We are pleased to announce the successful completion of the development of the CS30 Freeze Granulator, the world’s first mass-production freeze granulation process capable of continuous production, which we have been developing through our ongoing R&D efforts.

Freeze granulation is a process in which a liquid material is atomized into a low-temperature environment and rapidly frozen. The moisture contained in the frozen granules is then removed through a freeze-drying process by sublimation, resulting in the production of dry powder materials. Granules produced through freeze granulation are spherical in shape, exhibit excellent flowability, and offer low density while maintaining a high degree of homogeneity.

Freeze Granulator CS30 is a continuous freeze granulation process. Liquid nitrogen is supplied to the outer layer of the jacketed chamber to control the process temperature. The evaporated nitrogen gas in the outer layer is supplied to the inner layer of the chamber. A liquid material is atomized into the inner layer by a two-fluid nozzle and droplets get frozen by contacting with the nitrogen gas. Process temperature can be controlled by adjusting the supply amount of liquid nitrogen. Frozen granules are collected in the container installed at the bottom of the chamber. The collected frozen granules are freeze-dried using either a conventional freeze dryer or the RHEOFREED. By connecting multiple freeze dryers to CS30 and automatically switching connections, it is possible to process as semi-continuous production.

Through this product, we remain committed to providing greater added value and supporting the advancement of our customers’ projects.
