Because of the unique heating character of RF heating compared with conventional heating methods, such as rapid and volumetric heating, RF heating has been successfully applied in, several industry sectors, such as the textile and wood industry. In the food processing area, RF heating has already been successfully applied for drying of food materials, post-baking of biscuits & crackers and other food products, and thawing/tempering of frozen meat. Recently, new applications of RF heating are emerging, such as pasteurization/sterilization of foods and disinfestations of agricultural products.
