fluidized bed dryer flash dryer specific gravity separator FLUIDIZED BED DRYER Fluidized Bed Dryer - The application of the Oliver patented fan system to produce uniform, precise air flow has created a simple inexpensive fluidized bed dryer. The flash drying system provides a solution to many challenging thermal processing problems. The fluidized bed dryer offers instantaneous moisture removal from material with diverse size and consistency characteristics and there is a long retention time on the drying table. A large vibrating table also minimizes material degradation and dust control, heat and chilling air systems are readily available.
