IQF tunnel freezing for seafood, fish, poultry, and meat

Tunnel Freezer

The tunnel freezer is a high-efficiency, continuous freezing system with a simple and robust structure. It is available in two configurations: stainless-steel solid belt and mesh belt.

Advanced Freezing Technology

• Vertical airflow design ensures uniform air distribution

• Consistent and rapid freezing of both surface and core

• Efficient heat exchange for high product quality

Working Principle

Products are conveyed into the freezing zone, where high-speed axial fans blow cold air vertically through the evaporator and evenly across the product surface. After passing through the tunnel, frozen products are smoothly discharged while maintaining shape and texture.

Applications

Suitable for a wide range of foods, including:
Seafood, fish, shellfish, shrimp, meat, poultry, vegetables, fruits, and pastries.
