L-06 Small CO2 Extraction Machine
Classic Small CO2 Extraction Machine Recommended: 6000mL small CO2 extraction machine is a multi-purpose small-batch CO2 extractor, which has two extractors with different capacities (1000mL+5000mL).
It means that it can work in the extraction capacity of 1L or 5L (5L CO2 extraction vessel can hold 1 pound to 3 pounds of dry biomass material per batch.), which is very important for the work of the laboratory because you can use it to carry out small experiments under the capacity of 1L, and then enlarge the test results to 5L capacity for testing, Prove that the extraction data is reliable, and prepare for large-scale commercial or industrial production.
At the same time, we have equipped it with high pressure of 500 bar. Of course, you can also order a higher gas pressure of 1050 bar to meet a wider range of plant extraction requirements.
Why do you need an L-06?
Supercritical fluid experiments are sometimes limited by the number of raw materials to be extracted, and experiments can only be carried out in a small number. Experiments with relatively large-capacity extractor equipment will certainly not have as high accuracy as the process parameters obtained by small-capacity extractor equipment; Then a constant CO2 extractor capacity can no longer meet the experimental requirements, so we have introduced two CO2 extractors with different capacities (1L and 5L);
You can freely choose the appropriate container in the experiment, for example, use a 0.5-pound (1L) extractor Small-scale experiments are carried out on the equipment. When the experiment is successful, 2.5-pound (5L) extractor equipment is used to scale up the experiment to confirm the reliability of the process data and the possibility of large-scale production.

Industry CBD Oil CO2 Extraction Machine/CO2 Essential Oil Extraction Equipment
The supercritical CO2 extraction machines are used to extract essential oils, including CBD oil, from hemp and cannabis plants. These machines operate by using high pressure and temperature to convert CO2 into a supercritical state, where it can penetrate into the plants’ tissues. The CO2 is used as a solvent to extract the desired compounds, including CBD, terpenes, and other cannabinoids, which are then separated and collected.
Industrial scale industry CBD oil CO2 extraction machine/CO2 essential Oil extraction equipment is available in different capacities, ranging from 10L to 9000L large-scale industrial extractors. The capacity of the machine depends on the size of the extraction chamber and how much plant material can be processed at once.
Fully automatic control of the entire process operation, automatic acquisition of data record storage, remote monitoring, and remote technical support is available with some BIT CO2 extraction machines.
The CO2 extraction process is known for producing high-quality, pure, and natural extracts from hemp and cannabis plants, free of any harmful chemicals and solvents. The extracts retain all the beneficial compounds, including terpenes, flavonoids, and other cannabinoids.

Terpenes and Full-spectrum CBD oils
Terpenes are organic compounds that are found in plants, including cannabis and hemp. They are responsible for the distinctive aromas and flavors of different strains and varieties. Terpenes are also believed to have therapeutic effects, including anti-inflammatory, anti-anxiety, and pain-relieving properties. CO2 extraction preserves the terpenes in the final product, allowing for a more complete and effective experience.
Full-spectrum CBD oils extracted using CO2 extraction contain a range of cannabinoids, including CBD, THC, CBG, and others, as well as terpenes and other beneficial compounds. This is known as the “entourage effect,” where the combination of these compounds produces a more significant therapeutic effect than when taken individually. The entourage effect is believed to enhance the therapeutic benefits of CBD oils, making them more effective for a range of conditions.
What is Supercritical CO2 Extraction?
There are many solvents that can be used for supercritical fluid extraction. Different solvents have different critical properties, and different extraction processes require different solvents. Each solvent has different critical properties, such as temperature and pressure, that affect its solvating power, selectivity, and efficiency. The solvents that can be used for supercritical fluid extraction include ethane, ethylene, propylene, carbon dioxide, etc. CO2 is the preferred solvent.
- Supercritical CO2 extraction is a process that involves using CO2 in its supercritical state as a solvent to extract desired compounds from a variety of materials. Supercritical CO2 refers to CO2 that has been heated and pressurized beyond its critical point, where it exhibits both gas and liquid-like properties.
- In the extraction process, supercritical CO2 is passed through the material to be extracted, where it dissolves the target compounds. The solubility of the target compounds can be controlled by adjusting the pressure and temperature of the CO2, allowing for selective extraction of specific compounds. The CO2 is then collected and depressurized, causing it to revert to gas and leaving behind the extracted compounds.
- Supercritical CO2 extraction is a versatile and effective method for extracting a wide range of compounds, including essential oils, lipids, and cannabinoids. It is also considered a safer and more environmentally friendly alternative to traditional solvent-based extraction methods, as it produces pure extracts without leaving behind any residual solvents or contaminants.
Supercritical CO2 extraction can be carried out near room temperature (35-40°C) and under the cover of CO2 gas, which effectively prevents the oxidation and escape of heat-sensitive substances. Therefore, the active ingredients of medicinal plants are maintained in the extract, and the substances with high boiling point, low volatility and easy pyrolysis can be extracted at a temperature far below their boiling point;
- Select a suitable solvent such as CO2 to operate at a lower temperature and an oxygen-free environment to separate and refine heat-sensitive substances and easily oxidized substances;
- Supercritical fluid has good permeability and solubility, and can quickly extract active ingredients from solid or viscous raw materials;
- Reduce the density of the supercritical phase, it is easy to separate the solvent from the product, there is no solvent pollution, there is no phase change process in the recovery of the solvent, and the energy consumption is low;
- It has the dual functions of distillation and extraction and can be used for the separation and purification of organic matter.
- CO2 has good mutual solubility with most organic compounds, and CO2 liquid has greater volatility than extractives, which makes the separation of extractants and extracts easier;
- CO2 extraction allows for precise control over the extraction process, resulting in consistent and reproducible results;
- The critical pressure (7.38MPa) is low and easy to reach; The critical temperature (31.1℃) is low and the enthalpy of vaporization is low, which is more suitable for industrial production;
- Good selectivity can be adjusted to extract specific compounds by varying temperature and pressure conditions, supercritical CO2 exhibits excellent solubility for low molecular weight aliphatic hydrocarbons and low polar lipophilic compounds, such as esters, ethers, lactones, etc.;
- The CO2 has chemically inert, has no danger of combustion and explosion, no toxicity, no corrosiveness, no erosion to equipment, and no pollution to products and the environment; and cheap, high-purity CO2 is easy to obtain;
- High-quality extracts that are free of residual solvents and contaminants. In the extraction system, a high concentration of CO2 has the effect of sterilization and anti-oxidation on the product.

How it Works?
The extremely low surface tension, low viscosity, high diffusivity, and tunable solvent strength of supercritical CO2 make it an ideal solution for a wide variety of industrial and scientific applications.
- The biomass is dried to a moisture content of less than 10%;
- Grind biomass to 40-60 mesh;
- Put the biomass into the extraction basket and put it into the extraction vessel;
- Start the CO2 extraction machine, introduce CO2 gas into the extraction vessel and create a supercritical CO2 fluid;
- Adjust the pressure, temperature, and CO2 flow in the extraction vessel to meet the requirements of the extraction target of biomass;
- Adjust the pressure and temperature of the separation vessel group according to the requirements of the extraction target, so that the CO2 fluid loses the supercritical state to a liquid so that the CO2 extract is successfully separated from the gas, and different CO2 extracts (heavy components and light components);
- The CO2 liquid is introduced into the gas intermediate storage tank in a closed loop;
- The CO2 liquid starts from the gas storage and the intermediate storage tank, and passes through the filter to create the supercritical CO2 fluid again for the next cycle;
- After the allotted run time, the system is depressurized by releasing CO2 through Separator 1 or 2 to obtain the CO2 extract.
