Electrostatic separation – a novel dry separation process for food ingredients Conventional dry separation processes, such as air classification and sieving, use differences in particle size and/or density as driving force. However, particles with different compositions may be milled to similar sizes, which limits the

Air classification and electrostatic separation of finely ground and SC–CO 2 –extracted RPC resulted in the production of protein-rich and fibre-rich fractions. Dry fractionation of the obtained fractions using the other separation method allowed to recover protein from the fibre-rich fractions, while further protein enrichment from the ...
Dry fractionation of three starch-containing legumes was achieved by combining air classification and electrostatic separation. By fine milling flours consisting …
Electrostatic precipitators usually have efficiencies of greater than 99%. In addition to horizontal versus vertical flow, electrostatic precipitators include wet and dry precipitators. A third, specialized type of electrostatic precipitator is a desalter, which removes salts and sediment from crude oil streams. Equipment Design
Dry separation technology in coal beneficiation has been studied for a long time, and some dry separation techniques have been invented. The air dense medium fluidize bed separation is one potential technique intended to be a substitute for conventional dense medium cyclone/vessel [5], [6], [7]. Although some applications of the …
electrostatic precipitator, a device that uses an electric charge to remove certain impurities—either solid particles or liquid droplets—from air or other gases in smokestacks and other flues. The precipitator functions by applying energy only to the particulate matter being collected, without significantly impeding the flow of gases. Originally designed for …

Comparison between electrostatic separation and dry separation in food industry. Electrostatic filtration is a method of separating particles using an electric field to collect particles of different sizes, shapes, and charge. It is typically used in industrial processes to remove dust and other small particles from the air.

Electrostatic separation is usually applied when dielectric particles are handled. Dielectric particles, when electrostatically charged, can be separated according to their polarity charge (Reinsch et al., 2014). The electrostatic separation architecture is commonly constituted by two electrodes: one positive and the other negative.
