PEF systems
for the food and beverage industry
Pulsemaster has the answers for maximizing the effect of your raw materials and enhancing food quality and safety. Under the brand name Conditioner we manufacture a range of industrial systems to meet our customer’s production requirements. These turnkey solutions are fully integrated and modular systems for either cell disintegration of solids or microbial inactivation of liquids.
The typical average power range of our industrial pulsed electric field systems is up to 100 kW and the pulses are applied at repetition rates of up to a maximum of 500 pulses per second to allow sufficient treatment of all volume elements.
As a continuous short-time process with low space requirements, pulsed electric field processing systems can easily be implemented in existing lines.
Cell disintegration of solids
For cell disintegration applications a typical processing line consists of a transport system, a treatment tank unit, a transformer unit and a pulse generator unit. Our range of systems for cell disintegration of solids like fruit, vegetables and potatoes allows processing capacities of 1 to 60 tons per hour (132,000 lb/h) per system. Pulsemaster’s largest industrial sized PEF equipment up to 150kW per system, allows processing capacities as high as 198.000 lb of potatoes per hour (90 tons per hour) to meet the growing demand for higher input capacities in potato industry. All of which results in improved output of French fries in lb/h or tons per hour, reduced costs of ownership and higher product quality. The belt transport systems are an optimum solution for the treatment of potato tubers, roots, vegetables and fruits.
Microbial inactivation of liquids
For mild preservation of beverages and other (semi)liquids a typical processing line consists of a supply tank, a fluid pump, a transformer unit, a pulse generator unit, a cooler (if required) and a buffer tank. The capacities of our systems vary from 30 liters (8 US gallon) up to to 5000 liters (1320 US gallon) per hour per system. Flow, temperature, and energy delivery are constantly measured.
Processing raw milk, cheese-making milk, yoghurt drinks or whey, using Pulsemaster’s pulsed electric field treatment enables the inactivation of the microbial cells, resulting in an extended shelf life and retention of fresh taste and healthy compounds. Pulsemaster’s PEF-technology uses low temperatures to ensure that freshness and precious, natural nutritional value are retained, achieving a higher probiotic value.
Shelf life increase
Pulsemaster’s proprietary PEF-technology can be used to treat fresh juices and smoothies. By permeabilizing cell membranes of micro-organisms PEF enables a targeted shelf life increase, retaining product quality and freshness. Pulsmaster’s juice applications reflect the value of Pulsemaster’s PEF-technology in achieving microbial cleanliness while simultaneously retaining the inherent qualities of the product. Agreements can include the supply of Liquid handling equipment to complete the project.
Enhanced extraction from fruit mashes and vegetables
Our range of systems also enables enhanced extraction of vitamins, colour and antioxidants from fruit mashes and vegetables, as well as achieving an increased yield of juice.
Pulsemaster Conditioner
Unique features
Marx solid-state generator operation principle is discharge of capacitors in series. The stored energy is discharged into a well defined load (treatment chamber). Switching in series gives a fast rise time of the pulse, which is necessary for an effective PEF treatment. A fast rise time, is a unique feature of our concept.
In addition, Pulsemaster has developed innovative switching power supplies that utilize advanced capacitor charging technology that enables our systems to be significantly more reliable than comparable products. Advantages are Operator safety, improved modulator reliability and pulse-to-pulse control.
Power range
Our robust Marx solid-state typology enables better pulse control and high reliability. Pulsemaster can supply a range of robust PEF systems, covering a wide power range up to 100kW per system. The design of these tailor-made pulsed electric field systems is compact and modular for easy integration and power upgrade. Our industrial PEF systems are not only easy to use, but also easy to service and maintain, thanks to the modular design with field replaceable units.
Our highly skilled engineering experts have deep knowledge and industry experience in designing and building over 70 PEF systems since 2009 for a broad spectrum of applications and outputs in the food industry worldwide. The applied pulse generators have a proven track record for food industry and research applications.
Marx solid-state typology pulse generators
The use of Marx solid-state, high voltage pulsed power systems for PEF processing is the key to commercial applications. Solid-state technology allows this pulsed electric fields technology to scale from pilot-scale batch units for research applications to large-scale food processing systems as demonstrated by the commercial adoption of PEF with over 70 Marx solid-state typology systems installed worldwide since 2009.
Highest quality engineering
All PEF systems used by industry to make French fries and crisps, built according to Marx solid-state typology and running succesfully in potato industry in Germany, US, Canada, The Netherlands, Belgium, Austria, Australia, India and China, technically originate from the work of Pulsemaster’s highly qualified team of German engineering experts.
