ICE MAKING METHOD AND DEVICE BY SUPERCOOLING BRINE

摘要

PROBLEM TO BE SOLVED: To provide an ice making device capable of stably making ice regardless of the variation of concentration of brine supplied to a supercooling heat exchanger in accompany with the variation of ice making quantity, and free from problems such as freezing of brine in the supercooling heat exchanger. SOLUTION: In this ice making method for supercooling the brine by vaporized latent heat of liquid refrigerant supplied from a freezer by the supercooling heat exchanger 1, and then releasing the supercooled state of the brine to make ice slurry 13 in which the brine and small pieces of ice are mixed, the difference between a temperature of the supercooled brine at an outlet of the supercooling heat exchanger 1 and a temperature of ice slurry after releasing the supercooling is kept constant.
