Definitions

  • the invention relates to a perforated disc-knife combination for cutting sets from Meat grinders and for wolf-like shredding machines, whose screw conveyors are rotatable are stored in the pressure housing and are equipped with single or multi-part cutting sets.
  • the simplest form of a cutting set for meat grinders consists of one in the cutting housing of the mincer and one of the perforated disks revolving knife, which protrudes from the axis of the screw conveyor Knife pin is driven. By arranging several knives and The multi-part cutting sets result from perforated disks.
  • the through holes in the perforated disks are made according to different systems in the perforated disk bodies and, depending on the position on the surface of a perforated disk, take part in the absorption and conveyance of the wolf material in different ways. This is due to the fact that the bores are distributed over the entire diameter of the perforated disk and are therefore provided in different coordinates and are also in different ways related to the cutter bars of the respectively assigned cutter. Due to the different position and the different pressure build-up in the raw material, different production processes arise in the individual bores or segment sections of an entire perforated disc.
  • the perforated disks used have the task of picking up the material to be processed in the holes in the perforated disk, compressing it, clamping it and acting with the bore edges as counter-cutting edges for the rotating knife, in order to enable the cut.
  • tool steels and stainless steels are used in the hardened state from 50 HRC up to 62 HRC for the perforated disks.
  • the choice of material and the density of the coating, the number of through holes in the respective perforated disk are of essential importance for the throughput of the material to be mined through the respective perforated disk and thus a quality feature for the entire cutting set.
  • the DD 277 399 is concerned with the problem of an optimal occupancy density of perforated disks with corresponding through holes. It is shown that the area ratio of drilled to undrilled area has a value of 0.2 to 0.3, the degree of coverage should correspond to a value ⁇ 60 to 80%, the webs forming a system of secondary cutting edges and the width dimension of such a design Perforated disc is to be formed in a certain ratio to the bore diameter. It is stated that the width dimension of such perforated disks should be in the range from 0.125 to 0.25 times the bore diameter.
  • the solutions according to DE 38 21 930 and 43 38 347 address the problem of the material design of perforated disks taking into account the mechanical processing and the pairing with the respective knife.
  • DE 38 21 930 describes a meat grinder, the perforated disc and knives of which are provided with a ceramic cover layer.
  • Aluminum oxide (Al 2 O 3 ), zirconium oxide (ZO 2 ), silicon carbide (SiC) or mixtures of these materials are used as ceramic materials.
  • DE 43 38 347 presents a perforated disk for cutting sets of a meat grinder, which is characterized in that this perforated disk is made from a gray cast iron, preferably from a spheroidal graphite cast iron or from a laminar gray cast iron and their degrees of hardness are in the range of 25 to 28 HRC.
  • a perforated disc-knife combination for cutting sets of meat grinders to develop their costs and technical effort the production of perforated disks is significantly reduced, at the same time the residence time of the wolf material within the through holes of the perforated discs and the The ability of the wolf material to bind through cross-sectional displacement or cross-sectional changes should be increased, at the same time with the respective executing cut through the respective Knife blades a uniform meat particle size can be achieved.
  • the perforated disks are of this type trained that their through holes are not smooth holes, but these Through holes are designed in a stepped form or with appropriate approaches Mistake.
  • these approaches and narrowing or transitions what is to be conveyed becomes Well kept and rolled, turned and finally by the material to be conveyed after repeated mixing, conveyed out of the respective through hole and has a structure after leaving the end perforated disc of a cutting set has high cohesion and thus realizes good water absorption of the wolf material becomes.
  • blades used with differently arranged and trained cutter bars or cutter blades are designed both as a continuous Knife bar, from the outer ring of the knife to the hub of the knife, as well as hanging Blade, directed from the outer ring of the knife to the center of the hub and as a standing blade, from the knife hub facing the outer ring of the knife.
  • the arrangement of these knife bars / knife blades is chosen so that the spaces between 2 or 3 knife bars / knife blades are of the same size in relation to the surface of the respective perforated disk and thus form equally large cutting zones. This results in equally large distances a, which document the distances from cutting blade to cutting blade.
  • This knife shape determines the particle size as a temporal effect on the raw materials that have penetrated into the holes in the perforated disc.
  • the formation and arrangement of the holes in the perforated disc body and the formation of the knives, as well as the pairing of knives and perforated disks, require a certain effective relationship and ensure effective distances between the knife bars / knife blades and a certain number of holes in the perforated disks that are in the effective area of the respective knife bar / knife blade lie. In this way, the same distances between the individual knife blades and the through holes of the perforated disks as well as the same number of holes in the individual cutting zones are achieved, at the same time the same particle sizes of the wolf material are achieved and corresponding homogeneous machining conditions due to the effects within the holes of the perforated disks.
  • the through bores of the perforated disks can have different cross-sectional shapes in a known manner, but which are introduced into the respective perforated disk body in such a way that the number and spacing of the through bores is always the same in the individual cutting zones.
  • the through holes can have circular but also differently shaped cross-sectional shapes, for example square cross-sectional shapes or polygonal cross-sectional shapes.
  • the essential feature of the new solution is that the through holes of the perforated disks are not straight, but are stepped with different cross-sectional area sizes and are zone-like with the same number of holes in a defined distance range from the cutter bars / cutter blades.
  • the through bores can be formed with one and more shoulders or constrictions, which narrow towards the outlet side or also in the combination of large cross-section, small cross-section, large cross-section.
  • the perforated disks 1 designed according to the invention correspond to the known perforated disks in terms of their outer shape and basic structure and consist of a perforated disk body 2, which is designed with a central bore 3, via which the individual perforated disks 1 are accommodated on the axle drive pin, but no closer shown screw conveyor, while the knives consist of different types of spacing blade systems.
  • the end faces 9; 10 of the perforated disks 1 are designed as parallel surfaces, the end face 9 being aligned with the raw material flow direction 8 and representing the knife running side of the respective perforated disk 1, while the other end face 10 forms the raw material exit side.
  • the through bores 4 of the perforated disks 1 are formed axially parallel to the central axis of the respective perforated disk 1 in the perforated disk body 2.
  • 5, 6 form zone-like knife spacing systems, so-called cutting zones 16, which ensure that particles of the same size are formed.
  • the through bores 4 are of stepped design in such a way that the diameters of the inlet bores 5 and the outlet bores 7 have different dimensions and in the transition region from the inlet bore 5 to the outlet bore 7 there is a function-related division of the raw material Flow is achieved, thus the dwell zones 11 and massage zones 12 according to the invention result, while the particle sizes within the cutting zones 16 are determined and thus lead to uniformly processed meat particles.
  • the functional relationship between the inlet bores 5 and the outlet bores 7 acting as a massage bore and the knife bar system, cutting zones 16, is directly determined by the geometric dimensions of the through bores 4, which are divided into inlet bores 5, center bores 6 and outlet bores 7. It is essential that The length ranges of the respective dwell zones 11 and massage zones 12 are derived from the individual diameter specifications.
  • the dwell zone 11 of the perforated disk 1 shown in FIG. 1 is formed with a length dimension of 3 to 4 x the diameter dimension of the inlet bore 5 and the total width dimension of the perforated disk 1 is determined according to the ratio 5 to 6 x D1 + D2 / 2
  • the perforated disk 1 shown in the illustration according to FIG. 2 is a perforated disk 1 of multiple stepped design, which in the broadest sense can also be referred to as a massage perforated disk.
  • a perforated disk 1 of multiple stepped design which in the broadest sense can also be referred to as a massage perforated disk.
  • through bores 4 are formed with a plurality of transition points.
  • these through bores 4 are formed in three different diameter ranges, which result in the inlet bore 5, the central bore 6 and the outlet bore 7.
  • the dwell zone 11 results directly in the length region of the central bore 7, which results in value from the relationship 1 to 2 ⁇ D 2 to the diameter of the central bore 6.
  • the direct diameter ratio of the inlet bores 5 to the outlet bores 7 lies in the range 0.5 to 0.95, while the dwell zones refer to the same bore diameter the inlet bores 5 and the outlet bores 7, with lengths in the range from 1 to 2 or, depending on the desired frequency of the mixing to be carried out and Massage of the raw material, in the range 3 to 4 x corresponding to the respective bore diameter of the inlet or outlet bores 5, 7, are formed.
  • FIGS. 3 and 4 Further explanations regarding the introduction and arrangement of the through bores 4 in perforated disks 1 are shown in FIGS. 3 and 4.
  • the diameter of the inlet bores 5 and outlet bores 7 is the same; the immediate function-related subdivision of the dwell zone 11 and the massage zone 12 is achieved by an extension 13 between these two bores 5; 7 scored. This is done in such a way that the axes of the inlet bores 5 and the outlet bores 7 are offset parallel to one another.
  • both the inlet bores 5 and the outlet bores have 7 the same diameter, and the transition point between these two Boreholes is designed and constructed as a dwell zone 11 by being between the inlet boreholes 5 and the outlet bores 7 each have a transition bore 14 with a smaller one Diameter is provided.
  • An advantageous use of the inventive perforated disks 1 consists in one Paired arrangement of perforated disks designed in this way 1. Which means that on the drive pin a screw conveyor one or more perforated disks 1 arranged side by side be, whereby a change in the residence times of the raw material to be comminuted within the dwell zones 11 and massage zones 12 is reached.
