Description

Manufacturing method of decorative ice and its manufacturing apparatus {METHOD AND APPARATUS FOR ICE FOR DECORATION}

The present invention relates to a method of manufacturing decorative ice and its apparatus, and more particularly, to a method of manufacturing decorative ice and apparatus for producing ice by circulating water in a forming mold disposed in a liquid that does not freeze.

In general, decorative ice mainly used for a banquet hall or an event hall is divided into decorative ice produced by hand and decorative ice produced using a molding frame.

The decorative ice produced by the above-mentioned manual work is a sculpted ice cube by a professional sculptor, which is not only dangerous, but also takes a lot of time to produce the decorative ice, so that only small quantities can be produced on demand. The price was very high.

In order to solve the problem of the manufacturing of decorative ice according to such a manual work, a decorative ice manufacturing method using a molding frame has been proposed, such as "Republic of Korea Patent No. 0537157", "Republic of Korea Patent No. 0553340", "JP-A-2002-200898" and "JP-A-2883315" are mentioned.

First, "Korean Patent No. 0537157" refers to a left opening surface of a transparent left ice container having one side opened to contain contents and a right opening surface of a transparent right ice container having one side opened to contain the contents. It proposes a packaging container made of ice that is made integrally attached to each other, "Korea Patent No. 0553340" after placing the molding frame for forming the ice piece to be placed in a freezing tank containing the cooling solution at a predetermined height, Pour water into the mold, put the injection pipe connected to the air pump in the water of the center of the mold, and operate the air pump to inject air into the water through the injection tube, and when an ice film having a predetermined thickness is formed in the mold Put the decorations to be put inside the ice cubes into the water in the mold and make them adhere to the ice film. When water is frozen to the predetermined thickness from the inner surface of the mold to form an ice operating body having a residual groove therein, the mold is removed from the freezing tank to separate the ice sculpture body from the mold, and then the residual formed inside the ice sculpture body. A method and a mold for forming ice cubes by blocking grooves are proposed, and "JP-A-2002-200898" discloses that a dried plant such as pressed is squeezed between a base body and a cover body made of ice. The present invention proposes a display body, and finally, "Japanese Patent No. 2883315" proposes a method of manufacturing a decorative ice flower by standing flowers in an inner space of a pillar of transparent ice and finishing the lower portion of the pillar.

By the way, the above-described conventional manufacturing method of decorative ice has the advantage of mass production of ice sculptures having a variety of shapes, "Korean Patent No. 0537157" and "Japan Patent No. 2883315" to decorate the interior of the ice It is a structure to receive, and "JP 2002-200898" is a structure that narrows the decoration, so that the three-dimensional and aesthetic sense of the decorative ice is not only reduced, but also the transparency of the decorative ice produced because the space is present inside the decorative ice. There was a problem that was not clear.

And "Korean Patent No. 0553340" when the ice sculpture body having the residual groove is formed to remove the mold from the freezing tank, and then separated, and the ice cube support plate to block the residual grooves to form the ice sculpture, so the work process It is cumbersome and complicated, and as a result, the residual grooves exist inside the decorative ice.

Therefore, there is an urgent need to develop a method of manufacturing decorative ice and a manufacturing apparatus thereof, in which the manufacturing process of the decorative ice is simple and there is no space in the decorative ice.

The present invention has been made to solve the conventional problems as described above, an object of the present invention is to provide a manufacturing method of decorative ice for producing ice by circulating water in a molding mold disposed in a freezing liquid.

Still another object of the present invention is to provide an apparatus for producing decorative ice, wherein water is manufactured by circulating water in a forming mold disposed in a liquid which is not frozen.

In order to achieve the object of the present invention as described above, the present invention,

In the manufacturing method of decorative ice,

Provided is a method of producing decorative ice, which produces decorative ice while circulating water in a molding mold disposed in a liquid which does not freeze even at a temperature below freezing point.

In addition, the present invention, in order to achieve to another object of the present invention,

In the manufacturing apparatus of decorative ice,

The manufacturing apparatus of the decorative ice,

An ice making unit having a liquid which does not freeze even at a temperature below freezing point;

A molded part disposed in the liquid which does not freeze; And

It provides a manufacturing apparatus for decorative ice comprising a; water circulation portion for circulating supplying water to the molding portion disposed in the ice making unit to produce decorative ice.

As described above, according to the manufacturing method and the manufacturing apparatus of the decorative ice according to the present invention, since the ice can be manufactured by circulating water in the molding mold disposed in the non-freezing liquid working process according to the manufacturing of decorative ice There is an advantage in obtaining this simple, clear and transparent decorative ice.

FIG. 2 is an exploded perspective view showing the molding part shown in FIG. 1 separately;
3 is an enlarged perspective view of the holding means shown in FIG.
FIG. 4 is an exploded perspective view illustrating an exploded view of the gripping means shown in FIG. 3.

Hereinafter, with reference to the accompanying drawings will be described a manufacturing method and a manufacturing apparatus of the decorative ice according to an embodiment of the present invention.

First, the manufacturing method of the decorative ice according to the present invention, the forming mold 138 to obtain the decorative ice (D), the liquid (C) that does not freeze the produced mold 138 even at a temperature below freezing point After placing in the furnace, water is circulated in the mold 138 to prepare decorative ice (D).

Circulating the water in the mold 138 is to increase the transparency of the decorative ice (D) to be manufactured, the decorative ice (D) is formed from the wall of the mold 138 in contact with the liquid (C) that does not freeze 138 is formed toward the center side. The mold 138 may include one or two or more selected from various flowers, fruits, or other decorations.

On the other hand, the liquid C which is not frozen is prepared by mixing a conventional antifreeze with water, and is cooled by the operation of the normal refrigeration cycle 116. Table 1 shows the mixing ratio of water and antifreeze.

water antifreeze Mixing ratio 5 to 6 4 to 5

Table 1. Mixing ratio of water and antifreeze

As shown in Table 1 , the liquid (C) that does not freeze is mixed in a water: antifreeze ratio of 5-6: 4-5. If the ratio of the antifreeze is less than 4, the liquid (C) that does not freeze is frozen, and if the ratio of the antifreeze is mixed more than 5, there is a problem that a large initial cost occurs.

The liquid C that is not frozen is cooled to a temperature of −4 ° C. to −15 ° C., but in order to obtain transparent and clear decorative ice D, cooling is preferably performed sequentially from −4 ° C. to −15 ° C.

That is, when the temperature of the water circulated by the liquid (C) that does not freeze is 0 ℃, an ice film is formed on the wall of the molding die 138. When the ice film is formed, the liquid (C) that does not freeze for 4 to 5 hours The temperature is kept at a temperature of -4 ° C to -6 ° C, followed by another temperature of -7 ° C to -9 ° C for 5-6 hours, and finally -11 ° C to -15 ° C for 10 to 12 hours. It is maintained at the temperature of to prepare a decorative ice (D). Maintaining a constant temperature within a certain time as described above, if the start of manufacturing the decorative ice (D) at a temperature that is too high from the beginning, for example, -10 ℃ or more, there is a problem that a crack occurs in the resulting ice When the manufacturing of the decorative ice (D) is started at a temperature that is too low, for example, less than -4 ° C, there is a problem that the working time becomes long.
