Definitions

  • the invention relates to semi-solid, plastic and plastoelastic biological raw materials finely comminuting devices with at least one conveyor for the raw materials and at least one downstream comminuting the raw materials device with a perforated disc after at least one rotating knife.
  • the mincing of meat or other biological materials which from a purely procedural point of view represents a rotary shear cut between fixed perforated disc and rotating knife, is to be characterized on the one hand as ingenious, on the other hand as very problematic active principle. Ingenious because it manages to shred large quantities of product evenly and continuously.
  • the problem with the Wolfen compared to the knife cut is the naturally higher compression of the product and the friction occurring in the cutting set during comminution.
  • EP 2 338 602 A2 is a Vorschneider- or perforated disc for multi-part cutting sets known.
  • An attempt is made to increase the performance of wolf machines by cutting edges located in the bores in the direction of flow.
  • the problem here is the not inconsiderable manufacturing costs for these discs and the risk of breakage of longitudinally integrated cutting edges. This also increases the risk of product contamination with metal particles.
  • the publication FR 1 306 039 A includes a chopping machine, the perforations in lattice wafers cooperating with rotating knives being in the form of openings of elongate profile, which are obliquely oriented from the center of the pane toward the periphery of the pane in the direction of the knife movement.
  • a Fleischschnetzelmaschine wherein at the outlet side of a perforated disc, a knife is rotatably arranged.
  • the meat product conveyed through the perforated disc is cut into pieces with the knife.
  • the holes in the perforated disc may be formed angular or circular arc-shaped.
  • a piece-shaped Schnetzelgut is achieved, which not only facilitates cooking, but is softer when eating.
  • the publication DE 102 48 185 A1 discloses a butcher machine, wherein in the housing in the region of a worm cylinder, a sealing screw is arranged.
  • a sealing screw is arranged in the housing in the region of a worm cylinder.
  • the publication DD 277 399 A1 shows a perforated disc for cutting sets of a meat grinder.
  • the perforated disc has a certain area ratio of drilled to undrilled surface.
  • the openings are circles or designed in such a way that a pulling cut is present during the comminution process.
  • the publication US 3 298 411 A includes a shredding device with perforated discs with differently designed holes.
  • the latter are in particular Circles or triangles.
  • In conjunction with rectilinear knives rubs the material to be shredded when cutting at the hole edges.
  • the specified in claim 1 invention has for its object to reduce the occurring during the grinding of semi-solid, plastic and plastoelastic biological raw materials occurring compression and the friction occurring during crushing.
  • the semi-solid, plastic and plastoelastic biological raw materials finely comminuting facilities with at least one conveyor for the raw materials and at least one downstream comminuting the raw materials device with a perforated disc after at least one rotating blade, are characterized in particular by the fact that occurs during grinding of the raw materials compression and the friction occurring during comminution is reduced and / or controlled.
  • a hole edge of at least one hole of the perforated disc and the cutting edge of the knife are designed to be identical to each other and / or one or the hole edge of at least one hole and the cutting edge of the knife in the cutting direction at an angle equal to / greater than 80 ° and less than or equal to 100 ° to each other.
  • the raw materials are finely crushed.
  • a continuous cutting system for semi-solid, plastic and plastoelastic biological raw materials is realized, which operates on the principle of rotating shear cut.
  • the raw materials are, for example, foods such as meat, fish or vegetables, either raw or cooked.
  • the device is thus suitable for machines that work on the principle of meat grinder.
  • the finely comminuting device consists of at least one combination of rotating knife and fixed perforated disc.
  • the associated energy consumption and the expected cutting quality, the angle of incidence of the cutting edge on the raw material is of decisive importance.
  • the lowest energy consumption and the best cutting quality is achieved with a vertical appearance of the respective cutting edge on the product, since less friction and thus less product crushing occur.
  • the intensity and efficiency of a cutting process depends, among other things, on the cutting edge length.
  • Circular openings in the perforated discs thus have two very significant disadvantages.
  • a circle describes a surface with the smallest circumference compared to other shapes.
  • the cutting edge length in conventional perforated discs of wolf machines is a minimum.
  • the angle of incidence between raw material and tools in the form of knife and hole edge is only right-angled at one point. This increases the energy consumption and the cutting quality decreases.
  • the device is characterized in particular by the fact that instead of circular openings / bores in perforated disks for wolf machines openings are introduced with a different cross-sectional shape.
  • the holes and the cutting edge of the knife are identical to each other. This concerns in particular the hole edge to which an area of the cutting edge of the knife is moved during the cut. This hole edge is thus arranged corresponding to the region of the cutting edge.
  • areas of the cutting edge of the knife and hole edge are formed so that during rotation of the Messers above the perforated disc each have at least two points of the cutting edges of the edge of the hole and rotating blade parallel to each other in the direction of force.
  • the perforated disc has according to the embodiment of claim 2 in hole circles or spirally arranged slots, which are further in the hole circles or the spiral equidistantly adjacent or offset from each other.
  • the cutting edge is extended, so that thus increases the cutting intensity.
  • the throughput is increased and the cut quality is improved.
  • the latter is particularly important for the production of minced meat for fresh marketing or raw sausage production. Lower cell crushing and destruction improves the shelf life and hygiene of the product.
  • the slots are thus arranged radially from the center or in a staggered arrangement is not radially in the perforated disc.
  • a staggered arrangement one-sided loads of drive as motor and tools are avoided as hole edges and cutting edge.
  • the elongated holes are according to the embodiment of claim 3 in cross-section kidney-shaped slots, which are arranged facing outward in the longitudinal direction. In outwardly facing such slots results in an arcuate cutting edge.
  • the cutting edge of the knife and a hole edge of the elongated hole are arranged correspondingly extending to each other during shearing.
  • at least two points of the cutting edges of the slot and the rotating blade are parallel to each other in the direction of the force. The cutting edge of the holes is extended and thus increases the cutting intensity.
  • the slots are according to the embodiment of claim 4 rectilinear elongated holes, which are arranged pointing radially outward.
  • One or the hole edge of at least one hole and the cutting edge of the knife are arranged according to the embodiment of claim 5 in the cutting direction at an angle equal to / greater than 85 ° and less than / equal to 95 ° to each other. Is particularly advantageous an angle close to or equal to 90 °, so that no and / or minimal friction when crushing the semi-solid, plastic and plastoelastic biological raw material is present.
