Non-Invasive Sanitation with PEF & IPL :
Dual Pulsed Electrical Fields Pilot to sanitize juices or to soften organics
Processing Hardware :
• coaxial PEF chamber for liquids with replaceable central electrodes for 3- , 4- and 5-mm gaps .
• colinear PEF chamber to replace a coaxial chamber to form volume discharges in juices .
• 12L batch volume with controlled juice heating , a circulation pump , valves to switch between direct and circulation flows .
• flat PEF chamber with 14cm round ground and HV electrodes and a variable gap between both of 0.5-3cm . Its electrical connection can be in a minute switched from a coaxial chamber . The flat chamber is for PEF assisted juice extraction from leaves , roots or for softening hard roots or meats .

Pulse shapes :
• positive rectangular ,
• fronts / tails ~ 1 µ s ;
• ~ 10 % flat at 50 µ s
Controls :
• flow-rate , pH , T ° C , TDS ( in ppm ) and conductivity in mS with LCD displays .
• Digital scope to control pulse shapes .
PEF sterilizes juices by 1 of 2 very different processes :
1 : by stretching bacteria only up to its ruptures by 20-40kV / cm electrical fields generated by short pulses in coaxial chambers ;
2 : by creating volume electrical discharges in a co-liner chamber so its discharge electrons collide with both bacteria and spores till its full deactivation . It requires increasing juices conductivity e . g . by a controlled preheating of juices . Details .
