Non-Invasive Sterilization by High Voltage Pulses ( PEF ) & Intense Pulsed UV Light ( IPL ):
Non-Invasive Sterilization by High Voltage Pulses ( PEF ) & Intense Pulsed UV Light ( IPL ):
The PEF pilot on the left provides a high-in-demand 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 haard 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 . Details :

Our PL bench-top systems were used at many R & D labs and cited in various industrial and peer-reviewed publications .
< the automatic & analogue > now are discounted along with its spare UV flash lamps . The effectiveness of IPL increases with its pulse power & its UV content to the point where bacteria & spores are fully physically disintegrated .
IPL fully sterilises clear liquids in transparent packs as it was proven on our IPL system by the Baxter Corp . ( US ) with UV resistant spores of B . Pumilos .
We offer to sell all know-how information on our PEF and PUV pilots plus on already sold or just developed UV tunnels . Please click on images to find more or inquire at https :// www . wek-tec . de
This Vortex batch pilot to sanitize powders . Results from this Vortex can be used to construct our already designed flow- through system for photo-chemical processing of up to 100kg / hour powder .
R & D Vortex can effectively modify organic powders by UV . Example : D2 vitamin enriching in mushroom powders with its partial sanitation by moving treated powders around a UV ( PL ) lamp by a Nitrogen enriched air flow to exclude oxidation .
We were first to publish in 1991-2001 on mechanisms of PL sterilization / purification .
