What Is The Process?

Normally a two stage operation with a low and high phase through a two stage heat exchanger.

The heat exchanger has 6 ports (3 inlets and 3 outlets). 1 inlet and outlet are used for the product to flow through, another is used for ambient water to flow through to cool the product from as high as 95°C to above the ambient cooled water temperature.

The third inlet and outlet has chilled water flowing as low as -2C to cool the product to its required end temperature.

The regeneration or reclaim area uses the heated pasteurised material to heat the incoming material so to reclaim the waste energy.

To create a product such an Ice-Cream, yoghurt or drinks.

Pasteurisation Application Considerations

  • Does it have a two stage heat exchanger?
  • What is the temperature of the high stage water required?
  • What is the return temperature high stage water?
  • What is the temperature of the chilled water required?
  • What is the return temperature of chilled water?
  • What is the flow rate of chilled water?
  • What is the pressure drop through heat exchanger?
  • What is the type of fluid used?

Why Is Cooling Required For The Pasteurisation Process?

Ambient water temperature to cool product from high to medium temperature.

Chilled water to cool to low end temperature.
