50L×4 supercritical CO2 extraction system is a medium-scale industrial solution designed for efficient and clean extraction of plant-based active compounds. Equipped with four 50-liter extraction vessels and three 20-liter separation vessels, it supports flexible operations such as alternating or parallel extraction. This setup is ideal for extracting high-value materials like essential oils, herbal actives, CBD from hemp, functional food ingredients, and natural fragrances.

1. System Components and Technical Features

Main Components:

• Extraction Vessels: Four 50L high-pressure chambers for continuous or batch operation.

3. Real-World Applications

Example 1: Rose Essential Oil Extraction

At 30 MPa and 40°C, dried rose petals were processed using the 4-vessel system. Within 90 minutes, highly aromatic oil with over 98% purity was collected—retaining volatile and heat-sensitive compounds. The extract is suitable for perfumes, aromatherapy, and skincare products.

Example 2: Icariin Flavonoids from Epimedium

Using alternating multi-vessel operation, the system extracted flavonoids from Epimedium powder. The gradient separation system collected different polar fractions separately, improving the yield and concentration of the active compounds. It supports formulation R&D for herbal pharmaceuticals.

Example 3: CBD Extraction from Industrial Hemp

At 30 MPa and 40°C, the 50L×4 system continuously processed hemp flowers and leaves. Three separation vessels collected waxes, terpenes, and CBD-rich oil based on boiling point differences. The final product meets export-grade quality standards with no solvent residues.
