Abstract

Un sistema de procesamiento de caucho de guayule (100) y un método (200) consiste en mezclar un caucho de guayule y al menos una mezcla solvente en un extrusor (102), con el fin de eliminar la resina que se encuentra en la micela de guayule (104) y precipitar la micela de guayule (104) para formar un precipitado. La al menos una mezcla de solventes (138, 140, 142) tiene un primer solvente configurado para precipitar el caucho de guayule, y un segundo solvente configurado para hinchar el precipitado resultante. En particular, puede usarse una serie de mezclas de solventes (138, 140, 142) en diferentes localizaciones a lo largo del extrusor (102) y además puede incluir distintas mezclas del primer solvente y el segundo solvente, introducidas en las diferentes localizaciones, y tener diferentes relaciones del primer solvente y el segundo solvente.
