In addition, the inner roller 240 is coupled to a plurality of positions radially spaced apart from the rotation center of the first holder 220 and the second holder 230 to provide a space through which the yogurt ice cream passes as described above. Form.

On the other hand, the outer roller 250 is preferably such that the outer peripheral surface is arranged so as to be spaced apart from the inner wall of the cooling cylinder 10 by a predetermined interval.

That is, when the outer roller 250 moves while maintaining a constant gap with the inner wall of the cooling cylinder 10, when the ice cream meets the frozen yogurt ice cream is pushed out.

At this time, since the outer roller 250 is rotated while pushing the frozen ice cream, it is possible to minimize the impact of the lactic acid bacteria die by reducing the shock applied to the frozen yogurt ice cream.

On the other hand, the cooling cylinder 10 is installed to surround the inner cylinder 11 and the inner cylinder 11 to cool and stir the yoghurt ice cream stock solution as described above, but in an area in contact with the inner cylinder 11. The space portion 12a is formed to include an outer cylinder 12 through which the refrigerant flows.

In this case, the partition rings 217 and 218 are provided in plural in the longitudinal direction of the inner cylinder 11, and the openings 217a and 218a formed in the partition rings are alternately disposed on the upper side and the lower side of the inner cylinder 11. Can be formed.

In addition, the stirring unit 200 is formed at the rear of the second holder 230, and transfers the yogurt ice cream stirred by the inner roller 240 to the discharge port 14 of the cooling cylinder 10. It is also possible to further include an impeller 260 (see Figs. 3 and 4).

This is the same in the embodiments described later, so duplicate description is omitted.

Hereinafter, with reference to Figure 9 will be described the operating mechanism of the cooling cylinder according to an embodiment of the present invention.

First, in order to mix and supply the ingredients of yogurt ice cream (mixture of milk, lactic acid bacteria material, yogurt, etc.), the stock solution supply unit 20 supplies a hopper 22 and a refrigerant for cooling the yogurt ice cream stock solution formed by mixing the ingredients. And a cooling cylinder 10 for mixing and cooling the yoghurt ice cream stock solution with air, and the like.

The hopper 22 includes a reservoir 21 for storing the material of yoghurt ice cream, a shaft 23 driven to rotate in the reservoir 21, and a stirrer 24 coupled to the shaft 23. . The shaft 22 is connected to the hopper driving motor 25 and driven to rotate. As the shaft 22 rotates, the stirrer 24 rotates to stir the yoghurt ice cream material.

On the other hand, the pulley (P10) installed on one side of the cooling cylinder 10 and the pulley (P30) provided in the motor 30 is interlocked, the rotational force is transmitted from the motor (30) to the cooling cylinder (10) side.

According to the power transmission process, the first and second holders 220 and 230, the inner roller 240, and the outer roller 250 rotate together.

At this time, the inner roller 240 is rotated by the transmitted rotational force to agitate the yoghurt ice cream stock solution inside the cooling cylinder 10, whereby the yogurt ice cream stock solution is mixed with air.

The outer roller 250 rotates but moves along the inner wall of the cooling cylinder 10.

At this time, the outer roller 250 is moved while maintaining a constant gap with the inner wall of the cooling cylinder 10, when it meets the frozen yogurt ice cream will push out the frozen ice cream. At this time, since the outer roller 250 is rotated while pushing the frozen ice cream, it is possible to minimize the impact of the lactic acid bacteria die by reducing the shock applied to the frozen yogurt ice cream.

Thereafter, when the discharge mechanism 60 is operated to open the discharge port 14 of the cooling cylinder 10, the yoghurt ice cream inside the cooling cylinder 10 is discharged toward the discharge port 14, and in the process, the yoghurt ice cream is impeller ( 260 is pressed to the discharge port 14 by the rotation operation

Finally, it is discharged to the outside.

At this time, the air nozzle 130 is exposed after passing through the cooling tube 110 is ejected into the cooling cylinder (100).

By this configuration, since the air is cooled by the refrigerant tube 110 similarly to the second embodiment, the three-dimensional cooling effect inside the cooling cylinder 100 may be further increased.

Otherwise, the description is the same as in the first embodiment, and overlapping description is omitted.
