Airswept Turbo Dryers
The AirSwept Turbo Dryers are a new concept in drying technology. It will process anything from low solids slurries to low moisture powders. The flow of material through the dryer is controlled so that the product may be a fine, dry powder or a moist granular material.
Working principle
Three separate zones in the dryer control the rate of drying with the central retention zone determining the residual moisture content and physical size of the product. High temperature differentials are used but as with most Flash Dryers, the product temperature is lower than the wet-bulb temperature of the system. The heat source for the dryer is an oil or gas fired hot air generator, usually integrated with the drying cylinder. Product collection can be directly from the final zone of the drying tube, from a cyclone or from a bag filter. The dryer can have evaporation rates as high as eight tonnes per hour.
