Abstract

LA PRESENTE INVENCION SE REFIERE A UN PROCEDIMIENTO NUEVO Y PERFECCIONADO PARA LA COCCION CONTINUADA DE MATERIAL DE FIBRA, CARACTERIZADO PORQUE LAS TEMPERATURAS Y LOS NIVELES DE MATERIAL ALCALINO SE CONTROLAN A FIN DE MANTENERSE DENTRO DE NIVELES ESPECIFICOS EN DIFERENTES ZONAS DEL PROCESO DE DIGESTION, A FIN DE OPTIMIZAR EL CONSUMO DE PRODUCTOS QUIMICOS Y ECONOMIZAR CALOR Y CONSEGUIR, AL MISMO TIEMPO, PROPIEDADES EXCELENTES PARA LA PASTA. EL MATERIAL DE FIBRA SE CALIENTE E IMPREGNA CON AYUDA DE LEJIA NEGRA HASTA UNA TEMPERATURA INFERIOR A 140°C, Y SE HACE PASAR A CONTRACORRIENTE A UNA ZONA DE IMPREGNACION (A). EL MATERIAL DE FIBRA CALENTADO E IMPREGNADO SE TRANSFIERE A UNA ZONA DE COCCION A CONTRACORRIENTE (B) EN LA PARTE SUPERIOR DE UN DIGESTOR (6). AL MENOS UN 60% DE LA CANTIDAD DE LEJIA (F) QUE SE NECESITA PARA LA REACCION DE COCCION SE SUMINISTRA EN EL EXTREMO AGUAS ARRIBA DE LA ZONA DE COCCION A CONTRACORRIENTE (B), A FIN DE OBTENER UN NIVEL DE MATERIAL ALCALINO EFECTIVO SUPERIOR A 35G/L. LA TEMPERATURA DE COCCION DE LA ZONA DE COCCION A CONTRACORRIENTE (B) ES INFERIOR A 160°C. EL LEJIA APAGADA (E), CON UNA CANTIDAD DE MATERIAL ALCALINO EFECTIVO DE AL MENOS 13 G/L, SE RETIRA DE UN ANILLO DE FILTRO (8). UNA PARTE SUSTANCIAL DEL MORDIENTE APAGADO SE SUMINISTRA A LA ZONA DE IMPREGNACION.
