Definitions

  • the present invention relates to a process for cutting into portions circular products, in particular food products by the use of ultrasound, as well as to a vibrating sonotrode for the commissioning of such a process.
  • the invention proposes to provide improvements making it possible to remedy these drawbacks of the previous solutions.
  • the subject of this invention is a method for cutting portions into portions in circular food products such as cakes, cheeses and the like, characterized in that it consists in making a small diameter hole in the center of said circular product using a tubular sonotrode-knife, then cut into sectors using any suitable cutting element.
  • the invention also relates to a sonotrode-knife for implementing the method defined above, characterized in that it is tubular in shape, in that it vibrates at a frequency of the order of 10 to 40 kHz and in that it comprises means ensuring the ejection of the carrot cut from said product during the production of the central hole.
  • said tubular sonotrode has a cutting end having an internal draft angle.
  • the tubular sonotrode has a cutting end which has an external clearance angle.
  • the process which is the subject of the present invention for producing the central hole in the circular product which must then be cut into sectors comprises two operations: - the first made using the tubular sonotrode which is lowered by vibrating into the central part of the product in order to produce a substantially cylindrical central hole, the sonotrode then being reassembled by receiving an air jet to eject the cylindrical core thus cut and; - the second carried out using the same tubular sonotrode and under the same conditions as the first operation which makes it possible to obtain a perfectly cylindrical central hole.
  • the central plug or core is recovered to replace it in the bore immediately after the product has been cut into sectors so as to reconstitute the entirety of this product.
  • the method uses two vibrating sonotrodes: - A first tubular sonotrode with external clearance angle to make the central hole and obtain a perfectly cylindrical core and; - a second sonotrode whose clearance angle is inverted with respect to that of the first sonotrode and whose external diameter is slightly larger than the internal diameter of the first sonotrode to perfectly bore the hole previously made, the carrot then being replaced in place in the central hole thus reamed, immediately after cutting the product into sectors.
  • a sonotrode-knife 1 of tubular shape is used, the cutting end 1 ′ of which has an internal draft angle as can be clearly seen on the drawing.
  • this sonotrode vibrates in wavelength or in half wavelength depending on the thickness of the product at a frequency of the order of 10 to 40 kHz, and its outside diameter is slightly less than the diameter of the hole 5 provided. in holder 3.
  • the sonotrode 1 is then lowered into vibration in the product 2 ( Figure 2) and, during this operation the sonotrode 1 cuts a central hole 5 in the product by removing a volume (core 6) of material comparable to a plug.
  • the core 6 is ejected and the sonotrode 1 is withdrawn upwards, in its initial position.
  • the ejection of the core 6 is obtained by projection of a jet of compressed air blown into the hollow central part 7 of the sonotrode 1 by a supply line 8 opening into this central part.
  • the core 6 is ejected through the hole 4 of the support 3 as seen in FIG. 3.
  • a central hole 5 is produced in the product 2 having a very approximately cylindrical shape and constricted in the equatorial zone of the product.
  • this hole 10 has a diameter of the order of 10 to 30 mm in diameter.
  • This second example of implementation uses two tubular sonotrodes of different shape.
  • a vibrating sonotrode is used whose cutting end 11 ′ has an external clearance angle ⁇ .
  • the sonotrode vibrates down into the product 2 to make the hole 5 ′. It was then reassembled still vibrating and the insufflation of the compressed air jet ensures the expulsion of the carrot or plug 6 ′.
  • product 2 a cylindrical hole or housing 5 ′ whose dimensions and the surface condition does not allow the plug 6 ′ to be replaced in its place and place of origin.
  • This second horn 12 is used during the second step of the method, illustrated in FIG. 9 and which is identical to the operation described above with reference to FIGS. 4 and 5.
  • This second step makes it possible to ream the hole 5 ′ previously made so as to finally obtain a central hole 10 ′ which has a perfectly cylindrical shape and which not only makes it possible to cut the product into sectors under the conditions described above and also replace the carrot or plug 5 ′ in the central hole 10 ′. It is thus possible to reconstruct, after cutting the product 2 into sectors, the entire pre-cut shape of the latter, which thus retains its original presentation and its attractive appearance.
