Air flow, countercurrent to product flow, is introduced in the upper portion of the Gala centrifugal dryer. This countercurrent airflow prevents moisture from escaping with the product and further reduces the surface moisture level. In many cases, a surface moisture of 500 ppm or less (0.05%)* can be achieved. Centrifugal Dryers 1/13/05 6:57 PM ...
