La présente invention se rapporte à un nouveau type de séchoir destiné à déshydrater des matières à perte de masse lente ou rapide, de faible ou forte densité, entières ou coupées, telles que fruits, légumes, céréales, etc.. en permettant une déshydratation totale ou partielle des produits, à volonté.VERSATILE DRYER FOR DEHYDRATION
sr 7
TOTAL OR PARTIAL OF PARTICULARLY FOOD PRODUCTS
The present invention relates to a new type of dryer intended to dehydrate materials with a slow or rapid loss of mass, of low or high density, whole or cut, such as fruits, vegetables, cereals, etc. by allowing total dehydration or partial products, at will.
Le but de l'invention est de réaliser un appareil de conception simple, assurant à la fois le séchage et/ou la stérilisation et d'un maniement simple permettant l'obtention du produit désiré. The object of the invention is to provide a device of simple design, ensuring both drying and / or sterilization and simple handling allowing the production of the desired product.
A cet effet, l'invention a pour objet un séchoir pour la déshydratation totale ou partielle de produits notamment alimentaires, caractérisé en ce qu'il comprend un tunnel de séchage allongé dans lequel sont superposés horizontalement et alternés un certain nombre de tapis de convoyage des produits depuis l'entrée, à une extrémité du tunnel, sur le tapis supérieur jusqu'd l'extrémité d'évacuation du tapis inférieur, au moins deux circuits semi-indépendants de circulation d'air de séchage en boucles horizontales fermées superposées, chaque boucle comportant une trajectoire extérieure audit tunnel et une trajectoire intérieure affectant un nombre déterminé de tapis, et étant munie de moyens de génération de chaleur, de moyens d'introduction d'air neuf, de moyens de circulation de l'air de séchage et de moyens d'évacuation de 1'air humide et en ce que lesdits circuits comportent des moyens propres à régler un éventuel transfert d'air dsun circuit au circuit voisin, extérieurement au tunnel de séchage. To this end, the subject of the invention is a dryer for the total or partial dehydration of products, in particular foodstuffs, characterized in that it comprises an elongated drying tunnel in which a number of conveyor belts are superimposed horizontally and alternate produced from the entrance, at one end of the tunnel, on the upper belt to the discharge end of the lower belt, at least two semi-independent circuits of drying air circulation in closed horizontal superposed loops, each loop comprising an external path to said tunnel and an internal path affecting a determined number of mats, and being provided with means for generating heat, means for introducing fresh air, means for circulating the drying air and means for evacuating moist air and in that said circuits include means suitable for regulating a possible transfer of air from a circuit to the neighboring circuit, outside the tunnel l drying.
Du fait de sa structure de séchage étagée, chaque circuit de circulation d'air ayant ses propres caractéristiques et ses propres réglages en températures, hygrométrie et vitesse de circulation d'air, le dispositif selon l'invention procure une très grande facilité et souplesse d'emploi permettant une parfaite adéquation des conditions de séchage au type de produit traité et à la qualité du séchage ou de la stérilisation désirée.

utilisables conjointement dans le tunnel de séchage
Le séchoir représenté sur les dessins comporte un tunnel de séchage allongé l dans lequel sont superposés horisontalement plusieurs tapis de convoyage T1 à T6 en alternance.Other characteristics and advantages will emerge from the description which follows of an embodiment of the device according to the invention, description given to tltre of example 4 only and with reference to the appended drawings in which
- Fig. 1 shows a schematic perspective view of a
dryer in accordance with the invention
- Fig. 2 shows an end view of the dryer of Fig.l;
- Fig. 3 represents a top view of the dryer,
- Fig. 4 represents a side view of the drying tunnel,
and,
- Fig. 5 illustrates in partial views three types of carpet
can be used together in the drying tunnel
The dryer shown in the drawings comprises an elongated drying tunnel l in which several conveyor belts T1 to T6 are stacked horizontally alternately.
c'est-a-dire chacun alimentant le tapis immédiatement en dessous (Fig. 4). that is to say each feeding the belt immediately below (Fig. 4).
L'introduction des produits à traiter se fait à la partie supérieure du .tunnel, à une extrémité, sur l'extrémité dépassante du premier tapis ou tapis supérieur T1. The products to be treated are introduced at the upper part of the tunnel, at one end, onto the protruding end of the first carpet or upper carpet T1.
L'extraction des produits se fait à l'extrémité dépassante du dernier tapis ou tapis inférieur T6. The products are extracted at the protruding end of the last carpet or lower carpet T6.
Eventuellement un recyclage des produits évacués par le dernier tapis T6 est possible par réintroduction sur l'avant-dernier tapis T5 suivant la flèche R (Fig. 4) par l'intermédiaire d'un registre articulé 3. Possibly recycling of the products evacuated by the last belt T6 is possible by reintroduction on the penultimate belt T5 according to the arrow R (Fig. 4) via an articulated register 3.
Sur un des côtés du tunnel 1 sont disposées deux gaines horizontales superposées 4 et 5 séparées par une cloison horizontale 6 et communiquant toutes les deux avec les deux extrémités du tunnel, chacune avec la demi-partie supérieure ou inférieure du tunnel 1. A cet effet la paroi latérale la du tunnel, côté gaines 4,5, est interrompue aux ex trémités pour permettre la circulation d'air entre chaque gaine 4,5 et la moitié concernée du tunnel 1 qui est ainsi fictivement divisé en deux zones semi-independantes supérieure A et inférieure B (Fig. 2). On one side of the tunnel 1 are arranged two superimposed horizontal sheaths 4 and 5 separated by a horizontal partition 6 and both communicating with the two ends of the tunnel, each with the upper or lower half-part of the tunnel 1. For this purpose the side wall of the tunnel, on the duct side 4.5, is interrupted at the ends to allow air circulation between each duct 4.5 and the half concerned of the tunnel 1 which is thus fictitiously divided into two semi-independent upper zones A and lower B (Fig. 2).
Dans chaque gaine extérieure 4,5 sont disposés un générateur de chaleur symbolisé en 7 et 8 respectivement, un ventilateur symbolisé en 9 et 10 respectivement, et un registre d'entrée d'air neuf 11 et 12 respectivement. In each outer sheath 4.5 are arranged a heat generator symbolized in 7 and 8 respectively, a fan symbolized in 9 and 10 respectively, and a fresh air inlet register 11 and 12 respectively.
En outre, du côté introduction des produits la gaine 4 comporte un conduit 13 d'évacuation d'air humide à l'atmosphère, muni d'un volet mobile 14 de réglage de la section de passage. De même la gaine 5 comporte au droit de I'extrémité d'introduction des produits un registre mobile 15 de réglage de l'évacuation a l'atmosphère de l'air humide. Ce registre 15 se trouve, de même que le conduit 13, sensiblement au droit du passage faisant communiquer le tunnel 1 avec les gaines 4 et 5. In addition, on the product introduction side, the sheath 4 comprises a duct 13 for evacuating moist air to the atmosphere, provided with a movable flap 14 for adjusting the passage section. Likewise, the sheath 5 comprises, at the level of the end of the introduction of the products, a mobile register 15 for adjusting the evacuation to the atmosphere of humid air. This register 15 is, like the conduit 13, substantially at the right of the passage making the tunnel 1 communicate with the sheaths 4 and 5.
Enfin la cloison séparatrice 6 entre les gaines 4 et 5 comporte, toujours au droit de la communication entre tunnel 1 et gaine 4,5, un orifice de passage obturable plus ou moins à l'aide d'un registre~l6 mobile vers le bas autour d'un axe horizontal (Fig. 1). Finally the separating partition 6 between the sheaths 4 and 5 comprises, still in line with the communication between tunnel 1 and sheath 4.5, a passage orifice closable more or less using a register ~ l6 movable downwards around a horizontal axis (Fig. 1).
Dans chaque gaine 4,5 est placée une sonde hygrométrique 17 sensiblement entre les générateurs d'air chaud 7, 8 et l'orifice de communication entre l'enceinte du tunnel 1 et les gaines 4 et 5, côté introduction des produits. In each sheath 4.5 is placed a hygrometric probe 17 substantially between the hot air generators 7, 8 and the communication orifice between the enclosure of the tunnel 1 and the sheaths 4 and 5, on the product introduction side.
Des déflecteurs cintrés fixes -18 (Fig. 3) sont avantageusement disposés dans les angles- libres du parallélépi pède délimité par le tunnel 1 et les gaines 4,5 afin de faciliter la circulation en boucle fermée des flux d'air. Fixed curved deflectors -18 (Fig. 3) are advantageously arranged in the free angles of the parallelepeped path delimited by the tunnel 1 and the ducts 4,5 in order to facilitate the circulation in a closed loop of the air flows.
La Fig. 5 représente trois types de tapis de convoyage utilisables conjointement dans l'enceinte-l. C'est ainsi queles tapis supérieurs T1 et T2 pourront être constitués par le tapis 19 à grandes perforations 20, les tapis intermédiaires
T3 et T4 pourront être constitués par le tapis 21 à perforations moyennes 22 et les deux tapis inférieurs T5 et T6 par le tapis 23 à petites perforations 24. L'emploi de ces divers types de tapis permet de limiter les problèmes d'interface et d'améliorer l'homogénéité du séchage et sa rapidité.Fig. 5 shows three types of conveyor belts usable jointly in the enclosure-1. This is how the upper carpets T1 and T2 can be formed by the carpet 19 with large perforations 20, the intermediate carpets
T3 and T4 could be constituted by the mat 21 with medium perforations 22 and the two lower belts T5 and T6 by the mat 23 with small perforations 24. The use of these various types of mat makes it possible to limit the problems of interface and d '' improve the uniformity of drying and its speed.
Le fonctionnement du dispositif représenté et décrit ci-dessus est le suivant. The operation of the device shown and described above is as follows.
Les deux gaines 4 et 5 déterminent deux flux de circulation d'air de séchaqe en boucle fermée horizontale. The two ducts 4 and 5 determine two flows of drying air circulation in a horizontal closed loop.
Le flux supérieur emprunte la gaine 4 et la demipartie supérieure A du tunnel 1. The upper flow follows the sheath 4 and the upper half-part A of the tunnel 1.
Le flux inférieur emprunte parallèlement la gaine 5 et la demi-partie inférieure B. The lower flow runs parallel to the sheath 5 and the lower half-part B.
La jonction entre gaines et tunnel se fait aux extrémités de l'ensemble par les passages ménagés par les interruptions de la cloison la. The junction between ducts and tunnel is made at the ends of the assembly by the passages provided by the interruptions of the partition la.
Ces deux circuits sont semi-indépendants en ce sens qu'il n'y a pas de cloisonnement étanche entre circuitsà-l'in- térieur du tunnel 1. These two circuits are semi-independent in the sense that there is no watertight partitioning between circuits inside the tunnel 1.
Les deux flux d'air de séchage peuvent être commandés indépendamment l'un de l'autre grâce aùx dispositifs indépendants 7 à 10 et 17. Ceci permet de moduler à volonté le débit, la température et le degré d'humidité de chacun des flux. The two drying air flows can be controlled independently of each other thanks to independent devices 7 to 10 and 17. This makes it possible to modulate at will the flow rate, the temperature and the degree of humidity of each of the flows. .
Le séchoir selon l'invention est polyvalent car il permet une déshydratation totale ou partielle ainsi qu'une stérilisation des produits. The dryer according to the invention is versatile because it allows total or partial dehydration as well as sterilization of the products.
La déshydratation totale est obtenue en utilisant la totalité de l'appareil,c'est-à-dire en mettant en service les générateurs 7 et 8 et les ventilateurs 9 et 10. Total dehydration is obtained by using the entire apparatus, that is to say by commissioning the generators 7 and 8 and the fans 9 and 10.
Les registres 11 et 12 d'introduction d'air neuf sont commandés à la main ou mécaniquement. The registers 11 and 12 for introducing fresh air are controlled by hand or mechanically.
La sonde 17 de contrôle -hygrométrique de la gaine supérieure 4 règle le volet 14 et commande le rejet à l'extérieur de l'air humide de la gaine 4. The hygrometric control probe 17 of the upper sheath 4 regulates the flap 14 and controls the rejection outside of the humid air of the sheath 4.
La sonde 17 de la gaine inférieure 5 règle la position du registre 15 et commande le rejet à l'extérieur de l'air humide de la gaine 5. The probe 17 of the lower sheath 5 regulates the position of the damper 15 and controls the rejection outside of the humid air of the sheath 5.
A tout moment, il est possible de transférer une partie du flux d'air inférieur vers l'étage supérieur, ou inversement éventuellement, grâce au registre 16 pouvant être
commandé manuellement ou mécaniauement à partir de n'importe quel paramètre,par exemple le degré hygrométrique.At any time, it is possible to transfer part of the lower air flow to the upper floor, or vice versa possibly, thanks to the register 16 which can be
controlled manually or mechanically from any parameter, for example the humidity.
Le séchoir permet une déshydratation partielle(pré- ou post-séchage) ou une stérilisation, par ltutilisation de la gaine inférieure 5 et plus précisément en utilisant les tapis T5 et T6 en introduisant les produits à traiter (en particulier des produits conditionnes à stériliser)par le regis tre 3. The dryer allows partial dehydration (pre- or post-drying) or sterilization, by the use of the lower sheath 5 and more precisely by using the belts T5 and T6 by introducing the products to be treated (in particular packaged products to be sterilized) by register 3.
Les ventilateurs indépendants 9 et 10 sont régulables en permanence et assurent une ventilation horizontale sans pression par léchage du produit dense ou non. The independent fans 9 and 10 are continuously adjustable and provide horizontal ventilation without pressure by licking the dense product or not.
Les générateurs 7 et 8 sont mono ou bi-énergie,contrôlésthermiquement indépendamment de façon à obtenir un gradient thermique d'étage à la demande et peuvent recevoir un récupérateur d'énergie. Generators 7 and 8 are mono or bi-energy, thermally controlled independently so as to obtain a stage thermal gradient on demand and can receive an energy recovery unit.
Les sondes 17 peuvent être remplacées par des thermocouples sur bulbe humide ou tout autre dispositif équivalent. The probes 17 can be replaced by thermocouples on a wet bulb or any other equivalent device.
Le séchoir selon l'invention présente un excellent rendement instantané à la demande grâce à la température et à l'hygrométrie programmables. The dryer according to the invention has an excellent instantaneous output on demand thanks to the programmable temperature and humidity.
I1 permet également le recyclage des produits insuffisamment secs. It also allows the recycling of insufficiently dry products.
Le nombre de circuits indépendants d'air de séchage en boucle fermée horizontale n'est pas limité à deux,il suffit de-multiplier les gaines latérales superposées telles que 4 et 5 avec chacune son propre système de chauffage, circulation d'air et contrôle d'entrée d'air neuf et de sortie d'air humide. Dans un tel séchoir multi-étage chaque gaine peut communiquer avec sa ou ses gaines adjacentes par un dis positif du type du registre 16. The number of independent horizontal closed-loop drying air circuits is not limited to two, it suffices to multiply the superimposed lateral ducts such as 4 and 5, each with its own heating, air circulation and control system. fresh air inlet and humid air outlet. In such a multi-stage dryer, each sheath can communicate with its adjacent sheath (s) by means of a device of the type of the register 16.
Enfin, l'invention n'est pas limitée au mode de réalisation représente et décrit ci-dessus mais en couvre toutes les variantes notamment en ce qui concerne la nature, structure ou agencement des moyens de chauffage, de circulation d'air, de régulation d'entrée et de sortie des divers flux et de contrôle de température et d'hygrométrie. Finally, the invention is not limited to the embodiment shown and described above, but covers all variants thereof, in particular as regards the nature, structure or arrangement of the heating, air circulation, and regulation means. of input and output of the various flows and of control of temperature and hygrometry.
