Drying oven is a device that uses heat and often forced air circulation to remove moisture from materials, accelerating drying and hardening processes. These ovens are essential in various fields, from laboratories and pharmaceutical manufacturing to food processing and industrial coating, ensuring materials are dry, sterilized, or cured to specifications. Key features can include temperature control, specific air circulation methods (like mechanical or gravity convection), and safety features for handling explosive vapors or meeting regulatory standards.
