PROBLEM TO BE SOLVED: To provide a method and a device for making slurry ice by efficiently and continuously separating ice layers composed of ice crystal deposited on a heat conductive face of an inner face of an inner cylinder of a double cylinder, to stably and continuously make the ice friendly to the environment by applying the direct expansion-type cooling method using only a small amount of refrigerant, or applying the indirect cooling by a low temperature brine. SOLUTION: This slurry ice making machine forming a slurry ice making device is provided with the double cylindrical vessel 11 composed of the inner cylinder 17 for depositing ice crystal from an aqueous solution, an outer cylinder 18 forming a jacket-type channel 16 where the cooling medium for making the ice crystal flows, with the inner cylinder 17, a pressing roller for forming and separating a thin ice layer by the ice crystal deposited on the heat conductive face 17a of the inner cylinder 17, a pressing and separating means 15 composed of a rotary frame 13 supporting the roller 12 and being rotated in the inner cylinder, and a driving part 14a for rotating the rotary frame 13.
