MOULE A FROMAGES, DISPOSITIF DE SOUDURE AUX ULTRASONS
POUR LA FABRICATION DE CE MOULE ET PROCEDE DE FABRICATION
DE FROMAGES
La présente invention se rapporte principalement à un moule à fromages, à un dispositif de soudure aux ultrasons, notamment à une sonotrode ou à un réflecteur des ultrasons particulièrement bien adapté à la fabrication de ce moule et à un procédé de fabrication de fromages mettant en oeuvre un tel moule.CHEESE MOLD, ULTRASONIC WELDING DEVICE
FOR THE MANUFACTURE OF THIS MOLD AND METHOD OF MANUFACTURE
CHEESES
The present invention relates mainly to a cheese mold, to an ultrasonic welding device, in particular to a sonotrode or to an ultrasonic reflector particularly well suited to the manufacture of this mold and to a process for manufacturing cheeses using such a mold.
II est bien connu de fabriquer des fromages en égouttant des caillés dans des moules. Avec des moules cylindriques à parois lisses, cette opération est longue, de l'ordre de 23 heures, et l'on n'arrive pas à contrôler l'état de surface du fromage. It is well known to make cheeses by draining curds in molds. With cylindrical molds with smooth walls, this operation is long, of the order of 23 hours, and it is not possible to control the surface condition of the cheese.
La Demanderesse a été amenée à effectuer des essais avec des moules perforés qui, également, n'ont pas donné satisfaction, car même si l'on obtenait une faible accélération de l'égouttage, la qualité du fromage égoutté était compromise par un marquage mécanique des talons et l'apparition de moisissures locales. De même, des essais effectués avec des moules en matière plastique moulés comportant sur leurs parois intemes des micro-perforations et/ou des reliefs, notamment quadrillés, se sont révélés insuffisants pour assurer un morgeage et un égouttage efficace du fromage. The Applicant has been led to carry out tests with perforated molds which, also, were not satisfactory, because even if a slow acceleration of the drainage was obtained, the quality of the drained cheese was compromised by mechanical marking. heels and the appearance of local mold. Likewise, tests carried out with molds made of molded plastic material comprising on their inner walls micro-perforations and / or reliefs, in particular checkered, have been found to be insufficient to ensure effective chewing and draining of the cheese.
II est connu, d'autre part, pour des fromages de type reblochon, de mettre en oeuvre des moules munis d'une rehausse assurant la fixation d'une toile souple. It is known, on the other hand, for cheeses of the Reblochon type, to use molds provided with an extension ensuring the fixing of a flexible canvas.
C'est un but de la présente invention d'offrir un moule à fromages assurant un égouttage rapide et efficace. It is an object of the present invention to provide a cheese mold ensuring rapid and effective drainage.
C'est également un but de la présente invention d'offrir un moule permettant de contrôler l'état de la surface du fromage, et notamment la formation de la morge, tout en évitant les moisissures locales et/ou le poissage local. It is also an object of the present invention to provide a mold for controlling the condition of the surface of the cheese, and in particular the formation of the snout, while avoiding local mold and / or local sticking.
C'est aussi un but de la présente invention d'offrir un moule à fromages permettant le retournement du fromage, notamment au cours de l'égouttage. It is also an object of the present invention to provide a cheese mold allowing the cheese to be turned over, in particular during draining.
C'est également un but de la présente invention d'offrir un moule à fromages permettant le démoulage par vibrations. It is also an object of the present invention to provide a cheese mold allowing demoulding by vibration.
C'est aussi un but de la présente invention d'offrir un moule à fromages dont le nettoyage est aisé et efficace. It is also an object of the present invention to provide a cheese mold whose cleaning is easy and effective.
C'est également un but de la présente invention d'offrir un moule à fromages dont les manipulations sont aisées, notamment un moule monobloc. It is also an object of the present invention to provide a cheese mold whose handling is easy, in particular a monobloc mold.
C'est aussi un but de la présente invention d'offrir un moule à fromages évitant le marquage des talons de fromages. It is also an object of the present invention to provide a cheese mold avoiding the marking of the heels of cheese.
C'est également un but de la présente invention d'offrir un moule à fromages stable et durable. It is also an object of the present invention to provide a stable and durable cheese mold.
Ces buts sont atteints par un moule à fromages dont les parois, notamment celles qui sont verticales en condition d'utilisation lors de l'égouttage du fromage, sont munies d'un store comportant des mailles d'évacuation d'eau. Le store est solidarisé avec les parois du moule, par exemple par soudure aux ultrasons. These aims are achieved by a cheese mold, the walls of which, in particular those which are vertical under conditions of use when the cheese is draining, are provided with a blind comprising water drainage meshes. The blind is secured to the walls of the mold, for example by ultrasonic welding.

L'invention sera mieux comprise au moyen de la description ci-après et des figures annexées données comme des exemples non limitatifs, et sur lesquelles:
- la figure 1 est une vue de dessus d'un premier exemple de réalisation du moule selon la présente invention
- la figure 2 est une vue en perspective du moule de la figure 1;

- la figure 6 est une vue de dessus du dispositif de réflexion d'ultrasons de la figure 5;
- la figure 7 est une vue de face du dispositif de réflexion d'ultrasons de la figure 5.The invention will be better understood by means of the description below and the appended figures given as nonlimiting examples, and in which:

- Figure 2 is a perspective view of the mold of Figure 1;

Sur les figures 1 à 7, I'on a utilisé les mêmes références pour désigner les mêmes éléments. In FIGS. 1 to 7, the same references have been used to designate the same elements.
Sur les figures 1 à 4, I'on peut voir un moule selon la présente invention pour fromages à pâte molle. De manière classique, ce type de fromage est obtenu par l'égouttage dans des moules d'un caillé. Durant l'égouttage, le fromage est retourné plusieurs fois. Typiquement, I'on utilise des moules sans fond disposés sur un plateau d'égouttage. Lors de l'opération de retournement, I'on place un second plateau d'égouttage sur tous les moules du plateau et l'on retourne l'ensemble constitué par les moules pris en sandwich entre les deux plateaux d'égouttage. Le plateau d'égouttage supérieur est retiré jusqu'au prochain retournement. II est important, lors des opérations de retournement, d'éviter d'abîmer le fromage. Un défaut classique, couramment appelé défaut en casquette, peut être provoqué par l'accrochage du fromage sur le moule. II est donc important d'obtenir un moule dont les parois sont suffisamment lisses pour ne pas favoriser la déformation des fromages en casquette. In Figures 1 to 4, we can see a mold according to the present invention for soft cheeses. Conventionally, this type of cheese is obtained by draining in molds of a curd. During draining, the cheese is turned over several times. Typically, bottomless molds are used which are placed on a drip tray. During the inversion operation, a second drip tray is placed on all the molds on the tray and the assembly consisting of the molds sandwiched between the two drip trays is turned over. The upper drip tray is removed until the next turnaround. It is important, during turning operations, to avoid damaging the cheese. A classic defect, commonly called a cap defect, can be caused by the cheese sticking to the mold. It is therefore important to obtain a mold whose walls are sufficiently smooth so as not to favor the deformation of the cheeses in a cap.
Le moule 1 selon la présente invention comporte avantageusement une paroi cylindrique 2 réalisée typiquement en matière plastique, notamment en polypropylène sur laquelle est fixé en 3 un store 4 comprenant des mailles facilitant l'égouttage du caillé. II est bien entendu que d'autres formes de parois, et notamment un moule ovale, elliptique ou polygonal, notamment triangulaire, carré, rectangulaire, pentagonal, hexagonal ou autres ne sortent pas du cadre de la présente invention. De même, I'invention n'est pas limitée à des moules comportant des parois verticales. Notamment, les moules à parois en pentes (négatives ou positives), comme par exemple les moules coniques, tronconiques, pyramidaux ou prismatiques, ne sortent pas du cadre de la présente invention. The mold 1 according to the present invention advantageously comprises a cylindrical wall 2 typically made of plastic, in particular polypropylene on which is fixed at 3 a blind 4 comprising meshes facilitating the drainage of the curd. It is understood that other forms of walls, and in particular an oval, elliptical or polygonal, in particular triangular, square, rectangular, pentagonal, hexagonal or other mold, do not depart from the scope of the present invention. Likewise, the invention is not limited to molds having vertical walls. In particular, molds with sloping walls (negative or positive), such as for example conical, frustoconical, pyramidal or prismatic molds, do not depart from the scope of the present invention.
Le store 4 est avantageusement un store rigide, réalisé également en polypropylène ayant le même dessin que le store d'affinage. Un exemple de réalisation particulièrement performant du moule selon la présente invention comporte un store 4 quadrillé vendu par la Société
NORTEN sous la référence 5230. Avantageusement, les mailles du store 4 quadrillé sont inclinées symétriquement par rapport à la verticale dans la condition d'égouttage. Par exemple, un store 4 quadrillé dont les mailles se croisent à angle droit, est disposé sur la paroi 2 de manière à ce que les mailles forment un angle de 45 avec la verticale.The blind 4 is advantageously a rigid blind, also made of polypropylene having the same design as the refinement blind. An example of a particularly efficient embodiment of the mold according to the present invention comprises a grid 4 blind sold by the Company
NORTEN under the reference 5230. Advantageously, the meshes of the grid 4 blind are inclined symmetrically relative to the vertical in the draining condition. For example, a grid blind 4 whose meshes intersect at right angles is placed on the wall 2 so that the meshes form an angle of 45 with the vertical.
D'une manière générale, I'on peut faire varier trois paramètres principaux de la structure du moule selon l'invention pour obtenir l'égouttage désiré:
a) le diamètre des fils du store,
b) la distance entre les fils consécutifs,
c) I'orientation du maillage.In general, we can vary three main parameters of the structure of the mold according to the invention to obtain the desired drainage:
a) the diameter of the blind wires,
b) the distance between the consecutive wires,
c) the orientation of the mesh.
Une augmentation du diamètre des fils et surtout de la distance entre les fils consécutifs accélère l'égouttage et procure un marquage plus important du fromage. An increase in the diameter of the strands and especially in the distance between the consecutive strands accelerates the draining and provides greater marking of the cheese.
Les fils de faible diamètre avec une faible distance entre les mailles du store procurent une croûte fine au prix d'un égouttage plus long. The small diameter wires with a small distance between the mesh of the blind provide a fine crust at the cost of longer draining.
Des mailles présentant une pente importante, avec des parois du moule avantageusement verticales, accélèrent également l'égouttage. Meshes with a significant slope, with advantageously vertical mold walls, also accelerate the drainage.
Dans l'exemple préféré illustré sur les figures, les fixations 3 du store 4 sur la paroi 2 du moule 1 forment deux génératrices du cylindre diamétralement opposées. Avantageusement, le moule selon l'invention comporte des moyens de positionnement du store sur sa paroi interne avant la soudure. Les moyens de positionnement 3' comportent, par exemple, une saillie radiale s'étendant sur toute la hauteur de la paroi du moule parallèlement à une génératrice du cylindre et dont l'épaisseur est sensiblement égale à l'épaisseur du store. Lors de la soudure aux ultrasons du store sur le moule, la saillie constitue un apport de matières améliorant la fixation du store sur le moule. La soudure aux ultrasons du store sur la face interne du moule est nettement améliorée par la mise en oeuvre d'une tête de soudure appelée sonotrode et/ou d'un réflecteur d'ultrasons appelé enclume selon la présente invention comportant des rainures de réception des fils du store. Pour la soudure d'éléments épais et/ou en grande série, il peut être avantageux de fabriquer une sonotrode spécifique. Pour la soudure de petites séries d'éléments de faible épaisseur, il est avantageux de mettre en oeuvre une enclume, comme par exemple celle illustrée sur les figures 5 et 6. Une enclume 6 ou sonotrode selon la présente invention comporte une surface 7 de réflexion ou d'émission conforme à la surface de réception constituée par la paroi interne du moule (toutefois sans tenir compte d'une éventuelle saillie formant les moyens de positionnement du store lors de la soudure), muni du store. Ainsi, la surface 7 de réflexion ou d'émission reprend la courbure générale (éventuelle) de la surface inteme du moule. Sur cette surface 7 de réflexion ou d'émission, I'on a avantageusement ménagé des rainures de réception de fils ou des mailles du store qui ainsi adhèrent mieux, après la soudure, à la surface interne du moule. Dans le premier exemple de réalisation, L'enclume ou la sonotrode est sensiblement rectiligne permettant de réaliser la soudure droite 3 illustrée sur les figures 1 et 2. In the preferred example illustrated in the figures, the fasteners 3 of the blind 4 on the wall 2 of the mold 1 form two generatrices of the diametrically opposite cylinder. Advantageously, the mold according to the invention comprises means for positioning the blind on its internal wall before welding. The positioning means 3 'include, for example, a radial projection extending over the entire height of the mold wall parallel to a generator of the cylinder and the thickness of which is substantially equal to the thickness of the blind. During the ultrasonic welding of the blind on the mold, the projection constitutes a supply of materials improving the fixing of the blind on the mold. The ultrasonic welding of the blind on the internal face of the mold is significantly improved by the use of a welding head called a sonotrode and / or an ultrasonic reflector called an anvil according to the present invention comprising grooves for receiving the son of the blind. For the welding of thick elements and / or in large series, it may be advantageous to manufacture a specific sonotrode. For the welding of small series of thin elements, it is advantageous to use an anvil, such as for example that illustrated in FIGS. 5 and 6. An anvil 6 or sonotrode according to the present invention comprises a reflection surface 7 or emission in accordance with the receiving surface formed by the internal wall of the mold (however without taking account of a possible projection forming the means for positioning the blind during welding), provided with the blind. Thus, the surface 7 of reflection or emission takes up the general curvature (if any) of the internal surface of the mold. Advantageously, on this reflection or emission surface 7, grooves for receiving wires or stitches for the blind have been formed, which thus adhere better, after welding, to the internal surface of the mold. In the first exemplary embodiment, the anvil or the horn is substantially rectilinear making it possible to produce the straight weld 3 illustrated in FIGS. 1 and 2.
Avantageusement, la surface 7 de réflexion ou d'émission comporte à ses extrémités des zones 8 de plus grande largeur permettant de réaliser des soudures 3 illustrées sur les figures 3 et 4. Ce type de soudure est avantageux car les branches horizontales 9 du I qui affleurent le fond et l'extrémité supérieure du moule résistent mieux aux contraintes importantes subies notamment lors du raclage avec un répartiteur durant le remplissage avec un caillé. Un exemple avantageux d'enclume 6 selon l'invention illustrée sur les figures 5 à 7 comporte des moyens de positionnement des moules. Advantageously, the reflection or emission surface 7 has at its ends zones 8 of greater width making it possible to produce welds 3 illustrated in FIGS. 3 and 4. This type of welding is advantageous since the horizontal branches 9 of I which are flush with the bottom and the upper end of the mold are more resistant to the significant stresses undergone, in particular during scraping with a distributor during filling with a curd. An advantageous example of anvil 6 according to the invention illustrated in FIGS. 5 to 7 comprises means for positioning the molds.
Une butée 10 reçoit la base du moule au niveau de la soudure à effectuer, la base du côté diamétralement opposé du moule reposant sur un fond 11 d'une gorge en U 12. Des moyens 13 de guidage angulaires permettent avantageusement de bloquer en rotation le moule dans la position de soudure, par exemple en maintenant des entretoises 14 situées sur la surface externe du moule.A stop 10 receives the base of the mold at the weld to be made, the base on the diametrically opposite side of the mold resting on a bottom 11 of a U-shaped groove 12. Angular guide means 13 advantageously make it possible to block in rotation the mold in the welded position, for example by maintaining spacers 14 located on the external surface of the mold.
La soudure du store sur le moule comporte les étapes consistant à:
- disposer un moule muni du store à sondes sur l'enclume 6, la saillie radiale correspondant à l'endroit de la soudure disposée face à la surface de réflexion 7;
- disposer la sonotrode sur la face externe du moule en vis à vis de la surface de réflexion 7;
- émettre les ultrasons nécessaires à la réalisation de la soudure.Welding the blind on the mold includes the steps of:
- have a mold provided with the probe blind on the anvil 6, the radial projection corresponding to the location of the weld disposed facing the reflection surface 7;
- arrange the sonotrode on the external face of the mold opposite the reflection surface 7;
- emit the ultrasound necessary for carrying out the weld.
L'opération est répétée pour toutes les soudures nécessaires pour la réalisation du moule. The operation is repeated for all the welds necessary for the production of the mold.
Avantageusement, pour accélérer l'égouttage, la paroi 2 du moule 1 comporte des ouvertures traversantes 5. Advantageously, to speed up the draining, the wall 2 of the mold 1 has through openings 5.
Avantageusement, la paroi 2 du moule 1 a une épaisseur El comprise entre 2 et 6 mm, de préférence entre 2,5 et 5 mm, par exemple égale à 3. L'épaisseur E2 du store 4 est, par exemple, comprise entre 0,5 et 2,5 mm, de préférence entre 1 et 2 mm, par exemple égale à 1,3 mm. Advantageously, the wall 2 of the mold 1 has a thickness E1 between 2 and 6 mm, preferably between 2.5 and 5 mm, for example equal to 3. The thickness E2 of the blind 4 is, for example, between 0 , 5 and 2.5 mm, preferably between 1 and 2 mm, for example equal to 1.3 mm.
Un espace, par exemple égal à 0,5 mm, peut être ménagé entre le store 4 et la face interne de la paroi cylindrique 2. Le moule selon la présente invention a permis d'améliorer, de façon spectaculaire, l'égouttage du fromage dont la durée a été ramenée de 23 heures, pour un moule dépourvu de store 4, à une durée de 8 heures, avec quatre retournements pendant l'égouttage. De plus, la présence du store 4 a permis d'éviter le marquage des talons du fromage par les ouvertures 5. Avec le moule selon la présente invention, I'on a obtenu une croûte lisse avec un morgeage suffisant tout en évitant le poissage. La présence du store 4 ne provoque pas d'augmentation du taux de déformation en casquette lors du retournement des moules pendant l'opération d'égouttage des fromages. A space, for example equal to 0.5 mm, can be provided between the blind 4 and the internal face of the cylindrical wall 2. The mold according to the present invention has made it possible to dramatically improve the drainage of the cheese. the duration of which has been reduced from 23 hours, for a mold without blind 4, to a duration of 8 hours, with four turnings during draining. In addition, the presence of the blind 4 made it possible to avoid the marking of the heels of the cheese by the openings 5. With the mold according to the present invention, a smooth crust was obtained with sufficient mold while avoiding sticking. The presence of the blind 4 does not increase the rate of deformation in the cap when the molds are turned over during the cheese draining operation.
Avec les moules selon la présente invention, I'on peut utiliser les moyens de démoulage par vibration. With the molds according to the present invention, it is possible to use the demolding means by vibration.
Le choix du store 4 sera guidé par la rapidité de l'égouttage désiré et par d'éventuels motifs à appliquer sur les talons du fromage. Ainsi, la mise en oeuvre d'un store comportant des mailles linéaires, par exemple verticaux, ne sort pas du cadre de la présente invention. De même, la mise en oeuvre d'autres moyens de fixation de stores sur la paroi 2 ne sort pas du cadre de la présente invention. The choice of blind 4 will be guided by the speed of the desired draining and by possible patterns to be applied on the heels of the cheese. Thus, the implementation of a blind comprising linear meshes, for example vertical, does not depart from the scope of the present invention. Similarly, the implementation of other means for fixing blinds to the wall 2 does not depart from the scope of the present invention.
La mise en oeuvre d'un moule monobloc avec un store indissociable facilite les manipulations lors de l'égouttage, ainsi que lors du nettoyage des moules. Le moule monobloc est extrêmement hygiénique permettant un nettoyage complet après démoulage des fromages. The implementation of a one-piece mold with an inseparable blind facilitates handling during draining, as well as during cleaning of the molds. The monobloc mold is extremely hygienic allowing a complete cleaning after unmolding the cheeses.
De plus, il peut s'avérer avantageux de mettre en oeuvre un ensemble monobloc de moules selon l'invention juxtaposés et solidarisés. Par exemple, I'on assure l'injection d'une pièce en matière plastique formant une pluralité de moules. Les moules individuels ou les pluralités des moules obtenus par injections peuvent être assemblés par collage ou avantageusement par soudure, notamment par soudure aux ultrasons. In addition, it may prove advantageous to use a one-piece assembly of molds according to the invention juxtaposed and secured. For example, we provide injection of a plastic part forming a plurality of molds. The individual molds or the plurality of molds obtained by injections can be assembled by gluing or advantageously by welding, in particular by ultrasonic welding.
Avantageusement, les moules selon la présente invention sont munis d'entretoises, par exemple en forme de parallélépipède rectangle s'étendant, pour les moules cylindriques, parallèlement à une génératrice du cylindre. La solidarisation des moules est avantageusement obtenue par soudure des entretoises.Advantageously, the molds according to the present invention are provided with spacers, for example in the shape of a rectangular parallelepiped extending, for cylindrical molds, parallel to a generator of the cylinder. The joining of the molds is advantageously obtained by welding the spacers.
L'invention s'applique principalement à la fabrication des fromages. The invention mainly applies to the manufacture of cheeses.
