RF Dryer
•In a radio frequency heating system the RF generator creates an alternating
electric field between two electrodes, which produces heat.
•The amount of heat generated in the product is determined by the frequency, the
square of the applied voltage, dimensions of the product and the dielectric loss
factor of the material, which is essentially a measure of the ease with which the
material can be heated by radio frequency waves.
