Provided is a means for easily producing a plurality of types of flake ice having different freezing points and roughly uniform solute concentration. In this flake ice production device 10, a drum 11 includes an inner cylinder 22, an outer cylinder 23 surrounding the inner cylinder 22, and a clearance 24 formed between the inner cylinder 22 and the outer cylinder 23, and a refrigerant supplying unit 29 supplies a refrigerant to the clearance 24. A rotating shaft 12 rotates about the central axis of the drum 11. A spraying unit 13 rotates with the rotating shaft 12 and sprays brine toward the inner peripheral surface of the inner cylinder 22. A scraping unit 14 scrapes off flake ice that is generated as a result of brine sprayed from the spraying unit 13 becoming adhered to the inner peripheral surface of the inner cylinder 22, which has been cooled by the refrigerant supplied to the clearance 24.
