Supercritical Extraction Technology

  Comparison between Supercritical Extraction Technology and Anhydrous Extraction Technology, as well as their respective advantages and application areas: Supercritical Extraction Technology: Supercritical extraction is a separation technique that uses a supercritical fluid, usually carbon dioxide, as a solvent. Under high pressure and temperature, carbon dioxide can reach a supercritical state, exhibiting properties between gas and liquid, with high diffusivity and low viscosity. Its main advantages include: Environmentally friendly: Supercritical carbon dioxide is a natural, non-toxic, and harmless solvent that can be easily released by depressurization after the operation, eliminating the need for hazardous organic solvents. Mild conditions: Supercritical extraction is conducted at relatively low temperatures, helping to preserve the activity of volatile and heat-sensitive compounds. Versatility: By adjusting the temperature and pressure, selective extraction of different compounds

  I hope this post finds you well. Today, I would like to shed light on the remarkable applications of supercritical extraction technology in the precision metal casting industry. Specifically, I will highlight how this cutting-edge technology can effectively remove impurities such as oils and grease from intricate metal castings. During the production process of metal castings, lubricants and anti-rust agents are commonly used, which may leave residues on the final casting surface. However, supercritical extraction provides a highly efficient solution to ensure the quality and purity of cast metal components. Supercritical extraction works by utilizing a supercritical fluid, typically carbon dioxide, which is brought into contact with the oils and impurities at high pressure and temperature. In the supercritical state, carbon dioxide exhibits properties of both gas and liquid, enabling it to penetrate into minute pores and narrow channels. By precisely adjusting temperature and pressu

We have been testing on some extractions for our partners. The first one we are preparing for decaffeination of coffee beans. They are a couple of ways to do this extraction. But essentially the method I’ve opted for is to swell the bean in water before the extraction. I have run a few variants for the customer so they can see the potential in using co2 for this process. This is one of about 5 testings we are undertaking  If you want to discuss the project (decaffeination of coffee beans) with us why not get in touch .
