Method for purifying and separating a target compound from a crystal suspension of the target compound in a mother liquor

摘要

The method involves supplying a suspension stream in a process chamber (7) to a supply-end, and delivering a mother liquor stream (2) from the chamber from a suspension stream under retention of crystals and formation of crystal bed (5). Force that is applied at a drive shaft (18) in a longitudinal direction in normal operation is continuously adjusted upwards. The shaft is rotatably supported around a longitudinal axis in mountings. Two bearings e.g. guiding bearing and radial bearing, are arranged in one of two mountings such that the bearings accommodate the force in one of the mountings.
