As an important part of traditional Chinese medicine, the optimization and upgrading of Chinese herbal medicine extraction process is crucial to ensure efficacy, improve production efficiency and quality control. With the rapid development of modern pharmaceutical technology, centrifugal separation technology has become an important link in the Chinese herbal medicine extraction industry to achieve efficient separation, purification and concentration. Among them, tubular centrifuges have gradually become the industry’s preferred equipment due to their high speed, high efficiency and precise separation performance.
Tubular centrifuge technology overview
Working principle of tubular centrifuge
Tubular centrifuge is a device that generates a centrifugal field through high-speed rotation to separate different components in a suspension according to density differences. Its core part is a high-speed rotating drum. The liquid is in a thin film state in the drum. Under the action of strong centrifugal force, the components with higher density are thrown to the drum wall, and the lighter components stay in the center area to achieve continuous separation.
Structural features of tubular centrifuge
High-speed drum: usually the speed can reach more than 15000rpm, and the centrifugal force is as high as 15000g, which is suitable for efficient separation of tiny particles and emulsions.
Small inner diameter design: ensure that the liquid flows evenly in the drum and the separation interface is clear.
Continuous feeding and discharging system: realize automatic continuous operation and improve production efficiency.
Good sealing design: prevent liquid leakage and contamination, in line with the clean production requirements of the pharmaceutical industry.
Separation requirements in the Chinese herbal medicine extraction industry
Introduction to Chinese herbal medicine extraction process
Chinese herbal medicine extraction usually involves extracting active ingredients from plant raw materials, such as polysaccharides, flavonoids, alkaloids, etc. The process includes steps such as extraction, filtration, concentration and purification. The extract usually contains a large amount of suspended solids, oils and impurities, and efficient separation equipment is required for solid-liquid separation and liquid-liquid separation to ensure the purity of the extract and the content of active ingredients.
Separation challenges faced by Chinese herbal medicine extraction
Complex liquid phase composition: multiple components are mixed, the density difference is small, and it is easy to emulsify.
High viscosity liquid: some extracts have high viscosity, which makes centrifugal separation difficult.
Various suspended solid particles: different particle sizes and shapes, easy to clog equipment.
High hygiene and safety requirements: Pharmaceutical production has extremely strict requirements on equipment materials and cleanliness.
The key role of tubular centrifuge in Chinese herbal medicine extraction
Efficient separation to ensure product purity
The high-speed rotation of the tubular centrifuge can generate strong centrifugal force, which can quickly settle and separate the solid impurities in the extract, significantly improving the clarity of the liquid. For multi-component mixtures, it can effectively distinguish liquid phases of different densities to ensure that the effective ingredients are not lost.
Continuous automatic operation to improve production efficiency
Compared with traditional filtration equipment, the tubular centrifuge adopts continuous feeding and automatic slag discharge design to reduce manual intervention and ensure stable operation of the production line. It has a high degree of automation and is suitable for large-scale production of medium and large pharmaceutical companies.
Adapt to the separation needs of high viscosity and complex materials
The tubular centrifuge has an optimized structure, uses wear-resistant materials and precision processing, can adapt to the higher viscosity and complex solid forms in Chinese herbal medicine extracts, achieve stable separation, and avoid equipment blockage.
The tubular centrifuge plays an irreplaceable and key role in the Chinese herbal medicine extraction industry with its high efficiency, continuity, intelligence and hygiene. Through reasonable selection and scientific use, the tubular centrifuge not only improves the quality and efficiency of Chinese herbal medicine extraction, but also promotes the transformation of the traditional Chinese medicine industry towards modernization and intelligence.
