Abstract

EL PRESENTE INVENTO SE REFIERE A UN DIGESTOR PARA LA COCCION CONTINUA BAJO ELEVADAS Y PRESION DE UN MATERIAL DE FIBRA EN UN DIGESTOR VERTICAL (1), DONDE LA ENTRADA DE MATERIAL DE FIBRA Y DE 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 UN FILTRO (1D) DEL DIGESTOR QUE SE ENCUENTRA ENTRELA PARTE SUPERIOR E INFERIOR DEL DIGESTOR, Y EL MATERIAL DE FIBRA SE EXPULSA DESDE LA PARTE INFERIOR (1C) DEL DIGESTOR, Y AL MENOS UN FILTRO (2) EN LA MITAD INFERIOR DEL DIGESTOR, DONDE AL MENOS UNO DE DICHOS FILTROS (1,2) TIENE POR LO MENOS UN ELEMENTO DE FILTRO (2A) DEL CUAL LA PRINCIPAL CONFIGURACION ES DE FORMA ANGULAR, PREFERIBLEMENTE RECTANGULAR, MAS PREFERIBLEMENTE CUADRADA CON UNA CARA DE FILTRO (3A) CUYA AREA TOTAL ES MAYOR A 1 M2, Y LA CUAL ESTA ADOSADA A LA PARED DEL DIGESTOR (1A), DE MANERA QUE FORMA UN VOLUMEN SELLADO (V) DESDE EL CUAL EL LIQUIDO SOLO PUEDE SER SUMINISTRADO Y RETIRADO A TRAVES DE DICHA CARA DE FILTRO (3A), Y UNOS MECANISMOS DE ENTRADA Y SALIDA (15) RESPECTIVAMENTE, PENETRANDO LOS MECANISMOS DE SALIDA LA PARED DEL DIGESTOR (1A).
