Title:
METHOD AND APPARATUS FOR DRYING SUBSTANCE TO BE DRIED
Document Type and Number:
WIPO Patent Application WO/2007/136005
Kind Code:
A1
Abstract:
A high-boiling solvent contained in a substance to be dried can be efficiently
removed and the attainment of drying apparatus installation space saving and
energy saving can be realized. A method is provided in which a substance to be
dried which contains a first solvent is dried while conveying it in a chamber (38).
The method comprises: a first drying step which is a step preceding the chamber
(38) and in which the substance to be dried is dried to a drying point; and a second
drying step in which an atmosphere of a vapor of a second solvent having a lower
boiling point than the first solvent is formed inside the chamber (38) and the
substance to be dried is dried so that the temperature of the substance as measured
at the inlet of the chamber (38) is lower by a given value than the temperature of
the vapor atmosphere.
