Supercritical CO2 fluid extraction of amber essential oil


Amber is a resin fossil formed by tertiary ancient coniferous plants from 30 million to 60 million years ago, which was covered by the earth’s crust and buried deep underground, and formed through formation pressure and thermal metamorphism.


Traditional Chinese medicine believes that amber can be used as medicine.

Experts conducted a test analysis on the curative components of amber, and believed that the curative components in amber were mainly succinic acid, rosinic acid, pine resin and essential oils.

CO2 extraction amber oil

Because the curative components in amber are highly viscous and easy to agglomerate, they adhere to the CO2 fluid supercritical device, which easily causes the equipment pipeline to be blocked and difficult to clean.

At the same time, it is difficult to control the content of the extract and the amount of impurities, so it is used in the amber raw material Add blunt substances to crush and extract together to prevent the curative components in amber from agglomerating, improve the quality of the product, reduce equipment maintenance and reduce production costs.

CO2 supercritical extraction, the use of pressure and temperature to set the gradient change, gradient extraction, the method of collecting the curative components of amber in sections, the condition setting is simple and accurate.

You can read a lot of articles about cbd oil extraction from the Internet, but I can tell you for sure that they are not comprehensive at all, and even have wrong descriptions.

Let’s start reading

CO2 extraction process

Supercritical CO2 extraction process is carried out at close to room temperature, so that the high boiling point, low volatility, and easily pyrolyzed substances are extracted at a temperature far below its boiling point, which effectively prevents the succinic acid, rosinic acid, pine resin and essential oil Oxidation and dissipation, so that the effective ingredients in amber can be better maintained in the extract, and the amber products obtained are of higher quality;

CO2 supercritical extraction is the cleanest extraction method. The extract does not contain nitrates and harmful heavy metals. The whole process does not use organic solvents.

Therefore, there are no residual solvents in the extract. The product is healthy and the process is environmentally friendly, ensuring 100% Pure naturalness; CO2 supercritical extraction combines extraction and separation.

When the CO2 fluid saturated with dissolved matter enters the separator, the purpose of extraction is achieved by changing the temperature and pressure. The pressure is fixed and the temperature can also be changed.

Separate, on the contrary, the temperature is fixed, and the extract is separated by reducing the pressure, so the process is simple and easy to master, and the extraction speed is fast, the energy consumption is less, the production efficiency is improved and the cost is reduced;

CO2 is an inactive gas. There is no chemical reaction during the extraction process. It is a non-flammable gas. It is tasteless, odorless, non-toxic, and has very good safety. The CO2 gas is cheap, high in purity, easy to prepare, and in It can be reused in production, thus effectively reducing costs.


CO2 Extraction Machine Buyer’s Guide

As you can imagine, not all supercritical CO2 extractors are made the same.
For more than 30 years, we have customized many CO2 extraction machines (Tabletop CO2 Extractor) for many companies and university laboratories (1 lb CO2 extractor). Because each customer’s CO2 extraction process requirements are different, there are almost no identical machines.

How many liters of CO2 extraction vessels are needed?

The first factor that determines the size of the CO2 extraction vessel is the daily working hours of the plant, which determines the daily extraction batch. The vessel size of the CO2 extractor depends on the biomass to be processed per day.

How many pressure is best for your CO2 extraction process requirements?

The choice of CO2 extraction pressure is a changing factor. If the extraction pressure is too high, the useless substances in the plant will be extracted, such as wax and chlorophyll. If the extraction pressure is too low, the extraction time will be increased.
