Abstract

<P>PROBLEM TO BE SOLVED: To obtain a cold insulator capable of returning to nature when being no longer in use. <P>SOLUTION: This cold insulator is obtained by letting flour comprising vegetable starch flour returning to nature absorb water to bring to a gelling state, and previously mixing horse-radish or carbon ceramic granules returning to nature with the vegetable starch flour. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a cryogen used for transporting or temporarily storing fresh food, and relates to a cryogen that does not adversely affect the natural environment at the time of disposal when it becomes unnecessary.

  A conventional cryogen is obtained by dissolving a chemical substance such as a polymer in water in a film bag of the chemical substance as a cryogen, and the cryogen is frozen and used as needed. However, when it is used, it must be treated as industrial waste because it is a chemical substance. However, this cold insulation agent is not preferable for the natural environment, and it takes a lot of labor and cost to process it.

  As described above, the conventional cooling agent has to be treated as an industrial waste after use, which requires much cost and labor. Therefore, it is an object to reduce both the water retentive material that can be naturally reverted and the bag material that wraps the water retentive material together with the material that naturally reverts, thereby reducing the processing cost and labor as the industrial waste of the cryogen.

  In order to solve this problem, the invention of claim 1 uses, as a material that absorbs and retains the water of the cryogen, a granular substance made of a polymer bond made of vegetable starch as a raw material. A non-woven fabric made of paper is used for the bag that wraps the substance. In addition, powder of yam or carbon ceramic that generates far-infrared rays is mixed into the granular material. Carbon ceramics that generate yam and far infrared rays have both antibacterial effects. With this combination, it is possible to provide a cryogen that can naturally return. In addition, carbon ceramic generates far red, is multi-hard and has many holes, and it has deodorizing and deodorizing effects as well as antibacterial and structural antibacterial effects on carbon ceramics. I can do it. By adsorbing water to a mixture of vegetable starch and yam and freezing it for freezing of foods and food materials, or adsorbing water to a mixture of vegetable starch and carbon ceramic granules, keeping it frozen and freezing Produces the effects of prevention of decay, deodorization and deodorization.

  Since the cryogen of the present invention is composed of a combination of substances that are harmless to the natural environment, it does not destroy the environment even if released into the natural environment after use. The effect is great.

BEST MODE FOR CARRYING OUT THE INVENTION

  Fig. 1 shows a vegetable starch powder or granule with ground yam grind added and mixed, and a large amount of water is added to the mixture to form a gel that is impermeable to water. It is put into a cryogen and the cryogen is frozen. 1 is a paper bag, 2 is a gel-like product obtained by absorbing water in plant starch, and 3 is a yam. The refrigeration agent having this configuration can suppress the growth of bacteria contained in the vegetable gel starch 2 and water by the yam 3, and thus can exhibit an antibacterial effect during long-term cold preservation. FIG. 2 shows another embodiment, which is a cryogen 7 formed by mixing carbon ceramic granules 6 in a gel-like product 5 in which water is absorbed in vegetable starch powder in a paper bag 4. The cold-retaining agent 7 exhibits an antibacterial effect by a far-infrared effect generated from the carbon ceramic granules, and at the same time has an unpleasant odor eliminating and deodorizing effect.

  The above two kinds of freezing agents are all harmless to natural humans and are natural environment-friendly and can be returned to nature.

  In the case of disposal after use, the cryogen of the present invention can be naturally reverted and can be produced at low cost in mass production, and thus has industrial applicability.

  It is a partial cross section front view which shows the Example of this invention.   It is a partial cross section front view which shows the other Example of this invention.
