Dryer operates at temperatures to 650 degrees C

February 18, 2008
A recent increase in capacity required an additional L-size TURBO-DRYER® to heat-treat a fine (70 micron) metal oxide powder. This design is capable of operating at temperatures up to 650°C to calcine or sinter metal powders. The unit includes an internal electrical heating system to provide the heat to remove the residual moisture. A small purge of dry air or nitrogen is used to purge water vapor from the system, keeping fines carryover to a minimum. The TURBO-DRYER® is a proprietary continuous tray dryer design that consists of a stack of rotating circular trays in a sealed enclosure. Material is fed onto the top tray, and after each revolution is wiped onto the next lower tray. The internal TURBO-Fans circulate heated gas in the enclosure to provide the drying medium.
