The device comprises many small chambers, separated from each other and grouped in categories A, B, C and D which are all provided with the adsorbant. The categories B, C and D are all traversed by a partial current of drying gas medium so as to dehumidify the latter. On the contrary, the category (A) is traversed by another gas current which is intended to regenerate the adsorbant contained in the small chambers of this category. The gas currents of the drying medium have a variable humidity degree and are activated in the different steps of a drying process The device, in operation, distributes permanently the gas current and assigns them to the different small chambers so that each small chamber is periodically traversed by all the gas currents of the drying medium starting by the less humid currents and ending by the most humid currents; thereafter, each small chamber is finally traversed by the adsorbant regeneration gas medium. After each distribution of gas currents, there must be at least one small chamber of each category that is assigned to the following group of the cycle. |
