Application of Horizontal Decanter Centrifuge in Herbal Residue Dewatering

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
