Patent ID: 7059269

Claim:
A pulsed electric field processing system for treating a dielectric sheet material, comprising: a pulsed voltage generator for generating a pulsed voltage with positive polarity; control means to provide control signals to said pulsed voltage generator for activation and deactivation thereof; first sensing means for sensing a leading edge of said dielectric sheet material; and second sensing means for sensing a trailing edge of said dielectric sheet material, wherein said control means activates said pulsed voltage generator in response to the first sensing means sensing the leading edge, and deactivates said pulsed voltage generator in response to the second sensing means sensing the trailing edge; a first electrode receiving the pulsed voltage of the pulsed voltage generator; a second electrode connected to ground; a single dielectric plate arranged between the first electrode and the second electrode, wherein the dielectric plate and the first electrode are spaced apart to provide an open gap between a surface of the dielectric plate and a surface of the first electrode for receiving the dielectric sheet material, said dielectric plate having a uniform surface profile; and at least one transport assembly for transporting the dielectric sheet material through the gap, wherein the dielectric sheet material is exposed to a pulsed electric field in the gap.
