Abstract

The invention discloses an extracting separating device by utilization of an impregnation method. The device comprises a solvent tank, an impregnating tank, a plurality of macroporous resin columns, a receiving tank, an eluent tank and a vacuum system, wherein the solvent tank, the impregnating tank, the plurality of macroporous resin columns, the receiving tank and the vacuum system are sequentially and serially connected end to end, so that a loop is formed; a pipeline, between the impregnating tank and the macroporous resin column firstly connected with the impregnating tank, is provided with a branched pipeline which is connected with the eluent tank, and the branched pipeline is provided with one valve; the receiving tank is provided with a branch which is connected to the outside and is provided with one valve. The device disclosed by the invention has the advantages that the use amount of solvent can be reduced, the extraction ratio of effective ingredient is increased, and the production cycle is shortened.

Description

technical field [0001] The invention relates to an extraction and separation device, in particular to an extraction and separation device by dipping method, which belongs to the technical field of medicine. Background technique [0002] The dipping method belongs to the static extraction method, which is a simple and commonly used extraction method in which medicinal materials are soaked at room temperature or heated to extract the active ingredients contained in them. The operation is simple and easy, but the time required is long, the amount of solvent is large, and the leaching rate of active ingredients is low. In addition, in the impregnated state, the solid-liquid space is usually in a static state, the utilization rate of the solvent is low, and the active ingredients are not completely leached. Even if the dipping is repeated, the stirring is strengthened, or the solvent circulation is promoted, the leaching effect can only be improved, and a high-concentration acti...
