NON-INVASIVE up to absolute STERILIZATION
by Strong Pulsed Electrical Fields of juices & wines or honey & creams keeping unchanged its properties with our scalable pilot production system , ready for your evaluation :
• for R & D : 1x PEF chamber for solids & creams and 1x coax PEF chamber for liquids ;
• for pilot production : two in line coaxial chambers at same or different optimally enhanced pulsing using batch or direct flow through processing .
Broadest changeable SPEF parameters :
• Pulse rates in Hz : 4 , 20 , 100 , 500 , 4-125 ;
• Pulse lengths in μs : 2,5 , 5 , 10 , 50 , 2,5-20 ;
• electrical fields 5-50kV / cm ;
• selectable pulsing time 1s-9h ;
• 25kV 2kW pulser , up to 10kW options ;
• overcurrent protection is build-in with a reset ;
• convenient in use , simple to maintain , safe !
Pulse shapes :
• positive rectangular ,
• fronts / tails ~ 1 µ s ;
• ~ 5 % flat at 50 µ s : V ( t ) & I ( t ) at 25kV >
PEF sterilizes by stretching bacteria up to its ruptures by electrical fields with 20- 50kV / cm strength delivered by sharp square pulses : more in details .
Inactivation of bacteria in juices with this system can reach 3-6 logs at 250l / h and 2-4 logs at 500 l / h with one or both coax chambers . Plus , its unique set of broad pulsing values with up to 50kV / cm fields allows finding optimal parameters for your future cost-effective production system .
Wek-Tec offers to evaluate or to develop your optimal PEF process which work can be credited to your possible purchase of our system . This work is done at our place with a bio-support from a local certified food lab .
Our Pilots and lab R & D systems have been successfully used past 23 years worldwide and brought valuable scientific results referenced in various academic and in industrial publications .
