Definitions

  • the present invention refers to the field of processing a food substance which presents itself in the shape of a more or less continuous mass to be ground, and more specifically it regards a complex or unit to be mounted on a machine for supplying pieces of meat which form a more or less continuous mass and which are supplied by an auger arranged upstream of the unit according to the present invention.
  • the continuous mass of food substance could be the meat (for example pork meat) for producing sausage (e.g. mortadella).
  • a finisher/rougher could be used in order to render the meat more uniform before it reaches the grinding and mincing unit according to the present invention.
  • Such treatment of the meat is carried out in processing lines installed in sterile environments at controlled temperature (usually about 16 degrees centigrade).
  • the pieces of meat (having a temperature of about -4°C) pass through units which progressively reduce the size thereof, mincing them and forming an increasingly uniform mass; in particular, said pieces of meat first cross through finishers before then reaching a final unit, like that which is the subject of the present invention.
  • Such unit can be of various types.
  • a pack of perforated and stationary circular discs is used; these are alternated in the unit itself with radial knives which, by scraping the surface of the perforated discs, produce a guillotine-cutting effect on the meat (pushed by suitable means such as an auger or the like).
  • the meat, or another food substance to be minced is chopped into increasingly smaller particles in accordance with the decreasing size of the holes present in the various perforated circular discs of the processing unit.
  • the grinding unit has considerable and non-constant load loss (gradient) through the discs, especially by virtue of the fact that the discs with small holes have an overall surface of the holes (total area for the passage of the food substance) clearly lower than that of the discs with holes of larger diameter (even if the holes are less numerous); hence, given that the diameter of the flat circular discs is substantially identical for all the discs, the force necessary to make the meat pass through the discs is not the same, but rather it tends to increase towards the outlet of the grinding unit, and from this it is clear that more power is absorbed for working the meat;
  • the grinding unit could be made more compact; this is important since it preferably constitutes a "module" to be mounted on the outlet of the machine of the meat processing line which comprises one or more loading hoppers, the supply channels, and the finishers, in addition to the augers which feed the meat itself towards the outlet (where the final grinding unit is situated); a more compact module would be easier to handle, transport, disassemble and reassemble, at the end of the daily production, for preserving it in a refrigerator at low temperature, so as to prevent the necessary operations of disassembly of the single components and cleaning adapted to prevent bacteria proliferation in the residual meat that remains attached; this would in fact be inadmissible, since during the subsequent work shift the bacteria would be mixed with the produced fresh meat;
  • Object of the present invention is the introduction of particular knives (elements with blade) that allow remedying the problems of the micro-welds, without however giving up the advantages brought by the new technology of the patent US 7,389,954 Bl, i.e. a greater compactness of the grinding unit, a greater energy efficiency (ratio between the product quantity and the absorbed energy), and a uniform distribution of the load (and hence already a reduction of the incidence of failures and problems of the production line).
  • FIGURE 1 is half axial section C-C (see Fig. 3) of the grinding unit with cylindrical form of the present invention
  • FIGURE 2 shows, in a very schematic manner, the inventive concept that underlies the present invention
  • FIGURE 3 is a side view of the grinding unit with cylindrical form of the present invention
  • FIGURES 4A and 4B are cross sections A-A and B-B, respectively, executed in different axial positions and referred to the embodiment of Fig. 3 of the machine of the present invention
  • FIGURE 5 shows a second grinding unit (now conical) according to the present invention, flanged and flange-coupled to a tubular part of the machine for supplying the meat (already finished) or another food substance to be chopped;
  • FIGURES 6A, 6B and 6C are cross section views in the planes B-B, C-C and D-D of Fig. 5, executed in various axial positions of the conical grinding unit according to the second embodiment of the invention;
  • FIGURE 7 is a partial side view, partial sectional view, and with tears, in order to see the various annular perforated elements of the stationary sieving means (with holes of progressively decreasing diameter); it is observed that the knives were not drawn in this figure 7 in order to simplify the drawing. Detailed description of the invention
  • the unit 100 of the present invention in this particular embodiment, comprises a substantially cylindrical and stationary external jacket 1, bearing on its internal surface a plurality of convex annular recesses 2, separated from each other by annular ribs 3, the number of such annular recesses 2 and such annular ribs 3 of the external jacket 1 being variable according to the circumstances, i.e. according to the requested processing stages (nature of the food substance, etc.).
  • the annular recesses 2 do not form sharp edges, i.e. they have a curvature that varies gently without singularities, in a manner so as to facilitate the passage of the food substance that crosses through the space defined by such recesses 2.
  • a rotary thrust and cutting body 4 Inserted in the jacket 1 is a rotary thrust and cutting body 4 which could also be composed of single elements 4a, 4b, 4c, 4d, etc., integrally connected to each other in order to be able to rotate simultaneously together with respective blades 6a, 6b, 6c, 6d, etc., which are rigidly connected to the rotary thrust body.
  • the rotary thrust and cutting body 4 rotates around the geometric axis "X-X", see Fig. 3, during the operation of the unit, while a cylindrical stationary sieving means 7 is extended along the entire external jacket 1 and is fixed inside the latter (preferably in a removable manner), and in any case is stationary.
  • the sieving element 7 is directly in contact with the annular ribs 3 at the respective points visible in Fig. 1.
  • the sieving element 7 constitutes a tubular body, i.e. cylindrical, e.g. made of food-grade steel like substantially the entire unit 100, subject of the present invention.
  • the section C-C of Fig. 1 of course constitutes only half of the section executed in the homonymous plane of Fig. 3; in other words, it must be intended duplicated/mirrored symmetrically under the axis X-X of Fig. 1.
  • various circular collar area zones 8 are provided, separated from each other by slots 10, each circular collar area 8 having a plurality of tilted holes 9 for facilitating the passage of the meat.
  • various slots 10 are equally distributed in a circle on the sieving element 7, all around the rotary thrust and cutting body 4.
  • various curved blades 6a (or 6b, or 6c, or 6d) are arranged all around the rotary thrust body 4 and are integral therewith within annular grooves or cavities 11, in the respective axial position of the mincing unit 100. This is inferred, for example, from figures 4A and 4B, in cross section, in which for the sake of simplicity only some of the blades 6a (or 6b) have been expressly indicated by their numeric reference numbers 6a (or 6b).
  • the meat (or generally a food substance to be minced) crosses the grinding unit 100 from right to left (in Fig. 1), following a zigzag path, specifically:
  • the tilt of the holes 9 is such to facilitate the passage of the meat under the thrust of the auger of the machine placed upstream (not shown) and the blades (suitably shaped) of the rotary thrust and cutting body 4.
  • the auger could also not be integral with the rotary thrust body 4; in this case, the two components could independently rotate and their speed could be independently controlled.
  • the element 12 of Fig. 3 could serve as a rotation shaft (moved by autonomous motor) of the rotary thrust and cutting body 4, which would then be decoupled from the auger (not shown) for supplying the food substance.
  • the food substance is drawn from an outlet of the unit 100, for example from the radial opening indicated with 13 in Fig. 1.
  • a generic curved blade "6i" arranged in a generic annular cavity 11 has a longitudinal incision 14.
  • Such longitudinal incision 14 is extended in the extension direction of the blade 6i, which - as always - is extended between two respective ribs 3' of the rotary thrust body 4; in the drawing, only one blade portion 6i and a part of the incision 14 are shown, the dashed lines 15 and 16 indicating that the blade 6i is in reality extended from one end of the annular groove 11 to the other.
  • the incision 14 "removes" a certain distance/measure from the normal thickness of the blade 6i, and hence the blade 6i becomes elastically yieldable.
  • the upper edge 17 of the blade 6i is in sliding contact with the respective circular collar area 8 (not shown in Fig. 2) bearing the tilted holes 9 for the passage of the food substance.
  • a material such as silicone or the like fills the longitudinal incision 14 in a manner so as to prevent deposits (crusts) of food substance, which over time would nullify the elastic pliability effect of the blade 6i due to the longitudinal incision 14.
  • all the blades 6a, 6b, 6c, 6d are elastically yieldable.
  • the present invention is not limited to the specific embodiment of Fig. 2 but rather is extended to any type of blade 6 equipped with means that render it elastically yieldable to the possible convexities of the stationary sieving means 7, thus limiting the rubbing (and the consequent micro-welding of the metal) between these components 6 and 7 in relative rotation.
  • the final tubular part 18 of the machine for supplying the food substance is couplable, by means of a flange 19b, to the flange 19a of the frustoconical unit 100' of the second embodiment of the present invention.
  • the shaft 12 as usual constitutes a rotation and centering member for the rotary thrust and cutting body 4 inside the external jacket 1.
  • the diameters of the sieving holes 9 are progressively decreasing in the direction of the arrow F (direction of passage of the meat or the like), from one collar area 8 to the next.
  • the slots 10 ensure a practically rectilinear (axial) passage of the food substance among the various mincing stages, thus reducing the force employed and thus the power (increase of efficiency);
