DRYING APPARATUS AND METHODS

摘要

A method and apparatus is disclosed for drying objects or materials using microwave energy. The microwave energy raises the temperature of the objects or materials (1) in a drying chamber (16) causing moisture to be released from the objects or materials. The drying chamber is supplied with a steam of dehumidified air which picks up the moisture from the surface of the objects or materials. This air stream is then passed to a dehumidifying unit (8, 9, 10, 11) which removes the moisture from the air stream which is then recirculated back through the drying chamber. The air may be reheated (12) before being reintroduced into to the drying chamber.
