How to Choose a Fluidized Bed IQF Freezer for Your Product

Start with the product, not the machine size

A fluidized bed IQF freezer is selected around the product's shape, moisture, bulk density and target outlet temperature. Peas, diced vegetables, berries, sliced fruit and small seafood products can all use fluidized freezing, but the air velocity and residence time are different for every product.

The most useful first specification is a representative product sample together with the required hourly output. This gives the engineering team a better basis than capacity alone.

• Product type and piece size
• Inlet and outlet temperature
• Target capacity in kg/h
• Available factory space and utilities

Capacity and freezing time must be considered together

The SLD series is available in reference capacities from 500 kg/h to 3,000 kg/h. Actual throughput depends on the product and its water content. A larger belt or a longer freezing room does not automatically deliver the right result if the product layer and airflow are not matched.

During project confirmation, the freezing time, belt loading and refrigeration capacity should be reviewed as one process basis.

Build the upstream line around the freezer

Washing, blanching, cooling, dewatering and vibration distribution influence how evenly the product enters the freezer. For a vegetable or strawberry project, the freezer is usually only one part of a complete line.

A coordinated line reduces manual handling and gives the buyer a clearer basis for layout, quotation and future expansion.
