ABSTRACT
ElectroheatingTM, also called ohmic heating, resistance
heating, or Joule heating, is based on the passage of alter-
nating electrical current through a biological fluid that
serves as an electrical resistance. The electrical current is
passed along or across a flowing fluid, and the electrical
power introduced into the product is translated into
The advantage of Electroheating over conventional heat-
ing is the departure from the limiting heat transfer coeffi-
cient and the need for high-wall temperatures.
Electroheating is a novel technology for heating fluids in
the food, drug, and biotechnology industries for the purpose
of sterilization and pasteurization, providing fast heating
rates, more uniform heating, and improved product safety
and quality.[3] It overcomes problems of fouling and forma-
tion of off flavor and color formed in heat exchangers. The
electroheating technology enables unprecedented rapid
heating to very high temperatures, permitting very short
holding time.
