This liquid nitrogen tunnel freezer leverages -196°C liquid nitrogen (LN2) to deliver instant freezing performance, preserving product freshness, natural color, and nutritional value for high-value goods. With a rapid temperature reduction rate of 5-10°C per second, the system minimizes ice crystal formation and cell damage in delicate products, making it a suitable choice for food processing and pharmaceutical production lines. Compared to conventional air-blast freezing systems, this ultra-low temp design cuts total freezing duration by 80%, enabling more flexible production scheduling and supporting just-in-time production models for industrial clients.
LN2 spray freezing at -196°C creates an instant crust freeze on product surfaces, locking in internal moisture and reducing drip loss during thawing. This design lowers product weight loss by 30% compared to conventional freezing methods, preserving product yield for commercial production lines.
The standard tunnel configuration processes up to 1,000 kg of product per hour, with a compact footprint that fits seamlessly into existing production layouts. For high-volume manufacturing facilities, modular extension kits are available to upgrade total capacity to 2,000 kg/h without full equipment replacement.
The system releases fine LN2 mist with 50-100μm droplets, delivering even cooling across the entire belt surface without mechanical stress. This gentle freezing process preserves the structural integrity of fragile items such as meringues and fresh herbs.
Engineered with optimized LN2 injection nozzles, the freezer reduces LN2 consumption by 15% compared to older generation models. A closed-loop cold vapor recovery system pre-cools incoming products, further improving energy utilization efficiency.
The tunnel structure measures 11m × 2.3m in footprint, with a 2.2m overall height. The low-profile design allows integration under existing conveyors, making the system suitable for production facilities with limited floor space.

This ultra-low temp tunnel freezer serves two primary industrial sectors with strict quality requirements. In food processing, it is widely used for sushi-grade fish, gourmet pastries, probiotic yogurts, leafy greens, and fatty meats, maintaining product texture, flavor, and nutritional content that cannot be achieved with conventional slow freezing. In pharmaceutical processing, the system provides stable ultra-low temperature conditions to preserve temperature-sensitive biologics, supporting strict production quality and compliance requirements for medical manufacturing. The food-grade non-stick belt material meets international food contact safety standards, making the equipment suitable for regulated production environments.
For enterprise customers with specific production requirements, the system offers multiple customization options. Available add-ons include integrated weighing systems with ±1g accuracy and inline metal detectors for production quality control. A nitrogen recovery unit is also available to reduce LN2 operating costs by 20%. We provide turnkey LN2 solutions for full project deployment, including on-site storage tanks with 500-5,000 liter capacity, vaporizers, and standardized safety training for equipment operators. This end-to-end support eliminates multi-vendor coordination work for commercial users.
The whole machine comes with a 12-month warranty, with a 5-year warranty covering critical components. We offer 24/7 emergency technical support for all installed systems. According to client operation data, the equipment achieves 99.5% uptime in continuous production scenarios. All systems are manufactured in compliance with GMP, ISO 14001, and FDA 21 CFR Part 11 standards, with full documentation available for audit purposes. CO₂-neutral LN2 sourcing options are available for facilities pursuing carbon reduction targets.
Average LN2 consumption is approximately 1 ton of LN2 per ton of processed product, varying by product type and initial temperature. Leafy greens consume around 0.8 tons of LN2 per ton of product, while fatty meats consume around 1.2 tons per ton.
Yes. The compact design has a footprint of 11m × 2.3m and a total height of 2.2m, fitting into tight production spaces and compatible with existing conveyor systems. Voltage can be customized to match on-site power specifications, and modular extensions are available to adjust production capacity.
The system includes explosion-proof electrical components, an oxygen monitoring system that alarms at O₂ levels below 19.5%, and automatic LN2 shutoff valves for emergency conditions. Operator safety training is included in the turnkey solution package.
The equipment complies with GMP, ISO 14001, and FDA 21 CFR Part 11 standards. The conveyor belt uses FDA-approved PTFE-coated stainless steel, meeting food contact safety requirements for food and pharmaceutical production.
