Description

[Detailed description of the invention] [Industrial application field] This invention is a frozen dessert manufacturing device that can take out frozen desserts such as ice cream and sherbet produced in a cold storage container from the bottom surface, and more specifically, a rotating member. The present invention relates to a support member that supports a formed screw for extruding frozen desserts.

[Prior Art] In the previously filed Utility Application No. 10836/1983, the present applicant proposed that in a cold storage container filled with a cold storage agent,
With the rotation of a rotating member having a screw that rotates within a support hole of a support member that is inserted into a through hole formed in a through hole formed in the bottom surface of the rotary member that rotates along the inner peripheral surface of the rotary member, the inside of the cool storage container is heated. We have proposed a frozen dessert manufacturing device in which the frozen dessert material is stirred while being cooled by the blades to produce frozen desserts, and then the frozen desserts introduced into the support holes of the support member are extruded as the screw rotates.

[Problems to be solved by the invention] However, if the support member into which the screw is inserted is made of a metal material with high thermal conductivity, it is possible that the screw may be inserted into the support hole of the support member when manufacturing or taking out the frozen dessert. Frozen dessert ingredients and frozen desserts were easy to freeze. For this reason, high rotational resistance acts on the screw, and it is necessary to use a high-torque drive member for the rotating member. As a result, there are problems in that the device becomes larger and heavier, and costs increase.

[Purpose of the invention] In view of the above-mentioned conventional drawbacks, the purpose of the invention is to
To provide a frozen dessert manufacturing device that can prevent frozen desserts flowing into a support hole from freezing and reduce the rotational resistance of a rotating member, and can reduce the size, weight, and cost of the device. be.

[Means for Solving the Problem] Therefore, in the present invention, a support member having a support hole is inserted into an opening formed in the bottom surface, and a support member having a support hole is inserted into the inner surface of the cold storage container in which a cold storage agent is sealed. A frozen dessert manufacturing apparatus that manufactures frozen desserts by rotating a rotating member having a screw rotatably supported within a support hole of the supporting member and a screw that rotates along the support member in a predetermined direction. The frozen dessert manufacturing apparatus is configured because the supporting member rotatably supported is formed of a heat insulating member having low thermal conductivity.

[Operation of the device] Since the present invention is configured as described above, the frozen dessert material flowing into the support hole of the support member that rotatably supports the screw of the rotating member during the production of frozen desserts is not frozen by the cold storage agent. Prevented. This makes it possible to reduce the rotational resistance of the screw during production of frozen desserts, and to produce frozen desserts by rotating the rotating member with low torque.

At this time, the frozen dessert material is attached to the inner circumferential surface of the inner container 26 at a required thickness by the third blade 31f, thereby promoting the cooling effect, and the attached frozen dessert material is
It is scraped off by the blade 31d. Further, the frozen dessert material attached to the bottom surface of the inner container 26 is removed by the second blade 3.
It is scraped off by 1e. Note that during the scraping action by the second blade 31e, the second blade 31e
Since the uneven portion 31g is formed on the lower surface of e,
It is possible to reduce the rotational resistance of the rotating member 31, and avoid the concentrated action of the frozen dessert material on the second blade 31e. The frozen dessert material gathered on the second blade 31e side by the above action is moved to the center by the feed screw 61 that advances toward the shaft portion 31a side, and is then moved to the center of the cold storage container 25.
Convection occurs within the interior. As a result, the frozen dessert material is cooled while being stirred and kneaded almost uniformly.

During production of the frozen dessert, the frozen dessert material that has flowed into the support hole 33d of the cylinder 33 is insulated by the cylinder 33, so that it is prevented from freezing inside the support hole 33d. This prevents the rotational resistance of the screw 31b from increasing, and allows the rotating member 31 to be rotated with low torque.

After the frozen dessert material is kneaded while being cooled to the required hardness, the slide plate 53 is moved to form the hole 5.
3b and the through hole 51a of the holder 51 are brought into communication, the frozen dessert produced by the above action is gathered to the second blade 31e side by the scraping action by the first and second blades 31d and 31e. , is introduced into the cylinder 33 as the screw 61 rotates, and then is discharged to the outside as the screw 31b rotates.

As described above, in this embodiment, the cylinder 33 that rotatably supports the screw 31b for pushing out the manufactured frozen dessert is made of synthetic resin with low thermal conductivity.
The frozen dessert material flowing into the support hole 33d is prevented from freezing. As a result, it is possible to reduce the rotational resistance of the screw 31b within the cylinder 33, and it is possible to manufacture frozen desserts using the low-torque electric motor 17, making it possible to reduce the size, weight, and cost of the device. It is possible.

In the above explanation, the entire cylinder 33 is made of synthetic resin, but as shown in FIG.
The support member inner cylinder 81a that rotatably supports the support member 1b is formed of a metal material with high wear resistance, and the outer peripheral surface of the support member inner cylinder 81a is coated with a synthetic resin portion 81b having a heat insulating property with low thermal conductivity. to form a cylinder 81, and the cylinder 8 as a whole.
It may be one that reduces the thermal conductivity of No. 1 and improves durability.
