Description

[Detailed Description of the Invention] This invention relates to a frozen dessert maker that can easily produce frozen desserts such as ice cream and sherbet by cooling mainly in a household refrigerator.

As shown in Fig. 1, this type of conventional frozen dessert maker has an outer container A filled with ice B containing salt, and an inner container C inserted in the center so as to be buried in the ice B. Frozen dessert materials such as ice cream materials were put into this inner container C and stirred for a long time using a stirrer to produce frozen desserts such as ice cream.

However, this method generally uses ice cubes several centimeters square, and although the temperature of ice with 15% salt added can theoretically drop to -15°C, the actual temperature of ice only drops to about -5°C. Moreover, since there is point contact between the outer surface of the container and the ice, the frozen dessert ingredients in the inner container C cannot be cooled rapidly. Since there is no stirring, it takes a considerable amount of time to prepare frozen desserts such as ice cream.

This invention was made with the intention of solving the above problem, and its gist is that at least one pair of stirring blades protrudes from the upper and lower diagonal positions of the rotating shaft to a portion that can approach the inside of the container. To provide a frozen dessert making device characterized in that the stirring blade is formed of blades and is provided with a gentle inclination with respect to the rotating shaft, so that frozen dessert ingredients can be uniformly and quickly stirred. This is what I am trying to do.

Embodiments of this invention will be described below with reference to FIGS. 2 to 4.

In the figure, reference numeral 1 denotes a sealed double container, in which a deep-squeezed inner container 2 and an outer container 3 made of, for example, aluminum alloy are spaced apart from each other on the bottom and circumferential surface, and are wrapped around each other at flanges 4, 4. It has a cylindrical shape with a closed bottom.

In this case, the inner container 2 and the outer container 3 are formed by deep drawing an aluminum alloy plate and then applying an anodic oxide film to the entire surface thereof.

In addition, a lid coolant 6 is sealed in a space 5 extending over the bottom and circumferential surfaces formed between the inner and outer containers 2 and 3, leaving a predetermined gap 7 before tightening.

The cold storage agent 6 is made of, for example, water or carbonated water with the necessary amount of organic or inorganic substances such as alcohol, glycol, ethylene glycol, or chloride added, and an organic thickener to achieve the desired viscosity. , its melting temperature is adjusted to a range of -7°C to -17°C.

Reference numeral 8 denotes a ring made of synthetic resin, which is elastically attached to the tightened portion of the sealed double container 1 so that a recess 9 on the inner circumferential surface thereof fits.

The sealed double container 1 configured as described above is formed into a cylindrical shape with an open top and a bottom, and a predetermined gap 11 is provided in an outer container 10 made of synthetic resin and having a cylindrical shape with an open top and a bottom.
A lid 12 is removably fitted into the opening of the outer container 10.

In this case, the double sealed container 1 is supported by support pieces 13.13 protruding from the inner circumferential surface of the bottom of the outer container 10 at appropriate intervals, and the space between the bottom surface and the circumferential surface of the outer container 10 is A gap 11 is formed between.

Further, the lid body 12 is formed of transparent synthetic resin or the like,
An annular protrusion 14 provided near the outer circumferential surface of the lower surface can be detachably engaged with a stepped circumferential groove 15 provided at the opening of the outer container 10.

On the other hand, a bearing 16 is provided at the center of the lid 12 to rotatably support a stirrer 18, which will be described later.

Further, the stirrer 1 is placed in the center of the inner bottom of the sealed double container 1.
A recess 17 is provided for receiving a rotating shaft 19 forming a part of the rotary shaft 8 .

The stirrer 18 has a cross-shaped spline groove 19 a at the upper end.
from the upper and lower diagonal positions of the small diameter portion 19C of the rotating shaft 19, which are cut out from the large diameter portion 19b having is 0.5 to 1 m from the inner peripheral surface of the sealed double container 1.
It consists of at least a pair of substantially rectangular stirring blades 20a and 20b protruding from each other with a gap of m, and a connecting spline shaft 21a that is removably fitted into the spline groove 19a of the rotating shaft 19. A rotating shaft 19 and stirring blades 20 a and 20 b are rotated by a bundle 21 that is entirely formed in a crank shape.

In this case, the stirring blades 20.20 are
As shown in FIG.
The stirring blades 20a are formed parallel to each other with a gentle slope of 0 to 20 degrees, and the upper stirring blades 20a slope downward, and the lower stirring blades 20b conversely slope upward.

By rotating with the rotation of the bundle 21 and the rotating shaft 19, the stirring blade 20a moves the frozen layer of frozen dessert material on the inner surface of the sealed double container 1 downward, and the lower stirring blade 20a moves downward. Conversely, in b, the frozen layer of frozen dessert material is moved upward, so that the upper and lower frozen dessert materials can be uniformly stirred and kneaded sufficiently near the center of the container 1.

The bundle 21 also includes a spline shaft 21 for connection.
It is composed of an L-shaped bundle main body 21b having a lower end at one end, and a knob 21C rotatably attached to the upper part of the other end of the bundle main body 21b. 16, the spline groove 19a of the rotating shaft 19 and the spline shaft 21 of the bundle 21
When the spline shafts 19a and 19a are fitted together, the neck 21d, which extends to the base of the spline shaft 19a, is rotatably supported by the bearing 16.

To manufacture frozen desserts using the frozen dessert maker of this invention configured as described above, first, place a sealed double container 1 in a refrigerator.
is cooled for several hours to freeze the cold storage agent 6 inside.

Next, the sealed double container 1 and the outer container 1 are placed in a predetermined place.
0. Assemble the lid 11 and the stirrer 18, and put the frozen dessert ingredients into the sealed double container 1.

At this time, the frozen dessert material becomes a thin layer and freezes inside the sealed double container 1, so the stirring blades 20a and 2 of the stirrer 18
By stirring uniformly near the center of the container 1 as described above with 0 b, air will be mixed into the frozen dessert material as fine bubbles, making the whole product soft. be.

In the above embodiment, a case is shown in which there is a pair of upper and lower stirring blades, but it is sufficient that there is at least one pair of upper and lower stirring blades, and the number of stirring blades can be increased as necessary.

Further, although the case where the container into which the frozen dessert material is put is a sealed double container containing a cold storage agent is shown, it does not necessarily have to be a sealed double container, and may be an ordinary cylindrical container with a bottom.

As explained above, according to the frozen dessert maker of this invention, the stirring blade is formed of at least a pair of substantially rectangular blades that protrude from the upper and lower diagonal positions of the rotating shaft to the hanging portion close to the inside of the container, and The stirring blades are parallel to the rotating shaft with a gentle inclination of about 10 to 20 degrees, so the lower blades move upward and the upper blades move the frozen dessert ingredients put into the container upward. In order to move the frozen dessert material downward, the upper and lower layers of the frozen dessert material are rotated near the center of the container so that they are exchanged, so that the frozen dessert material can be mixed uniformly and with fine air bubbles included in the frozen dessert material. You can get a frozen dessert with a soft texture.

Furthermore, since a pair of approximately square stirring blades are protruded at diagonal positions, the frozen dessert can be efficiently obtained even in a deep container, and the stirring blades are durable and easy to manufacture due to their simple shape.

Moreover, since the bundle and the rotating shaft are detachable, it is easy to take out and wash frozen desserts, and the product is hygienic, making it extremely useful.
