This literary grace extracts the bear tartaric acid in the plantain with the super and critical CO2.The super and critical CO2 extracts to take CO2 as super and critical fluid(SpercriticalFluid, SCF) because of the SCF physical property,such as density, and glues a degree and spreads functions to all enter to lie immediately in should the material liquid and of the air.The great commander for proliferation coefficient to compare its liquid of the super and critical fluid is near 10000%, glue the degree and air look like, but consumedly low in its liquid of glue a degree, this make super and critical fluid can the elephant air is similar to have very thin piping but high speed fluxion of cut through of characteristic.So SCF and have the dual characteristic of the liquid and air, the proliferation coefficient is big, gluing one degree small, permeate sex good.The melting agent of the super and critical CO2 turns the ability and liquid to near to very much, have superior of spread the quality function and fuse an ability, compared with the traditional liquid melting agent is a more ideal melting agent.The experiment proves super and critical CO2's extracting the application of the craft is the valid path that raises a product to get the rate and quality.Passing the control pressure and the change of the temperature or joining to guide and help an etc. method can make the melting agent of the super and critical fluid turn an ability in variety inside the very wide scope, attaining a purpose of extract the bear tartaric acid in a certain scope.For this literary grace use is hand over the experiment method research plantain to grow the bear tartaric acid to withdraw a craft.
