More Information
Summary:A countercurrent column crystallizer comprises at least one substantially horizontal stationary crystal bed support tray (22) positioned along the axial length of the column, and transport means to aid the travel of crystals through said support tray and along the length of the column. The transport means can, for example, comprise a plurality of substantially horizontal perforated plates (21) fixed to a support member (20) which is capable of being vibrated axially by an excitation device (23) to which the support member (20) is attached. The presence of the stationary support trays (22) reduces axial liquid back-mixing, thus improving column efficiency and product purity.
