SteridealĀ® Ohmic

JBT Ohmic heating of foodstuff is the application of high voltage to the product flowing inside an aseptic sterilizer.
The liquid food reacts as an electric resistance and generates heat by the Joule effect. The higher the voltage and the food electrical conductivity, the higher and faster the delta temperature achieved.
The major advantage of ohmic heating is obtained in dice processing: the product quality is better compared to standard heating technologies since the centre of the dice is heated at the same velocity as the liquid carrier, so preventing parts of the product from overheating.
Excellent for all kind of products:

  • Liquid, semi liquid, concentrated and high viscosity products
  • Containing fibers, small cells and featuring high viscosity such as puree and soups
  • Thermo sensitive products
  • Fruit preparations and fruit jam with dices
  • Soup and sauces
  • Ideal for large size particles, 50-70 mm
