摘要

Crystallisation or precipitation apparatus with reduced deposition of crystals on its surfaces has a microstructure of ribs and grooves on the surfaces which contact crystallisate, solutions or mother liquors, so that they are self-cleaning. An Independent claim is included for a method for crystallisation or precipitation from solutions using the apparatus.
