Description of the innovation 

What is new is that pulsed electric fields is a purely physical treatment of the potatoes, with no significant increase in temperature of the potatoes. On the inside of the cell wall is a membrane, which holds the contents together. Electric pulses are used to drill miniscule holes in the membranes of the potato cells. There is nothing chemical about this process, it is a purely physical treatment of the membranes of the potato cells and gives great benefits to product and process. The actual treatment of the potatoes in the electric field is within one second.

 

Added value for the user

By drilling holes in the membranes with pulses, the cell pressure decreases in the potato. As a result, you cut much better, have a much nicer cut, the fries do not break as easily, they are smoother, they absorb less oil so you use less oil. A PEF treatment facilitates the extraction and evaporation of moisture. You can reduce your blanching and frying time. The yield is also higher because less potato starch is lost and there is less breakage of the fries. Other benefits include better texture of the fries. Also, the fries are crispier. Difficult cut shapes such as corrugated, waffle and lattice are now easier to cut and with less cutting loss. A PEF system is compact and easy to control. When the PEF system is turned off, the process stops immediately. Compared to a pre-heater, significantly less product is lost in the event of an incident or malfunction. Only at the moment of making the pulse do you use energy. There is no constant use of energy. You can produce more French fries and potato chips with less energy.

 

Added value for the further sustainability and professionlalization of the potato sector:

Through the application of pulsed electric fields, Pulsemaster PEF technology meets the potato processing industry's need for natural and clean processes that can greatly reduce energy and water consumption.
