Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for producing frozen desserts such as sherbet and ice cream.

[0002]

2. Description of the Related Art Ice confection (also called ice confection) refers to food such as sorbet and ice cream. In the case of sorbet, water is added to fruit juice, and a flavoring agent or the like is added thereto and frozen while stirring. For ice cream, cream (substitute milk, condensed milk, powdered milk, etc. as a substitute), chicken egg,
Manufactured by freezing the raw materials that add flavors, etc. to sugar and stickies. Stirring is an operation for mixing air into the material being cooled, and if this is sufficient, a very finely textured frozen dessert can be produced.

From the past, ice desserts have been eaten in a large amount, and the production amount thereof is also very large. These are now generally manufactured in confectionery factories and, of course, automated by large equipment. This is stored in a small container and sold at retail stores.

[0004] In addition, frozen desserts can be basically manufactured by a home freezer or the like, and can be manufactured by freezing the above materials with a freezer or the like. Therefore, frozen dessert materials that can be manufactured relatively easily at home and dedicated equipment therefor are also sold.

However, although there are some kinds of products produced in a factory, they are not one-piece production but uniform, and they do not meet the individual demands one after another. This is especially true in recent times when a large number of small-lot varieties are required. That is, even if the consumer does not sell the sherbet he wants to eat at the frozen dessert store, or wants to eat a special fruit sherbet or a special combination sherbet, such an order cannot be made. , There is no choice but to choose from products from the factory. With this, it is difficult to expect an increase in demand for sherbet.

[0006] In addition, since it is possible to select materials according to one's own preference in manufacturing at home, there is no problem in this respect, but it is fundamentally impossible to produce products with excellent smoothness and texture that are important in frozen desserts. There is a problem. It is difficult for homes to do the work of maximizing the smoothness and texture, and in the end, the fact that household frozen dessert making machines simply cannot satisfy the curiosity has been overcome. Of course, it may be possible to obtain good quality ice cream or sorbet if a person who has gained experience and knows how to do it at home also takes sufficient time and effort, but in special cases it is not so. It is rarely done and is not everyday.

Therefore, as a frozen dessert manufacturing apparatus that can be manufactured and sold on the spot according to individual tastes, a refrigerator is provided, and the frozen dessert material is placed on a cooling plate cooled by this and stirred. There is something called a frozen dessert. In such a conventional frozen dessert manufacturing apparatus, a metal plate having a high thermal conductivity is used as a cooling tray, and a refrigerant circulation pipe leading to a refrigerator is arranged immediately below the cooling tray. It seems that this has solved the problems described above.

[0008]

However, in the case of such a structure, it is difficult to say that the cooling effect is sufficient because the contact portion between the pipe and the cooling dish is small and the amount of cold air that is dissipated is large. In particular, the pipe has a circular cross section (mostly circular)
In the case of, the cooling tray and the pipe were in contact with each other only by a wire, so that the efficiency was very poor.

Further, the poor cooling efficiency means that the output of the refrigerator needs to be increased, resulting in an increase in size of the device and an increase in cost. And 2 to the compressor motor to get high output
There is also a problem that the installation place is extremely limited because the one for 00V must be adopted.

[0010]

Therefore, the present inventor has finally completed the device of the present invention as a result of earnest research in view of the above points, and is characterized in that the ice confectionery material is a ball on a cooling dish. Is a device for obtaining a frozen dessert by cooling the material while stirring it, and the cooling dish is an integrated body of two-layer metal plate-shaped objects, and these two layers are opposed to each other. A groove is formed on one or both of the surfaces to be formed, and a groove hole formed by being integrated and included is used as a refrigerant circulation path.

The term "ice dessert material" as used herein may be not only a commonly used raw material for producing ice desserts such as ice cream powder, cream, fruit juice and water, but also grains, vegetables or the like. Is not limited to
Anything can be used as long as it can be a frozen dessert.

The "cooling dish" is a main part having the features of the present invention. For cooling, a pipe or the like is not brought into contact with the cooling dish, and a continuous "hole" is provided inside the dish while being bent. It is used as a refrigerant circulation path. Since the hole functions as a circulation path for the refrigerant, the hole naturally does not communicate with the outside except the inlet and the outlet, and is entirely contained within the thickness of the cooling dish. The cooling pan is made of metal, but the specific material is not particularly limited. Stainless steel is the most suitable in the sense of high corrosion resistance, copper in the sense of high thermal conductivity, aluminum in the sense of easy processing, and iron in the sense of cheapness, of course. Of course, other metals may be used.
Further, for example, when iron is used, the surface of which is subjected to anticorrosion treatment (plating, application of antirust paint, etc.) is also included in the concept of "made of metal".

This hole is formed by engraving a groove on either or both of the facing surfaces of the cooling dish having a two-layer structure, and then integrally forming these grooves. Therefore, this hole is referred to as a "groove hole".
I will say. Further, the "engraving" referred to here is not limited to the work of actually cutting a flat plate, but also includes a groove formed when a groove is formed by injection molding of aluminum, for example.

The "ball" is a portion into which a frozen dessert material such as fruit juice is put, and is provided so as to be in close contact with the upper surface of the cooling dish. After the frozen dessert is manufactured, this ball should be easy to remove so that it can be easily washed, but it also means that the last frozen dessert material left over is not mixed with the next frozen dessert material for hygiene. Is also preferable. It can be said that the material of the ball is a metal having high thermal conductivity, and stainless steel which is not easily corroded is particularly preferable.

In the actual production of the frozen dessert, the frozen dessert material may be manually stirred, but it may be automated. This is because the most troublesome and important work for producing a good-quality frozen dessert is the work of stirring the ingredients. Therefore, it is preferable that the device has a stirring blade that is rotated by a driving machine. The structure is preferably such that the stirring rotation speed can be freely adjusted and the amount of air to be mixed is also adjustable. The stirrer is composed of a motor and a stirrer, and the stirrer usually has a structure like a vane or an egg whisk. In addition, the shape of the ball is a rotating body,
It is considered that if the stirrer is shaped so as to follow the rotating body, unevenness in freezing of the material is unlikely to occur and it is preferable. In that case, for example, two stirring blades are provided from the rotating shaft, one side of which is a blade for cutting off the frozen portion, and the other side is a blade for pressing the cut-off raw material again to the bottom of the concave portion, which is the freezing surface. If it is, the manufacturing time is shortened, which is more preferable.

The refrigerator used in the apparatus of the present invention may be a normal refrigerator, or may be of the type that deprives the heat of vaporization by expanding the refrigerant. As a method for cooling the cooling pan, a conventional method of circulating a refrigerant from a refrigerator is adopted, and in the case of the device of the present invention, the cooling efficiency is high. There was no problem in adopting it.

In addition to the above essential components, various equipment can be added to the main body. For example, a container for storing fruit juice, flavors, various essences, sweeteners, a container for mixing, and the like. In addition, to make it easy to move, it is convenient to open at fairs, pedestrian streets, etc., and to change the installation position even when installed in a store, so that you can easily move it. You can

After the frozen dessert is completed, it is necessary to wash the balls. However, a heater is attached to the lower part of the cooling dish so that the frozen residue or the balls themselves can be easily removed or removed. It is convenient. Further, if this heater is used for fine adjustment of the cooling temperature of the cooling tray, a wider variety of frozen desserts can be obtained.

The method of using the device of the present invention will be briefly described. First, the refrigerator is operated to cool the cooling pan. The cooling temperature is preferably about -20 to -60 ° C.
In that case, if the above-mentioned heater is added, a wide range of temperatures can be set, which is effective. Next, materials (ice cream powder, fruit juice, fragrances, etc.) according to the tastes of consumers.
Mix and adjust. It is put into a bowl on a cooling dish, and stirring is started manually or by a stirrer. If you cover the ball with a transparent cover (lid), the material will scatter.
It is suitable for preventing waste of energy. When added, the material is rapidly cooled and frozen, but because it is agitated, it mixes with air and becomes a mixture of fine ice and air. This completes the frozen dessert, which can be put in a separate container and provided to consumers.

In order to obtain a higher quality frozen dessert, a heating step may be added during the cooling of the raw materials and the cooling and heating may be repeated. By doing this, the principle itself that will give a frozen dessert with a good texture is unknown, but if the raw material is rapidly frozen, the frozen particles tend to become large and the texture becomes rough, so the heating process It is conceivable that the reason is that the freezing rate can be reduced by adding the above, and the manufacturing time can be shortened as compared with the case of gradually freezing. In addition, such a heating process,
It is also possible to reverse the direction of circulating the refrigerant in the refrigerator (heat pump type).
