Abstract
A process and device produce fibrous starch materials through extrusion of a dispersion or aqueous solution of starch material in a flow of saline coagulant. The dispersion or aqueous solution is extruded through a microporous tubular wall in an annular chamber surrounding the microporous wall to obtain an extrusion flux of starch material which surrounds the tubular wall. Coagulation of the starch material is carried out by feeding a flow of coagulation agent in the annular chamber parallel to the extrusion surface. The fibers obtained from the process or device are able to be used in the paper sector as a substitution for or in combination with cellulose fibers.
