SUPERCRITICAL CO2 extraction machine

Part 1. Mechanism

Technique of super-critical extraction,

a advanced technical coming forth presently, is a new subject in the field of the modern chemical separating industry, which is applied widely in the field of extracting substance from plant.

There is a immediate relationship between dissolvable capability of Super-critical medium and it-selves density. Both pressure and temperature affect the dissolvable capability of Super-critical medium. Under super critical condition, put Super-critical medium together with material needed be separated to extract substance according to polarity magnitude, boiling point, and molecular weight. For substance extracted achieved at some pressures is not simplex, the condition should be controlled to achieve excellent quality of mixed composition, then, reduce pressure, increase temperature, to change the phase of Super-critical medium from liquid to gas. By this way, substance extracted is separated and purified. CO2 Super-critical extraction includes extraction and separation.

Part 2. Features

1. Super-critical extraction works at room temperature (range from 35℃ to 40℃) and extracts what we need in circumstance full of CO2 , which prevent availably thermal sensitive substance from oxidation or escaping. In this case, the effective composite from medical plants are remained. The material which has the attribute of high boiling point, low volatility and easy pyrogenation can be extracted in this way.

2. Super-critical extraction is the most cleanly method. Organic solvent being used in whole process, there isnít any residual solvent, which avoids deleterious substance existing and prevents environment from polluted, therefore ensures that the product yielded keeps 100% natural property.

3. Extraction and separation act as a whole part during production. When CO2 Saturating solute flow into the Segregator, CO2 and the substance extracted coming into being two phases (gas and liquid) rapidly to separate due to the pressure declining or the temperature varying. By this way, production efficiency could be greatly improved, which decreases energy sources consumed and reduces cost.

4. CO2 , a kind of inertial gas, which isnít able to burnt , and possesses the attribute of no taste, no smell and innocuity, doesnít occur the phenomena of chemic reaction in the process of extraction.

5. CO2, a kind of low-cost gas with high purity, is very easy to achieve and can be used again and again , which greatly reduces cost of production.

6. Ether pressure or temperature may act as adjust parameter during the process of extraction, in other words, changing pressure or temperature may reach the aim of extraction. That is, changing temperature only may be separated substance when pressure is settled; on the contrary, changing pressure only may be separated substance when temperature is settled. Therefore, the technical is easy, and production efficiency is high.

Part 3. Application

Possessing unique characteristic, CO2 Super-critical extraction has being widely used in many fields. For example, the technical could be used to extract effective composition from china-herbal-medicine, separate lipid compound in medical industry; extract hop or pigment in food industry; refining nature or synthetic fragrance product; separated compound in chemistry industry, and so on. The details as follows;

1. It can achieve the biology active molecule, alkaloid and separating of the herbal materials

2. It can be used in the microscopic organism lipoid, and it can recycle the lipoid, and remove the lipoid from glycoside and protein.

3. It can extract various anti-cancer ingredients from many herbal materials, especially the extracted product pacilitaxel which extracted from yew skin, branches and leaves.

4. Vitamin, mainly on the extracting for VE

5. To extract all kinds of active materials (natural or synthetic), and remove the un-need molecule(fro example it can remove the pesticide when extract the vegetables) or residue materials, so that to get the purity materials.

6. The manufacturing on various natural antiseptic or oxidation resistance extracting materials, such as basil, scarlet sage, thyme, garlic, onion, chamomile, chili powder, liquorice, anise seed and so on.

The advantaged design different with others

1. Continuous process of extraction

Instead of adopting the method of extracting discontinuously, working in a continuous way, this instrument is more effective then before(1times higher).

2. Automatically assemble and un-assemble material

The process of loading and unloading material from the bottom of the instrument to extraction kettle is controlled by computer. Instead, before the apparatus was improved, workers had to climb up the top of the kettle to tear down the bolt in the kettle, then carry the store kettle and place it in the vesselóthis is really a clumsy and not safe way.

3. Accurate extraction pressure and separation pressure

CO2 injection pump controlled by computer traces the extraction pressure automatically in a way of frequency modulation, and the separation pressure is controlled automatically by pressure adjustment , which make the precision of extraction pressure and separation pressure be controlled in a steady condition required. In this way, high purified substance extracted could be yielded.

4. High efficiency of usage of CO2

The loop designed in the instrument utilizes CO2 circularly, which reduces the release of CO2 greatly. (without the circular loop, the measure of pressure balance is adopted after test finished, which lead to a mount of CO2 lost .The pressure ranges from 6 MPa to 8MPa when gas is released, and with a big noise, it will last for a long time in this process)

A new method of fluid spreading around adopted makes the fluid (CO2) contact with solute evenly, which speeds solution, reduces time of extraction greatly, and increases production ultimately.

5. Friendly design

The instrument is controlled by computer which adopts man-machine conversation and voice indication. With multiple pressure protection, temperature protection and safety light screen protection, the instrument could prevent operators from hurt effectively. Operators will operate the instrument in a friendly condition.
