  • Screw Pressing Machine: It is a traditional seed oil extraction process. However, in the process of pressing, due to the increase of pressure and internal friction, the temperature will rise which can destroy the active ingredient. So to get high quality oil products, cold pressing is required. But the oil yield of this extraction process is low.
  • Traditional Solvent Extraction Machine: Organic solvent extraction method has high oil yield but it has the problem of solvent residue.
  • Supercritical CO2 extraction machine: This extraction technology has large investment, and it cannot be used in large production due to the limitations of the equipment itself, and the production cost is extremely high. (here listed the detailed comparison of Subcritical extracton and supercritical extraction)
