ABSTRACT:
A material drying apparatus having a sealable chamber for receipt of wet material, such as clothing. Material placed into the chamber is dried upon the evacuation of air from the chamber wherein moisture drawn from the material is condensed on a condensate coil placed in the chamber. Heating coils placed around the chamber or beneath a drawer elevate the temperature to enhance condensate operation providing an energy efficient material dryer requiring no make-up air. Drum or thermal blanket enhances temperature elevation. Condensed water is purged after the drying process although provisions provide for an interim purge should excess liquid be drawn from the material.
