Definitions

  • the invention relates to a shredding machine with at least one rotating shredding tool.
  • Such machines are widely used in the food, especially in the meat processing industry.
  • the material to be shredded for example meat and / or other parts of slaughter cattle, is fed into the shredding machine via a feed hopper normally present, in which it is then shredded in one or more shredding stages. It can occasionally happen that hard parts, for example coins, screws, any additional devices, meat hooks and the like, get into the machine.
  • a meat chopping machine has become known with which bone-free, minced meat is to be produced continuously.
  • Pre-shredded meat containing bone chips, cartilage and the like is fed to this machine.
  • the boneless meat is separated from the cartilage and the like in the machine and the two portions are discharged through different openings.
  • the entire filled product reaches the cutting rotor, which is not protected against damage when hard parts, in particular metallic parts, are added.
  • Another known shredding machine (DE-B-1 1 53 597) has a plate disk arranged coaxially to its cutting rotor with an angled edge and attached wings.
  • this disk is also not able to prevent the penetration of hard objects into the cutting area, rather it is their job to prevent inadmissible heating of the heat-sensitive comminution material in this area by an air cushion generated in the area of the bearing.
  • the object of the invention is to develop a shredding machine with at least one rotating shredding tool so that undesired hard objects not belonging to the shredded material can be removed before the shredded material enters the cutting area in order to avoid damage to the shredding tool (s) in particular.
  • a comminution machine with at least one rotating comminution tool which according to the invention is designed in accordance with the characterizing part of the first claim.
  • the centrifugal disc rotates at the same, preferably high speed as the latter due to its rotationally fixed connection to the drive shaft of the shredding tool.
  • the comminuted material is rotated as soon as it gets into the effective area of the centrifugal disc.
  • the heavier parts e.g. metal objects, etc.
  • the heavier parts e.g. metal objects, etc.
  • the lighter comminution material passes through the openings of the centrifugal disc and then reaches the area of the comminution tool or the cutting set following in the direction of passage.
  • the latter usually consists of a knife with two blades in particular and a perforated disc.
  • a particularly preferred embodiment of the invention provides that the centrifugal disc is connected upstream of the first comminution tool or products in the direction in which the comminution material passes. Objects carried in the comminuted material are thus removed from the comminuted material before reaching the comminution tool or the first comminution tool of the first cutting set. Damage to the comminution tool or cutting sets and, if present, the so-called jam fingers, which are connected upstream of the comminution tools in the direction of passage, are thereby avoided with certainty.
  • the comminution material reaches the centrifugal disc in front of the jam fingers. When the shredded material has left the shredder and the latter has been switched off, the centrifugal disc also stops, and then the metal parts contained therein can be cleaned. Like., which may be embedded in a remainder of the comminution, take out.
  • the catch groove is in a development of the invention on the outer edge of the centrifugal disc. This outer edge can close so tightly with a housing passage that the comminuted material and in particular the objects carried in an undesired manner cannot get past the outside of the centrifugal disc.
  • the catch groove is molded onto the centrifugal disc, in particular it is formed by the bent outer edge of the slinger.
  • the centrifugal disc and the drive shaft are expediently connected via a spline connection or the like, which simplifies assembly and reliably ensures the transmission of power.
  • the comminution machine according to the invention has an in particular funnel-shaped inlet 1, via which the material to be comminuted and any entrained hard objects to be separated out with the aid of the inventive design of the comminution machine enter the interior of the machine.
  • the comminution material is comminuted in one or more stages by means of at least one cutting set 2 and it leaves the machine in the direction of arrow 3.
  • the or each cutting set in the exemplary embodiment consists of a rotating, preferably double-bladed cutting knife 4 and a perforated disc 5. The latter is shown in FIG held in the axial and radial directions in the machine housing 6.
  • the cutting knife is non-rotatably coupled to the drive shaft 7, the shaft end 8 of which is only partially shown, is non-rotatably connected to a drive motor, not shown.
  • the connection between the drive shaft and the cutting knife 4 takes place via a spline connection 9.
  • centrifugal disc 11 On the spline 10, a centrifugal disc 11 with a catch groove 12 is rotatably and immovably placed. Seen in the direction of travel 13 of the comminution material, not shown, the centrifugal disc 11 is located in front of the cutting set 2 or its cutting knife 4 and also in front of so-called jam fingers 14. After this centrifugal disc hard objects which are undesirably carried in the comminution material can be separated, both are the jam finger 14 and the cutting set (s) are well protected against damage caused by such items.
  • the catch groove 12 is located on the outer edge of the centrifugal disc 11, to which it is preferably molded. Practically nothing can pass through the narrow gap space 15 because it is dimensioned such that it is always kept closed by the incoming goods. As a result, the comminuted material has to pass through the openings 16 of the centrifugal disc 11. These breakthroughs are kept comparatively large and only relatively narrow webs formed in the manner of spokes remain between them. As a result, the passage to the cutting set or sets is hardly reduced by the use of the centrifugal disc 11 1.
  • edge 17 of the centrifugal disc facing the incoming material is pulled slightly deeper inwards than the outer edge 18 of the openings 16.
