dielectric heating

This term describes a specialized industrial process used primarily for drying or curing materials that do not conduct electricity. It is characterized by the use of radio-frequency energy to generate heat internally, rather than relying on external heat conduction or convection. This allows for uniform heating throughout the bulk of the material, preventing the surface from overheating while the core remains damp.

In technical discourse, it is often contrasted with conventional heating methods. Because it targets polar molecules, such as water, it is highly efficient for moisture removal in wood, plastics, and certain food products. The term is strictly technical and is used almost exclusively in engineering, materials science, and industrial manufacturing contexts.
