Pulsed Light ( PUV ) and PEF customized processes & systems to sterilize or modify various solid , liquid or powdered food products
have been developed / delivered by wek-tec with its cooperating German companies since 1996 . Obtained results have been published & referenced in various scientific and industrial publications partially presented on the wek-tec website in info . Example :
For Pulsed Electrical Fields -PEF :
Getting cost-effective PEF processes aside from simplest cases of clear juices also requires the development stage to try various pulse parameters to get a costeffective process and reliable simple equipment .
The important advantage of our customization is in employing very broad pulsing parameters as on the adjusting left page . Please , review and send us your requirements for our first evaluation .
Dr . Alex Wekhof was first already in 1999-2001 to publish on sterilization mechanics for the intense pulsed light . It is summarized in the left chart and allows finding energy regions with optimal ratios of UV energies to its costs . It is the base for our analysis of each customer case , where we determine where the use of intense PL is superior to the continuous UVC light , or to PEF or to non-invasive IR .
We welcome your requirements for our equipment and / or process development
