Turbo-Dryer delivers uniformly dried product because material is intermittently redistributed with plug-flow operation. The environmentally sealed unit consists of a stack of slowly rotating circular trays. Material is fed onto the top tray. After one revolution, the material is wiped onto the next lower tray, where it is mixed and leveled. After another revolution, the material is wiped to the next tray, where the operation is repeated. The dryer can handle temperatures up to 1200¡F and can adjust to varying feed rates.
