The machine further includes an axial coupling and an annular cap. The axial coupling is defined by at least two parts, a first part arranged on the outlet of the discharge duct and a second part arranged on an interchangeable element that is part of a safety kit having at least two mutually different interchangeable elements. The first interchangeable element is compatible both with plates of the first type and plates of the second type as well as an integrated protection body; the second interchangeable element is compatible exclusively with the plates of the second type.

A disgregating device of biological material, comprising: a hollow outer body, defining an inner chamber; a fixed disgregating grid, having a plurality of microholes provided with sharp edges, and housed transversely in the inner chamber so as to define an upper loading chamber apt to be loaded with the biological material to be disgregated and a lower collecting chamber apt to collect the biological material, after it has been disgregated; and a bladed rotor, rotating in the inner chamber, apt to co-operate, rotating, with the fixed disgregating grid, so as to feed and bring the biological material, contained in the upper loading chamber, into contact with the microholes of the disgregating grid and therefore cause the disgregation of the biological material making it pass through these microholes.

An emulsion system is provided. The system includes a shaft that supports a plurality of cutting assemblies and screens in alternating order, wherein the cutting assembly rotates with respect to an in close proximity to the screen. The cutting assemblies include a plurality of cutting elements that extend radially outward from a hub and are positioned at consistent radial spacing along the perimeter of the hub. Each cutting element includes front and back edges that cut food particles in conjunction with holes within the screen, wherein the front and back edges are substantially perpendicular.

A mincing machine for mincing a product, in particular for mincing meat, includes at least one stationary hole plate and at least one rotating hole plate which interact to mince the product. The mincing machine has a rotating cutter head mounted on a shaft wherein said cutter head is arranged upstream of the interacting hole plates in the conveying direction of the product to be minced in order to interact with a stationary hole plate to mince the product.

A tissue mincer includes a canister defining a chamber and an opening, a lid configured to cover the opening, and a tissue cutter. The tissue cutter includes a shaft and a blade assembly. The shaft includes a proximal portion that is configured to be rotated and a distal portion extending into the chamber when the tissue mincer is assembled. The distal portion is coupled to the blade assembly. The blade assembly includes a first disk, at least one blade spaced from the distal portion of the shaft by the first disk, and a disk retainer that encloses at least a portion of the blade. The blade can rotate relative to at least the first disk when the proximal portion of the shaft rotates. The blade includes at least one cutting edge that is configured to cut tissue as the blade rotates.

A food grinder comprises a base housing a motor, a throat portion coupled to the base, a receiving tube coupled to the throat, a feeding tray coupled to an upper end of the receiving tube, a selectively rotatable auger selectively insertable into and removable from the throat portion, and a storage tray sized and shaped to be selectively insertable into and removable from the feeding tray. The storage tray comprises a main body having a plurality of depressions formed in a top surface thereof. Each depression is sized and shaped to hold one or more accessories for use with the food grinder.

A cutting knife for a rotating emulsion system is provided. The knife includes a body with a bottom surface and a leading portion, the bottom surface and the leading portion collectively form a cutting edge. The body further comprises a portion that is configured to be inserted within a slot within a cutting assembly with the bottom surface and a portion of the leading portion extending outward from the slot, the cutting assembly configured to be rotated by a shaft that extends through a center hole in the cutting assembly and is fixed to the cutting assembly, wherein the leading portion is a surface of the body that faces the direction of rotation of the body as the cutting assembly is rotated, The cutting edge and the leading portion each form a plurality of serrations along at least a portion of a length thereof.

The present invention relates to a super absorbent polymer and a method for preparing the same. The present invention has features that it is possible to prepare a super absorbent resin that can have an improved centrifuge retention capacity (CRC) and a high absorbency under load (AUL) by controlling the shape and size of the chopper die holes during coarse pulverization of a hydrous gel phase polymer.

An embodiment described herein provides for a system for removing or installing a grinder plate. The system includes a grinder plate having a disk shaped body which defines a central cylindrical aperture extending therethrough and a first one or more screw threads are defined in the central aperture. The system also includes a plate handling tool having an elongated body defining a second one or more screw threads on an external surface proximate the first end. The first one or more screw threads of the plate are configured to mate with the second one or more screw threads of the tool.

A grinding machine includes first feed screw, first head, first center pin, first knife assembly, bushing and first orifice plate. Second feed screw is coupled to first center pin and rotates within second head. Second feed screw is positioned against the bushing such that the bushing acts as a thrust bearing. Second center pin is coupled to second feed screw and is configured to rotate a second knife assembly. Second orifice plate is arranged on second center pin. Second mounting ring can be linearly adjusted relative to second head to axially position second orifice plate between a stop shoulder of second head and a lip of second mounting ring. Second feed screw may include a plurality of flights arranged in a split flight configuration including one or more ingress end flights and one or more egress end flights.
