ABSTRACT:
A cabinet dehydrator for home preservation of food under relative humidity, pressure, and temperature restraints. Intake air is obtained from the surrounding atmosphere and displaced into the dehydrator over heating elements by a blower. This heated air is ported through a manifold defined by the cabinet walls having a sloping chamber which narrows toward the top of the cabinet to evenly displace the heated air over the tops of removable drying trays. The heated air withdraws moisture from the articles of food placed on the drying trays, and is partially exhausted through exhaust portals, depending upon the relative humidity, temperature, and pressure of the surrounding atmosphere. The remaining heated air is mixed with an amount of surrounding air entering through intake portals to replace the amount exhausted. This mixture of heated air and intake air is then heated and recirculated by the blower until the articles of food are dried.
