A cutting unit for recovering gluten from a mixture containing starch and gluten, having a housing in which is formed a cutting chamber having an inlet and an outlet. A first shaft, which is mounted in a rotatable manner in the housing, has a multiplicity of first disc-like cutting tools, which are fitted in a rotationally fixed manner on the first shaft, wherein in each case two adjacent cutting tools of the multiplicity of first cutting tools are spaced apart from one another axially to form an interspace. A second shaft, which is mounted in a rotatable manner in the housing is arranged parallel to the first shaft and has a multiplicity of second disc-like cutting tools, which are fitted in a rotationally fixed manner on the second shaft, wherein in each case two adjacent cutting tools of the multiplicity of second cutting tools are spaced apart from one another axially to form a further interspace. The first and second cutting tools are arranged in the cutting chamber, wherein the first and the second shafts are spaced apart from one another radially, and the multiplicity of first cutting tools are offset axially relative to the multiplicity of second cutting tools, such that at least one portion of one of the multiplicity of second cutting tools engages in an interspace. A respective gap having a width of at least 0.3 mm is formed in the axial direction between the at least one engaging portion and the two adjacent, interspace-forming first cutting tools.

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.

Provided are a shredder assuring greater freedom in designing a feedstock supplier that supplies sheets, and a sheet manufacturing apparatus. The shredder has a feedstock supplier having a supply opening through which a sheet is supplied; and a shredding device configured to shred the sheet supplied from the feedstock supplier. The shredding device includes a rotary cutter that rotates on a first axis, and a circulating cutter that moves in an endless path and cuts the sheet in conjunction with the rotary cutter. The circulating cutter includes a conveyor configured to convey the sheet from the feedstock supplier to the rotary cutter.

A medical waste processing device includes an outer housing, material intake chamber having a passageway through which material passes, and cutting members contained within the housing that cuts and shreds the waste material before entering a waste receptacle that is located in the lower portion of the housing. A vacuum filter system is further provided to capture and filter potentially harmful aerosols that may be emitted during operation of the device. A method is also provided for reducing the volume of waste material through operation of the electrical shredding device.

A plant vine chopper rotor drum assembly has a plurality of rotor rings spaced along, encircling, and attached to the longitudinal outer surface of a rotatable main drum tube. Each rotor ring has one or more pairs of angled mounting tabs that alternate to the left and to the right to the general plane of respective rotor ring; and the rotor rings are distributed in a cutting zone along and surrounding the longitudinal rotational axis of the drum tube with each mounting tab having a generally planar cutting blade attached. The angled blades distributed around the outer circumference of the ring cooperate one with another during operational rotation of the drum to guard each blade and the drum against the wrapping of clogging fibrous strands and other clogging material around the drum.

An apparatus for removing flexible material from rotating equipment includes a cutter assembly integrated into the rotating equipment. The cutter assembly includes a cutter shaft, a cutter blade coupled to the cutter shaft, and a movement mechanism configured to move the cutter assembly along an axis of the rotating equipment to cut accumulated material from the rotating equipment.

A dual-shaft shredder for comminuting solids or solids in liquids comprises a housing defining an interior comminuting space, an inlet opening, an outlet opening, and a first and second cutting disc block each having a plurality of cutting discs disposed on a hub body such that an intermediate space is present between each two adjacent cutting discs. Some of the first cutting discs each engage in the intermediate space between two adjacent second cutting discs and some of the second cutting discs each engage in the intermediate space between two adjacent first cutting discs. A first shaft stub and a second shaft stub extend into an axial recess of the first and second cutting disc blocks for transmitting torques, and a first clamping device and a second clamping device clamp the shaft stubs against the cutting disc blocks.

An impact cutter blade and holder system is disclosed. The impact cutter blade and holder system includes: a cutter disk, a plurality of impact holders, and a plurality of impact cutter blades. The cutter disk has a central axis about which the cutter disk is configured to rotate. The plurality of impact holders are secured to the cutter disk. The plurality of impact cutter blades is secured to the plurality of impact holders.

A mincer includes a housing, a hinged door, a handle, a cam, an axle, and a plurality of circular blades mounted on the axle. Rotation of the handle or knob with respect to the housing causes rotation of the cam with respect to the housing, which in turn causes the axle and the blades mounted thereon to travel radially outward or inward with respect to the housing to extend or retract the blades out of or into the housing. The mincer can be operated to extend the blades for operation and to retract the blades for storage. The door can be closed for operation and opened for cleaning of the mincer.
