Abstract

PURPOSE: To purify with high purity and high yield an intended crystal component from crude raw material crystals by providing a purification stage and a recovering stage in a refining column, removing the crystals purified in the respective divided chambers once to the outside of the column, and cooling the same forcibly then feeding the crystal into the next chambers.
CONSTITUTION: A purifying stage which is the stage above a chamber 3 having a supply port 10 for raw material and a recovering stage which is the stage below the chamber 3 are provided to a purification column 1. The crystals discharged through the crystal discharge ports 8 of the respective chambers 3 in the purification stage are cooled forcibly with a cooler 9 and are then supplied into the next purification chambers, and the liquid discharged through liquid discharge ports 5 is supplied from the corresponding chambers to the previous purification chambers. The liquid discharged from the first purification chamber to be supplied with a crude raw material crystal through a supply port 10 for raw material is cooled with a cooler 9' and is thus crystallized, whereafter the crystal is supplied into the lower recovering stage. In the recovering stage as well, the discharged crystal is supplied to the next crystal supply chamber for higher purity similarly, and the discharged liquid is supplied to the previous crystal supply chamber for lower purity.
