Project at a Glance Contents on the CD ROM
  • A Technology which capable of processing  food products by converting electric current into heat.
  • Also known as Joule Heating or Resistive Heating.
  • Process involves passing an electric current through the product and in combination with the electrical resistance of the product generates heat in a uniform fashion. Most food products can be heated using Ohmic heating.
  • Ohmic heating can feature a higher energy efficiency, rapidity, uniformity in heating pattern, and cleanability.
  • Benefits are reduced burning, fast processing times, energy efficient, low maintenance.
  • Increasing the rate of freeze-drying up to 25 percent, a significant time and energy savings for processing.
  • A useful tool for value-added processing, and it has great potential for use in a wide variety of food processing operations involving mass transfer.
  • Ohmically heated the Rice bran and also useful in extracting the oil which   yielded more total lipids from rice bran.
  • The whole egg was heated by Ohmic heating at frequency of 20khz.
  • The Ohmic heating process  provide food processors with the opportunity to produce new, high-value-added, shelf-stable products with a quality previously unrealized with current sterilization techniques.
  • Electrical conductivity of all products increased linearly with the temperature during the Ohmic heating at constant voltage gradient.
  • Additionally Ohmic heating can be used in non-food applications such as the processing of sludges and slurries with a high solids.
  • The potential application could be thermal process of meat products, dairy processing, pasteurization\ sterilization of liquid foods, tomato peeling, and fermentation.
  • Optimization of capital investment and product safety as a result of high solids loading capacity.
