Macrowave systems are suitable for batch or conveyorized applications for bagged or bulk product. In the heating system, a radio frequency (RF) generator creates an alternating electric field between two electrodes. The material to be treated is conveyed through the electrode array, where this alternating energy causes polar molecules in the materials to continuously reorient themselves to face opposite poles, much as magnets behave in an alternating magnetic field. The friction resulting from molecular movement causes the material to heat rapidly and uniformly throughout its entire mass. The pasteurization systems operate at 40 MHz, where the depth of penetration and uniformity of heating are optimized, thereby ensuring effective microbe kill and avoiding deleterious effects on product quality.
