Background
Drying equipment is also known as dryers and dryers. The apparatus for carrying out the drying operation vaporizes the moisture (generally referred to as moisture or other volatile liquid components) in the material by heating to escape so as to obtain a solid material having a prescribed moisture content. The purpose of drying is for material use or further processing requirements. For example, the wood can be dried before making wood mould and woodware to prevent the product from deforming, and the ceramic blank can be dried before calcining to prevent the cracking of the finished product. In addition, the dried material is also convenient to transport and store, such as drying the harvested grain below a certain moisture content to prevent mildew. Since natural drying is far from meeting the requirements of production development, various mechanized dryers are increasingly widely used.
