Mark de Boevere

International Potato Processing & Storage Convention (IPPSC) 2015

  • PEF

Mark de Boevere from Pulsemaster delivered a comprehensive overview of the latest advancements in the development of Pulsed Electric Field (PEF) equipment at an industrial scale for potato processing. His presentation was titled “Systems Using Pulsed Electric Field (PEF) Technology – An Excellent Alternative for Preheaters in the Potato Industry.”


The presentation effectively highlighted the benefits of Pulsed Electric Field technology, detailing enhanced sugar extraction levels, improved cutting, reduced feathering, and a smoother cutting surface. It also emphasized reduced frying time and improved texture and crispiness of potato products. Potatoes processed with Pulsed Electric Field become more homogeneous, evening out the structure and consequently reducing seasonal variation.

The audience engaged actively, posing numerous questions about the pulse generator principles Pulsemaster employs in manufacturing turn-key PEF systems for the industrial processing of solids like potatoes to produce French fries and crisps.
