PROBLEM TO BE SOLVED: To improve an operation rate of an automatic ice-making machine by preventing the firm attachment of oxide to an ice-making part. SOLUTION: A refrigerant is circulated and supplied to an evaporation pipe 14 mounted on an ice-making plate 10 from a freezing system 12 to cool the ice-making plate 10. The ice-making water in the ice-making water tank 20 is supplied to the ice-making plate 10 by driving a circulating pump PM to produce ice blocks M. When the ice blocks M are produced, an ice-making process is transferred to a deicing process, and the ice-making plate 10 is heated by a hot gas circulated and supplied to the evaporation pipe 14, whereby the ice blocks M are dropped from the ice-making plate 10 and discharged and stored in a stocker 16. The ice-making process and the deicing process are alternately repeated, and the ice-making operation is stopped when an ice storage detecting switch 40 detects that the stocker 16 is filled with the ice blocks M. The circulating pump PM is periodically driven to supply the ice-making water to the ice-making plate 10, in a state that a full state is detected by the ice storage detecting switch 40.
