Abstract
Novel method and apparatus are disclosed for dielectrically drying green ceramic or wet honeycomb structures, by rotating such structures about their longitudinal axis between a pair of parallel dielectric electrodes and simultaneously blowing heated air through the longitudinal cells of the honeycomb structure. Preferably the dielectric electrodes are oriented parallel with the longitudinal axis of the honeycomb structure, and the rotation thereof between the electrodes accordingly results in a more uniform energy transfer to the honeycomb structure by leveling out the non-uniformities and variations in the dielectric field.
