Continuously pulsed electric field treatment chamber modelling and design

Abstract

The perspectives of pulsed electric field (PEF) application for rheological changes in plant materials and treatment chamber design are considered in current paper. By using some mathematical tools and experiments data, viscosity of transporting plant materials confirms proposed Bingham rheological model assumption. Experimental studies have shown the presence of structure formation in material supplied to the treatment chamber channel. An effect of PEF treatment, with changes of material structure and increasing of material plastic viscosity from 0.117 to 0.159 Pa·s for samples after treatment by a field strength of E = 8 kV/cm and the number of pulses n = 300 was found. Obtained results of pulsed electric fields application in continuously material flow can be used in pulsed electric fields technologies, equipment design and help to determine cost efficiency of treatment in industrial application.

Experimental Analysis of the Influence of Inter-Electrode Distance in Juice Extraction Processes Using Pulsed Electric Fields

“…In addition, the number of pulses must be optimized in order not to consume too much energy. The distribution of the electric field in the treatment chamber is another parameter to be taken into account in order to improve the efficiency of the PEC extraction processes (Knoerzer et al, 2012;Shorstkii et al, 2019;Arshad et al, 2020). Thus, in this paper, we will focus on another factor that can also have an influence on the yield, namely the inter-electrode distance in the process chamber.…”
