Zusammenfassung:	The present invention relates to a device for treating air at low temperatures and controlled relative humidity for the dehydration of thermosensitive products, with the aim of obtaining dry products with extremely low nutritional and aromatic degradation, such as herbs and spices. Said device comprises: a Peltier module that comprises a high-temperature heat sink (1), having at least one central portion (A) and two end portions (B); and at least two fans (5), one located laterally on the left of the high-temperature heat sink and the other located laterally on the right of the low-temperature cooler. As a result, by configuring the thermoelectric device to carry out the processes of cooling/dehumidification simultaneously, followed by gentle heating, suitable treated air is obtained at a low speed for dehydration of the thermosensitive product, for use in a small drying setting on a domestic scale. La présente invention concerne un dispositif de traitement de l'air à basses températures et d'humidité relative régulée pour la déshydratation de produits thermosensibles, visant à obtenir des produits secs avec une très faible dégradation nutritionnelle et aromatique, tels que des herbes et des épices. Ledit dispositif comprend un module Peltier comportant un dissipateur de température élevée (1), dans lequel se trouvent au moins une partie centrale (A) et deux parties aux extrémités (B) ; au moins deux ventilateurs (5), l'un étant situé latéralement à gauche du dissipateur de température élevée et l'autre étant situé latéralement à droite du réfrigérateur à basse température. Ainsi, en structurant le dispositif thermoélectrique pour la réalisation des processus de refroidissement/déshumidification simultanés et, ensuite, le chauffage doux, on obtient de l'air traité et approprié à faible vitesse pour la déshydratation du produit thermosensible, l'air étant destiné à être utilisé dans un petit environnement de séchage à usage domestique. A presente invenção se refere a um dispositivo de tratamento de ar a baixas temperaturas e umidade relativa controlada para a desidratação de produtos termossensíveis, visando a obtenção de produtos secos com baixíssima degradação nutricional e aromática, tais como ervas e especiarias. O referido dispositivo compreende: um módulo Peltier que compreende um dissipador de alta temperatura (1), em que possui pelo menos uma porção central (A) e duas porções nas extremidades (B); pelo menos dois ventiladores (5), um localizado late
