Abstract

SE PRESENTA UN METODO PARA PRODUCIR PULPA DE FIBRA A PARTIR DE UN MATERIAL FIBROSO QUE CONTENGA LIGNOCELULOSA, EN DONDE LA MATERIAL DE FIBRA SE SUMINISTRA PRIMERO AL INTERIOR DE UN PRECALENTADOR (10) Y SE PRECALIENTA Y EL MATERIAL PRECALENTADO SE DESCARGA POSTERIORMENTE EN UNA REFINADORA (18) EN DONDE LA PULPA DE FIBRA SE PRODUCE MEDIANTE LA DESFIBRILACION DEL MATERIAL DE FIBRA. EL MATERIAL DE FIBRA SE MANTIENE EN EL PRECALENTADOR (10) DURANTE UN TIEMPO DE RESIDENCIA PREDETERMINADO, QUE NO DEPENDE DE LA PRODUCCION DE PULPA DE FIBRA, MIDIENDO LA PRODUCCION DE PULPA DE FIBRA Y USANDOLO PARA CONTROLAR EL NIVEL DE MATERIAL DE FIBRA EN EL PRECALENTADOR (10).
