ABSTRACT:
A drying apparatus which utilizes air circulation to uniformly dry articles is disclosed. The apparatus includes an enclosure having racks upon which the articles to be dried are placed. An air exchanger couples to the enclosure to recirculate and heat air within the enclosure. Recirculation operates continuously while articles are being dried, and recirculation air temperature is maintained around a predetermined level through a thermostat coupled to heating elements. The air exchanger is configured so that air expelled from the air exchanger travels upward near the enclosure's walls, then downward in the center of the enclosure back to the air exchanger. An exhaust fan is controlled by a humidistat to remove humid air from the enclosure whenever the humidity within the enclosure exceeds a predetermined level. Consequently, a mean humidity level is maintained within the enclosure to prevent excessive drying, and substantial recirculation of air results in improved efficiency.
