CO2 supercritical extraction system

Supercritical fluid extraction(SFE) is an application of advanced green separation technology. Adopting CO₂ as the solvent, supercritical CO₂ fluid has great density and dielectric coefficient and good performance of solubility which can change dramatically with the changes of pressure and temperature. Therefore, the characteristic of selective solubility for different substances can be used for extraction purposes, which also makes the separation of solvent and extract easily.

Compared with conventional separation methods, supercritical CO₂ extraction has its advantages such as low extraction temperature, strong selectivity, high efficiency, low energy consumption, no pollution etc. It’s perfect for extracts that are fat-soluble, have a high boiling point or heat-sensitive and also convenient for fine separation of compound with different components. The supercritical CO₂ extraction technology is widely used in pharmaceutical, chemical and food industries.

With decades of research and production experience on supercritical CO₂ extraction technology and machines, our company proudly offer advanced and mature supercritical CO₂ extraction system and machines with different production capacities to be suitable for different scales of productions. Our systems and devices are well-designed, reliable and of reasonable structures which we incorporate double safety protection system to ensure safety and smooth operation. Our optimized seal structure and material and sealing system are more durable and reliable. The CO₂ is designed to be recyclable and reusable. Digital display on production parameters such as temperature, pressure and flow etc to make the operation and control easily. Entire extraction system can be designed to be computer remote control and meeting GMP standards.

Characteristics of the Supercritical CO₂ Extraction Device:

   •Low supercritical temperature make it suitable for extraction and purification of heat sensitive compound. 

   •Provide inert gas environment to avoid oxidation of products and maintain effective content of extracts. 

   •Fast extraction speed, non- toxic and non-flammable process, safe production and no pollution to environment. 

   •No residue of solvent. No nitrate and heavy metal ions. 

   •CO₂ is recycled and reused in production. 

   •Designed and manufactured per GMP standard.  

   •Can be equipped with computerized automatic control system(temperature, pressure, flow). 

Our mid-large 50L-3000L capacity machines have been successfully used and operated in many domestic and foreign pharmaceutical and bio-tech companies and creating incredible values for our customers. 

As always, customization is available with us and we can design small-pilot or pilot-large scale combination system to suit your needs.
