Abstract
A centrifugal pellet dryer in which centrifugal action is used to separate water from polymer pellets incorporating unique structural and functional features including but not limited to utilizing the pellet outlet nozzle as an air inlet, feeding the pellet/water slurry upwardly from underneath the dryer directly into the lower end of the rotor of the dryer, providing a sloped bottom in the dryer to facilitate ease of cleaning, providing a hinged cylindrical screen encasing the rotor to enable the screen to be removed for easier cleaning, closing the top of the dryer and using the pellet outlet for the air inlet which will eliminate flat spots in the pellet outlet to make it easier to clean and eliminate cross contamination which occurred in previous dryers as pellets frequently ricocheted or bounced into the air inlet filter housing and later fell back into the dryer, providing large panel doors to facilitate cleaning and constructing the dryer housing with flat sides which provide more versatility in the location of connections and enabling the dryer housing to be of double wall construction for receiving insulation to reduce noise.
