    How It Works

    You might wonder how a cryogenic tunnel freezer gets food so cold so fast. This freezer uses liquid nitrogen, which has a temperature of -196°C. When you place food inside, the liquid nitrogen flows over and around it. The extreme cold pulls heat out of the food almost instantly. You see frost form right away. The food freezes from the outside in, locking in moisture and nutrients. This method works well for foods that need gentle handling.

    Did you know? Liquid nitrogen is safe for food. It turns into gas and leaves no residue behind.

    Speed and Efficiency

    If you want speed, cryogenic freezing is hard to beat. Most foods freeze in seconds or just a few minutes. This quick process helps keep the food’s texture and taste. Modern cryogenic freezers use smart controls to save energy. They adjust the flow of liquid nitrogen so you don’t waste any. Some models even recycle cold air to lower costs. You get fast results and better energy use at the same time.

    Mechanical Tunnel Freezer

    Operation

    Mechanical tunnel freezers are common in food factories. They use cold air and strong cooling systems to freeze food. Food goes on a moving belt inside the freezer. Cold air blows over the food from every side. Powerful fans and coils with refrigerant make the air cold. The system keeps the temperature steady all the time. This gives even freezing from beginning to end. These freezers work well for chicken, vegetables, and burgers.

    Tip: Mechanical tunnel freezers can freeze big batches at once.

    Freezing Performance

    Mechanical tunnel freezers are slower than cryogenic models. You might wait minutes or hours for food to freeze. The speed depends on the food’s size and type. Thicker foods take more time to freeze. Still, you get good results every time. Newer models have better insulation and smart controls. These features help save energy and lower costs. You can change the temperature and airflow for your needs.
