Abstract

A centrifugal dryer (10) for removing surface moisture from pellets of resin material having a diameter generally ranging between approximately 0.015 to approximately 0.25 inches received from an underwater pelletizer. In one embodiment of the present invention, the dryer is constructed with smaller dimensions enabling it to effectively operate at low volume rates and be easily assembled and disassembled to facilitate cleaning and replacement or interchange of components with its overall size enabling it to be effectively used in small applications. In other embodiments of the present invention, the dryer is constructed with larger dimensions enabling it to effectively operate at high volume rates for use in commercial applications.
