Definitions

  • the invention relates to a food processing machine in which an electrical voltage potential is present between the food and parts of the food processing machine.
  • Food processing machines are well known from the prior art. These machines are used to comminute, mix, shape and / or arrange foods, in particular meat and cheese, in a certain configuration.
  • the food processing machines are so-called cutters, which have a bowl driven about the vertical axis.
  • the bowl essentially has the shape of a tom, a motor-driven knife shaft is provided approximately tangentially to the torus axis, which carries a knife head equipped with knives, which shred the food in the cutter bowl.
  • the present invention was therefore based on the object of providing a food processing machine which does not have the problems of the prior art.
  • the object of the present invention was to reduce the deposits of food, in particular protein deposits, on machine parts and to minimize the force during cutting.
  • the object is achieved with a
  • Food processing machine in particular a cutter, in which an electrical voltage potential is present between the food and at least part of the food processing machine. It was extremely surprising for the person skilled in the art and it was not to be expected that the food processing machine according to the invention would succeed in reducing the buildup of food on the food processing machine and the force for processing or processing food. The cleaning effort of the food processing machine according to the invention is reduced and the hygiene is improved. The cutter's knives need to be ground less frequently.
  • Food in the sense of the invention means every food in every form.
  • Preferred foods are meat or cheese products and confectionery, in particular chocolate or muesli bars.
  • Preferred manifestations are, if appropriate, frozen food blocks, which are processed into sausage meat, for example, in the cutter.
  • the propensity for adhesion of the food to the housing or other machine parts, such as, for example, the knife or the knife head is reduced by the proposal according to the invention.
  • a food processing machine in the sense of the invention is any machine familiar to a person skilled in the art, with which food is comminuted, mixed, shaped, arranged and / or conveyed. According to the invention, an electrical voltage potential is applied between the food and parts of the food processing machine.
  • the food processing machine is preferably a so-called "cutter", with which food is comminuted and, if necessary, emulsified.
  • the cutter With the cutter, an electrical voltage potential is applied between the food and the cutting knife.
  • this embodiment of the present invention not only is the hygiene increased, but also the cutting force is reduced. The service life of the knives is also positively influenced.
  • the food processing machine is also preferably a wolf, in particular a meat grinder, with a wolf housing and one in it arranged conveyor for the transport of the material to be fed via a cutting device to a conveying opening, the cutting device preferably having a perforated disk and a cutting knife which can be rotated in front of the perforated disk in the conveying direction.
  • the cutting knife is preferably electrically insulated from the other parts of the food processing machine and a corresponding voltage potential is impressed on the knife via corresponding sliding contacts or the like.
  • the food is at positive or negative voltage potential with respect to at least a part of the food processing machine, preferably the cutting knife.
  • the electrical voltage potential can be impressed into the food by any means which is electrically conductive and which is in sufficient electrical contact with the food.
  • the food is preferably in an electrically conductive support, for example the bowl of a cutter, which is at a corresponding potential.
  • the corresponding voltage potential is then impressed into the food via the support.
  • the polarity of the food is also preferably carried out via sensors and / or wipers with which the food is guided and / or moved in the food processing machine.
  • the lowest possible tension is preferably applied between the machine part and the food in order to avoid damage to the operating personnel and / or the product to be processed.
  • the tension must be so great that a reduction in the deposits of food on the respective parts of the food processing machine, in particular the knives and the bowl of the cutter, is reduced.
  • the voltage is particularly preferably ⁇ 60 V, very particularly preferably ⁇ 30 V.
  • the voltage potential is preferably not maintained permanently but only intermittently. The voltage potential must be high, particularly during a product change or maintenance or adjustment work on the machine be set to zero.
  • Another object of the present invention is a method for processing food in a food processing machine, in which an electrical potential is applied between the food and the food processing machine before processing the food.
  • the food processing machine is preferably a machine with which food, in particular meat, is comminuted and / or emulsified. Such machines are called cutter or wolf.
  • the method according to the invention is simple and inexpensive to carry out.
  • the contamination of the knife for example due to protein deposits, can be significantly reduced.
  • the cutting forces required are far lower than in cutting processes according to the prior art.
  • the food processing tools, especially the cutting knives, which are made of high-strength steel, are less susceptible to corrosion and the knives stay sharp longer.
  • the contamination of the containers, for example the cutter bowls in which the food is stored, can also be reduced.
  • Another object of the present invention is therefore the use of an electrical voltage potential which is present between the knife of a food processing machine and the food to be cut and / or emulsified to avoid corrosion.
  • the food is preferably at a positive voltage potential in relation to the cutting knife (s), particularly preferably the cutting knife (s) of a cutter or wolf.
  • the present invention furthermore relates to the use of an electrical voltage potential which is present between the knife (s) of a food processing machine, particularly preferably a cutter or grinder, and the food to be cut and / or emulsified, to improve and / or maintain the cutting ability of the knife.
  • Another object of the present invention is the use of an electrical voltage potential which is present between the container in which the food is located, for example the cutter bowl, and the food to be cut and / or emulsified, in order to reduce contamination
  • FIG. 1 shows a cutter according to the invention
  • Figure 2 shows a wolf according to the invention
  • FIG. 1 shows an embodiment of a cutter 2 according to the invention.
  • the product to be comminuted and / or emulsified lies in the bowl 5.
  • the product, meat is comminuted and / or emulsified by the cutting knives 1.
  • the cutting knives 1 are set to negative potential, the bowl 5 to positive potential. This is indicated by the poles marked with - and +. Since the bowl 5 is electrically conductive, the meat is also placed at a corresponding +/- potential.
  • Figure 2 shows parts of the working area of a wolf.
  • a screw conveyor 21 is arranged, which conveys the material to be cut in the direction of arrow 8 and which has a drive shaft 22, which Knife 1 drives .
  • the cutting device 23 also has two perforated disks 25 which cooperate with the knife 1 and a bearing ring 15.
  • the cutting knives 1 are set to negative potential, the wolf housing 20 to positive potential. Since the wolf housing 20 is electrically conductive, the meat is also placed at a corresponding +/- potential.
