What is an IQF freezer?

IQF stands for “Individually Quick Frozen”. The IQF freezers can easily freeze individual pieces of food. This freezing solution makes sure the individual seafood products do not clump together when the products are packaged after the freezing process.

IQF freezers can vary in size and capacity. This type of freezer can be customized to your requirements if you need a small IQF freezer or a large one. 

This freezer is especially well-suited for freezing batches of food products that tend to clump together when frozen. The food pieces will be frozen individually and separated within the batch. You will experience the great benefits of the IQF freezers when freezing batches of shellfish, shrimp, and other delicate seafood products.

For onboard freezing it can be beneficial to combine your IQF freezing line with a line of automatic horizontal plate freezers to allow for both block freezing and individually quick freezing of your catch.

The IQF freezing process


IQF freezers individually freeze food products via the cold air circulation method. Within the freezer the air is cooled down to an approximate temperature of -30 degrees.



The food passes through a freezing tunnel on a conveyor belt. The constant cold air flows through the tunnel in circular motions until the food is frozen at -18 degrees, when it reaches the exit of the tunnel.


This freezing method ensures quick freezing of your seafood products, thus preserving a high-quality product. By adding an IQF freezing tunnels to your seafood processing line you will gain a high production capacity.
