Food raw liquids such as egg liquid, plant juice and fermentation broth inevitably contain fine suspended solids, cell debris and colloidal impurities during production. Traditional static sedimentation and frame filtration suffer from long cycle, low efficiency and secondary pollution risks, which cannot meet continuous industrial production requirements. High-speed disc centrifugal separation technology achieves rapid solid-liquid separation through density difference under fully enclosed conditions. It efficiently removes micro impurities without damaging material activity, improving liquid clarity and reducing subsequent membrane system fouling. This technology has become essential high-efficiency pretreatment equipment for modern food and biological deep-processing lines.
