Method and apparatus for drying honeycomb formed body

An undried honeycomb formed body 41 is subjected to high-frequency heating in an atmosphere where humidity and temperature are maintained at 30 to 65% and 75 to 130° C., respectively, such that 50 to 99 mass % of water contained in the undried honeycomb formed body 41 is evaporated at the end of hig...

Beschreibung
Zusammenfassung:	An undried honeycomb formed body 41 is subjected to high-frequency heating in an atmosphere where humidity and temperature are maintained at 30 to 65% and 75 to 130° C., respectively, such that 50 to 99 mass % of water contained in the undried honeycomb formed body 41 is evaporated at the end of high-frequency heating, whereby the amount of water vaporized from the outer part of the undried honeycomb formed body 41 is increased, thereby reducing a difference between amount of water vaporized from the inner part of the undried honeycomb formed body 41 and that of water vaporized from the outer part thereof as well as reducing a difference between drying degree of the inner part of the undried honeycomb formed body 41 and that of the outer part thereof, thereby producing a dried honeycomb formed body 42 in which deformation of the partition walls is suppressed. The invention provides a honeycomb formed body drying method which prevents deformation of partition walls of the honeycomb formed body during drying thereof.
