Definitions

  • the invention relates to a device for cutting food with ultrasound and ultrasonically excited cutting tools, in particular for cutting dough and bakery products, also suitable for cutting, for example, cheese, fish, fruit slices and similar products.
  • WO 94/22645 which is formed with a knife, which is excited by a piezoelectric vibrator and a knife is used, which is formed as an elongated blade which is bent at one end almost at right angles and the bending radius of this bend and the blade material to the frequency of the piezoelectric vibrator is adjusted.
  • This cutting tool is excited by an ultrasonic generator and additionally set in rotation, so that here a combined cutting tool is presented, which, in order to achieve required cutting qualities, on the one hand ultrasound excited, but in addition requires a rotary motion to meet the required qualitative requirements ,
  • food cutting machines of the type mentioned are formed with means which, taking into account the respective cutting processes to be realized, are arranged in the corresponding cutting machine in such a way that they are carriers of the respective cutting tools and ensure the positioning of the cutting tools for the food product to be cut , regardless of whether cutting operations in the longitudinal or transverse direction to be cut product to be performed.
  • the invention also includes that the geometric shapes of the ultrasonically excited cutting tools are adapted to the material to be cut and, analogously, the assignment of the ultrasonic transducer to the sonotrode, which is connected to the cutting tool.
  • the cutting tools are adapted in shape to the respective cutting task and arranged on the device in the technological process of the cutting machine, this taking into account the supply of the material to be cut, the cutting modules, securing the position of the required sound and safety elements and the removal of the material to be cut from the machine including the parameter control.
  • the advantageous cutting effects of this solution presented arise from the supply of the material to be cut in the device rigidly arranged cutting tool, which is formed with a geometry matched to the product and excited in a known manner with ultrasound and vibrating between 18 to 30 kHz is offset.
  • the Figures 1 and 2 show knife shapes for ultrasonically excited cutting tools 1, which are circular, in circle segment shape, as a circular arc, similar boomerang-shaped and elongated surface part, which are provided at the respectively marked with a cross point, the receiving point 11, with ultrasonic transducers 6 with sonotrode, the excite the cutting tools 1.
  • cutting tools 1 are excited perpendicular to the surface of the respective cutting tool 1.
  • Cutting tools 1, formed as a spade blade or longitudinal blade are in the FIG. 2 shown, the respective US transducer 6 with sonotrode is attached to the receiving point 11 of the cutting tools 1 shown and the excitation of the cutting tools 1 takes place along its surface, as indicated by the arrow directions.
  • the designs of the ultrasound-excited cutting tools 1 are not limited to the illustrated geometric illustrations, but are adaptable to the respective technological cutting process.
  • FIGS. 3 to 11 illustrated embodiments show the arrangement of ultrasonically excited cutting tools 1 to cutters 2, which are arranged in the respective cutting machine and it is shown how the cutting devices 2 shown in principle are positioned with the arranged ultrasonically excited cutting tools 1 to 8 cutting material or can be positioned.
  • FIG. 3 shows the arrangement of an ultrasound excited cutting tool 1, which is clamped on one side and fixed in the cutting device 2, wherein the cutting device 2 itself is pivotally adjustable to the turntable 3, on which the cutting material 8 to be cut, for example, a cake bottom, rests.
  • the arrows 5, 4 on the one hand, the pivoting direction of the cutting device 2 and on the other hand the direction of rotation / mobility of the turntable 3 are documented.
  • FIGS. 4 a and 4 b show how the other subsequent embodiments also, a principle arrangement of cutting tools 1 to the cutting devices 2 and the assignment / arrangement to the respective cutting machine with the additional equipment, here a conveyor belt 7 with superimposed cutting material 8, and two cutting tools 1, here in the form of circular knives, which are rigidly mounted in the cutting devices 2, ie the circular knives are not rotatably mounted, but height adjustable in or with the cutting device 2 ( FIG. 4 a).
  • FIG. 4 b shows the top view of this cutter 2 and FIG. 5 It follows how the two cutting devices 2 are offset with the associated cutting tools 1 to each other to cut the material to be cut 8 also over the entire surface.
  • FIG. 6 Another embodiment is in the FIG. 6 shown.
  • the transport and cutting of the cut material 8 takes place on both sides of the cutting tool 1, which is also formed in this embodiment as a circular blade.
  • the cut material 8 is, for example, rolls that rest on the conveyor belt 7 in a parallel arrangement and are positioned by means of pressure and guide rollers or belts 12.
  • FIGS. 7 a and 7 b refer to a similar application example as in FIG. 6 illustrated and described, however, the cutting tool 1 is here designed as a sickle blade, an arcuate shaped knife similar to a boomerang, which is connected to a US transducer 6 with sonotrode and mounted in the cutting device 2.
  • the feed of the material to be cut 8 to the cutting tool 1 takes place in the arrow directions shown.
  • FIGS. 8 A and 8 b Another embodiment is in the FIGS. 8 A and 8 b shown, in which formed as a circular blade cutting tools 1 are used. These cutting tools 1 are not rotatably mounted in the device 2, however, arranged pivotally or movably.
  • the cutting tool 1 is linearly movable to the cutting material 8, characterized by the arrow directions.
  • the cutting material 8 rests on a support 9, which is formed with one or more grooves 10, in which protrudes the cutting tool 1 and thus the cut material 8 is cut or separated over the entire surface.
  • FIG. 8 b shows that the cutting device 2 is arranged with the inserted cutting tool 1 so that the cutting tool 1 with the cutting device 2 perpendicular to the cutting material 8 is movable, as documented by the arrow directions. From this representation also shows how the grooves 10 are formed in the support 9 for the cutting material 8 and also shows how the cutting device 2 is positioned with the cutting tool 1 each to 8 Schneidgut to quality cutting / cutting of the cut material. 8 to ensure.
  • a paired arrangement of cutting devices 2 with the associated cutting tools 1 is in the FIG. 9 shown.
  • the operation and operation of the cutting devices corresponds to the cutting device 2 according to FIG. 8 b.
  • the cutting tools 1 designed as blades are designed to a length of 300 mm, are clamped on one side in the associated cutting device 2 and are excited in their longitudinal direction by the respectively associated US converter 6.
  • FIG. 11 shows the use of a cutting tool 1 in the form of a spade blade, which is for example made of a very thin sheet, about 1 mm, and is fixed in the manner already described in the cutting device 2 and is excited via the provided US converter 6.
  • a cutting tool 1 in the form of a spade blade, which is for example made of a very thin sheet, about 1 mm, and is fixed in the manner already described in the cutting device 2 and is excited via the provided US converter 6.
  • Such formed cutting tools 1 are inexpensive to produce, their thickness-wise configuration has a positive effect on the cutting material 8, in particular by a very low displacement of the material in the immediate cutting process. Furthermore, it is advantageous that the presented cutting tools 1 are interchangeable, thus the effectiveness of cutting itself and the effectiveness of cutting machines are increased.
