METHOD FOR DRYING OBJECT TO BE DRIED AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2011/024402
Kind Code:
A1
Abstract:
Disclosed is a method for drying an object to be dried, wherein an object to be dried can be safely removed from a device by boiling and evaporating a high-boiling-point solvent used to dry the object to be dried, to remove the high-boiling-point solvent from the surface of the object to be dried, so that the burden on the environment and the running cost can be reduced.
Within a solvent introduction tank (1) to which a high-boiling-point solvent (2), the boiling point of which is higher than that of water, is introduced, an object to be dried (25) is brought into contact with the high-boiling-point solvent (2) which has been heated to the boiling point of water or more, to boil and evaporate moisture attached to the object to be dried (25). After that, the object to be dried (25) is transferred to a vacuum drying tank (10) within a hermetically sealed space, and the inside of the vacuum drying tank (10) is decompressed and heated to the boiling point of the high-boiling-point solvent (2) or more while the communication between the solvent introduction tank (1) and the vacuum drying tank (10) is blocked, so that the high-boiling-point solvent (2) attached to the surface of the object to be dried (25) is evaporated to dry the object to be dried (25).
