Freeze Granulator: CS220

World's first freeze granulator using a closed cycle system.

This is our latest generation freeze granulator (patented), the world's first closed-cycle system that can be scaled up. It adopts a dry cooling method that is free of liquid nitrogen, utilizing a unique high-efficiency cooling unit. By not using liquid nitrogen, it is possible to significantly reduce operational costs. The droplets that are atomized are frozen while suspended in the airflow by coming into contact with a low-temperature gas stream that is continuously supplied within the freeze granulator process. The frozen material is collected by the lower part of the freezing chamber or by a cyclone. By increasing the size of the collection container, it is possible to produce a large amount of frozen material at once. The collected frozen material is freeze-dried by the freeze dryer RHEOFREED. By connecting multiple freeze dryers to the freeze granulator and automatically switching connections, it is possible to achieve production that is close to continuous (semi-continuous production process).

Freeze Granulator: CS30

The world's first mass-produced freeze granulator capable of continuous production using patented technology.

This is the world's first mass-produced freeze granulator capable of continuous production using patented technology. Liquid nitrogen is supplied to the outer layer of a jacket-type freezing chamber, cooling the entire process. The nitrogen gas that evaporates in the outer jacket layer is supplied to the inner layer of the chamber. The liquid is sprayed into the inner layer of the chamber through a two-fluid nozzle, freezing upon contact with the cooling nitrogen gas. By adjusting the supply of liquid nitrogen, control over the process temperature is possible. The frozen material is collected in a dedicated recovery container installed at the bottom of the freezing chamber. By increasing the size of the recovery container, it is possible to produce a large amount of frozen material at once. The collected frozen material is freeze-dried using a general-purpose freeze dryer or the RHEOFREED freeze dryer. By connecting multiple freeze dryers to the freeze granulator and automatically switching connections, production close to continuous operation is achievable (semi-continuous production process).
