<p>A dryer, for drying various materials, having an enclosed housing including an inlet port and an outlet port. Contained within the housing, in between and on opposite sides of the ports, are first and second desiccant columns each containing a desiccant material. An inlet plenum is located between the inlet port and the desiccant columns, and an outlet plenum is located between the restricted outlet port and the desiccant columns, with the inlet and outlet plenums communicating through the desiccant columns. A valve damper is pivotally supported within the housing, located between the desiccant columns, having one end extending across the inlet port to alternately direct air blown into the housing by a blower into one of the desiccant columns. A poppet valve assembly is actuated by the damper to direct dry air into the opposite desiccant column, regenerating that column, before exhausting the air out of the housing. An intermittently operable time controlled solenoid pivots the damper before the desiccant approaches saturation and before the desiccant loses its heat of adsorption.</p> |
