According to the relative movement direction of grains and airflow, corn dryers can be divided into many types, such as cross-flow dryers, mixed-flow dryers, and downstream dryers. Each type has its own unique characteristics and applicable scenarios:

Cross-flow dryer: simple manufacturing process, easy installation, low cost, and high productivity. However, the grain drying uniformity is poor, the unit heat consumption is high, and one machine is limited to drying multiple grains.

Mixed-flow dryer: The hot air supply is uniform, and the moisture content of the grain after drying is relatively uniform; the unit heat consumption is low, the fan power required is small, and the unit consumption of the drying medium is also small; the variety of grains dried is wide, and it can dry both grains and seeds; it is easy to clean and not easy to mix seeds. But the structure is complex and the manufacturing cost is slightly high.

Downstream dryer: The hot air temperature is high, the unit heat consumption is low, and the quality of the grain after drying can be guaranteed; the precipitation range is large during continuous drying. But the structure is relatively complex, the manufacturing cost is high, the required high-pressure fan power is large, and the price is high.

Use and maintenance of corn drying machine

When using the corn dryer, you need to follow the correct operating steps, including connecting the power supply, testing the fan, loading, igniting, controlling the temperature, turning the corn and discharging. At the same time, you also need to pay attention to the maintenance and care of the dryer, such as regularly cleaning the residues in the drying room, checking the operation of the hot air furnace and exhaust system, etc.

Dingli grain dryer has a wide range of applications and can be used to dry rice, wheat, barley, soybeans, corn and other grains. Please consult us if you need.
