Sanitary Horizontal Decanter Centrifuge for Egg Yolk Peptide Raw Material Separation

The global functional food market sees surging demand for egg yolk peptide, a high-value active ingredient widely used in health supplements, sports nutrition and infant auxiliary food. Traditional solid-liquid separation methods such as plate-frame filtration and static sedimentation fail to separate egg residue, protein hydrolysate and impurity sediment efficiently, featuring low peptide recovery, long processing time and frequent filter material replacement. Horizontal decanter centrifuges rely on continuous differential speed centrifugal separation to separate solid egg residues and liquid peptide stock solution in one sealed step under low-temperature mild conditions. This paper illustrates the working principle, structural features, complete technological flow and multi-scenario application value of food-grade horizontal decanter centrifuges in egg yolk peptide processing. Compared with conventional separation equipment, the decanter centrifuge delivers continuous automatic opera

Cross-Flow Reverse Osmosis Membrane System for Dairy Wastewater Resource Recycling

Dairy production generates massive wastewater rich in lactose, protein, fat and organic matter. Direct discharge causes serious environmental pollution and wastes recyclable water resources. Traditional wastewater treatment including sedimentation and biochemical tanks occupies large space, consumes high power and fails to recover reusable water efficiently. Reverse osmosis (RO) cross-flow membrane technology can intercept organic pollutants and salt substances at low temperature, realizing wastewater purification and water recycling simultaneously. This paper introduces the working principle, structural configuration, process flow and practical advantages of industrial RO membrane systems for dairy wastewater treatment. Compared with conventional treatment methods, RO membrane equipment achieves high water recovery rate, small floor area and automatic operation, helping dairy factories cut water procurement cost and meet global environmental discharge standards, delivering dual benefi

Three-Phase Disc Stack Centrifuge: Core Separation Equipment for Continuous Vegetable Oil Refining Lines

Global edible oil manufacturers are pursuing continuous, low-loss, high-clarity refining processes to boost oil yield and extend product shelf life. Traditional separation methods including static sedimentation tanks and frame filter presses suffer from long processing cycles, high oil loss, frequent filter media replacement, and incomplete removal of gums, soapstock and free water, which severely restrict the quality and economic benefits of refined vegetable oil. Three-phase disc stack centrifuges adopt density difference centrifugal separation principle, realizing one-step simultaneous separation of oil, water and solid impurities under sealed continuous operation. This paper elaborates the working mechanism, structural advantages, standard refining process and multi-scenario application value of industrial three-phase disc centrifuges in vegetable oil production. Compared with conventional separation equipment, automated disc centrifuges deliver higher separation efficiency, lower
