Non-Invasive Sterilization by Intense Pulsed Light ( IPL ) or by Sharp High Voltage Pulses ( PEF ):
Non-Invasive Sterilization by Intense Pulsed Light ( IPL ) or by Sharp High Voltage Pulses ( PEF ):
We were first to publish in 1991-2001 on mechanisms of PL sterilization / purification and as proven experts offer to develop your IPL applications with ready to ship systems as below :
now are discounted & spare UV flash lamps . info @ wek-tec . de < automatic & analogue >
Our PL bench-top systems were used at many R & D labs and cited in various industrial and peer-reviewed publications .
IPL effectiveness increases proportionally its pulse power w / cm ² & its UV content to the point where bacteria & spores are fully disintegrated .
IPL fully sterilises clear liquids in transparent packs as it was proven on our IPL system by Baxter Corp . ( USA ) with UV resistant spores of B . Pumilos . Our business restructuring allows to sell out pilot and R & D systems listed here
The PEF pilot on the left provides a high-indemand dual capability by 3 sets of processing chambers
• coaxial PEF chamber for liquids with changeable gaps ,
• colinear PEF chamber to form volume discharges in juices .
• 12L batch volume with controlled juice heating / cooling ,
• flat PEF chamber with 14cm round ground and HV electrodes and a variable gap between both of 0.5-3cm .
and broad fixed & gradually changed pulsing :
• positive rectangular pulses 2,5-50 µ s at 4Hz to 500Hz ;
• el . fields 5-65kV / cm by our 25kV 2kW pulser ;
• pulsing time 1s-1h ,
• convenient LED lighted control panel . Please click on its photo to get its pdf brochure .

Dual PEF Pilot to sanitize juices or to extract juices or colours from hard vegetative cells of grass , roots , etc .
PEF sterilizes juices by 1 of 2 different processes : 1 : by electrical stretching bacteria only up to its ruptures or 2 : by creating volume el . discharges in a co-liner chamber where free electrons destroy both bacteria and spores .
