A dryer is a mechanical device that uses heat to reduce the moisture of a material and is used to dry the object. The dryer vaporizes the moisture (usually referred to as moisture or other volatile liquid components) in the material by heating to obtain a solid material having a specified moisture content. The purpose of drying is for the purpose of material use or further processing. For example, the drying of the wood before the production of the wood mold and the wood can prevent the deformation of the product, and the drying of the ceramic material before the calcination can prevent the product from cracking. In addition, the dried material is also convenient for transportation and storage, such as drying the harvested food to a certain moisture content to prevent mildew. Since natural drying is far from meeting the needs of production development, various mechanized dryers are becoming more and more widely used. The drying process requires a large amount of heat energy. In order to save energy, some materials with high moisture content, suspensions or solutions containing solid substances are generally first mechanically dehydrated or heated to evaporate, and then dried in a dryer to obtain a dry solid. In the drying process, heat and mass (moisture) transfer must be completed at the same time to ensure that the moisture partial pressure (concentration) of the surface of the material is higher than the moisture partial pressure in the external space to ensure that the heat source temperature is higher than the material temperature. Heat is transferred from the high-temperature heat source to the wet material in various ways, so that the surface of the material is vaporized and vaporized to the external space, so that the difference in moisture content occurs on the surface and inside of the material. The internal moisture distribution diffuses and vaporizes to the surface, so that the moisture content of the material is continuously reduced, and the overall drying of the material is gradually completed.
