Definitions
- This invention relates to the cutting of food product with hydraulic food cutting devices.
- it relates to a tensive cutting assembly for cutting food product.
- a variety of "hydro-cutting" devices for cutting food products into slices and sticks are known in the art and typically comprise a stationary array of cutting knives with a means to propel the food product through the knife array.
- the food product may be conveyed through the knife array by suspending the food product in a fluid stream, such as water.
- the typical hydraulic food cutting apparatus in use today has a receiving tank filled with a hydraulic carrier fluid, usually water, into which food product is dumped.
- a food pump draws its suction from the receiving tank, and pumps carrier fluid and the suspended food product from the tank into an inlet tube which aligns the food product before impact with a cutter assembly.
- Cutter blade assemblies include typically a frame and a stationary knife array typically including a plurality of individual knife blades mounted in a parallel and converging sequence to each other. If the food product is to be cut into slices, only a single such array need be utilized. However, if the food product is to be cut into sticks, such as potatoes for french fries, two such arrays are utilized with the knives in one array extending generally perpendicular to the knives in the other array.
- Cole, et.al. U.S. Patent 5,343,623 Knife Assembly for Cutting a Food Product, discloses a knife blade having a cutting portion defining a cutting edge, and holes adapted to accommodate means for attaching the knife blade to a mounting member, the centers of the mounting holes lying in the plane of the cutting edge.
- the knife blade is mounted in the knife assembly so that a tension force is exerted on the knife blade also in the plane of the cutting edge.
- the cutting edges of knives in an array are located in a common plane.
- Cole, et.al. further discloses an apparatus for mounting a plurality of individual blades for and applying tension to the plurality of individual blades in the plane of the cutting edges.
- a tensive cutting assembly includes a tensionable cutting member removably and interchangeably mounted in a tensive cutting head.
- the tensive cutting assembly may also include a means for monitoring tension during set-up of the tensive cutting assembly and monitoring tension and sensing failure or breakage of the tensionable cutting member during operation.
- the tensionable cutting member includes a strip of material having a pair of sides and a first edge and a second edge.
- the tensionable cutting member is formed having at least two leg segments and at least one bend connecting the two leg segments.
- the tensionable cutting member is formed having a plurality of leg segments connected by a plurality of bends producing a continuous and generally serpentine configuration forming an array formed of a single and continuous member.
- either the first edge or the second edge of the tensionable cutting member may be employed as the cutting edge of the tensionable cutting member.
- the cutting edge of the tensionable cutting member may be unsharpened and the sides and edges may be rounded or otherwise treated or dressed in order to eliminate edge and surface irregularities.
- the tensionable cutting member may be formed of a strip of sheet metal having a thickness of 0.005 inches to 0.001 5 inches and a width of 0.375 inches to 0.625 inches.
- the tensionable cutting member is formed of a hardened 301 stainless steel having a thickness of 0.008 inches and a width of 0.50 inches.
- the material used to form the tensionable cutting member should exhibit adequate tensile strength to perform as a tensionable cutting member and adequate ductility to allow its continuous configuration.
- the material used to form the tensionable cutting member should also exhibit a yield strength less than the tensile strength.
- the tensionable cutting member may be formed of a strip of sheet metal having a tensile strength of 1 75,000 psi to 275,000 psi and a yield strength of 80,000 psi to 180,000 psi.
- the tensionable cutting member is formed from a hardened type 301 stainless steel having a tensile strength of approximately 185,000 psi and a yield strength of approximately 140,000 psi.
- compositions or properties similar to the hardened 301 series stainless steel, or a type 1 7-4 PH stainless steel, are known to those skilled in the art and may be employed in the present invention as a tensionable cutting member.
- the tensive cutting assembly also includes a tensive cutting head having a first face and a second face and an aperture formed through its cross section for passage of food product through the tensive cutting assembly.
- various component parts of the tensive cutting head are machined of type 1 7-4 PH stainless steel, although other materials and forming methods known to those skilled in the art may be employed to practice the present invention.
- the tensive cutting head also includes at least one return which provides a bearing face about which the tensionable cutting member is substantially equally tensioned across its entire width when attached to and tensioned on the tensive cutting head.
- the preferred embodiment of the invention includes a plurality of returns divided into first and second pairings, the first and second pairings divided into opposing sets of returns. The returns are arranged sequentially, with an equal distance typically being observed between each of the sequential returns. Opposing sets of returns are offset laterally from one another a distance substantially equal to the distance between two sequential tensionable cutting member leg segments. This configuration allows the tensionable cutting member to be fit over the opposing sets of returns in a manner that permits a substantially parallel arrangement of the tensionable cutting member leg segments. The distance between sequential returns determines the distance between leg segments and therefore the cross-sectional dimension of the cut food product. In the preferred embodiment of the invention, the distance between tensionable cutting member leg segments is equal.
- Each return may also be configured having a bearing face across which the tensionable cutting member is fit.
- each return is formed having a pair of parallel faces and a radiused bearing face.
- the bearing face may be configured having an arcuate, circular or elliptical cross-section.
- the bearing face may also include a low friction surface against which the tensionable cutting member is fit and tensioned.
- the low friction face may be formed simply by polishing the bearing face of the return, by coating or treating the return, or by use of rollers. Alternately, the low friction face may be formed from a high density polymer.
- the height of the bearing face should be substantially equal to or greater than the width of the tensionable cutting member so that, as the tensionable cutting member is tensioned, substantially equal tensile forces are established across the width of the tensionable cutting member.

- a second tensionable cutting member removably mountable and tensionable on the second face of the tensive cutting head, presents a second array rotated at 90° on a plane substantially parallel to the first array.
- This embodiment of the tensive cutting assembly when employed within a hydraulic cutting device, renders cut food product having stick configuration.
- the tensive cutting head may be configured having only a single or first array, which will render cut food product having a slabbed configuration.
- a second tensionable cutting member affixed to a second tensive cutting head presenting a second array may be arranged in series within the in-line cutter assembly housing rotated at 90° to the first array to render cut food product having stick configuration.
- the tensive cutting assembly also includes at least one clamping member operatively associated with the tensive cutting head for securing the ends of tensionable cutting member to the tensive cutting head.
- the clamping member may comprise a variety of mechanical means so long as the clamping member is capable of restraining the tensionable cutting member end when the tensionable cutting member is tensioned.
- each end of the tensionable cutting member is positioned between a stationary cutaway portion of the tensive cutting head and a boss.
- the boss is a positioned so that the end of the tensionable cutting member is situated between the stationary cutaway portion of the tensive cutting head and the boss. The end of the tensionable cutting member is then secured or clamped between a lock screw and a flat of the boss.
- the tensive cutting assembly also includes a tensioning member.
- the tensioning member is operatively associated with the tensive cutting head to apply tension to the tensionable cutting member.
- Alternate means for tensioning the tensionable cutting member may include means attached to and operatively associating with the tensive cutting head such as mechanical means like machine heads, levers or levered cams, or hydraulic means.
- a tensioning member may be employed which is operatively associated with, but is not attached to, the tensive cutting head and which acts as a separate or stand alone unit, attaching to the tensive cutting head only during tensioning, and releasable after the tensionable cutting member is tensioned and the ends of the tensionable cutting members are secured.
