Description

« DISPOSITIF POUR LA PRODUCTION, DANS UNE CUVE HEMISPHERIQUE, DE CAILLE TRANCHE EN MORCEAUX EN VUE DE L'ELABORATION DE FROMAGE » "DEVICE FOR THE PRODUCTION, IN A HEMISPHERIC TANK, OF QUAIL SLICE IN PIECES FOR THE PREPARATION OF CHEESE"
La présente invention concerne un dispositif pour la production de caillé tranché en morceaux en vue de l'élaboration de fromage .The present invention relates to a device for the production of curds cut into pieces for the production of cheese.
Le caillé, qui résulte de la coagulation du lait sous l'action de la présure et des ferments lactiques, doit être tranché avec beaucoup de soin pour qu'il puisse se séparer convenablement du sérum. Le tranchage est en effet une opération essentielle pour la réussite qualitative et quantitative du fromage, que ce dernier soit à pâte cuite ou non cuite.The curd, which results from the coagulation of the milk under the action of rennet and lactic ferments, must be carefully sliced so that it can properly separate the serum. Slicing is indeed an essential operation for the qualitative and quantitative success of the cheese, whether the cheese is cooked or uncooked.
Les dispositifs et procédés de tranchage utilisés actuellement ont fait l'objet de nombreux perfectionnements au cours des dernières années, mais ils ne donnent pas encore entièrement satisfaction. Par exemple, ces techniques produisent des morceaux dont les dimensions varient généralement en fonction de leur position dans le caillé. Or, il est important que ces morceaux présentent des formes et volumes similaires, sinon identiques. Certaines de ces techniques ont par ailleurs tendance à arracher le caillé pendant l'opération de tranchage et à provoquer des « fines » ou pertes de produit .Currently used slicing devices and methods have been the subject of many refinements in recent years, but are not yet fully satisfactory. For example, these techniques produce pieces whose dimensions generally vary according to their position in the curd. However, it is important that these pieces have similar shapes and volumes, if not identical. Some of these techniques also tend to pull the curd during the slicing operation and cause "fines" or losses of product.
La demande de brevet FR 2 713 886 a tenté de résoudre ce problème en proposant une cuve hémisphérique de tranchage de caillé équipée de deux moyens de tranchage montés pivotants sur des axes solidaires l'un de l'autre. Cependant, ce dispositif ne donne pas encore satisfaction car le tranchage du caillé manque de précision et le risque de création de « fines » est encore trop important.The patent application FR 2 713 886 attempted to solve this problem by proposing a hemispherical curd slicing vat equipped with two slicing means pivotally mounted on axes integral with each other. However, this device does not yet give satisfaction because the slicing of the curd lacks precision and the risk of creating "fines" is still too important.
Un but de la présente invention est donc de résoudre les problèmes cités précédemment à l'aide d'une solution simple à mettre en œuvre, fiable et peu coûteuse.An object of the present invention is therefore to solve the problems mentioned above with a solution that is simple to implement, reliable and inexpensive.

Les figures 1 à 5 représentent un premier mode de réalisation d'un dispositif de production de caillé tranché 1 conforme à la présente invention. Ce dispositif 1 est utilisé dans l'industrie laitière pour assurer rapidement et efficacement le tranchage d'un caillé en petits morceaux, de la manière la plus régulière possible, afin d'éliminer le sérum qu'il contient. Le dispositif de production de caillé tranché 1 comporte principalement une cuve 10 destinée à contenir le caillé à trancher, des premiers moyens de tranchage mobiles 20 et des seconds moyens de tranchage mobiles 30. Chacun de ces éléments va maintenant être décrit plus en détail ci-après. La cuve 10 comprend une paroi hémisphérique comportant une surface interne lisse 11, un fond central 12 et un rebord périphérique supérieur 13 délimitant une ouverture circulaire 14 permettant de remplir et éventuellement de vider la cuve 10. La cuve 10 est de préférence réalisée en métal alimentaire rigide, tel que l'acier inoxydable.Figures 1 to 5 show a first embodiment of a cut curd production device 1 according to the present invention. This device 1 is used in the dairy industry to quickly and efficiently slice a curd into small pieces, in the most regular way possible, to eliminate the serum it contains. The sliced curd production device 1 mainly comprises a tank 10 intended to contain the slicing curd, first mobile slicing means 20 and second movable slicing means 30. Each of these elements will now be described in more detail below. after. The tank 10 comprises a hemispherical wall having a smooth inner surface 11, a central bottom 12 and an upper peripheral flange 13 delimiting a circular opening 14 for filling and possibly emptying the tank 10. The tank 10 is preferably made of food metal rigid, such as stainless steel.
Un anneau supérieur 15 repose sur le rebord 13 et présente sensiblement les mêmes diamètres interne et externe que ce dernier. Cet anneau 15 est mobile en rotation par rapport au rebord 13 sur un axe vertical de révolution XX' passant par le fond 12 de la cuve 10. L'anneau rotatif 15 peut par exemple être en liaison rotative avec le rebord 13 par l'intermédiaire d'un moyen connu (non représenté), tel qu'un roulement à billes ou à rouleaux. La rotation de l'anneau rotatif 15 sur son axe de révolution XX' dans un sens ou dans l'autre selon la flèche Rl de la figure 1 permet de faire pivoter les premiers moyens de tranchage 20 sur 360° selon une première direction de tranchage Fl, comme cela sera décrit ultérieurement.An upper ring 15 rests on the rim 13 and has substantially the same internal and external diameters as the latter. This ring 15 is rotatable relative to the flange 13 on a vertical axis of revolution XX 'passing through the bottom 12 of the tank 10. The rotary ring 15 may for example be rotatably connected to the flange 13 via known means (not shown), such as a ball or roller bearing. The rotation of the rotary ring 15 on its axis of revolution XX 'in one direction or the other according to the arrow Rl of Figure 1 allows to rotate the first slicing means 20 over 360 ° in a first direction of slicing Fl, as will be described later.
Une tige de support 16 s'étend transversalement sur un diamètre de la cuve 10. Plus précisément, la tige de support 16 est solidarisée à l'anneau rotatif 15 au niveau de ses parties d'extrémité 16a et 16b. Cette tige de support 16 porte à la fois les premiers et les seconds moyens de tranchage 20 et 30, comme cela sera expliqué ultérieurement.A support rod 16 extends transversely over a diameter of the tank 10. More specifically, the support rod 16 is secured to the rotary ring 15 at its end portions 16a and 16b. This support rod 16 carries both the first and second slicing means 20 and 30, as will be explained later.
L'anneau rotatif 15 est également articulé sur le rebord 13 de la cuve 10 au niveau de la partie d'extrémité 16a de la tige de support 16, par l'intermédiaire d'un moyen d'articulation de type connu, tel qu'une charnière (non représentée). Cette articulation permet de relever l'anneau rotatif 15 par pivotement selon la flèche Pl de la figure 1, afin qu'il vienne dans la position illustrée sur la figure 2 pour que les moyens de tranchage 20 et 30 puissent être extraits de la cuve 10 après chaque opération de tranchage. Il suffit bien entendu de faire pivoter l'anneau rotatif 15 dans le sens inverse, illustré par la flèche P2, afin d'introduire les moyens de tranchage 20 et 30 à l'intérieur de la cuve 10, par exemple avant chaque opération de tranchage ou lors du transport ou du stockage de la cuve 10.The rotary ring 15 is also articulated on the rim 13 of the tank 10 at the end portion 16a of the support rod 16, by means of a hinge means of known type, such as a hinge (not shown). This articulation makes it possible to raise the rotary ring 15 by pivoting along the arrow P1 of FIG. 1, so that it comes in the position illustrated in FIG. 2 so that the slicing means 20 and 30 can be extracted from the tank 10. after each slicing operation. It suffices, of course, to rotate the rotary ring 15 in the opposite direction, illustrated by the arrow P2, in order to introduce the slicing means 20 and 30 inside the tank 10, for example before each slicing operation. or during transport or storage of the tank 10.
Un bras 17, situé dans le prolongement de la tige de support 16 et au-delà de sa partie d'extrémité 16a, est fixé à l'extérieur de la cuve 10 et de l'anneau rotatif 15. Un contrepoids 18 est fixé à l'extrémité libre du bras 17. Ce contrepoids facilite le relevage de l'anneau rotatif 15 jusque dans la position dressée illustrée par la figure 2. Le contrepoids 18 facilite également l'extraction hors de la cuve 10 des moyens de tranchage 20 et 30 qui présentent chacun un poids non négligeable s' ajoutant à celui de l'anneau rotatif 15.An arm 17, located in the extension of the support rod 16 and beyond its end portion 16a, is fixed outside the tank 10 and the rotary ring 15. A counterweight 18 is fixed to the free end of the arm 17. This counterweight facilitates the lifting of the rotary ring 15 into the erected position illustrated in FIG. 2. The counterweight 18 also facilitates the extraction from the tank 10 of the slicing means 20 and 30. each of which has a significant weight added to that of the rotary ring 15.
L'articulation de l'anneau rotatif 15 est située à proximité de la partie d'extrémité 16a de la tige transversale 16, pour empêcher les premiers moyens de tranchage 20 de venir au contact de la surface interne hémisphérique 11 de la cuve 10 lors des opérations de pivotement de l'anneau rotatif 15 sur son articulation, et pour éviter que le caillé soit abîmé par les premiers moyens de tranchage 20 lors de leur pénétration en lui.The articulation of the rotary ring 15 is located near the end portion 16a of the transverse rod 16, to prevent the first slicing means 20 from coming into contact with the hemispherical inner surface 11 of the tank 10 during the pivoting operations of the rotary ring 15 on its articulation, and to prevent the curd is damaged by the first slicing means 20 during their penetration into it.
Les premiers moyens de tranchage 20 comprennent, dans ce premier mode de réalisation, une barre 21 fixée perpendiculairement au milieu 16c de la tige de support 16 et dirigée verticalement en direction du fond 12 de la cuve 10. La barre 21, qui est verticale lors d'une opération de tranchage, porte des organes de découpage 22 constitués par de fines lames droites équidistantes 23 s 'étendant horizontalement. Ces lames 23 sont parallèles entre elles et fixées les unes au-dessous des autres d'un seul côté de la barre verticale 21. Les lames 23 s'étendent ainsi en direction de la surface interne hémisphérique 11 de la cuve 10, sans toucher ladite surface. En effet, la longueur respective des lames 23 est telle que l'extrémité libre 23a de chacune d'entre elles affleure la surface interne hémisphérique 11 de la cuve 10. Dans cette configuration, les premiers moyens de tranchage 20 sont forment un quart de disque plan dont la périphérie affleure à tout moment la surface interne hémisphérique 11 lorsqu'ils sont introduits dans la cuve 10, et en particulier pendant une opération de tranchage de caillé, comme cela est illustré notamment sur les figures 1 et 5.The first slicing means 20 comprise, in this first embodiment, a bar 21 fixed perpendicularly to the middle 16c of the support rod 16 and directed vertically towards the bottom 12 of the tank 10. The bar 21, which is vertical when of a slicing operation, carries cutting members 22 constituted by fines equidistant straight blades 23 extending horizontally. These blades 23 are parallel to each other and fixed one below the other on one side of the vertical bar 21. The blades 23 thus extend towards the hemispherical inner surface 11 of the tank 10, without touching said area. Indeed, the respective length of the blades 23 is such that the free end 23a of each of them is flush with the hemispherical inner surface 11 of the tank 10. In this configuration, the first slicing means 20 form a quarter disc plane whose periphery is flush at all times the hemispherical inner surface 11 when introduced into the tank 10, and in particular during a curd slicing operation, as illustrated in particular in Figures 1 and 5.
Selon un deuxième mode de réalisation du dispositif de production de caillé tranché 1 illustré sur les figures 6 et 7, les organes de découpage 22 des premiers moyens de tranchage 20 sont disposés de part et d'autre de la barre verticale 21. Plus précisément, les lames 23 s'étendent horizontalement et forment un demi-disque de diamètre légèrement inférieur au diamètre interne de la cuve 10. Les extrémités libres 23a et 23b de chacune des lames 23 affleurent ainsi à tout moment la surface interne hémisphérique 11 lorsque les premiers moyens de tranchage sont introduits dans la cuve 10, notamment lors d'une opération de tranchage de caillé.According to a second embodiment of the cut curd production device 1 illustrated in FIGS. 6 and 7, the cutting members 22 of the first slicing means 20 are arranged on either side of the vertical bar 21. More specifically, the blades 23 extend horizontally and form a half-disc of diameter slightly less than the internal diameter of the tank 10. The free ends 23a and 23b of each of the blades 23 are thus flush with the hemispherical internal surface 11 at all times when the first means slicing are introduced into the tank 10, in particular during a slicing operation of curd.
Dans les deux modes de réalisation ci-dessus, les seconds moyens de tranchage 30 comprennent quant à eux un axe de pivotement 31 s' étendant perpendiculairement à la tige de support 16, entre le milieu 16c de celle-ci et l'anneau rotatif 15. L'axe de pivotement 31 présente ainsi une longueur sensiblement égale au rayon de l'anneau rotatif 15. Les seconds moyens de tranchage 30 comprennent également des organes de découpage 32 qui sont constitués par de fines lames équidistantes 33. Ces lames 33 sont parallèles entre elles et s'étendent perpendiculairement à l'axe de pivotement 31. Dans le cas présent, les lames 33 sont portées par un support intermédiaire 34 parallèle à l'axe de pivotement 31 et maintenu à l'écart de celui-ci par l'intermédiaire d' entretoises 35. Les lames 33 sont disposées d'un seul côté de l'axe de pivotement 31 et s'étendent en direction de la surface interne 11 de la cuve 10 lors d'une opération de tranchage, sans toucher ladite surface. En effet, la longueur respective des lames 33 est telle que l'extrémité libre 33a de chacune d'elles affleure la surface interne hémisphérique 11 lorsque les seconds moyens de tranchage 30 sont introduits puis mis en rotation à l'intérieur de la cuve 10.In both embodiments above, the second slicing means 30 comprise a pivot axis 31 extending perpendicularly to the support rod 16, between the medium 16c thereof and the rotary ring 15. The pivot axis 31 thus has a length substantially equal to the radius of the rotary ring 15. The second slicing means 30 also comprise cutting members 32 which are constituted by equidistant thin blades 33. These blades 33 are parallel between them and extend perpendicular to the pivot axis 31. In this case, the blades 33 are carried by an intermediate support 34 parallel to the pivot axis 31 and kept away from it by the intermediate of spacers 35. The blades 33 are arranged on one side of the pivot axis 31 and extend towards the inner surface 11 of the tank 10 during a slicing operation, without touching said surface. Indeed, the respective length of the blades 33 is such that the free end 33a of each of them is flush with the hemispherical inner surface 11 when the second slicing means 30 are introduced and then rotated inside the tank 10.
Dans cette configuration, les seconds moyens de tranchage 30 forment un quart de disque plan dont la périphérie affleure la surface interne hémisphérique 11 de la cuve 10 lors d'une opération de tranchage de caillé, comme illustré sur les figures 4 et 5.In this configuration, the second slicing means 30 form a flat quarter disc whose periphery is flush with the hemispherical inner surface 11 of the vessel 10 during a curd slicing operation, as illustrated in FIGS. 4 and 5.
Une manivelle 37, disposée à l'extérieur de la cuve 10, est solidaire de l'axe de pivotement 31. Cette manivelle 37 permet, en étant tournée dans le sens de la flèche R2 de la figure 4, de faire pivoter les seconds moyens de tranchage 30 sur 360° selon une seconde direction de tranchage F2 perpendiculaire à la première direction de tranchage Fl, comme illustré par exemple sur les figures 2 à 5.A crank 37, disposed outside the tank 10, is integral with the pivot axis 31. This crank 37 allows, by being turned in the direction of the arrow R2 of Figure 4, to rotate the second means slicing 30 over 360 ° in a second slicing direction F2 perpendicular to the first slicing direction F1, as illustrated for example in Figures 2 to 5.
Selon une variante de réalisation non représentée, les seconds moyens de tranchage 30 peuvent, à l'image des premiers moyens de tranchage 20 illustrés sur les figures 6 et 7, comprendre des organes de découpage 32 constitués par des lames droites 33 s 'étendant de part et d'autre de l'axe de pivotement 31 pour former un demi-disque dont la périphérie affleure la surface interne hémisphérique 11 de la cuve 10 lors d'une opération de tranchage de caillé.According to an alternative embodiment not shown, the second slicing means 30 may, like the first slicing means 20 illustrated in FIGS. 6 and 7, comprise cutting members 32 constituted by straight blades 33 extending from both sides of the pivot axis 31 to form a half-disk whose periphery is flush with the hemispherical inner surface 11 of the tank 10 during a curd slicing operation.
Les figures 8 à 10 illustrent un troisième mode de réalisation du dispositif de production de caillé tranché 1 conforme à la présente invention. Dans cette variante, toutes les lames 23' et 33' appartenant respectivement aux premiers et seconds moyens de tranchage 20 et 30 sont courbes, parallèles entre elles et équidistantes les unes des autres. Les premiers et seconds moyens de tranchage 20 et 30 se présentent sous la forme d'un quart de disque, comme sur les figures 1 à 5, leur périphérie affleurant la surface interne 11 de la cuve 10 lors d'une opération de tranchage de caillé. Le centre du rayon de courbure des lames courbes 23' des premiers moyens de tranchage 20 est situé sensiblement au point de rencontre de la tige de support 16 et du rebord 13 de la cuve 10, c'est-à-dire au niveau de la partie d'extrémité 16a de la tige support 16.Figures 8 to 10 illustrate a third embodiment of the sliced curd production device 1 according to the present invention. In this variant, all the blades 23 'and 33' respectively belonging to the first and second slicing means 20 and 30 are curved, parallel to each other and equidistant from each other. The first and second slicing means 20 and 30 are in the form of a quarter disc, as in Figures 1 to 5, their periphery flush with the inner surface 11 of the vessel 10 during a slicing operation of curd . The center of the radius of curvature of the curved blades 23 'of the first slicing means 20 is located substantially at the meeting point of the support rod 16 and the rim 13 of the tank 10, that is to say at the level of the end portion 16a of the support rod 16.
Le centre du rayon de courbure des lames courbes 33' des seconds moyens de tranchage 30 est situé sensiblement au point de rencontre de l'axe de pivotement 31 et de la tige de support 16, c'est-à-dire au milieu 16c de cette dernière. Dans cette configuration, la lame 33' la plus longue, c'est-à-dire la lame la plus éloignée du milieu 16c de la tige de support 16, affleure la surface interne hémisphérique 11 de la cuve 11 lors d'une opération de tranchage de caillé, comme cela ressort clairement des figures 8 et 10. La figure 11 illustre un quatrième mode de réalisation du dispositif de production de caillé tranché 1 conforme à la présente invention.The center of the radius of curvature of the curved blades 33 'of the second slicing means 30 is located substantially at the meeting point of the pivot axis 31 and the support rod 16, that is to say at the middle 16c of the latter. In this configuration, the longest blade 33 ', that is to say the blade farthest from the middle 16c of the support rod 16, is flush with the hemispherical inner surface 11 of the vessel 11 during a slicing of curd, as is evident from FIGS. 8 and 10. FIG. 11 illustrates a fourth embodiment of sliced curd production device 1 according to the present invention.
Dans ce mode de réalisation, les lames courbes 23' des premiers moyens de tranchage 20 sont portées par une barre 26 s' étendant parallèlement à la tige de support 16 et maintenue à distance de celle-ci par des entretoises de liaison 25. La barre 26 présente une longueur sensiblement égale au diamètre de la cuve 10. La longueur respective des lames courbes 23' est telle que l'extrémité libre 23a de chacune d'elles affleure la surface interne hémisphérique 11 de la cuve 10. Dans cette configuration, les premiers moyens de tranchage 20 forment un demi-disque plan dont la périphérie affleure la surface interne 11 lorsqu'ils sont introduits dans la cuve 10, en particulier lors d'une opération de tranchage de caillé. Les seconds moyens de tranchage 30 sont quant à eux identiques à ceux des figure 1 à 7, c'est-à-dire en forme de quart de disque et avec des lames droites équidistantes 32.In this embodiment, the curved blades 23 'of the first slicing means 20 are carried by a bar 26 extending parallel to the support rod 16 and kept at a distance from the latter by connecting struts 25. The bar 26 has a length substantially equal to the diameter of the tank 10. The respective length of the curved blades 23 'is such that the free end 23a of each of them is flush with the hemispherical inner surface 11 of the tank 10. In this configuration, the first slicing means 20 form a half-disk plane whose periphery is flush with the inner surface 11 when introduced into the tank 10, in particular during a slicing operation of curd. The second slicing means 30 are in turn identical to those of FIGS. 1 to 7, that is to say in the form of a quarter disc and with equidistant straight blades 32.
Selon des variantes de ce mode de réalisation qui ne sont pas représentées, les seconds moyens de tranchage 30 peuvent être identiques à ceux des figures 8 à 10 (forme en quart de disque et lames courbes) , ou bien identiques aux premiers moyens de tranchage 20 des figure 6 et 7 (forme en demi-disque et lames droites) , ou encore identiques aux premiers moyens de tranchage 20 de la figure 11 (forme en demi-disque et lames courbes) .According to variants of this embodiment which are not shown, the second slicing means 30 may be identical to those of FIGS. 8 to 10 (quarter disc shape and curved blades), or else identical to the first slicing means 20 of FIGS. 6 and 7 (half-disk shape and straight blades), or else identical to the first slicing means 20 of FIG. 11 (half-disk shape and curved blades).
Le fonctionnement du dispositif de tranchage 1 conforme à la présente l'invention va maintenant être décrit plus spécifiquement en relation avec le mode de réalisation des figures 1 à 5.The operation of the slicing device 1 according to the present invention will now be described more specifically in connection with the embodiment of Figures 1 to 5.
Le caillé étant formé dans la cuve 10, les moyens de tranchage 20 et 30 sont introduits à l'intérieur de celle-ci par pivotement de l'anneau rotatif 15 sur son articulation suivant la flèche P2. Pour cette opération délicate, il convient de faire attention à ce que les seconds moyens de tranchage 30 restent entièrement hors de la cuve 10 et que les premiers moyens de tranchage 20 pénètrent dans le caillé perpendiculairement à la surface de celui-ci de manière à l'abîmer le moins possible. Les premiers moyens de tranchage 20 sont amenés à pivoter selon la direction de tranchage Fl par l'entraînement en rotation de l'anneau sur son axe de révolution XX' dans un sens ou dans l'autre selon la flèche Rl. Cette rotation peut par exemple être de quelques degrés à plusieurs dizaines de degrés. Dans le cas présent, la rotation est de 90° dans le sens des aiguilles d'une montre de sorte qu'un quart du caillé contenu dans la cuve 10 est découpé sous la forme de tranches horizontales formant des quarts de disques superposés. En effet, les deux côtés tranchants des lames 23 sont disposés parallèlement à la tige de support 16, c'est-à-dire selon la direction de tranchage Fl et sa direction inverse.The curd being formed in the tank 10, the slicing means 20 and 30 are introduced inside thereof by pivoting the rotary ring 15 on its articulation along the arrow P2. For this delicate operation, it should be noted that the second slicing means 30 remain entirely out of the tank 10 and that the first slicing means 20 penetrate the curd perpendicular to the surface thereof so as to damage as little as possible. The first slicing means 20 are pivoted in the slicing direction F1 by the rotational drive of the ring on its axis of revolution XX 'in one direction or the other along the arrow R1. This rotation may for example be from a few degrees to several tens of degrees. In the present case, the rotation is 90 ° in the direction of clockwise so that a quarter of the curd contained in the tank 10 is cut in the form of horizontal slices forming quarter of superimposed disks. Indeed, the two cutting edges of the blades 23 are arranged parallel to the support rod 16, that is to say in the cutting direction Fl and its reverse direction.
Ensuite, les seconds moyens de tranchage 30 affleurant la surface du caillé, ces derniers sont amenés à pivoter selon la seconde direction de tranchage F2 par entraînement en rotation de la manivelle dans un sens ou dans l'autre selon la flèche Rl. Cette rotation est effectuée sur un peu plus de 180° de sorte qu'une moitié du caillé contenu dans la cuve 10 est découpée sous forme de tranches verticales parallèles entre elles. En effet, les deux côtés tranchants des lames 33 sont disposés parallèlement à la tige de support 16, c'est-à-dire selon la direction de tranchage F2 et sa direction inverse. En particulier, le quart du caillé déjà tranché horizontalement par les premiers moyens de tranchage 20 lors de l'opération précédente est également découpé verticalement, de manière à former de petits morceaux homogènes de caillé en forme de « nouilles » droites parallèles.Then, the second slicing means 30 flush with the surface of the curd, the latter are rotated in the second slicing direction F2 by rotating the crank in one direction or the other along the arrow Rl. This rotation is performed on a little more than 180 ° so that half of the curd contained in the tank 10 is cut in the form of vertical slices parallel to each other. Indeed, the two cutting edges of the blades 33 are arranged parallel to the support rod 16, that is to say in the slicing direction F2 and its reverse direction. In particular, the quarter of the curd already sliced horizontally by the first slicing means 20 during the previous operation is also cut vertically, so as to form small homogeneous pieces of curd in the form of "noodles" parallel straight.
Une fois les seconds moyens de tranchage 30 hors de la cuve (comme illustré sur la figure 1 par exemple), c'est-à-dire après un pivotement de plus de 180°, les premiers moyens de tranchage 20 sont de nouveau amenés à pivoter sur 90° selon la première direction de tranchage Fl. Dans ce cas, un autre quart du caillé est tranché horizontalement . Les seconds moyens de tranchage sont de nouveau introduits dans le caillé et amenés à pivoter de 180° à l'aide de la manivelle 37, de sorte que des tranches verticales sont découpées dans le caillé, et notamment dans les deux premiers quarts de caillé tranché horizontalement par les premiers moyens de tranchage 20. En effectuant quatre fois de suite cette alternance de pivotements des premiers moyens de tranchage 20 sur 90° puis des seconds moyens de tranchage 30 sur 180° jusqu'à ce que les premiers moyens de tranchage 20 aient parcouru un tour complet dans la cuve 10, on aboutit à un caillé découpé de façon très homogène en petits morceaux ayant chacun sensiblement la forme d'un cube. Le caillé ainsi tranché est donc prêt à perdre son sérum de façon optimale.Once the second slicing means 30 out of the tank (as illustrated in Figure 1 for example), that is to say after a pivoting of more than 180 °, the first slicing means 20 are again brought to rotate 90 ° in the first slicing direction Fl. In this case, another quarter of the curd is sliced horizontally. The second slicing means are again introduced into the curd and rotated by 180 ° using the crank 37, so that vertical slices are cut in the curd, and in particular in the first two quarters of sliced curd horizontally by the first slicing means 20. Performing four times in succession this alternation of pivoting of the first slicing means 20 to 90 ° and second slicing means 30 over 180 ° until the first slicing means 20 have After one complete revolution in the vat 10, the result is a curd cut very homogeneously into small pieces each having substantially the shape of a cube. The curd thus sliced is ready to lose its serum optimally.
Afin d'éviter que le caillé se déplace en rotation selon la première direction de tranchage Fl lors du pivotement des premiers moyens de tranchage 20 dans la cuve 10, il est prévu de placer des moyens anti-rotation 40. Ces moyens 40 sont constitués par une plaque mince pleine 42 en forme de quart de disque. La plaque 42 est introduite verticalement à l'intérieur du caillé préalablement à l'opération de tranchage, à proximité immédiate des premiers moyens de tranchage 20, comme illustrée sur les figures 12 et 13. Ainsi, lors de la rotation des premiers moyens de tranchage 20 selon la première direction de tranchage Fl, le caillé, poussé par les organes de découpage 22, est bloqué par la plaque 42. Ceci permet ainsi de garantir un tranchage optimisé et une excellente homogénéité en ce qui concerne la dimension des morceaux obtenus . La plaque 42 est de préférence extraite verticalement lentement et délicatement du caillé juste avant que les premiers moyens de tranchage 20 aient terminé leur tour complet à l'intérieur de la cuve 10.In order to prevent the curd from rotating in the first direction of slicing Fl when the first slicing means 20 are pivoted in the tank 10, it is intended to place anti-rotation means 40. These means 40 consist of a solid thin plate 42 in the form of a quarter disc. The plate 42 is introduced vertically inside the curd prior to the slicing operation, in the immediate vicinity of the first slicing means 20, as illustrated in Figures 12 and 13. Thus, during the rotation of the first slicing means 20 in the first cutting direction F1, the curd, pushed by the cutting members 22, is blocked by the plate 42. This thus makes it possible to ensure optimized slicing and excellent homogeneity as regards the size of the pieces obtained. The plate 42 is preferably extracted vertically slowly and delicately from the curd just before the first means of slicing 20 have completed their complete turn inside the tank 10.
