What is a Tunnel Freezer?
A tunnel freezer is an industrial freezing machine designed to rapidly freeze products in a continuous, high-capacity system. With its tunnel-like structure and conveyor belt that carries products through controlled, ultra-low temperatures, this type of freezer is widely used in food processing industries to preserve items like seafood, vegetables, meats, and ready-to-eat meals. The quick freezing process helps maintain the texture, flavor, and nutritional content of the products.
How Does a Tunnel Freezer Work?
Tunnel freezers work by moving products through a chilling environment on a conveyor belt. This process often uses forced cold air or cryogenic gases, such as liquid nitrogen or carbon dioxide, to achieve extremely low temperatures quickly. Here’s an overview of the process:
Product Loading: Products are placed on a conveyor belt that moves them continuously through the freezing tunnel.
Rapid Cooling and Freezing: As products move through the tunnel, they are exposed to blasts of sub-zero air or cryogenic gases, which instantly freeze the outer layer. This step is crucial, as the rapid freezing locks in moisture, texture, and nutritional value.
Temperature Control: Tunnel freezers maintain precise temperature control, ensuring uniform freezing without damaging the product. Some systems can be adjusted to freeze different types of items at varying speeds.
Exit and Packaging: Once the freezing process is complete, products exit the tunnel and are ready for packaging and storage.
This efficient, high-speed freezing method is particularly suitable for food products, as it minimizes ice crystal formation and preserves cell integrity, resulting in high-quality, individually quick frozen (IQF) items.
