[0002] Drying equipment, also known as dryers and driers, is a device used for drying operations. It vaporizes the moisture in the material (generally water or other volatile liquid components) by heating to obtain solid materials with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing. For example, drying wood before making wooden molds and wooden products can prevent the products from deforming, and drying ceramic blanks before calcining can prevent the finished products from cracking. In addition, the dried materials are also convenient for transportation and storage, such as drying the harvested grain to below a certain moisture content to prevent mildew. Plywood is one of the commonly used materials for furniture. It is a man-made board made of wood segments peeled into veneers or wood blocks sliced ​​into veneers, and then glued with adhesives to form three-layer or multi-layer plate-like materials. In order to make plywood more environmentally friendly, the adhesives used usually do not add formaldehyde. After forming, plywood is usually dried using drying equipment.
