Never published movie of the PurePulse Pilot facility line of Cool Wave Processing b.v. (CWP, www.cwp-bv.nl) located at the R&D facilities of TOP b.v. in Wageningen. This system (100 - 600 L/hr) is used to evaluate electrical components and of course to conduct application oriented research (shelf life, quality, taste, etc.) in the period 2007-2011.

This -never published before- movie was orignially only recorded to illustrate the PEF 2.0 process to potential costumers of CWP, product developers and scientists and colleagues at the office. Hence, for internal purposes only. The product development and engineering project was started in the period 2007-2008 in good collaboration with the engineers from CWP b.v. and food science experts of TOP b.v. (www.top-bv.nl). The final design details of the PurePulse system-including details of the treatment chamber- are not recorded and kept confidential.

Cool Wave Processing meanwhile engineered during the period 2009-2011 the full industrial PurePulse lines (currently 600, 1200 and 1800 L/hr). Ludo van Schepdael was the senior project leader responsible for the engineering project. The developed industrial PEF 2.0 systems consists of (a) a PurePulse system and (b) a fully functional pump and heat exchanger skid. Such a production line needs to be coupled with a CIP system and a correct filler. (more information via info@cwp-bv.nl)

Due to the breakthrough technology of CWP it's possible to cold pasteurize liquid products like juice and milk at temperatures far below 50oC (fraction of seconds) using high voltage pulsing fields.

I do expect that this PEF 2.0 technology will be adapted quit rapidly in the next 10 years. I also think that this technology will compete with pascalisation/HPP due to a better cost per liter of product. PurePulse is an very good example of a modern electricity based . process (http://wdeheij.blogspot.com/p/technol...).

PS all colleagues at the office and at CWP did have great fun when they listened to my English-English voice over ;-) . The beautiful lady in the movie is our colleague Myriam Knopf (food & health expert, WUR).
