Abstract
The invention provides a honeycomb formed structure drying method including causing undried honeycomb formed structuresplaced on standsto pass through a drying apparatus, thereby drying the undried honeycomb formed structures through high-frequency heating, to thereby form dried honeycomb formed structures; removing the dried honeycomb formed structuresfrom the stands; cooling the standswhich have been heated dried in the drying apparatusare cooled to a temperature lower than the gelation temperature of the undried honeycomb formed structures; placing newly formed undried honeycomb formed structureson the cooled stands; drying the undried honeycomb formed structures by passing through the drying apparatus; 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.
