High-purity purification device combining DP-type crystallization apparatus and purification tower.
**Principle** By circulating a large volume of reaction liquid, a powerful vortex flow field is formed within the reactor. By continuously feeding raw materials into this vortex flow field, uniform reaction crystallization throughout the entire reactor is made possible, enabling the production of fine particles through continuous crystallization. **Features** Fine and sharp particle size distribution It is possible to continuously produce fine particles with a small particle diameter (around a few micrometers) and a sharp particle size distribution (good monodispersity). High productivity per unit volume The device capacity can be reduced through continuous production (approximately 1/5 to 1/10 compared to conventional stirred tanks). Others Short startup time. The unit structure allows for easy scale-up through numbering up, and the simple internal structure makes disassembly and cleaning easy.
