Supercritical CO2 Extraction Machine 2100L(700Lx3) Model

it is high-capacity industrial system designed for efficient, solvent-free extraction of essential oils, active compounds, and bioactives from plant materials. It features three extraction vessels of 700 liters each, allowing for flexible operation in parallel or series to increase throughput and reduce downtime during loading and unloading. Operating at pressures up to 350 bar, the system uses supercritical carbon dioxide as a clean, non-toxic solvent to selectively extract target compounds without thermal degradation. It includes multiple separation vessels for precise compound collection, along with advanced automation for temperature, pressure, and flow control. With a co-solvent system and CO₂ recycling unit, the setup ensures high efficiency, minimal waste, and optimal purity of extracts. Built using food-grade stainless steel and equipped with modern safety features, this machine is ideal for large-scale operations in industries such as pharmaceuticals, food processing, cosmetics, and herbal extraction.
