The DODGEN Melt Crystallizer is a high-efficiency purification unit integrating swirl distribution and falling-film crystallization technology. It adopts a vertical tube-bundle structure, in which the feed forms a spiral liquid film inside the tubes, and crystallization is achieved via indirect cooling by an external coolant. The core advantages lie in enhanced heat-transfer performance and improved crystal uniformity. DODGEN can supply a single unit with a capacity of 10 kg/h, as well as a single unit with a throughput of 10 t/h. The system has been industrially applied in continuous purification processes for acrylic acid, caprolactam, and related chemical intermediates. High-efficiency heat transfer, stable crystallization; Anti-blocking and anti-polymerization, reliable operation; High operating flexibility, precise control; Low system pressure drop, significant energy savings; Easy cleaning and maintenance, short downtime.
