Abstract:
1. A method of multiple sequential processing to achieve crystallization of polymeric material comprising: feeding the polymeric material to a mixer, mixing the polymeric material in the mixer, extruding the polymeric material from the mixer, pelletizing the extruded polymeric material, first transporting the pelletized polymeric material to a first dryer, a first transport medium used to transport the pelletized polymeric material at a first temperature, first drying the pelletized polymeric material in the first dryer, second transporting the dried pelletized polymeric material to a pellet crystallization system, a second transport medium used to transport the pelletized polymeric material at a second temperature, crystallizing the pelletized polymeric material in the pellet crystallization system, third transporting the crystallized and pelletized polymeric material to a second dryer, a third transport medium used to transport the crystallized and pelletized polymeric material at a third temperature, and second drying the crystallized and pelletized polymeric material, wherein the first, second, and third temperatures are different.
