Title:
DEHYDRATING/DRYING APPARATUS AND METHOD OF DEHYDRATION/DRYING
Document Type and Number:
WIPO Patent Application WO/2008/038610
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a dehydrating/drying apparatus with which a work to be cleaned which has been washed with water can be dehydrated and dried to separate and remove the water therefrom; and a method of dehydration/drying. [MEANS FOR SOLVING PROBLEMS] A work to be cleaned (A) which has been washed with water is immersed in a cleaning liquid (B) which is placed in an immersion tank (4) and is obtained by mixing a fluorochemical solvent with an alcohol solvent. The water adherent to the work (A) is thus dissolved in the alcohol solvent contained in the cleaning liquid (B) to thereby separate/remove the water therefrom. The work (A) after the immersion cleaning is taken out of the immersion tank (4), moved to a vapor layer (5) comprising the vapor (Ba) of the cleaning liquid (B), and heated to a temperature at which vaporization of the cleaning liquid (B) is accelerated. The work (A) after the vapor cleaning is taken out of the vapor layer (5) and heated with far infrared rays radiated by far infrared heaters (6, 6) to evaporate the alcohol solvent adherent to the work (A). Thus, the work is dehydrated and dried.
