Pulsemaster PEF Systems

Pulsemaster is a Dutch-German engineering company specialising in pulsed electric field (PEF) processing for the food industry, with production in Hapert, the Netherlands, and an office in Lohne, Germany. Its team has designed and built more than 70 PEF systems since 2009, helping processors cut energy, water and time in cutting, drying and extraction steps.

PEF applies very short high-voltage pulses that open plant and animal cell membranes without heating the product. Pulsemaster systems use Marx solid-state pulse generators with up to 100 kW per system and up to 1,000 pulses per second. Main uses are French fries and crisps, where softer tubers cut cleanly and absorb less oil, plus vegetables, fruit juice, plant and seaweed extracts, meat, fish, dairy and sugar processing. Systems run in Europe, North America, Australia, India and China.

• Solid-state pulse generators: Marx-type generators deliver up to 100 kW and 1,000 pulses per second.
• Compact PEF system: all-in-one unit with a small footprint for small and mid-sized lines, up to 10 tonnes per hour.
• PEF Belt Unit: treats large raw-peeled and skin-on potatoes on a conveyor belt.
• Liquid treatment: chambers for juices, beverages and other pumpable products.
• Extraction support: improves yield of plant, seaweed and protein extracts.
• Global support: export service and compliance with regional certification standards.

• Snack and frozen fry makers in Vietnam pretreating potatoes and sweet potatoes before cutting and frying.
• Fruit juice and puree producers improving juice yield and extraction.
• Dried fruit and vegetable processors shortening drying times for mango, jackfruit or cassava.

• Better cutting: treated potatoes cut with less starch loss, feathering and breakage, which raises yield.
• Less oil and energy: smoother surfaces and controlled moisture release allow shorter frying times and lower temperatures.
• Faster drying and extraction: opened cells release water and compounds more easily, saving time, energy and water.
• Scalable lines: compact units handle up to 10 tonnes per hour and larger systems up to 100 tonnes per hour.

Food processors face rising energy and water costs and pressure to reduce oil content and waste, so non-thermal pretreatments such as PEF are spreading beyond European fry plants. Growing snack, frozen vegetable and fruit processing capacity in Southeast Asia creates demand for equipment that raises yield while cutting energy use.

Dutch-German company with production in Hapert, the Netherlands, and a German market office in Lohne (Oldenburg). More than 70 PEF systems designed and built since 2009; potato-industry installations in Germany, the US, Canada, the Netherlands, Belgium, Austria, Australia, India and China. Exhibited at Anuga FoodTec 2024, Interpom 2024 and SNAXPO 2025.
