The heat transfer tube 19 is provided with a plate (heat exchanger for ice making) 23 having good heat conductivity. While cooling the ice-making heat exchanger by flowing the primary refrigerant 20 inside the heat transfer tube, water 21 is sprinkled on the surface of the heat exchanger to grow ice 22 in layers from the surface of the plate.

On the other hand, the dynamic type ice making device (FIG. 5) improves the above problems (a) and (b) of the static type ice making device by including means for removing ice. The problem of () has not been completely solved, and the following problems still remain regarding the ice making efficiency. That is, as the ice layer grows and becomes thicker, the thermal resistance of the ice itself increases, so the ice-making heat exchanger 23 must be cooled to about -5 to -10 ° C, and the supply device of the primary refrigerant 20 is required. As a result, a compressor with a large power is required, and it is also necessary to remove the ice frequently (in one example, about once every 20 minutes).

Since the inside of the container is decompressed and evacuated below the triple point pressure of water, the sprayed water evaporates in a boiling state.
At this time, since the latent heat of vaporization is removed, the remaining water is cooled (self-cooling phenomenon) and freezes on the icing plate. That is, by continuously depressurizing and exhausting the inside of the container to a pressure equal to or lower than the triple point of water, heat exchange is performed in the form of a bidirectional phase change of water, and evaporation and freezing proceed simultaneously. As 1 kg of water at 0 ° C. evaporates, about 7.5 kg of ice is produced. Since the water is always sprinkled on the already formed ice, the ice layer does not prevent evaporation of the water and does not create a thermal resistance, so the freezing proceeds. Before the ice grows and fills the gaps between the ice accretion plates, the ice accretion plates are mechanically deformed to release the ice.

The separated ice is crushed and stirred with water stored in the bottom of the container using a stirrer to form an ice / water slurry,
It is extracted from the vacuum ice making container by the slurry discharge device and supplied to the outside of the system as a cold heat source. In order to supplement the extracted ice / water slurry, water is supplied from outside the system to the inside of the vacuum ice making container through a water supply device.

INDUSTRIAL APPLICABILITY The present invention applies a vacuum type ice making system utilizing the latent heat of vaporization of water itself in vacuum to the dynamic type ice making device, instead of the cooling system using a primary refrigerant such as Freon. Since the heat exchange due to the phase change of water on the surface of the generated ice is used without using the heat conduction through the heat transfer tubes for cooling, the heat conduction inside the generated ice during the ice formation process. Is not involved. Therefore, even if the thickness increases as the ice layer grows, the speed of ice making is not affected, and high ice making efficiency can be realized. Also,
Since the generated ice is forcibly released and taken out of the vacuum ice-making container as ice / water slurry, cold heat (ice / water slurry) can be stored in an external atmospheric pressure container. It is possible to increase the capacity of the ice making device without increasing the capacity of the ice making container. Due to the above advantages, the present invention is particularly suitable for use as a large-scale ice making device.
