Solving Key Challenges in Botanical Extraction
What is Supercritical CO2 Extraction Machine?
Supercritical CO2 extraction processes botanical materials by utilizing carbon dioxide above its critical temperature (31.1°C) and pressure (7.38MPa). In this state, the fluid possesses the high penetrability of a gas and the superior dissolving power of a liquid, allowing it to rapidly penetrate target biomass and dissolve specialized oils and active ingredients. As the solute-laden fluid undergoes fractional reduction in pressure and temperature within the separators, the CO2 instantly vaporizes, achieving a pristine, solvent-free separation without damaging the delicate extracts.
Bit provides high-efficiency supercritical CO2 extraction systems, specifically engineered as a turnkey solution for the precision extracting, fractionating, and purifying of botanical oils, essential oils, and natural pharmaceutical ingredients.

High-Pressure Engineering & System Rigidity
How Is It Built?
Supercritical CO2 extraction systems require a high-rigidity pressure structure and a precision-controlled fluid actuation system to ensure stable mass transmission and accurate extraction performance. Supercritical extraction systems are typically constructed with a reinforced machine frame, synchronized multi-vessel pressure units, and precision clamping/sealing mechanisms. The structure must withstand intense axial fluid pressures (up to 35 MPa – 100 MPa) while maintaining absolute alignment and sealing integrity between the extractor vessels, separators, and high-pressure piping.
Bit CO2 extraction machines are built using advanced PLC-controlled hydraulic, servo, and pneumatic systems, combined with high-strength structural components to ensure consistent process accuracy and long-term stability.
We utilize precision-engineered components and established manufacturing processes to achieve the following characteristics:
High structural rigidity under heavy pressure loads (fully compliant with international standards such as ASME, CE, or PED pressure equipment directives).

How does it work?
Supercritical CO2 extraction operates by applying controlled temperature and pressure to the fluid while it is simultaneously circulated through a biomass bed, allowing the carbon dioxide to enter a stable supercritical state before dissolving target components.
The liquid CO2 is pumped from the storage tank and pressurized to a defined pressure level, typically approaching or exceeding the fluid’s critical point (31.1°C and 7.38mpa). While maintaining this critical parameter, the flow system—such as high-pressure plunger pumps, heat exchangers, and automated valves—guides the fluid through the extraction vessel to achieve the required solubility matrix.
During the supercritical extraction process, multi-channel coordinated loops ensure accurate control of flow rate, pressure, and temperature. This reduces density variations and minimizes parameter fluctuation after fluid loading.
In advanced systems, additional multi-vessel configurations enable cross-pressure manipulation, continuous flow redirection, and multi-stage gradient separation, allowing precise control of complex botanical yields and fractionated volatile profiles.
Through this process, the fluid exhibits optimized mass transfer rates and improved geometric stability, resulting in high-precision pure extracts with consistent batch quality.
