Abstract
Un mecanismo extrusor de gusano para el procesamiento de materiales de fuerte desgasificacion comprende un extrusor principal para el procesamiento adecuado del material, un dispositivo de alimentacion y de descarga de material y un dispositivo de desgasificacion sobre el extrusor principal para la descarga de la corriente de gas que proviene de la porcion de evaporacion; para que la corriente de gas se ramifique en por los menos tres corrientes separadas, el dispositivo de desgasificacion comprende un primer puerto de desgasificacion y por lo menos dos elementos de desgasificacion que están opuestos radialmente uno del otro en relacion al extrusor principal, y que están dispuestos entre la porcion de evaporacion y el primer puerto de desgasificacion, y los cuales están diseñados preferiblemente como extrusores de gusano auxiliares que se abren radialmente dentro del extrusor principal.
