Wyssmont N-28 Spiral Turbo-Dryer

The Turbo-Dryer 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 levelled. After one revolution, it is wiped to the next tray where the operation is repeated. Trays are contained in an enclosure which heated air or gas is circulated by internal fans.
