Definitions

  • the invention relates to a knife with a spiral cutting edge extending over approximately 150 to 360 °. This is divided into sections with different radius increases.
  • Such a knife known from DE-C-3 833 596 is used expressly for cutting material into slices, which tends to elastic and / or plastic deformation when a certain cutting pressure is exceeded.
  • the knife is arranged on a shaft oriented perpendicular to its plane and is driven by it about an axis of rotation essentially parallel to a longitudinal axis of the material.
  • the cutting edge of the known knife is divided into three sections, of which the first and third sections each run in the knife rotation direction with an increase in radius which is smaller than an increase in radius of a second section of the cutting edge arranged between them.
  • the known knife achieves the task of adapting the feed speed of the respectively active section of the cutting edge to the particular tendency of the material to be cut to deform at a constant knife speed.
  • the size of the feed rate is therefore increased or reduced in inverse proportion to the tendency of the material to deform.
  • a good to be sliced consists of a tendency to deform and a rigid good portion, such as a chop strand made of meat and bone
  • the known knife described above is unsuitable for its processing.
  • the knife first cuts through the portion of the good that tends to deform exclusively, for example meat from the pork chop strand, and then, with the decrease in this share of good and the rigid portion of good, for example bone, finally only this.
  • the rigid portion of the material also does not tend to deform when the knife exits, as occurs, for example, in boneless meat and sausage products at this cutting stage and leads to geometrically irregular slices.
  • a knife is known, the cutting edge of which can be subdivided into a first section with large toothing, a second toothless section and a third section, which in turn is toothed.
  • This last section has an increase in radius, and when a chop strand is cut, the chop strand is chopped.
  • the invention has for its object to design the known knives described above so that they are particularly suitable for cutting material into slices, if the material, such as a chop strand, from deformation-sensitive and rigid components, such as meat and bone , consists.
  • the disks separated from a strand of material with the knife according to the invention have a smooth cut surface over the most essential part of their area consisting of soft material and an equally smooth sawing surface over the most essential part of their area consisting of hard material.
  • the cutting edge provides an embodiment of the invention to extend the toothed section of the cutting edge over an angle of 80-190 °, preferably of 165 °.
  • a knife designed according to this embodiment leads to an optimal use of the two differently designed cutting edge sections in the case of pork chops with customary cross-sectional dimensions.
  • the format of the knife is usually kept as small as possible for technical as well as economic reasons. Regardless of the size of the angles over which the toothless and toothed section of the cutting edge extend, the length ratio between the toothless and toothed section of the cutting edge also varies as a result of the different increases in radius.
  • the toothed section of the cutting edge can also be chosen to be particularly large, and consequently the radius increase can be kept particularly small.
  • the cutting edge teeth move the bone material out of the way in the knife rotation direction, just as the knife penetrates into the bone area. The required driving force of the knife and its stress are correspondingly low.
  • a spiral knife 1 sits on a drive shaft 2, which is arranged parallel to the longitudinal extent of a magazine 3.
  • the knife 1 covers the entire cross section of the magazine 3 in each of its revolutions, in which a chop strand 4 is axially displaced with feed devices (not shown).
  • the extension of the bone 7 does not go beyond the hatched cross-sectional area 9 of the magazine 3 in the case of cutlet strands 4 with the usual cross-sectional dimensions, so that the bone 7 is severed entirely by means of the toothed section 8 of the cutting edge.
  • the toothed section 8 of the cutting edge runs with a minimal increase in radius according to a cosine function and thus prevents an abrupt stress on the bone 4 despite the high cutting performance of the knife 1, so that the bone 4 does not splinter but is sawn up smoothly.
