and convert it into clean hot air through combustion and heat exchange, which does not pollute the dried grain. It can use the gas to heat
Performance characteristics of the dryer: The grain discharge device of the grain dryer adopts a sliding valve structure, which does not damage the material during operation, and the grain discharge speed can be adjusted by frequency conversion according to the output and water removal requirements. To meet the requirements of grain or commercial grain, adjust the drying speed to meet the quality requirements.
There is no power flow of fuel in the dryer equipment, the operation is simple and the floor space is small. The materials pass through the diversified drying areas to achieve continuous, gentle and uniform moisture and heat exchange. Using automatic control, the residence time of materials in the tower can be adjusted at will. Through the air flow control and the movement of the processed product, the processed product can be dried evenly and thoroughly. The tower dryer is most suitable for slow and even drying.
During the drying process of materials, there are hot air flow and radiant heat energy. Hot air drying means that the hot air flow moves forward from the tail to fully contact the material. Through heat conduction, the radiant heat energy is fully utilized, and the heat energy is fully transferred to the material to make the material The water in the cylinder is continuously evaporated, and the air-inducing device at the discharge port draws out a large amount of water and humidity to prevent secondary pollution caused by dust discharge.
