Example of a fluidized bed crystallizer

The crystals are fluidised at the bottom of the crystallizer using an external axial pump which contains the mother liquor in the upper part and resends them to the crystallizer.

The residence time may exceed 10 hours.

However, this powerful technology requires frequent cleaning.
