Description

  Related to ice tableware and molds.

  At present, when making ice tableware and shaped objects, it is common for craftsmen to scrape off ice blocks with a chisel.

  Japanese Utility Model Publication No. 05-086270

  Patent Document 1 discloses an ice cup and its support. However, in the case of ice tableware for solid foods, the ice melts at the environmental temperature during use, and the food on the tableware is immersed in water. There is also a need for a mold that can be easily created.

  The means of the present invention is characterized in that the mold is composed of oil having a solidification temperature of 0 ° C. or higher.

  Oils and fats having a high freezing point can be melted or softened and molded and then solidified at a temperature lower than the freezing point temperature to be used as a mold for molding. Since the freezing point of the oil and fat is higher than the freezing point temperature of ice, the oil and fat is surely solidified at a temperature at which ice can be formed.

  Another means is characterized in that the mold is constituted by a hydrophobic clay formed by mixing oil with a fine powder capable of retaining a lipophilic oil partly or entirely.

  In the type of ice that freezes water to make ice by mixing oil with lipophilic fine powder to make hydrophobic clay, a general hydrophilic clay consisting of hydrophilic clay material and water is used. Thus, moldability is good and mold release is easy, and even if water is added, the viscosity of the mold clay does not decrease.

  In another means, the upper surface position of the lower mold of the mold is configured to be higher than the uppermost position of the molding cavity of the upper mold when the mold is assembled.

  In one example, when forming by freezing the liquid, a large amount of liquid is put in the lower mold, and the upper mold is filled with the liquid while the upper mold is covered and the liquid stored in the lower mold is overflowed from the drain. By configuring the upper surface of the lower mold so that it is above the uppermost position of the molding cavity of the upper mold, even if liquid leaks into the upper and lower mold part, the liquid level is lower than the uppermost part of the upper mold cavity. Can be prevented.

  Another means is characterized in that a hole penetrating to the outside is provided in the vicinity of the uppermost cavity of the upper die of the mold, and spiral screws are provided on the upper mold outer wall surface and the lower mold inner wall surface.

  By providing spiral screws on the outer wall surface of the upper mold and the inner wall surface of the lower mold, the upper mold moves upward by twisting the upper mold after freezing of the workpiece, and air is released from the hole provided near the top of the cavity. The molded product can be easily taken out from the upper mold.

  In another means, in a tableware frozen by putting a liquid into a mold, a drainage hole is provided near the bottom of the tableware.

  In one example, in the case of a tableware such as a dish that serves as a solid material, when it is made of ice, the iced food melts at the ambient temperature and becomes soaked. However, this inconvenience can be prevented by providing a drain hole near the bottom.

  In another means, a leg is provided around the drainage hole.

  In one example, in the ice dish provided with the drainage hole described above, the water drained from the drainage hole and the melted water of the ice dish outer wall accumulate at the bottom of the ice dish outer wall in a normal temperature environment, This pooled water has a much higher heat transfer coefficient than the surrounding air, which will accelerate the melting of the ice tableware itself. However, by providing the legs on the ice tableware, the legs can melt first and the melting of the tableware body can be delayed.

  Another means is characterized in that the metal plate is brought into contact with an ice molding mold near the portion where the thickness of the contents is the thickest to freeze.

  When the object to be formed of the liquid in the mold is evenly cooled and frozen from the periphery, freezing starts from the surface in contact with the mold, and freezing proceeds to the center. If the surroundings freeze first, a large pressure is applied to the unfrozen water inside, and if the cooling is continued further, the outer ice will be broken by the pressure. When such cracks enter, the appearance of the ice model is impaired. However, the metal plate is brought into contact with the wall surface of the thick part and cooled only on one side, so that the freezing start part of the molded object in the inside is designated as a specific one side and frozen from the freezing start face to the opposite face. Therefore, cracks in the ice model can be prevented.

  The mold is composed of a mixture of a lipophilic clay material and a high melting point oil, so that the mold can be easily molded at room temperature, cooled, poured into liquid food or liquid, and frozen. A model can be produced. In the conventional general method, if the ice making mold is made of resin or metal, in order to form into another shape, another mold for ice making mold is made again or the material block is shaved. I had to put it out and process it. However, in the present invention, it is possible to easily change the mold to another shape again by bringing the oil clay mold to room temperature or heating. Further, since clay is hydrophobic, the viscosity of the clay does not change depending on the molding object of water or an aqueous solution, and mold release is relatively easy without adversely affecting the molding object.

  There is a need for a mold and a molded product that can easily create an ice model and the model is beautiful and can be used for a relatively long time. The mold for making ice in Fig. 2 is a mixture of olive oil with tocophenol added to a lipophilically modified clay material (clay mineral fine powder combined with organic base; hereinafter referred to as "hydrophobic clay material"). Made of clay. By mixing olive oil with hydrophobic clay material, the freezing point of olive oil is much lower than normal temperature, but the hydrophobic clay of the mixture can be easily molded by hand like clay composed of water and hydrophilic material It becomes like this. After molding, it is placed in a freezer and cooled to be completely solidified, and then water is poured into the lower mold (205) to overflow excess water and air from the air holes (203). Next, after covering the upper mold (202), the upper and lower molds are brought into close contact with the resin weight plate (201). Next, water is pumped out by an amount corresponding to the sum of the volume increase during freezing and the air hole volume. Thereafter, the mold is put into a freezer and frozen, and after freezing, air is press-fitted from the air hole (203) with a simple manual pump (not shown) and released from the upper mold (202). Thereafter, an external force is applied to the lower mold (205) to deform it, and air is introduced into the gap between the ice and the lower mold wall surface to take out an ice model from the lower mold. Moreover, since water has a low viscosity, water leaks from a slight gap. Therefore, it is possible to prevent water leakage from the mold splitting surface by configuring the upper surface position of the lower mold to be higher than the uppermost molding cavity position of the upper mold when the mold is assembled. Further, the metal plate (206) is brought into contact with the wall surface of the portion having the maximum thickness in the mold and frozen. The water to be added can be boiled once and cooled, and water with less dissolved gas can be obtained. Furthermore, clay mixed with oil has low thermal conductivity and can slow down the freezing rate of the water in the whole, so that it takes enough time for the gas to be removed from the water, and transparent ice can be obtained. it can. In addition, by designating a freezing start point by contact with a metal plate, it is possible to escape expansion to the opposite surface and prevent cracking of ice. In addition, lard, palm oil, and various waxes having a freezing point temperature equal to or higher than room temperature can be molded only with fat and oil without being mixed with a clay material. In a room temperature room, it is near the melting point of lard and palm oil, and it is solid but soft and can be molded. In the example of the present invention, edible oil is used, but the type of oil is not limited. By adding tocophenol to the oil, oxidation can be suppressed and deterioration of quality can be prevented for a long time.

  FIG. 1 is a cross-sectional view of an ice tray provided with a drainage hole made by another mold. A drainage hole can be created by providing a convex portion at the bottom of the lower mold, or by placing a core at the position of the drainage hole between the lower mold and the upper mold. Further, the leg (104) of the serving plate may be separately molded and bonded to the bottom of the serving plate after release. Adhesion is a water film on the surface at room temperature, so the surface of the water melted by spraying the sprayed cold spray containing chlorofluorocarbon compressed on the spray can into the spray can. Freeze and adhere. Unnecessary burrs on the air holes (203) and the parting surface are cut off with a file or a saw. Further, the hydrophobic clay material does not rot and can be used repeatedly for a long time. However, if not repeatedly used, flour may be used instead of the hydrophobic clay material. If it is difficult to release, low-melting oil (as a release agent on the inner wall of the upper mold) with the upper mold as the lower mold and the part with little unevenness and bend easy to release as the lower mold, For example, for edible use, corn oil, straw oil, and walnut oil are not frozen even at around -20 ° C). The presence of liquid oil makes it easy for air to enter from the air holes and facilitates mold release. If it is still difficult to release, the mold is broken with a knife and taken out. Furthermore, a breaking groove may be provided on the back surface or top surface of the mold so that the mold is easily broken when forming the mold.

  FIG. 3 shows a polypropylene ice mold for producing spherical ice. The lower mold (305) contains a mark line (not shown) for adding the amount of water necessary to create the molded product. After adding an appropriate amount of water, the upper mold (301) is screwed into close contact. Let The upper mold (301) is twisted in the direction in which the upper mold is removed after the molded product is frozen, and the upper mold is removed while air is introduced from the air holes (302). The lower mold is deformed so that the side wall surface opens left and right, and the molded product is taken out while air is being introduced from the side wall surface. The material of the mold may be another material as long as it has a high elastic value. In another mold release method, the mold is immersed in water at room temperature to melt the surface of the molded product and then taken out. After taking out, the surface of the molded product is refrozen in a freezer. This method is particularly effective when the mold material is a metal having high thermal conductivity such as aluminum.
