A secondary shredder can include a rotor assembly that employs a modular rotor design. Each rotor of the rotor assembly can include a number of blades that are symmetrical around a horizontal and a vertical axis. Each rotor can include a number of radial extensions forming gaps into which the blades insert. The blades can be secured within the gaps by wedges that apply an inward force against the blades when the wedges are secured into the gaps. The radial extensions and blades can include keyways into which keys insert to prevent the blades from escaping the gaps. The secondary shredder may also include a stationary knife assembly that includes multiple stationary knives that are positioned on the same side of the rotor assembly.

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.

A drum for a precision chipper, said chipping device comprising: a shaft on which the drum is arranged, wherein cutting tools are provided on the outer circumference of the drum in blade holders, which cutting tools are used to chop the material to be chipped; at least one distancing piece, which has a support surface or contact surface for the material to be chipped on the drum, the height of which distancing piece being used to determine the chip size, wherein the vertical position of the distancing piece on the drum can be set or adjusted. The distancing piece, when viewed in cross-section, has an approximately T-shaped form such that it can be placed on the outer edge of the drum disk by means of a positively locking surface of the distancing piece, said surface being formed on the face pointing towards the drum by the inner radius of the distancing piece.

A device for shredding deep-frozen food products provided in block form comprises a tool which is rotated around an axis of rotation (X) and advanced towards the block, thereby scraping off layers from the block. The device comprises two drive motors for generating rotational and feed movements of the tool, which can be controlled separately, at least one being of variable-speed. The device also includes a gear arrangement coupled to the drive motors in such a way that only one of the drive motors rotates the tool and other drive motors together serve to feed the tool, in a way that at a certain rotational speed ratio of the two drive motors the tool is rotated without axial movement of the latter and, at other rotational speed ratios advancing or retracting movement of the tool along the axis of rotation (X) occurs.

A food recycler includes a case, a control system within the case, and a set of user interface components that are usable to at least cause the control system to initiate a food recycling cycle. The food recycler also includes a motor within the case and a bucket that has a volumetric capacity between 2.51 and 10 liters. A filter system configured to accommodate air filters is also included in the case of the food recycler. To remove water from waste food items, the food recycler includes a drying component.
