Industrial IQF Freezers & Integrated Processing Lines

Q: What is an IQF freezer and how is it different from a normal tunnel freezer?

An individually quick-frozen (IQF) system is engineered to freeze each piece of food separately so particles remain free-flowing rather than freezing together in a solid block. It achieves this through rapid crust-freezing using high-velocity vertical air jets, upward fluidization, or high-tier-velocity spiral airflow.

Explore individual quick freezing (IQF) systems that freeze small, portioned, and delicate foods as separate pieces. Compare fluidized bed, impingement, and spiral IQF freezers below.

Intelligent Control for Precision Freezing

Square IQF freezers combine cold high velocity airflow (−35°C to −42°C) with gentle conveyor motion to freeze a surface crust in seconds. This locks in moisture and keeps pieces separate. A Siemens PLC touchscreen stores up to 50 product recipes.

Superior Energy Efficiency

Variable speed VFD fans, smooth air ducts, and hydraulically expanded coils deliver more cooling per kilowatt of power, cutting electricity cost per ton of product.

Certified Hygienic Design

Built with SUS304 stainless steel interiors, welded sloped drain floors, and open frames with no dirt traps, our IQF freezers meet strict HACCP and FDA hygiene rules.

Customized Engineering Solutions

Our engineers calculate dwell time, belt loading, and cooling load for your product, matching the freezer, coil, and ammonia or CO2 compressor skid as one complete system.

From inlet shakers and precoolers to downstream glazing and packing conveyors, we build complete IQF lines that protect product yield.

What is an IQF freezer and how is it different from a normal tunnel freezer?

An IQF freezer freezes each food piece separately so items stay loose and free flowing instead of clumping into a solid block. It uses fast vertical air jets, upward fluidization, or spiral airflow to set the surface crust quickly.

How do I choose between a fluidized bed IQF freezer and an IQF tunnel freezer?

Select a Fluidized Bed IQF Freezer for small, free-flowing particles such as green peas, corn kernels, berries, diced meat, and peeled shrimp that can be suspended in an upward air cushion. Select an Impingement Tunnel Freezer for thin, flat products (burger patties, fish fillets) requiring rapid crust freezing, or a Spiral IQF Freezer for larger portions, coated poultry, and bakery items requiring longer dwell times in a compact footprint.
