KTI ice slurry generators are equipped with a heat exchanger which contains a rotating scraper inside and constantly removes the water freezing at the edge. The speed of the scraper thereby determines the ice particle sizewhile the flow rate of the brine or saline water is the ice-water ratio is predefined. This allows the mass fraction of solid ice particles to be adjusted. The fewer ice particles are contained in the ice slurry, the easier it is to pump, but it also contains less "cooling energy".
Another way to make ice slurry is to mix water and solid ice in a special tank including an agitator. This method is ideally used if a KTI flake ice plant or KTI plate ice machine is already available.
