Non-Invasive Sterilization by High Voltage Pulses (PEF) & Intense Pulsed UV Light (IPL):

November 21, 2024

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 2,5-50µs at 4Hz to 500Hz;
  • el. fields 5-65kV/cm by our 25kV 2kW pulser;
  • pulsing time 1s-1h,
  • convenient LED lighted control panel.

Dual PEF Pilot to sanitize juices or to extract juices or colours from hard vegetative cells of grass, roots, etc

The brochure of its small table-top version is here.

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:

 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.

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.
