Abstract
A bell jar includes a metallic bell jar (), and a metallic base plate () on which the bell jar () is placed, and packing () seals an inside of a container. To the base plate (), a pressure gauge (), a gas introduction line (), and a gas discharge line () are connected so as to allow monitoring of internal pressure of the bell jar () and introduction and discharge of a gas. A vacuum pump () is provided in a path of the gas discharge line (), and the vacuum pump () reduces internal pressure of the bell jar so as to be lower than vapor pressure of water. The vacuum pump () reduces the internal pressure of the bell jar so as to be lower than vapor pressure of water, thereby efficiently removing moisture, and completing drying of the bell jar in a short time.
