The crystalliser of the invention comprises a crystallisation vessel, an agitator, cooling means and a drive, and is characterised in that said drive provides said agitator with an oscillating motion, a reciprocating motion, and/or a rotating motion around an axis, with the proviso that the various points of said agitator move at substantially the same linear speed when the agitator is provided with a rotating motion around the axis. |
