Heat and mass transfer in a radiofrequency dryer

Over the last few years, radio frequency, also known as dielectric heating has become well established in a number of process industr1es because of its unique heat transfer characteristics which make it a fourth category, volumetric heating, alongside the well established mechanisms of radiation, conduction and convection. RF has become widely accepted in the textile, food, woodworking and paper converting industries amongst others, even though a fully integrated theory, which brings together heat and mass transfer, electrical theory, material characteristics, and process parameters has yet to be established.
