IQF Freezer FAQs
An IQF freezer (Individual Quick Freezing freezer) is designed so each piece of product freezes separately, without clumping. It uses controlled air velocity, temperature and belt motion to keep particles moving and apart, unlike conventional freezers where product can freeze together into blocks.
Fluidized bed IQF freezers are ideal for small, uniform particles like vegetables, berries and shrimp, especially when you need very high single-piece rates. Tunnel IQF freezers are better for larger, irregular products, coated or marinated items and mixed components. Your product mix, capacity and layout will determine the best choice.
Energy consumption depends on product, capacity, inlet temperature and plant conditions. Our IQF freezers are designed with high-efficiency evaporators, optimized airflow and intelligent controls to reduce kWh/kg compared to older systems. During the proposal phase we can estimate energy usage for your specific case.
For a standard IQF freezer line, on-site installation and commissioning typically takes a few weeks, depending on site readiness and integration with upstream and downstream equipment. We provide a detailed schedule as part of the project plan.
Yes. With adjustable belt speed, airflow and temperature settings, one IQF freezer can handle multiple products and recipes. For very different products (for example, leafy vegetables versus heavy coated items), we may recommend specific options such as different infeed systems or stirrer modules.
Our IQF freezers are built according to hygienic design principles, with easy access, stainless-steel construction and optional CIP and belt-washing systems. This helps you clean faster, reach all surfaces and comply with your HACCP and food safety requirements.
