Abstract: A cutter blade for a food processor or chopper has a scimitar-shaped body with a convex cutting edge leading in the direction of rotation about an axis perpendicular to its major faces, one of these faces being stepped to form one or more ancillary edges inwardly of the cutting edge and in different planes of rotation. The several ancillary edges may be separated from one another by surface depressions and preferably lie at an acute angle to the direction of rotation.

Abstract: A die for use in a food chopper downstream of the coarse-cut die is formed with an array of like small-diameter holes and on each of its faces with an array of grooves having a width substantially greater than the diameter of the through-going holes and extending at an angle to the blade which sweeps over the upstream face of this die. Particles which have passed through the upstream die and which are unable to pass through the small-diameter holes in the downstream die are caught in the grooves and cut between the downstream edge of the grooves and the cutter blade. These grooves are arrayed such that the cutter blade conducts the food along the grooves, and the grooves may be of decreasing depth in the direction of travel of the material therealong so as to allow the material to be reduced to very small size. At the inner ends the grooves may terminate in large-diameter throughgoing holes which are connected to an arrangement for carrying unchoppable particles out of the chopper.
