Principle of centrifugal extractor:


Centrifugal extractor is a multi-functional equipment that realizes liquid-liquid two-phase extraction, separation, mixed mass transfer, reaction and washing by centrifugal force. Two-phase liquids with differential gravity (non-blending) are separated/extracted by centrifugal force. The non-fused two-phase liquid enters the centrifugal extractor respectively, and is fully mixed by rotating the rotor and mixing impeller to promote the transfer of solute. After mixing, it is sucked into the rotor to gradually separate/extract. The mediated liquid phase is collected into the two collecting volumes of the light phase and the heavy phase respectively and discharged by another outlet. Materials of different densities and viscosities can be met by changing weir plates and rotating speeds.

A solution of one or more solutes (shown in blue) when a centrifugal extractor performs liquid-liquid separation/extraction. With a density difference, a non-fused solution (shown in yellow) enters the device mixing chamber. Rotate the drum and mixing impeller for material mixing (green). The mixture is sucked into the drum for phase separation, the centrifugal force of the drum and the gravity of the material disperse the heavy phase (blue) to the outside of the drum, and the heavy phase liquid overflows from the adjustable heavy phase weir plate to the heavy phase collection chamber and is discharged. The light phase liquid (yellow) spills from the light phase weir plate to the light phase collection chamber inside the drum.

Multistage countercurrent extraction (illustrated)


Multistage countercurrent to achieve a variety of materials extraction process, extraction purity, clarification and so on. The process is simple, no pump is required between extraction, and the number of stages is flexibly increased to achieve better production process requirements. According to the process requirements, such as: reaction, washing, stripping and other processes are directly added or discharged in the process pipe.


Equipment design features (advantages):


1. Vertical direct motor drive, simple structure, simple maintenance, small footprint


2. High speed, rapid phase separation, separation density difference is greater than or equal to 0.015


3. No foundation installation, arbitrarily placed on the relative horizontal ground, floor, platform can be


4. Convenient for single-stage or multistage series countercurrent or cross-flow washing, reaction and extraction separation


5. Strong adaptability, by changing the weir plate and speed can be filled with different density, different viscosity of the liquid liquid


6. The machine content is small, saving extractants, solvents or detergents


7. Fully closed operation, no leakage, conducive to explosion-proof, toxic, harmful, volatile and other materials


8. Debugging is simple and fast, when changing the process and materials, it can quickly adjust the weir plate or speed change the centrifugal force to switch the phase separation interface


9. There is no need to set the pump in the middle of the multi-stage series, and the extraction stage can be arbitrarily increased to achieve the best extraction effect


10. Smooth operation, high degree of automation, unmonitored continuous operation or intermittent operation and other advantages


11. A variety of mixed design, according to the nature of the material selection, improve the mass transfer efficiency, can be applied to shear sensitive emulsion materials


12.GMP requirements can be optional in-place cleaning, suitable for intermittent use or replacement of material cross contamination


13. Large length-diameter ratio, high speed, thorough phase separation


14. No mechanical seal, no leakage to reduce maintenance costs


15. Low energy consumption, according to different media and flow options


Widely used: food, pharmaceutical, agrochemical, metallurgy, industrial wastewater, biopharmaceutical, biological engineering, plant extraction, fine chemical, petrochemical, environmental protection chemical...... And other industries.
