Abstract

Hot or cold cured elastomers made of silicones are compression moulded to make flexible moulds, of mean thickness 1.5-2mm, for the food industry particularly for the cooking or setting of foods.

Description

La présente invention se rapporte à des moules flexibles à base de silicones destinés à l'industrie alimentaire et notamment à la pâtisserie (moule à génoise, moule à cake, moule à brioches, à savarins, à madeleines, à financiers, etc.). The present invention relates to flexible molds based on silicones intended for the food industry and in particular for pastry making (sponge mold, cake mold, brioche, savarin, madeleine, financier mold, etc.).

Les moules du type susmentionné ont, pendant longtemps, été fabriqués en métal (acier ou aluminium) l'application d'une pellicule de corps gras (huile ou beurre) sur leurs parois internes n'empêchait pas leurs utilisateurs de se heurter, lors du démoulage, à des problèmes d'adhérence et de collage nuisant notablement à l'aspect du produit final. The molds of the aforementioned type have, for a long time, been made of metal (steel or aluminum) the application of a film of fatty substance (oil or butter) on their internal walls did not prevent their users from colliding when demoulding, adhesion and sticking problems significantly affecting the appearance of the final product.

En outre, le nettoyage des moules ainsi souillés était toujours long et incommode et nécessitait fréquemment des opérations de grattage favorisant le collage et aboutissant à la longue à un endommagement du moule et donc à une diminution de sa durée de vie. In addition, cleaning the molds thus soiled was always long and inconvenient and frequently required scraping operations favoring sticking and leading in the long run to damage to the mold and therefore to a decrease in its life.

Pour résoudre ces problèmes, il a été proposé d'appliquer sur les parois internes des moules métalliques des revêtements anti-adhérents en particulier en polytétrafluoréthylène ; malgré ses avantages certains, une telle application ne s'est pas avérée totalement satisfaisante, en particulier en raison de la fragilité des revêtements anti-adhérents et de leur grande sensibilité à l'abrasion dont la conséquence est qu'ils deviennent très rapidement inutilisables. To solve these problems, it has been proposed to apply non-stick coatings, in particular polytetrafluoroethylene, to the internal walls of metal molds; in spite of its certain advantages, such an application has not proved completely satisfactory, in particular because of the fragility of the non-stick coatings and their great sensitivity to abrasion, the consequence of which is that they become unusable very quickly.

De plus, la mise en oeuvre de ces revêtements antiadhérents ne permet pas de résoudre tous les problèmes rencontrés par les utilisateurs lors du démoulage, compte tenu de la rigidité des moules métalliques : il est, en effet, souvent nécessaire, pour extraire le produit cuit, de donner des coups sur le fond ou les parois latérales du moule, voire de passer la lame d'un couteau entre ce dernier et le produit. In addition, the use of these non-stick coatings does not solve all the problems encountered by users during demolding, given the rigidity of metal molds: it is, in fact, often necessary, to extract the cooked product , to strike the bottom or the side walls of the mold, or even to pass the blade of a knife between the latter and the product.

Pour remédier aux inconvénients susmentionnés, on a par ailleurs déjà proposé, conformément au document FR-A86 02 471, un ensemble destiné à la cuisson d'aliments et se composant d'un plateau en acier inoxydable ou en aluminium portant une membrane anti-adhérente préformée constituée par une trame de fils ou fibres de verre, de carbone ou de céramique imprégnée ou enduite d'un matériau anti-adhérent, en particulier de résine de silicones. To overcome the aforementioned drawbacks, there has already been proposed, in accordance with document FR-A86 02 471, an assembly intended for cooking food and consisting of a tray of stainless steel or aluminum carrying a non-stick membrane. preformed formed by a weft of son or fibers of glass, carbon or ceramic impregnated or coated with a non-stick material, in particular silicone resin.

On a également proposé, conformément au document
FR-A-90 01 561, une membrane destinée à la surgélation et/ou à la cuisson de produits alimentaires et constituée d'une trame tricotée en fils de verre ou de céramique comportant au moins deux revêtements en silicones, à savoir un premier revêtement effectué avec un silicone assurant la rigidité du matériau de manière à ce qu'il soit autoportant et un second revêtement réalisé avec un silicone souple à très forte anti-adhérence, de préférence avec un très fort coefficient d'allongement.It was also proposed, in accordance with the document
FR-A-90 01 561, a membrane intended for deep-freezing and / or cooking of food products and consisting of a knitted weft of glass or ceramic threads comprising at least two silicone coatings, namely a first coating made with a silicone ensuring the rigidity of the material so that it is self-supporting and a second coating made with a flexible silicone with very high anti-adhesion, preferably with a very high coefficient of elongation.

En plus de leur caractère anti-adhérent, les moules décrits dans ces deux publications présentent l'avantage d'être flexibles, et de pouvoir se déformer lors du démoulage, ce qui facilite largement cette opération ; leur configuration particulière et leur caractère composite les rendent cependant particulièrement onéreux et ne leur permettent, en outre, pas de s'adapter à toutes les géométries et notamment aux formes comportant des angles droits. In addition to their non-stick nature, the molds described in these two publications have the advantage of being flexible, and of being able to deform during demolding, which greatly facilitates this operation; their particular configuration and their composite character make them however particularly expensive and do not allow them, moreover, not to adapt to all the geometries and in particular to the shapes comprising right angles.

La présente invention permet de remédier à ces inconvénients grâce à l'utilisation d'élastomères vulcanisant à chaud ou à froid et constitués par des silicones pour la fabrication, par moulage par compression, de moules flexibles destinés à l'industrie alimentaire et en particulier à la cuisson ou à la congélation d'aliments. The present invention overcomes these drawbacks through the use of elastomers vulcanizing hot or cold and consisting of silicones for the manufacture, by compression molding, of flexible molds intended for the food industry and in particular for cooking or freezing food.

Les silicones pouvant être utilisés conformément à l'invention doivent, bien entendu, être alimentaires ; ils peuvent se présenter sous forme d'huiles réactives (élastomères vulcanisant à froid - EVF), en particulier de produits de type
RTV (Room Temperature Vulcanizing) ou encore de gommes (élastomères vulcanisant à chaud - EVC).The silicones which can be used in accordance with the invention must, of course, be edible; they can be in the form of reactive oils (cold vulcanizing elastomers - EVF), in particular of the type
RTV (Room Temperature Vulcanizing) or gums (hot vulcanizing elastomers - EVC).

Compte tenu de leur plus faible prix, on utilise de préférence des EVC et en particulier des polyméthylsiloxanes de haut poids moléculaire vulcanisant à environ 150 à 1600C. Given their lower price, EVCs are used, and in particular high molecular weight polymethylsiloxanes vulcanizing at around 150 to 1600C.

A titre d'exemple, on peut avantageusement mettre en oeuvre le produit commercialisé par la Société RHONE POULENC sous la dénomination RHODORSILs référence 71-791.  By way of example, it is advantageous to use the product sold by the company RHONE POULENC under the name RHODORSILs reference 71-791.

Pour permettre la vulcanisation, ces élastomères doivent, bien entendu, être associés à une faible proportion de catalyseurs de vulcanisation, notamment de peroxydes. To allow vulcanization, these elastomers must, of course, be associated with a small proportion of vulcanization catalysts, in particular peroxides.

Selon une autre caractéristique de l'invention, on ajoute, aux silicones, 2 à 10 W en poids d'une charge susceptible d'améliorer la conduction de la chaleur lors de la cuisson d'un aliment dans le moule. According to another characteristic of the invention, 2 to 10 W by weight of a filler capable of improving the conduction of heat during the cooking of a food in the mold are added to the silicones.

Cette charge peut être constituée par un colorant noir, de préférence par du noir de carbone, par exemple le produit commercialisé sous la référence MB-79 (SAFIC-ALCAN) ou encore par de la poudre d'aluminium. This filler can be constituted by a black dye, preferably by carbon black, for example the product sold under the reference MB-79 (SAFIC-ALCAN) or also by aluminum powder.

Il est à noter que le rôle de cette charge est, en fait, double puisqu'elle permet également de colorer le silicone qui est initialement translucide, en particulier en noir ou en gris dans le cas de la poudre d'aluminium. It should be noted that the role of this filler is, in fact, double since it also makes it possible to color the silicone which is initially translucent, in particular in black or in gray in the case of aluminum powder.

L'invention se rapporte également à un moule flexible à base de silicones destiné à l'industrie alimentaire et fabriqué comme décrit précédemment. The invention also relates to a flexible silicone-based mold intended for the food industry and manufactured as described above.

Un tel moule est caractérisé en ce qu'il présente une épaisseur moyenne de l'ordre de 1,5 à 2 mm, ce qui lui confère une très grande souplesse et une large faculté de déformation ; de plus, la mise en oeuvre d'un processus de moulage par compression permet d'obtenir des surfaces extrêmement lisses et donc fortement anti-adhérentes, ce qui évite tout risque de collage du produit cuit sur les parois du moule. Such a mold is characterized in that it has an average thickness of the order of 1.5 to 2 mm, which gives it very great flexibility and a large capacity for deformation; moreover, the implementation of a compression molding process makes it possible to obtain extremely smooth and therefore highly non-stick surfaces, which avoids any risk of sticking of the cooked product on the walls of the mold.

Un autre avantage du moulage par compression est lié au fait que ce processus permet de reproduire toutes les formes de moules métalliques existant aujourd'hui, y compris les plus compliquées et même celles comportant des angles droits, par exemple des plaques munies d'alvéoles semisphériques. Another advantage of compression molding is linked to the fact that this process makes it possible to reproduce all the forms of metal molds existing today, including the most complicated and even those comprising right angles, for example plates provided with semispherical cells. .

Le moule, conforme à l'invention, se distingue par ailleurs par sa faculté de résister à une très large plage de températures allant d'environ -500C à +3000C. The mold, in accordance with the invention, is further distinguished by its ability to withstand a very wide range of temperatures from around -500C to + 3000C.

Il est, en outre, à noter que le moule conforme à l'invention peut correspondre à une feuille munie d'un décor en relief permettant de mouler des biscuits destinés à l'entourage de gâteaux ; conformément à cette variante de l'invention, l'utilisation d'une charge en poudre d'aluminium s'avère particulièrement satisfaisante. It should also be noted that the mold in accordance with the invention may correspond to a sheet provided with a relief decoration making it possible to mold cookies intended for surrounding cakes; in accordance with this variant of the invention, the use of an aluminum powder filler proves to be particularly satisfactory.

L'invention se rapporte également à un procédé de fabrication par moulage par compression du moule flexible susmentionné. The invention also relates to a manufacturing method by compression molding of the above-mentioned flexible mold.

Ce procédé est caractérisé par la succession des étapes suivantes
préchauffage à environ 1000C du moule d'une presse de moulage
à chaud constitué d'un poinçon et d'une matrice munie d'une
empreinte correspondant à la pièce à mouler, ces deux élé
ments étant respectivement fixés aux plateaux de la presse,
mise en place de l'élastomère à mouler dans l'empreinte de la
matrice,
fermeture du moule et compression de l'élastomère sous une
pression de l'ordre de 240 tonnes,
maintien du moule fermé pendant 5 à 10 min. de façon à per
mettre la vulcanisation de l'élastomère,
ouverture du moule et extraction de la pièce moulée.This process is characterized by the succession of the following stages
preheating of the mold of a molding press to around 1000C
hot consisting of a punch and a die provided with a
footprint corresponding to the part to be molded, these two elements
elements being respectively fixed to the press plates,
fitting of the elastomer to be molded into the impression of the
matrix,
closing the mold and compressing the elastomer under a
pressure of the order of 240 tonnes,
keeping the mold closed for 5 to 10 min. so as to per
put the vulcanization of the elastomer,
opening of the mold and extraction of the molded part.

Il s'agit là d'un procédé classique utilisé dans une large gamme d'industries (aéronautique, armement, automobile, ...) et dont les différents paramètres sont adaptés aux spécificités du matériau à traiter et à l'industrie alimentaire. This is a classic process used in a wide range of industries (aeronautics, armaments, automotive, ...) and whose different parameters are adapted to the specifics of the material to be treated and to the food industry.

Selon une autre caractéristique de l'invention, on met en oeuvre une étape préalable d'incorporation d'une charge et de mélange sur un mélangeur à cylindre. According to another characteristic of the invention, a prior step of incorporating a filler and mixing is carried out on a cylinder mixer.

Cette étape préalable, au terme de laquelle l'élastomère demeure malléable, permet de replastifier celui-ci afin de faciliter sa mise en place dans l'empreinte de la matrice et de permettre une bonne répartition. This preliminary step, at the end of which the elastomer remains malleable, makes it possible to replastify the latter in order to facilitate its positioning in the imprint of the matrix and to allow good distribution.

Selon une autre caractéristique de l'invention, on met en oeuvre une étape finale de traitement en étuve de la pièce moulée pendant environ 16 heures à une température d'environ 1000C. According to another characteristic of the invention, a final step of treatment in an oven of the molded part is carried out for approximately 16 hours at a temperature of approximately 1000C.

Cette opération permet d'éviter tout phénomène de réversion provoquant une dégradation du silicone vulcanisé en molécules plus courtes, de neutraliser les odeurs de caoutchouc, et surtout, d'éliminer les traces de catalyseurs pouvant être demeurées dans le produit après moulage afin de le rendre alimentaire.  This operation makes it possible to avoid any phenomenon of reversion causing degradation of the vulcanized silicone into shorter molecules, to neutralize the odors of rubber, and above all, to eliminate the traces of catalysts which may have remained in the product after molding in order to make it food.
