Definitions

  • the present invention relates to an automatic installation for slicing and calibrating cheeses, and it relates more precisely to such an installation for slicing and calibrating cheeses produced in millstones, in particular emmental.
  • the cheese wheels have so far been cut manually, using a device called a slicer, by first cutting each wheel in a direction substantially perpendicular to a certain diameter of the wheel, in successive and substantially parallel slices, the first and last of which, consisting essentially of crust, are called the heels, and the others of which are called the loins.
  • the two heels, the removal operation of which is called offset, are generally not of equal thickness.
  • each loin is taken up manually for the cutting of the two falls visually, constituted not only by the pieces of crusts, at the two ends of the loin, but also by the pieces of cheese located outside the maximum parallelepiped volume of cheese that 'it is possible to cut in each lanyard.
  • each lanyard free of its two scraps, is cut into plates, which can then be individually conditioned, for example by an automatic weighing, packaging and labeling chain.
