Description

L'invention concerne une installation de surgélation et de conservation des produits alimentaires. The invention relates to an installation for freezing and preserving food products.

L'objet de l'invention se rattache au secteur technique des installations frigorifiques en général. Plus particulièrement, l'invention s'applique à la surgélation et à la conservation des produits de boulangerie, de pâtisserie, de charcuterie et de traiteurs. The object of the invention relates to the technical sector of refrigeration installations in general. More particularly, the invention applies to the freezing and storage of bakery, pastry, cold cuts and catered products.

I1 est bien connu que les boulangers, les pâtissiers et autres doivent préparer à l'avance leurs produits (gâteaux, glaces, entremets, plats préparés, ...), puis ces produits doivent être conservés dans les meilleurs conditions possibles d' hygiène et de qualité en accord avec les règlements sanitaires, en attendant d'être présentés à la vente, après éventuellement une finition de surface. It is well known that bakers, pastry chefs and others must prepare their products in advance (cakes, ice cream, desserts, ready meals, ...), then these products must be stored in the best possible hygienic conditions and quality in accordance with health regulations, pending presentation for sale, possibly after a surface finish.

Pour cela, il existe sur le marché des appareils frigorifiques assurant une surgélation rapide des produits à moins 35"C environ, puis une conservation des produits surgelés à moins 20 C environ. Avec ce type d'appareil, le professionnel peut ainsi régulariser sa production en préparant ses produits pendant les heures creuses, ce qui permet d'aménager les horaires de travail. For this, there are refrigeration devices on the market ensuring rapid freezing of products at around 35 "C, then conservation of frozen products at around 20 C. With this type of device, the professional can thus regulate his production by preparing its products during off-peak hours, which allows flexible working hours.

Cependant, ces appareils ne rendent pas tous les services que l'on est en droit d'attendre, et ils sontonéreux.  However, these devices do not provide all the services that one has the right to expect, and they are expensive.

En effet, certaines installations sont équipées de plusieurs groupes frigorifiques et de compartiments séparés, avec une ventilation insuffisante et inadaptée, ce qui nuit à la bonne conservation du goût des produits. Indeed, some installations are equipped with several refrigeration units and separate compartments, with insufficient and unsuitable ventilation, which affects the good preservation of the taste of the products.

D'autres installations utilisent des ventilateurs auxiliaires pour assurer le passage de l'air entre le compartiment surgélation et le ou les compartiments de conservation. Mais dans ce cas des phénomènes de givrage dénaturent les produits et empêchent de le terminer en surface. D'autre part, la ventilation est trop importante en partie conservation, dtoù dessèchement des produits. Other installations use auxiliary fans to ensure the passage of air between the deep-freezing compartment and the storage compartment (s). But in this case, frosting phenomena distort the products and prevent them from finishing on the surface. On the other hand, the ventilation is too important in part conservation, from where drying of the products.

A noter encore que lors de l'ouverture des portes en vue des transferts, le ou les groupes frigorifiques continuent à fonctionner et aspirent de l'air ambiant humide qui réchauffe l'air intérieur, avec tous les inconvénients que cela suppose. It should also be noted that when the doors are opened for transfers, the refrigeration unit (s) continue to operate and draw in humid ambient air which heats the indoor air, with all the drawbacks that this implies.

L'installation suivant l'invention remédie à ces in convénients et apporte de nombreux avantages, en ce sens qu'elle est économique à fabriquer et dans son fonctionnement, quelle assure une répartition optimum du froid sur les produits sans production de givre et autres phénomènes de nature à diminuer voire à détuire la qualité des produits qu'elle contient. The installation according to the invention remedies these disadvantages and brings numerous advantages, in the sense that it is economical to manufacture and in its operation, which ensures optimum distribution of the cold on the products without production of frost and other phenomena. likely to decrease or even destroy the quality of the products it contains.

Suivant une première caractéristique, l'installation est composée d'une enceinte comprenant un compartiment de surgélation équipé d'un seul groupe frigorifique avec un compresseur, un évaporateur et un ventilateur, et un ou plusieurs compartiments de conservation, communiquant entre eux et avec le compartirne.nt de surgélation par des ouvertures appropriées réalisées dans des cloisons ; une plaque déflectrice est interposée entre le groupe frigorifique et la cloison séparant le compartiment de surgélation du premier compartiment de conservation, pour retenir le givre en sortie de ventilateur et dévier l'air vers le bas, tandis que les ouvertures de circulation d'air à travers la cloison de séparation entre le compartiment de surgélation et le compartiment de conservation, sont équipées de moyens d'obturation étanche pour certaines phases de fonctionnement. According to a first characteristic, the installation is composed of an enclosure comprising a deep-freezing compartment equipped with a single refrigeration unit with a compressor, an evaporator and a fan, and one or more preservation compartments, communicating with each other and with the compartment freezing by suitable openings made in partitions; a deflector plate is interposed between the refrigeration unit and the partition separating the freezing compartment from the first preservation compartment, to retain the frost at the fan outlet and deflect the air downwards, while the air circulation openings at through the partition between the freezing compartment and the storage compartment, are equipped with sealing means for certain operating phases.

Ces caractéristiques et d'autres encore ressortiront de la description qui suit. These characteristics and others will emerge from the description which follows.

Pour fixer l'objet de l'invention, sans toutefois le limiter, dans le dessin annexé :
Les figures 1 et 2 sont des vues schématiques de face et en coupe illustrant respectivement llinstallation en phase de surgélation et en phase de conservation.
To fix the subject of the invention, without however limiting it, in the appended drawing:
Figures 1 and 2 are schematic front views and in section illustrating respectively the installation in the deep-freezing phase and in the conservation phase.

La figure 3 est une vue schématique en plan et en coupe de l'installation selon figures 1 et 2. FIG. 3 is a schematic plan view and in section of the installation according to FIGS. 1 and 2.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant sous des formes non limitatives de réalisation illustrées schématiquement aux figures du dessin. In order to make the object of the invention more concrete, it is now described in nonlimiting embodiments illustrated schematically in the figures of the drawing.

L'installation comprend une enceinte isolante (1) séparée dans la longueur en plusieurs compartiments. Dans l'exem- ple illustré l'enceinte présente un compartiment (A) dit de surgélation, et deux compartinents (B, C) dits de conservation. The installation comprises an insulating enclosure (1) separated lengthwise into several compartments. In the example illustrated, the enclosure has a compartment (A) called deep-freezing, and two compartments (B, C) known as storage.

Tous les compartiments sont équipés de glissières (2) ou autres moyens analogues permettant les manipulations et le positionnement de plaques ou de grilles (3) destinées à recevoir les produits à surgeler et à corsfrver, et étudiées pour la circulation d'air. All the compartments are fitted with slides (2) or other similar means allowing the handling and positioning of plates or grids (3) intended to receive the products to be frozen and to be frozen, and designed for the circulation of air.

Le compartiment de surgélation présente en façade au moins une porte d'accès (4), tandis que le ourles compartiments de conservation présentent chacun de préférence deux portillons d'accès (5). The freezing compartment has at least one access door (4) on the front, while the storage compartments each preferably have two access doors (5).

Ces portes et portillons sont bien entendu isolantes et étanches.et, selon une des caractéristiques de l'invention, elles sont équipées de contacteurs (6) reliés au groupe frigorifique afin d'obtenir son arrêt automatique lors de l'ouverture, avec une temporisation de redémarrage règlable à volonté. These doors and gates are of course insulating and waterproof. And, according to one of the characteristics of the invention, they are fitted with contactors (6) connected to the refrigeration unit in order to obtain its automatic stop during opening, with a time delay. restart adjustment adjustable at will.

Par cette disposition, on évite ainsi tout risque d' aspiration d'air ambiant dans l'enceinte préjudiciable à l'ef- ficacité de l'installation. This arrangement thus avoids any risk of aspiration of ambient air into the enclosure which is detrimental to the efficiency of the installation.

En variante, au lieu des contacteurs, on peut prévoir dans chaque compartiment des cellules sensibles à la lumière pour arrêter le groupe frigorifique dès l'ouverture d'une porte. Alternatively, instead of the contactors, cells sensitive to light can be provided in each compartment to stop the refrigeration unit as soon as a door is opened.

Le groupe frigorifique comprend de manière connue un compresseur (7) placé de préférence en dehors du local afin d' éviter les désagréments du bruit et de la chaleur, un évaporateur (8) et un ventilateur (9) disposés en partie haute du compartiment de surgélation, au-dessus des plaques (3). The refrigeration unit comprises in known manner a compressor (7) preferably placed outside the room in order to avoid the annoyances of noise and heat, an evaporator (8) and a fan (9) arranged in the upper part of the compartment. deep freezing, above the plates (3).

Une cloison isolante (10) sépare le compartiment de surgélation du premier compartiment de conservation, et on interpose entre la cloison (10) et le ventilateur (9) une plaque isolante (11) limitée en hauteur à la zâne d'action dudit ventilateur et destinée à retenir le givre en sortie de ventilate-lr et à dévier l'air vers le bas. An insulating partition (10) separates the freezing compartment from the first preservation compartment, and an insulating plate (11) is interposed between the partition (10) and the ventilator (9) limited in height to the action zone of said ventilator and intended to retain the frost at the outlet of ventilate-lr and to deflect the air downwards.

L'expérience démontre que la plaque (11) doit être fixée approximativement au milieu de la distance séparant le ventilateur de la cloison, pour obtenir les meilleurs résultats, c' est-à-dire recueillir et "piéger" un maximum de givre. Bien entendu, il n'est pas exclu de prévoir une fixation règlable de la plaque (11) pour faire varier sa position en fonction des besoins. Experience shows that the plate (11) must be fixed approximately in the middle of the distance separating the fan from the partition, to obtain the best results, that is to say to collect and "trap" a maximum of frost. Of course, it is not excluded to provide an adjustable fixing of the plate (11) to vary its position as needed.

Les compartiments de conservation présentent des montants (12) destinés à la fixation des glissières (2), et la cloison (10) présente des ouvertures supérieures (10a) et inférieures (lob) de passage de l'air (selon Zes flèches de la figure 2). The storage compartments have uprights (12) intended for fixing the slides (2), and the partition (10) has upper (10a) and lower (lob) air passage openings (according to the arrows of the figure 2).

Selon une des caractéristiques de l'invention, 3 f.-s ou- vertures (lova - lOb) de la cloison (10) doivent être obturées de manière étanche pendant la phase de surgélation afin d'obtenir une circulation d'air uniquement dans le compartiment (A), tandis que pendant la phase de conservation, l'air doit traverser chaque compartiment de conservation (B, C...). According to one of the characteristics of the invention, 3 openings (lova - lOb) of the partition (10) must be sealed during the freezing phase in order to obtain air circulation only in compartment (A), while during the conservation phase, air must pass through each conservation compartment (B, C ...).

Pour cela, on peut utiliser différents moyens coulissants ou oscillants d'obturation. On a illustré ici non limitativement un dispositif comprenant des volets isolants (13 et 14) qui sont articulés par une extrémité sur la cloison (10), de manière à ce que leur extrémité opposée, conformée pour obtenir une obturation étanche, s'appuie respectivement sur la face inférieure de la plaque (11) et sur le fond de l'enceinte. For this, different sliding or oscillating shutter means can be used. Illustrated here without limitation a device comprising insulating flaps (13 and 14) which are articulated by one end on the partition (10), so that their opposite end, shaped to obtain a sealed closure, is supported respectively on the underside of the plate (11) and on the bottom of the enclosure.

Bien entendu, ces volets sont de préférence manoeuvrés automatiquement et en synchronisme, par tous moyens mécaniques, électromécaniques ou similaires, reliés à une minuterie ou équivalent, pour être ouverts lorsque le temps de surgélation est atteint. Of course, these flaps are preferably operated automatically and in synchronism, by any mechanical, electromechanical or similar means, connected to a timer or equivalent, to be opened when the freezing time is reached.

Dans l'exemple illustré, les volets sont articulés à des biellettes (15) elles-mêmes articulées à un palonnier (16) commandé par un organe moteur du type servo-moteur (17) par exemple. In the example illustrated, the flaps are articulated with rods (15) which are themselves articulated with a lifting beam (16) controlled by a motor member of the servo-motor type (17) for example.

On comprend que lorsque les produits à surgeler ont -été introduits dans le compartiment surgélation, les volets sont placés en position d'obturation, et le groupe frigorifique est actionné pour amener la température des produits à moins 40"C environ, en les déshumidifiant par circulation de l'air à grande vitesse uniquement dans le compartiment de surgélation. L'air humide traverse l'évaporateur (8) et est projeté par le ventilateur sur la plaque déflectrice (11) pour être dévié vers le bas et remonter vers l'évaporateur en traversant les grilles porte-produits (figure 1). Les gouttes d'eau résiduelles sont récupérées dans l'évaporateur. Ainsi, progressivement, l'air se déshumidifie à chaque passage dans l'évaporateur. It is understood that when the products to be deep-frozen have been introduced into the deep-freezing compartment, the flaps are placed in the closed position, and the refrigeration unit is actuated to bring the temperature of the products to at least 40 "C, by dehumidifying them by air circulation at high speed only in the deep-freezing compartment. The humid air passes through the evaporator (8) and is projected by the fan on the deflector plate (11) to be deflected down and up towards the evaporator through the product holder grids (figure 1). The residual drops of water are collected in the evaporator, so that the air gradually dehumidifies with each pass through the evaporator.

Lorsque la température de surgélation est atteinte, la minuterie commande l'ouverture simultanée des volets et une partie de 1 air dévié par la plaque (11) peut passer à vitesse lente (pour ne pas dessécher les produits) par les ouvertures (lova), pour revenir dans le compartiment de surgélation par les ouvertures (lob) , comme illustré à la figure 2. When the freezing temperature is reached, the timer controls the simultaneous opening of the shutters and part of the air deflected by the plate (11) can pass at slow speed (so as not to dry out the products) through the openings (lova), to return to the freezer compartment through the openings (lob), as illustrated in Figure 2.

Les produits surgelés sont placés dans le ou les com partiments de conservation où donc périodiquement ils seront traversés par l'air déshumidifié en provenance du compartiemnt de surgélation, pour être conservés à une température d'environ moins 20"C.  The frozen products are placed in the storage compartment or compartments where, therefore, periodically they will be traversed by the dehumidified air coming from the freezing compartment, to be stored at a temperature of approximately minus 20 "C.

A noter que l'on fonctionne avec une plage de température restreinte grâce à une régulation par thermostat électronique, cela pour assurer la bonne tenue des produits. Note that we operate with a limited temperature range thanks to an electronic thermostat control, this to ensure the good performance of the products.

Les avantages ressortent bien de la description, on souligne encore - La répartition parfaite du froid sur les produits par la circulation d'air. The advantages emerge clearly from the description, it is emphasized again - The perfect distribution of the cold on the products by the air circulation.

- L'absence de givre sur les produits après transfert du compartiment de surgélation au compartiment de conservation, par la déshumidification de l'air.- The absence of frost on the products after transfer from the freezing compartment to the preservation compartment, by dehumidifying the air.

- L'arrêt automatique du groupe frigorifique avec temporisation de redémarrage à chaque ouverture de portes, annulant les risques d'aspiration d'air chaud du local.- Automatic shutdown of the refrigeration unit with restart delay each time the doors are opened, eliminating the risk of hot air being drawn from the room.

- L'économie de fabrication et de consommation d'énergie par l'utilisation d'un seul groupe frigorifique.- The economy of manufacturing and energy consumption by the use of a single refrigeration unit.

L'invention ne se limite aucunement à celui de ses modes d'application non plus qu'à ceux des modes de réalisation de ses diverses parties ayant plus spécialement été indiquées elle en embrasse au contraire toutes les variantes.  The invention is in no way limited to that of its modes of application any more than to those of the embodiments of its various parts having been more particularly indicated, on the contrary it embraces all variants.
