Zerkleinerungsvorrichtung für schneidbare Stoffe zur Erzeugung prismatischer, insbesondere kubischer Partikel

摘要

The materials, especially of animal or vegetal origin are cut into prismatic, preferably cubic particles by means of a three-dimensional cutting sequence. The apparatus used consists of two concentric knife rotors, wherein the inner knife rotor 6 is multiply equipped with cutting tools 15, 16 effecting the cutting of the slices and stripes. Thereby the gate-like cutting tools 16 cutting the stripes are arranged in the inlet zone of the passage channels 14 in front of the plate-shaped cutting tools 15 peeling off the slices. The outer knife rotor 5 is equipped with several plate-shaped knives 20 which are cross-cutting the material stripes coming out of the passage channels 14 according to the required particle length. A guiding system pressing the pieces of material in cutting position against the cutting tools 15, 16 is arranged in the interior of the inner knife rotor 6. It may consist either of a spiral-shaped guideway fastened onto the housing door or of rotating guiding vanes. <IMAGE>
