Definitions

  • the invention relates to a machine for cutting food, in particular of vegetables, in strips with a drum rotating in a machine frame, whose jacket has at least one opening through which the inside of the Drum material to be sliced and rotatable with it due to the centrifugal force radially emerges to the outside, with the material to be cut by means of a Machine frame connected knife disks can be cut by means of of a circular knife set, which drives a plurality of rotatably on a common shaft arranged, disc-shaped circular knives, in strips are cuttable.
  • Such machines are generally known and are used in particular for cutting of potatoes, carrots, celery, radishes, onions and other vegetables, but also used to cut frozen meat.
  • the drum acts as Centrifuge, on the inside of which a plurality of axially extending Driver ribs are arranged, which ensure that this in the drum the material being cut follows the rotation of the drum without slippage. Furthermore the driving ribs have the task of cutting the slices exert the necessary counterforce on the material to be cut.
  • the material to be cut is usually fed via a hopper, from which the material to be cut is fed is directed to a central opening in an end face of the drum.
  • the opposite Front of the drum, whose axis of rotation is usually horizontal is closed, so that the material to be cut with the drum rotating can only emerge through the openings in the drum shell.
  • the machines have according to the state of the art, one often follows the circular knife set further cutting device, which is designed in the form of a so-called chopping roller.
  • chopping roller With this chopper roller, with several arranged around its circumference bar-shaped knives and with their axis of rotation parallel to the circular knife set is aligned, the emerging from the circular knife set and divided into cubes or cuboids over a strip of counter-jute.
  • a disadvantage of the known machines is that they are particularly sensitive Cuts when passing through the circular knife set with a large pressure load are exposed. This stems from the fact that in the cut slices penetrating circular knives inevitably cause material to be cut, which results in compression of the material to be cut. Especially with pressure sensitive and juicy cutting goods, such as onions therefore to an undesirably large juicing, which is a clear lack of quality the cut strips or cubes can be viewed. Aspirations, the pressure load by reducing the thickness of the circular knives are reduced by a Minimum material thickness, which should not be undercut, sets very narrow limits.
  • the invention has for its object to propose a cutting machine with which is also sensitive and juicy cutting goods without quality reduction in strips or cubes can be cut.
  • this task solved according to the invention in that in the conveying direction of the cut slices at least two sets of circular knives are arranged one behind the other, their shafts run parallel to one another, the circular knives of the second set of circular knives perpendicular to the direction of conveyance to the circular knives of the first circular knife set are staggered.
  • the pressure load on the material to be cut is, for example when using two circular knife sets arranged one behind the other halved, because in each of the two stages connected in series only the Half of the total circular knives available on both knife sets with the Product are engaged. This way the juice loss can be reduced in this regard sensitive cutting goods can be significantly reduced.
  • the circular knives of the first set of circular knives fit into the spaces between extend the circular knives of the second circular knife set, the distance the axes of rotation is dimensioned approximately so that the in a plane parallel to contour lines of the circular knives of the two circular knife sets projected onto the circular knives in a tangential plane to the outer surface of the two waves cut the circular knife sets.
  • Circular knife sets a slotted plate is provided, which the cross section of the conveyor Axes of rotation of the circular knife sets limited and by the circular knives of the Circular knife sets in slots, which are adapted in length and width to the circular knife are permeated. In this way, an unwanted intrusion can occur from cutting material in areas between the shafts of the circular knife sets prevented and thus consistent product management can be achieved.
  • the machine 1 shown in Fig. 1 for cutting vegetables in particular Cube has a drum 2 with a horizontal axis of rotation on a funnel 3, in an opening, not shown, within an end face of the drum 2 opens, can be equipped with material to be cut. That due to the centrifugal force radially through Breakthroughs in the drum 2 emerging cutting material is fixed with the help of a knife sliced with a machine frame.
  • This Disks are then using two circular knife sets 4 and 5, whose Axes of rotation run parallel to the axis of rotation of the drum 2, cut into strips. Subsequently, these strips are not covered with a cover 6 visible chopper divided into cubes. The cubes leave the machine 1 through the outlet cross section of an ejection chute formed by the cover 6.
  • the drum 2 has four driver ribs 7 provided, which cause the axially introduced material to be cut in the edge regions of the drum cross section approximately in synchronism with the drum 2 emotional.
  • the two circular knife sets 4 and 5 In an area to the side of the drum 2 are at an angle to one another the two circular knife sets 4 and 5.
  • the nascent disks, the - starting from the cutting edge 8 of the fixed knife 9 - the Leave drum 2 in the tangential direction, are successively by the Circular knife sets 4 and 5, the outer contours of which are not shown to scale in FIG. 2 are cut into strips.
  • a chopper 10 with five distributed in the circumferential direction and parallel mutually arranged cutter bars 11, which with the rear edge 12 of the Knife 9 work together in the form of a shear bar.
  • the speed of the chopper roller 10 are those emerging from the second circular knife set 5 Stripes divided into cubes or cuboids.
  • a cylinder 13 surrounding the drum 2 is in an exit area 14 which is fixed in the direction of rotation (arrow 15) of the drum 2 Knife 9 is upstream, expanded spirally. This is done after controlled passage of the material to be cut through the respective opening in the drum 2 cutting a disk of thickness 16. As a result of the centrifugal force the material to be cut is always in the outlet area on the inner wall 17 of the cylinder 13, which is increasingly moving away from the axis of rotation of the drum 2. With help an adjusting device 18, the thickness 16 of the slices can be varied.
  • the cut slices then pass through two sets of circular knives 4 and 5, whose axes of rotation are parallel to one another 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 in the direction of the axes of rotation of the circular knife sets 4 and 5 delimited by a slotted plate 22, in the slots of which Penetrate circular knives 19 and 20.
  • the slotted plate 22 prevents the cut Streaks due to friction on the flanks of circular knives 19 and 20 from the knife 19 is lifted and on a circular path in areas between the waves of the circular knife sets 4, 5 or behind the wave of the second Circular knife set 5 are moved.
  • the circular knives 19 extend of the first set of circular knives 4 in the spaces between the circular knives 20 of the second circular knife set 5 or vice versa. This overlap of the Circular knives 19 and 20 in one connecting the axes of rotation of the circular knife sets 4 and 5 Level is achieved that the material to be cut after an exit from the Circular knife set 4 immediately enters the circular knife set 5.
  • the strips are made using a Chopping roller 24 rotating about a parallel axis of rotation is divided into cubes.
  • the chopper 24 has five over the circumference of a roller body which is star-shaped in cross section 25 distributed bar knives 26, which at a close distance pass rear edge 27 of the slotted plate 22 and after with its front edge 28 Traversing the conveying cross section with the rear edge 29 of the knife 9 in Interact with the shape of a shear bar.
  • a pressure load on the material to be cut does not take place due to the chopper roller because of the large free length of the Knife bar 26 in connection with the height of the ribs 30 of the roller body 25 there is enough space for the cubes to fall off.
