Definitions

  • the present invention relates to a method and a device for disintegrating matter and particularly foodstuffs.
  • the device is mainly intended for the disintegration of foodstuffs in the form of larger pieces or blocks, such as sausages and compressed meats, and in the first place cheese.
  • US Patent No. 3,811,627 relates to a pigment rod mill intended to be incorporated into a plastic material by means of a rotary grating cylinder against which the material is advanced. It should be noted that the milling cylinder only performs a rotational movement, its axis being fixed and is not driven back and forth. The material to be cut is forced into a narrow longitudinal passage 412 (Fig. 1) which would cause blockage for a material with a sticky consistency such as a cheese with a high fat content or a piece of cold meats. This device would not solve the problem of simultaneous debitage and metering of such products on moving objects.
  • US Patent No. 3,831,866 relates to a device for grating conventional cheese comprising a flat grater performing a back-and-forth movement against a block of cheese.
  • This device does not include a rotary cutting member. It is undoubtedly suitable for hard and dry cheeses but would not be usable for soft and sticky cheeses with a high fat content which would quickly fill the holes in the grater. Consequently, it would not be able to carry out the disintegration and the determination reliably simultaneously.
  • the present invention makes it possible to eliminate the aforementioned drawbacks and to obtain a uniform disintegration of foodstuffs which were previously difficult to use from this point of view.
  • the process and the device according to the invention are specially suitable for the disintegration of cheese, but also other foodstuffs in pieces, such as minced meat and pressed ham, can advantageously be disintegrated according to the invention.
  • the devices already known for disintegrating different foodstuffs into pieces have most often been of completely different models, depending on the type of foodstuff to be processed. It would be highly desirable from a practical and economical point of view that different types of food could be processed essentially in the same apparatus, in which only a few parts would need to be replaced to adapt to the different mechanical and rheological properties of different food.
  • the present invention achieves this object, and the same apparatus can be used for different foodstuffs, such as cheeses, meats and cold meats, for example pressed ham and minced meat, sausages being larger sausages alone, or several small sets, and other materials, only the organs used for the disintegration itself need to be specially adapted to the type of foodstuff treated.
  • the invention therefore relates to a material disintegration method, in which the material is advanced towards a driven disintegration member, which is caused to perform an alternating movement substantially parallel to a surface of the material, with simultaneous cutting of material from this surface.
  • the driven disintegration member is constituted by a rotary screw whose axis of rotation is substantially parallel to the worked surface and whose thread is provided with a cutting edge which is directed forward in the axial direction where the thread seems to move when the screw turns.
  • the invention also relates to a material disintegration device comprising a disintegrating member driven and arranged to receive an alternating movement substantially parallel to a surface of the material with simultaneous cutting of material from this surface as well as a transport device for advancing the material towards the disintegrating member, characterized in that the driven disintegrating member is constituted by a rotary screw whose axis of rotation is substantially parallel to the worked surface and whose spinning is provided with a cutting edge which is directed forward in the axial direction in which the thread seems to move when the screw rotates.
  • the screw is provided with .two threads in opposite directions, the two directions of threading each occupying part of the length of the screw, preferably each half.
  • FIG. 1 shows a schematic overview of a device according to the invention
  • FIG. 2 shows a detailed view of a preferred embodiment of the disintegration member
  • FIG. 3 shows a section of a detail of the disintegration member according to FIG. 2.
  • the device consists in its main parts of a frame 1 supporting a transporter 2 for a foodstuff in the form of a block 3, for example a cheese.
  • Guide devices 4 are also arranged for correct feeding.
  • the conveyor is preferably in the form of a chain transporter with a toothed conveyor chain 5 and is driven by a ratchet mechanism 6, the control arm 7 of which is actuated by a compressed air cylinder 8.
  • a disintegrating member 9 is driven by a motor 12 by means of the pinion 10 via the intermediate wheel 11.
  • the disintegrating member is indicated as a rotary cutting member, and especially as a rotary screw of the type shown on fig. 2.
  • the cutting member is brought in front of the front surface 13 of the foodstuff block and is fixed to a support 14, and everything is together can be moved up or down along the guide bars 15 by means of the piston rod 16.
  • the displacement is carried out by means of the apparatus 17 shown diagrammatically and which is controlled by the adjustment unit 18.
  • the particles 19 of the foodstuff which are obtained during disintegration fall by the hopper 20 on a food product 21, for example a pizza, which is brought by a conveyor, for example a conveyor belt, which is indicated at 22.
  • a detector 23, which acts on the adjustment unit 18, makes it possible to ensure that no disintegration occurs if there is nothing on the conveyor belt to receive the disintegrated product.
  • the adjustment unit 18 makes it possible to control both the advancement of the conveyor 2 as well as the transport and the drive of the torque member 9 so that an appropriate length of the foodstuff block 3 is advanced when the member cutting is in its upper position, or in its lower position, after which, the cutting member is lowered, or mounted, and driven so that the disintegration occurs.
  • the ratchet mechanism 6 prevents the food entry block from rebounding during the action of the cutting member. It is not always necessary that the cutting member is only driven when it is lowered, or mounted, but this constitutes a preferred embodiment.
  • the drive of the conveyor 2, of the disintegration member 9 and of the upward and downward movement of the latter can be electric or hydraulic, but is preferably pneumatic.
  • the reason for this is that a device for treating food is often placed in a humid atmosphere, and must be capable of being thoroughly cleaned and disinfected, for example by means of high pressure washing. This can then lead to difficulties for an electrical device, in the form of short-circuits and spurts, which can also involve risks for personnel.
  • Adjustment units for controlling pneumatic apparatus as described here are already known to those skilled in the art and the latter can assemble them from commercially available units. Hydraulic equipment can be used provided that a hydraulic fluid compatible from the point of view of food technology, for example edible oil, is used.
  • Figs. 2 and 3 show a specially preferred embodiment of the disintegration member according to the invention.
  • this disintegration member has the form of a screw 51 with a drive end 52 and a bearing end 53.
  • the screw is provided with a thread 54 which, according to the specially preferred embodiment which is shown in the drawing, is divided into a part turning to the right 54a and a part turning to the left 54b.
  • FIG. 3 which is a section along line A-A of FIG. 2
  • the thread has a cross section essentially in the shape of a trapezoid and has a cutting edge 55 at one of its upper edges which has a certain relief angle 56 in the axial direction of the screw.
  • a certain number of advantages are obtained by dividing the thread of the screw into two parts facing one another, which are therefore homothetic.
  • the material delivered will be brought to the middle of the screw to be collected there before falling into the hopper, so that there is less risk of loss.
  • the disintegrated material will be remixed and this can be taken advantage of in that several smaller blocks of material of different kinds, for example different kinds of cheese, can be brought next to each other and, simultaneously, disintegrated and remixed. Thanks to threads in opposite directions, a balance is finally obtained axial stresses on the bearings of the screw at the two ends thereof.
  • the screw thread is divided into two parts of opposite directions, and that only one thread direction can also be used.
  • the disintegrated material is then sent to one of the sides in the direction of movement of the thread, to be collected therein in an appropriate manner.
  • the degree of disintegration of the processed food product is determined by the shape, size and speed of the screw.
  • foodstuffs such as cheese, pressed ham and frozen meat can be disintegrated in the form of more or less fine shavings or the like. It has been found that a higher speed of the screw and a lower speed of movement of the screw in the vertical direction gives thinner shavings.
  • a suitable regime has been found to be 3000-4000 rpm. and an appropriate speed in the vertical direction, 5-20 cm / sec. However, values outside these ranges can be used, and can be determined by a person skilled in the art for adaptation to the consistency of the material treated in each case.
  • a thread diameter of 2-5 cm is suitable and particularly satisfactory results have been obtained with a diameter of approximately 3 cm.
  • the diameter of the screw determines the width of the shavings formed, so that a larger diameter gives wider shavings.
  • the thread pitch of the screw is also important and here it turned out that a value of 3-6 cm / turn was appropriate. If the pitch exceeds about 6 cm, the material leaves the screw badly, while a too small pitch gives very small chips.
  • the cutting edge on the screw thread can have a clearance angle of 0-5 degrees and here a value of around 2 degrees has been found suitable.
  • the length of the portion which delivers is not particularly critical, but can be adapted to possibly standardized dimensions of the foodstuffs in pieces which are processed.
  • Each of the screw threads can also have several inlets, which makes it possible to have a plurality of threads oriented in each direction. This results in further disintegration.
  • the feed rate of the disintegrated material is important, so that a higher feed rate results in larger material chips.
  • the material is advanced intermittently when the disintegration member is in its upper position, and an advance of approximately 3 mm per stroke has given good results under normal conditions.
  • the direct metering of material which is obtained with a screw as a cutting member according to the invention makes it possible to avoid any other handling of the disintegrated material, which saves work and reduces material losses.
  • a satisfactory and uniform spreading of the disintegrated material is obtained in that the latter descends into a hopper to fall on a prepared food product, for example a pizza or a gratin, which product is advanced under the device on a conveyor. For the best result, it is appropriate to adapt the size and shape of the hopper to the food product to receive the disintegrated material.
  • a rotary screw as a cutting member has proved to be particularly suitable for the disintegration of cheese, and also of pressed meats, such as ham or head cheese of different types, and in the form of blocks. of appropriate size.
  • Food products can be frozen, refrigerated or have room temperature, and in some cases the temperature affects the processing properties during disintegration.
  • it has been found appropriate to cool the cheese, since it then obtains a less sticky consistency.
  • Cheese with 45% fat on dry matter and even more can however be disintegrated without any problems at room temperature.
  • the supply of material intended to be disintegrated can be continuous.
  • the blocks of cheese can be welded together by means of a binder composition suitable for food use upstream of the disintegration device, so that there is no interruption in the food.
  • the purely technical design of the device according to the invention is conventional and can be easily determined by those skilled in the art.
  • the helical cutter is preferably made of stainless steel with a composition suitable for knives.
  • the edges of the cutting member do not need to be sharpened particularly often, since the majority of food products have a very weak abrasive effect.
