Abstract: Methods and apparatuses for reducing food products. Such a method includes introducing a food product into an impeller rotating within a casing about an axis thereof. The impeller has paddles and pockets defined by and between adjacent pairs of the paddles. The paddles are circumferentially spaced so that each pocket is sequentially radially aligned with a circumferential opening of the casing as the impeller rotates. Each paddle has a relief slot defined in an outer radial edge of the paddle. Food products are expelled from the pockets and cut with a knife disposed at the circumferential opening of the casing as the impeller rotates and the pockets travel past the circumferential opening. The knife defines a cord of the casing, extends into the path of the paddles, and passes through the relief slots of the paddles.

Abstract: An apparatus and method suitable for performing cutting operations on a product to yield a reduced-size product, for example, slicing, strip-cutting, dicing, shredding, and/or granulating a food product. The apparatus includes a casing, an impeller adapted for rotation within the casing about an axis thereof, and knives that perform, in sequence, slicing, strip-cutting and crosscutting on a product to produce reduced-size products. The apparatus is capable of performing a method by which a product is introduced into the impeller and the impeller is rotated to slice the product with a slicing knife and produce therefrom slices having peaks and valleys on opposite surfaces thereof and a cross-sectional shape that periodically varies in thickness. Strips are then produced from each of the slices by forming parallel cuts, each coinciding with a peak of each slice so that each strip has a width substantially identical to a wavelength of the slice.
