Abstract
Method and apparatus for quickly drying shaped ceramic bodies (3) having a complex surface (3a, 4a) with enriched unevenness, and a simple surface (3b, 4b) which is less uneven as compared to the complex surface (3a, 4a), without causing drying cracks and within a shortened time. The shaped ceramic body (3) within a drying chamber (1) is primarily heated from the simple surface (3b, 4b) by a main infrared heater (6), which is arranged on the simple surface side. Preferably, the ceramic body (3) is also heated by an auxiliary infrared heater (7) of a relatively low temperature, which is arranged on the side of the complex surface (3a, 4a), or dried while admitting a hot air into the drying chamber (1) with a low speed.
