Abstract
A centrifugal pellet dryer with a self-cleaning rotor seal, replaceable wear plates, and a fluid powered dewatering tower is presented. The self-cleaning rotor seal includes a plurality of grooves that are structured to eject pellet debris that migrates into between the seal and the housing for the rotor. The replaceable wear plates are secured to the rotor at locations such that they contact pellets that are entering the rotor housing. The dewatering tower includes a helical augur that dewaters a pellet slurry and delivers partially dried pellets to the rotor housing.
