PROBLEM TO BE SOLVED: To provide an ice grain manufacturing method and an ice grain manufacturing device that can significantly restrain cracked or chipped ice grains from being generated.SOLUTION: An ice grain manufacturing method of manufacturing ice grains comprises: a dropping step of dropping a liquid material into a liquid refrigerant a first cooling step of cooling the dropped liquid material under the action of the liquid refrigerant to generate ice grains a separating step of separating the generated ice grains from the liquid refrigerant a holding step of holding the ice grains separated from the liquid refrigerant without bringing them into contact with the liquid refrigerant and a second cooling step of immersing the held ice grains in the liquid refrigerant again to cool the ice grains.SELECTED DRAWING: Figure 1
