ABSTRACT:
The invention provides a honeycomb formed structure drying method including causing undried honeycomb formed structures10placed on stands12to pass through a drying apparatus1, thereby drying the undried honeycomb formed structures through high-frequency heating, to thereby form dried honeycomb formed structures11; removing the dried honeycomb formed structures11from the stands12; cooling the stands12which have been heated dried in the drying apparatus1are cooled to a temperature lower than the gelation temperature of the undried honeycomb formed structures10; placing newly formed undried honeycomb formed structures10on the cooled stands12; drying the undried honeycomb formed structures by passing through the drying apparatus1; and repeating these operations. The honeycomb formed structure drying method prevents deformation such as warpage of partition walls of honeycomb formed structures during drying thereof.
