What is a tubular centrifuge?
Tubular centrifuge is a high-speed centrifugal separation equipment, which is widely used to process materials with fine solid particles, low solid content but extremely high separation requirements. Its core structure is a slender stainless steel drum, usually with a diameter of 45mm150mm and a length of about 400mm1000mm. When working, the drum rotates at ultra-high speed (up to 20,000rpm or more), and the different components in the mixed liquid are quickly separated under the action of a strong centrifugal field.
Working principle:
Liquid-solid separation: When the suspension rotates at high speed, the solid particles are thrown to the inner wall of the drum due to their high specific gravity, while the clarified liquid is located in the central axis area and discharged through the top overflow port;
Liquid-liquid separation: Two liquids with different densities but immiscible with each other form concentric annular layers under a high-speed centrifugal field and flow out from different outlets respectively;
Liquid-liquid-solid three-phase separation: Solids are deposited, and the light phase and heavy phase liquids are discharged along different paths respectively.
Because its separation accuracy can reach sub-micron level, the treated clarified liquid has high cleanliness and extremely low residual impurities, it is widely used in industries that pursue high purity, high yield and high repeatability.
Six core advantages of tubular centrifuges
1. Ultra-high-speed separation, leading precision
Our tubular centrifuges are made of high-strength aviation-grade stainless steel with dynamic balancing treatment, which can achieve a speed of up to 18,000~22,000RPM and a centrifugal force of more than 16,000×g, greatly improving the separation efficiency and clarity, and are particularly suitable for processing fine particles and low-concentration suspensions.
2. High-purity output, thorough impurity removal
Because its centrifugal force is much higher than other centrifugal equipment (such as horizontal screw and disc type), even impurity particles of 0.1 micron level can be effectively settled, ensuring that the clarity of the liquid meets the requirements of experimental and pharmaceutical grades.
3. Compact structure, space saving
The whole machine has a vertical structure and a small footprint, which is suitable for laboratories, pilot lines and industrial production lines; plug-and-play, easy to integrate into sterile workshops or clean plants.
4. Various materials to meet the needs of multiple industries
The equipment can use special metal materials such as 316L, 2205, 904L, titanium alloy, Hastelloy, etc., which can adapt to high-acid, high-alkali, high-salt, high-viscosity, and high-corrosive material environments.
5. Continuous operation can be achieved
Some models support continuous feeding and discharging, greatly improving processing efficiency and meeting the needs of large-scale industrial production.
In-depth analysis of application fields
1. Biopharmaceutical field
In vaccine production, plasma separation, bacterial recovery, enzyme preparation purification and other links, tubular centrifuges can achieve efficient extraction and separation of cell residues, virus particles, microbial extracellular proteins, etc., effectively keeping the active ingredients intact.
2. Chinese medicine and plant extraction
In the treatment of Chinese herbal medicines and plant raw material extracts such as astragalus, salvia miltiorrhiza, ginseng, ganoderma lucidum, blueberry, grape seeds, etc., tubular centrifuges can be used to remove fiber impurities, silt, and residues, and improve the subsequent concentration and extraction efficiency.
3. Food and beverage industry
Used for milk fat separation, tea polyphenol purification, protein separation, juice clarification, etc., to ensure that the flavor is not damaged and the color is pure.
4. Chemical fine separation
Applicable to emulsion demulsification, resin colloid separation, nanomaterial sedimentation, oil-water separation, etc., with obvious advantages in scenes with high precision requirements.
5. Environmental protection and waste liquid treatment
In wastewater pretreatment, emulsified oil recovery, and biochemical reaction liquid purification, tubular centrifuges can be used as terminal purification equipment to improve the emission compliance rate.
In the era of precise separation, tubular centrifuges are not only equipment, but also the core engine driving quality evolution, efficiency improvement, and industrial upgrading.
