Abstract

Un método de cristalizacion de una pluralidad de pellets de polímeros cristalizables que incluye un paso en el cual los pellets se ponen en contacto con un fluido de ajuste de temperatura en un cristalizador. El fluido ajusta la temperatura de los pellets debido a que posee una temperatura suficiente para permitir por lo menos la cristalizacion parcial de la pluralidad de pellets poliméricos mientras mantiene la temperatura de pellet promedio de la pluralidad de pellets por debajo de la temperatura de fusion de los pellets. Además se provee un cristalizador que implementa los métodos de la presente. Reivindicacion 39: Un cristalizador para cristalizar pellets poliméricos, el cual comprende: una entrada para recibir una pluralidad de pellets poliméricos; un transportador para transportar la pluralidad de pellets desde un primer sitio hacia un segundo sitio, donde dicho transportador agita los pellets a medida que los pellets están siendo transportados; un aplicador de fluido para poner en contacto la pluralidad de pellets poliméricos con un fluido; y una salida para remover la pluralidad de pellets de polímeros.
