The 50L–500L supercritical CO2 extraction system is designed for efficient and solvent-free extraction of botanical materials such as , herbs, and aromatic plants. By using carbon dioxide under controlled temperature and pressure, the system converts CO2 into a supercritical fluid that combines the penetration ability of gas and the dissolving power of liquid. This enables precise extraction of cannabinoids, terpenes, and essential oils while preserving their natural properties. Compared with traditional solvent extraction, this system ensures higher purity, no toxic residue, and better product consistency. Its closed-loop design allows CO2 to be recycled, reducing operational costs and making it an environmentally friendly solution for modern extraction businesses.

Many extraction manufacturers face challenges such as inconsistent product quality, solvent contamination, and high operational risks. Traditional extraction methods using ethanol or hydrocarbons often require additional purification steps, increasing production time and cost. In addition to this, these solvents can damage delicate compounds like terpenes and pose safety risks due to their flammability. As regulations in food, pharmaceutical, and cosmetic industries become stricter, these limitations make traditional extraction methods less competitive.

The supercritical CO2 extraction system provides a clean, efficient, and highly controllable solution. Operators can adjust pressure and temperature to selectively extract desired compounds while preserving sensitive ingredients. The integrated separation system allows for fractionation, enabling different components to be collected in stages during a single extraction cycle. With a CO2 recovery rate above 95%, the system minimizes waste and significantly reduces operating costs. Automation through PLC control ensures stable performance, reduces labor requirements, and improves overall production efficiency.

This CO2 extraction system is widely used in CBD oil extraction, essential oil production, herbal medicine processing, and food-grade ingredient manufacturing. It is also suitable for cosmetics and fragrance industries where high purity and natural extraction are required. Businesses targeting premium markets benefit from the consistent quality and solvent-free process provided by this system.

The process starts by loading dried plant material into the extraction vessel. CO2 is then compressed and heated until it reaches a supercritical state. In this form, CO2 acts as a solvent, dissolving target compounds from the biomass. The CO2 carrying the extracted compounds flows into separation vessels where pressure is reduced. As pressure drops, the compounds separate and are collected as oil. The CO2 is then cooled, condensed, and recycled back into the system, forming a continuous closed-loop cycle that maximizes efficiency and minimizes waste.

When selecting a supercritical CO2 extraction system, consider your production scale and business goals. For small to medium operations, 50L to 100L systems are suitable, while 300L to 500L systems are ideal for industrial production. If your focus is on high-value products such as terpene-rich extracts, a multi-stage separator system is recommended. Automation level is another key factor, as fully automated systems reduce labor costs and improve consistency. Additionally, consider material standards and certifications if you are targeting food or pharmaceutical markets.
