Although not shown, when the operation lever 30 is rotated clockwise to raise the saddle member 11, the switch of the drive motor 19 is automatically turned on when the saddle member 11 reaches a certain position. It has become so.

The above-mentioned surplus container 15 is accommodated in the front of the inside of the base 2, while the cooler 38 for supplying cold air toward the container 15 is arranged behind the inside of the base 2. . still,
In the figure, reference numeral 39 is an operation switch of the cooler 38, and 40 is a thermometer indicating the temperature inside the base 2.

Next, the use state of this device will be described. First, the user opens the opening / closing door 4 and puts a predetermined amount of solid ice cream and desired flavors such as nuts into the container 10 together. Next, when the operation lever 30 is rotated clockwise in FIGS. 2 and 3, the saddle member 11, the ice cream container 10 and the front are moved through the first link 32, the intermediate link 33 and the second link 35. Panel 5 rises. Then, along with this rise, the drive motor 19 is electrically turned on, and the spiral rotor 21 starts to rotate (see FIG. 6). When the fins 23 of the spiral rotating body 21 approach the inner wall of the container 10, the solid ice cream is processed.

The crushing and stirring action will be described in detail with reference to FIGS. 7 and 8. First, the spiral rotator 21 crushes the solid ice cream I in the container 10 from the upper part while gradually biting into the inside thereof, while the crushing blade 25 and the fins 23 are used to crush the solid ice cream I and the nuts N. Partially crushed (No. 7)
Figure).

When the operating lever 30 is further rotated and the spiral rotating body 21 is completely immersed in the container 10, the solid ice cream I and nuts N move downward while being crushed by the fins 23 of the spiral rotating body 21. . During this time, the solid ice cream I is crushed and crushed into a cream, and the nuts N are gradually crushed into fine grains by the fins 23.
It is evenly dispersed in Ice Cream I.

The nuts N that have moved downward as large grains that have not been sufficiently crushed are subjected to a force (symbol F in FIGS. 7 and 8) that causes the container 10 to move upward by the operating lever 30, while the spiral rotor 21 is iced. Since the cream I is to be moved downward, while the creamy ice cream containing the completely granulated nuts N ′ is discharged downward from the mouth,
Instead, it ascends through the notch 24 of the fin 23 without staying at the bottom of the container 10. This reverse movement does not extend above this because the notch 24 is not provided in the uppermost fin 23. Further, the contents in the storage container 10 are covered with the fins 23 on the uppermost stage.

The end edge of each notch 24 is located at the notch edge on the rear side in the downward direction of the spiral, that is, on the left side in FIG. The edge is located slightly higher, the upper surface of the front edge is slightly downward, and the lower surface of the rear edge is slightly upward.
Therefore, as the spiral rotates, the large-sized nuts N ′ are crushed by this edge portion, particularly the rear edge portion while passing through the notch portion 24. Then, while being re-moved downward by the fins 23, some of them are further crushed between the fins 23 and the inner wall of the container 10. Further, since the cutout portion 24 is provided in a straight line in the axial direction of the spiral rotating body 21,
The above-mentioned reverse movement of the large-sized nuts N ′ is smoothly performed with the pressing action of the fins 23 on the ice cream I.

In this way, the hard nuts N are crushed into fine particles while repeatedly rising and descending in the ice cream I, uniformly dispersed in the ice cream ice cream, and discharged from the mouth.

The soft serve ice cream discharged from the mouth portion 13 is received by a desired cup such as a corn cup prepared by the operator of the apparatus below the storage container 10. The remaining soap ice cream that has overflowed from this cup or could not be received falls down and is a removable surplus container 15
Fall inside. The ice cream in the receiving container 15 is constantly cooled by the cooler 38 arranged behind it,
It does not adversely affect the hygiene of the device itself.

Incidentally, in the above-mentioned embodiment, the case where nuts are used as the flavor mixed in the solid ice cream has been described, but in the device according to the present invention, ice is also obtained by the same action when other flavors are used. It can be evenly dispersed in the cream to completely season it.

(Effect) As described above, according to the present invention, the container containing the solid ice cream and various flavors added thereto rises toward the spiral rotating body, and at the time of this rise, the container inside the container The solid spiral ice cream etc. is crushed by rotating the tapered spiral rotor along the inner shape of the solid ice cream so that the solid ice cream etc. is crushed by the wing surface of the fin and the outer end of the fin. It is crushed and discharged smoothly from the bottom of the container to the outside.

The spiral fin of the spiral rotor has notches at each pitch, and the notches are aligned in a straight line parallel to the axis, and the notches are located at the notch edge on the front side in the downward direction of the helix. The solid flavors are crushed by the edges while passing through the notches because they are positioned higher than the notched edges of the ice cream of the ice cream containing the solid flavors from the bottom to the top. The reverse transfer is also carried out smoothly, and finely crushed solid flavors are uniformly dispersed in the soft ice cream to produce a soft ice cream having a full flavor in a short time.
