Freezing Tunnels – Efficient and Rapid Freezing Solution
Coldex offers high-quality freezing tunnels for the needs of the food industry and other sectors. Our tunnels are designed for fast and energy-efficient freezing, preserving product quality and freshness throughout the process.
What is a freezing tunnel?
A freezing tunnel is an industrial freezing system that enables fast and uniform freezing of products. It is based on efficient air circulation and precisely controlled temperatures to ensure the products reach the desired freezing level in the shortest possible time.
This process minimizes ice crystal damage and preserves the product’s texture, taste, and nutritional value. Freezing tunnels are widely used in the food industry as they ensure product safety and quality throughout the supply chain.
How does a freezing tunnel work?
1. Pre-cooling
The product enters the freezing tunnel and begins to cool rapidly through pre-cooling.
2. Intensive freezing
Powerful circulating cold air removes heat from the product extremely efficiently.
3. Final freezing
The product reaches the desired freezing level, such as -18°C or even -40°C.
4. Output to production line
The frozen product moves on for further processing, such as packaging or storage.
