<p>Solidly frozen meat blocks or the like are subjected to the action of a constantly rotating, convolute blade having outer edges along its convolutions that include discrete, helical cutting stretches and lengths for severing the blocks by successive slices into generally rectangular slabs of substantially uniform thickness suitable for further subdivision into elongated strips and thence into cubes usable, for example, in stews. By virtue of the helical nature of the blade, the machine is self-feeding, and provision is made for a dwell time during which uniform block advancement continues but slicing is interrupted. This is accomplished by use of an intermediate stretch on the blade edge which is concentric to its axis of rotation such that the block is always under the control of the blade because each succeeding slice is therefore commenced and sufficiently deepened prior to completion of the preceding slice. Each slicing action starts rapidly and the rate of slicing is progressively decreased. Moreover, the cut may start at one corner of the block and be gradually widened across the top and along one side of the block before reaching a full length cut diagonally across the block, the forces also being diagonal toward a lower, well-supported corner of the tilted block. A primary function of a trailing convolution of the blade is also block control in addition to its control of the partially cut-away slabs.</p> |
