The IQF freezing system is specialized for freezing individual products. The conveyor belt speed can be adjusted, depending on the freezing requirements and final product specifications. The contact heat with the frozen items is through high-speed forced convection air, with temperatures ranging from -35 to -43 degrees Celsius, for a short period, minimizing heat loss due to the double-layer insulated chamber wrapped in stainless steel made from polyurethane.
1. Concept of the IQF Freezing System
The IQF freezing system, also known as the super-fast freezing system for individual products. The abbreviation IQF stands for Individual Quickly Freezer. This system uses moving conveyors at slow speeds. During the movement, the products to be frozen come into contact with gradually decreasing cold air.

Classification of IQF Freezing Systems includes three main types:
– Spiral IQF, also known as Spiral IQF conveyor belt freezing chamber
– Straight IQF conveyor belt freezing chamber
– Impingement IQF conveyor belt super-fast freezing chamber
In factories or processing plants, the IQF freezing chamber is usually connected with other conveyor belts such as blanching, cooling, drying, coating, and thawing chambers.
2. Applications
IQF freezing system (Individual Quickly Freezer) or the super-fast freezing system for individual products.
There are different types of IQF systems such as: IQF for freezing shrimp, non-shaped seafood use stainless steel or PVC Net Belt; IQF for shaped seafood or meat use stainless steel Plate Belt; IQF for vegetables, roots, fruits, various agricultural products use Fluid tunnel type.
In factories or processing plants, the IQF freezing chamber is usually connected with other conveyor belts such as blanching, cooling, drying, coating, and thawing chambers.
