Radio Frequency Company Macrowave pasteurization systems are designed for conveyorized applications of bagged or in bulk, dog biscuits, kibbles and other dry pet food products. In a Macrowave heating system, an RF generator creates an alternating electric field between two electrodes. The material to be treated is conveyed through an electrode array where alternating energy causes polar molecules in the material to continuously reorient them to face opposite poles much like the way bar magnets react in an alternating magnetic field. The friction resulting from this molecular movement causes the material to heat both rapidly and uniformly throughout its entire mass.
