Abstract
An installation for continuous production of liquid ice from a solution, including a circulation tank, a pump, a refrigeration circuit for cooling solution passing through at least one tubular element, causing the formation therein of ice crystal nuclei and small pure ice crystals, a liquid separator-regenerative heat exchanger, a crystal growth vessel into which the cooled solution containing ice crystal nuclei and small ice crystals is discharged, and an ice separator fed from the ice crystal growth vessel, in which pure ice crystals are separated from concentrated solution which is returned to the circulation tank, the pure ice crystals being continuously discharged from the ice separator. A method for continuous production of liquid ice is also described.
