Túnel de congelación IQF lineal, sistema aire forzado.
It is a new generation ultra-freezing equipment developed by the engineers of PALINOX INGENIERÍA Y PROYECTOS S.L. to achieve greater efficiency and effectiveness of the rapid freezing processes.

A linear and compact tunnel equipped with new technologies manufactured with highly resistant materials to the environmental agents found in the process rooms.

Ergonomic, easy to install and operate with essential operating features that we detail below:


One of the particularities, among others of great importance, is the air flow. Our channeling system allows you to get the most out of the product, creating a closed circuit and forcing the air to rub the top and bottom smoothly and intelligently. This causes the product to accelerate its freezing process and the temperature to act faster, reaching the heart of the piece earlier.
Our technical department has many years of experience so it has managed to incorporate properly a large evaporator with a train of perfectly calculated fans in the different models, thus providing the necessary air flow and pressure and ensuring its full efficiency.


In the different models for linear tunnel freezing, two completely independent conveyors are incorporated with the option to work at different speeds.

These conveyors are equipped with a lifting mechanism that allows the first section to rise in height automatically, thus avoiding the formation of compact groups when introducing the fresh product, often with excessive humidity and mainly in light weight products. The separation between pieces is vital to avoid wastage and optimizing the production performance. With our intelligent conveyor system we regulate the speed of the first section until the product exceeds the freezing point, thus allowing the second section to be gathered without the compaction of the product being a problem.

On the lower end tier, and depending on the product, the speed is reduced until reaching the desired temperature. Both tiers are equipped with a centrifugal vibration system which keeps the product moving, which is useful for small-sized pieces. In the normal operating position (straight), the product can be frozen in boxes and IQF.


They are manufactured in four standard models for different productions ranges that comes from 300 to 1,000 kg / hour, with a meticulous study for each order and product.


It is designed for any food product which requires an IQF freezing process. Highly recognized in the fishing industry and proven with a high note for its performance in other sectors such as bakery, pastry and meat.


No work and quick to install. The engineers of PALINOX have achieved with this design a safe, practical and reliable equipment. We have taken into account the harsh working conditions and the low temperatures to which it is subjected, which is why it is sold in almost all our orders, compact and protected in an isothermal container, since there is no another better method to resist the changes of temperature, thus solving the problems by bumps and cracks in the ground and gaining a high power of isolation and saving energy losses.


They are designed to work with all existing refrige-rants in the market, (Freon, Ammonia and Co2).

The evaporators that are incorporated are stainless steel with stainless aluminum fin.

Customized powers are calculated for each one of the needs. It is necessary to add the air channeling system to the freezing efficiency, leading it to the belt where the product is.

A homogeneous friction of the air in all its perimeter allows to obtain an optimum performance avoiding costly dehydration losses.


The isothermal chamber is crucial for the savings and durability of these equipment. It is manufactured with new generation materials forming a monoblock. The floor inside is hardened and reinforced with epoxy resins granulated with quartz sand.


PALINOX engineers are aware of the adversities that processors have to go through, and of the dependence that many companies have on these equipment, mainly in the fishing and meat sectors with perishable products, and more so if the plants are located in zones where spare parts and qualified personnel are scarce.
For this reason, we only use standard materials and recognized brands, taking care that they are present in all cities and countries of the world. Incorporating only thermal protections with great resistance to water (IP-67), it has diffusers for daily internal cleaning of the tapes, and on request, a group with a pressure pump can be incorporated, making disinfection even easier.

It is very easy to access inside and allows the entry of operators during the maintenance program.
Other benefits:
-Perfect for hostile environments with high levels of humidity.
-Easy access to daily cleaning.
-Simple preventive maintenance.
-All the securities required according to regulations.
