Abstract

Un método y un sistema para procesar polímeros que incluyen proporcionar un polímero fundido y procesar el polímero transformándolo en componentes maleables para enviarlo a una superficie transportadora enroscada en forma de espiral. Se pueden utilizar fuerzas vibratorias para impulsar los componentes a lo largo de la longitud de la superficie transportadora, a medida que experimentan la cristalizacion o el secado o la cristalizacion y el secado. Se puede emplear el control de temperatura suplementario adicional para producir la cristalizacion y/o el secado de los componentes a lo largo de la superficie transportadora.
