Description

L'invention se rapporte à un dispositif de réfrigération et de séchage de produits consommables sensibles aux chocs et/ou à la compression. The invention relates to a device for refrigerating and drying consumable products sensitive to shocks and / or compression.

Le dispositif de l'invention convient pour le traitement de végétaux consommables tels les feuilles de salade mais egalement pour les produits carnes tels des foies de volailles. The device of the invention is suitable for the treatment of consumable plants such as salad leaves but also for meat products such as poultry livers.

Avant d'être réfrigérées à la a température d'entreposage pour leur exposition à la vente dans des vitrines réfrigérées, les produits consommables sont généralement lavés. Before being refrigerated at storage temperature for display in refrigerated display cases, consumables are usually washed.

En dépit d'un essorage et/ou d'un égouttage minutieux, les produits considérés retiennent à leur surface une certaine quantité d'eau, laquelle peut nuire à leur présentation notamment lorsqu'elle décante dans l'emballage desdits produits après leur transport et/ou leur stockage en vitrine. Despite careful spinning and / or draining, the products in question retain a certain amount of water on their surface, which can affect their presentation, in particular when it settles in the packaging of said products after transport and / or their storage in a display case.

Un résultat que l'invention vise à obtenir est un dispositif de réfrigération et de séchage de produits consommables qui remédie à l'inconvénient précité. A result which the invention aims to obtain is a device for refrigerating and drying consumable products which overcomes the aforementioned drawback.

A cet effet l'invention a pour objet un dispositif notamment caractérisé en ce que le moyen de déplacement des produits consommables à travers l'enceinte réfrigéree qu'il comporte consiste en un support qui, présentant une surface inclinée, est associé à un moyen générateur d'un mouvement vibratoire de nature à engendrer la progression des produits sur le support vers l'ouverture de sortie de l'enceinte. To this end, the subject of the invention is a device notably characterized in that the means for moving the consumable products through the refrigerated enclosure which it comprises consists of a support which, having an inclined surface, is associated with a generating means. a vibratory movement such as to generate the progression of the products on the support towards the outlet opening of the enclosure.

L'invention sera bien comprise à la lecture de la description ci-après faite à titre d'exemple non limitatif en regard du dessin ci-annexé qui représente une vue schématique du dispositif en coupe selon un plan vertical. The invention will be clearly understood on reading the description below given by way of nonlimiting example with reference to the attached drawing which represents a schematic view of the device in section along a vertical plane.

En se reportant au dessin, on voit un dispositif 1 de réfrigération et de séchage de produits 2 consommables notamment sensibles aux chocs et/ou à la compression. Referring to the drawing, there is seen a device 1 for refrigerating and drying consumable products 2, in particular sensitive to shocks and / or compression.

Le dispositif comprend essentellement :
- une enceinte 3 qui, destinée à confiner une atmosphère gazeuse 4 pour la réfrigération et le séchage des produits 2, doit être traversée par lesdits produits en un temps déterminé,
- un moyen 5 de déplacement des produits dans l'enceinte selon une trajectoire et une vitesse prédéterminées et ce au moins entre une ouverture d'entrée 6 et une ouverture de sortie 7 que comprend ladite enceinte,
- un moyen 8 de séchage et de réfrigération d'un fluide gazeux 9 (symbolisé par une fleche) tel de l'air destiné à constituer l'atmosphère de l'enceinte 3,
- un moyen 10 d'insufflation dans l'enceinte 3 du fluide gazeux 9 préparé par le moyen 8 précité,
- un moyen 12 d'extraction du fluide gazeux distribué dans l'enceinte 3.The device essentially comprises:
an enclosure 3 which, intended to confine a gaseous atmosphere 4 for the refrigeration and drying of the products 2, must be crossed by the said products in a determined time,
a means 5 for moving the products in the enclosure according to a predetermined trajectory and speed and this at least between an inlet opening 6 and an outlet opening 7 which said enclosure comprises,
a means 8 for drying and refrigerating a gaseous fluid 9 (symbolized by an arrow) such as air intended to constitute the atmosphere of the enclosure 3,
a means 10 for insufflation into the enclosure 3 of the gaseous fluid 9 prepared by the above-mentioned means 8,
a means 12 for extracting the gaseous fluid distributed in the enclosure 3.

Le sens de progression des produits dans l'enceinte 4, implicite compte tenu de la position de l'ouverture d'entrée est purement arbitraire et non limitatif. The direction of progression of the products in enclosure 4, implicit in view of the position of the inlet opening, is purely arbitrary and not limiting.

Conformément à l'invention, le moyen 5 de déplacement des produits 2 à travers l'atmosphère gazeuse 4 de l'enceinte 3 consiste en un support 13 qui, présentant une surface inclinée 14 est associé à un moyen 15 générateur d'un mouvement vibratoire de nature à engendrer la progression des produits sur le support vers l'ouverture de sortie de l'enceinte. According to the invention, the means 5 for moving the products 2 through the gaseous atmosphere 4 of the enclosure 3 consists of a support 13 which, having an inclined surface 14 is associated with a means 15 generating a vibratory movement likely to cause the progression of the products on the support towards the exit opening of the enclosure.

Selon l'invention, le support 13 est conformé en une rampe sensiblement hélicoîdale.  According to the invention, the support 13 is shaped as a substantially helical ramp.

Suivant l'invention, d'une part, la surface inclinée 14 du support 13 est dotée de perforations 16 et, d'autre part, ces perforations débouchent en regard d'au moins une gouttière 17 de collecte de tout liquide qui franchit lesdites perforations. According to the invention, on the one hand, the inclined surface 14 of the support 13 is provided with perforations 16 and, on the other hand, these perforations open opposite at least one gutter 17 for collecting any liquid which crosses said perforations .

De préférence la gouttière 17 évacue le liquide recueilli hors de l'enceinte. Preferably, the gutter 17 evacuates the liquid collected outside the enclosure.

La gouttière 17 a été représentée symboliquement par un trait mixte fort. The gutter 17 has been symbolically represented by a strong mixed line.

Le résultat essentiel visé par l'invention est obtenu essentiellement par la a mise en oeuvre des moyens qui viennent d'être décrits. The essential result targeted by the invention is obtained essentially by the use of the means which have just been described.

Précisément le fait de déplacer les produits 2 dans l'enceinte sur une surface incline et au moyen de vibrations permet d'optimiser le sechage des produits puisque l'action de vibration se combine à l'action du fluide réfrigéré pour chasser le liquide qui recouvre les produits, lequel liquide est rapidement évacué du fait de l'inclinaison du support et des perforations annoncées. Precisely the fact of moving the products 2 in the enclosure on an inclined surface and by means of vibrations makes it possible to optimize the drying of the products since the action of vibration combines with the action of the refrigerated fluid to expel the liquid which covers the products, which liquid is quickly evacuated due to the inclination of the support and the announced perforations.

Dans une forme préférée de réalisation, le moyen 8 de séchage et de réfrigération du fluide gazeux 9 comprend, d'une part, un evaporateur de fluide frigorigène au contact duquel on fait circuler le fluide gazeux pour induire la condensation de son eau et, d'autre part, un élément de chauffage thermo-latéral, tel un radiateur, au contact duquel on fait circuler le fluide gazeux deshydraté pour, en quelque sorte, réchauffer ce fluide et ajuster sa temperature à celle requise dans l'enceinte de réfrigération. In a preferred embodiment, the means 8 for drying and refrigerating the gaseous fluid 9 comprises, on the one hand, a refrigerant evaporator in contact with which the gaseous fluid is circulated to induce the condensation of its water and, d on the other hand, a thermo-lateral heating element, such as a radiator, in contact with which the dehydrated gaseous fluid is circulated in order, in a way, to heat this fluid and adjust its temperature to that required in the refrigeration chamber.

Le fluide gazeux 9 est également canalisé à travers des filtres anti-bactéries.  The gaseous fluid 9 is also channeled through anti-bacteria filters.
