factory Supercritical CO2 extracting machine

   The Super Critical fluid technology is a new-type separation technology in modern chemical seperation.The Super Critical extaction takes CO2 as the solvent.As CO2 fluid under Super Critical state has larger density and dielectric constant,large dissolvability against substances,which can change abruptly when pressure and temperature chnage therefore it has not only the selection of dissolvability against some substances,the separation of the solvent with the extracted substances is also easily.The super critial CO2 extraction is specially suitable for extraction of fat-soluble and heat sensitive substances with high boiling point,and is suitable for fine separation of different components,i.e.Super Critical fine distillation. 

    Take CO2 as the solvent to make extraction and purification upon a lot of products such as biological products,foodstuff and medicines.

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.
