METHOD AND APPARATUS FOR DRYING GRANULAR SOLIDS WITH VENTURI POWERED GAS CIRCULATION

摘要

A method and an apparatus for drying plastic pellets, utilizes a venturi air mover (20) in a recirculation loop communicating with a drying hopper (10) containing the plastic pellets. A portion of moist air flow in said recirculation loop is vented to the ambient atmosphere upstream of the venturi air mover. A conventional source of compressed air (16) is dried and supplied to the venturi air mover to provide the exclusive motive power for moving air through the recirculation loop.
