Sub-critical fluid extraction technology is a new extraction and separation technology by using subcritical fluid as extracting agent, based on the principle of similar miscibility of organic compounds in the pressure container of airtight,low pressure and anaerobic, then get the final product.

Sub-critical fluid extraction technology is a kind of new oil extraction technology, not only provides the high quality raw materials for vegetable protein factory, but also provides a new way for Precious oil with good quality.

Sub-critical fluid extraction technology has many advantage: avirulent, harmless, environmental protection, no pollution, retaining extract active products not damage, no oxidation products, large capacity, energy saving, low running cost, easy separation with product.
