Tunnel de congélation à l’azote liquide

The liquid nitrogen tunnel freezer is a large-scale freezing machine suitable for large-capacity processing production on Food factory assembly lines. It has the features of strong freezing capability, simple operation, and a high degree of automation. The liquid nitrogen freezer employs new heating technology, temperature control techniques, and liquid nitrogen dispersion technology to ensure uniform and stable control over the processes of programmed heating, constant temperature maintenance, and cooling. It uses liquid nitrogen as a refrigerant to meet cooling and environmental requirements. The freezer comes in various specifications and can be designed and manufactured according to requirements.
The low temperature can reach -196 °C. When it comes into contact with food, it quickly absorbs heat upon vaporization. The ultra-low temperature and high heat exchange rate enable rapid freezing. This rapid freezing results in small ice crystals, helping to maintain the texture of the food, preventing moisture loss, and achieving nearly zero loss, preserving the original color, flavor, and quality of the food. The vaporized refrigerating nitrogen gas is evenly controlled and directed to the front end of the freezer, achieving heat exchange and thereby increasing the efficiency of nitrogen utilization. This equipment, utilizing liquid nitrogen as a refrigerant, represents a new type of device in the food freezing industry.
