Centrifugal extraction equipment

Centrifugal extraction equipment is designed to process plant materials for the purpose of isolating and concentrating specific compounds, such as active pharmaceutical ingredients, essential oils, and other valuable constituents. This type of equipment is widely used in the pharmaceutical, nutraceutical, cosmetic, and food industries, among others.

Efficient mass transfer​

Adjust the mixing intensity to achieve mass transfer efficiency that greatly exceeds conventional systems. A single extraction stage delivers over 90% efficiency.

Fast phase separation

Phase separation is driven by centrifugal force and completes in seconds. This avoids the slow settling and emulsion formation common in traditional separation.

Sealed and explosion-proof

A flat-plate structure with mechanical seals ensures completely enclosed operation. Ideal for handling flammable, explosive, or toxic solvents, with an optional explosion-proof motor.

Low solvent retention

Minimal liquid retention inside the machine cuts solvent usage and reduces startup, shutdown, and cleaning time.

The centrifugal extraction system is an advanced solution for liquid-liquid separation, integrating mixing, mass transfer, and high-speed centrifugal action into a single, streamlined unit. With its specialized plate-type construction, the equipment generates a powerful centrifugal force field that drives rapid and efficient separation and solute exchange between two immiscible liquid phases-for example, between oil and water, or organic and aqueous media.
 

In contrast to conventional extraction towers or mixer-settler systems, this centrifugal extractor provides clear benefits, including a significantly smaller footprint, enhanced mass transfer performance, and reduced solvent retention. These features make it especially suitable for continuous, high-efficiency operations in demanding sectors such as fine chemical synthesis, pharmaceutical manufacturing, and environmental treatment applications.

This centrifugal extraction equipment finds its primary application in the pharmaceutical and bioengineering industries, where high-value compounds are extracted efficiently and continuously. It is particularly suitable for processing materials that are challenging to handle with conventional methods-such as those with minimal density differences (≥0.05 g/cm³), those prone to emulsification, or those containing trace solids. The equipment excels in extracting temperature-sensitive and easily emulsified substances, including key antibiotics and natural bioactive compounds.
 

Typical applications in this sector include:

1.Antibiotic Recovery: It is used to extract antibiotics like penicillin, erythromycin, and cephalosporins from fermentation broths via solvent extraction. The strong centrifugal force effectively breaks emulsions, helping preserve the integrity and activity of sensitive compounds.

2.Natural Product and Herbal Extraction: The system enables efficient purification of plant essential oils, alkaloids (e.g., camptothecin), and flavonoids. Compared to traditional batch extraction methods, it offers significantly higher yield and consistency.

3.Active Pharmaceutical Ingredient (API) Purification: During the final stages of drug manufacturing, the equipment helps remove trace impurities from reaction mixtures, supporting the production of high-purity active pharmaceutical ingredients.
