This article compares experimental basket centrifuges and conventional rotor-type laboratory centrifuges in principle, separation performance and application scenarios. The basket centrifuge adopts filter separation, which can directly trap solids inside the perforated basket and obtain filter cake with low moisture. In contrast, rotor laboratory centrifuges only realize solid sedimentation in centrifuge tubes, and the sediment still retains high water content. Experimental basket centrifuges are more suitable for lab trials of plant extraction, protein and beverage clarification requiring solid recovery, while rotor centrifuges fit small-volume simple sediment tests. The comparison helps researchers and purchasers select the right lab solid-liquid separation equipment according to their target products.
Industrial starch production generates crude starch slurry mixed with residual protein, fine fiber fragments, suspended solids and soluble impurities during grinding and washing processes. Traditional separation methods such as gravity sedimentation and flat screen filtration feature low separation precision, long cycle time and high residual protein content, resulting in low starch purity and poor product whiteness. The horizontal decanter centrifuge utilizes high-density difference centrifugal separation to realize continuous removal of protein, fine slag and impurities from starch slurry under fully enclosed conditions. It effectively separates starch granules from miscellaneous proteins and fiber residues, improving starch purity, whiteness and extraction yield. As the core purification equipment for starch processing, it is widely applied in corn, potato, tapioca and wheat starch industrial production lines.
Crude animal oil and fish oil extracted from raw animal tissues and fish leftovers contain a large amount of solid impurities, protein residues, suspended particles and emulsified colloids. Traditional purification methods such as heating sedimentation and frame filtration have low separation accuracy, incomplete slag removal and high impurity residue rate, which easily cause oil turbidity, dark color and poor oxidation stability. The horizontal decanter centrifuge adopts high-speed density difference separation technology to realize continuous solid-liquid separation and crude oil purification under low-temperature and fully enclosed conditions. It efficiently removes solid slag, denatured protein and suspended impurities, effectively improving oil clarity and purity. This physical separation process avoids thermal deterioration of oil quality and has become the core pretreatment equipment for modern fish oil and animal fat deep processing.
