<p>The invention proposes a method and a device for continuously producing a crystallite, wherein a metered amount of seed crystals is fed continuously to the internal solution circuit of a crystallizer, in particular a DTB crystallizer, through a crystallization seed line from a seed generator preferably designed as a flash crystallizer. The amount of seed crystals fed is controlled by an electronic control system as a function of a measured value determined by a sensor, said value being representative of the particle size distribution of the crystallites in the solution in the internal circuit in the crystallizer. By way of a line, the seed generator receives a partial stream of the external solution circuit of the crystallizer, said external circuit being routed through a line. Excess fine crystalline suspension can be fed back to the external circuit from the seed generator by way of a return line.</p> |
