In modern industrial production, separation technology runs through multiple links, especially in the food, biopharmaceuticals, fine chemicals, environmental protection treatment and other industries, which put forward higher requirements for the efficient and accurate separation of liquid-liquid-solid three-phase or liquid-solid two-phase mixtures. Traditional sedimentation methods or ordinary centrifugal equipment often have shortcomings in separation accuracy, processing efficiency and space occupation.As a special equipment with high speed and high separation factor, the tubular centrifuge has become the “hidden champion” in the field of fine separation with its unique structural design and excellent separation effect. Especially when dealing with trace suspended particles, emulsions, oily waste liquids, cell culture fluids and other materials, it has incomparable advantages.
What is a tubular centrifuge?
A tubular centrifuge is a high-speed device suitable for separating low-concentration, fine particles or liquid-liquid separation. It mainly generates ultra-strong centrifugal force through high-speed rotation, quickly separates different components in the material, and achieves high-precision separation effect.
1. Core structure composition
Drum (cylinder): a slender cylindrical container, which is the core of the entire separation process, with a diameter of usually 60-150mm and a length of 800-1200mm.
Drive system: adopts motor direct drive or belt drive system to achieve a speed range of 15000-25000 rpm.
Body shell: adopts stainless steel closed structure to ensure safety, cleanliness and pollution-free.
Liquid collection tray and liquid outlet: used to export clear liquid, can be divided into single outlet and double outlet design to meet the needs of liquid-liquid separation.
2. Separation principle
The material enters from the bottom of the drum. Under the action of high-speed centrifugal force, the solid phase with high density is thrown to the inner wall of the drum, and the liquid with low density is close to the center to form a clear liquid layer. For a liquid-liquid-solid three-phase mixture, the light phase liquid, heavy phase liquid and solid are layered in turn, thus achieving three-phase separation.
Core advantages of tubular centrifuge
1. Ultra-high speed, super separation ability
The speed is up to 25000rpm, the centrifugal force can reach 20000×g, and it can effectively separate particles of 0.1μm level. The separation accuracy is much higher than that of ordinary horizontal screw and disc centrifuges.
2. Three-phase separation, one machine for multiple uses
The tubular centrifuge can achieve liquid-liquid-solid three-phase separation, which is suitable for complex systems such as emulsions, oil-water mixtures, and biological fermentation liquids. It is an ideal choice that cannot be replaced by similar equipment.
3. High clarity of clear liquid and stable liquid output
The equipment is designed with a special liquid collection tray and anti-fluctuation structure to ensure uniform liquid flow rate, small fluctuation, high clarity, and greatly improve product quality.
4. No filter cloth is required, no risk of clogging
No filter material separation throughout the process, suitable for high-viscosity, oil-containing or easily blocked materials, maintenance-free, easy to clean, and corrosion-resistant.
5. Small footprint and flexible installation
Compact structure and easy operation, suitable for laboratories, pilot lines, small-scale production lines or front-end pretreatment modules of large equipment.
Applicable industries and application scenarios
1. Biopharmaceuticals and vaccine production
Tubular centrifuges are widely used in cell collection, bacterial concentration, fermentation broth separation, bioactive substance extraction, vaccine purification, recombinant protein recovery and other links, and are common configurations of GMP-certified factories.
2. Plant extraction and Chinese medicine concentration
In Chinese medicine extraction and natural product separation, it can efficiently separate solid residues and effective ingredients in turbid liquids, achieve high clarity and low residual rate, and is conducive to extract refining.
3. Food and beverage industry
