Abstract
A self-cleaning centrifugal pellet dryer and method for removing surface moisture from pellets and enabling complete removal of all pellets from the dryer after each drying cycle. By eliminating dried pellets retained in the dryer, contamination of different type pellets dried during a subsequent drying cycle is avoided. Air and water under pressure are discharged toward various pellet hang-up points in the dryer to remove retained pellets.
