The Macrowave™ Pasteurization System uses a high frequency electric field proven to effectively control pathogens. Utilizing clean electrical energy from the grid, the material to be treated is conveyed through a high frequency electrode array where the alternating electrical energy causes the material to heat rapidly and uniformly throughout the product thickness. Radio frequency (RF) heating is a highly efficient, "direct" form of heating that does not waste energy when heating large volumes of air or preheating the system itself. Company has developed systems that operate at 40MHz where the depth of penetration and uniformity of heating are optimized, ensuring effective microbe kill and avoiding the harmful effects on product quality from prolonged exposure to high temperatures. These systems are available in conveyorized or batch configurations.
