IQF refrigeration system is specialized for frozen products in bulk. The moving speed of the conveyor belt can be adjusted, this also depends on the frozen product as well as the requirements of the finished product. The heat in contact with the frozen product is high-speed forced convection air, the temperature is only from -35 to -43 degrees Celsius with a fast time, low heat loss thanks to the double-layer stainless steel insulation chamber made of poyurethane.
1. Concept of IQF refrigeration system
IQF refrigeration system is also known as the system of super-fast freezing of loose products. The symbol IQF is the English abbreviation of Individual Quickly Freezer. This system uses conveyor belts moving at slow speed. During the moving process, the products that need to be frozen will be exposed to cold air with gradually lower temperatures.

IQF refrigeration system classification has three main types as follows:
– Spiral conveyor freezer, also known as Spiral IQF
– Straight IQF conveyor freezer
– Super fast conveyor freezer: Impingement IQF
In the workshop or factory, the IQF refrigeration system chamber is combined with other conveyors such as steaming, cooling, drying, glazing conveyors and refreezing chambers.
2. Application
IQF (Individual Quickly Freezer) refrigeration system is also known as super fast freezing system for loose products.
There are types of IQF such as: IQF for freezing shrimp, unshaped seafood uses Net Belt made of stainless steel or PVC; IQF for shaped seafood, or meat uses Plate Belt made of stainless steel; IQF for vegetables, fruits, and agricultural products uses Fluid tunnel.

3. Technical specifications
This system has evaporator temperature: -40 degrees C to -45 degrees C, so it must use a 2-stage compressor, screw or piston.

Frequently asked questions about IQF refrigeration systems
What is an IQF refrigeration system for?
Fast freezing of individual pieces rather than in a block, so the product does not stick together and keeps a texture and colour close to the original after thawing.
What does an IQF refrigeration system consist of?
A freezing chamber with the belt, evaporators and high-velocity fans inside, plus the compressor pack, condenser and refrigerant pipework outside, together with the control panel.
Which products suit IQF?
Loose products of fairly uniform size — shrimp, fish fillets, squid, meat portions, cut vegetables, fruit — where freezing each piece separately adds clear commercial value.
What should be considered when investing in IQF?
The throughput actually required, the type and size of the product, the floor area and headroom available, the cooling capacity already on site, and the plant team’s ability to operate and maintain it.
Does Tân Long deliver IQF systems?
Yes. Tân Long designs and installs IQF freezing systems matched to the central refrigeration system, to the throughput and product type of each plant.
