Recently, an ice-making confectionery machine has been developed and put into practical use, allowing users to easily make sherbet, frozen pudding, and frozen jelly at home. Such ice-making confectionery machines have a structure in which a refrigerant is housed between double containers. In order to make, for example, sherbet using such an ice-making confectionery machine, the ice-making confectionery machine is placed in the freezer compartment of a refrigerator for a predetermined period of time, the refrigerant is frozen, and then taken out, syrup is placed in the ice-making confectionery machine, and the syrup is stirred to make ice. It can be made by

題があつた。また、前記冷媒剤は被冷却物との熱
交換性が低く、しかし冷却持続性（保冷性）が低
いため、シロツプ等の被冷却物を充分に氷結でき
ないという問題があつた。 By the way, viscous polyvinyl alcohol has conventionally been used as the above-mentioned refrigerant. However, since this refrigerant expands when frozen, when it is housed in the double container of the ice-making confectionery machine, there is a problem that the container may be damaged due to the expansion force. Furthermore, since the refrigerant has low heat exchangeability with the object to be cooled and low cooling sustainability (cold retention), there is a problem in that the object to be cooled, such as syrup, cannot be sufficiently frozen.

The present invention aims to provide a refrigerant that hardly expands during cooling, has good heat exchange performance with the object to be cooled, has excellent cold retention, has low fluidity, and is safe. .

The inventors of the present invention have conducted intensive research to solve the drawbacks of conventional refrigerants, such as expansion during cooling and poor heat exchange and cold retention properties. By using the prepared paste-like material and adding a predetermined amount of salt mainly composed of sodium chloride to a composition of a predetermined viscosity, as mentioned above, there is almost no expansion during cooling, and the material to be cooled can be cooled. In addition to having good heat exchange properties with
We have discovered a safe refrigerant that has excellent cold retention properties, has low fluidity, and is safe.
即ち、本発明は有機増粘剤に水を加えて調製し
たペースト状物に、塩化ナトリウムを主成分とす

ズにしてなる冷媒剤である。 That is, the present invention is a refrigerant made by adding 5 to 16% by weight of a salt containing sodium chloride as a main component to a paste prepared by adding water to an organic thickener to give a viscosity of 2 to 3000 poise. be.

かる有機増粘剤としては、小麦澱粉、メチルセル

等を挙げることができる。 The organic thickener has the function of increasing the viscosity of the refrigerant and imparting heat storage properties (cold retention properties). Such organic thickeners include wheat starch, methylcellulose or carboxymethylcellulose (CMC).
etc. can be mentioned.
上記塩化ナトリウムを主成分とする塩は、冷媒

換性を充分に達成できず、かといつてその添加量
が16重量％を越えると、冷媒剤の保冷性を低下さ
せる。特に、前記塩の好ましい添加量は、８〜12
重量％の範囲である。 The salt containing sodium chloride as a main component serves to suppress expansion of the refrigerant during cooling and to improve heat exchange performance. Examples of such salt include common salt. The reason why the amount of salt added is limited to the above range is that if the amount added is less than 5% by weight, sufficient expansion suppression effect and heat exchange performance during cooling cannot be achieved. If it exceeds %, the cold retention properties of the refrigerant will be reduced. In particular, the preferable addition amount of the salt is 8 to 12
% by weight.
本発明の冷媒剤の粘度を限定した理由は、その
粘度を２ポイズ未満にすると、冷媒剤の流動性が

り過ぎて充填性や気泡が発生し易くなる。特に、
前記冷媒剤の好ましい粘度は９ポイズ〜3000ポイ
ズの範囲である。 The reason why the viscosity of the refrigerant of the present invention is limited is that if the viscosity is less than 2 poise, the fluidity of the refrigerant will not only increase but also the heat storage property will decrease; , the viscosity becomes too high, resulting in poor filling properties and easy generation of bubbles. especially,
The preferred viscosity of the refrigerant is in the range of 9 poise to 3000 poise.
なお、本発明の冷媒剤は前記ペースト状物と塩

が全く認められなかつた。 Therefore, the refrigerants of Examples 1 and 2 were housed in double containers to produce ice-making confectionery machines, and these ice-making confectionery machines were placed in the freezer compartment (-22°C) of a refrigerator and cooled for about 16 hours. , remove the ice cream confectioner from the freezer compartment,
The operation of raising the refrigerant to room temperature again and then cooling the refrigerant in the freezer compartment was repeated 300 times to check for damage to the double container. As a result, no cracks or damage due to expansion of the refrigerant were observed in the containers of the ice-making confectionery machines containing the refrigerants of Examples 1 and 2.

とが確認できた。 Furthermore, when syrup was poured into each ice-making confectionery machine after being cooled in the freezer, the syrup froze in about 5 minutes, making it possible to easily make the desired sherbet. Furthermore, even when the syrup was re-filled into the ice-making confectionery machine after making the sherbet one time, the desired sherbet could be made in a short time almost in the same way as the first time. From this, it was confirmed that the refrigerant agent of the present invention is excellent in both heat exchange performance and cold retention property (cooling sustainability).
