FIELD: ice production equipment.
SUBSTANCE: cooling method involves spraying liquid mixture with the use of ultrasonic spraying unit operating with a given frequency and amplitude; cooling the resultant liquid mixture spray for obtaining cold mixture spray of non-liquid physical state with the use of gaseous coolant; performing freeze drying for practically complete dehydration of cold mixture. Cooling system includes spraying means, cooling unit to obtain cold mixture spray of non-liquid physical state and freeze drier, wherein spraying means is ultrasonic spraying unit and gaseous coolant is used in cooling unit.
EFFECT: reduced power inputs and cost, decreased size and dimensions.
