PROBLEM TO BE SOLVED: To manufacture a slurry ice by adjusting the content of ice without impairing the separability of ice crystal and inhibiting the smooth discharge of the slurry ice. SOLUTION: In a refrigerating cycle 2 composed of an evaporator 6, a compressor 3, a condenser 4 and an expansion valve 5, a supply pipe conduit provided with a supply pump 11 is connected with an inlet 6c of an inner pipe of the evaporator 6, and a discharge pipe conduit 8 is connected with an outlet 6d. A refrigerant of the refrigerating cycle 2 is supplied to an annular space formed between an outer pipe and an inner pipe of the evaporator 6 through an inflow port 6a, and discharged through an outflow port 6b. Further, a brine is supplied to the inner pipe of the evaporator 6 through a supply circuit 7 and a supply pump 11 to be stirred by a rotating member rotated in the inner pipe of the evaporator 6, the ice crystal produced on an inner peripheral face of the inner pipe of the evaporator 6 is liberated in the brine, and the slurry ice is discharged to the discharge pipe conduit 8. Further, a bypass pipe conduit 9 provided with a circulating pump 12 is mounted between the discharge pipe conduit 8 and the supply pipe conduit 7 at a downstream side of the supply pump 11.
