Drying ovens are a type of industrial equipment used to dry materials such as wood, paper, and food. The two most common types of drying ovens are oasts and KILNS. Oasts are heated chambers with a fan that circulates hot air to evenly dry the material. KILNS are heated chambers with a controlled atmosphere, such as humidity or temperature, to dry the material. Both oasts and KILNS are used in a variety of industries, including food processing, woodworking, and paper production.
