Patent ID: 8241492

Claim:
A simulated moving bed chromatography device comprising: a minimum of one stationary pipe with a plurality of inlet/outlet channels; a rotary device connected to the stationary pipe(s), wherein the rotary device comprises a plurality of rotational flow distribution channels employed to individually received/transfer fluid(s) from/to the inlet/outlet channels; a stationary segmented vessel that communicates with the rotary device, wherein the stationary segmented vessel comprises a plurality of stationary flow distribution segments, a plurality of stationary phase segments and a plurality of outer fluid transfer segments, wherein the radial direction first partition plates are set up between the adjacent stationary flow distribution segments, between the adjacent stationary phase segments, between the outer fluid transfer segments; a fluid moving device to circulate the fluid; a driver to rotate the rotary device for a fixed angle, wherein the one end of the rotational flow distribution channel of the rotary device communicates with the corresponding stationary inlet/outlet channel, the other end communicates with the next corresponding stationary flow distribution segment of the stationary segmented vessel; a first circulation mechanism within the stationary segmented vessel, which refers to: the first passage channels of the first partition plates in the outer fluid transfer segments and the first passage channels is: a plurality of openings or channels on the first partition plate within the outer fluid transfer segments, or a plurality of bypass channels for the first partition plate of the outer fluid transfer segments, or a flow channel formed by the removal of the first partition plate between the two adjacent outer fluid transfer segments.
