Definitions

  • the invention relates to a method for dividing block-shaped food products into individual pieces, in particular cubes or cuboids.
  • Such methods known in the art are used to break up suitable food products, in particular cheese, into relatively small, for example cube-shaped, pieces, the edge length of a piece being, for example, between 5 mm and 30 mm.
  • said processes are used to break a block of relatively soft cheese, especially feta cheese, into cubes having an edge length of about 15 mm.
  • feta cheese other types of cheese may also be used, e.g. Blue cheese, semi-hard cheese or the like can be divided.
  • processing of other products such as e.g. Pies is possible.
  • the cube-shaped or cuboidal pieces produced by the known methods should generally be offered and sold in portions with a total weight within specified tolerances, for which reason the pieces produced are supplied as bulk material to cup scales, by means of which the respective desired portions are filled in accordance with the predetermined target weights ,
  • the weight of a serving can only be adjusted with the accuracy of the weight of a single piece, which often results in a packaged portion having a weight that is higher than it should be, which of course causes an economic disadvantage.
  • Another disadvantage of the known method is also that after dividing the food product into individual pieces no orderly processing is possible because a weight-accurate packaging of portions can be done only by handling the pieces produced as disordered bulk material.
  • An object of the present invention is to improve the known methods in such a way that portions can be produced as accurately as possible in weight and without damage or deformation of the pieces produced. In particular, an orderly further processing of the pieces produced should be possible.
  • the weight aspect is thus considered before or during the production of the individual pieces and not only in a subsequent weighing of the pieces produced. Since, according to the invention, the weight of the slices to be cut off by a block is determined before the respective cutting process, the weight of the quantity of all the pieces produced from the respective slice is also known (at least largely identical). Consequently, the invention makes it possible, for example, to cut off a slice with a portion weight to be achieved ultimately from the block and to assign all the pieces produced from this slice to the respective portion so that it then has exactly the desired weight. Likewise, it is of course also possible to form a portion of all those pieces which are obtained from several slices which are successively separated from the block. The weight of such a portion then corresponds to the total weight of the respective discs.
  • the essential difference from the first variant is that, according to the second variant, it is no longer compulsory to assign all pieces obtained from a single slice to a serving. Rather, it is possible to assign the pieces obtained from a slice also two or - for very large slices or very small portions - more than two portions. Those pieces, each one together However, they are always assigned to only one serving, which means that individual rows are not split into different portions.
  • discs are cut with a predetermined weight of a block, but the discs themselves are divided into individual rows of pieces that run parallel to each other, in particular in the form of "transverse rows" perpendicular to a conveying direction, and either have a predetermined weight or their weight is determined afterwards. It is preferred in this case if the discs are divided into rows, which have a predetermined weight. This can be achieved by making the width of the rows cut off from the slices variable. Since the volume and / or dimensions and weight of the block to be dispensed as well as the width of each disc are known, the width of a row to be separated from a disc before separation can be calculated to give a predetermined weight of the row.
  • the second variant of the invention it is thus possible to produce portions with a finer graduated total weight than with the first variant of the invention, since the total weight does not have to be a multiple of a disc weight as in the first variant of the invention but only a multiple of a row weight.
  • the total weight does not have to be a multiple of a disc weight as in the first variant of the invention but only a multiple of a row weight.
  • even rows with divergent weights of a slice can be cut off, so that here also a fine adjustment of the total weight of portions to be generated can be done.
  • the slices separated from the block are first divided into several parallel longitudinal strips, whereupon the longitudinal strips are then divided into rows of individual pieces.
  • the cuts, with which the slices are divided into longitudinal strips and the sections with which the longitudinal strips are divided into the individual pieces generally run at right angles to one another, so that the totality of the cuts made per slice ultimately produce a kind of lattice structure.
  • the longitudinal strips and the pieces are hardly moved relative to each other so that the pieces produced are still in disc formation even after all cuts have been made. Since, according to the invention, the weight of the disc or of all pieces produced from the disc at this time is known, it becomes possible to process the pieces in the mentioned disc formation in an ordered manner.
  • the first division of the disc in longitudinal strips is carried out in an advantageous manner by means of mutually parallel longitudinal cutter, in particular by means of parallel arranged cutting wires or by means of parallel slender knife.
  • the longitudinal sections are made if they are performed simultaneously.
  • it is preferred if the discs are moved on a conveyor in the conveying direction against the slitter or pushed through the cutting wires.
  • Such cutting devices are known from the prior art.
  • the division of the parallel juxtaposed longitudinal strips of a disc in transverse rows of individual pieces is carried out in an advantageous manner by means of a cross cutter, in particular by means of a cutting wheel.
  • the cross cutter is in the conveying direction of the discs behind the Long cutters provided.
  • the feed of the conveyor, with which the longitudinal strips are conveyed and the times at which the cross cutter cuts, can be coordinated so that cross rows of individual pieces with divergent widths can be generated.
  • the dimensions of all transverse rows in the conveying direction are preferably substantially the same for each pane. In this way it is achieved that the pieces produced from a disc are substantially equal to each other. Thus, in particular the generation of too small pieces in edge regions of the disc can be avoided. This is true even if successive discs have different sizes, since the dimensions of the transverse rows in the conveying direction from disc to disc can of course vary.
  • the slicing of the block into slices can also take place in such a way that only slices are produced which deviate only slightly in their thickness from one another. This avoids that e.g. as the last disc only a very thin disc remains, which would then no longer be subdivided into such cubes, which correspond in size to those cubes, which were obtained from the other discs of the block.
  • the dimensions of the transverse rows in the conveying direction also within a To change disc when the transverse rows of a slice are assigned to different portions and, accordingly, the weight of a certain portion associated transverse rows for each portion must be set individually.
  • a packaging machine may be designed in particular for the production of thermoformed packaging, in which the individual pieces are then still packed in disc formation.
  • Fig. 1 shows a schematic side view of a lying on a base 2 cheese block 4, which can be pushed by means of a slider 6 in the direction of a conveyor belt 8.
  • a vertically movable cutting blade 10 is disposed above the cheese block 4, by means of which slices can be cut from the cheese block 4, said cut slices by means of suitable, in Fig. 1
  • Unillustrated derailleur can be tilted by about 90 ° and then fall on the conveyor belt 8.
  • the cheese block 4 is weighed by means of a balance, not shown, so that the total weight of the cheese block 4 is known. Likewise, its volume and / or dimensions are determined prior to slicing the block of cheese. If the cheese block 4 has a constant cross section over its entire length, it is sufficient to determine the volume and the length of the cheese block, since in this case it is uniquely determined which weight has a length unit of the cheese block 4 or a slice to be separated from it.
  • the cross-section over the length of the cheese block 4 is not constant, its entire dimensions must be determined prior to slicing, so as to be able to calculate from these dimensions and the total weight of the block of cheese which thickness a slice to be sliced must have, by a predetermined weight receive.
  • the block of cheese has a substantially homogeneous consistency so that the weight of a unit of length or a slice of cheese block 4 can be calculated as a function of the external dimensions of cheese block 4 and its total weight.
  • suitable examination methods for example by means of X-ray methods, the density distribution of an inhomogeneous block of cheese along its length is determined in addition to its dimensions and weight, so that discs of a predetermined weight can also be cut off from such an inhomogeneous block of cheese.
  • the separated from the block of cheese 4 slices 12 fall, as already mentioned, on the conveyor belt 8 and are transported by this from the pad 2 in the direction of a cutter 14, 16. While In this transport, the discs 12 pass under a sensor 18, by means of which the respective length of the individual discs can be determined.
  • the cutting device 14, 16 is provided, which consists of a cutting grid 14 and a cutting wheel 16, wherein the cutting grid 14 is preceded by the cutting wheel 16 in the transport direction of the discs 12.
  • the cutting grid 14 consists essentially of a frame in which from top to bottom parallel cutting wires are stretched, which preferably have a constant distance from each other.
  • the respective foremost on the conveyor belt 8 located disc 12 is pushed in the horizontal direction by the substantially perpendicular cutting wires of the cutting grid 14, so that this disc 12 is divided into mutually parallel longitudinal strips, which according to the representations in Fig. 1 and 2 extend from left to right in the conveying direction.
  • the longitudinal strips are behind the cutting grid 14 close to each other, so that they are ultimately still promoted in disc formation.
  • the subsequent in the conveying direction directly to the cutting grid cutting wheel rotates about a in the plane of the Fig. 1 and 2 lying rotational axis 22, wherein it consists essentially of an annular frame 24 (FIG. Fig. 3 ), in which, for example, between three and ten cutting wires 26 are stretched in a star shape between the axis of rotation 22 and the annular frame 24. It would also be possible to clamp in the annular frame 24 only one or two cutting wires.
  • the cutting wheel 16 can be driven intermittently in angular increments, so that a separation of a transverse row of pieces from the mutually parallel longitudinal strips can always take place exactly when the longitudinal strips were conveyed so far into the cutting wheel 16 that generates the respective desired width of the transverse rows can be.
  • a discharge belt 28 is arranged, by means of which the cut into pieces slices 30 can be further fed in disk formation further processing.
  • the cheese block 4 is measured. In addition, his total weight is determined.
  • the length of this disc is then determined, so that with respect to this disc 12 then both its length and its weight is known. From this information can be calculated by known methods readily how far the disc 12 and the longitudinal strips produced from it must be moved into the cutting wheel 16 in order to separate a transverse row of pieces, which in turn has a predetermined weight.
  • the discs 12 are pushed by the slider 20 through the cutting grid 14, so that there is a division of the discs 12 in longitudinal strips, which extend parallel to the conveying direction.
  • Immediately behind the cutting grid 14 then takes place a cutting of transverse rows by means of the cutting wheel 16, wherein a cut is always carried out when the slider 20 has pushed the longitudinal strip produced by the cutting grid 14 far enough into the cutting wheel 16 into it.
  • the discs 12 are then in disk formation in the form of pieces, as this Fig. 2 with respect to the disc 30 can be removed.
  • the cuts produced by the cutting grid 14 and the cutting wheel 16 ultimately produce a grid structure in the pane 30.
  • cutting grid 14 and cutting wheel 16 are operated in such a way that each slice 12 is divided into roughly equal pieces (see FIG Fig. 2 , Disc 30).
  • the fragmented disc 30 has substantially the same weight as at the time of its separation from the cheese block 4, so that it can be further processed as a portion with a precisely defined weight.
  • Fig. 4 illustrates the first variant of the invention and shows three arranged on a discharge belt 28 fragmented disks 30, each broken disk 30 forms exactly one portion P 1 , P 2 and P 3 .
  • Fig. 5 illustrates a possible implementation of the second variant of the invention, in which each of the pieces of 1.5 piece slices form a portion.
  • the three located on the outlet belt 28 pieced Discs 32, 34 and 36 are arranged one behind the other in the conveying direction A.
  • a first portion P 1 is formed from all pieces of the fragmented disk 36 and the first 16 pieces or four transverse rows of the second piece in the conveying direction splitted disk 34.
  • Portion P 1 has the known weight of the fragmented disc 36 plus half the weight of the fragmented disc 34. Accordingly, the portion P 2 has half the weight of the fragmented disc 34 plus the total weight the broken disk 32.
  • the fragmented disc 34 must be separated in the further conveying process in two spatially spaced halves so that they can be supplied to the different portions P 1 and P 2 .
  • the first half of the disc 34 is then cut into pieces by means of the cutting wheel 16, whereupon these pieces are conveyed by the discharge belt 28 slightly away from the cutting wheel 16 before the cutting wheel 16 breaks up the remaining disk 34 into pieces.
