MACROWAVE™ PASTEURIZATION SYSTEMS ASSURE UNIFORM, VOLUMETRIC HEATING
HOW RF HEATING WORKS
In a Radio Frequency heating system the RF generator creates an alternating electric field between two electrodes. The material to be heated is conveyed between the electrodes, where an alternating energy field causes polar molecules in the material to continuously reorient them to face opposite electrodes much like the way bar magnets move to face opposite poles in an alternating magnetic field. Friction resulting from this molecular movement causes the material to rapidly heat throughout its entire mass.
The illustration below depicts a radio frequency drying system with material between the electrodes. Polar molecules within the material are represented by the spheres with plus (+) and minus (-) signs connected by bars.
The amount of heat generated in the product is determined by the frequency, the square of the applied voltage, dimensions of the material and its dielectric loss factor which are essentially measures of the ease with which the material can be heated by radio frequency waves.
The very rapid and precisely controllable RF heating process offers the advantages of reduced processing times, consistent quality, and simplified process control.
Founded in 1946, Radio Frequency Company specializes in developing and manufacturing high frequency heating systems to improve efficiency in many industrial applications. RFC is a technological leader in the development of R.F. heat processing systems and is known for the highest standards of quality in equipment and service.
