A centrifugal pellet dryer (10) including a stationary cylindrical screen (58), a driven elevating rotor (54) in said screen elevating wet pellets inside the screen and imparting radial forces to the wet pellets to impact them against the interior of the screen to enable moisture on the pellets to be separated and discharged through the screen, a housing (15) enclosing the screen (58) and rotor (54) and including an inlet (70) for a slurry of pellets, an outlet (76) for dried pellets and an outlet (74) for water removed from the pellets. The side walls of the housing are constructed of a plurality of relatively large, flat panels (12,14,16,18) made of plastic sheet material which are supported in a metal framework (11) to attenuate noise of the dryer (10) produced by rotation of the drier rotor (54) and impact of the wet pellets against the screen (58). A dewaterer in advance of the dryer (10) also has walls made of plastic sheet material. |
