Laboratory setup for converting mains voltage into a pulsed electric field with automated monitoring and control systems

Abstract

This paper describes a setup that converts mains voltage into a pulsed electric field (PEF) with a wide range of frequencies, pulse duration and tension in the layer of the processed material. The use of digital technology and inline batch processing enables automated reporting of processing times (exposures); loading and unloading of the process chamber. Monitoring of the chamber processes and feedback from the control unit automatically maintains the PEF parameters required for processing in accordance with the calculated dose. The proposed device with the removable process chambers can process both bulk materials and vegetable raw materials in the fermentation process to improve the taste as well as the organoleptic properties of the resulting products.
