Drying equipment, also known as dryers or dryers, is used for drying operations. It uses heat to vaporize and remove moisture (generally water or other volatile liquid components) from materials, resulting in 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 molds or woodenware prevents deformation, and drying ceramic blanks before firing prevents cracking. Additionally, dried materials are easier to transport and store; for instance, drying harvested grain to a certain moisture content prevents mold growth. Because natural drying is far from meeting the needs of production development, various mechanized dryers are increasingly widely used.
