  • Publication number: 20160243716
    Abstract: A cutting machine for cutting a vegetable product includes a multi-knife cutting plate mounted in-line along a product flow path and a drive motor, whereby the cutting plate moves in an orbital motion in a plane substantially perpendicular to the flow path, thereby moving the cutting knives sequentially and repeatedly across the product flow path. A system for cutting vegetable products includes a transport system configured for transporting vegetable products in single file toward an outlet, a plurality of cutting machines, a collection system disposed downstream of the cutting machines and configured to collect the vegetables after cutting, and a selection device configured to selectively couple the outlet of the transport system to one or more of the cutting machines. The plurality of cutting machines may be mounted upon a transport device to selectively move one of the cutting machines into communication with the outlet of the transport system.

  • Patent number: 9352479
    Abstract: A cutting machine for cutting a vegetable product includes a frame, supporting a product flow path, at least three links, pivotally attached to the frame, a cutting plate, pivotally attached to each of the three links at three pivot points and oriented substantially perpendicular to the flow path, a plurality of cutting knives, carried by the cutting plate, each having a generally corrugated configuration defining adjacent peaks and troughs, the cutting knives oriented angularly with respect to each other, and a drive motor, coupled to rotationally drive at least one of the links with respect to the frame, whereby the cutting plate moves in an orbital motion in a plane substantially perpendicular to the flow path, thereby moving the cutting knives sequentially and repeatedly across the product flow path.

  • Publication number: 20160029674
    Abstract: A ricer plate for use in a ricing system configured for forcing cooked potato pieces, including potato peel and potato starch, against and through the ricer plate, includes a plate, having a thickness, a center and a perimeter. A plurality of substantially linear, elongate slots are disposed in the plate, extending through the thickness of the plate. Each slot is aligned at an angle relative to a radial line extending from the center, and has a width of at least about 1/10 inch and a length that is at least about three times the width. The slots are suitably shaped to pass a portion of potato peel with the potato starch.

  • Publication number: 20160016326
    Abstract: A rotary knife fixture configured for use in a water knife cutting system includes a ring, defining an internal aperture, and at least two spaced, angularly offset, parallel groups of parallel helically twisted cutting blades, extending across the aperture. The ring is configured to be placed in fluid communication with a hydraulic feed conduit of the water knife cutting system and for rotary motion about a rotational axis extending through the aperture. The groups of parallel blades are oriented generally perpendicular to the rotational axis. Each cutting blade has a sharpened cutting edge at one side thereof and is twisted generally about a center point thereof to define a pair of cutting edges oriented in opposite-facing circumferential directions. A vegetable product, fed through the aperture at a product speed, and with the rotary knife fixture rotating at a rotational speed, is substantially simultaneously cut into multiple helically twisted pieces.

  • Publication number: 20150246456
    Abstract: 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.

  • Publication number: 20140360326
    Abstract: A cutting head for a food product cutting system includes a generally cylindrical rotatable body, having a radius and configured to rotate about an axis, and a plurality of spatially separated, generally parallel elongate cutting blades, arranged in a circular array centered on the axis and defining a perimeter of the body. Each blade has a long dimension and an outwardly-oriented cutting edge. The generally cylindrical rotatable body is connectable to a driving mechanism configured to rotate the cutting head about the axis, and is positionable adjacent to a food product delivery mechanism, whereby food product that contacts the cutting edges of the array of blades in a direction generally perpendicular to the axis is cut by the blades into slices having a repeatable curvature.

  • Publication number: 20140322396
    Abstract: A method for packaging a frozen food product includes placing a fluid food product into a flexible container, sealing the container and pasteurizing the food product in the sealed container. The method further includes applying a form to at least one surface of the flexible container, the form embossing the container and creating a series of compartments separated by thin segments therebetween, and freezing the product in the container with the form in place.

  • Publication number: 20080134850
    Abstract: A machine and process are provided for forming small, random sized potato pieces suitable for use in preparing potato hash browns and potato patties and the like. Blanched potatoes are chilled and then swept against a blunt edge resulting in shattering of each potato into relatively small, random-sized pieces. If desired, each blunt shatter-edge can be provided in a knife unit including one or more cross-cut knives to subdivide larger shattered pieces into a smaller size. The produced potato pieces are chilled as by freezing or by chilling to a refrigerated temperature for shipment and/or storage pending finish preparation.

  • Publication number: 20070193429
    Abstract: A knife blade in a fixture is provided for cutting vegetable products particularly such as potatoes, wherein the knife fixture includes a grid of knife blades adapted for producing product strips defined by rough-textured cut surfaces. Each knife blade includes a sharp cutting edge for smooth-surface cutting of products propelled hydraulically through the knife fixture. Each knife blade further includes opposed side faces each incorporating an array of shallow channels having an upstream end positioned rearwardly from the associated cutting edge and extending generally in the direction of product travel. These shallow channels disrupt and roughen the cut product surfaces to produce rough-textured cut surfaces. In French fry potato strips, this roughened surface texture results in enhanced surface crispness after frying, or alternately enhances batter pick-up and/or crispness characteristics in a batter-coated French fry product. Enhanced finished product hold time is also achieved.
