Electrostatic separation of hexane de-oiled soy resulted in a higher true protein content (59.6 ± 0.1 %DM) than previous studies after correction to a protein factor of 5.7 (53.5 %DM and 51.4 %DM; Appendix table A1) (Kuspangaliyeva et al., 2023; Xing et al., 2018). This might have been caused by a combination of (a) the higher driving force to ...

In other words, electrostatic separation can only be successful if the individual grains consist only of one component [34]; however, as shown in Figures 5 and 6, the studied material is composed ...

Working Principle of Electrostatic Separators. The electrostatic separation process involves the utilization of electrically charged surfaces to separate mixed particles. Initially, the particles are fed into a charging unit where they acquire an electrical charge. The charging method can either be triboelectric or corona discharge.

Abstract.
