Expanding Non-Invasive Food Sanitations :
Pulsed Electrical Fields for filtered juices and for modifying foods while preserving its nutrition properties with our dual PEF pilot system :
for R & D :
• 3 x PEF coaxial chambers for liquids to choose from with 3- , 4- and 5-mm gaps , 12L batch with a circulation pump , L / min meter . Co-linear PEF chamber- optional ;
• flat PEF chamber for vegetative staffs for an PEF assisted extraction of juices or organics softening .
for production : two in line coaxial chambers at same or different pulsing parameters in a batch or direct flow-through processing .
This PEF pilot is NOW at the 35 % discount !
Control panel : With reliable analogue controls to select from the industry one of broadest choices of pulse parameters :
• Pulse rates : 4-500Hz at Pulse widths : 2,5-50 µ s ;
• Electrical fields 5-55kV / cm ; optional- to 75kV / cm
• Pulsing Timer : 1s-9h ;
• 25kV 2kW pulser , options - up to 10kW ;
Process controls :
• Meters for pH , T ° C , TDS ( total dissolved solids in ppm ) and el . conductivity ( in µ S / cm ) with LCD displays at the controller , 2kw heater in the batch for adjusting juices conductivity with T ° C .
• Digital scope to control voltage and current pulses
Pulse shapes :
• positive rectangular ,
• fronts / tails ~ 1 µ s ;
• ~ 10 % flat at 50 µ s
Up to 50 µ s long pulses at very high el . fields along with selected pulse rates , adjusted juice conductivity by its T ° C will insure efficient deactivation of bacteria by PEF .
The system material & dimensions : W-79cm , H-100cm , wheels with stoppers ; B-59cm ; Food grade stainless steel , PA6 insulators , ca . 70kg . Electrical : 1 phase 230VAC , 12A , 2kW , EU plug
PEF sterilizes by stretching bacteria up to its ruptures by strong and sharp high electrical fields . It is also used for breaking vegetative cells to ease its juice extraction or for softening solid foods : details .
Our PEF parameters fit many published sources with up to 5 logs inactivation of bacteria in juices at up to 250l / h and respectively less at 500l / h . The actual inactivation depends on all juice properties , such as its el . conductivity , pH , the total dissolved solids ( TDS ), its nutrients , types of bacteria , etc . It ’ s broad PEF parameters allow finding optimal production conditions for larger systems or using it for smaller production .
We offer to find optimal PEF parameters for your juice sanitation or for PEF assisted juice / nutrient extraction from roots , grass , etc ., or for softening hard meats , etc . with our flat PEF chamber .
PEF vendors are already present on the market yet under pressure to reduce costs while increasing the process flexibility with broader PEF parameters . Our new dual PEF pilot is to meet this request .
