Description

TUNNEL DE SURGELATION DE PRODUITS /ALIMENTAIRES A FILM D'ENTRAINEMENT INTERROMPU. PRODUCT / FOOD FREEZING TUNNEL WITH INTERRUPTED DRIVE FILM.
La présente invention a pour objet un tunnel de surgélation de produits alimentaires à film d'entraînement interrompu.The present invention relates to a tunnel for freezing food products with an interrupted drive film.
Il peut convenir à de nombreux types de produits susceptibles d'être surgelés, mais est surtout destiné au traitement des produits de faible épaisseur, en portions ou étalés en tapis, et aux produits liquides ou semi-liquides.It can be suitable for many types of products that can be frozen, but is especially intended for the treatment of thin products, in portions or spread out in carpets, and to liquid or semi-liquid products.
Dans le domaine de la conservation des aliments par le froid, lorsqu'on descend au-dessous de 0 °C, on parle de congélation, qui peut être ordinaire ou lente, aboutissant à des produits congelés, ou rapide et profonde, aboutissant à des produits surgelés qui, à la décongélation reprendront leur aspect initial . La surgélation des produits alimentaires s'effectue le plus souvent en continu dans des tunnels réfrigérés, où ces produits effectuent un parcours plus ou moins élaboré sur un ou plusieurs convoyeurs à bande. Les produits frais ou préparés comportent une proportion importante d'eau qui, en gelant durant le processus de refroidissement, a tendance à provoquer une adhérence sur les bandes transporteuses, nécessitant un système de raclage risquant de détériorer le produit. En outre, la sublimation de l'eau congelée est responsable d'une certaine déshydratation entraînant une perte de poids des aliments traités, et provoquant le givrage des évaporateurs des machines frigorifiques. Un brevet du même inventeur, publié sous le Nc FR 2 744 884, décrit un tunnel de surgélation comportant en partie supérieure, à l'intérieur de l'enceinte refroidie, un dispositif de pré-refroidissement constitué d'un film souple non réutilisable défilant sur un support horizontal fixe, en sens inverse de celui du convoyeur à bande ou du lit fluidisé situé au-dessous, l'ensemble étant agencé pour que les produits à surgeler soient préalablement refroidis sur ce film de manière à provoquer une croûte de glace à leur surface, avant d'être surgelés sur le ou les convoyeurs à bande ou par le lit fluidisé.In the field of food preservation by cold, when it drops below 0 ° C, we speak of freezing, which can be ordinary or slow, leading to frozen products, or fast and deep, leading to frozen products which, when thawed, will resume their initial appearance. Freezing of food products is most often carried out continuously in refrigerated tunnels, where these products follow a more or less elaborate route on one or more conveyor belts. Fresh or prepared products contain a significant proportion of water which, freezing during the cooling process, tends to cause adhesion on the conveyor belts, requiring a scraping system which risks damaging the product. In addition, the sublimation of frozen water is responsible for a certain dehydration leading to a loss of weight in the treated food, and causing the icing of the evaporators of the refrigerating machines. A patent of the same inventor, published under No. c FR 2 744 884, describes a deep-freezing tunnel comprising in the upper part, inside the cooled enclosure, a pre-cooling device made up of a flexible film which cannot be reused. running on a fixed horizontal support, opposite to that of the belt conveyor or the fluidized bed located below, the assembly being arranged so that the products to be frozen are previously cooled on this film so as to cause an ice crust on their surface, before being frozen on the belt conveyor (s) or by the fluidized bed.
Ce système permet d'éviter la déformation des produits à traiter au cours du processus et les pertes de poids par déshydratation, ainsi que l'accumulation de givre sur les évaporateurs . Toutefois, l'équipement ainsi obtenu ayant des dimensions identiques à celles d'un tunnel de surgélation habituel, ne permet pas de résoudre le problème de l'encombrement de l'ensemble, ni celui inhérent à la présence des convoyeurs à bande, en particulier en ce qui concerne les questions d'hygiène.This system prevents deformation of the products to be treated during the process and weight loss by dehydration, as well as the accumulation of frost on the evaporators. However, the equipment thus obtained having dimensions identical to those of a usual deep-freezing tunnel, does not make it possible to solve the problem of the overall size, nor that inherent in the presence of belt conveyors, in particular with regard to hygiene issues.
La demande de brevet N° FR 97 00 307, déposée également par le demandeur, fait état d'une enceinte de surgélation en continu à tables réfrigérées superposées constituée de plaques creuses dans lesquelles un réfrigérant est recyclé et disposées en quinconce les unes au-dessus des autres, les produits à surgeler défilant successivement sur ces plaques entraînés par des supports minces convoyeurs reposant sur elles et constitués de films à usage unique sur bobines, ou en boucle conçus pour être remplacés périodiquement, de l'air à basse température étant diffusé sur les produits pendant leur avancée en contact avec les plaques réfrigérées au moyen de caissons perforés. Ces installations sont destinées à la surgélation soit de produits en vrac tels que légumes frais ou préparés, petits pois ou haricots verts, par exemple, soit d'aliments se présentant sous forme de purée, de produits liquides ou semi-liquides, ou de portions individuelles comme steaks hachés, filets de poissons ou de viandes.Patent application No. FR 97 00 307, also filed by the applicant, describes a continuous deep-freezing chamber with superimposed refrigerated tables made up of hollow plates in which a refrigerant is recycled and arranged in staggered rows one above the other others, the products to be frozen running successively on these plates driven by thin conveyor supports resting on them and made up of single-use films on reels, or in a loop designed to be replaced periodically, low temperature air being diffused on the products during their advance in contact with the refrigerated plates by means of perforated boxes. These facilities are intended for deep-freezing either bulk products such as fresh or prepared vegetables, peas or green beans, for example, or food in the form of mash, liquid or semi-liquid products, or portions as individual hamburger steaks, fish or meat fillets.
L'invention a pour objectif de permettre la surgélation de certains produits dans des conditions mieux adaptées en proposant une machine présentant les avantages procurés par les films convoyeurs à usage unique tout en ayant un excellent rendement et un encombrement réduit.The invention aims to allow the freezing of certain products under better conditions by providing a machine with the advantages of single-use conveyor films while having excellent performance and reduced bulk.
Elle est constituée d'un tunnel de surgélation en continu équipé d'une table réfrigérée formée d'un élément d'entrée, d'un élément central et d'un élément de sortie, un film souple non réutilisable défilant sur les éléments d'entrée et de sortie, le premier élément étant agencé pour provoquer un croûtage de la face inférieure du produit à surgeler afin qu'il puisse glisser sur l'élément central dépourvu de film, la progression des produits en morceaux étant assurée sur cet élément par un convoyeur à palettes .It consists of a continuous freezing tunnel equipped with a refrigerated table formed of an input element, a central element and an output element, a flexible non-reusable film passing over the elements of inlet and outlet, the first element being arranged to cause crusting of the underside of the product to be frozen so that it can slide on the central element devoid of film, the progression of the products in pieces being ensured on this element by a pallet conveyor.
Sur les dessins schématiques annexés, donnés à titre d'exemples non limitatifs de formes de réalisation de l'objet de l'invention: la figure 1 représente en coupe verticale longitudinale un tunnel de surgélation pour produits en continu à film d'entraînement en deux parties, la figure 2 montre dans les mêmes conditions un tunnel du même type à film d'entraînement d'un seul tenant et à table réfrigérée inclinée, la figure 3 représente un tunnel de surgélation pour produits en portions, à film d'entraînement d'un seul tenant et la figure 4 montre, toujours dans les mêmes conditions, un tunnel du même type à film d'entraînement en deux parties et à table réfrigérée inclinée.In the appended schematic drawings, given by way of nonlimiting examples of embodiments of the subject of the invention: FIG. 1 shows in longitudinal vertical section a freezing tunnel for continuous products with a drive film in two parts, FIG. 2 shows, under the same conditions, a tunnel of the same type with a driving film in one piece and with an inclined refrigerated table, FIG. 3 represents a freezing tunnel for products in portions, with driving film of a in one piece and Figure 4 shows, still under the same conditions, a tunnel of the same type with a two-part drive film and an inclined refrigerated table.
Le dispositif, figures 1 à 4, est un système mécanique de refroidissement constitué d'un tunnel 1 de surgélation comportant une enceinte isotherme et une table réfrigérée sur laquelle se déplace un support mince 2 non réutilisable assurant la progression des produits alimentaires 3 à surgeler, l'enceinte étant refroidie par un évaporateur 4 interne associé à des ventilateurs 5.The device, FIGS. 1 to 4, is a mechanical cooling system consisting of a freezing tunnel 1 comprising an isothermal enclosure and a refrigerated table on which a thin support 2 which cannot be reused moves the food products 3 to be frozen, the enclosure being cooled by an internal evaporator 4 associated with fans 5.
La table réfrigérée est formée de trois éléments successifs, un élément d'entrée 6, un élément intermédiaire 7 et un élément de sortie 8. Ces éléments sont constitués de plaques creuses dans lesquelles circule un réfrigérant à basse température en circuit fermé. Elles agissent suivant deux effets d'échange thermique, par contact, et en jouant le rôle d ' évaporateur à air. Les éléments d'entrée 6 et de sortie 8 sont recouverts d'un film convoyeur 2 glissant en contact avec la surface supérieure des plaques .The refrigerated table is formed of three successive elements, an input element 6, an intermediate element 7 and an output element 8. These elements consist of hollow plates in which a low temperature refrigerant circulates in a closed circuit. They act according to two heat exchange effects, by contact, and by playing the role of air evaporator. The inlet 6 and outlet 8 elements are covered with a conveyor film 2 sliding in contact with the upper surface of the plates.
Afin d'améliorer le rendement de l'installation, l'élément intermédiaire 7 est dépourvu de film convoyeur 2, les produits 3 à traiter étant ainsi en contact sans intermédiaire avec la table réfrigérée.In order to improve the efficiency of the installation, the intermediate element 7 is devoid of conveyor film 2, the products 3 to be treated thus being in direct contact with the refrigerated table.
Pour les produits 3 en continu (figures 1 et 2), la progression sur cet élément est assurée par les éléments d'entrée et de sortie qui poussent et tirent la nappe formée par ledit produit. En outre, l'élément d'entrée 6 ayant essentiellement pour but de glacer le produit 3 à surgeler, au moins sur sa face inférieure, afin de réaliser un croûtage, la nappe glisse aisément sur l'élément intermédiaire.For products 3 continuously (Figures 1 and 2), progression on this element is ensured by input and output elements which push and pull the web formed by said product. In addition, the input element 6 having essentially the purpose of freezing the product 3 to be frozen, at least on its underside, in order to make a crusting, the sheet slides easily on the intermediate element.
En vue de faciliter ce déplacement, la table réfrigérée peut avantageusement être inclinée vers la sortie d'un angle inférieur ou égal à 15 ° (figures 2 et 4) .In order to facilitate this movement, the refrigerated table can advantageously be inclined towards the outlet at an angle less than or equal to 15 ° (Figures 2 and 4).
Pour les produits 3 à surgeler se présentant en portions ou en morceaux (figures 3 et 4 ) , la progression sur est assurée au moyen d'un convoyeur 9 à palettes 10 disposé au-dessus de celui-ci et débordant sur les autres éléments .For the products 3 to be frozen which are presented in portions or in pieces (FIGS. 3 and 4), the progression over is ensured by means of a conveyor 9 with pallets 10 disposed above it and overflowing onto the other elements.
Le film convoyeur 2 peut être d'un seul tenant. Provenant d'une bobine débitrice 11, passant successivement sur l'élément d'entrée 6, au-dessous de l'élément central 7, puis sur l'élément de sortie 8 avant d'aboutir à une bobine réceptrice 12 motorisée (figures 2 et 3) .The conveyor film 2 can be in one piece. Coming from a supply coil 11, passing successively on the input element 6, below the central element 7, then on the output element 8 before arriving at a motorized take-up coil 12 (Figures 2 and 3).
Ce film peut également être en deux parties, une passant sur l'élément d'entrée 6, l'autre passant sur l'élément de sortie 8, chacun de ces deux éléments comportant une bobine débitrice 11 et une bobine réceptrice 12.This film can also be in two parts, one passing over the input element 6, the other passing over the output element 8, each of these two elements comprising a supply reel 11 and a take-up reel 12.
Dans le cas d'un produit 3 en continu l'installation pourra comporter à la sortie, après la surgélation partielle ou totale (figures 1 et 2), un dispositif de type guillotine 13 à mouvement alternatif vertical ou rotatif permettant de débiter les produits en différentes formes, ou un dispositif (non représenté) conçu pour effectuer un formage des produits.In the case of a continuous product 3, the installation may comprise at the outlet, after partial or total freezing (Figures 1 and 2), a guillotine-type device 13 with alternating vertical or rotary movement allowing the products to be delivered in different shapes, or a device (not shown) designed to perform product shaping.
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.
