| 20120024125 | LOOP CUTTER KNIFE FIXTURE WITH REPLACEABLE BLADES - A loop cutter knife fixture for cutting vegetable products such as raw potatoes into spiral or helical loops. The knife fixture includes a circular blade holder adapted to be rotatably driven within a vegetable product flow path. The blade holder includes a central core cutter in combination with a spiral base plate defining a radial slot between axially spaced upstream and downstream ends thereof. Small slits are formed in this base plate for seated reception of preferably multiple U-shaped strip blades, which are in turn overlaid and clamped in place beneath a generally pie-shaped slab blade having a sharpened knife edge exposed at the base plate radial slot and held in place by preferably multiple clamp screws. The strip blades and/or the slab blade are formed from an inexpensive material, such as sheet metal or the like, whereby blade changeover is quick and economical. | 02-02-2012 |
| 20120167737 | LATTICE CUTTING MACHINE - A lattice cutting or slicing machine includes a multi-knife lattice cutting plate mounted in-line along an hydraulic flow path through which vegetable products such as potatoes are propelled in single file by a hydraulic fluid such as water. The lattice cutting plate is orbitally driven for engaging in succession each of the multiple knives thereon with the vegetable product to form lattice cut slices wherein successive generally corrugated cuts are angularly oriented typically perpendicular to each other, and further wherein the depths or troughs of the corrugated cuts on opposite sides of each slice intersect in the preferred form to define a pattern of corrugations interrupted by small openings. | 07-05-2012 |
| 20130087032 | ROTARY KNIFE FIXTURE FOR CUTTING SPIRAL, TEXTURED POTATO PIECES - A rotary knife fixture for cutting vegetable products such as raw potatoes into spiral shapes. The knife fixture includes a ring-shaped blade holder driven rotatably within a hydraulic product flow path. The blade holder includes at least one cutting blade, wherein the blade is twisted from a generally longitudinally aligned center axis outwardly in opposite circumferential directions with a sharpened leading edge set at a desired pitch angle. By controlling the pitch angle of the blade in relation to the blade rotational speed and velocity at which the potato travels along the hydraulic flow path, the resultant spiral cut shape is selected. By using multiple cutting blades at known axially spaced positions and selecting the angular position of each cutting blade in succession, the number of spiral shapes cut from each potato is selected. The blades can have a nontextured straight-cut edge, or a textured crinkle-cut edge, or a combination. | 04-11-2013 |
| 20140260862 | CONSTANT ACCELERATION HYDROCUTTING SYSTEM - An improvement to hydrocutting systems includes a curved shape for the acceleration and deceleration sections of the system. In the acceleration and deceleration tubes, the curvature of the sidewall is non-linear along its length, and the water flowing therein accelerates, positively or negatively, at a substantially constant rate. In an embodiment, there is a second curvature, which may be offset from the first curvature by about 90 degrees, that accelerates the water at a second, different substantially constant rate, in order to align the food product both lengthwise and rotationally to a desired orientation. | 09-18-2014 |

| 20160121503 | Acceleration Tube and Cutter Head Housing Retainer for Hydraulic Cutting System - An apparatus for a hydraulic cutting system having a pump that propels solid food products suspended in a working liquid through a blade. An elongated case is mounted in, and is longitudinally-movable relative to, a frame. The case has at least one rigid member connected to an upstream ring and extending to a downstream ring. A substantially flexible, tapered tube is mounted within, and substantially coaxially to, the case. At least a first portion of the case is moveable from a closed position, in which the tapered tube is retained in the case, to an opened position, in which the tapered tube may be removed from the case, relative to a second portion of the case. | 05-05-2016 |
