A cutting system for a grinding pump, including a cutting disc attached to the pump near an inlet and having a cutting surface with multiple cutting orifices, and a rotating cutter attached to the rotating shaft of the pump and having two cutting blades, each blade having a cutting edge on a forward-facing side of the rotating cutter. The rotating cutter is located on the upstream side of the cutting disc, and cooperates with the cutting orifices of the cutting disc to perform cutting actions. Each cutting orifice has a hole extending from the cutting surface through the cutting disc to form a feeding orifice, and a cutting protrusion protruding from the cutting surface and surrounding the hole region. The multiple cutting orifices define recessed areas of the cutting surface between the cutting orifices. The cutting system can prevent uncut floating matters from being trapped, and is effective and safe.

An apparatus for tearing meat is disclosed. The apparatus includes a gravity-fed hopper including at least one sidewall that forms a first opening configured to receive meat articles and a second opening configured to discharge torn meat articles. The apparatus includes a rotatable spindle element positioned at least partially within the hopper and downstream of the first opening. The rotatable spindle element includes a shaft having a longitudinal axis and a plurality of teeth coupled to the shaft, the teeth being spaced apart from one another. The apparatus includes a plurality of rods, which extend from the sidewall spaced apart from one another and which are interlaced with the plurality of teeth, and a motor coupled to the rotatable spindle element configured to rotate the rotatable spindle element to cause at least some of the plurality of teeth to rotate and pass between two different rods.

A portable grinding/shredding/chipping system with a drive track assembly which is manipulatable to facilitate altering the orientation of the portable grinding/shredding/chipping system. This arrangement results in improved loading and processing, of both long and short materials, as well as facilitates connection of a transport dolly and a transport truck/tractor without requiring any additional lifting mechanism. A pivotable housing provides greater access to the rotor and has an over-center arrangement which prevents the pivotable housing from inadvertently moving or pivoting back into engagement with the rotor. The portable grinding/shredding/chipping system is provided with a belt drive assembly which facilitates modification of the rotational speed of the rotor by merely replacing a sheave of the belt drive assembly. Lastly, both head and tail pulleys are driven by a respective motor so that a catinary of the discharge conveyor is radiussed which shortens an axial length of the system.

A grinder accessory is useful for a pump in a wastewater application. The grinder accessory has a cutter plate and a cutting body that co-act on solids, especially fibriform solids. The cutter plate has first and second planar faces, mounted in an inlet of the pump, with a plurality of through holes and a central aperture. The cutting body is poised atop the first planar face and extends through the central aperture to rotationally couple with a drive shaft of the pump. A central hub of the cutting body has a plurality of arms that extend radially proximate to the first planar face, so that a leading edge of the arms interacts with the through holes on solids passing therethrough. A housing defines a cutting chamber around the cutter plate and the cutting body to protect them and to induce swirling action.

A food recycler can include a case having a case volume between 8.79 liters and 35 liters, a control system, a user interface in electrical communication with the control system, and a bucket being configured with a bucket volume, wherein a ratio of the bucket volume to the case volume is between 0.0717 and 0.2857. The recycler can include a motor in communication with the control system, the motor being configured adjacent at least in part to the bucket, a gearbox configured below the bucket and in mechanical communication with the motor, a filter system having at least one filter and configured to receive air from a top portion of the bucket and a drying component configured to remove water from waste food items.

The disclosure relates to a device for shredding strip-shaped material comprising a housing with at least one feed opening for the strip-shaped material and a discharge opening for the shredded material, a blade holder which is mounted to be rotatable about an axis within the housing, at least one blade which is attached to the blade holder, at least one counter blade which is attached to the housing, and a drive configured to rotate the blade holder in a first direction of rotation and a second direction of rotation, opposite to the first direction of rotation, about the axis. The disclosure further relates to a method for operating a device for shredding strip-shaped material. Under the method, at least one blade holder mounted to be rotatable in a first direction of rotation, as well as in a second direction of rotation, is employed by the device.

A bone grinder is provided herein. The bone grinder may have a grinding chamber, an intermediate zone, and a primary cutting element and a secondary cutting element. The intermediate zone may have a first wall and a second wall within the grinding chamber, and the intermediate zone may separate the primary cutting element from the secondary cutting element. The first wall and the second wall may slope inward such that a distance between the first wall and the second wall generally decreases from the primary cutting element to the secondary cutting element. The primary cutting element and the secondary cutting element may be positioned within the grinding chamber to sequentially perform primary cutting operations and secondary cutting operations on a bone. A drive mechanism may operatively engage the primary cutting element and the secondary cutting element.
