Perface to the 25L×2 Supercritical CO2 Extractor
The prototype of the 25L×2 supercritical CO2 extractor is HA220-40-48 supercritical CO2 extraction machine; P-25D has two 25L extraction kettles (extractor) with a maximum working pressure of 400bar, and two separation kettles (separator) with a capacity of 10L and a maximum working pressure of 200bar ；
Why is this supercritical CO2 extraction machine is 24L or 25L?
Then why the supercritical CO2 extractor capacity of the past model is only 24L instead of 25L? Here is a small story. In the past China’s pressure vessel regulations, for safety reasons, pressure vessels greater than or equal to 25L need to be tested by the government’s quality management department, and will cost some fees, so users only choose 24L for convenience. .
Therefore, China’s supercritical CO2 extraction machine used to have these models: 24L×2, 24L×3, 24L×4.
But now with the policy change, it has been changed to 25L×2, 25L×3, 25L×4.
This can be regarded as a workaround between enterprise and government management.
About the safety of Huaan supercritical CO2 extractor
In fact, the safety of pressure vessels is the most important anyway, and there is no room for sloppy;
Huaan is one of the units that formulate China’s supercritical fluid system pressure vessel standards. Huaan supercritical CO2 extraction equipment strictly follows from the overall structure to many details at the beginning of the design.
Design in strict accordance with national standards and ASME standards, and strictly control all aspects of material procurement, production, assembly, testing and acceptance to ensure safety.

Supercritical CO2 extraction & fractionation machine.
This is a P-25D capsanthin extraction machine equipped with a supercritical CO2 fractionation column.
This P-25DF is used in Thailand to extract capsaicin and chili oil, and it is suitable for the extraction of cannabis/hemp/hash oil, because it can separate most of the useless substances in the fractionation process, such as wax, chlorophyll, etc., saving use cost.
Supercritical CO2 fractionation column is also called supercritical CO2 rectification column in China. The configuration of this machine’s fractionation column is as follows:
Equipped with a water jacket circulating heating system, the temperature can be adjusted. Due to process requirements, a low temperature coil is equipped in the water bath, and the control temperature is less than about 10 ℃ at room temperature.
Specifications Φ60× 6× 3500 / 30MPa temperature control with four gradients
According to the process requirements, the user can choose the packing with relevant specifications. (With filler 5 × 5mm)
Plant essential oil extraction
Essential oils are extracted from the leaves, flowers, seeds, fruits, roots, bark, resin, wood heart and other parts of plants by steam distillation, cold pressing, liposuction and solvent extraction. They have a high concentration of aroma and Volatile substances.
In addition to the essential oils that can be extracted from a certain part of the plant, some plants can extract essential oils in several parts. For example, bitter orange can extract essential oils from the buds, leaves and fruits of three parts.
Not all plants can produce essential oils, only plants that contain balsam glands can produce essential oils. The distribution of balsam glands in different plants is different, some are on petals, leaves, rhizomes or tree trunks.
Ingredients of plant essential oils
Essential oils contain many different ingredients. Some essential oils, such as rose, can be formed by combining more than 250 different molecules.
Various essential oils are composed of different organic compounds.
These compounds are soluble in alcohols, oils, emulsifiers, ethers and chloroform. The aroma and therapeutic properties of each essential oil are related to the composition and concentration of the constituent essential oil molecules.
The ingredients mainly contain the following categories: alcohols, aldehydes, acids, phenols, esters, ketones and terpenes.
How to extract essential oils
It is the most commonly used extraction method. Distillation technology and distillation method determine the quality of essential oils.
The distillation method is very convenient and does not require the use of chemical solvents, so the application is still very common now. Roses, lavender, rosemary, geranium, etc. mostly use this method.
An ancient method for extracting precious floral scents. The oil is used to absorb the aroma molecules, and then the “original essence” is extracted with alcohol. After the alcohol evaporates, the remaining aromatic essential oils are left behind.
Squeezing method (extrusion method)
By cutting, crushing, squeezing and other methods, the plant water and aromatic essential oils are separated from the raw materials to obtain a mixture of water and oil, and then centrifugation, filtration and other methods are used to separate the oil and water to obtain the essential oil.
Refine flowers that are delicate and not suitable for high-temperature distillation extraction. Essential oils generally labeled “absolute” on the market. Use alcohol, ether liquid butane and other solvents to repeatedly pour on the plants, and then separate the solvent containing essential oils, and then obtain essential oils by low-temperature distillation, which can replace liposuction. Such as cinnamon, benzoin, etc.;
The latest extraction method is applied in countries with advanced technology. It uses high-intensity, high-energy ultrasonic waves to improve the defects of traditional solvent extraction methods, reduce heat loss caused by temperature, and extract more biologically active ingredients, so that the quality of essential oils is good, and the extraction efficiency is also high
Supercritical carbon dioxide extraction
The whole process is carried out at low temperature, and the essential oil is dissolved from the plant under very high pressure, so the fragrance is not affected by heat.
The principle is: the density of carbon dioxide under high pressure or low temperature is close to that of liquid, while retaining some of the properties of ordinary gas. It is called “supercritical fluid”, which has strong dissolving ability.
Due to the short extraction time, there will be no chemical reaction between the solvent and the flavor. In addition, due to the huge equipment and high cost, it is only used for precious essential oils, and the products are marked with CO2;
The supercritical carbon dioxide extraction method enables the extraction of essential oils at room temperature without using solvents harmful to the human body, and can better protect the natural activity of the product. It is a more advanced “green separation technology”.
Molecular distillation extraction
Molecular distillation technology uses the difference in the free path of molecular motion of different substances to realize the separation of substances, so that it can realize operations far away from the boiling point. It has the characteristics of low distillation pressure, short heating time, and high degree of separation, which can greatly reduce the separation of high boiling point materials. Cost, excellent protection of the quality of heat-sensitive materials.
Molecular distillation extraction technology has been widely used in the extraction of high-purity substances, and is suitable for the extraction and separation of natural substances. For example, in the extraction of cannabis/hemp/hash oil and agarwood essential oil, molecular distillation extraction technology is used in the final process.
Traditional separation methods such as steam distillation, pressing and extraction have some shortcomings in the processing process. For example, natural active ingredients are easily destroyed, and organic solvents harmful to the human body may remain in the final product.
