Definitions

  • the present invention relates to the production of cheese of the Gouda type, i.e. pressed cheeses ideally having a rigid and tight structure with relatively few and middle-sized holes, typically of pea-size.
  • These cheeses may be produced in a relatively simple and rapid manner by feeding the cheese coagulum from the curdling tank into an upright perforated drain tube, from which the whey is drained off, such that the drained cheese mass can be delivered to an underlying cheese mould, which is brought to a cheese press for further processing of the cheese mass.
  • the cheese coagulum should undergo a pre- pressing in a special prepressing vat as otherwise required.
  • the drainage chamber has to be connected with a CIP cleaning system, viz. by way of an upper and a lower pipe connection.
  • the lower connection can be used also for the discharge of the drained whey, while the upper connection is used only for the circulation of the CIP cleaning liquid.
  • the platform is urged upwardly, causing the cut-off coagulum block to be compressed against the lower side of the knife blade, e.. through 30-60 seconds, whereby further whey is driven out of the block.
  • another cylinder is actuated so as to push the block laterally off the platform.
  • the main function is just the same, but the compressed block member is discharged laterally by the same piston plate that has been used for the compression, in that the entire receiving system beneath the drain tube is pivotally arranged, such that the piston plate, when the system has been turned 90°, can be used to eject the block laterally to some receiver or conveyor means.
  • the said block members are still cut off from the coagulum column with the use of knife plate means, but use is made of two opposed knife plate halves, which are introduced from opposite sides, such that their cutting edges will meet at the middle of the lower drain tube mouthing, thus not caus ⁇ ing any compression against the respective opposite areas of this mouthing, or for that sake, against or between each other.
  • the cut— off block members are not subjected to any immediate compression, once they have been cut off. To the contrary, they are caused to be deposited in shape retaining receptacles or intermediate moulds that are only slightly larger, such that the block members will be free to expand radially without any building up of local compressions, in response to further axial compression or narrowing.
  • the block members cut off from the lower end of the coagulum column are not displaced laterally in any free condition, but are received in an intermediate mould, which is carried, horizontally, into a delivery position, from which the block member can be transferred vertically to an underlying, final cheese mould, in which the block member can finally be processed.
  • this inter ⁇ mediate mould is placed on a carrousel together with one or more similar moulds, whereby it is possible to arrange for some further general compression of the block members without restricting the capacity of the system.
  • Fig. 1 is a perspective, schematical view of a system according to the invention
  • Fig. 2 is a perspective view of a knife plate element used therein, and
  • Fig. 3 is a side view of a carrier part shown in Fig. 1.
  • the already discussed drain tube or tubular sieve is shown at the top, standing on an apparatus cabinet 2 and designated 4. It comprises an outer tubular housing 6 in which there is arranged a coaxial sieve pipe 8, the perforations of which are preferably made as very narrow, vertically oriented slots 10, e.g. having a width of only 1 mm and a height of about 10 mm.
  • the sieve pipe is divid ⁇ ed into three sections, each having a lower outlet pipe 12 from the chamber between the outer housing 6 and the sieve pipe and an upper supply pipe 14 leading to the same chamber.
  • each outlet pipe 12 there is mounted a filler ring 16, the underside 18 of which is conical outwardly and upwarddly as clear ⁇ ly shown in the annexed detailed view.
  • the mouthing of the supply pipe 14 has its upper limit located next to the outer circumference of the ring 16 and its lower limit located in level with or slightly beneath the underside level of the ring 16 immediately next to the sieve pipe 8.
  • a coagulu /whey mixture is fed to the sieve pipe 8, the bottom of which is temporarily closed by a pair of horizontal knife plates 20, which, from the positions shown, are pushed together so as to form a bottom closure of the pipe 8.
  • the whey or the major part thereof escapes through the slots 10 and is brought to fill up the outer chambers in the single sections of the sieve pipe 4, from which excess whey may then be discharged through the pipes 12 , with the use of a suitable sensing and controlling equipment.
  • the bottom plate 24 in the mould 22 can be lifted by means of an underlying lift unit shown as a cylinder 26, whereby the bottom plate at the outset can be locat ⁇ ed just underneath the level of the knife plates 20. Then the bottom plate can be lowered in a controlled manner, thus lowering the entire coagulum column in the pipe 8 until the desired height portion has been receiv ⁇ ed in the mould 22.
  • the bottom plate 24 is not used for compressing the block against the underside of the knife plate.
  • the receiver mould 22 is arranged on a rotatable support 28 which can be rotated horizontally about a vertical, controlled turning shaft 30, such that the intermediate mould 22 can be swung into a delivery position, in which the cheese body accomodated in the mould 22 will be located just above a regular cheese mould 32, which has been fed to its position by means of a feeding conveyor 34 extending into the cabinet 2 through a wall opening 36 therein. Above this position there is provided, in or on the cabinet 2, a working cylinder 38, the piston rod of which is connected with a pressure plate 40, which can be urged down for rejection of the cheese member from the intermediate mould 22 to the underlying cheese mould 32 when the bottom plate 24 has been removed as describ ⁇ ed below.
  • On the rotary support 28 are mounted two opposed intermediate moulds 22, which may thus operate alternatingly.
  • the perforated bottom plate 24 is ressted loosely in a flat recess in a slid ⁇ ing plate 23 underneath the support 28, the flat recess having a bottom hole that allows the underlying lift system 26 to lift the bottom plate as described.
  • the sliding plate 23 is connected with a cylinder 25, by means of which it can be displaced to a positon in which it is fully retracted from the lower end of the associated receiver mould 22.
  • the cylinder 25 is actuat ⁇ ed to this effect when the mould is ready for the transfer of its cheese body to the underlying mould 32.
  • the cheese mould 32 is moved out of the cabinet by means of a conveyor 38, from which the mould and the subsequent moulds are delivered to a proper cheese press, this not being illustrated further.
  • the whey that is pressed out of the cheese members by the action of the pressure plate 40 will just fall down to the bottom of the cabinet 2, and the drained off whey can then be removed by a lower drainage pump 42.
  • the knife plates 20 may still give rise to edge fermentation problems, viz. in that by their planar friction against the top side of the block member in the mould 22, they may cause a certain cutting-up of the surface of this block member. According to the invention this may be counteracted by way of the undersides of the knife plates having a depression just behind the root of the inclined facet forming the cutting edge, as shown in Fig. 2.
  • the cutt ⁇ ing edge is denoted S, the said depression R, the inclined facet F, and the said root P.
  • the cheese blocks may particularly well carry out a free fall by their delivery from the mould 22, but according to the invent- ion this may be avoided by the pressure plate 40 being made as a hollow body having a perforated bottom plate 41 and a connection through a conduit 44 to a vacuum source. Thereby a fixed coherence between the pressure plate 40 and the cheese block can be ascertained, until the block has reached the bottom of the mould 32, where ⁇ after the vacuum can be relieved and the pressure plate 40 lifted to be made ready for the next operation.
  • the final moulds 32 should be preheated in the range of 32-35° C, as a local cooling of the outermost portion of the cheese blocks may easily contribute to the said edge fermentation.
  • the "loading down cylinder" 26 in a preferred embodiment, is constituted by a screw spindle system driven by a step or servo motor, whereby it is possible to control the lowering of the plate 24 for stopping it in accurately controlled positions.
  • the "down measuring" of of the coagulum will be decisive for the thickness of the cheeses. This down measuring can well be controlled by simple and inexpensive means, but with a resulting accuracy which is not too good. With the invention it has been recognised that it is advantageous to use the more expensive spindle system, as this will currently produce an improved operation profit.
  • the vertical movements of the load-down plate 24 may be effected by an air cylinder, while the said spindle sysstem is only used for the required height adjustments of a lower stop for the movable system.

Abstract

D'après un procédé connu, on prépare la masse de fromage devant remplir des moules à fromage en introduisant le mélange de base de petit lait et de caillebotte dans un tube de drainage perforé, à partir duquel on retire le petit lait et on fait circuler la masse de fromage restante vers le bas pour la recueillir dans des moules à fromage qu'on transfère ensuite pour effectuer le pressage ordinaire des blocs de caillebotte obtenus. On a cependant découvert que ce procédé présente différents problèmes en ce qui concerne la fermentation périphérique et l'invention permet d'apporter une solution à ces problèmes au moyen d'un système de production tout à fait nouveau et extrêmement efficace.
