Low Temperature Sea Buckthorn Seed Oil Extraction Machine (Subcritical Extracting)
- Subcritical Fluid Extraction Machine
Subcritical fluid extraction technology is the best choice for extracting natural product including sea buckthorn oil extraction and eucalyptus oil extraction. It has the advantages of low temperature extraction, low cost, short production cycle, high extraction efficiency and safety and reliability. What’s more, it can keep the biological active ingredients of sea buckthorn oil very well. Besides, it has broad application prospect in large scale industrial production.

- 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)
Sea buckthorn seed oil is a kind of precious essential oil of high value (how to make the best essential oil extraction business plan), containing a variety of vitamins and bioactive ingredients. One whole fruit of sea buckthorn only has one seed of sea buckthorn. 1000 seeds of sea buckthorn can produce about 10g seed oil. For 20 tons of sea buckthorn fruits, you can get about 1 ton of seeds. About 20 tons of sea buckthorn seeds are needed for a 1 ton per hour buckthorn oil extraction plant or factory. To get high quality sea buckthorn seed oil, choosing the oil extraction machine is the key step.
