Since centrifugal dryers operate on three basic principles—residual heat in the pellet, centrifugal action, and countercurrent ambient air flow—proper operating parameters must be established For example, if the process-water temperature is too low, the resulting pellet temperature will be too low to flash off sufficient surface moisture.
