IQF tunnel freezers, also known as quick freezer machines, are widely used in frozen French fries production lines as well as other frozen vegetable and fruit processing lines. IQF technology ensures that foods such as fruits, French fries, vegetables, seafood, and diced or sliced meats retain their shape, colour, flavour and texture by freezing them piece by piece. In a frozen French fries production plant, the IQF tunnel freezer is usually located between the chiller and the packaging machine.
Our tunnel freezer is a high tech design that effectively and efficiently freezes fries to -38°C quickly. It not only maintains the freshness and quality of the product, but also facilitates storage and transport, making it the ideal solution for your frozen food processing line. We can configure the french fries freezing machine according to your needs and requirements. For more information, please feel free to contact us.

Tunnel Freezing Process
The IQF tunnel freezer is designed with a modular structure combined with a highly efficient freezing system to ensure that products are frozen quickly and in a short period of time. Materials such as Chips enter the machine on a conveyor belt, first passing through an infeed area and then being gently dispersed by a vibrating device to prevent stacking and ensure that each product is cooled evenly. The conveyor belt can be cleaned during operation to maintain hygiene.
In the freezing channel, an axial fan circulates the cold air powerfully and rapidly reduces the temperature to below -30°C through the built-in evaporator, achieving rapid cooling of the material. The product can finally reach a freezing effect of -18°C. The whole conveying and freezing process is carried out in a sealed stainless steel cabinet, and the body shell adopts polyurethane adiabatic layer, effectively blocking the exchange of heat and cold and improving energy efficiency. The conveyor system is made of FDA-approved materials, which ensures food safety and extends the life of the equipment.
This process makes the IQF tunnel freezer a reliable and efficient quick-freezing solution for French fries processing plants.
Benefits of Quick Freezer Machine
- Superior Quality Preservation: Our tunnel freezers freeze a wide range of fruits and vegetables, cuts of meat and seafood and retain their taste, flavour and nutritional value. The rapid freezing process prevents the formation of large ice crystals and avoids damaging the cellular structure of the seafood.
- Extended Shelf Life: IQF freezing temperatures extend the shelf life of products without compromising their freshness. This means that products such as French fries can be stored for longer periods of time while maintaining their optimum quality.
- Efficient and Economical: For businesses, time is money. The IQF process significantly reduces freezing times compared to traditional methods, making it more efficient and cost-effective for mass French fries production line.
- Custom Design: Our IQF tunnel freezers can be configured with power, voltage and frequency customized to your needs.
- Durability: The overall structure of our plate freezers is made of high-quality stainless steel, which makes the machines robust and corrosion-resistant for long periods of time.

How is LONKIA IQF Tunnel Freezer Different Of Others?
As an experienced manufacturer of IQF tunnel freezers, we have always endeavoured to understand the complexities of the freezing process, and with a focus on efficiency and quality, LONKIA freezers have a range of unique features that significantly enhance the freezing process, ensuring that the end product not only retains its superior quality, but is also processed safely and efficiently.
1. Unique Aerodynamic Design
LONKIA quick freezer machines feature an independently optimised aerodynamic structure, which provides a more even distribution of cold air, effectively reducing dead spots and improving overall freezing efficiency. At the same time, the freezer is equipped with an adjustable fan, which can precisely control the air speed to adapt to a wide range of products from delicate vegetables to tough meats.
2. Replaceable Base Plate Design
The removable base plate at the bottom of the machine makes it easy to replace and clean, which is especially suitable for scenarios where products need to be replaced frequently or where high hygiene is required. This design greatly shortens the maintenance time and reduces labour costs.
3. Simple Installation and Transport
LONKIA IQF Tunnel Freezer supports split transport and modular assembly on site, and can also be transported efficiently by common truck or container ship. This simplified transport process reduces costs and ensures faster installation upon arrival.
4. Small Footprint
While maintaining productivity, LONKIA french fries freezing machine is compact and space-saving, allowing even small and medium-sized frozen food processors to enjoy the benefits of high-performance quick-freezing equipment.
