Dual Duty Pasteuriser

Dual Duty Pasteuriser

The dual duty pasteuriser is a fixed skid housed within the secondary processing laboratory of the BEACON Pilot Plant Facility at IBERS Gogerddan, Aberystwyth. The pasteuriser was designed and built specifically for the BEACON project.

Technology summary:

The key features are:

  • Dual duty: capable of running at 50 litres/hr or 500 litres/hour.
  • Capable of rapid pasteurisation raising feedstock temperature from 15°C to 80-90°C with twin holding coils to hold feedstock for 15 seconds.
  • Able to cool from 80°C to 20°C in one pass. 100 litre batch tank or can be linked to larger reservoir for continuous running.
  • Centrifugal feed pump (three phase 0.37kW) with stainless steel contact parts, duty 1000 l/hr at 1.5 bar g.
  • Centrifugal hot water recirculation pump (three phase 0.37kW) with stainless steel contact parts, duty 2000 l/hr at 2.0 bar g.
  • Temperature and flow sensors with data acquisition and collection using a Grant Squirrel data logger.
  • Tri-clamp connectors.


  • Pasteurisation of liquid feedstocks to minimise of microbial loading
  • Rapid denaturing of heat labile proteins in liquid feedstocks prior to centrifugal separation.
  • Pasteurisation of post-fermentation liquors.
