Abstract
Description
La présente invention concerne une installation de déshydratation utilisant plus particulièrement des zéolithes comme moyens d'adsorption. L'invention est notamment destinée à la déshydratation de produits alimentaires dont les qualités organoleptiques doivent être conservées.The present invention relates to a dehydration plant using more particularly zeolites as adsorption means. The invention is particularly intended for the dehydration of food products whose organoleptic qualities must be preserved.
On rappelle qu'une zéolithe est un matériau comportant des pores de diamètre supérieur à la plus petite dimension d'une molécule d'eau et des charges électriques attirant les molécules d'eau. Ces caractéristiques confèrent à la zéolithe un pouvoir d'adsorption de l'eau intéressant dans le domaine de la déshydratation.It is recalled that a zeolite is a material comprising pores with a diameter greater than the smallest dimension of a water molecule and electrical charges attracting water molecules. These characteristics give the zeolite a water adsorption power of interest in the field of dehydration.
La déshydratation au moyen de zéolithes, ou "zéodratation", est généralement réalisée au moyen d'une installation comportant une première enceinte et une deuxième enceinte attenantes et en communication l'une avec l'autre. La première enceinte est agencée pour recevoir des produits à déshydrater et la deuxième enceinte reçoit des zéolithes et est équipée d'une pompe d'aspiration d'air contenu dans les enceintes. La pompe d'aspiration crée une dépression dans les enceintes qui favorise l'évaporation de l'eau contenu dans les produits qui sont éventuellement chauffés. La vapeur d'eau passe dans la deuxième enceinte ou elle est piégée dans les zéolithes. Ce type de déshydratation est particulièrement efficace, voir par exemple
Toutefois, une partie des arômes est quand même extraite des produits. Ces arômes se retrouvent dans la deuxième enceinte avant d'en être évacués par la pompe. Il en résulte une altération des qualités organoleptiques des produits déshydratés.However, some of the aromas are still extracted from the products. These flavors are found in the second chamber before being removed by the pump. This results in an alteration of the organoleptic qualities of dehydrated products.
Un but de l'invention est de proposer un moyen de déshydratation de produits, en particulier de produits alimentaires, qui soit efficace tout en n'occasionnant qu'une altération minimum des qualités organoleptiques des produits.An object of the invention is to provide a dehydration means for products, in particular food products, which is effective while not causing damage. that a minimum alteration of the organoleptic qualities of the products.
A cet effet, on prévoit, selon l'invention, une installation de déshydratation de produits, selon la revendication 1.For this purpose, according to the invention, a product dehydration plant according to
Les arômes qui s'échapperaient des produits lors de l'évaporation de l'eau contenu dans les produits ne peuvent passer au travers des zéolithes. Ces arômes ne peuvent s'échapper du compartiment et restent confinés au voisinage des produits. La destruction d'arômes est de la sorte limitée. Les zéolithes assurent ainsi leur fonction d'adsorption des molécules d'eau tout en constituant un barrage pour les arômes.Flavors that escape from the products during the evaporation of the water contained in the products can not pass through the zeolites. These flavors can not escape from the compartment and remain confined to the vicinity of the products. The destruction of aromas is thus limited. Zeolites thus ensure their adsorption function of water molecules while constituting a barrier for aroma.
Selon un mode de réalisation particulier, la paroi formée par la couche de moyens d'adsorption est la paroi supérieure et cette paroi comprend un plateau ayant un fond perméable à l'air et à la vapeur d'eau.According to a particular embodiment, the wall formed by the layer of adsorption means is the upper wall and this wall comprises a plate having a bottom permeable to air and water vapor.
Ce mode de réalisation est particulièrement simple et assure une évacuation optimale de l'air et de la vapeur d'eau.This embodiment is particularly simple and ensures optimal evacuation of air and water vapor.
Avantageusement, le compartiment comprend une paroi inférieure également formée par une couche de moyens d'adsorption.Advantageously, the compartment comprises a lower wall also formed by a layer of adsorption means.
L'efficacité de l'installation est ainsi encore améliorée.The efficiency of the installation is thus further improved.
De préférence, la paroi supérieure du compartiment est réglable en hauteur et le réceptacle comprend avantageusement des parois latérales destinées à venir en appui contre le fond du plateau formant la paroi supérieure du compartiment.Preferably, the upper wall of the compartment is adjustable in height and the receptacle advantageously comprises side walls intended to bear against the bottom of the plate forming the upper wall compartment.
Ceci permet d'amener la couche de moyens d'adsorption au plus près des produits et de confiner les arômes au plus près des produits.This makes it possible to bring the layer of adsorption means closer to the products and to confine the aromas closer to the products.
Selon une caractéristique particulière, l'installation comprend un moyen de réchauffage du réceptacle à produits.According to a particular characteristic, the installation comprises a means of heating the product receptacle.
On évite ainsi que l'évaporation de l'eau ne produise un refroidissement des produits qui serait préjudiciable à leurs qualités.This prevents the evaporation of the water from producing a cooling of the products which would be detrimental to their qualities.
De préférence alors, les moyens d'adsorption produisant un dégagement de chaleur lors de l'adsorption d'eau, les moyens d'adsorption sont agencés de telle manière que le dégagement de chaleur contribue au réchauffement des produits.Preferably, the adsorption means producing a release of heat during the adsorption of water, the adsorption means are arranged in such a way that the release of heat contributes to the warming of the products.
Le dégagement de chaleur peut être communiqué aux produits par conduction et rayonnement. Le réchauffage ne nécessite pas d'apport d'énergie extérieure, ce qui rend l'installation de l'invention relativement économe en énergie.The release of heat can be communicated to the products by conduction and radiation. Reheating does not require external energy input, which makes the installation of the invention relatively energy efficient.
D'autres caractéristiques et avantages de l'invention ressortiront à la lecture de la description qui suit d'un mode de réalisation particulier non limitatif de l'invention.Other features and advantages of the invention will become apparent on reading the following description of a particular non-limiting embodiment of the invention.

Un module généralement désigné en 5 de support de produits à déshydrater et de zéolithes est reçu dans l'enceinte 1. Ce module 5 comprend ici deux parois latérales 6 entre lesquelles sont fixés des paires de plateaux 7.a, 8.a ; 7.b, 8.b ; 7.c, 8.c horizontaux.A module generally designated 5 de product support to be dehydrated and zeolites is received in the

Chaque plateau 7 est ici rigidement fixé aux parois latérales 6 tandis que le plateau 8 correspondant s'étend au-dessus et à distance du plateau 7 concerné et est relié aux parois latérales 6 par des glissières 13 réglables en hauteur de manière connue en elle-même. Le plateau 8 d'une paire est également espacé du plateau 7 de la paire de plateaux adjacente.Each plate 7 is here rigidly fixed to the
Les parois latérales 6 présentent des lumières 29 qui s'étendent en regard de chaque espace existant entre le bords libre des parois latérales 9 du plateau 8 d'une paire de plateaux et le fond 10 du plateau 7 de la paire adjacente.The
A l'intérieur de chaque plateau 7, 8 s'étend un serpentin 14. Les serpentins 14 sont reliés les uns aux autres par une conduite 15 pour former un circuit de transport d'un fluide caloporteur. Les conduites 15 sont souples ou de longueur variable pour ne pas entraver les mouvements des plateaux 8. Les serpentins 14 se trouvant aux extrémités de ce circuit sont reliés à un organe de régulation thermique 16 assurant de manière connue en elle-même la propulsion du fluide caloporteur dans le circuit et le refroidissement dudit fluide.Inside each plate 7, 8 extends a
Les plateaux 7, 8 reçoivent des zéolithes 17. La grille 12 possède des mailles retenant les zéolithes 17. La grille 12 permet le passage de l'air et de la vapeur d'eau.The trays 7, 8 receive
Un plateau 18 destiné à recevoir les produits à déshydrater est reçu entre les plateaux 7, 8 de chaque paire de plateaux. Le plateau 18 comprend un fond 19 et des parois latérales 20 percées d'ouvertures 21.A
Chaque plateau 18 est reçu sur des glissières 22 coulissantes en contact avec les zéolithes 17 du plateau 7 au-dessus duquel il est monté. Les glissières 22 et le plateau 18 sont en matériau conducteur thermiquement de manière à établir une relation d'échange thermique entre les produits contenus dans le plateau 18 et ces zéolithes 17. En variante, les glissières 22 peuvent être fixes.Each
Le fonctionnement de l'installation va maintenant être décrit.The operation of the installation will now be described.
Après chargement des plateaux 18 en produits à déshydrater, chaque plateau 18 est mis en place entre la paire correspondante de plateaux 7, 8. Le plateau 8 est alors abaissé de manière que le fond 10 de celui-ci vienne en contact des bords libres des parois latérales 20 des plateaux 18.After loading the
Chaque paire de plateaux 7, 8, le plateau 18 correspondant et les parois latérales 6 forment un compartiment.Each pair of trays 7, 8, the
La porte 3 est ensuite refermée et la pompe d'aspiration des moyens de mise sous vide 4 est mise en fonctionnement.The
L'air est alors aspiré dans l'enceinte 1. L'air s'échappe des plateaux 18 principalement par l'ouverture supérieure de ceux-ci et par l'ouverture 11 du fond 10 des plateaux 8 avant de traverser les zéolithes 17 pour se s'écouler dans l'espace séparant les paires de plateaux. L'air s'échappe également par les ouvertures 21 des parois latérales 20 des plateaux 18 avant de passer au travers des zéolithes 17 des et des ouvertures 11 des plateaux 7 pour s'écouler dans l'espace séparant les paires de plateaux.The air is then sucked into the
L'air s'écoule hors de l'espace séparant les paires de plateaux par les lumières 29 des parois latérales 6 et est évacué hors de l'enceinte par la pompe des moyens de mise sous vide 4.The air flows out of the space between the pairs of trays by the
La pression dans l'enceinte 1 diminuant, l'eau contenu dans les produits s'évapore. La vapeur d'eau ainsi créée suit le même trajet que l'air jusqu'aux zéolithes dans les pores desquelles elle est piégée.As the pressure in the
Les produits sont ainsi progressivement déshydratés.The products are thus progressively dehydrated.
On notera que l'air du compartiment est aspiré au travers des zéolithes de sorte que la plupart des arômes ne peuvent s'échapper du compartiment, les zéolithes limitant le passage de ceux-ci vers l'extérieur du compartiment. Comme les zéolithes sont très proches des produits, les arômes sont donc maintenus au voisinage des produits.It will be noted that the air of the compartment is sucked through the zeolites so that most of the aromas can not escape from the compartment, the zeolites limiting the passage of these to the outside of the compartment. As the zeolites are very close to the products, the aromas are therefore maintained in the vicinity of the products.
L'adsorption de l'eau engendre une élévation de température des zéolithes 17. La chaleur engendrée au niveau des zéolithes 17 du plateau 8 est communiquée aux produits par rayonnement. La chaleur engendrée au niveau des zéolithes 17 du plateau 7 est communiquée aux produits par conduction via les glissières 22 et le plateau 18.The adsorption of the water causes a temperature rise of the
Le réchauffement des produits permet d'augmenter l'évaporation de l'eau. Ce réchauffement est contrôlé par l'intermédiaire de l'organe de régulation thermique 16 en fonction des informations fournies par des capteurs de température non représentés disséminés dans le module 5.The warming of the products makes it possible to increase the evaporation of the water. This heating is controlled via the
Il est également possible d'utiliser l'organe de régulation thermique pour entretenir une différence de température entre les produits et l'environnement immédiat de ceux-ci. Par exemple, on peut maintenir une température de 20° au niveau des produits et de 70° aux voisinage de celui-ci. Cette différence de température provoque une condensation sur les produits des arômes qui sont maintenus dans le compartiment.It is also possible to use the thermal regulator to maintain a temperature difference between the products and the immediate environment thereof. For example, a temperature of 20 ° at the product level and 70 ° at the vicinity of the product can be maintained. This difference in temperature causes condensation on the products of the aromas that are maintained in the compartment.
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et on peut y apporter des variantes de réalisation sans sortir du cadre de l'invention tel que défini par les revendications.Of course, the invention is not limited to the embodiment described and variants may be provided without departing from the scope of the invention as defined by the claims.
En particulier, l'installation peut avoir une géométrie différente de celle décrite.In particular, the installation may have a geometry different from that described.
Le module peut comporter un nombre différent de plateaux.The module may have a different number of trays.
