Definitions

  • the present invention relates to meat processing apparatuses. Particularly the invention refers to a refrigerated meat grinder.
  • the known meat grinders essentially are provided with a feeding hopper for the meat to be minced, whose outlet engages the inlet manifold of a cylindrical body in which an helical screw pushes the meat against a rotating knife then through a bored disk that determines the meat calibration.
  • the screw is rotated by an electric motor by means of a gear mechanism for the motion transfer.
  • said meat grinders do not assure the good meat preservation and maintenance especially during the phase of processing pause; in fact the meat or its residues, which are in the not refrigerated portions of said known meat grinders, are subject to temperature increases that facilitate the bacterial proliferation.
  • a further drawback of the known meat grinders consists in the fact that they are bulky mainly because of the motor members and the motion transfer members to the screw and the rotating blades of the cylindrical body.
  • the main object of the present invention is to propose a totally hygienic and sure meat grinder, which guarantees the bacteriostatic effect of the low temperatures due to the refrigeration of the all grinder members, contacted by the meat.
  • a further object is to reduce the pouring of the meat liquids.
  • Other object is to propose a meat grinder having very small dimensions.
  • a further object of the present invention is to propose a meat grinder having a simple realization, low cost, high reliability and easy maintenance.
  • numeral 100 indicates the refrigerated meat grinder object of the present invention including a feeding hopper 2 of a mincing body 3 mechanically connected to the revolving speed reducer members 5 of the motor members 4.
  • the meat grinder 100 has furthermore cooling means 11. These latter include connected in a closed loop a refrigeration compressor 6; condenser means first 7 and second 8; evaporator means first 9 and second 10 respectively fit to cool the mincing body 3 and the hopper 2.
  • the connection between the elements of the cooling means 11 is made by means of refrigerating fluid ducts, not shown.
  • connection of the evaporator means 9, 10 is reversed in the closed loop path.
  • the hopper 2 and the mincing body 3 are insulated by insulating means 12 including a thermal insulating material whose portion is indicated with the numeral 18.
  • the mincing body 3 includes a feeding duct 25 for the passage of the meat to be minced and a back portion 26 and a front portion 27, with respect to the outlet 30 of the minced meat, which contain a helical screw and a rotating knife moved by means of a shaft connected to the outlet of the reducer members 5.
  • the reducer members 5 are constituted substantially by a worm reduction unit, connected to the shaft of the motor members 4 and pinion gear, connected to the shaft of the mincing body 3.
  • the shaft 29 of the motor members 4 is vertically positioned. It is important to notice that the vertical disposition of the motor members and the typology of the reducer members 5, allow to carry out an extremely compact meat grinder.
  • the first condenser means 7, connected whit the outlet of the compressor 6, include a coil contained in a tank 13 for the condensate of the evaporator means, first 9 and second 10.
  • the heat of the first condenser means 7 causes the evaporation of condensate water.
  • the second condenser means 8 consist of a finned coil cooled by an air flow blown by fans 14.
  • the first evaporator means 9 are constituted substantially by a coil helically wound around the feeding duct 25, and the portions back 26 and front 27, of the mincing means 3.
  • thermo-conductive paste 31 for instance of silicone-type.
  • the second evaporator means 10 includes a finned coil crossed by an airflow produced by second fans 15, for instance axial or tabential type. It is provided that the airflow can be inclined in comparison with the horizontal plane in order to generate a cooled air circulation that licks up the wall of the hopper 2 therefore causing the cooling of the meat contained therein.
  • the second evaporator means 10 consist of a shaped duct, for instance with loops, indicated with the numeral 19.
  • the shaped duct 19 expands on the lower surface of the hopper 2 and may extend to the side surface of this latter.
  • the shaped duct 19 adheres to the surface of the hopper 2 thanks to elastic means 16, for instance consisting of a layer of elastic synthetic material, fixed to a wall 17 which is positioned around the hopper 2 and has a thermal insulation 18.
  • the evaporator means first 9 and second 10 are carried out in a single body and are crossed by a airflow blown by the second fans 15 for the refrigeration of the hopper 2 and the mincing body 3.
  • the evaporator means first 9 and second 10 are coil shaped adherent to the mincing body 3 and to the hopper 2 supported by this latter by fixing means, for instance consisting of welded tabs.
  • the insulating means 12 consist of a thermal covering, for instance a spongy synthetic material in sheets or tape, adherently wrapped around the assembly composed by the second evaporator means 10, the hopper 2, the coil of the first evaporator means 9 and the mincing body 3 for thermally insulating these latter from the outside.
  • the operation of the meat grinder 100 is the same in all the described embodiments and provides the activation of the cooling means 11, the insertion of meat to be minced into the hopper and the activation of the motor members 4.
  • the meat while remaining into the hopper 2 and crossing the mincing body 3, is kept cooled by virtue of the cooling means 11.
  • the action of the helical screw and the rotating blades of the body 3, causes the expulsion of the minced meat.
  • the main advantage of the present invention is to provide a meat grinder whose members crossed by the meat are completely refrigerated and therefore have a sure and hygienic operation.
  • a further provided advantage is the reduction of the pouring of the meat liquids.
  • Further advantage of the present invention is to provide a reliable meat grinder, having an easy installation and maintenance, and low cost.
