Abstract

The extrusion outlet is partic. intended for the prodn. of strips of a pasty prod. by the cooking-extrusion-expansion process; a diffusing grid is placed between the head of the extruder screw and the pressure equalisation chamber at the outlet. The outlet has a diffusing grid which is located between the point of one of the screws of the extruder and the pressure-equalising chamber. The grid has two series of channels, parallel with each other and lying within the arcs of a circle which are symmetrical w.r.t. the extrusion nozzle; the grid has a central channel to avoid the formation of a stagnant zone in the equalisation chamber with the possibility of a blockage through an accumulation of the pasty prod. The portion of the appts. from the mixer to the outlet is heated by an induced electric current. The pasty material is forced by the screw into the pressure zone, between the end of the screw and the female part of the grid; the rotary movement is broken and transformed into a linear movement. The flat extruded strip passes under tension rods and is taken by a conveyor through a drying tunnel; it then passes between rollers to a rotary cutter which produces pieces of the required dimensions. These pass through a roasting tunnel and are finally cooled by a current of air and packed. The nozzles produce a sheet of paste which is uniform in thickness over the whole of its width; the streams of paste coming through the channels diffuse together to give a homogeneous sheet so that a regular prod. can be obtd.
