Product overview
Continuous IQF Tunnel Freezer is a production-line freezing system that rapidly and individually freezes food items by circulating ultra-low-temperature forced air. It is engineered for integration into existing lines and for scalable medium to large production capacities.

Suitable for

• Chicken nuggets
• Burger patties
• Fish fillets
• Seafood
• Meat products
• Frozen vegetables
• Fruits
• Pizza
• Ready meals
• Bakery products

Designed for Industrial Production

• Continuous operation compatible with high-throughput lines
• Easy mechanical and control integration
• Adjustable freezing time and airflow settings
• Suitable for medium and large capacities
• Energy-efficient refrigeration system
• Stainless steel hygienic construction for food safety
• Accessible design for cleaning and maintenance
• Customisable layout to match factory footprint

How it works
Feeding → Stainless steel conveyor → Belt cold air circulation → Rapid freezing (-35°C to -45°C) → Discharge

Comparison (Traditional Freezing vs IQF Tunnel Freezer)

• Traditional freezing: Slow freezing — IQF Tunnel Freezer: Rapid freezing
• Traditional freezing: Large ice crystals — IQF: Small ice crystals
• Traditional freezing: Product lumps together — IQF: Individual freezing
• Traditional freezing: Texture damage — IQF: Better texture retention
• Traditional freezing: Higher moisture loss — IQF: Better moisture retention
• Traditional freezing: Lower product value — IQF: Higher product quality
