Definitions

  • the invention relates to a machine for cutting food, in particular of vegetables, in strips with a drum rotatable in a machine frame, whose shell has at least one opening through which inside the Drum located and rotatable with this cutting material due to the centrifugal force emerges radially outward, wherein of the material to be cut by means of a with the Machine frame connected knife discs are cut off by means of a circular meter set, a plurality of rotatably drivable on a common shaft arranged, disc-shaped circular knives, in strips are cut.
  • Such machines are known for example from US-A-2,541,180 and are used in particular for cutting potatoes, carrots, celery, radishes, onions and other vegetables, but also for cutting frozen meat, used.
  • the drum acts as Centrifuge, on whose jacket inside a plurality of extending in the axial direction Mit supportiverippen are arranged, which ensure that in the drum located cutting material of the rotation of the drum follows without slip. Furthermore
  • the driving ribs take on the task of cutting the discs to exert the necessary counterforce on the material to be cut.
  • the crop feed is usually via a hopper, of which the cut material is directed to a central opening in an end face of the drum.
  • the opposite Front side of the drum whose axis of rotation is usually horizontal runs, is closed, so that the material to be cut with rotating drum can only escape through the openings in the drum shell.
  • a disadvantage of the known machines is that particularly sensitive Products to be cut when passing through the circular knife set of a large pressure load are exposed. This is due to the fact that in the cut slices invading circular blades inevitably cause a Schneidgutverdrfitung which entails a compression of the material to be cut. Especially with pressure sensitive and juicy cuttings such as onions therefore to an undesirably large juicing, as a clear lack of quality the cut strip or cube is to be regarded. Aspirations, the pressure load By reducing the thickness of the circular blades are reduced by a not to be fallen below minimum material strength set very narrow limits.
  • the invention has for its object to provide a cutting machine, with the sensitive and juicy cuttings without quality reduction in stripes or cubes are cuttable.
  • this task solved in that in the conveying direction of the cut slices at least two circular knife sets are arranged one behind the other, whose waves parallel to each other, wherein the circular blade of the second circular meter set perpendicular to the conveying direction to the circular knives of the first circular knife set are arranged offset.
  • the pressure load of the material to be cut for example when using two circular knife sets arranged one behind the other halved, since in each of the two stages connected in series, only the Half of the total on both knife sets existing circular knife with the Product are engaged. In this way, the juice loss can help in this regard sensitive Schneidgütem be significantly reduced.
  • the circular knives of the first circular knife set themselves in the spaces between extend the circular knives of the second circular knife set, wherein the distance the axes of rotation is approximately dimensioned so that in a plane parallel to The circle knives projected outlines of the circular knives of the two circular knife sets in a tangential plane to the outer surfaces of the two waves cutting the circle knife sets.
  • a development of the invention finally consists in that in the field of Kreismesser with a slotted plate is provided, which the conveyor cross section to the Rotary axes of the Kreismesser with limited and of the circular knives of Circular knife sets in slots adapted in their length and width to the circular blade are, are penetrated. In this way, an unwanted intrusion of cutting material in areas between the waves of the KreismesserA prevented and thus a continuous product management can be achieved.
  • the machine 1 shown in Fig. 1 for cutting in particular vegetables in Cube has a drum 2 with horizontal axis of rotation, which via a funnel 3, in an unillustrated opening within an end face of the drum. 2 opens, can be equipped with items to be cut.
  • the radially due to the centrifugal force Breakthroughs in the drum 2 protruding material to be cut with the help of a firm sliced with a machine frame connected knife.
  • These Slices are then using two Kreismesser algorithms 4 and 5, whose Rotary axes parallel to the axis of rotation of the drum 2, cut into strips. Subsequently, these strips with the help of a due to a cover 6 not visible hack roll cut into cubes.
  • the cuttings leave the machine 1 through the outlet cross section of an ejection shaft formed by the cover 6.
  • a hacking roll 10 with five circumferentially distributed and parallel arranged to each other cutter bar 11, with the rear edge 12 of the Knife 9 cooperate in the form of a counter-blade.
  • the speed of the chopping roll 10 are the emerging from the second circular knife set 5 Strip into cubes or cubes parts.
  • a cylinder 13 surrounding the drum 2 is shown in FIG an exit region 14, in the direction of rotation (arrow 15) of the drum 2 the fixed Knife 9 is upstream, spirally widened. This is done after a controlled passage of the material to be cut through the respective breakthrough in the drum 2 cutting a disk of thickness 16. Due to the centrifugal force the material to be cut always lies in the outlet area on the inner wall 17 of the cylinder 13, which increasingly moves away from the axis of rotation of the drum 2. With help an adjustment 18, the thickness 16 of the discs can be varied.
  • the cut slices then pass through two circular knife sets 4 and 5, the axes of rotation parallel to each other and to the axis of rotation of the drum. 2 are aligned.
  • Each circular knife set 4, 5 has a plurality of parallel to each other arranged, disc-shaped circular knives 19 and 20.
  • the conveyor cross section of the strips is directed towards the axes of rotation of the circular knife sets 4 and 5 bounded by a slot plate 22, in the slots of the Circle knives 19 and 20 penetrate.
  • the slotted plate 22 prevents the cut Strip due to friction on the flanks of the circular blades 19 and 20 of the knife 19 lifted and on a circular path in areas between the waves of the Kreismesser accounts 4, 5 and behind the shaft of the second Circular meter set 5 moves.
  • the circular blades 19 extend of the first circular knife set 4 in the spaces between the circular knives 20 of the second circular meter set 5 or vice versa. Due to this overlap of Circular knives 19 and 20 in one of the axes of rotation of the Kreismesser accounts 4 and 5 connecting Level is achieved that the cut material after leaving the Circular knife set 4 enters directly into the circular knife set 5.
  • the Kreismesser algorithms 4 and 5 is arranged offset, is within the winningquer cut except for the area of the gusset 23 no overlap of the circular blade 19 and 20 present, so that essentially either only the circular blade 19 of the first circular knife set 4 or the circular knives 20 of the second Circular meter set 5 are in engagement with the discs to be divided.
  • the Pressure load of the crop is due to the displacement either only by the circular knives 19 or only by the circular knives 20 in comparison to Machines with a single circular knife set, which is twice the number of circular knives thereby approximately halved.
  • the strips are after leaving the second circular set of 5 using a about a parallel axis of rotation rotating Ralphwalze 24 into cubes.
  • Thehackwalze 24 has five over the circumference of a cross-sectionally star-shaped roller body Distributed 25 arranged balancing knife 26, which at a close distance the trailing edge 27 of the slot plate 22 pass and with its leading edge 28 after Passing through the conveyor cross section with the rear edge 29 of the knife 9 in Form a counter-knife interact.
  • a compressive load of the material to be cut does not take place by the Hackwalze, because of the large free length of Blade 26 in conjunction with the height of the ribs 30 of the roller body 25th there is enough room to drop the dice.
