ABSTRACT
Radio frequency (RF) dielectric heating is widely used in many industries including the food industry. Some of these applications have been around for a long time, some are just being developed, and some are still at the research and development (R&D) stage. The most rapidly increasing application of RF heating in the industry is drying (Jones, 1987). The drying applications include textile products, paper, glass ber and spools, water-based glues, wood and sawdust, tobacco leaves and biscuits, leathers and hide, powder products, water inks, and pharmaceutical products (Biryukov, 1968; Barker, 1983; Jones, 1987, 1996; Roussy and Pearce, 1995).
