Abstract
The drying method performs drying the honeycomb formed article by such an arrangement that superheated steam or mixed gas of steam and hot air, temperature and humidity of which is regulated so that wet-bulb temperature thereof becomes 70° C. or higher, is made to pass through the cells of the honeycomb formed article. The drying apparatus includes a steam supply unit that supplies the superheated steam, a buffer chamber that aligns the superheated steam supplied from the steam supply unit, an upper chamber disposed above the buffer chamber to locate the honeycomb formed article, and a hood unit that recovers the superheated steam which has passed through the honeycomb formed article.
