CS220 is our latest generation “liquid nitrogen-free” dry cooling freeze granulator that uses patented technology with our original high-efficiency cooling system. As the process does not use liquid nitrogen, it has advantages in safety and environment, and can reduce the installation and operating cost. Our latest generation CS220 is the world’s first closed-cycle system that can be scaled up for mass production. Since liquid nitrogen is not used in the process, operating costs can be significantly reduced. The atomized droplets come into contact with the ultra-low temperature gas flow that is continuously supplied into the process, and instantaneously get frozen. Frozen granules are collected at the bottom of the freezing chamber and a cyclone. The collected frozen granules are freeze-dried using a freeze dryer RHEOFREED. By connecting multiple freeze dryers to CS220 and automatically switching connections, it is possible to process as semi-continuous production.
