Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing frozen ice sculptures that are used at parties and can be placed on a table to create a cool feeling, and an apparatus directly used for carrying out the method.

0002

[Prior Art] Conventionally, this type of technique is a skill possessed by trained chefs, and involves bringing a block of ice near the party venue and shaving it with a chisel. It was getting worse. This technique was so specialized that competitions were held, and it was not common.

0003

[Problems to be Solved by the Invention] Because such special skills are required, ice carving cannot be easily used. As a result, it became rare and valuable, and combined with its easy melting properties, there were no commercially available products available through the distribution system. If there is a dedicated refrigerator for this purpose, it can also be used in general households. In addition, in the conventional method, some parts are wasted due to scraping, but if this can be eliminated and relatively efficient and economical refrigeration can be achieved, it will also be effective in saving energy.

[0004] Furthermore, when ice is produced simply by freezing, the air contained therein crystallizes in the form of bubbles due to its solubility, resulting in a cloudy appearance. Transparency is important for ice sculptures, and it is necessary to be able to form ice into a desired shape while suppressing cloudiness. SUMMARY OF THE INVENTION The present invention aims to provide a method and apparatus for producing frozen ice sculptures that are effective and suitable for solving many of the conventional problems.

[0005]

[Means for Solving the Problems] The above-mentioned problems are achieved by the present invention adopting the following novel characteristic configuration techniques and means. That is, the feature of the method of the present invention is that a water retaining bag made of a plastic sheet or a rubber sheet is blow-molded into the desired shape of an ice sculpture, and the bag opening is inserted into a split mold in which the same shape as the desired shape is engraved. Next, water is injected and filled from the bag opening, and the water in the water holding bag is solidified by freezing while removing air from the same bag opening.Then, the split mold is opened and the frozen bag is frozen. In this method, a frozen ice sculpture is produced by taking out the frozen ice retaining bag, and then removing the torn ice retaining bag to obtain a desired ice sculpture.

A feature of the apparatus of the present invention is that a water retaining bag made of a plastic sheet or a rubber sheet, which is blow molded to the same shape as the desired shape and filled with water, is inserted into the interior of the carved ice sculpture. An ice sculpture comprising: a freezer compartment that can freely take in and out the split molds that are inserted into the ice cubes outside the home, a refrigerator that cools the freezer compartment, and an air removal pump that communicates with an air vent pipe that is attached to the bag opening. This is a refrigeration manufacturing device.

Embodiments (Example of Apparatus) An embodiment of the apparatus of the present invention will be described in detail with reference to the drawings. FIG. 1 is a front perspective view of this embodiment with the front opening/closing door removed, and FIG. 2 is an enlarged vertical sectional view of a split mold used in this embodiment. In the figure, A is the ice sculpture freezing production apparatus of this embodiment, 1 is a sealed freezing chamber, and 2 and 3 are interiors 4 and 5 in which the desired shape of the ice sculpture is carved into the left and right halves, respectively, and the same shape is preliminarily blow-molded. In addition, a pair of left and right plastics can be stored in the freezer compartment 1 by inserting a water holding bag α made of a polyethylene plastic sheet or a rubber sheet injected with water β and inserting the bag opening α1. Alternatively, the metal split mold 6 has a fitting 7 attached to the bag opening α1 extending from the split molds 2 and 3 housed in the freezer compartment 1 at its hanging end, and communicates with an air vent pipe 9 penetrating the ceiling 8 of the freezer compartment 1. A vacuum pump 10 is an air removal pump installed on the ceiling 8, and a refrigerator 10 is installed at the bottom of the floor of the freezing chamber 1 so that the water β in the water holding bag α is gradually frozen from below.

(Method Example) An example of the method of the present invention using the apparatus A of the present invention will be described with reference to the drawings. FIG. 3 is a step-by-step explanatory diagram showing the blow molding steps (a), (b), and (c) of the water retaining bag α. The execution procedure of this example is as follows:
As a preliminary step, first the desired shape of the ice sculpture is created inside the interior 11.
, 12 into upper and lower halves of the blow molding molds 13 and 14 which are subjected to heating γ, for example, an original bag α' made of polyethylene is inserted (see FIG. 3(a)).

Next, the original bag α' is placed in a blow molding mold 13,
While heating and melting γ in the bag 14, air ε is blown from the bag opening α1, and the original bag α' is expanded and brought into close contact with the inner surface of the mold to form the water holding bag α in the desired shape of the ice sculpture (see FIG. 3(b)). after that,
The blow molding molds 13 and 14 are cooled and divided to form the water holding bag α into the desired shape of the ice sculpture, and the water holding bag α is taken out and prepared (see FIG. 3(c)).

[0010] The execution procedure of this stage is as follows: First, the blow molding mold 1 is
Split molds 2 and 3 carved into the same desired shape as the inner surface of molds 3 and 14
The water holding bag α prepared inside is inserted with the bag opening α1 exposed at the top, and water β is injected and filled through the bag opening α1 (see FIG. 2). Next, the split molds 13 and 14 are placed in the freezer compartment 1 of the separately prepared ice sculpture freezing production apparatus A, and the fitting 7 at the lower end of the air vent pipe 9 is attached to the protruding bag opening α1 (see FIG. 1). .

[0011] Subsequently, the front opening/closing door (not shown) is sealed to seal the inside of the freezer compartment 1, and the refrigerator 10 and the vacuum pump 6 are started to carry out freezing for the required time while drawing air. After freezing is complete, open the front door and place the split molds 2 and 3 into freezer compartment 1.
Take it out. Both the split molds 2 and 3, or the ice holding bag α containing the frozen molded ice sculpture after splitting the split molds 2 and 3, were delivered to the site, the bags were torn open to expose the ice sculpture, and the excess portion was removed. Scrape it off and place it on the table as a decoration for parties, etc.

0012

[Effects of the Invention] Thus, according to the present invention, by using the holding bag as a consumable item and drawing air with a vacuum pump during freezing, it is possible to mass-produce transparent ice sculptures with the same design without producing cloudy parts. Therefore, it is possible to reduce costs, and
The ice sculptures produced in this way can be transported with the split molds, and by covering them with foamed polystyrene protective material to suppress the rise in temperature, they can retain their shape for a considerable time, so they can be sold as commercial products by distribution systems. It has excellent effects such as being able to be used widely in the market.
