DEWATERING METHOD

WIPO Patent Application WO/2010/090270

A1

Disclosed is a dewatering method with which none of the spotting that occurs with movement of articles between dip tanks is produced, dewatering capability is not reduced even with complex-shaped articles, suspension of water in the dewatering solvent in the dip tank can be suppressed, and stable dewatering capability can be maintained continuously over a long period in one dip tank. With the article dewatering method, a fluorine-based solvent that contains an alcohol is used as the dewatering solvent and the dewatering solvent in the dip tank is boiled. Dewatering solvent vapor is condensed in the upper part of the dip tank, the condensed dewatering solvent is returned to the dip tank after water is removed outside of the dip tank. Articles to which water is adhered are dipped in the boiling dewatering solvent inside the dip tank, the water is removed, and the articles are taken out.
