Abstract: An impeller for use in a food cutting apparatus. The impeller is adapted to be mounted coaxially within a cutting head having one or more cutting knives disposed about a circumference thereof. The impeller is equipped with paddles such that, as the impeller rotates within the cutting head, the paddles force food product radially outward toward the stationary cutting knives of the cutting head. The paddles are equipped with grooves on at least one face thereof. The grooves preferably extend across the entire surface of the paddle face for the purpose of promoting the stability of the food product relative to the impeller.

Abstract: An apparatus for cutting food product includes at least one knife having longitudinal ends and a hollow spindle. The knife has a central region therebetween and a base and opposite sides located along a longitudinal extent thereof. The hollow spindle has a slot for receiving the knife. The slot has a base wall for engaging and supporting the base of the knife and side walls for engaging and supporting the sides of the knife. The spindle includes a circumferential wall in which at least two circumferential gaps are present to segment the wall into at least two end wall segments and a third wall segment therebetween. The gaps separate the slot into at least two end slot segments and a third slot segment therebetween that are complementary to and receive, respectively, the base and side walls of the knife at the longitudinal ends and central region, respectively, of the knife.

Abstract: A material reduction apparatuses and methods suitable for performing cutting operations on a variety of materials, including food and nonfood products. The apparatus includes a machine having a cutting head, an impeller adapted for rotation within the cutting head about an axis thereof, means disposed on the cutting head for reducing the size of a material forced therethrough by the impeller, and an electric motor unit disposed in-line with the axis of the impeller. The electric motor unit supports the cutting head and impeller and has a shaft coupled to the impeller to rotate the impeller within the cutting head. The apparatus further includes means physically coupled to the electric motor unit for supporting the machine within a duct in which the machine is entirely enclosed. The supporting means includes arms that extend from the electric motor unit.

Abstract: Knife assemblies and methods therefor that are adapted to be used with a cutting apparatus capable of producing a variety of shaped food products having large amplitudes, for example, sliced, shredded, and strip-cut food products. The knife assembly is adapted for cutting food product includes a knife having a corrugated shape to produce a large-amplitude food product slice having a periodic shape and at least one julienne tab metallurgically joined to the knife adapted to cut the food product slice into strips.

Abstract: Method and apparatus for reducing food products. The apparatus includes a casing, an impeller adapted for rotation within the casing, and a cutting device. The casing has axial and circumferential openings for product entering and exiting, respectively, the casing. The impeller includes a drum, paddles mounted to the drum, and pockets defined by and between adjacent pairs of paddles that are radially aligned with the circumferential opening of the casing as each pocket travels past the circumferential opening. The cutting device includes a knife disposed at the circumferential opening of the casing and oriented perpendicular to the axis of the impeller. The knife lies on a sector of the casing and has a cutting edge located within an interior of the casing so that the knife extends into the path of the paddles and passes through relief slots defined in the paddles as the impeller rotates.
