Liquid nitrogen tunnel freezer is an efficient quick freezing equipment based on the ultra-low temperature (-196 ℃) characteristics of liquid nitrogen, widely used in food processing, biomedical and other fields.

• Ultra fast freezing: When liquid nitrogen comes into contact with food, it quickly evaporates and absorbs heat, with a heat transfer intensity 30-40 times higher than traditional equipment. It can lower the center temperature of the food to below -50 ℃ within 5-10 minutes, forming small ice crystals to reduce cell damage

• Energy saving and environmental protection: No need for mechanical compressors, energy consumption is reduced by more than 30% compared to traditional cold storage, and there are no Freon emissions

• Type: including flat mesh belt type, vibrating type, multi-layer mesh belt type, etc., supporting customized design (such as mesh belt width 0.6-1.25m)

• Material: Made of food grade 304 stainless steel liner and polyurethane insulation layer, corrosion-resistant and with excellent insulation performance

• Control system: Integrated PLC technology, supporting touch screen operation, real-time temperature monitoring (± 2 ℃), and fault alarm

• Seafood/Meat: Maintain meat elasticity and original flavor, avoid sticking (such as tuna, salmon)

• Fruits and vegetables/dairy products: retain vitamins and color, prevent structural collapse (such as strawberries, pastries)

• Other fields: Freezing of biological samples (cells, tissues) and special industrial applications

• Preservation effect: The dry consumption rate is close to zero, and the microbial inhibition effect is significant

• Automation: Supports continuous assembly line operations, adjustable mesh belt speed

• Convenient maintenance: Some models are designed with a lifting cover for easy cleaning
