Abstract: Apparatuses for cutting food product are provided having a cutting head. The cutting head includes one or more knife assemblies. Each knife assembly includes a knife extending toward the food product and is adapter to secure the knife to the cutting head. The knife has a corrugated shape to produce a food product slice with generally parallel cuts wherein the food product slice has a periodic shape and a large-amplitude cross-section.

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.

Abstract: A furnace, a crucible for such a furnace, and a method for preparing and using the crucible. The crucible is formed of a nonmetallic refractory material to have side walls, a base wall, an opening in the base wall, and an interior cavity. A particulate refractory material is packed beneath the base wall and around the side walls of the crucible, and a gas diffuser is positioned beneath the crucible. A solid sintered porous barrier is formed within the opening in the base wall of the crucible and between the gas diffuser and the interior cavity of the crucible. The porous barrier is sufficiently porous to enable a gas exiting the diffuser to flow therethrough and enter the interior cavity of the crucible.

Abstract: An apparatus and method for slicing food products, and particularly soft, pliable food products susceptible to being deformed to the slicing process. The slicing apparatus includes a slicing wheel assembly and device for stabilizing the food product as it is being fed through the slicing wheel assembly. The slicing wheel assembly includes a hub, a rim circumscribing the hub so as to define an annular space therebetween, and arcuate blades extending between and removably attached to the hub and rim. The hub, rim, and blades lie in a cutting plane of the slicing wheel assembly. Each blade has an arcuate cutting edge on a convex portion thereof, with radially innermost and radially outermost extents of the blade that do not lie on the same radial of the slicing wheel assembly.

Abstract: A cutting apparatus having an annular-shaped cutting head and an impeller assembly coaxially mounted for rotation within the cutting head to deliver food products radially outward toward the cutting head. The cutting head has at least one knife extending radially inward toward the impeller assembly. The impeller assembly is equipped with paddles, each having a radially outer extremity adjacent the impeller assembly, a radially inner extremity, and a face therebetween facing the rotational direction of the impeller assembly. According to preferred aspects of the invention, removable posts radially extend from the radially outer extremity of each paddle, and/or the face of each paddle has grooves transverse to a radial of the impeller assembly.

Abstract: A cutting apparatus having an annular-shaped cutting head and an impeller assembly coaxially mounted for rotation within the cutting head to deliver food products radially outward toward the cutting head. The cutting head has at least one knife extending radially inward toward the impeller assembly. The knife has a cutting edge at a radially innermost extremity and a radially outer face that defines a trajectory plane for slices removed from the products by the cutting edge. The knife is clamped to the cutting head with a clamping feature that provides clearance for slices when traveling the trajectory plane of the knife.

Abstract: A process and apparatus for cutting food products, in which the products are individually delivered to a cutting device by causing the products to free-fall through a feed passage and then free-fall completely through the cutting means uninterrupted and entirely under the force of gravity. The food products are contacted and positioned as they drop through the feed passage prior to encountering the cutting device so as to produce size-reduced products of uniform size.

Abstract: An apparatus for cutting food product. The apparatus includes a cutting device and housing thereabove that defines a passage with an opening in proximity to the cutting device for delivering the food product to the cutting device. The apparatus is preferably adapted to cut food products in a substantially horizontal plane, and as such the cutting device is preferably oriented to make a substantially horizontal cut through a food product. A lower portion of the housing has a lower extremity that defines the opening of the passage. The apparatus is equipped with various features that improve the operation of the apparatus and the consistency of the sliced product, particularly if the delivered food product varies in shape and size and may contain embedded stones.

Abstract: An apparatus and process for cutting food products, in which the products are fed single-file by gravity through a cutting device comprising one or more cutting elements. The apparatus makes use of a device for contacting and positioning the products as they drop through a feed passage prior to encountering the cutting device so as to produce size-reduced products of more uniform size.

Abstract: A food product cutting apparatus that makes a substantially horizontal cut through food product being delivered in a substantially vertical direction. The food product is delivered to a cutting device through an internal passage of at least one feed member above the cutting device. A force is applied to the food product traveling downward through the internal passage so as to push the food product against a first wall of the feed member. The apparatus is configured to improve product flow by configuring the passage of the feed member to have a cross-sectional shape defined by two offset, overlapping diameters. The apparatus is also configured for improved safety by ensuring that the cutting device is properly secured before electrical power is available for driving the cutting device.
