This type of equipment is commonly used in industrial production and is used to process various materials, such as chemicals, food, medicines, building materials, etc.

[0003] However, in the prior art, the drying kiln usually preheats the raw materials before starting formal drying to ensure that the temperature rises gradually to avoid adverse effects of sudden temperature changes on equipment and materials. The raw materials are mostly preheated by blowing hot air, but the angle of the hot air directly blown in is fixed, which will cause one side of the material to heat up too quickly and the heating is not uniform.
