Abstract

Device for demoulding industrial food products cooked in moulds, characterised in that it comprises a vibrating sonotrode 14 emitting ultrasound waves, whose end is applied against that part of the mould 10 which is most favourable to the propagation of a high-frequency vibration during the operation of removing the product 12 cooked in this mould, producing a good coupling between the mould and the sonotrode in order to enhance removal of the product by virtue of the relative high-frequency movement between the contact surfaces of the mould and of the product contained in the latter.

Description

Cette invention est relative à la fabrication de produits alimentaires industriels, et elle concerne plus particulièrement la fabrication de produits alimentaires comportant une étape de cuisson dans des moules. This invention relates to the manufacture of industrial food products, and it relates more particularly to the manufacture of food products comprising a cooking step in molds.

On sait que la cuisson de tels produits alimentaires industriels entraîne une adhérence des produits dans le moule de cuisson, et que, dans certains modes de conditionnement, il est nécessaire d'extraire le produit de son moule après cuisson, le moule étant ensuite nettoyé, puis recyclé, pour une opération suivante de cuisson. It is known that cooking such industrial food products causes adhesion of the products in the cooking mold, and that, in certain modes of packaging, it is necessary to extract the product from its mold after cooking, the mold then being cleaned, then recycled, for a next cooking operation.

L'expérience montre que l'opération d'extraction du produit cuit de son moule est difficile et délicate à mener à bien, en raison de l'adhérence produitmoule, provoquée par la cuisson, et, pour pallier cette difficulté, on a généralement recours, dans la fabrication industrielle de produits alimentaires moulés, à des moules comportant un revêtement de surface constitué d'une pellicule de silicone ou de polytétrafluoréthylène ("Téflon"), ou bien par un badigeonnage de graisse. Cependant, la durée de vie d'une telle pellicule est relativement courte, et il est nécessaire de procéder périodiquement au renouvellement du revêtement de surface de moule, cette opération étant effectuée tous les quinze jours, pour une entreprise travaillant en 2 x 8 heures. Experience shows that the operation of extracting the cooked product from its mold is difficult and delicate to carry out, due to the adhesion of the mold produced by cooking, and, to overcome this difficulty, recourse is generally made to , in the industrial manufacture of molded food products, in molds comprising a surface coating consisting of a film of silicone or of polytetrafluoroethylene ("Teflon"), or else by brushing with grease. However, the lifespan of such a film is relatively short, and it is necessary to periodically renew the mold surface coating, this operation being carried out every fortnight, for a company working in 2 x 8 hours.

Une telle opération est couteuse. Pour donner un ordre de grandeur, on précisera qu'elle peut représenter environ 800.000 Francs de charges par an, pour une entreprise importante. Par ailleurs, un tel procédé, outre son cout important, présente de gros inconvénients : en effet, dans le cas d'un revetement mal exécuté ou d'un revetement qui approche de sa limite de durée de vie, le poste d'extraction du produit du moule ne réussit pas toujours à remplir complètement sa mission, et de nombreux moules arrivent encore pleins au poste de nettoyage suivant, ce qui perturbe profondément le fonctionnement de la chaîne de fabrication. Pour pallier ces difficultés, on est amené, à l'heure actuelle, à pratiquer une intervention manuelle pour enlever les produits du moule, ce qui interdit toute possibilité d'effectuer un nettoyage industriel automatique de la totalité des moules. Such an operation is expensive. To give an order of magnitude, it will be specified that it can represent approximately 800,000 Francs of charges per year, for a large company. In addition, such a process, in addition to its significant cost, has major drawbacks: in fact, in the case of a poorly executed coating or a coating that approaches its lifetime limit, the extraction station of the mold product does not always succeed in completely fulfilling its mission, and many molds still arrive full at the next cleaning station, which profoundly disrupts the functioning of the production line. To overcome these difficulties, it is necessary, at present, to practice manual intervention to remove the products from the mold, which prohibits any possibility of carrying out an automatic industrial cleaning of all the molds.

La présente invention se propose d'apporter une solution à ce problème. The present invention proposes to provide a solution to this problem.

Elle a donc pour objet un dispositif permettant d'assurer le démoulage de produits alimentaires cuits dans un moule caractérisé en ce qu'il comporte une sonotrode vibrante émettant des ultrasons, dont l'extrémité vient s'appliquer contre la partie du moule la plus favorable à la propagation d'une vibration haute fréquence, lors de l'opération d'extraction du produit cuit du moule, en réalisant un bon couplage entre la sonotrode et le moule, afin de favoriser l'extraction grâce au mouvement relatif à haute fréquence entre les surfaces de contact du moule et du produit contenu dans celui-ci.  It therefore relates to a device for ensuring the release of food products cooked in a mold characterized in that it comprises a vibrating sonotrode emitting ultrasound, the end of which is applied against the most favorable part of the mold to the propagation of a high frequency vibration, during the operation of extracting the cooked product from the mold, by making a good coupling between the sonotrode and the mold, in order to favor the extraction thanks to the relative movement at high frequency between the contact surfaces of the mold and of the product contained therein.

D'autres caractéristiques et avantages de cette invention ressortiront de la description faite ci-après en référence au dessin annexé, dont la Figure unique est une vue schématique, en élévation latérale, d'un dispositif selon cette invention. Other characteristics and advantages of this invention will emerge from the description given below with reference to the appended drawing, the single figure of which is a schematic view, in side elevation, of a device according to this invention.

Sur la Figure, on a schématisé, en 10, un moule métallique servant à la cuisson d'un gâteau du type "cake", ce gâteau devant être extrait du moule à l'aide d'un moyen d'éjection ou d'extraction réalisé, par exemple, sous la forme d'une ventouse 16. In the Figure, there is shown diagrammatically, at 10, a metal mold used for baking a cake of the "cake" type, this cake having to be extracted from the mold using an ejection or extraction means. produced, for example, in the form of a suction cup 16.

Selon l'invention, simultanément à l'opération d'extraction à l'aide de la ventouse, on applique l'extrémité d'une sonotrode vibrante 14, émettant des ultrasons, contre le fond métallique extérieur du moule 10, en veillant à obtenir un bon couplage entre la sonotrode et le moule, par exemple par l'application d'une force de pressage appropriée de la sonotrode contre la surface extérieure du fond du moule. Grâce à cette disposition, la vibration à haute fréquence se propage à toute la masse métallique du moule, tandis que le produit alimentaire cuit 12, présent dans le moule 10, constitué de matières réfractaires à la diffusion des vibrations, reste parfaitement inerte. Il en résulte un mouvement relatif à haute fréquence entre les surfaces de contact du produit 12 et du moule 10, favorisant le démoulage et permettant l'extraction du produit en quelques dixièmes de seconde. According to the invention, simultaneously with the extraction operation using the suction cup, the end of a vibrating sonotrode 14, emitting ultrasound, is applied against the external metal base of the mold 10, taking care to obtain good coupling between the sonotrode and the mold, for example by applying an appropriate pressing force of the sonotrode against the external surface of the bottom of the mold. Thanks to this arrangement, the high frequency vibration propagates throughout the metal mass of the mold, while the cooked food product 12, present in the mold 10, made of materials refractory to the diffusion of vibrations, remains perfectly inert. This results in a relative movement at high frequency between the contact surfaces of the product 12 and the mold 10, favoring demolding and allowing the product to be extracted in a few tenths of a second.

L'invention, grâce à l'assistance du démoulage par ultrasons, permet donc d'éviter les problèmes résultant de l'utilisation antérieure de pellicules de silicone ou de "Téflon", et, par conséquent, elle permet de réaliser un nettoyage automatique industriel en aval de tous les moules. The invention, thanks to the assistance of demoulding by ultrasound, therefore makes it possible to avoid the problems resulting from the prior use of silicone or "Teflon" films, and, consequently, it makes it possible to carry out automatic industrial cleaning. downstream of all molds.

Les avantages apportés par l'invention sont donc les suivants - élimination de la nécessité de déposer dans les moules un revêtement de ma
tériaux facilitant le démoulage (tels que silicone, "téflon" et similaires) ; - élimination du graissage du moule - possibilité d'obtenir une salissure qualitativement et quantitativement ré
gulière du moule, pouvant être nettoyée automatiquement.
The advantages provided by the invention are therefore the following - elimination of the need to deposit in the molds a coating of my
materials facilitating release from the mold (such as silicone, "teflon" and the like); - elimination of greasing from the mold - possibility of obtaining a qualitatively and quantitatively re soiling
mold mold, which can be cleaned automatically.

Il demeure bien entendu que cette invention n'est pas limitée à l'exemple de réalisation décrit et représente ici, mais qu'elle en englobe toutes les variantes.  Obviously, this invention is not limited to the embodiment described and shown here, but that it encompasses all variants.
