PURPOSE: To provide a technology capable of saving operation energy in an adsorption apparatus.

CONSTITUTION: This adsorption apparatus consists of divided adsorbents 1a and 1b, a heating source 2 placed on the upstream of the adsorbent 1a, a blower 3 feeding air to the adsorbent and a wind passage 4. In the regenerating process in accordance with the constitution, the adsorbent 1a at more downstream than the heating source 2 is heated by working the heat source 2 and making the air fed from the blower 3 a high temp. wind. Moisture is released by heating the adsorbent 1a with the high temp. wind and radiation heat. After the regeneration of the adsorbent 1a is finished, the adsorbent 1b is regenerated by the warm wind due to the remaining heat of the adsorbent 1a.
