間に空間１０３が形成されてしまう。However, in the case where the refrigerant pipe 102 is spirally closely wound around the outer wall of the inner cylinder 34 as in the above structure, the inner cylinder 34 and the refrigerant pipe 102 are wound.
It is necessary to completely fill the space 103 between and with the solder, but the filling of the solder cannot be seen from the outside, and the soldering work requires a lot of labor and skill. However, if the refrigerant pipe 102 is not completely fixed, the space 103 is formed between the inner cylinder 34 and the refrigerant pipe 102.

能力が著しく低下する問題があった。Therefore, the inner wall of the inner cylinder 34 is satisfactorily cooled in the portion in contact with the refrigerant vapor 102, but the cooling effect is transmitted to the wall surface of the inner cylinder 34 in the other space 103. Therefore, the heat exchange efficiency decreases. In particular, from the start of ice making, first on the inner wall of the inner cylinder 34, ice starts to grow spirally only in the portion in contact with the refrigerant pipe 102, and then in the other portion, the ice is formed.
Due to the decrease in heat exchange efficiency and the variation in heat transfer, there is a problem that the ice making capacity is significantly decreased.

する。In order to solve such a problem, for example, as disclosed in Japanese Utility Model Publication No. 3-8926 (F25C1 / 14), an outer cylinder is provided around the inner cylinder instead of the refrigerant pipe, and a refrigerant is provided between both cylinders. However, no matter how the refrigerant is dispersed at the upper and lower ends of the outer cylinder, the refrigerant is still above and below. Since it goes straight up between the entrance and exit and rises, the heat exchange efficiency between the evaporating refrigerant and the inner cylinder is significantly reduced.

In FIG. 8, the same symbols as in FIG. 7 are the same. In this case, similarly, the refrigerant pipe 102 is deleted, and a stainless steel outer cylinder 48 is prepared instead. The inner cylinder 34 is concentrically inserted into the outer cylinder 48 with a space therebetween.
Are fixed to the outer wall of the inner cylinder 34 at the upper and lower ends. The outer cylinder 48 is spirally recessed in the direction of the inner cylinder 34 to form a spiral recessed portion 49, and the recessed portion 49 contacts the outer wall of the inner cylinder 34 so that the space between the inner and outer cylinders 34, 48 rises from bottom to top. A crossing spiral evaporation space 108 is formed.

Since the temperature rises, the deterioration of the heat exchange property due to the straight movement of the refrigerant in the vertical direction as described above is eliminated, but the evaporation space 108
The inner wall of the inner cylinder 34 in the portion facing the inner wall is strongly cooled, and the inner wall of the inner cylinder 34 in the portion in contact with the recess 49 is the inner cylinder 34.
Since the cooling is performed via the wall of No. 1, the heat transfer efficiency to the inner cylinder 34 is also low, and there is a problem in that the heat transfer varies and the ice making capacity decreases.

The upper and lower ends of the outer cylinder 27 are fixed to the outer wall of the inner cylinder 26. The heat insulating material 4 is the outer cylinder 27.

The low spiral fins 29 project from the outer wall of the inner cylinder 26 to a substantially middle portion of the evaporation space 28, and the tips of the high spiral fins 31 reach the inner wall of the outer cylinder 27.
The high spiral fins 31 define a vertical spiral passage in the evaporation space 28, and the low spiral fins 29 define the low spiral fins 29 in the evaporation space 28 along the traveling direction of the passage.

The evaporation space 28 spirally rises and evaporates, cools the inner cylinder 26, and exits from the uppermost refrigerant outlet 18. At this time, since the low spiral fins 29 are formed along the traveling direction of the refrigerant, they do not interfere with the circulation of the refrigerant and, on the contrary, have a rectifying action. Since the inner cylinder 26 becomes below freezing due to such cooling, an ice layer grows on the inner wall of the inner cylinder 26, and this ice layer is peeled off by the blade 20 on the outer surface of the auger 1 and transferred to the upper part of the inner cylinder 26 as described above. By pressing with the pressing head 12, thin flaky ice pieces are generated.

Therefore, the inner cylinder 26 is cooled more efficiently than the evaporating refrigerant, and the inner wall of the inner cylinder 26 is strongly cooled thereby, so that an ice layer is quickly formed on the inner wall. Further, since the refrigerant rises in the evaporation space 28 defined by the high spiral fin 31 in a spiral shape, the evaporated refrigerant is spread over substantially the entire outer wall of the inner cylinder 26,
As a result, the inner cylinder 26 is cooled substantially uniformly, and an ice layer is substantially uniformly generated on the inner wall of the inner cylinder 26. As a result, the ice making capacity of the ice making device 25 is significantly improved. In particular,
Since the high and low spiral fins 31 and 29 are formed integrally with the inner cylinder 26, the number of parts does not increase.
