BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the drawings (FIGS. 1 to 4), taking the case of producing soft serve as an example. FIG. 1 is a perspective view showing the whole apparatus for producing a soft ice cream of the first invention according to the present invention. The apparatus connects the bottom of a plurality of regenerators 1 to the rotation shaft of a final connecting gear in a drive case 2 containing a drive motor, a group of gears, and the like. 3 and the upper part of the shaft of the stirring blade 3 is fixed by the cover 4. By injecting different materials into the plurality of cold storage containers 1, different types of soft ice cream can be manufactured at one time.

FIG. 2 is a side sectional view of the soft ice cream manufacturing apparatus according to the present invention. In the cold storage container 1, a cold storage agent 7 is sealed in the gap between the inner container 5 and the outer container 6, and the inner container 5 and the outer container 6 are welded and joined at their respective mouths so that the cold storage agent 7 does not leak. . The cold storage container 1 has a size that can accommodate the amount of one soft serve (about 150 ml), and can be used as tableware after the soft serve is manufactured. In addition,
It is conceivable to provide the cold storage container 1 with stable legs for use as tableware. Examples of the regenerator 7 include those containing propylene glycol, potassium bicarbonate, etc., with the balance being water. Since the cold storage container 1 can be detached from the rotation shaft of the final connecting gear in the drive case 2, it is detached before the soft ice cream production and frozen in a freezer or the like in advance (−
20 ° C to -18 ° C). Thereby, a low temperature can be secured at the time of soft ice cream production. In order to efficiently cool the material of the soft ice cream poured into the cold storage container 1 and to prevent the cold storage agent 7 from absorbing heat from the outside of the cold storage container 1 as much as possible, the inner container 5 is made of a heat conductive material such as stainless steel or aluminum. Outer container 6
Is formed of a material having low thermal conductivity such as a synthetic resin.

The drive case 2 rotates a drive motor 8 as shown in FIG.
Rotational force is transmitted by the first gear 11 and the second gear 12, and each regenerator 1 is rotated by the transmission of the rotation shaft 13 of the second gear. As a transmission device for transmitting the rotational force of the drive motor 8 to each cold storage container 1, in addition to the above, a configuration in which a belt or a chain is wound around a rotary shaft of the drive motor and a rotary shaft connected to each cold storage container is also considered. Can be In order to prevent idling, the bottom of the regenerator 1 and the rotating shaft 13 of the second gear are connected to each other, instead of making the tip of the rotating shaft 13 of the second gear into a cylindrical shape, the shape of the head of the driver is used. And a concave portion provided at the bottom of the cold storage container 1 is connected to the tip of the rotating shaft 13 of the second gear.

As long as the stirring blade 3 can stir the material of the soft ice cream, a screw, a spiral coil or the like may be used in addition to a blade having several blades attached to a rod as shown in FIG.

The cover 4 is formed of a heat insulator, and after the frozen regenerator 1 is connected to the rotating shaft 13 of the second gear and the stirring blade 3 is inserted into the regenerator 1, the cover 4 is moved to the drive case 2. Take a configuration to cover. It is conceivable to use a transparent plastic for the cover 4 in order to visually confirm the completion of the soft serve. The cover 4 has, on the ceiling, insertion holes 14 for fixing the stirring blades 3 at the upper portion of the shaft and a material injection port 15 for soft cream, the number of which is equal to the number of regenerators. Note that the stirring blade 3 may not be detached from the cover 4. In addition, before the cover 4 is covered, the soft-cream material can be injected into each regenerator 1, so that the soft-cream material injection port 15 need not be provided.

After inserting the upper part of the shaft of the stirring blade 3 into the insertion hole 14 of the cover 4 and fixing the same, the material of the soft cream is injected from the material injection port 15, and the drive motor 8 is rotated so that the frozen regenerator is frozen. 1 for a predetermined time, 45-60r
When rotated at a stirring speed of pm, a soft ice cream is completed. In the case where a 500 ml material is made into a soft cream by rotating stirring blades in a single large container, it takes 15 minutes to complete, whereas a 150 ml material is completed in about 5 minutes. Are rotated together to produce a soft ice cream, so that the same amount of ice cream can be produced in a shorter time. When the temperature of the cold storage container 1 frozen as described above rises and the soft ice cream is cooled to −6 ° C. to −5 ° C., the soft ice cream is completed, so the cold storage container 1 or the stirring blade 3 You can attach a temperature sensor to check the completion of the soft serve. It is desirable that the attachment portion of the temperature sensor is hardly affected by rotation, and there is a method of embedding or bonding the inner portion of the cool storage container 1 or the shaft of the stirring blade 3. After completion of the soft ice cream, the drive motor 8 is stopped, and the cover 4, the stirring blade 3, and the cold storage container 1 are removed in this order, and the cold storage container 2 can be used as a table as it is for a table.

In the above-described embodiment, the regenerator is rotated to fix the stirring blades. However, as shown in FIGS. 3 and 4, a plurality of regenerators 1 are fixed on a manufacturing case 16 for storage. A configuration of a manufacturing apparatus in which a drive motor 8 for rotating the stirring blade 3 inserted into each regenerator 1 and a drive case 2 in which a transmission device such as a gear group is disposed is also conceivable. FIG. 3 is a perspective view showing the entire soft ice cream manufacturing apparatus of the second invention according to the present invention. FIG. 4 is a side sectional view of the same device. The structure of the cold storage container 1 and the drive case 2 is the same as that of FIG. 2. In this device, the bottom of the cold storage container 1 is fixed by the manufacturing case 16, and the stirring blades 3 are inserted into the plural cold storage containers 1 respectively. The rotation shaft of the stirring blade 3 is connected to the rotation shaft of the final connection gear in the drive case 2 containing the drive motor 8 and the gear group. It is conceivable to use a transparent plastic for the manufacturing case 16 in order to visually confirm the completion of the soft serve.

[0015] Further, both the plurality of regenerators and the stirring blades inserted into each double-walled container are connected to the rotation shaft of the final connection gear in the drive case containing a drive motor, gears and the like. There is also a configuration that matches. Note that the number of drive motors is not necessarily one.

As described above, according to the embodiment of the present invention, by using a plurality of cold storage containers, different kinds of soft ice cream can be manufactured in a short time at a time, and from the container of the manufacturing apparatus. The trouble of distributing to another container can be saved.

[0017]

As described above, according to the present invention, different kinds of frozen desserts can be manufactured at once in a short time.
