Flake ice, ice slurry, production device of flake ice and production method of flake ice

Abstract

To provide an ice slurry which is excellent in a characteristic for cooling and cold-storing a cooled product, flake ice, the ice slurry, a flake ice production device which can efficiently produce the ice slurry, and a flake ice production method.SOLUTION: A flake ice production device 1 comprises a water tank 2 for storing fresh water, a nitrogen nanobubble supply machine 4 for supplying nitrogen nanobubbles to the fresh water in the water tank 2, supply quantity adjustment means 4a for adjusting a supply quantity of the nitrogen nanobubbles so that a chlorine concentration of the fresh water supplied with the nitrogen nanobubbles is equal to or lower than 0.1 ppm, and a dissolved oxygen concentration is equal to or lower than 1.0 mg / L, a flake ice production machine 5 for producing flake ice from the fresh water containing the nitrogen nanobubbles, and an ice slurry tank 6 for producing an ice slurry from the fresh water from the water tank 2 and the flake ice from the flake ice production machine 5.SELECTED DRAWING: Figure 1
