Supercritical Fluid Extraction For Hemp & Herbs

The best parameters for extracting CBD oil using a supercritical co2 extraction machine:

Pulverization degree:20-40 mesh

Moisture content:<8%

Extraction pressure:30Mpa

Extraction temperature:50-60 °C

Extraction time:90-120 minutes

CO2 flow:150~200kg/h

Summary

Supercritical extraction is the most common way of plant extraction. Supercritical materials use the movement of carbon dioxide gas to gradually dissolve liquid and other substances, and finally provide safe and pure CBD products.

When extracting industrial hemp oil rich in cannabidiol, the selected industrial hemp (including leaves, stems and seeds) is first placed in an oven and dried at 50 ° C for 12 hours; then pre-dried The industrial hemp is put into a pulverizer and pulverized into 20-mesh industrial hemp powder. The industrial hemp powder is placed in an oven and dried at 50 ° C for 12 hours; the dried industrial hemp powder remains in the drying oven. The inside is naturally cooled to normal temperature; 132.0 g of cooled industrial hemp powder is weighed into a material bucket of the extraction kettle, and C0 2 gas is injected into the extraction kettle for extraction, the extraction temperature is 60 ° C, the pressure is 30 MPa; the CO 2 gas is extracted by extraction. The flow rate of the kettle is 200kg/h, and the extraction time is 1.5h. The industrial hemp oil rich in cannabisdiol in industrial hemp powder is dissolved in the supercritical CO 2 fluid, and then the industrial hemp oil rich in cannabidiol is used. The C02 fluid was analyzed from the extractor by throttling expansion to the separation vessel to obtain 6.49 g of industrial hemp oil rich in cannabidiol, and the oil yield was 4.92%. Finally, the industrial hemp oil rich in cannabisdiol is dissolved in a homogenizer after heating at 80 °C, homogenized and filled, and stored in the dark.

Description

It is found that there are more than 130 kinds of cannabinoids in hemp (cannabinoids are the effective components extracted from hemp plants), most of which have high application value. THC and CBD are two common cannabinoids. Unlike THC, CBD does not cause hallucinogenic addiction and has an inhibitory effect on this "toxicity". CBD has a high market value. CBD is used in medical treatment, with analgesic, anti-inflammatory, anti epilepsy, anti-cancer, anti anxiety, treatment of depression and other effects; it is used in food, with the effect of improving sleep quality and immunity; it is used in skin care products, with the effect of anti-oxidation, anti-inflammatory and acne elimination.

Supercritical co2 extraction

Supercritical extraction is the most common way of plant extraction. Supercritical materials use the movement of carbon dioxide gas to gradually dissolve liquid and other substances, and finally provide safe and pure CBD products.

Supercritical CO2 extraction technology is the latest subject in modern chemical separation and it is an advanced separation technology rising in the world. The so-called supercritical fluid is the thermodynamic state liquid which is above the critical point and the critical point is the point at which the gas-liquid interface just disappears. The supercritical fluid has a very unique physical and chemical properties, its density close to the liquid, viscosity close to the gas. The big diffusion coefficient, low viscosity, big dielectric constant and other characteristics make its separation effect better, so it is a good solvent. Supercritical extraction, namely, under high pressure and appropriate temperature, solvent contact with the material in the extraction vessel, the solute diffuses into the solvent, and then in the separator change the operating conditions to separate out the dissolved substance in order to achieve separation purposes.

Extraction steps:

1. Prepare carbon dioxide in the compression chamber, reduce the temperature to below - 69 ° F and increase the pressure to above 75 psi. At this time, carbon dioxide gas is converted into liquid.

2. Increase the temperature and pressure until the liquid becomes "supercritical". In fact, supercritical carbon dioxide can fill a container such as a gas while maintaining a density such as a liquid. When carbon dioxide is in supercritical state, it is the best choice for chemical extraction because it will not cause denaturation or damage.

3. Put high-quality hemp in the extractor, and supercritical carbon dioxide dissolves in the extractor and collects plant extracts.

4. Send the liquid carbon dioxide into the low-pressure separator chamber, and the plant extract will be automatically separated from the carbon dioxide.

5. Carbon dioxide is returned to the storage tank to drain CBD oil from the separator.
