Abstract
A hollow, rotating drum is horizontally supported in a vessel or crystallizer containing a brine such as sea water and has a plurality of nozzles projecting radially outwardly therefrom and having orifices having a smaller diameter than the nozzles. A liquified refrigerant is introduced through a conduit and a hollow shaft into the drum and is discharged as droplets into the brine while the drum is being rotated at high speeds in the brine. Upon getting into the brine, the refrigerant is vaporized and takes away heat of the brine, which is then refrigerated to form small crystals of ice.
