Supercritical Carbon Dioxide Extraction Machines

The 600LX3 Supercritical Extraction Device is an efficient chemical separation technology, commonly used to extract active ingredients, pharmaceuticals, spices, and chemical products from natural plants. It utilizes the unique properties of supercritical fluids, adjusting the solvent's physical properties beyond the critical point to achieve higher solubility and diffusivity, enabling efficient separation and purification.

Pure Natural

Supercritical CO₂ fluid extraction is the cleanest extraction method. Since no organic solvents are used, there is absolutely no residual solvent in the extract. This prevents harmful substances from entering the product and eliminates environmental pollution during extraction, ensuring 100% natural purity.

High Efficiency

Extraction and separation are combined into a single step. When the CO₂ fluid saturated with dissolved substances enters the separator, a drop in pressure or change in temperature causes the CO₂ and extract to separate immediately (gas-liquid separation). This method not only improves extraction efficiency but also reduces energy consumption, enhancing productivity and lowering costs.

Safety

CO₂ is an inert gas, meaning no chemical reactions occur during extraction. It is non-flammable, odorless, tasteless, non-toxic, and entirely safe for use.

Low Cost

CO₂ gas is inexpensive, highly pure, and easy to produce. It can also be recycled during production, further reducing operational costs.

1.Selection of Extractant – Choose a suitable solvent based on the target compound's properties.

2.Mixing and Contact – Combine the extractant with raw materials, promoting mixing through heating or stirring.

3.Oscillating Extraction – Shake the mixture to enhance contact and accelerate solute transfer.

4.Standing and Stratification – Allow the mixture to settle and separate into distinct layers.

5.Separation – Isolate the extraction phase from the original solution.

6.Repeated Extraction (if needed) – Perform multiple extractions to improve purity.

7.Concentration and Purification – Further refine the extracted product using methods like evaporation or crystallization.

Biomedicine:

It can be used for extracting active ingredients from Chinese herbal medicines, refining heat-sensitive biological products, and separating lipid mixtures (such as linseed oil and Ganoderma lucidum spore oil in health products). Additionally, it is suitable for extracting essential oils, such as lavender and rose essential oils. It can also be applied to mixture separation, including the removal of harmful substances in citric acid.

Food Industry:

It is used for extracting hops, lycopene, and capsaicin, as well as corn germ oil, wheat germ oil, egg yolk oil, lecithin, spirulina, and carotene. In the spice industry, it is applied to the extraction and refining of natural and synthetic spices, such as pepper oil. It can also extract antioxidant active substances from ginger. Supercritical technology can remove caffeine from tea or coffee beans while preserving their original color, aroma, and taste.

Textile Printing and Dyeing:

Since no water is used in the printing and dyeing process, it eliminates water pollution issues. Additionally, drying is unnecessary after dyeing, shortening the production process. The dyeing speed is fast, dyeing performance is excellent, and color reproducibility is high. This method can also dye certain synthetic fibers that are typically difficult to process, such as polypropylene and aramid.
