An ohmic heater also known as a joule heater is an electrical heating device that uses the electrical resistance of the liquids to generate heat, that is produced directly within the fluid itself by Joule effect, as alternated electric current passes through a conductive material. This has the result of transform energy causing a temperature rise. The most commonly used heating techniques for liquids rely on heat transfer from a hot surface. This heat can be generated directly from an electrical heating element or indirectly from a hot means of transportation (e.g. steam) via a heat exchanger (e.g. shell and tube ,plate). These methods require a temperature gradient to transfer the heat to the process liquid, therefore, the surfaces are at a higher temperature than the product.
