In the same way, the dielectric heating technology is extremely interested in the heating technology because a form of thermal energy is directed into the dielectric material with appropriate frequency range. Consequently, this technique has no effect on another material such as the rice. The dielectric heating structure uses the frequency spectrum principle, which is applied in the form of an electric field to transfer power into the dielectric material with polar molecule. The resonance of the molecules is quickly and evenly occurred in the dielectric material and dielectric heating. The dielectric heating is currently being applied in many applications [4]-[6], which are dehydration industry, fruit pre-serration industry. In addition, the dielectric heating can be used for the organism or pests in the agricultural sector. Because of the structure of an organism is a liquid or a polar molecule, it can induce the radio wave to heat [7], [8]. The organisms are embedded in the products that are rice weevil, insect, pests, and worms, which have an effect on the export or the imported product. The plate heating technique uses a plate to generate the electromagnetic wave to the medium. As a result, the dielectric is heated up by using the nature of the electric field that is distributed between the plates.
