On utilise pour cela des installations dans lesquelles les produits sont, par charges successives, emmagasinés d'une façon statique et congelés ou réfrigérés. Il est également connu des installations où les produits à congeler sont portés par des bandes roulantes qui se déplacent horizontalement. Ces installations occupent habituellement une grande surface et fréquemment alimentées en froid par une installation annexe de production de froid qui ae trouve à leur proximité. Ces installations sont généralement fixes, complexes dans leur_structure et coûteuses.In the prior art, it is known to freeze or refrigerate products. For this purpose, installations are used in which the products are, by successive charges, stored in a static manner and frozen or refrigerated. It is also known installations where the products to be frozen are carried by rolling belts which move horizontally. These installations usually occupy a large area and are frequently supplied with cold by an annex cold production installation which is located nearby. These installations are generally fixed, complex in their structure and costly.

La présente invention ayant pour but d'éviter ces inconvénients, permet de réaliser une cellule économique, autonome, facilement déplaçable assurant une réfrigération ou une congélation en continu, des produits.The object of the present invention is to avoid these drawbacks and makes it possible to produce an economical, autonomous, easily movable cell ensuring continuous refrigeration or freezing of the products.

Ces parties sont verticalement superposées.The refrigeration cell shown comprises clean, autonomous means for producing cold 6 and an insulated refrigeration enclosure 8, divided internally into two parts by thermally insulating partitioning means. The first part of this enclosure or part 1 inlet, includes access means allowing the introduction of the products to be cooled and the output thereof thereof this enclosure after treatment. The second part of this enclosure, or part 2 of the treatment, provides a refrigeration treatment proper. These parts are vertically superimposed.

Un produit convenablement conditionné, est déposé dans la partie 1 d'entrée, sur des moyens de support 3, entrainés par des moyens d'entraînement ou moteur 4. Le produit passe de la partie 1 à la partie 2 à travers dés moyens de cloisonnement 5 en partie escamotables de préférence escamotables uniquement dans les zones de passage du produit soumis au traitement.A suitably packaged product is deposited in the inlet part 1, on support means 3, driven by drive or motor means 4. The product passes from part 1 to part 2 through partitioning means 5 partly retractable, preferably retractable only in the areas of passage of the product subjected to the treatment.

Les moyens de support 3, sous forme, par exemple, d'un système sans fin, comporte une chaîne 7 en une boucle simple, verticale, fermée qui porte des plateaux ou grilles 17 constamment maintenus à l'horizontal par des techniques connues. La chaîne 7 est mise en mouvement par des moyens d'entraînement ou moteur 4 pour réaliser un défilement continu des produits soumis au traitement; suivant les flèches C et D.The support means 3, in the form, for example, of an endless system, comprises a chain 7 in a simple, vertical, closed loop which carries plates or grids 17 constantly maintained horizontally by known techniques. The chain 7 is set in motion by drive means or motor 4 for carry out a continuous scrolling of the products subjected to treatment; following arrows C and D.

La cellule comporte une face.avant et une face arrière. Au niveau de la partie 1 de l'enceinte 8, la 4face avant comporte une ouverture 18 permettant l'introduction du produit conditionné dans une barquette 19 par exemple. La flèche A indique le sens d'introduction de la barquette 19. Le mouvement d'introduction suivant A est synchronisé avec un passage à ce niveau d'une grille ou plateau 17, les moyens de support 3 se déplaçant en défilement continu suivant les flèches C et D. L'ouverture 18 peut être fermée par un rideau non représenté qui s'escamote lors d'une introduction d'une barquette 19.The cell has a front face and a rear face. At the level of part 1 of the enclosure 8, the front surface has an opening 18 allowing the introduction of the packaged product into a tray 19 for example. The arrow A indicates the direction of introduction of the tray 19. The following introduction movement A is synchronized with a passage at this level of a grid or plate 17, the support means 3 moving in continuous scrolling according to the arrows C and D. The opening 18 can be closed by a curtain, not shown, which retracts when a tray 19 is introduced.

La partie 1 d'entrée de l'enceinte comporte aussi sur sa face arrière des moyens de sortie 14 comprenant une ouverture 13. Cette dernière ouverture peut être également fermée par un rideau qui s'escamote lors d'une sortie d'une barquette 19 suivant la flèche B.

The inlet part 1 also has in its upper part an opening 15 whose edge situated on the side of the front face has an inclined slope in the form of a bevel 16.

La partie 2 de l'enceinte comporte des moyens de refroidissement. Ces moyens de refroidissement comprennent un évaporateur 22 en forme de serpentin d'échange thermique 27, cet évaporateur faisant partie des moyens de production du froid 6 pour porter les produits conditionnés en barquette 19 au degré de froid désiré, pendant le temps de traitement impartiePart 2 of the enclosure includes cooling means. These cooling means comprise an evaporator 22 in the form of a heat exchange coil 27, this evaporator forming part of the means for producing cold 6 for bringing the products packaged in trays 19 to the desired degree of cold, during the treatment time allowed

Quand l'agent d'échange thermique 27 est un liquide choisi parmi l'eau, la saumure de chlorure de sodium, etc.., Ce liquide est amené à travers un ensemble robinet à flotteur-circuit de circulation 9, dans la partie 2, jusqu'à un niveau prédéterminé. La zone 11, située entre ce niveau de liquide et les moyens de cloisonnement 5, constitue une zone d'égouttage et la barquette 19 contenant le produit est étanche.When the heat exchange agent 27 is a liquid chosen from water, sodium chloride brine, etc., this liquid is brought through a float valve-circulation circuit 9 assembly, in part 2 , up to a predetermined level. Zone 11, if killed between this level of liquid and the partitioning means 5, constitutes a drip zone and the tray 19 containing the product is sealed.

Quand le liquide d'échange thermique est de l'eau, la cellule est limitée dans son traitement à une utilisation de réfrigération.When the heat exchange liquid is water, the cell is limited in its treatment to a use of refrigeration.

Quand l'agent d'échange thermique est un gaz ou l'air, il est soit pulsé par un ou plusieurs venvila- teurs non représentés soit projeté par un ou plusieurs dispositifs de pulvérisation connu non représentés.When the heat exchange agent is a gas or air, it is either pulsed by one or more fans not shown or projected by one or more known spraying devices not shown.

Représentésen dessous de l'enceinte 8, les moyens propres autonomes de production du froid 6 comprennent principalement un moto-compresseur 26, un condenseur 23, un ventilateur 24 et sôn moteur 25. Les moyens de refroidissement disposés dans la partie 2 de traitement comprennent l'évaporateur 22, alimenté en fluide fri- gogène par le circuit de ces moyens de production du froid 6, et l'agent d'échange thermique 27. Cet évaporateur 22 est un évaporateur du type à serpentin à ailettes ou à plaques de transmission thermique.Represented below the enclosure 8, the own independent means of producing the cold 6 mainly comprise a motor-compressor 26, a condenser 23, a fan 24 and its motor 25. The cooling means arranged in the processing part 2 include the evaporator 22, supplied with a refrigerant fluid by the circuit of these cold production means 6, and the heat exchange agent 27. This evaporator 22 is an evaporator of the coil type with fins or with thermal transmission plates .

La cellule selon l'invention peut être à chargement et déchargement mécanique ou entièrement manuel.The cell according to the invention can be mechanical or entirely manual loading and unloading.

Les moyens de support 3 comportent des grilles ou plateaux 17 avec ou sans bord de retenue 17b et maintenus constamment dans leur position horizontale par des moyens de type connu. Ces moyens de support 3, sont verticalement réglables et placés à une distance prédéterminée en dessous de la paroi supérieure de l'enceinte 8 pour permettre un déchargement soit par la sortie selon E c'est-à-dire l'ouverture 15 soit par l'ouverture 13, soit par l'ouverture 18.The support means 3 comprise grids or trays 17 with or without retaining edge 17b and constantly maintained in their horizontal position by means of known type. These support means 3 are vertically adjustable and placed at a predetermined distance below the upper wall of the enclosure 8 to allow unloading either by the outlet along E, that is to say the opening 15 or by the opening 13, i.e. through opening 18.

Le chargement peut se faire par un chargeur non représenté qui place les barquettes 19 sur les grilles ou plateaux 17, à travers l'ouverture 18. Le déchargement peut se faire par un déchargeur qui saisit Les barquettes traitées 19 et les fait sortir par l'ouverture 13.The loading can be done by a charger not shown which places the trays 19 on the grids or trays 17, through the opening 18. Unloading can be done by an unloader which grabs the treated trays 19 and takes them out through the opening 13.

Dans une autre variante de réalisation, le chargement et le déchargement sont effectués manuellement, à travers la seule ouverture 18, la grille ou plateau 17 déchargée étant immédiatement rechargée par une nouvelle barquette 19 à refroidir. Dans ce cas, une seule ouverture 18 est ouverte pendant le chargement-déchargement. Les deux autres ouvertures 15 et 13 sont fermées par des portes ou volets non représentés.In another alternative embodiment, loading and unloading are carried out manually, through the single opening 18, the grid or tray 17 discharged being immediately recharged by a new tray 19 to be cooled. In this case, a single opening 18 is open during loading-unloading. The other two openings 15 and 13 are closed by doors or shutters not shown.

Dans un autre exemple de réalisation, le chargement. par l'ouverture, 18 et le déchargement par sortie E sont entièrement automatiques. Des moyens de chargement amènent des barquettes 19 à traiter dans la partie 1 d'entrée par l'ouverture 18 selon la flèche A, en synchronisme avec des passages des grilles 17. Les grilles 17, montées comme précédemment sur les moyens de support 3, comportent, un fond 17a et au moins un bord 17b placé à l'opposé du côté d'introduction de la barquette 19 poussée par les moyens de chargement selon la flèche A. Ce bord 17b permet d'une part de limiter la course de la barquette 19 introduite sùivant A et d'autre part, la grille 17 ayant accomplie son parcours complet dans l'enceinte 8, de sortir la barquette 19 de l'enceinte 8 en la poussant par derrière selon la flèche E sur le bord en biseau 16 de l'ouverture 15. Les moyens de support 3 doivent dans cet exemple être montés près de la paroi supérieure de l'enceinte 8 de sorte que chaque grille ou plateau 17 passe juste sous le biseau 16 de l'ouverture 15, et que le bord en biseau 16 puisse s'introduire sous la barquette 19 pour la sortir et la bousser dans des moyens de transport tel qu'un tapis roulant non représenté, monté à l'extérieur de l'enceinte 8, qui l'éloigne de la cellule.In another exemplary embodiment, the loading. by opening, 18 and unloading by outlet E are fully automatic. Loading means cause trays 19 to be treated in the inlet part 1 through the opening 18 according to arrow A, in synchronism with passages of the grids 17. The grids 17, mounted as previously on the support means 3, comprise, a bottom 17a and at least one edge 17b placed opposite the insertion side of the tray 19 pushed by the loading means according to arrow A. This edge 17b allows on the one hand to limit the stroke of the tray 19 introduced following A and on the other hand, the grid 17 having completed its complete course in the enclosure 8, to remove the tray 19 from the enclosure 8 by pushing it from behind according to the arrow E on the beveled edge 16 of the opening 15. The support means 3 must in this example be mounted near the upper wall of the enclosure 8 so that each grid or plate 17 passes just under the bevel 16 of the opening 15, and that the bevelled edge 16 can be introduced under the tray 19 to take it out and push it in means of transport such as a treadmill not shown, mounted outside the enclosure 8, which moves it away from the cell.

Dans cette variante, les deux ouvertures 15 et 18 sont ouvertes au moins pendant le chargement ou le déchargement. L'ouverture 13 est fermée par un volet ou porte non représenté. Les ouvertures 15 et 18, pour limiter les déperditions de froid, peuvent comporter des volets de fermeture souples ou des portes escamotables au passage des barquettes 19.In this variant, the two openings 15 and 18 are open at least during loading or unloading. The opening 13 is closed by a shutter or door not shown. The openings 15 and 18, in order to limit the loss of cold, may include flexible closing flaps or retractable doors when the trays 19 pass.

Dans une variante de réalisation, le déchargement automatique est effectué suivant la flèche B par l'ouverture 13. Dans ce cas, la grille ou plateau 17 peut ou non comporter un bord 17 b. Si la grille 17 comporte un bord 17 b, les moyens de déchargement comprennent des organes préhensifs pour soulever la barquette 19 et l'éloigner de la cellule. Si la grille 17 ne comporte pas de bord 17 b, les moyens de déchargement peuvent, par exemple comporter un tapis roulant et un levier, ou bras qui pousse la barquette 19 suivant la flèche B, le tapis roulant éloignant la barquette 19 de la cellule.In an alternative embodiment, automatic unloading is carried out along arrow B through the opening 13. In this case, the grid or tray 17 may or may not have an edge 17 b. If the grid 17 has an edge 17 b, the unloading means comprise gripping members for lifting the tray 19 and moving it away from the cell. If the grid 17 does not have an edge 17 b, the unloading means may, for example comprise a conveyor belt and a lever, or arm which pushes the tray 19 along arrow B, the conveyor belt moving the tray 19 away from the cell .

Dans les variantes de réalisation décrites ci-dessus, les moyens de cloisonnement 5 comportent des portes escamotables au passage des grilles 17 : la porte 20 escamotable dans le sens de la flèche C et la porte 12 escamotable dans le sens de la flèche D. Ces portes peuvent être constituées par des volets souples ou flexibles ou coulissant qui reviennént à leur position fermée, une fois.la grille 17 passée.In the variant embodiments described above, the partitioning means 5 comprise retractable doors when the grids 17 pass: the retractable door 20 in the direction of the arrow C and the retractable door 12 in the direction of the arrow D. These doors can be constituted by flexible or flexible or sliding shutters which return to their closed position once the grid 17 has passed.

La cellule selon l'invention peut comprendre une enceinte froide 8 ayant plus de deux parties 1 et 2.The cell according to the invention can comprise a cold enclosure 8 having more than two parts 1 and 2.

Plusieurs parties ou compartiments de froid successifs peuvent être opérants pour réaliser une séquence de traitements frigorifiques successifs en cascade présentant chacun des caractéristiques propres. Ils peuvent être séparés ou non par des parties de compartiments comme la partie 1 d'entrée qui permettent des accès aux barquettes 19 en cours de traitement frigorifique, par exemple pour ajouter un produit en cours de refroidissement.Several successive parts or compartments of cold can be operative to carry out a sequence of successive refrigeration treatments in cascade each having its own characteristics. They can be separated or not by parts of compartments such as the inlet part 1 which allow access to the trays 19 during refrigeration treatment, for example to add a product being cooled.

Dans les exemples décrits, l'utilisateur de l'armoire a plusieurs possibilités de réglage du traitement. La première possibilité consiste à jouer sur les moyens de production du froid 6 d'une manière connue, par exemple avec un thermostat régulateur réglable placé sur le circuit électrique du moto-compresseur 26. Une autre possibilité consiste à régler la vitesse de traitement en alimentant plus ou moins les moyens moteur 4 des moyens de support 3. On règle ainsi d'une part le temps de traitement frigorifique et d'autre part, la cadence d'entrée du produit traité. Une combinaison de ces deux possibilités de réglage permet, en fonction de l'agent d'échange thermique 27 choisi, d'obtenir à volonté une congélation ou une réfrigération des barquettes 19 introduites.In the examples described, the user of the cabinet has several possibilities for adjusting the treatment. The first possibility consists in playing on the means for producing the cold 6 in a known manner, for example with an adjustable regulating thermostat placed on the electric circuit of the motor-compressor 26. Another possibility consists in adjusting the treatment speed by supplying more or less the motor means 4 of the support means 3. Thus, on the one hand, the refrigeration treatment time is regulated and, on the other hand, the rate of entry of the treated product. A combination of these two adjustment possibilities makes it possible, depending on the heat exchange agent 27 chosen, to obtain freezing or refrigeration of the trays 19 introduced at will.

Dans un chargement manuel, pour que la barquette 19 ne soit pas gênée par le bord en biseau 16, les moyens de support 3 sont mis dans une position nettement en dessous de la paroi supérieure de l'enceinte 8.In manual loading, so that the tray 19 is not hampered by the bevelled edge 16, the support means 3 are placed in a position clearly below the upper wall of the enclosure 8.
