Definitions

  • the present invention generally relates to methods and equipment for cutting food products, and shapes of food products produced thereby.
  • Model CC® machines are centrifugal-type cutting machines capable of producing uniform slices, strip cuts, shreds and granulations of a wide variety of food products at high production capacities.
  • Model CC® machines generally comprise one or more knife assemblies arranged in sets spaced around the circumference of a cutting head.
  • FIGS. 7 through 9 represent knives 50, 52 and 54 recently developed to produce julienne cuts with machines such as the aforementioned Urschel Model CC® machines.
  • Each of the knives 50, 52 and 54 comprises a large-amplitude shaped (corrugated) blade 56 suitable for producing large-amplitude shaped food products, including shaped shredded and shaped strip-cut food products, nonlimiting examples of which include those disclosed in U.S. Design Patent Nos. D711068 and D704919 .
  • the profiles of these blades 56 when viewed from their leading edges 60, resemble a wave pattern, while secondary blades (tabs 58) are shown as located at the peaks 62 of these waves to produce a desired julienne cross section.
  • the leading edge 60 of the blade 56 cuts a slice off of a food product, followed by the julienne tabs 58 that cut the slice into strips.
  • the leading edges of the tabs 58 represented in FIG. 7 are located behind the leading edge 60 of the blade 56 and the tabs 58 extend to the trailing edge of the blade 56.
  • Relatively narrow julienne tabs 58 are represented in FIG. 8
  • relatively narrow staggered julienne tabs 58 are represented in FIG. 9 .
  • the tabs 58 of FIG. 7 are also represented as each having a height from a surface of the blade 56 to the outermost extent of the julienne tab 58 that is a maximum in proximity to the leading edge 60 of the blade 56 (corresponding to the leading edge of the tab 58) and continuously tapers to a minimum at or adjacent the trailing edge of the blade 56 (corresponding to the trailing edge of the tab 58).
  • tabs 58 of FIGS. 7 through 9 may be modified to have any shape or size suitable for cutting the food product slices into strips. While shown as located only on the peaks 62, it is foreseeable that tabs 58 could be additionally or alternatively located in the valleys 64 of the blades 56.
  • An advantageous aspect of the knives 50, 52 and 54 of FIGS. 7, 8 and 9 is the avoidance of the prior art practice of using a knife assembly comprising a shaped blade and a separate julienne knife.
  • the tabs 58 can be metallurgically joined to the blade 56 by any means known in the art, for example, brazing and/or welding, for example, laser welding.
  • the wider julienne tabs 58 represented in FIG. 7 are believed to be more securely attachable to the blade 56 than are narrower tabs 58 of the types represented in FIGS. 8 and 9 , as more surface area of each wider tab 58 is secured to the blade 56 relative to the narrower tabs 58.
  • wider tabs 58 may exert excessive forces on the food product slices.
  • the julienne tabs 58 are preferably constructed of the thinnest material possible while maintaining structural rigidity. Because the tabs 58 of sequential blades 56 are also sequential, it may be desirable to narrow (as in FIG. 8 ) and/or stagger (as in FIG. 9 ) the tabs 58, that is, at differing distances from the leading edge of the blade 56, to minimize the pressure between adjacent tabs 58.
  • the present invention provides knife assemblies of types suitable for producing julienne cuts in food products, including cuts of types that can be produced with the knives 50, 52, 54 and FIGS. 7, 8 and 9 .
  • the knife assemblies include a primary blade with at least one tab blade that is assembled with or formed from the primary blade without the need to fuse the primary and tab blades together.
  • a knife assembly adapted for producing julienne cut food product includes a primary blade having a corrugated shape to produce a large-amplitude food product.
  • the corrugated shape has a cutting leading edge and defining multiple peaks and valleys.
  • the primary blade further has slots located at least some of the peaks.
  • the knife assembly includes at least one tab blade adapted to cut the large-amplitude food product slice into strips.
  • the tab blade has a cross-sectional shape comprising a lower section that is complementary to a valley of the primary blade and comprising at least two bladed sections adapted to extend through at least two of the slots of the primary blade so as to be exposed above at least two peaks of the primary blade.
  • the primary and tab blades are not metallurgically joined together.
  • a method of producing julienne cut food products includes installing at least two sequential knife assemblies on a cutting apparatus.
  • Each of the knife assemblies have a primary blade having a corrugated shape to produce a large-amplitude food product and at least one tab blade adapted to cut the large-amplitude food product slice into strips.
  • the corrugated shape of the primary blade defines multiple peaks and valleys.
  • the primary blade further has slots located at least some of the peaks.
  • the tab blade has a cross-sectional shape comprising a lower section that is complementary to a valley of the primary blade and includes at least two bladed sections that extend through at least two of the slots of the primary blade so as to be exposed above at least two peaks of the primary blade.
  • the primary and tab blades are not metallurgically joined together.
  • the method includes operating the cutting apparatus to produce shaped shredded or shaped strip-cut food products.
  • a knife assembly adapted for producing julienne cutfood product includes a primary blade having a corrugated shape to produce a large-amplitude food product.
  • the corrugated shape has a cutting leading edge and defines multiple peaks and valleys.
  • the knife assembly includes at least one tab blade adapted to cut the large-amplitude food product slice into strips.
  • the tab blade is defined by a cut in the primary blade that forms a tab and then bending the tab so that the tab protrudes from the primary blade.
  • a method of producing julienne cut food products includes installing at least two sequential knife assemblies on a cutting apparatus.
  • Each of the knife assemblies include a primary blade having a corrugated shape to produce a large-amplitude food product and at least one tab blade adapted to cut the large-amplitude food product slice into strips.
  • the corrugated shape of the primary blade has a cutting leading edge and defines multiple peaks and valleys.
  • the tab blade is an extension of the primary blade produced by a cut section of the primary blade that is bent to protrude from the primary blade.
  • the method includes operating the cutting apparatus to produce shaped shredded or shaped strip-cut food products.
  • a technical effect of the invention is the ability produce to julienne cuts in food products without the need to fuse the primary and tab blades together or to assemble multiple blades.
  • FIG. 6 represents a knife assembly 28 of a type suitable for producing julienne cuts in food products, including cuts similar to the types that can be produced with the knives 50, 52, 54 of FIGS. 7, 8 and 9 .
  • the assembly 28 is particularly well suited for use in centrifugal-type cutting apparatuses, for example, the Model CC®, to produce uniform cuts in bulk quantities of food products.
  • the assembly 28 includes a primary blade 10 having a profile that, when viewed from its leading edge, resembles a wave pattern to produce large-amplitude shaped food products.
  • the assembly 28 further includes secondary "tab" blades 16 with bladed sections 18 (see FIG. 2 ) located at peaks of the primary blade 10 to enable the assembly 28 to produce shaped shredded and shaped strip-cut food products.
  • the assembly 28 also includes a knife holder 22 and a clamp 26 to keep the various components in place.
  • the primary blade 10 is equipped with tab slots 14 located at peaks 12 of its wave form, and through which the bladed sections 18 of the tab blades 16 extend and are aligned with the primary blade 10 without the need to metallurgically join the two components together.
  • FIG. 2 illustrates a nonlimiting embodiment of an individual tab blade 16 having two bladed sections 18 interconnected by a lower section 20 to yield a roughly U-shaped or V-shaped cross-section.
  • the shapes of the primary and tab blades 10 and 16 are complementary to enable the tab blade 16 to be placed beneath a valley of the primary blade 10 so that the two bladed sections 18 of the tab blade 16 individually extend up through two adjacent tab slots 14 of the blade 10.
  • FIG. 3 is an isolated view of the knife holder 22, which serves as the foundation of the knife assembly 28.
  • the knife holder 22 is similar to conventional knife holders of types used with the Model CC®, at least to the extent that the knife holder 22 is fabricated to have a surface contour with peaks and valleys complementary to the peaks and valleys of the primary blade 10, such that the blade 10 can be assembled with the holder 22 by placing the blade 10 on the holder 22 so that the peaks and valleys of its contour coincide with the peaks and valleys of the contour of the knife holder 22.
  • the knife holder 22 has been modified to include relief areas 24 within valleys of the holder 22.
  • the relief areas 24 are shaped and sized to accommodate the lower sections 20 of the tab blades 16, which are located between the knife holder 22 and the primary blade 10 in the assembly 28 of FIG. 6 .
  • FIG. 4 shows the knife holder 22 with the tab blades 16 appropriately placed in the relief areas 24 of the knife holder 22.
  • the lower section 20 of each tab blade 16 is completely received in one of the relief areas 24 of the knife holder 22, while the bladed sections 18 of each tab blade 16 extend away from the surface of the holder 22.
  • the relief areas 24 allow the knife holder 22 and the tab blades 16 in combination to define a contour that is complementary to the contour of the primary blade 10.
  • FIG. 5 shows the primary blade 10 placed on the subassembly of FIG. 4 .
  • the bladed sections 18 of the tab blades 16 remain exposed as a result of extending through the slots 14 in the blade 10.
  • FIG. 6 shows the completed knife assembly 28 following placement of the clamp 26 on the subassembly of FIG. 5 .
  • the finished knife assembly 28 is capable of providing uniform julienne cuts, similar or identical to cuts produced by the knife assemblies 50, 52 and 54.
  • the knife assembly 28 avoids the need to metallurgically join the tab blades 16 to the primary blade 10. Instead, the primary and tab blades 10 and 16 are secured together solely by the clamp 26 and the manner in which the blades 10 and 16 and the holder 22 are nested together as a result of their complementary contours.
  • FIGS. 10 and 11 Another possible embodiment of the invention is shown in FIGS. 10 and 11 .
  • a blade 30 that defines a primary leading edge 33 is modified to provide tab blades 32 without requiring welding or assembling the tab blades 32 with the blade 30 or other structure adapted to define the primary leading edge 33.
  • Each tab blade 32 is individually formed by making two contiguous cuts in the blade 30, a first of which starts at the trailing edge of the blade 30 within or adjacent a valley of the blade 30 and continues toward but short of the leading edge 33 of the blade 30. The second cut extends from the valley toward an adjacent peak, such that the second cut is set back a distance from the leading edge 33. The resulting tab is then bent upright at the peak where it remains attached to the blade 30, as evident in FIGS. 10 and 11 .
  • the tab blades 32 are functionally equivalent to the bladed sections 18 of the tab blades 16 of FIGS. 1-6 , in that the tab blades 32 are located at peaks of the blade 30 to produce shaped shredded and shaped strip-cut food products. As with the tab blades 16 of FIGS. 1-6 , the tab blades 32 of FIGS. 10 and 11 could be located within the valleys of the blade 30.
  • the tab blades 32 can be created to have square leading edges, for example, by cutting with a die or three-axis laser, or created to have beveled or angled leading edges, for example, using a laser with additional axes of rotation or a wire EDM. As with the assembly 28 of FIG.
  • the blade 30 can be used in combination with a knife holder 22 and a clamp 26 to secure the blade 30.
  • the first cuts may be configured to have varying lengths such that the tabs blades 32 of sequential peaks are staggered (as in FIG. 9 ), that is, at differing distances from the leading edge 33 of the blade 30, to minimize the pressure between adjacent tab blades 32.
  • FIG. 12 A further possible embodiment of the invention is shown in FIG. 12 .
  • This embodiment is similar to the embodiment shown in FIGS. 10 and 11 , with the primary exception that the tab blades 36 do not entirely extend to the trailing edge of the blade 34.
  • this embodiment requires at least a third contiguous cut that extends from the valley toward the adjacent peak, with the third cut spaced a distance from the trailing edge of the blade 34.
  • Methods of producing the blade 34 can be the same as those mentioned for the previous embodiment.
