Description

[Detailed Description of the Invention] The present invention mainly relates to a device for producing frozen desserts such as ice cream and sherbet for home use.

Conventionally, as shown in Figure 1, in a machine for making homemade ice cream, etc., ice B containing salt is placed in an outer container A, and an inner container C is placed in the center, so that the inner container C is buried in the ice. Frozen desserts were produced by putting food and drink into the inner container C and stirring for a long time.

This method generally uses ice cubes several centimeters square, and the temperature of ice cubes with 15% salt added can theoretically drop to -15°C, but the actual ice temperature is about -5°C, and the outer surface of the container Since this is a point contact, the food and drinks in the inner container C cannot be cooled quickly, and therefore it takes a considerable amount of time to make ice cream or the like.

The gist of the present invention is to make the conventional two containers, the inner and the outer, into an integrated, sealed double container, to create a cold storage container with a cold storage agent sealed in the double container and an opening at the top, and to place food and drinks in the cold storage container. As a result, this frozen dessert maker receives heat transfer from the entire surface of the food and drink that is placed therein, and cools the food at a lower temperature than in the past.

The present invention will be described in detail below with reference to the drawings.

FIG. 2 is a longitudinal sectional view of a frozen dessert container according to the invention, which consists of a cold storage container, a lid, and an agitator.

1 is a cold storage container, and a deep-drawn inner layer can 2 made of aluminum alloy
Similarly, the outer layer cans 3 are integrally wrapped around each other at their upper end peripheries.

In this sealed 2-container container, 5 liters of cold storage material are added in advance before wrapping.
is included.

Therefore, the cold storage container 4 has a cylindrical shape with a bottom that is open at the top, and food and drink can be poured into the container from the top opening.

In this case, the upper end of the inner layer can 2 is provided with a wide-mouthed curved surface as shown in FIG. 2, and its outer peripheral edge is fixed to the outer layer can 3 by means such as seaming, and the bottom corner is provided with a wide-mouthed curved surface. It has a rounded taste.

The food and drink can be heat exchanged over the entire surface area by the cold storage body 5 sealed in the hollow formed by the inner and outer layers 2 and 3 through the aluminum alloy plate with good heat conduction.

The 4th part of the edge wrapping is done around the upper edge of the outer layer of the double-sealed container to make it easier to put in food and drink and to prevent it from leaking to the outside, and also to make it easier to put in and take out food by fitting with the lid described later. , and to facilitate operation during use and prevent the contents from scattering.

Reference numeral 6 is a disc-shaped lid made of synthetic resin or the like with good heat insulation properties, and a projection ring 7 is integrally formed near the outer periphery of the lower surface of the lid for removably fitting onto the upper edge of the cold storage container. ing.

Further, a thrust bearing 8 is provided at the center of the lid 6 to support a rotating shaft 10 of a stirrer, which will be described later.

Reference numeral 9 denotes a stirrer, and a rotary shaft 10 has rotating blades 11 attached thereto to stir the food and drink in the cold storage container 1 during use.

In the middle and upper part of the rotating shaft 10, there is a supported seat 12 for a bearing for vertical rotation of the rotating shaft 10, and in the embodiment, the diameter of the rotating shaft is large.

The upper end thereof has a bundle 13, and a handle 14 is rotatably provided upward at the outer end of the bundle.

15 is a cold insulation case, and 16 is a cold insulation material.

When the bottom and outer surfaces of the cold storage container 1 are covered with the cold storage case 15, the thermal efficiency of the frozen dessert maker of the present invention can be further improved.

Next, to explain the cold storage agent, the cold storage agent used in the present invention is a carbonated water-based cold storage agent with organic or inorganic salts added. Cold storage agent can be easily obtained.

Furthermore, in order to adjust the viscosity of the refrigerant, adding an organic thickener can facilitate the work at the time of enclosing the refrigerant.

Finally, to outline the method of using the proposed device, first, the cold storage container 1 is cooled in advance in a freezer, and the cold storage agent is kept in a frozen state, that is,
°C, put the food and drink vlJ17 into the cooled cold storage container 1, fit the lid 6, and rotate the bundle 13 of the stirrer 9 with the handle 14, the food and drink el17 will be stirred. The entire area of the bottom and outer surfaces undergoes heat exchange to obtain frozen desserts in a very short time.

In addition, the trouble of handling ice as in the conventional method is saved, and since the cold storage container 1 is sealed, there is no chance of ice or cold water splashing into the food or drinks as in the conventional method, making it easy to handle and hygienic. Container 1 can be used repeatedly.
