Dough is extruded from a screw extruder through a nozzle, preferably a twin-slot nozzle, and an apertured blocking plate is placed between the tip of the extrusion screw and the nozzle assembly for making the pressure distribution across the dough in a pressure equilization chamber between the blocking plate and the nozzle more uniform and for controlling the rate of flow of the dough towards the extrusion nozzle slots. The blocking plate has two series of parallel channels arranged on two opposed arcs of the same circle centered on the central axis of t...
In an extruder wherein a dough mixture is supplied under pressure from an extrusion screw rotating about its central longitudinal axis through an extrusion head to a nozzle, said screw having a conically shaped tip, the improvement comprising: a diffuser grid mounted within said extrusion head and between said tip and the nozzle, wherein there is provided a pressure equalizing chamber between said grid and said nozzle, said grid having a substantially planar surface facing said nozzle and an inwardly conical surface facing said tip, the conical surface o...
