Abstract
Provided is an ice-making device that can be easily miniaturized. The ice-making device includes: a freezing tank 12 that stores brine; and a flake ice making part 15 arranged inside the freezing tank 12 and capable of being immersed in the brine Ws, wherein the flake ice making part 15 includes: a disc part 26 that causes a refrigerant, which is supplied from a freezing machine 14, to circulate therein, the disc part 26 having plate surfaces 26a, 26b that generate ice of the brine Ws; a nozzle part 41 that provides a flow of the brine Ws to the plate surfaces 26a, 26b; and a sweeping part 23 that is displaced with respect to the plate surfaces 26a, 26b to separate the ice generated on the plate surfaces 26a, 26b from the plate surfaces 26a, 26b.
Claims16
An ice-making device comprising:
- an ice slurry production tank storing brine;
- and
- an ice production unit arranged inside the ice slurry production tank, the ice production unit being able to be immersed in the brine, wherein
- the ice production unit includes:
- an ice-making plate circulating refrigerant, which is supplied by a freezing machine, inside thereof and including an ice-making surface, which generates ice of the brine on at least one surface thereof;
- a flow forming unit providing a flow of the brine to the ice-making surface;
- and
- a sweeping unit being displaced with respect to the ice-making surface to separate ice generated on the ice-making surface from the ice-making surface.
An ice-making device comprising:
- an ice-making unit contacting brine;
- a first refrigerant path formed to pass through the ice-making unit and capable of causing a first refrigerant to flow;
- and
- a second refrigerant path formed to pass through the ice-making unit and capable of causing a second refrigerant, which has an evaporation temperature lower than that of the first refrigerant, to flow, wherein
- the second refrigerant cools the ice-making unit cooled by the first refrigerant.
(canceled)
An ice-making method performed using an ice-making device including an ice-making unit contacting brine, a first refrigerant path formed to pass through the ice-making unit and capable of causing a first refrigerant to flow, and a second refrigerant path formed to pass through the ice-making unit and capable of causing a second refrigerant, which has an evaporation temperature lower than an evaporation temperature of the first refrigerant, to flow, the ice-making method comprising:
- cooling the ice-making unit by the second refrigerant after cooling the ice-making unit by the first refrigerant.
An ice-making device comprising:
- an ice slurry production tank storing brine;
- and
- an ice production unit arranged inside the ice slurry production tank, the ice production unit being able to contact the brine, wherein
- the ice production unit includes:
- an ice-making plate having an ice-making surface;
- and
- a sweeping unit being displaced with respect to the ice-making surface to separate ice generated on the ice-making surface from the ice-making surface, wherein
- at least part of the sweeping unit has water-repellent coating.
