<p>PURPOSE:To make it possible to change a storage container from highly damp condition to low and stable damp condition within a short time by forming a ventilating route in a vaporproof storage container and installing a dry unit to absorb the damp and a fan to cause hot air convection in the ventilating route. CONSTITUTION:A ventilating route 6 is formed in a moistureproof storage container 3 by installing a ventilating route forming means 4 (e.g. a plate) in the moistureproof storage container 3. A dry unit 7 in which a zeolite-based moisture absorbent and a semiconductor heater to heat and regenerate the absorbent are set is installed in the ventilating route 6. Furthermore, a fan to cause hot air convection 8 is installed in the ventilating route 6. As a result, the humidity condition inside the storage container is changed from a high one to a low and stable one in a short period and to storage surroundings can be kept optimum for stored objects all the time.</p> |
