Development of W/O emulsion to form harmless ice slurry to human being in Revue internationale du froid, Vol 32, Issue 3 (2009)
[article]
Titre : Development of W/O emulsion to form harmless ice slurry to human being Titre original : Développement d'une émulsion huile/eau sans toxicité pour l'homme, pour les coulis de glace Type de document : texte imprimé Année de publication : 2012 Article en page(s) : pp. 411-420 Langues : Anglais (eng) Français (fre) Catégories : 621.5 : Technique pneumatique, du vide, des basses températures Mots-clés : Coulis de glace Entreposage frigorifique Index. décimale : 621.56 Technique des basses températures : réfrigération, pompe à chaleur Résumé : In order to form ice slurry in ice storage, W/O emulsion was made from water–oil mixture with a small amount of surfactant. And, it was proved that ice slurry could be formed even in a metal vessel, which is expected to improve ice formation rate, without ice adhesion to a cooling vessel wall because of a structural feature of the emulsion. In this paper, authors proposed application of ice slurry to cold storage of foods. In order to apply ice slurry to cold storage of foods, a new harmless ice slurry to human being was formed by cooling a new W/O emulsion made from tap water–edible oil mixture with a small amount of edible emulsifier. And, the fundamental characteristics and availability of new W/O emulsion-ice slurry formed were clarified. Finally, it was concluded that new harmless ice slurry to human being could be fully applied to cold storage of foods.

Vacuum freezing type ice slurry production using ethanol solution 1st report: Measurement of vapor–liquid equilibrium data of ethanol solution at 20 °C and at the freezing temperature in Revue internationale du froid, Vol 32, Issue 3 (2009)

Titre : Vacuum freezing type ice slurry production using ethanol solution 1st report: Measurement of vapor–liquid equilibrium data of ethanol solution at 20 °C and at the freezing temperature Titre original : Production de coulis de glace à l’aide d’une solution d’éthanol et d’un processus de refroidissement sous vide. 1er rapport : données sur l’équilibre vapeur-liquide de l’éthanol à 20 °C et le point de congélation Type de document : texte imprimé Année de publication : 2012 Article en page(s) : pp. 387-393 Langues : Anglais (eng) Français (fre) Catégories : 621.5 : Technique pneumatique, du vide, des basses températures Mots-clés : Coulis de glace Éthanol liquide-vapeur Température de congélation Index. décimale : 621.56 Technique des basses températures : réfrigération, pompe à chaleur Résumé : In this study, an original method for the production of ice slurry from ethanol solution without using a refrigerator is proposed. This system has advantages compared with similar existing systems using materials other than ethanol solution. In this paper, the vapor–liquid equilibrium data of ethanol solution at 20 °C and at the freezing temperature are measured, which is necessary to calculate the COP of this ice slurry producing system. In the experiments, two experimental methods are proposed to measure the saturated pressure and the vapor composition of ethanol solution. Each method has an advantage in their operating temperature range. As a result, the vapor–liquid equilibrium diagrams of ethanol solution at 20 °C and at the freezing temperature, and approximations of saturated pressure of various concentrations of ethanol solution for varying liquid temperature, are obtained.

As was introduced in the first report, this system has advantages compared with similar existing systems using materials other than ethanol solution. In this paper, the process of producing ice slurry using this method was observed, and the relationship between ethanol concentration of the solution and that of the vapor, which evaporated from the ice-solution mixture, was measured. It was found that the ethanol concentration of vapor was lower than that in the condition that did not produce ice. The composition of vapor was found to be affected by the sublimation of the ice produced. Finally, the COP of this system was estimated and the effect of sublimation of ice was investigated.
