1. Introduction

 The technique of super critical fluid extraction (SCFE or SFE) is a new type green separating technique with wide adaptability, which is rising in the modern world. with this technique, during the extraction process. no chemical agent is needed; no pollution is done to the separated substance, so as to fully meet the people's green requirements to medicine, food, health products, and cosmetics Also, this technique boasts the feature of high extraction effect, high quality, low extraction temperature, low energy consumption. And without pollution, especially suitable for the extraction of heat-sensitive and active substances. This device can extract widely volatile oil, alkaloid, and phenol and other medical elements from animals and plans.

2. Co2 Supercritical fluid extraction (SFE)-1st choice for aroma extraction,decaffeination,defatting,pesticide removal, phytoextraction,sterilization.

As an industrial pioneer in applied supercritical carbon dioxide extraction, offers its services for developing and production of healthy ingredients. Based on our long term experience we form strong partnerships with the food, beverage, pharmaceuticals, fragrance, cosmetic industries and related industries.

SFE is not only the gentlest extraction method for sensitive feedstocks; it also delivers a number of additional, compelling advantages:

• 100% natural, safe, inexpensive and environmentally responsible solvent
• Residue-free end-products
• Selective process control
• Improved quality and yield
• Fully scalable process

   4. Advantages of  Supercritical CO2 Extraction Device

  Low critical temperature, and it is suitable for extraction and purification of heat sensitive compound. Being capable to provide inert environment to avoid oxidation of products and affection of effective content of extracts. Fast extraction speed, no toxicity, non-flammable, safe application and no pollution upon environment. No residue of solvent. The extraction tank adopts quick-open structure; seal ring adopts special material, deformation little and Equips with the pressure auto-trace system. It can be designed and manufactured as per "GMP" standard.

  Supercritical CO2 Fluid Extraction makes the extracted oil and powder will be 100% pure, without any impurity or heavy metal.

   

  For examles,the technical could be used to extract effective compositon from chian-herbal-medicine,separate lipid compoud in compound in chemistry industry,and so on.The details as follows;1.It can achieve the biology active molecule,alkaloid and separating of the heebal materials2.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 mainy on the extracting for VE 5.To extract all kinds pf active materials(natural or synthetic), and remove the un-need molecutle(for example it can remove the pesticide when extract the vegetables)or residue material,so that to get the purity materials.6.The manutacturing on various natural antiseptic or oxidation resistance extracting materials,such as basil,scarlet sage,thyme,garlic,onion,chamomile,chill powder,linquorice anise seed etc.
