Abstract

PURPOSE:To evenly carry out cooling of a frozen food material by synergistic action of scraping off and stirring action with scraping pieces and mixing action with stirring pieces by forming the plural stirring pieces separately from the scraping pieces rotating in the vicinity of a cold reserving vessel in a stirring unit rotating in the cold reserving vessel. CONSTITUTION:A cooling material on the side close to a cold reserving vessel 2 in a frozen food material is stirred so as to be scraped from the aforementioned cold reserving vessel with scraping pieces 13 and mixed with the frozen food material on the inside. Stirring pieces 14 promote the aforementioned mixing action to perform overall cooling without unevenness. Furthermore, if the stirring pieces 14 of a stirring unit 11 are constructed from those having a helix angle advancing in the rotative direction and those having a helix retreating in the rotative direction in combination, mixability of the frozen food material is further improved.

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is a device for producing frozen desserts such as ice cream and sherbet used in general households.
In particular, it relates to the structure of the stirring body.

0002

2. Description of the Related Art Conventionally, in this type of frozen dessert manufacturing apparatus, frozen dessert ingredients cooled in a cold storage container are stirred by a stirrer. The stirring body is equipped with a scraping piece that rotates close to the cold storage container, and stirs the cooled frozen dessert material on the side closer to the cold storage container by scraping it from the cold storage container,
It was made to mix with the frozen dessert ingredients inside.

0003

[Problem to be solved by the invention] However, with such a structure, mixing and stirring of the entire frozen dessert ingredients inevitably becomes difficult, which causes uneven cooling temperature distribution, making it difficult to make frozen desserts successfully. There wasn't.

[0004] The present invention solves these conventional problems, and aims to improve the mixing and stirring characteristics of the entire frozen dessert material, and to quickly produce delicious frozen desserts such as ice cream.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention includes an exterior body, a cold storage container that is removably housed in the exterior body and filled with a cold storage agent, and an upper opening of the exterior body. It is equipped with a cover that can be opened and closed freely, a stirring body that stirs the frozen dessert material cooled in the cold storage container, and a driving body for the stirring body, and the stirring body has a scraping piece that rotates close to the cold storage container. and formed a plurality of stirring pieces.

[0006] The stirring pieces of the stirring body are a combination of those having a helix angle that advances in the direction of rotation and those having a helix angle that recedes in the direction of rotation.

[0007]

[Function] According to the configuration of the frozen dessert manufacturing apparatus of the present invention, among the frozen dessert materials, the cooling material on the side closer to the cold storage container is scraped off from the cold storage container by the scraping piece and stirred, and the frozen dessert inside is stirred. Mix with the ingredients. The stirring piece also promotes this mixing action and provides uniform overall cooling.

Furthermore, if the stirring pieces of the stirring body are configured by combining one with a helix angle that advances with respect to the rotation direction and one with a helix angle that recedes with respect to the rotation direction, the frozen dessert material can be further improved. improves the mixability of

In other words, the stirring piece having a helix angle that moves forward with respect to the rotation direction moves the frozen dessert material toward the outer periphery, and the stirring piece that has a helix angle that recedes with respect to the rotation direction moves the frozen dessert material toward the inner periphery. let Such opposing material movements thus ensure mixing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 1 to 3, an exterior body 1 employing a double peripheral wall structure has a cylindrical shape with an open top and a bottom,
A cold storage container 2 is stored inside the container so as to be freely accessible.

This cold storage container 2 has a cold storage agent 5 between an outer case 3 and an inner case 4 made of a thermally conductive material such as aluminum.
This is a well-known structure in which the tube is filled with a cylindrical tube, and its shape is set to be a bottomed cylinder with an opening at the top. The open ends of the cases 3 and 4 are joined together by means such as caulking, and a ring 6 made of synthetic resin is further placed over the joined portion.

A lid 7 made of a transparent material that opens and closes the upper opening of the exterior body 1 is removably connected to the exterior body 1 using a bayonet mechanism, and has a material input port 8 formed in a part thereof. be. Further, a driving body 9 is provided in an L-shape across the diametrical direction of the upper surface of the lid 7 and the longitudinal direction of the outer circumference.

The drive body 9 includes a motor and a speed reduction mechanism, and has a rotation output section 10 corresponding to the center of the lid 7.

Reference numeral 11 denotes an agitator having a shaft 12 removably attached to the rotational output section 10 of the drive body 9, and is a generally mountain-shaped agitator that rotates close to the inner peripheral surface and inner bottom surface of the cold storage container 2. It has a scraping piece 13 and a pair of stirring pieces 14 erected on a predetermined inner peripheral side of the scraping piece 13.

In the above configuration, for example, when making ice cream, the cold storage container 2, which has been cooled in advance in a refrigerator, is set inside the exterior body 1, and the lid 7, in which the agitator 11 is set, is placed above it. Close the opening. Next, the egg yolk,
A so-called ice cream material made by dissolving fresh cream, sugar, etc. in milk is charged into a stirring chamber 15 in a cold storage container 2 through a material input port 8.

[0016] When the driving body 9 is energized, the ice cream material is stirred and cooled by the stirring body 11.
After a predetermined period of time, the ice cream is completely frozen.

In the above ice cream manufacturing process, the scraping piece 13 of the stirring body 11 scrapes and stirs the ice cream material on the side closer to the cold storage container 2, and mixes it with the ice cream material inside. In addition, the stirring piece 14 stirs the ice cream material in the inner circumference of the stirring chamber 15 to promote the above-mentioned mixing action and achieve uniform cooling as a whole.

By the way, one of the pair of stirring pieces 14 has a helix angle that moves forward with respect to the rotation direction, and the other has a twist angle that moves backward with respect to the rotation direction. Therefore, the stirring piece 14 having a helix angle that advances with respect to the rotation direction moves the ice cream material toward the outer circumference, and the stirring piece 14 having a twist angle that recedes with respect to the rotation direction moves the ice cream material toward the inner circumference. move it.

[0019] Such contradictory movement of materials activates the stirring within the stirring chamber 15, and as a result, the overall mixing is further promoted.

[0020]

Effects of the Invention As described above, in the present invention, a plurality of stirring pieces are formed on the stirring body that rotates within the cold storage container, in addition to the scraping piece that rotates close to the cold storage container. The frozen dessert ingredients are evenly cooled by the synergistic effect of the scraping and stirring action of the pieces and the mixing action of the stirring pieces.
You can quickly make delicious frozen desserts with a pleasant texture.

[0021] Furthermore, if the stirring pieces of the stirring body are configured by combining one having a helix angle that advances with respect to the rotation direction and one having a helix angle that recedes with respect to the rotation direction,
This has excellent effects such as even better mixing of frozen dessert ingredients.
