Supercritical CO2 extraction is a cutting-edge technology that has revolutionized the process of extracting essential oils, flavors, fragrances, and bioactive compounds from various raw materials. At the heart of this technology lies the supercritical CO2 extraction machine, a sophisticated piece of equipment that operates through a series of intricately interconnected functional parts.
Supercritical CO2 extraction is a process used to obtain high-quality extracts from a wide range of natural materials, such as herbs, botanicals, and spices. It is favored for its ability to produce pure, clean extracts without the use of toxic solvents.
Top 3 Key features include of Supercritical CO2 extraction process
- Non-Toxic Solvent : Supercritical CO2 (carbon dioxide in a supercritical state) serves as the solvent, eliminating the need for harmful chemicals.
- Selective Extraction : The process allows for the selective extraction of target compounds, leaving unwanted components behind.
- Minimal Residue : Supercritical CO2 extraction leaves little to no residue in the final product, ensuring purity.
Functional Components of a Supercritical CO2 Extraction Machine
A supercritical CO2 extraction machine comprises eight vital functional parts that work in harmony to produce high-quality extracts:
- Extraction Agent Supply System : This system stores and delivers the supercritical CO2 to the extraction vessel. It maintains the pressure and temperature required for the supercritical state.
- Low Temperature System : The low-temperature system ensures that the CO2 is maintained at a temperature below its critical point, allowing it to transition into a supercritical state.
- High Pressure System : This component pressurizes the CO2 to reach its supercritical state. It plays a crucial role in the extraction process by maintaining the necessary pressure.
- Extraction System: This component is responsible for ensuring that the supercritical CO2 efficiently comes into contact with the raw material. It may involve various mechanisms such as co-solvents, static mixers, or other means of achieving thorough mixing.
- Separation System : The separation system is tasked with separating the supercritical CO2 from the extracted compounds and the raw material. It may employ methods like phase separation or pressure reduction to achieve this.
- Modifier Supply System : In some cases, modifiers are introduced to enhance the extraction process. This system delivers these modifiers as needed to optimize extraction.
- Circulation System : The circulation system ensures a continuous and efficient flow of supercritical CO2 throughout the extraction process.
- Computer Control System : The entire process is monitored and regulated by a computer control system, which oversees parameters like temperature, pressure, and flow rates, ensuring precise control over the extraction process.
