Main Introduction : 

This device usually be used for material extraction under the high pressure and suitable temperature (solid or fluid), Changing conditions in the separator to parse out dissolved substances in order to achieve the purpose of separation. The device is mainly composed of : extractionkettle, Separate kettle, CO2 high-pressure pump, entrainer pump, cooling system, CO2 basin, exergy transfer system, purification system, flowmeter, temperature-controlled system, safety protection device and so on. Attached device and the system can meet the needs of the main system of supercritical extraction and flow chart of requirements

 Commonly, Supercritical fluid extraction device adopts CO2 as the extracting media. The advantages as follows:

1) Convenient in operation. Can be used widely.

2) With an excellent optional function. Extracts can be gained optionally by controlling the pressure and temperature.

3) Low operation temperature. Can be extracted near to the room temperature, especially fit for the extracting of thermo-sensitive elements. The possibility of oxidation when contact with oxygen and reaction when meet rays are eliminated. The natural flavor of the extracts can be kept.

4) Extracting media and extracts can be separated easily. No leftover of CO2 on the extracts after extracting operation.

5) CO2 is a nontoxic, flavorless, noncombustible and cheap compound and can be recycle used.

The better features of equipment after comparing with similar products at home and abroad:

1.CO2 can be recycled, and be equipped with return circuit which saves gas, ensuring that the pressure of extraction kettle can be reduced under 4MPa after working, also making the Min. discharging amount. Adopt new methods of fluid distribution uniform fluid distribution, which makes CO2 fluid and solute uniform contact to speed up the dissolved, shorten extraction time, increase production

2.It adopts new method and new technology which can make CO2 residual gas in a cylinder under the net weight 1.5 Kg.

3.Each kettle has function of measuring and controlling temperature system, which can   effectively control the temperature of the thermal inertia

4.Extraction cylinder adopts quick-opening structure which developed by our company. It opens very easily, sealing is reliable, and the repeatability is good when CO2 swelling. It can be use for a long time without having to replace the sealing ring, which effectively solved the difficult problem of o-rings event of CO2 expansion. 

5.Pressure adjustment valve of each kettle is good at high precision, small volatility, well stability.

6.security system of double pressure protection

7.All the kettles are equipped with safe valve, implementing the overflow protection when overpressure ; In addition, the kettle is equipped with electric contact pressure table. It is good at protecting through artificially setting maximum pressure, carrying out overpressure stopping pump function.

8.The mixer is given priority to the auxiliary pump, mix them with electric contact pressure gauge, Pointers can use upper and lower limits of system pressure protection, overpressure activity pointer to pointer exposure limit, when the pump stop working

9.Extraction cylinder device has manual controlling system and automatic controlling system, making the manual and automatic dissolve into an organic whole. So that the controlling precision is greatly increased and it can reach 0.5%, the purity of the extracted components is higher

10.The extraction time is artificial for humanized design. When the equipment stops working, it can make a sound to warm the workers.

11.Function of device is complete, such as supercritical fluid extraction, supercritical fine particles preparation, determination of solubility of the solute

Technical parameter: 

 12.Device is running low noise, small vent noise, time is short
