Abstract

UN PROCESO Y UN DISPOSITIVO PARA LA PRODUCCION DE MATERIALES FIBROSOS DE ALMIDON MEDIANTE LA EXTRUSION DE UNA DISPERSION O SOLUCION ACUOSA DE UN MATERIAL DE ALMIDON EN UN FLUJO DE COAGULANTE SALINO, SEGUN EL CUAL LA DISPERSION O LA SOLUCION ACUOSA SE EXTRUYEN A TRAVES DE UNA PARED TUBULAR MICROPOROSA EN UN CAMARA COLOCADA ALREDEDOR DE DICHA PARED MICROPOROSA DE TAL MODO QUE SE OBTENGA UN FLUJO DE EXTRUSION DEL MATERIAL DE ALMIDON QUE RODEE A DICHAS PAREDES TUBULARES Y LA COAGULACION DE LA EXTRUSION SE LLEVE A CABO A BASE DE ALIMENTAR EL FLUJO DEL AGENTE DE COAGULACION EN LA CAMARA ANULAR PARALELA A LA SUPERFICIE DE EXTRUSION. LAS FIBRAS OBTENIDAS SE PUEDEN UTILIZAR EN PARTICULAR EN LA INDUSTRIA DEL PAPEL EN SUSTITUCION A LAS FIBRAS DE CELULOSA O JUNTO CON ELLAS.A PROCESS AND DEVICE FOR THE PRODUCTION OF FIBROUS STARCH MATERIALS THROUGH THE EXTRUSION OF A DISPERSION OR AQUEOUS SOLUTION OF A STARCH MATERIAL IN A FLOW OF SALT COAGULANT, ACCORDING TO WHICH THE DISPERSION OR AQUEOUS SOLUTION IS EXTRUED BY TUBULAR MICROPOROUS IN A CHAMBER POSTED AROUND SUCH A MICROPOROUS WALL SO THAT A FLOW OF EXTRUSION OF THE STARCH MATERIAL IS OBTAINED WHICH SURROUNDS SUCH TUBULAR WALLS AND THE COAGULATION OF THE EXTRUSION FROM THE CAIM OF THE FLOOR OF THE BASE OF THE FLOOR FROM THE BASE OF THE FLOOR TO THE BASE OF THE FLOOR FROM THE BASE OF THE FLOOR FROM THE BASE OF THE FLOOR TO THE BASE OF THE BASE OF THE FLOOR FROM THE BASE OF THE BASE COAGULATION IN THE NULL CHAMBER PARALLEL TO THE EXTRUSION SURFACE. THE FIBERS OBTAINED MAY BE USED IN PARTICULAR IN THE PAPER INDUSTRY IN REPLACEMENT WITH OR IN CONJUNCTION WITH CELLULOSE FIBERS.
