The adsorption chamber (11) is rotatable with respect to the feeding and discharging lines (106, 107, 108, 109) so that the adsorption conduits may be fluidically connected in temporal alternation, wherein the gas is dried in a drying sector (102), and the adsorption material (123) is regenerated in the regeneration sector (103). The first feeding line (106) is configured such that the gas stream to be dried may be fed to the regeneration sector (103) as a full flow.
