The special working principle of the horizontal drying and cooling box

Drying principle: Hot air circulation is usually used to achieve the drying function. The equipment is equipped with a hot air system consisting of an air preheater, ventilation ducts, and a hot air blower. The hot air blower blows the preheated hot air into the drying box. The hot air is in full contact with the material, so that the moisture in the material evaporates, thereby achieving the purpose of drying.

Cooling principle: Cooling is performed through a cold air system. Generally, a cold air system is composed of a fan, a damper device, and an air outlet. The fan blows cold air from the air outlet into the drying box. The cold air exchanges heat with the dried material to reduce the material temperature and achieve cooling.
