Abstract

PEF sterilization technology is a novel non-thermal sterilization technique, the processing chamber is applied directly, for loading the material to be processed in a processing chamber and pulsed electric field. A paper designed pilot scale electrode spacing is adjustable, replaceable processing chamber cavity coaxially novel process chamber, the system established by pulsed electric fields coupled three COMSOL software mathematical model of the electric field intensity of the processing chamber, the material flow characteristics and temperature distribution, provide the basis for structural optimization coaxial treatment chamber. Simulation results show that non-uniform electric field strength at the edge of the inner circle of the positive electrode, the positive electrode treatment chamber after rounding is more applicable.
