Equipment used for drying operations, which vaporizes moisture (generally refers to water or other volatile liquid components) in materials 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 easy to transport and store, such as drying the harvested grain to below a certain moisture content to prevent mildew.
