Abstract

EL PRESENTE INVENTO SE REFIERE A UN DIGESTOR PARA LA COCCION CONTINUA BAJO TEMPERATURAS Y PRESION ELEVEDAS DE MATERIAL DE FIBRA EN UN DIGESTOR VERTICAL (1) DONDE LA ENTRADA DEL MATERIAL DE FIBRA Y DEL LIQUIDO DE COCCION TIENE LUGAR EN LA PARTE SUPERIOR DEL DIGESTOR. LA RETIRADA DEL LICOR DE COCCION RESIDUAL SE LLEVA A CABO DESDE AL MENOS UNA REJILLA EXPRIMIDORA DEL DIGESTOR (1D) ENTRE LA PARTE SUPERIOR E INFERIOR DEL DIGESTOR, Y EL MATERIAL DE FIBRA ES ALIMENTADO DESDE LA PARTE INFERIOR (1C) DEL DIGESTOR, DONDE UN DIGESTOR EXISTENTE (1) POSEE UNA REJILLA EXPRIMIDORA ADICIONAL (2), COLOCADA POR ENCIMA DE LA REJILLA EXPRIMIDORA MAS BAJA (1B) DEL DIGESTOR, DE MANERA QUE LA TEMPERATURA EN TODAS LAS ZONAS DE COCCION INVOLUCRADAS EN EL DIGESTOR PUEDEN MANTENERSE ESENCIALMENTE AL MISMO NIVEL DE TEMPERATURA.
