Definitions

  • the present invention relates to a rotating cutting knife which cuts a multiplicity of food slices from a food bar, the cutting knife being provided on a knife holder. Furthermore, the present invention relates to a slicing device having the cutting knife according to the invention and a method for slicing a food bar, in which a rotating cutting knife separates a plurality of food slices from a food bar, and a method for slicing a food bar, in which a rotating cutting knife, which is attached to a Knife holder is arranged, separates a plurality of food slices from a food bar and an interleaver is arranged between two food slices.
  • Such cutting knives, devices and methods are from the prior art, for example the DE 38 18 474 A1 and the U.S. 5,136,908 A , well known and are used to separate food slices from a food bar, for example a sausage, cheese or ham bar.
  • the food slices After being cut, the food slices usually fall a certain distance onto a support, for example a support table, and / or onto food slices that have already been cut. There they are configured into a portion and then transported away.
  • this falling movement and / or even when the respective food slice is cut off from the food bar leads to an undesirable deformation, for example folding or waviness, of the respective food slice.
  • the present invention relates to a rotary cutting knife which cuts a plurality of food slices from a food item.
  • a cutting knife can be, for example, a circular knife, a sickle knife or a spiral knife.
  • the knife is preferably a circular knife that moves on an orbital path and rotates several times around its own central axis when a slice of food is cut.
  • the knife is usually arranged on a knife holder that is part of a rotor of a slicing device. In such slicing devices, a bar of food is transported continuously or intermittently in the direction of the cutting knife along a feed route. This cutting knife separates food slices from the front end of the food bar.
  • the thickness of a food slice is determined by the feed rate by which the food bar is transported further while the cutting knife is not in cutting engagement with the food bar. After cutting, the food slices fall, in particular along a trajectory, onto a support table and / or onto an already cut food slice, where they are configured into a portion and then transported away.
  • the cutting knife is designed in such a way that a gas flow, in particular air flow, is generated which feeds each food slice during the cutting and / or afterwards, i.e. while it falls onto the storage table and / or onto food slices already present there, forms and stabilizes at least partially and / or temporarily in a desired shape.
  • the gas in particular air, flows along the already cut part of the food slice and / or along the completely cut food slice, which is preferably in flight, and shapes and stabilizes it.
  • a pulsating or continuous gas, in particular air, flow can be generated by the means.
  • the air flow can exert an impulse on the food slice and / or generate a negative pressure on one side of the food slice, as a result of which the food slice is shaped and stabilized in its desired shape.
  • the air flow can also be used to stabilize the cutting knife during its rotation so that it vibrates less, for example.
  • the gas flow, in particular air flow, generated by the means is used to apply an interleaver to each cut off slice of food.
  • An interleaver is a piece of paper or a paper-like substance that is placed between two slices of food to reduce their adhesion.
  • the means for generating the gas, in particular air, flow can be made of any material, it being preferably made of metal, in particular steel.
  • the means is a projection which is provided on the side of the cutting knife facing away from the food bar.
  • the means can be a sheet metal part that is attached to the writing knife, for example in a materially bonded manner, in particular by welding or gluing and / or non-positively and / or positively, for example by means of screws, rivets or the like becomes.
  • the cutting knife and the means are particularly preferably provided in one piece.
  • the means is preferably generated by a local accumulation of material or by reshaping the material from which the cutting knife is made.
  • the means is a bulge that is provided in the surface of the cutting knife.
  • Another object of the present invention is a slicing device on which the cutting knife according to the invention is arranged.
  • Another object of the present invention is a method for slicing one or more food bars, in which a rotating cutting knife, which is arranged on a knife holder, separates a plurality of food slices from one or more food bars, with an interleaver being arranged between two food slices which the interleaver is applied to a food slice by an air flow generated by a means arranged on the cutting knife and / or the knife holder.
  • At least one additional substance for example a disinfectant / cleaning agent or a replacement gas, is applied to the knife and / or product surface by means of the gas flow, in particular air flow (s).
  • the gas flow in particular air flow (s).
  • FIG. 1 shows an embodiment according to the invention of a slicing device.
  • the slicing device 5 has a knife 11 which cuts a food bar 2 into food slices 12.
  • each food bar 2 is transported continuously or intermittently in the direction of the cutting plane 6 of the knife 11 by a conveyor 4, here two conveyor belts 4.
  • the food slices generally fall onto a storage table 1 which is provided with transport means on which they are each configured to form a portion 14, here a stack.
  • These portions 14 are then transported away from the cutting knife area and then packaged.
  • the person skilled in the art recognizes that several food bars can be sliced at the same time. The slice thickness results from the feed distance of the food bar between two cuts.
  • the slicing device can have a gripper (not shown) for each advancing route, which gripper grips the rear end 13 of the food bar 2 before or during the slicing and stabilizes it during the slicing.
  • a means 3, here at least one projection is provided on the cutting knife, which corotates with the cutting knife 11 at the same speed and thereby generates a gas, in particular air flow, which stabilizes the at least partially, in particular completely cut off food slice in a desired shape and / or shapes.
  • the gas, in particular air flow preferably flows along the side of the food slice facing the food bar, in particular between the food slice and the cutting knife.
  • the gas, in particular air, flow can be pulsed and / or continuous.
  • Figure 2 shows a first embodiment of the cutting knife 11 according to the invention, here a circular knife.
  • This has a cutting edge 7 with which the food slice 12 is separated from the food bar 2.
  • the circular knife rotates both around its central axis 15 and around an orbital axis (not shown) during cutting, the speed of the cutting knife 11 around its central axis 15 preferably being a multiple of its speed around the orbital axis.
  • the cutting knife has a means 3 with which a gas, in particular air flow is generated during its rotation, in particular about its central axis 15. This preferably pulsed and / or continuous air flow forms and / or stabilizes each at least partially cut food slice, in particular during its flight onto the storage table.
  • the cut-off slice of food can, for example, be kept in a substantially planar shape by the air flow, which is advantageous, for example, for a stacked or shingled portion.
  • the gas in particular air
  • the means is a projection which is arranged on the side of the cutting knife facing away from the food bar.
  • the means 3 can be a sheet metal part which is fastened to the cutting knife 11, for example by welding, gluing and / or by means of screws, rivets or the like.
  • the means 3 is preferably in one piece with the cutting knife provided and can be made from the material of the cutting knife, for example by reshaping, for example a bulge or a material accumulation.
  • the one-piece embodiment of the cutting knife according to the invention has proven to be particularly hygienic.
