Supercritical CO2 extraction peony seed oil production line

Supercritical CO2 Fluid Extraction

Supercritical fluid extraction (SFE) is the earliest technology developed by supercritical fluid. Its basic principle is that in supercritical state, supercritical fluid is in contact with the substance to be extracted, so that it can selectively extract the required active ingredients, and then With the help of decompression and temperature rise, the solubility of the substance to be separated is reduced and precipitated, so as to achieve the purpose of extraction and separation. Supercritical fluid has strong solubility for fat-soluble substances, good mass transfer performance, and is non-toxic, environmentally friendly and safe. , low price and other advantages make it widely used in natural products, especially in the extraction of functional vegetable seed oil.

Features of supercritical CO2 fluid extraction

SFE has the advantages of non-toxic, environmentally friendly, low operating temperature, short extraction time, and pure natural products in plant seed oil extraction. Reflects the incomparable superiority of other methods. However, due to the large one-time investment of equipment, the product cost is relatively high. Therefore, it is necessary to select products with high added value as extraction objects, especially for some products with scarce resources and strong efficacy. At the same time, supercritical extraction technology It can be combined with other advanced technologies, such as rectification, molecular distillation, GC-MS, HPL, C, IR, etc. With the maturity of domestic equipment technology, the investment of supercritical equipment will be greatly reduced. If it is combined with other The combination of unit operation and application will further improve production efficiency and will play a positive role in promoting the modernization of functional oil production.

Supercritical CO2 refined peony seed oil production line

The first set of negative pressure countercurrent supercritical CO2 refined peony seed oil production line produced (supercritical extraction equipment) by our company, was successfully tested and put into use in Changzhou Guosetianxiang peony oil production base. This production line produced more than 2 tons of peony essential oil in more than two months, forming a sales of about 10 million yuan.

     Peony seed oil is rich in linolenic acid, it has a great medical effect on reducing human blood sugar and blood lipids and enhancing immunity, it is called “liquid gold”. Our company cooperates with the Northwest A&F University and other related scientific research institutions, we finally developed a successful set of screening, shelling, sorting, drying, oil in one of the Peony seed production line after two years of efforts.

     Company plans in addition to peony seed oil production line sales, at the same time to do deep processing, we will develop the company into a comprehensive base of peony seed oil, which integrates production, processing and sales.
