Annotation
The proposed technology uses carbon dioxide for contact treatment of fish by a method based on the use of the sublimation process – the transition of carbon dioxide from the solid to the gaseous phase with the temperature of –78 °C. The principle of this method of cooling is that snow-like CO2 is applied to the surface of the fish and the resulting carbon dioxide gas is recovered and reused for cooling. To study the technology and to apply it further the research has been conducted on cooling fish by snowlike gaseous carbon dioxide, the main task being determining the nature of the temperature field changes, the duration of cooling, the heat flux, and the amount of carbon dioxide. During cooling roundfish by snowlike carbon dioxide process time is reduced significantly and consumption of CO2 is also reduced several times unlike cooling by gaseous carbon dioxide. When carbon dioxide is obtained in the snowlike phase by throttling liquid carbon dioxide, a part of CO2 vapotrizes and thereby reduces the yield of carbon dioxide in the solid phase. The developed technology allows using this gas for cooling fish with its subsequent recuperation that to reduce consumption of carbon dioxide considerably.
