Process and apparatus for the extrusion of a mixture of small plant parts with binders

摘要

The invention relates to a process and apparatus for the extrusion of a mixture of small plant parts with binders, in which the mixture is compressed by the extrusion die (11) of an extruder into a filling space (2). Due to the wedge-shaped widening of the filling space (2) into an angle (6), on reaching the final compression, there are obtained a density and a specific weight which are of the same or approximately the same magnitude at each and every point along a line in the direction of extrusion in the part of the strand formed by the compression stroke. The length of the compression stroke may be at least ten times the smallest cross-section of the strand and the length of the compression stroke is limited only by the size of the strand cross-section. <IMAGE>
