Advantages of supercritical co2 extraction:

The essential feature of the supercritical carbon dioxide extraction machine is to use environmentally friendly, non-toxic, non-residual CO2 instead of water or organic solvents as the extraction medium, and extract under conditions close to room temperature. Its biggest advantage is to separate the extraction (refining) ) And removal of solvents, etc.

Features of supercritical co2 extraction:

1. Carbon dioxide is cheap, non-flammable, non-explosive, sterilizing, and non-bacterial.

2. Low critical temperature, suitable for the extraction and purification of heat-sensitive compounds.

3. The extraction temperature is low, usually no more than 80°C (mostly around 50°C), which will not destroy the natural activity of the active ingredients.

4. The extraction speed is fast, non-toxic, non-flammable, safe to use, and does not pollute the environment.

5. It can provide an inert environment to avoid product oxidation and does not affect the effective components of the extract.

6. Reasonable structure: SFE equipment is a high-pressure equipment. Therefore, we use short connections, high strength, and light vibration in the design to ensure safety and efficiency, so as to reduce production costs and increase extraction speed.

7. Automatic operation: Extraction kettle cover and quick-opening structure, use the remaining gas of the system to open the cover, double extraction kettles work alternately, changing the kettle time is less than 5 minutes, saving a lot of time than the traditional method, but also reducing labor intensity.

What is the effect of the extraction temperature on the supercritical co2 extraction?

The influence of temperature on the dissolving ability of supercritical fluids is more complicated. Under certain pressure, increasing the temperature will increase the volatility of the extract, which increases the concentration of the extract in the supercritical gas phase, thereby increasing the amount of extraction; but On the other hand, as the temperature increases, the density of the supercritical fluid decreases, so that the solubility decreases, and the extraction volume decreases.

What are the applications of supercritical co2 extraction?

The characteristics of supercritical CO2 extraction determine its wide range of applications. For example, in the pharmaceutical industry, it can be used for the extraction of effective ingredients of Chinese herbal medicines, the refining of heat-sensitive biological products, and the separation of lipid mixtures; in the food industry, the extraction of hops, the extraction of pigments, etc.; in the perfume industry, natural and Refining of synthetic spices; separation of mixtures in the chemical industry, etc.
