IQF Fluidized Bed Freezer 1000 kg/h

IQF Fluidized Bed Freezer

IQF fluidized bed freezer that individually quick-freezes small piece products such as diced vegetables, peas and berries without clumping.

How it works

Product is fed onto a perforated bed through which cold air is blown upward at a velocity that lifts and separates the pieces — the bed behaves like a fluid. Each piece is frozen individually while suspended, which prevents clumping. Belt speed and air temperature set the freezing time; the product leaves free-flowing.

Suitable for

Peas, diced carrot, sweetcorn, berries, diced fruit, shrimp-like small pieces — any small product that must stay free-flowing.

Not suitable for

Large or heavy pieces that cannot be fluidized; leafy products that mat; products requiring block freezing.

Material & compliance

Belt, bed and contact surfaces SUS304 (EN 1.4301); insulated stainless enclosure; contact welds Ra <= 0.8 um. Designed for washdown in a cold environment.

CE declaration and DoC; EN 10204 3.1 for contact parts; refrigerant handling per local regulation; hygienic design for frozen-food environments.

Selection notes

Freezing capacity is stated at a defined product and inlet temperature — always check the basis of the rating, because the same machine rates differently for peas versus diced carrot. Ask about refrigerant type and charge, since this affects both regulation and running cost. Check defrost method and how long it takes.

When you should not buy this machine: Do not buy a fluidized bed for product that cannot be fluidized (large, heavy or mat-forming) — it will freeze unevenly and you need a tunnel or spiral freezer. Also confirm your refrigeration plant can supply the load; the freezer is only part of the system.

FAQ

What does IQF mean in practice?

Each piece is frozen separately and leaves the freezer free-flowing, so the packer can portion it without thawing a block.

How is capacity rated?

At a defined product, size and inlet temperature. The same machine will rate differently for peas versus diced carrot, so ask for the rating basis.

Which refrigerant should I choose?

It depends on local regulation, plant size and service capability. Natural refrigerants such as ammonia, CO2 or propane reduce regulatory exposure but need appropriately skilled service.
