your location:durian tunnelliquid nitrogen quick freezing machinethe principle is to use the ultra-low temperature and high heat exchange rate of liquid nitrogen to quickly freeze durian in a very short time.
liquid nitrogen is a colorless, odorless, non-toxic liquid with a very low boiling point, so it can quickly cool objects to very low temperatures.
during the freezing process of durian, the liquid nitrogen will evaporate rapidly, thereby absorbing the heat of the durian and causing the temperature of the durian to drop rapidly.
at the same time, the liquid nitrogen quick freezing technology also has the characteristics of rapid lifting and two-way circulation, which allows the frozen durian to exchange heat evenly with the cold air flow during the entire process.
thus achieving rapid cooling and freezing. such a rapid freezing process can effectively reduce the loss of nutrients in durian while maintaining its original color, flavor and quality.
