Abstract

The combination is now housed in a single, thermally insulated chamber which is equipped with (a) the evaporator of a refrigeration system which is used to cool air circulated in the chamber by a blower. (b) A freezing compartment which is permanently in communication with air delivered by the blower. (c) A cold storage compartment which can, at choice, be in open communication with the freezing compartment and blower air; alternatively, the cold storage compartment can be sealed off from the freezing zone by a removable screen. The screen is pref. in the form of a venetian blind made up of a series of slats on parallel pivot axes. The slats should all be pivoted simultaneously by a single, geared motor, pref. operated by a programmed timer. The freezing compartment is pref. located below the evaporator and air circulation blower. Used for quick freezing and cold storage of food prods. A single chamber, equipped with only a single refrigerating evaporator, is now capable of fast freezing at about -40 deg.C. followed by cold storage for long periods at -25 deg.C. This is cheaper and more compact than having to employ separate quick freezing and cold storage units.

Description

La présente invention a pour objet un appareil de surgélation et de conservation de produits alimentaires. The present invention relates to an apparatus for freezing and preserving food products.

La technique du roid est de plus en plus souvent appliquée e aux produits alimentaires tels que pttisseries et plats cuisinés, permettant la réalisation des produits de manière massive ou dans les meilleures conditions puis, leur conservation sans aucune dégradation jusqu'à la période de leur vente et de leur consommation. The technique of the roid is more and more often applied e to food products such as pttisseries and cooked dishes, allowing the realization of the products in a massive way or in the best conditions then, their conservation without any degradation until the period of their sale and their consumption.

Pour que les produits se conservent dans les meilleures conditions, sans modification de leur texture, de leur aspect iuitial, et sans dessèchement, il est avantageux de procéder en deux temps, à savoir : une surgélation suivie dune conservation. In order for the products to be preserved in the best conditions, without modification of their texture, of their hydraulic appearance, and without drying, it is advantageous to proceed in two stages, namely: freezing followed by conservation.

La surgélation consiste en une opération tres rapide de congélation à coeur du produit. Cette opération doit être réalisée dans un appareil appelé surgélateur dont la puissance frigorifique est importante, à une température basse de l'ordre de - 40 C. En fin de surgélation qui n'excède ps quelques heures, il est procédé au transfert des produits dans un conservateur à l'intérieur duquel règne une température de l'ordre de - 25 C. Freezing consists of a very rapid freezing operation at the heart of the product. This operation must be carried out in a device called deep-freezer, the refrigerating power of which is high, at a low temperature of the order of - 40 C. At the end of deep-freezing which does not exceed a few hours, the products are transferred to a preservative inside which reigns a temperature of the order of - 25 C.

Cette maçon de procéder necessite de disposer de deux appareils distincts à savoir : un surgélateur et un conservateur, imposant an investissement élevé, un coût de fonctionnement élevé puisqu'il s'agit de réaliser l'alimentation en courant de deux appareils, tout en ne pouvant pas utiliser le maximum des possibilités de ceux-ci paisque, s le conservateur fonctionne de manière permanente, le surgélateur ne travaille que de manière discontinue.  This mason to proceed requires two separate devices namely: a freezer and a preservative, imposing a high investment, a high operating cost since it is a question of realizing the current supply of two devices, while not not being able to use the maximum of these peaceful possibilities, if the conservator works permanently, the freezer works only discontinuously.

La présente invention vise a remédier à ces inconvé- nients. The present invention aims to remedy these drawbacks.

cet effet, l'appareil qu'elle concerne comprend une enceinte unique contenant
- l'évaporateur d'une installation frigorifique sur lequel passe l'air contenu dans ltenceinte soue l'action d'un ventilateur,
- un compartiment de surgélation en communication permanente avec le compartiment contenant l'évaporateur et,
- au moins un compartiment de conservation susceptible d'être mis en communication et isolé, avec le compartiment contenant l'évaporateur et le compartiment de congélation.
For this purpose, the apparatus which it relates comprises a single enclosure containing
- the evaporator of a refrigeration installation over which the air contained in the enclosure passes under the action of a fan,
- a deep-freezing compartment in permanent communication with the compartment containing the evaporator and,
- at least one storage compartment capable of being placed in communication and isolated, with the compartment containing the evaporator and the freezing compartment.

L'installation frigorifique est susceptible de plusieurs régimes de fonctionnement à savoir : au moins un régime où elle assure le maintien d'une température de conservation de tordre de - 25-C et un régime où elle procure une température de surgélation de l'ordre de - 40C, Dans la mesure où l'appareil est utilisé comme un simple conservateur, les différents compartiments qu'il comprend,à savoir le compartiment contenant l'évaporateur du groupe frigorifique, le compartiment de surgélation et les compartiments de conservation communiquent les unes avec les autres, la température étant la même, de l'ordre de - 250C dans la totalité de l'appareil. The refrigeration installation is susceptible to several operating regimes, namely: at least one regime where it maintains a twist-keeping temperature of -25-C and one regime where it provides a freezing temperature of around from - 40C, Insofar as the device is used as a simple preservative, the various compartments which it comprises, namely the compartment containing the evaporator of the refrigerating unit, the freezing compartment and the preservation compartments communicate with each other with the others, the temperature being the same, of the order of - 250C throughout the apparatus.

Dans la mesure où l'on doit surgeler des produits, les compartiments de conservation sont isolés du compartiment contenant l'évaporateur de l'installation frigorifique et du compartiment de surgélation. Les frigories a'étant alors fournies que dans le compartiment de surgélation, la température dans celui-ci atteint alors environ - 40il. En fin de période de surgélation les différents compartiments sont remis en communication de telle sorte que, compte tenu de cette nouvelle répartition, la température moyenne de l'ensemble est de tordre de - 25*C. If products have to be frozen, the storage compartments are isolated from the compartment containing the evaporator of the refrigeration system and from the freezing compartment. The frigories being then supplied only in the freezing compartment, the temperature in this one then reaches approximately - 40il. At the end of the deep-freezing period, the various compartments are put back in communication so that, taking into account this new distribution, the average temperature of the whole is twisting by - 25 ° C.

Selon une forme d'exécution de l'invention, le compartiment de surgélation est séparé du compartiment de conservation adjacent par une série de volets montés pivotants autour d'axes parallèles et susceptibles, quand ils sont sensiblement dans le prolongement les uns des autres,de former une cloison continue et quand ils sont en position inclinée, à ménager des passages entre eux. According to one embodiment of the invention, the deep-freezing compartment is separated from the adjacent storage compartment by a series of flaps mounted to pivot around parallel axes and capable, when they are substantially in line with one another, of form a continuous partition and when they are in an inclined position, to provide passages between them.

La mise en communication ou non entre le compartiment de surgélation et les compartiments de conservation adjacents est réalisée par manoeuvre des volets. The communication or not between the freezing compartment and the adjacent storage compartments is carried out by maneuvering the flaps.

Avantageusement, les moyens de commande des différents volets sont couplés et entraînés par un moto-réducteur unique lai-même commandé par une horloge de programmation du régime de fonctionnement de l'appareil. Advantageously, the control means of the various flaps are coupled and driven by a single geared motor lai itself controlled by a clock for programming the operating regime of the device.

Lorsque l'utilisateur désire surgeler une certaine quantité de produits, il lui suffît d'afficher le temps de surgélation sur l'horloge et de commander le début de la surgélation par mise en marche d'un moto-réducteur provoquant le basculement des volets assurant l'isolation du compartiment de surgélation et des compartiments adjacents de consevation. En fin de surgélation, l'horloge commande automatiquement le retour au régime de conservation initial par basculement des volets en position de mise en communication du compartiment de surgélation et des compartiments de conservation adjacents. When the user wishes to freeze a certain quantity of products, it suffices to display the freezing time on the clock and to control the start of freezing by switching on a gear motor causing the flaps to topple over ensuring insulation of the deep-freezing compartment and of the adjacent storage compartments. At the end of deep-freezing, the clock automatically controls the return to the initial conservation regime by tilting the flaps in the communication position of the deep-freezing compartment and the adjacent conservation compartments.

Avantageusement, le compartiment contenant l'évapora tour de l'installation frigorifique est situé au-dessus du compartiment de surgélation, les compartiments de conservation étant en nombre pair et superposés deux à deux l'air circulant tout d'abord dans le compartiment de surgélation puis dans les compartiments de conservation depuis celui adjacent au compartiment de surgélation jusqu'à celui adjacent au compartiment contenant l'évaporateur. Advantageously, the compartment containing the evaporator tower of the refrigeration installation is located above the deep-freezing compartment, the storage compartments being in even number and superimposed two by two the air circulating first in the deep-freezing compartment then in the storage compartments from the one adjacent to the freezing compartment to the one adjacent to the compartment containing the evaporator.

Le circuit d'air est tel que l'air passe d'abord dans le compartiment de surgélation puis successivement dans les différents compartiments de conservation avant d revenir dans le compartiment contenant l'évaporateur d'une installation frigorifique. The air circuit is such that the air first passes through the freezing compartment and then successively through the various storage compartments before returning to the compartment containing the evaporator of a refrigeration installation.

Selon une autre caractéristique de l'invention, le ventilateur de circulation d'air est monté en aval de l'évaporateur, et est agencé de telle sorte que le flux d'air soit déplacé par aspiration sur les produits contenus dans les compartiments de conservation. According to another characteristic of the invention, the air circulation fan is mounted downstream of the evaporator, and is arranged in such a way that the air flow is displaced by suction on the products contained in the storage compartments .

Le fait que l'air circule par aspiration dans les compartiments de conservation évite la formation de givre ainsi que le dessèchement des produits. The fact that the air circulates by suction in the storage compartments prevents the formation of frost as well as the drying of the products.

En outre, en amont de l'évaporateur est prévue une chicane formant piège pour la vapeur d'eau formée, éventuellement, à la fin du dégivrage. In addition, upstream of the evaporator is provided a baffle forming a trap for the water vapor formed, possibly, at the end of the defrosting.

Cette caractéristique est intéressante en ce sens que, lorsque l'on réalise le dégivrage de l'appareil, avec circulation d'air à l'intérieur de celui-ci, la vapeur d'eau contenue dans l'air est récupérée au niveau de cette chicane, évitant qu'elle ne forme, lors de l'abaissement de température à l'intérieur de l'appareil, une pellicule de glace. This characteristic is interesting in the sense that, when the device is defrosted, with air circulation inside it, the water vapor contained in the air is recovered at this baffle, preventing it from forming, when the temperature inside the appliance drops, a film of ice.

De toute façon, l'invention sera bien comprise à l'aide de la description qui suit en référence au dessin schématique annexé dont l'unique figure représente une vue en coupe longitudinale par un plan vertical de cet appareil. In any case, the invention will be clearly understood with the aid of the description which follows with reference to the appended schematic drawing, the sole figure of which represents a view in longitudinal section through a vertical plane of this device.

L'appareil représenté au dessin comprend une enceinte 2 isolée thermiquement contenant quatre compartiments, à savoir un compartiment 2 situé en haut et à gauche contenant l'évaporateur d:une installation frigorifique, un compartiment 4 situé en bas et à gauche destiné à assurer la surgélation des produits, et deux compartiments superposés respectivement 5 et 6 situés à droite, destinés à assurer la conservation des produits. The apparatus shown in the drawing comprises a thermally insulated enclosure 2 containing four compartments, namely a compartment 2 located at the top and to the left containing the evaporator d: a refrigeration installation, a compartment 4 located at the bottom and to the left intended to ensure the freezing of the products, and two superimposed compartments respectively 5 and 6 located on the right, intended to ensure the preservation of the products.

La circulation d'air à l'intérieur de l'appareil est assurée par un ventilateur 7 disposé en aval de l'évaporateur, et en~aval duquel est piacée une gaine de soufflage 8 amenant 1'air frais dans le compartiment 4 de surgélation. The air circulation inside the device is ensured by a fan 7 placed downstream of the evaporator, and downstream of which is blown a blowing duct 8 bringing fresh air into the freezing compartment 4 .

Entre le compartiment 4 et le compartiment 5 est prévue une série de volets métalliques 9 articulés autour d'axes horizontaux parallèles 10. Tous les volets 9 occupent simultanément la même position angulaire et sont actionnés à partir d'un dispositif de commande unique. La longueur des volets est telle que, lorsqu'ils sont tous en position sensiblement verticale, comme représentée en pointillés au dessin, ils forment une paroi à peu près étanche séparant les compartiments 4 et 5. Au contraire, quand ils sont dans la position représentée en traits pleins au dessin, ils ménagent des passages pour l'air entre les compartiments 4 et 5. Between the compartment 4 and the compartment 5 is provided a series of metal flaps 9 articulated around parallel horizontal axes 10. All the flaps 9 simultaneously occupy the same angular position and are actuated from a single control device. The length of the flaps is such that, when they are all in a substantially vertical position, as shown in dotted lines in the drawing, they form a roughly sealed wall separating the compartments 4 and 5. On the contrary, when they are in the position shown in solid lines in the drawing, they provide air passages between compartments 4 and 5.

Après être passé dans les compartiments 4 et 5, l'air passe dans le compartiment 6 puis, par une paroi ajourée 12, revient dans le compartiment 3 contenant l'évaporateur de l'installation frigorifique. Après passage dans la paroi ajourée 12, l'air passe dans une chicane i3 formant un piège pour les éventuelles gouttelettes de vapeur d'eau qu'il contient, en période de dégivrage. En outre, la paroi supérieure de l'enceinte 3 est revêtue d'un panneau 14 anti-condensation. Il est également prévu dans les angles de l'enceinte, des déflecteurs 15 facilitant l'écoulement du flux d'air. L'accès à chacun des compartiments 3 å 6 se fait par l'intermédiaire de portes 16.Dans les compartiments 4, 5 et 6, sont prévues des glissières 17 permettant l'engagement de plateaux ou de grilles supportant les produits devant être contenus dans l'appareil.  After passing through compartments 4 and 5, the air passes into compartment 6 and then, through an perforated wall 12, returns to compartment 3 containing the evaporator of the refrigeration installation. After passing through the perforated wall 12, the air passes through a baffle i3 forming a trap for any droplets of water vapor it contains, during the defrosting period. In addition, the upper wall of the enclosure 3 is coated with an anti-condensation panel 14. Deflectors 15 are also provided in the corners of the enclosure, facilitating the flow of the air flow. Access to each of the compartments 3 to 6 is via doors 16. In the compartments 4, 5 and 6, there are provided slides 17 allowing the engagement of trays or grids supporting the products to be contained in the device.

D1an point de vue pratiquez lorsque l'on désire surgeler une certaine quantité de produits, on place ceux-ci dans le compartiment 4, et les volets 9 sont places de manière a être sensiblement jointifs et à isoler le compartinent 4 des compartiments 5 et 6. La température dans le compartiment de surgélation atteint alors rapidement environ - 40 C. En fin de surgélation les volets sont places en position ouverte, de telle sorte que la température d'ensemble repasse à - 25 C. D1an point of view practice when you want to freeze a certain amount of products, we place these in compartment 4, and the flaps 9 are placed so as to be substantially contiguous and to isolate compartment 4 of compartments 5 and 6 The temperature in the freezer compartment then quickly reaches around - 40 C. At the end of freezing, the flaps are placed in the open position, so that the overall temperature returns to - 25 C.

Comme il ressort de ce qui précède, l'invention apporte une grande amélioration à la technique existante en fournissant un appareil susceptible à partir d'une installation frigorifique unique et d'une enceinte unique, d'assurer à la fois la surgélation et la conservation de produits alimentaires, tout en étant d'une utilisation très pratique et d'une réalisation économique. As is apparent from the above, the invention brings a great improvement to the existing technique by providing a device capable, from a single refrigeration installation and a single enclosure, of ensuring both freezing and preservation of food products, while being very practical to use and economical.

Comme il va de soi, l'invention ne se limite pas à la seule forme d'exéoution de cet appareil,décrite ci-dessus à titre d'exemple, elle en embrasse, au contraire, toutes les variantes de réalisation. It goes without saying that the invention is not limited to the sole form of execution of this device, described above by way of example, on the contrary, it embraces all of the variant embodiments thereof.

C'est ainsi notamment que l'appareil pourrait comprendre un nombre de compartiments de conservation supérieur à deux, par exemple quatre, six ou huit, la circulation de l'air se faisant successivement dans les différents compartiments depuis le compartiment de surgélation vers le compartiment contenant l'évaporateur de l'installation frigorifique sans que l'on sorte pour autant du cadre de l'invention, ou que la position relative de la case de surgélation et des cases de conservation pourrait être inversée, le flux d'air se trouvant lui-même inversé.  Thus, in particular, the appliance could include a number of storage compartments greater than two, for example four, six or eight, the air circulation being successively carried out in the various compartments from the freezing compartment to the compartment. containing the evaporator of the refrigeration installation without departing from the scope of the invention, or without the relative position of the freezing box and the storage boxes being able to be reversed, the air flow being itself reversed.
