Abstract

The invention discloses an extraction method and the apparatus thereof. The method according to the invention comprises the following steps: crushing and soaking the raw material, and then extracting, wherein the extracting step is carried out under a 18˜33 kHz nonlinear vibration, using water as solvent, under 25˜35 MPa pressure and at 0˜50° C. temperature, thus obtaining a extract which contains the active components of the raw material. The method according to the invention also provides an apparatus for the nonlinear critical extraction. The applications of the method and apparatus according to the invention allow to extract the Chinese traditional medicines and plants at room temperature, thus not only ensuring the biological activity of the components in the medicines and plants, but achieving the substantial full-composition extraction of the Chinese traditional medicine and plants, as well as overcoming the disadvantages of the extract technology in the prior art which would destroy or partially extract the biological activities of partial components. Therefore, the method and apparatus of the invention can be widely used in the fields such as the Chinese traditional medicines, chemical engineering, food, etc.
