Abstract

The tunnel (1) has microwave generators (2) arranged on successive frames (4) and performing drying and dehydration of different organic or mineral materials (5), where the tunnel is made of metallic or non-metallic material. The organic or mineral materials are linearly routed inside the tunnel by using a conveyor belt (3) to transfer the materials in a continuous manner. The routed materials are subjected to an influence or successive action of electromagnetic fields of the generators during transfer of the materials based on the position of the generators.

Description

La présente invention concerne un procédé de séchage, de déshydratation deThe present invention relates to a method for drying, dehydrating

différentes matières (5) d'origines organiques ou minérales par un tunnel (1) équipé de générateurs de micro-ondes (2). Ces matières sont acheminées à l'intérieur de ce tunnel (1) métallique ou autre matériau au moyen d'un tapis roulant (3) ou de tout autre moyen de circulation, de transfert, d'acheminement linéaire non sensible aux champs électromagnétiques et en mouvement continue à l'intérieur du tunnel d'ont la vitesse de défilement est variable. Ce tunnel (1) peut être de longueurs et de largeurs variables, il est équipé de 10 cadres (4) successifs de structure sur les quels sont disposés les générateurs de micro-ondes (2) de puissances et de fréquences variables. La position du générateur de micro-ondes (2) sur ces cadres (4) successifs peut être rectiligne ou être déphasées sur le périmètre du cadre (4) les uns par rapport aux autres, par cadre (4) de zéro à trois cent soixante degrés.  different materials (5) of organic or mineral origins by a tunnel (1) equipped with microwave generators (2). These materials are conveyed inside this tunnel (1) metal or other material by means of a treadmill (3) or any other means of circulation, transfer, linear routing not sensitive to electromagnetic fields and continuous movement inside the tunnel have the scrolling speed is variable. This tunnel (1) can be of variable lengths and widths, it is equipped with 10 successive frames (4) of structure on which are arranged the microwave generators (2) of variable powers and frequencies. The position of the microwave generator (2) on these frames (4) can be successive rectilinear or out of phase on the perimeter of the frame (4) relative to each other, by frame (4) from zero to three hundred and sixty degrees.

15 La matière (5) ainsi acheminée dans le tunnel (1) subit pendant la durée du transfert l'influence et l'action successive des champs électromagnétiques des générateurs de micro-ondes (2) selon leurs positionnement dans l'espace durant son déplacement sur le tapis roulant (3) ou de tout autre moyen de circulation, de transfert, d'acheminement linéaire non sensible aux champs électromagnétiques.The material (5) thus conveyed in the tunnel (1) undergoes during the duration of the transfer the influence and the successive action of the electromagnetic fields of the microwave generators (2) according to their positioning in the space during its displacement. on the treadmill (3) or any other means of circulation, transfer, linear routing not sensitive to electromagnetic fields.

20 Cela à pour effet de produire sous l'action des champs électromagnétiques générés sur l'humidité contenue dans la matière une chaleur par induction suffisante à la faire évaporer, a évaporer également les molécules d'eau et autres molécules évaporables contenues, liquides et esprits divers sur l'ensemble de la matière en déplacement. Les micro-ondes n'ont pratiquement plus d'action de déshydratation à partir du 25 moment ou la matière ne comporte plus de molécules d'eau et autres molécules évaporables sensibles aux champs des micro-ondes, elle se trouve donc être partiellement ou totalement déshydratée selon la durée du transit dans le tunnel. Un dispositif d'aspiration (6) permanent disposée à l'extrémité entrante (7) du Tunnel (1) évacue l'air chargé et humide du tunnel ,l'air est renouvelé de manière 30 continue par une ouverture appropriées située à l'extrémité sortante (8) du tunnel(1). L'extrémité entrante (7) du tunnel est pourvue d'un dispositif de fermeture (9), d'obturation automatique par conformateur et de confirmation aux formes introduites pour interdire totalement ou partiellement le passage de l'air. Cet air humide extrait et chargé d'autres éléments volatils issus et dégagés par la 35 matière en circulation dans le tunnel (1) peut être traité par refroidissement et condensation dans des conduites spéciales de condensation avec une récupération du condensât. Ce liquide ou condensât récupéré peut être par la suite distillé selon divers procédés et techniques opportuns et adaptés pour en extraire les divers types de 40 molécules qui y sont contenues. Ce tunnel (1) de séchage par micro-ondes peut fonctionner de manière continue à partir du moment ou il est approvisionné de manière continue. Le volume de matière traitée en continue est proportionnel à la longueur du tunnel (1), est également relatif à sa nature, à sa masse, à la quantité d'humidité et 45 autres molécules évaporables contenues.This has the effect of producing, under the action of the electromagnetic fields generated on the moisture contained in the material, an induction heat sufficient to evaporate it, also to evaporate the water molecules and other evaporable molecules contained, liquids and spirits. various on the whole of the moving matter. Microwaves have practically no dehydration action from the moment when the material no longer contains water molecules and other evaporable molecules sensitive to the microwave fields, it therefore becomes partially or totally dehydrated according to the transit time in the tunnel. A permanent suction device (6) disposed at the incoming end (7) of the Tunnel (1) discharges the charged and humid air from the tunnel, the air is continuously renewed by an appropriate opening located at the outgoing end (8) of the tunnel (1). The incoming end (7) of the tunnel is provided with a closure device (9), automatic closure by shaper and confirmation forms introduced to totally or partially prohibit the passage of air. This moist air extracted and charged with other volatile elements from and released by the circulating material in the tunnel (1) can be treated by cooling and condensation in special condensing pipes with condensate recovery. This recovered liquid or condensate may subsequently be distilled according to various suitable methods and techniques adapted to extract the various types of molecules contained therein. This microwave drying tunnel (1) can operate continuously from the moment it is supplied continuously. The volume of material treated continuously is proportional to the length of the tunnel (1), is also related to its nature, its mass, the amount of moisture and 45 other evaporable molecules contained.
