Protein hydrolysis and enzymatic digestion processes produce crude polypeptide liquid containing macromolecular impurities, undigested protein, suspended solids and colloidal residues. Traditional purification methods such as alcohol precipitation and vacuum concentration cause serious active peptide loss, low product purity and high energy consumption, failing to meet the production requirements of high-purity functional polypeptide raw materials. Cross-flow ultrafiltration membrane technology realizes precise molecular grading and low-temperature concentration through physical screening. It effectively intercepts invalid macromolecular impurities while retaining small-molecule active polypeptides, improving product purity and solution clarity. This low-temperature, green and efficient membrane process has become the preferred refining solution for modern biological protein deep-processing enterprises.
A large amount of wet herbal residues are produced during the water extraction and alcohol extraction processes of traditional Chinese medicine and plant extracts. The untreated herbal residues feature high moisture content, large stacking volume and perishable characteristics, which easily cause mildew, odor diffusion and secondary environmental pollution. Traditional dewatering methods such as natural drying, belt filter press and plate-frame pressure filtration have many shortcomings including low efficiency, high labor cost, easy blockage and unstable dewatering effect. The horizontal decanter centrifuge realizes continuous automatic solid-liquid separation through high-speed centrifugal sedimentation. It effectively reduces the moisture content of herbal residues, recovers residual extraction liquid, reduces solid waste volume and realizes resource recycling. As stable and environmentally friendly processing equipment, it is widely used in modern herbal medicine deep-processing pr
Dairy raw milk and whey liquid contain complex fat components, suspended solids and protein precipitates. Traditional thermal fat separation and static flotation processes feature low separation accuracy, long processing cycles and unstable fat recovery rates, which cannot meet the standardized production requirements of high-purity cream and defatted dairy raw materials. The horizontal decanter centrifuge adopts high-speed centrifugal sedimentation technology to realize continuous three-phase separation of solid, liquid and fat. It efficiently separates milk fat, residual solid impurities and defatted liquid under low-temperature closed conditions. The equipment improves fat recovery rate, guarantees stable product quality, and reduces raw material waste, becoming essential core equipment for modern dairy raw material refining and cream processing lines.
