Wheat dryer is a mechanical equipment specially used for drying crops such as wheat. It plays a vital role in agricultural production. The following is a detailed introduction to wheat dryer:

1. Working principle

The working principle of wheat dryer is mainly based on hot air convection and moisture migration inside the material. Specifically, its working process includes the following steps:

Heating: The dryer heats the air to a certain temperature through a burner or an electric heater to generate hot air.

Convection: The heated hot air is blown into the dryer through the fan to exchange heat with the wheat. The hot air takes away the moisture on the surface of the wheat and causes the moisture inside the wheat to migrate to the surface.

Dehydration: With the continuous flow of hot air, the moisture on the surface of the wheat is continuously taken away, and the moisture inside the wheat gradually decreases to achieve the purpose of drying.

Dehumidification: The dryer is equipped with a dehumidification device to discharge the evaporated moisture to ensure that the humidity inside the dryer is controlled within a certain range.

Circulation: The hot and humid air generated during the drying process is discharged through the exhaust pipe, and then enters the heater for heating again after being cooled by the cooler to form a cycle, which can greatly improve the utilization rate of thermal energy.

Dingli wheat dryer adopts a multi-layer tower structure, and the hot air rises in the tower to dry the wheat. It occupies a small area and has high drying efficiency, which is especially suitable for large-scale production.
