Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to dry ice having excellent fragrance and a method for producing such dry ice,
In particular, the present invention relates to a method for producing a dry ice scrap containing a dry ice cut-off portion which is hard to be a product or a product as a raw material.

[0002]

2. Description of the Related Art Generally, dry ice is produced by compression-molding dry ice snow obtained by spraying liquid carbon dioxide into a square shape. When this dry ice is supplied to the market, chips, cracks, and melts easily occur at the end of the dry ice corners during transportation, and a portion including such chips, cracks, and melts has no commercial value. Further, since the dry ice horn is sold by cutting it into the necessary amount based on the weight, it is necessary to cut the dry ice horn into the necessary amount. Even in this case, the cut off odd dry ice is generally difficult to become a trading product. Non-traded dry ice such as dry ice containing these cracks, chips or melts is generally referred to as dry ice scrap.

The main purpose of using dry ice is to preserve fresh foods and frozen foods and to preserve bodies. For this purpose, it has been attempted to incorporate substances having a bactericidal / antibacterial effect, such as essential oil and allyl isothiocyanate, which further enhance the anti-corruption effect of foods and remains into dry ice (Japanese Patent Laid-Open No. 2001-213701, JP-A-11-1
16226 publication).

[0004]

No technique has been developed for regenerating dry ice scraps such as dry ice remaining after being sold by being sold due to cracking, chipping and melting, into dry ice having a high added value. Further, not dry ice that prevents the generation of offensive odors, dry ice that can emit any fragrance with high palatability has not yet been developed. The present invention provides a method for producing dry ice, which emits a fragrance with rich palatability, and particularly dry ice having such a high added value, from the dry ice scraps as described above.

[0005]

SUMMARY OF THE INVENTION The present invention is dry ice containing a solid aroma component, particularly a solid aroma component containing an alkaline carbonate and an organic acid. Further, the present invention is a method for producing dry ice having a solid aroma component, which comprises compression molding a mixture of powdered dry ice and a solid aroma component.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Dry ice containing a solid fragrance component of the present invention has a property that the solid fragrance component is decomposed at the same time when the dry ice is sublimated and converted into a gas, and an aromatic substance in the solid can be released Have By arbitrarily selecting this aromatic substance, it is possible to give aroma having a high palatability to dry ice, which is originally odorless, and increase the added value of dry ice. In particular, the dry ice of the present invention has the advantage that the solid aroma component hardly remains even after sublimation, so that there is no restriction on the usage scene.

The solid aroma component in the present invention is a component containing an aromatic substance, an alkaline carbonate and an organic acid, particularly a component in the form of granules or powder. With the sublimation of dry ice, this solid fragrance component reacts with moisture in the air to generate carbon dioxide gas, and is itself decomposed and vaporized. Therefore, the aromatic substance can be efficiently diffused into the atmosphere together with the sublimation of the dry ice itself.

As the solid fragrance component of the present invention, it is preferable to use an effervescent bath agent utilizing an alkaline carbonate and an organic acid in the form of granules or powder of an appropriate size. The effervescent bath agent as used herein means a bath agent which is foamed by a combination of an alkaline carbonate and an organic acid. A large number of such effervescent bath agents are commercially available, and many reports have been made on their components and production methods. In the present invention, any material can be used as long as it decomposes and gasifies while generating carbon dioxide gas by reacting with moisture in the air as the dry ice sublimes.

When a granular commercially available effervescent bath agent is used, it can be used as it is, but it is preferable to use it by further pulverizing it with a pulverizer.
In the case of a tablet-type effervescent bath agent, this is similarly crushed before use.

Further, granules or powders may be prepared from an aromatic substance, an alkaline carbonate and an organic acid by using a suitable vaginal agent without containing an ingredient effective only as a bathing agent.

The aromatic substance used in the present invention is not particularly limited in kind, and may be a natural aromatic substance or an organic synthetically produced substance. Further, in the present invention, the aromatic substance can be used in the form of either liquid or solid without being affected by its physical properties, and can impart an arbitrary aroma with high palatability to dry ice. In addition, it is preferable to use a substance having aromaticity and sterilization and bacteriostatic effects in terms of function, and it is preferable to use a substance having high volatility in terms of emission to the atmosphere.

As the alkaline carbonate, a water-soluble salt,
For example, sodium carbonate, potassium carbonate, sodium hydrogen carbonate, potassium hydrogen carbonate and the like are preferable.

As the organic acid, water-soluble fumaric acid, succinic acid, citric acid, malic acid, oxalic acid, tartaric acid and the like are preferable.

The solid fragrance component is obtained by granulating the above-mentioned aromatic substance, alkaline carbonate, and organic acid into a granule or powder by a general method such as extrusion granulation using a suitable vat-forming agent or binder. Can be used.

When a solid aromatic component is newly produced from an aromatic substance, an alkaline carbonate and an organic acid as described above, in addition to these raw materials, monosaccharides such as glucose, galactose and fructose as excipients, Powders of disaccharides such as maltose, lactose and sucrose, polysaccharides such as starch and dextrin, cellulose derivatives such as cellulose, methyl cellulose and ethyl cellulose can be used. Also,
If necessary, a surfactant, for example, a nonionic surfactant such as sorbitan fatty acid ester, glycerin fatty acid ester, sucrose fatty acid ester, polyglycerin fatty acid ester, polyoxyethylene sorbitan fatty acid ester can be added in an appropriate amount.

When preparing a granular solid aroma component, silica gel, cellulose, acetylated chitin,
Porous particles such as polyethylene, polyurethane and polypropylene can be used as the granular carrier.

As described above, the solid fragrance component in the present invention may be produced mainly by a general production method for preparing a bath fragrance. The blending amount of the solid aromatic component in the dry ice of the present invention may be an appropriate amount, and 0.2 wt% is particularly preferable in the contained dry ice.

The dry ice containing the solid fragrance component of the present invention can be produced by adding and mixing the above-mentioned solid fragrance component to dry ice snow prepared according to a conventional method, and then compression-molding the dry ice snow. From the viewpoint of manufacturing cost or effective use of dry ice scraps, it is preferable to manufacture from dry ice scraps. The dry ice scraps referred to in the present invention are products such as cracked, chipped or melted dry ice from production to sale, or odd dry ice produced when cutting dry ice corners to a necessary amount. It refers to dry ice of various forms and sizes that have lost value. Originally, these are not treated as products as they are, as they impair the commercial value of dry ice. By positively utilizing such dry ice scraps, the dry ice of the present invention can be produced more advantageously in terms of energy consumption and cost as compared with the case of newly producing dry ice from carbon dioxide gas.

The production of dry ice containing solid aroma components using dry ice scraps as raw materials
Step of pulverizing with a crusher, step of adding and mixing the above solid aroma component to powdery dry ice, compression of the mixture of powdery dry ice and solid aroma component into standard dry ice with a pressure molding machine Including the step of molding.

As the crusher used in the present invention, a commercially available machine such as a crusher manufactured by Murao Engineering Co., Ltd. may be used as it is without any special equipment and operation. Further, in the case of mixing dry ice snow or powdered dry ice with a solid aroma component, a powder mixer used for ordinary mixing and kneading, for example, a closed-type stirring mixer, a V-type mixer or a fluidized bed mixer. And the like can be used. Further, as the dry ice pressure molding machine, a normal equipment capable of pressure molding dry ice snow may be used as it is.
