FLNT1000
Our FLN1000 liquid nitrogen tunnel freezer is a professional cryogenic freezing solution engineered for seafood processing and high-value food production. Leveraging advanced liquid nitrogen technology, the system operates at an ultra-low temperature of -196℃, enabling rapid heat extraction and instant freezing when in contact with food. The ultra-high heat exchange rate delivers fast, uniform freezing, forming minimal ice crystals to preserve food cellular structure. This design effectively prevents moisture loss and nutrient degradation, retaining the original color, flavor, and texture of seafood. Constructed with food-grade stainless steel, the freezer aligns with strict global food safety standards, making it ideal for seafood processing factories, frozen food manufacturers, and cold chain processing centers.

The -196℃ cryogenic process forms minimal ice crystals, eliminating damage to food cell structures. This ensures zero moisture loss and no drying shrinkage, maximally preserving the fresh taste and nutritional value of high-value seafood.
The entire main structure uses SUS304 stainless steel, fully complying with international food processing hygiene and safety regulations, suitable for long-term use in high-humidity food production environments.
The system adopts a complete inverse heat exchange design, guiding vaporized nitrogen evenly to the freezer’s front end, improving nitrogen utilization efficiency and reducing long-term operating expenses for production enterprises.
With a simple, robust structure, the freezer is easy to install, operate, and maintain. No professional technical personnel are required for daily operation, cutting labor and training costs for enterprises.
The liquid nitrogen freezing system produces no pollution or excessive noise, meeting global environmental protection requirements for food production workshops.
This liquid nitrogen tunnel freezer is specially designed for high-value seafood processing, including block shrimp, whole tuna, caviar, abalone, cooked fish, and other aquatic products. It also suits freezing high-value prepared foods, pasta products, and premium meat products, catering to seafood processing plants, frozen food production enterprises, cold chain processing centers, and catering supply chain service providers.
The tunnel cycle time is adjustable from 8 to 40 minutes, flexibly set according to the size, type, and freezing requirements of different food products.
Yes, the equipment’s main body uses food-grade SUS304 stainless steel, fully complying with food safety and hygiene regulations of major global markets.
For standard 200×200×60mm block shrimp (3kg per unit), the rated production capacity is 1000-1100kg per hour.
No, the equipment features a user-friendly design for simple operation. Basic on-site training is sufficient for daily use, with no need for full-time professional technical personnel.
We provide customized cryogenic freezing solutions tailored to the production scale, product type, and workshop layout of seafood processing and food production enterprises.
