Description

UNITS DE CUISSON ET DE REFROIDISSEMENT EN
CONTINU DE PRODUITS ALIMENTAIRES PRA-CONDITIONNtS
La présente invention a pour objet une unité de cuisson et de refroidissement en continu de produits alimentaires pré-conditionnés
Elle est destinée au traitement des produits en contenants ouverts ou obturés, et en particulier des produits en barquettes équipées de valves therino-fusibles. COOKING AND COOLING UNITS IN
CONTINUOUS PRA-CONDITIONING FOOD PRODUCTS
The present invention relates to a continuous cooking and cooling unit for pre-packaged food products
It is intended for the treatment of products in open or closed containers, and in particular products in trays equipped with thermo-fusible valves.

Il est connu d'utiliser pour la cuisson ou la réfrigération des aliments en continu ou en discontinu divers équipements sous forme de tunnels linéaires, de balancelles verticales ou horizontales, de convoyeurs horizontaux effectuant des allers-retours dans des enceintes chauffees et/ou réfrigérées. Ces dispositifs sont généralement encombrants et nécessitent des surfaces complémentaires de chargement et déchargement ains que des manipulations importantes voire des systèmes additionnels de manutentions automatiques. It is known to use for cooking or refrigerating food continuously or discontinuously various equipment in the form of linear tunnels, vertical or horizontal swings, horizontal conveyors performing back and forth in heated and / or refrigerated enclosures. These devices are generally bulky and require additional loading and unloading surfaces as well as significant handling or even additional automatic handling systems.

Le dispositif selon la presente invention supprime ces inconvenients. En effet, grâce à deux enceintes separees pour la cuisson et le refroidissement il permet d'éviter les attentes inutiles et le ralentissement de la production qui sont le lot des appareils mono-enceinte dans lesquels on cuit puis on refroidit consécutivement les produits. The device according to the present invention eliminates these drawbacks. Indeed, thanks to two separate enclosures for cooking and cooling it avoids unnecessary waiting and the slowdown in production which are the lot of mono-enclosure devices in which we cook and then consecutively cool the products.

Il est constitue par la combinaison de deux enceintes séparées et distinctes, la première destinée à la cuisson, la seconde au refroidissement rapide ou à la surgélation, et d'un double convoyeur hélicoïdal parcourant successivement l'enceinte de cuisson sous la forme d'une spirale ascendante et l'enceinte de réfrigération sous la forme d'une spirale hélicoïdale descendante, la sortie du convoyeur s'effectuant à la base de l'enceinte, de préférence au même niveau que l'entrée dans l'enceinte de cuisson. It is constituted by the combination of two separate and distinct enclosures, the first intended for cooking, the second for rapid cooling or freezing, and a double helical conveyor successively traversing the cooking enclosure in the form of a upward spiral and the refrigeration enclosure in the form of a downward helical spiral, the conveyor outlet being carried out at the base of the enclosure, preferably at the same level as the entry into the cooking enclosure.

La description détaillée ci-après se rapporte à un exemple non limitatif d'une des formes de réalisation de l'objet de l'invention, en se référant au dessin annexé. The detailed description below relates to a non-limiting example of one of the embodiments of the subject of the invention, with reference to the attached drawing.

Le dispositif est constitué d'une unité comportant deux enceintes 1, 2 séparées et distinctes, la première destinée à la cuisson, la seconde au refroidissement rapide ou à la surgélation. The device consists of a unit comprising two separate and distinct chambers 1, 2, the first intended for cooking, the second for rapid cooling or freezing.

Un convoyeur hélicoïdal 3 parcourt sous la forme d'une spirale ascendante 4 la première enceinte de cuisson 1. L'entrée du convoyeur se situe à la base de l'enceinte, tandis que la sortie s'effectue à la partie supérieure. A helical conveyor 3 travels in the form of an ascending spiral 4 the first cooking enclosure 1. The inlet of the conveyor is located at the base of the enclosure, while the outlet takes place at the top.

Ce meme convoyeur entre alors dans l'enceinte de réfrigération 2 par sa partie supérieure et parcourt celle-ci sous la forme d'une spirale hélicoïdale descendante 5. La sortie du convoyeur s'effectue à la base de l'enceinte, de préférence au même niveau que l'entrée dans l'enceinte de cuisson. This same conveyor then enters the refrigeration enclosure 2 through its upper part and traverses the latter in the form of a descending helical spiral 5. The conveyor leaves at the base of the enclosure, preferably at the same level as entering the cooking chamber.

Le convoyeur est ramené à son point d'origine par un nombre suffisant de tambours de renvoi 6, après passage sur un dispositif de tension automatique 7. The conveyor is returned to its point of origin by a sufficient number of return drums 6, after passing through an automatic tensioning device 7.

Les barquettes 8 ou contenants sont deposés automatiquement sur le convoyeur hélicoïdal des leur sortie de la ligne de remplissage et/ou d'operculage 9.  The trays 8 or containers are automatically deposited on the helical conveyor as soon as they leave the filling and / or sealing line 9.

Ils sont véhicules sans autre manipulation au travers de la première enceinte de cuisson 1, puis dès la fin de la cuisson, ils traversent l'enceinte de réfrigération 2.They are transported without further manipulation through the first cooking enclosure 1, then as soon as the cooking is finished, they pass through the refrigeration enclosure 2.

Au terme de ce double traitement, les barquettes 8 ou les contenants peuvent sortir directement en chambre froide de stockage. Cette dernière opération pouvant s'effectuer egalement automatiquement par des convoyeurs à tapis ou à rouleaux motorisés ou non. At the end of this double treatment, the trays 8 or the containers can be taken out directly into the cold storage room. This latter operation can also be carried out automatically by conveyor belts or with motorized or non-motorized rollers.

La partie horizontale du convoyeur 3 situee entre la sortie de l'enceinte de cuisson 1 et l'entrée de l'enceinte de réfrigération 2 peut être de longueur variable selon l'espace disponible ou souhaite entre les deux enceintes. The horizontal part of the conveyor 3 located between the outlet of the cooking enclosure 1 and the inlet of the refrigeration enclosure 2 may be of variable length depending on the space available or desired between the two enclosures.

Pour des impératifs d'implantation ou pour des raisons techniques de différences de dilatation par exemple, le convoyeur unique d'une seule pièce peut avantageusement etre remplacé par deux convoyeurs indépendants. Il devient alors possible d'installer les deux enceintes 1, 2 soit en ligne, soit à angle droit l'une part rapport à l'autre. For installation requirements or for technical reasons of differences in expansion, for example, the single conveyor in one piece can advantageously be replaced by two independent conveyors. It then becomes possible to install the two speakers 1, 2 either in line or at right angles to each other.

Dans le cas d'une utilisation de cuisson en barquettes à valves thermofusibles, il est possible et conseillé de faire passer la partie supérieure horizontale du ou des convoyeurs 3 située entre les deux enceintes dans un mini tunnel réfrigéré 10. Ce dernier est destine à figer instantanément les valves thermofusibles des barquettes avant la phase de réfrigération. In the case of cooking in trays with hot-melt valves, it is possible and advisable to pass the horizontal upper part of the conveyor (s) 3 located between the two enclosures in a mini refrigerated tunnel 10. The latter is intended to freeze instantly the hot-melt valves of the trays before the refrigeration phase.

L'enceinte de cuisson 1 peut être dotee d'un système à air chaud pulsé, d'un générateur de vapeur, d'un système mixte vapeur + air pulsé. Elle peut fonctionner à l'électricité ou au gaz indifféremment sans que cela ne puisse remettre en cause l'objet de la présente invention.  The cooking chamber 1 can be provided with a forced hot air system, a steam generator, a mixed steam + forced air system. It can operate on electricity or gas indifferently without this could call into question the object of the present invention.

L'enceinte de réfrigération 2 peut être réfrigérée indifferemment par un procédé mécanique compresseur et évaporateur, ou par un procédé cryogénique
injection d'un gaz liquide azote (N2L) ou Anhydride
Carbonique (C02) sans que cela ne puisse remettre en cause l'objet de l'invention.The refrigeration chamber 2 can be refrigerated either by a mechanical compressor and evaporator process, or by a cryogenic process
injection of a liquid nitrogen gas (N2L) or Anhydride
Carbonic (C02) without this could call into question the object of the invention.

Le positionnement des divers éléments constitutifs donne à l'objet de l'invention un maximum d'effets utiles qui n'avaient pas été, à ce jour, obtenus par des dispositifs similaires.  The positioning of the various constituent elements gives the object of the invention a maximum of useful effects which had not, to date, been obtained by similar devices.
