Abstract: A centrifugal pellet dryer screen especially adapted for drying micropellets includes an exterior or outer support screen in the form of a cylindrical perforated plate, an inner screen of small wire mesh material, and an optional middle screen of wire mesh material sandwiched between the outer support screen and the inner screen. The screen layers are preferably diffusion bonded to each other. These multi-layer screens produce drier micropellets exiting the dryer and reduce banding of the micropellets and plugging of the dryer screen outlet holes.

Abstract: A method and apparatus for underwater pelletizing and subsequent drying of polyethylene terephthalate (PET) polymers and other high temperature crystallizing polymeric materials to crystallize the polymer pellets without subsequent heating. High velocity air or other inert gas is injected into the water and pellet slurry line to the dryer near the pelletizer exit. Air is injected into the slurry line at a velocity of from about 100 to about 175 m3/hour, or more. Such high-speed air movement forms a vapor mist with the water and significantly increases the speed of the pellets into and out of the dryer such that the PET polymer pellets leave the dryer at a temperature sufficient to self-initiate crystallization within the pellets. A valve mechanism in the slurry line after the gas injection further regulates the pellet residence time and a vibrating conveyor after the dryer helps the pellets to achieve the desired level of crystallinity and to avoid agglomeration.
