Abstract
DISPOSITIVO DIGESTOR TUBULAR DE ETAPAS MULTIPLES PARA PRODUCIR PULPA DE ALTA CALIDAD. COMPRENDE UN TRANSPORTADOR (10) QUE INTRODUCE LA FUENTE DE FIBRA EN EL TRANSPORTADOR DE TORNILLO (11), DOSIFICANDO ESTE LA FIBRA E INTRODUCIENDOLA A TRAVES DE LA CONDUCCION (12) EN UN ALIMENTADOR DE TORNILLO (13), DONDE SE MEZCLA CON VAPOR DE AGUA Y ENTRA EN LA CAMARA TUBULAR (17) POR LA CONDUCCION (15) Y LA (14), SALIENDO DE ESTA CAMARA POR LA CONDUCCION (18) Y PASANDO A LA PURGA EN (19), DONDE DESPUES DEL PURGADO, LA FIBRA PASA POR LA CONDUCCION (20) Y ENTRA EN LA CAMARA TUBULAR (21). ESTO PROPORCIONA UN PROCEDIMIENTO CONTINUO EN EL QUE LA FIBRA TIENE UN TIEMPO DE PERMANENCIA MAS LARGO EN LA CAMARA TUBULAR (21) QUE EN LA (17), SALIENDO LA FIBRA POR LA CONDUCCION (21) Y SIGUIENDO PARA SU POSTERIOR TRATAMIENTO.
