IQF Tunnel Freezers
Our IQF tunnel freezer quickly freezes your shrimp and other small, delicate products.
The Carsoe IQF tunnel freezer operates according to the vertical blowing principle. This tunnel freezer is designed for individual freezing of small products, such as shell-on shrimps and other delicate products.
It is worth noting that our IQF tunnel freezer is designed to form part of an automatic processing line, and therefore easy to implement into existing processing lines.
How does it work?
Tunnel freezing process
The product moves through the machine on a conveyor and is led past axial fans. The fans blow the air through an evaporator generating an air temperature of below -30°c.
A quick freezing with a product temperature down to -18°c is achieved with this IQF tunnel freezer.
The cabinet in the IQF freezer is made of modules with polyurethane insulation, ensuring that no hot air enters the freezer and no cold air gets out. The conveyor frame is made of stainless steel, whereas the belt is made of fda-approved materials.
The open IQF-design facilitates a cleaning that meets even the strictest veterinary demands.

Advantages of IQF tunnel freezer for seafood
- Superior quality preservation:
Using the IQF tunnel freezer, seafood, especially delicate items like shrimp, retains its texture, flavor, and nutritional value. The quick freeze process prevents the formation of large ice crystals, which can damage the cellular structure of the seafood.
- Increased shelf life:
IQF freezing temperature extends the shelf life of seafood products without compromising their freshness. This means seafood can be stored for longer periods while maintaining their peak quality.
- Efficiency and cost-effectiveness:
For businesses, time is money. The IQF process significantly reduces the freezing time compared to traditional methods, making it more efficient and cost-effective for large-scale operations.

FAQs
What is the difference between IQF and blast freezing?
IQF (Individual Quick Freezing) focuses on freezing individual pieces of product separately from each other, ensuring that they don't stick together and preserving their individual shapes and nutritional content. Blast freezing, on the other hand, rapidly reduces the temperature of a bulk product, often resulting in clumped-together items.
What is the principle of IQF freezing?
The primary principle behind IQF freezing is to quickly freeze individual items separately at extremely low temperatures. This rapid freezing process prevents the formation of large ice crystals, ensuring the product retains its original texture, shape, and nutritional value.
Is IQF considered fresh?
The IQF technique preserves a product's freshness, flavor, and nutrition more effectively than standard freezing. As a result, IQF-frozen items often mirror the quality of fresh products.
