tunnel typeliquid nitrogen quick freezing machineit is a kind of quick freezing equipment used in food processing. its principle mainly involves the physical properties and thermodynamic principles of liquid nitrogen.

liquid nitrogen quick freezing machinethe low temperature characteristics and high heat capacity of liquid nitrogen are used to quickly reduce the temperature of food, thereby achieving rapid freezing.

liquid nitrogen is an extremely low-temperature liquid with a boiling point of approximately -196 degrees celsius under normal pressure. when liquid nitrogen comes into contact with food,

due to its high heat capacity, it can quickly absorb the heat in the food, causing the food to quickly cool and crystallize into ice, thereby achieving a quick freezing effect.

in tunnelliquid nitrogen quick freezing machinein the process, liquid nitrogen is sprayed onto the surface of the food through a nozzle or spray device, and the food passes through the tunnel-type equipment on the conveyor belt.

continuous contact and cooling with liquid nitrogen cause the temperature of the food to drop rapidly. at the same time, through the control of liquid nitrogen, precise temperature control of food can be achieved to ensure quick freezing effect and food quality.

in general, tunnel-type liquid nitrogen quick freezing machines use the low-temperature characteristics and high heat capacity of liquid nitrogen to quickly freeze food by quickly absorbing food heat.
