The microwave dielectric heating
phenomenon is a result of physical interaction between an electromagnetic field with the matter irradiated and characterized via intrinsic dielectric properties.
is considered the fourth type of heat transfer (Koumoutsakos 2001).
The dielectric properties for a wide range of food and agriculture commodities have been recorded; the dielectric properties of foods are temperature dependent [1, 6], studies must be conducted over the wide range of temperatures experienced by the product during thermal processing if dielectric heating
behavior is to be precisely predicted.
The RF dielectric heating
system with the pilot-scale RF heater of 1.
Recently, dielectric heating
is under the radar for pasteurizing in shell eggs as they employ volumetric heating principle.

Now it might be possible to eliminate pathogens in the seeds of sprouts by using radio frequency (RF) dielectric heating
This article discusses the use of automation and provides information on the choices in dielectric heating
equipment and on methods for making the process function more effectively.
Litzler, Cleveland, OH, announced that PSC, a manufacturer of radio frequency and dielectric heating

A major face of each web is placed into engagement with the opposite major faces of the mat and then put in a dielectric heating
assembly with conductive die electrodes in a predetermined pattern.
Researchers are developing dielectric heating
techniques that use microwave or radio frequency (RF) energy to dry bulk materials.
The properties like dielectric permittivity, dielectric loss, conductivity, dielectric heating
coefficient, and absorption coefficient were evaluated.
Along with ultra high frequency electromagnetic wave heating, microwave heating is called dielectric heating
Scientists are examining the capacitive dielectric heating
of seeds embedded in edible films as a way to greatly reduce the chance of spreading foodborne illness through sprouts.
For the past 40-plus years, Nelson has explored using radio-frequency and microwave dielectric heating
to dry grain.
