| 干燥的目的是为了物料使用或进一步加工的需要。如木材在制作木模、木器前的干燥可以防止制品变形，陶瓷坯料在煅烧前的干燥可以防止成品龟裂。另外干燥后的物料也便于运输和贮存，如将收获的粮食干燥到一定湿含量以下，以防霉变。由于自然干燥远不能满足生产发展的需要，各种机械化空气干燥机越来越广泛地得到应用。 The purpose of drying is to meet the needs of material use or further processing. For example, the drying of wood before making wood molds and woodwork can prevent the deformation of products, and the drying of ceramic billets before calcination can prevent the cracking of finished products. In addition, the dried materials are also convenient for transportation and storage, such as drying the harvested grain to a certain moisture content, in order to prevent mildew. Because natural drying is far from meeting the needs of production development, a variety of mechanized air dryers are more and more widely used. |
