Five-zoning simulated movable bed chromatography device

The invention discloses a five-section simulated moving bed chromatographic equipment comprising five sections, each of which is connected in series by 1 to 4 chromatographic column. The exit end of previous chromatographic column is connected with the entrance end of the following one by a one-way valve, and the exit end of the last is connected with the entrance end of the first one. The entrance end of each chromatographic column is connected with extracting solution exit pipeline enriching different components, raffinate exit pipeline, and mobile phase exit and entrance pipeline by switch-type valve. The invention realizes completely automated operation in industry chromatographic fractionation process to make sure the stabilization and reliability of product quality, and the method has a high separating efficiency, a sample preparation, a high resolution, a good stability, a rapid speed and a low cost.
