Method and apparatus for drying honeycomb formed body

An undried honeycomb formed body 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 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 is increased, thereby reducing a difference between amount of water vaporized from the inner part of the undried honeycomb formed body 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 and that of the outer part thereof, thereby producing a dried honeycomb formed body 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.
