The booming global market of high-protein baking materials, sports nutrition supplements and clean-label food ingredients fuels surging demand for high-activity concentrated egg white protein. The complete egg liquid processing chain relies on two core separation equipment: sanitary horizontal decanter centrifuge for continuous solid-liquid impurity removal, and cross-flow ultrafiltration membrane system for low-temperature protein concentration. Traditional single-process equipment cannot integrate residue separation and gentle concentration, leading to low protein recovery, serious thermal denaturation and high energy consumption. This article systematically introduces the matching working principle, sanitary structural design, full production flow and industrial comprehensive advantages of decanter centrifuge paired with UF membrane system in egg deep processing. The combined separation line realizes full-automatic continuous production, retains complete foaming, emulsifying and gel
