Freeze Fast to Preserve Original Quality

In industrial food processing, freezing speed is the key factor that determines the final quality of the thawed product. Freezing too slowly forms large ice crystals that rupture food cells, causing significant drip loss, a change in texture and lower nutritional value.
At Afric Froid, we design, manufacture and install tailored ultra-fast blast freezing tunnels. Our equipment takes products through the zone of maximum crystallisation in record time, forming micro-crystals that fully preserve freshness, colour and flavour.

Our Blast Freezing Tunnel Ranges

We offer freezing systems suited to your packaging methods, production rates and plant layout.

IQF Individual Quick Freezing Tunnels

Technology: Fluidised-bed or continuous belt freezing.

Applications: Shrimp, diced meat, berries (strawberries, raspberries), cut vegetables, sliced poultry, pasta.

Benefits: Prevents portions from sticking together (no block freezing), makes portioning for packing easy and freezes evenly in a few minutes.

Trolley / Static Blast Freezing Tunnels

Technology: Cells or longitudinal tunnels with high cold-air circulation (+30 to -40°C) that take trolleys or hanging racks.

Applications: Cartons of meat, whole poultry, whole fish, ready meals in trays, industrial pastries.

Benefits: Highly flexible operation, ideal for batch processing, with controlled investment costs.

Continuous Belt / Spiral Freezing Tunnels

Technology: Continuous linear or vertical spiral conveyor to make the most of floor space in production areas.

Applications: Minced steaks, nuggets, breaded escalopes, pizzas, pastries and frozen raw bakery products.

Benefits: Direct integration into automated production lines, perfectly consistent heat treatment and space savings.

Post-Cooking Rapid Chilling Cells & Tunnels

Technology: Accelerated cooling of ready meals and cooked meats leaving the ovens (from +70°C to +3°C core temperature in under 90 to 120 min).

Benefits: Strict food safety (rapid passage through the critical +10°C/+63°C zone) and limited water evaporation (product yield).

Afric Froid Technical Performance & Innovations

High-Pressure Airflow

Evaporators with high-pressure axial fans delivering high air velocity (up to 4 to 6 m/s) in direct contact with the product.

Continuous / Sequential Defrosting

Hot-gas or compressed-air defrost systems keep the tunnel running continuously without loss of cooling capacity.

Ultra-Hygienic Design

100% 304/316L stainless steel interior, floors that can be hosed down with drainage slopes, and liftable / Clean-in-Place (CIP) evaporators.

High Energy Efficiency

Reinforced polyurethane/polyisocyanurate (PIR) insulation 150 to 200 mm thick and electronic expansion valve control.
