Abstract

A method and apparatus for enhancing the evaporation and moisture removal from moisture laden products in a dryer. The invention combines the inventor's prior U.S. Pat. No. 4,719,761, with a rotating drying drum having filters at the output area and a separate pump for allowing condensation from a chilled coil to drain off, while a desiccant formed from pads or a rotatable wheel is part of a continuous feedback loop for recycling moisture. A condenser is positioned between the desiccant and the drying drum and is used as a heat exchange for both the air inlet to the drum and the air outlet from the drum. Additionally, the evaporator drain pipe can form an additional heat exchanger when the pipe is used in the pathway of air passing from the desiccant to the evaporator coil. The invention is useful for drying various items such as clothes, agricultural products, wood, vegetables, fruit and electric components such as wafers.
