PURPOSE: To obtain a compact and inexpensive storage device of perishable materials by constituting plural adsorbing materials divided by an inner partition plate to adsorb and remove excessive CO2 and flow channel change parts made of dampers at the upstream and downstream sides of the adsorbing materials in an integrated way.

CONSTITUTION: The above-mentioned storage device of perishable materials has adsorbing materials 135 of two sections divided by an inner partition plate 139 to adsorb and remove excessive CO2. The storage device is equipped with a device 102 of adsorbing carbon dioxide gas provided with flow channel change parts 136 and 137 composed of dampers 152-159 at the upstream and downstream sides of the adsorbing materials 135 and 136 of two sections in an integrated way. According to the above-mentioned constitution, since distance in which a circulating gas is passed can be shortened, reduction in an amount of circulating air by pressure loss is small and a required amount of circulating air can be secured by a small-size blower. Since connecting pipings can be lessened and a container to put the adsorbing materials 135 and 136 can be simplified, the device is compacted to provide an inexpensive storage chamber of perishable materials. In the figure, the storage chamber 1 and a carbon dioxide gas generator 101 are shown.
