Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an ice making method.

[Prior art]

As an example of the ice making method, water is stored in a cooling tank that is cooled from the outer circumference by a cooling medium, and ice is gradually grown on the inner circumference of the cooling tank while stirring the water with an impeller installed upright in the cooling tank. There is a way to make ice.

This ice making method is known as a method for producing highly transparent ice.

[Problem that the invention seeks to solve]

By the way, when colored objects are included in extremely transparent water, it has a high aesthetic appeal.When the colored object is a fruit, it becomes a colorful frozen dessert, and when it is a flower or other beautiful object, it becomes a richly colored frozen dessert. It is highly useful as ice decorations, ice containers, etc. However, these types of ice have not been manufactured using the ice making methods described above, and it is desired to establish a method for manufacturing these ices.

(Means for Solving the Problems) The present invention provides the above-described ice making method, in which ice is made with a colored object supported by a support that allows water to flow around the outer periphery of the impeller of the cooling tank. This ice cream is characterized by removing the lingering odor after ice making.

In the present invention, the colored object may be inorganic or organic, animal, plant, food, or non-food, but small fruits, fruit pieces, small flowers, petals, etc. are particularly preferred. Also,
As a method of supporting these colored objects, when the ice has grown to a predetermined thickness on the inner circumference of the cooling tank, a water-permeable cylindrical support made of wire mesh, resin net, etc. is placed on the inner circumference of the ice. A method of arranging ingredients and supporting a colored object between the two, a method of supporting a colored object in a skewer shape using a support consisting of a frame and a skewer suspended from the same frame, an ice-making frame There are methods of supporting colored objects within the storage frame.

[Action/effect of the invention]

According to this ice-making method, a colored object can be supported by ice and a support or a support alone, and the colored object can be maintained at a desired position and in a desired state even while water is being stirred by an impeller. Therefore, colored objects are buried in the resulting water, resulting in colorful frozen desserts, ice decorations, and ice containers.

〔Example〕

The present invention will be explained below based on the drawings. FIG. 1 shows an example of a cooling tank used in the method of the present invention, and this cooling tank 11 is connected to a refrigeration circuit as shown in FIG. incorporated and used. In such a refrigeration circuit, the compressor 21
, the condenser 22 and the cooling tank 11 are connected to the connecting pipes 23a, 23
b and 23c are connected in series by a sequential ring conduit, and a dryer 24a and a capillary tube 24b are interposed in the connecting conduit 23b. In addition, the connection pipe 23
An electromagnetic on-off valve 24 is provided in the bypass pipe 23d between a and 23b.
When the on-off valve 24C is closed, the cooling medium passes through the pipes 23a-23b-23c in order to cool the cooling tank 11, and when the on-off valve 24c is opened, the cooling medium cools the cooling tank 11. -2
3d to 23c are rotated in order to heat the cooling tank 11.

The cooling tank 11 has a cylindrical shape with a bottom, and has cooling pipes 12 wound around its outer periphery in multiple stages in the vertical direction, and is embedded in a heat insulating layer 13 and disposed within a case 14 of the refrigeration system.

An impeller 15 is removably erected in the center of the cooling layer 11, and is rotatably supported by a large diameter gear 17a rotatably supported on the lower surface of the lid 16. This large diameter gear 17a meshes with a small diameter gear 17b driven by an electric motor (not shown), and is driven by the small diameter gear 17b to rotate the impeller 15. In addition, the reference numeral 18 in the figure
a is a drainage pipe, and 18b is a drainage pipe 18a connected to the cooling layer 1.
This is a connecting pipe connected to the drain hole 11a of No. 1.

The present invention uses such a cooling tank 11 to manufacture ice. In manufacturing, first, the drain pipe 18a is fitted and supported in a holder (not shown) of the case 14, and a predetermined amount of ice is placed in the cooling tank 11. Then, the impeller 15, both gears 17a and 17b, and the lid 16 are inserted as shown in the drawings. In the first embodiment of the present invention, the refrigeration system is started in this state. This allows impeller 15
As the cooling medium rotates, cooling gas as a cooling medium flows through the cooling pipe 12 to cool the cooling tank 11 from the outer periphery. This operating state is continued for a predetermined time to generate cylindrical ice 31a having a predetermined thickness, for example, about 5 mm, on the inner peripheral side of the cooling tank 11, and in this state, the operation is interrupted and the lid 16, large diameter gear 17a, and impeller are removed. 15 is removed and a cylindrical support 19A made of a full mesh or resin 11 mesh is placed concentrically into the inner hole of the ice 31a, and a small flower 32 is placed in the gap between both 19A and 313.
Insert and support multiple pieces a. Thereafter, the impeller 15, large-diameter gear 17a, and lid body 16 are inserted in the same manner as above, and operation is resumed in this state and continues for a predetermined time until the ice is formed into a cylindrical ice 31b having a predetermined thickness, for example, about 15 mm. generate. In this state, stop again and remove the lid 16, large diameter gear 17a, and impeller 15, and also remove the support 1.
Take out 9A, then impeller 15, large diameter gear 17a
Then, the lid 16 is set, and the operation is restarted and continued for a predetermined period of time. As a result, as shown in FIG. 3, a bottomed cylindrical ice vessel 31c in which a plurality of flowers 32a are embedded is formed. FIG. 4 shows a perspective view of the support 19A, and the support 19A has a sheet-like net 19a shaped into a circular body with a predetermined diameter, as shown in FIGS. 5(a) and 5(b). It is formed by fixing both upper ends with band-shaped clips 19b. Therefore, the diameter of the support body 19A can be changed arbitrarily.

In the second embodiment of the present invention, the method shown in FIG. 6 is adopted. The support 19B in this method consists of a metal frame 19c and a plurality of wire skewers 19d suspended from the metal frame 19c, and each skewer 19d has 3 flower petals, fruit pieces, etc.
2b is supported like a skewer. In this method, the frame 19c of the support 19B is hung on the upper end of the cooling tank 11 containing a predetermined amount of water, and each skewer 19d is suspended in water, and in this state, the impeller 15, large diameter gear 17a
Then, set the lid 16 and start making ice. In this case, the support 19B may be taken out either at the end of the ice making or during the ice making.
If B is heated, it can be easily taken out of the water.

In the third embodiment of the present invention, the method shown in FIG. 6 is adopted. The support 19C in this method is a cylindrical ice making frame divided into three parts in the circumferential direction, and the ice making frame is placed in the cooling tank 11 containing a predetermined amount of water before the impeller 15, large diameter gear 17a and lid 16 are placed. Place it in In this method, as in the first embodiment, ice 31d of a predetermined thickness is formed on the outer periphery of the support 19C by first operating for a predetermined period of time, and in this state, the ice 31d is placed in each accommodation frame 19e of the support 19C. After adding small fruits, vegetables, etc. 32c, the operation is restarted and continued for a predetermined period of time to complete ice making. After that, the support 19
If you take out C with the ice and twist it left and right, the ice corresponding to each storage frame 19e will be ii! Ie. These pieces of ice are highly transparent ice in which fruits etc. 32c are buried.
