WIPO Patent Application WO/2005/023503
Kind Code:
A1
Abstract:
A method for drying a honeycomb formed article, which comprises subjecting an undried honeycomb formed article (41) to high-frequency heating in an atmosphere of a temperature of 75 to 130°C and a humidity of 30 to 65 %, so as for 50 to 99 mass % of the water in the undried honeycomb formed article (41) to evaporate finally from the article, wherein the amount of water evaporated from the outer part of the undried honeycomb formed article (41) is increased, to reduce the difference in the amounts of water evaporated from the outer part and the inner part of the undried honeycomb formed article (41) and reduce the difference in the degrees of drying in the outer part and the inner part of the undried honeycomb formed article (41), thereby preparing a dried honeycomb formed article (42) suppressed in the deformation of partitions. The method can be used for drying a honeycomb formed article while suppressing the deformation of partitions of the honeycomb formed article.
