The Multipass Belt IQF Tunnel Freezer is engineered for large-scale food processing operations, delivering low shrinkage and consistent product integrity across high-volume production runs. Its multi-tiered belt system improves freezing efficiency by exposing products to temperatures ranging from -30°C to -40°C during multiple passes, making it suitable for dense or irregularly shaped items such as French fries, chicken nuggets, and pizza toppings. This equipment integrates seamlessly into automated processing lines from pre-treatment to packaging, supporting stable product quality for mass-produced frozen foods.
Advanced airflow dynamics combining horizontal and vertical air streams minimize moisture loss to ≤0.15%, preserving product weight and textural properties such as crispiness in fried potato products. The uniform air distribution ensures consistent freezing results across all belt areas, avoiding uneven texture or partial thawing during processing.
The standard 3-tier configuration supports a processing throughput of up to 1,000 kg/h, with an optional 5-tier upgrade that increases output to 1,500 kg/h. The unit occupies a footprint of 11m × 2.3m, enabling capacity expansion without excessive additional floor space. This scalability adapts to growing production demands for commercial food processing facilities.
Belt speeds range from 0.5-5 m/min, with minimal product transfer between tiers to reduce physical breakage. Soft-landing chutes are integrated for fragile items such as breaded seafood, lowering damage rates during tier transitions. This design supports higher intact product ratios for finished goods, reducing production waste.
An integrated heat recovery system captures waste cold air from the freezer exhaust to pre-cool incoming products. This structure reduces energy consumption by 25% compared to single-pass tunnel freezers, lowering long-term operational costs for food production facilities.
Each belt tier is equipped with independently adjustable speed and temperature settings, enabling customized multi-stage freezing processes such as initial crust freezing followed by deep freezing. This flexibility allows one unit to handle products with different freezing requirements, reducing the need for dedicated equipment for separate product lines.

This multipass IQF tunnel freezer adapts to a wide range of food processing scenarios for commercial production facilities. It performs well with dense and irregularly shaped products, including French fries, potato wedges, chicken nuggets, breaded seafood, onion rings, mozzarella sticks, and assorted pizza toppings. The multi-pass design ensures even freezing for products with varying thicknesses, making it suitable for mixed production lines that handle multiple product types. The unit fits into automated processing workflows, connecting smoothly with upstream pre-processing equipment and downstream packaging systems to support uninterrupted continuous production. For facilities managing multiple frozen food SKUs, the stored recipe function enables quick product changeovers to reduce batch transition downtime.
We provide custom engineering services to align the equipment with specific production requirements. Available adjustments include belt width modifications and compatibility integration with auxiliary equipment such as metal detectors and weight checkers. These adjustments allow the freezer to adapt to existing production line layouts and unique product specifications.
Each unit undergoes 10,000 hours of continuous operation testing before delivery, and holds CE, UL, and CSA certifications for global market compliance. The standard full-unit warranty covers 12 months, with an extended 7-year warranty for core components including belts and motors. 24/7 technical support is available via a dedicated hotline to address operational issues and minimize downtime for production facilities. Operational data from existing clients shows a 20% reduction in product waste and a 15% increase in packaging efficiency due to uniform product sizing after freezing.
The standard 3-tier configuration delivers a maximum throughput of 1,000 kg/h. For facilities requiring higher output, the 5-tier upgrade supports a maximum throughput of 1,500 kg/h, with no increase in the equipment’s footprint width.
The freezer is equipped with a fully automated CIP cleaning system with 360° rotating spray nozzles, detergent dosing, and 85°C hot water rinsing to eliminate bacterial biofilms. It complies with ISO 22000 food safety management standards, and holds CE, UL, and CSA certifications for global market access.
Yes, the unit is designed for seamless integration into automated food processing lines, supporting connection with upstream pre-processing equipment and downstream packaging systems. Custom engineering services are available to match specific line configurations and auxiliary equipment setups.
