The invention concerns a rotary distribution apparatus (30) for distributing process liquids, typically in ion exchange and chromatographic separation in the processing of sugar juice. The apparatus includes a core (2) into which fixed process liquid supply pipes (3) extend and annular fluid distribution chambers defined between the core and an outer shell (4) which rotates around the core. Rotating pipes (5) are provided which rotate with the shell and which are connected between selected distribution chambers and selected ports in a rotating indexing disc (6) which rotates, with the shell, relative to a stationary indexing disc (7). The arrangement is such that as the rotating disc rotates, different streams of process liquid streams fed to the rotating disc through the rotating pipes are introduced to fixed ports in the stationary disc. The latter ports are arranged to feed the streams selectively to selected destinations. According to the invention interstage pumps operating to pump the process liquids are mounted to rotate about the core with the rotating pipes and the rotating indexing disc. This leads to a particularly simple design compared to conventional simulated moving bed configurations with fixed pumps. |
