Abstract

A cutter blade assembly 100 for producing elongated string cuts of food product using a hydraulic cutting apparatus where the elongated string cuts produced are free from feather cuts and compression cell damage, and further have small cross-sectional areas. The cutter blade assembly 100 is constructed from a front inlet adapter plate 101 having an inner longitudinal passageway therethrough shaped to form a conical converger 102. Pyramidal knife supports 103, 104, 105 and 106, are attached in opposing pairs around conical converger 102 to the back of front inlet adapter plate 101 to form a pyramidal frame. A plurality of strip knives are attached in a staggered perpendicular interlocking arrangement to form a sequential cutting grid.

Claims

1. A cutter blade assembly for use in a hydraulic food cutting apparatus which comprises:

a frame defining a longitudinal passageway having upstream and downstream ends for passage of food product and carrier medium therethrough;

a first plurality of strip knives being removably attached to said frame in pairs, in parallel spaced relation, along the longitudinal passageway;

a second plurality of strip knives each having engagement slots therein for perpendicularly engaging the strip knives of said first plurality of strip knives, said second plurality of strip knives being attached to said frame in pairs alternately interspaced between the pairs of said first plurality of strip knives and having their engagement slots in engagement with the next downstream pair of the first plurality of strip knives, and in perpendicular spaced relationship with the adjacent upstream pair of the first plurality of strip knives;

said first and second pluralities of strip knives being attached to said frame to define a pyramidal array having a converging point at the downstream end of said frame; and

a pair of quartering knives disposed perpendicularly one to the other and removably attached to said frame at the converging point of said pyramidal array and being further disposed to engage and quarter each of the food products passed therethrough.

2. The cutter blade assembly of claim 1 further comprising a front inlet adapter plate having an inner longitudinal passageway shaped to form a conical converger for the acceleration of food product therethrough being attached to the inlet of the frame.

3. The cutter blade assembly of claim 2 wherein the strip knives have a flat side and a beveled side which form a cutting edge, disposed within said passageway and oriented so said flat sides face the longitudinal passageway centerline.
