Radio frequency pasteurization

December 5, 2012
radio frequency pasteurization macrowaveRadio Frequency Company’s Macrowave pasteurization system uses a high-frequency (40 MHz) electric field to control pathogens in products such as nut meats, flour, pasta and fishmeal. Two systems are available: one with a conveyor belt to handle a continuous flow of dry products and a batch-configured unit to handle bulk containers. The system evenly heats the product to a kill temperature, and is effective against both microbes and insects. Radio frequency heating is direct, without waste, as only the product is heated.
