[0002] Air drying refers to drying by wind. Existing air drying devices are usually used in conjunction with heat pump units. The heat pump unit sends dry hot air to the heat pump drying box to dry the materials inside.

The fan drives air to flow through the heat pump system to dry the materials on the shelf. When the drying box is long, the materials on the shelf close to the fan and the materials on the shelf far from the fan are prone to uneven drying, which affects the drying quality of the materials.
