Abstract
La presente invención se refiere a un metodo para preparar una pulpa para digerirse en un procedimiento continuo de un material celulósico que contiene fibras, caracterizado porque comprende las etapas secuenciales de a) preimpregnar dicho material de fibra mezclándolo con licor de cocción a manera de formar una suspensión de fibra que tiene una concentración de fibras de aproximadamente 5 a 15 por ciento en peso; b) impregnar y fluidizar dicha suspensión de fibra bajo una presión superior a la presión atmosferica mediante la alimentación de la suspensión de fibra a una bomba centrífuga 5) que comprende un fluidizador que ejerce fuerzas de corte sobre la suspensión de la fibra, a manera de separar y desintegrar por lo menos parcialmente, los haces de fibra entre sí, c) alimentar dicha suspensión de fibra a una prensa por medio de una bomba centrífuga, mientras se continúa la impregnación a presión del material de fibra con licor de cocción de la suspensión de fibra, d) espesar la suspensión de fibra deshidratándola en la prensa mientras se somete la suspensión de fibra a una impregnación final a una presión por arriba de la presión atmosferica, a manera de formar una pulpa substancialmente impregnada completamente, que tiene una concentración de fibra de aproximadamente 20 a 40, preferiblemente 20 a 30 por ciento en peso y e) alimentar la pulpa resultante a un digestor por medio de la presión creada principal o completamente por la bomba centrífuga.
