Radio Frequency Pasteurization:
The Wave of the Future in Food Pasteurization
Founded in 1946, Radio Frequency Company (RFC)’s 40,000 sq. ft. design
and manufacturing facility is located in the suburbs of Boston alongside the
historic Charles River. RFC is a global manufacturer of advanced industrial
radio frequency (RF) processing systems for the rapid heating, drying,
disinfestation, and pasteurization of food products and ingredients.
Today, RFC’s Macrowave™ pasteurization systems are treating more than
500 million pounds of food ingredients, both for humans and pets, per year.
Unlike irradiation and other
treatment methods, RF treatment is certified organic, natural, and can be used on an FDA-approved clean label. In an RF
pasteurization system, the RF
generator creates an alternating
electric field between two electrodes, above and below the
system conveyor, which causes
the treated product to heat rapidly and uniformly throughout its entire thickness, whether it is processed in bags, or in bulk on a troughed conveyor. This
rapid and volumetric heating means that there is no temperature differential
from the surface to the center of a product and no prolonged soak time that
can damage functionality and other organoleptic qualities. All Macrowave
systems meet FSMA standards for a preventive control step and incorporate
the HACCP monitoring, data logging, and alarm functionality required for a
kill-step validation. Treatment systems are available in a broad range of sizes
to suit individual customer requirements and are designed and constructed to
GMP standards for food safety and ease of sanitation. All Macrowave systems
are UL approved, FCC certified, and EU compliant. For all systems deployed
domestically or internationally, RFC maintains a complete spare parts inventory; factory-trained RF service technicians are available 24/7. RFC’s MacroCare
Preventive Service Plan assures customers that their system is operating at
peak performance, minimizing downtime and maximizing their ROI. Because
RF treatment is a USDA Organic thermal process and is easy to own and operate, it’s no wonder why RFC’s Macrowave pasteurization systems are truly
“the wave of the future” in food safety.
