Tunnel Freezer

Compare linear impingement, fluidized bed, and carton tunnel freezers for continuous inline production. Review airflow design, dwell time, and tunnel length for your plant.

Uniform Airflow

Precision air plenums and nozzle plates spread cold air evenly across the full belt width, giving every piece the same core exit temperature.

Smart Recipe Controls

The PLC touchscreen stores recipes for belt speed, fan speed, and zone temperatures so operators can switch products in minutes.

Cleaning Coverage

Full height side doors, welded sloped stainless steel drain pans, and optional automated CIP spray headers speed up shift washdowns.

How do I choose the right tunnel freezer capacity for my plant?

Sizing starts with four numbers: product thickness, hourly capacity (kg/h), inlet temperature, and target core exit temperature (usually −18°C). From these, our engineers calculate dwell time, belt area, and cooling load.

Can one tunnel freezer handle different products and recipes?

Yes. One tunnel freezer can run multiple products using variable belt speed and fan control. Operators simply pick the saved recipe on the touchscreen and run a CIP wash between product runs.
