Definitions

  • the present invention refers to the field of production of sausages, in particular of mortadella, and specifically it regards an improvement of the knife-holder rotors of the machines for producing sausages and more particularly mortadella.
  • the knives of a rotor must be arranged directly adjacent to the corresponding perforated disc, in order to be able to apply the desired pressure on the meat and push it (in addition to cutting it) against the respective perforated disc, so as to make it exit from the holes of the perforated disc.
  • Different units of this type are normally provided in the channel of the processing machine, i.e. various units comprising stationary perforated discs, as well as knife-holder rotors; for example, a pair of fixed perforated discs arranged in approached position encloses two knife-holder rotors arranged between said two fixed discs.
  • Another knife-holder rotor can be arranged more upstream in the channel, always directly adjacent to the perforated disc arranged more upstream.
  • the object of the present invention is to remedy the preceding drawbacks of the conventional machines for processing swine meat for producing mortadella.
  • FIG. 1 is a plan view of a meat processing unit, according to the present invention, observing the direction F2 opposite the flow Fl of meat to the interior of the channel of the processing machine (see Fig. 2);
  • FIG. 2 is the respective side cross section view (executed along the section line A- A of Fig. 1);
  • FIG. 3 is a view analogous to that of Fig. 2, but for a variant embodiment.
  • the machine, subject of the present invention can comprise various units (or sets) like that represented in these figures, within a meat supply and processing channel.
  • Figure 3 shows an improved variant that will be described hereinbelow.
  • a ring nut 1 is fixed in a rigid but removable manner (the details are not essential) to the wall of the supply and processing channel (not illustrated) of the machine (also not shown), Fl (Fig. 2) indicating the direction of the flow of material (meat).
  • the ring nut 1 rigidly supports two fixed perforated discs 2a and 2b, i.e. stationary with respect to the supply channel of the material, in which 2a indicates the "front” fixed perforated disc and 2b the “rear” fixed perforated disc, front/rear with respect to the arrow Fl .
  • a rotor with knives 3, of conventional type, is mounted "on the front part" with respect to the front disc 2a.
  • the motorized rotation shaft (not shown) of the machine is coaxial with the longitudinal geometric axis of the channel (axis of symmetry of the unit of Fig. 2) and is integral with the supply auger (also not illustrated) which makes the material advance in the channel by pushing it downstream with very high pressures.
  • the same rotation shaft in addition to rotating the conventional knife-holder rotor 3, to which it is connected, also rotates two knife-holder rotors 4a and 4b according to the present invention, in which 4a indicates the "front” knife-holder rotor of the invention, and 4b the “rear” knife-holder rotor of the invention (the terms front and rear always refer to the direction Fl of the material flow).
  • the abovementioned supply auger (not shown) is of course situated “above” the conventional rotor 3 in the drawing of Figure 2 and is connected thereto in a manner so as to rotate together therewith.
  • the knife-holder rotors 4a, 4b have different "spokes" or radial arms, respectively 5a and 5b, which meet at the central hub traversed by the rotation shaft (not shown); see Fig. 1.
  • the rotor 4a has - in this embodiment - four arms 5a, just like the rotor 4b has - in this embodiment - four arms 5b, said arms 5a and 5b alternating with each other and the two rotors of course being superimposed.
  • each radial arm (5a or 5b) of these innovative rotors 4a and 4b has a respective substantially rectangular recess for housing a corresponding knife, 6a or 6b.
  • each knife 6a or 6b is housed in a movable (rather than rigid) manner within the respective seat.
  • each knife 6a or 6b is mounted in the relative recess/seat in a manner so as to be able to rotate around a pin, respectively 7a or 7b, inserted transverse (perpendicular) to the radial direction of each spoke, respectively 5a or 5b. This is in particular inferred from figure 1 (double dashed lines).
  • the very high pressure of the meat mass over time generates a convexity in the central zone of the front perforated disc 2a and/or in the central zone of the rear perforated disc 2b, more exposed to the pressure peaks; the deformations can also partly occur in the components (spokes) of the rotors, and it is difficult to predict the exact behavior of these deformations.
  • the pins 7a and 7b are adapted to allow the oscillation of the respective knife 6a and 6b around them; such knife can thus follow the deformation of the corresponding fixed perforated disc, 2a and 2b.
  • each arm 5 a and/or 5b there could be more than one knife, for example two shorter knives arranged in a row, inserted in respective recesses with relative transverse pins 7a or 7b.
  • the length of the housing recesses is adapted (even if with suitable minimum clearances for allowing the rotation of the knife around the pin) to the length of the respective knife 6a or 6b; this is so in order to prevent small amounts of meat from entering into the recess, remaining embedded therein, since once hardened such meat could then be difficult to remove.
  • an elastic material could also be present on the bottom of a recess, in order to render the oscillation of the relative knife "soft" or springy.
  • the knives have a rectilinear blade that projects from the relative spoke, or radial arm, such blade could also have a slightly curved form.
  • the rotors are formed by a central hub and by four spokes, the number of spokes and/or their form or arrangement could vary according to needs. Also the arrangement of the spokes of one rotor with respect to the other could be different from that illustrated in the figures.
  • each processing unit has a structure like that shown; for example, also the conventional knife-holder rotor 3 (with knives rigidly fixed in the radial arms) could be substituted by a rotor with oscillating knives, according to the present invention, e.g. of the type of a rotor 4a or 4b.
  • a processing unit can be replaced if it has been excessively deformed.
  • Various processing units can follow each other along the supply and processing channel, with holes - of the perforated discs - with progressively decreasing diameter.
  • the two rotors 4a and 4b do not form a single body, but rather are simply superimposed, i.e. they are simply separately inserted on the rotation shaft (not represented) of the machine, by means of the non-circular hole of their central hub.
  • Figure 3 shows a variant with respect to figure 2, in which the hubs of the knife-holder rotors (which are indicated here with 4a' and 4b', respectively), are modified, having respective depressions - on the sides of the rotors that face each other - for receiving a helical spring.
  • helical spring 8 acts as a spacer for preventing the two rotors from adhering to each other due to the very high operating pressures.

Abstract

L'invention concerne une machine de traitement de la viande comportant, en aval de la trémie de chargement de viande, à l'intérieur du canal d'alimentation et de traitement de grandes pièces de viande froide (afin de les ramollir et de les rendre plus uniformes), des rotors porte-couteaux dont les couteaux (6a, 6b) sont montés rotatifs sur des goupilles (7a, 7b). Ainsi, les couteaux peuvent suivre – ou être adaptés à – la déformation des disques perforés (2a, 2b), empêchant le frottement et une usure excessive des matériaux qui composent les disques (2a, 2b) et les couteaux (6a, 6b).
