Abstract
A method and apparatus for disintegrating soft food materials. A disintegrating element having screw threads and cutting edges on the periphery of the threads is rotated about its axis and reciprocated in directions substantially parallel to a surface of a mass of the material to be comminuted. The cutting edges engage and comminute the material at such surface.
Claims6
A machine for disintegrating a soft food material comprising:
- (a) a disintegrating element having a pair of oppositely directed screw threads disposed about an axis, each of said threads occupying a portion of the length of said disintegrating element;
- (b) means for rotating said disintegrating element about said axis in a predetermined direction, each of said threads having at its periphery a substantially continuous cutting edge directed in the axial direction in which such thread appears to move upon rotation in such predetermined direction;
- (c) means for reciprocating said disintegrating element transversely of said axis, so that the disintegrating element moves in a predetermined plane of reciprocation;
- and
- (d) means for positioning a mass of said soft food material so that a surface of said mass is disposed parallel to said plane of reciprocation and such surface is engaged by said cutting edges.
