Depuis 1968, Jean-Claude Comby, fondateur de la société ACFRI, développe une gamme de cellules de refroidissement rapide et de surgélation utilisant la technologie des évaporateurs à tubes verticaux.
This technology offers many advantages:
Le refroidissement est obtenu à très basses températures, sans
risk of products freezing too quickly.
La ventilation et la température étant homogènes sur la hauteur, les produits sur le haut du chariot atteignent la température cycle en même temps que ceux du bas.
Le principe du refroidissement rapide et de la surgélation en froid mécanique est basé sur la différence de température entre le produit et l’air soufflé. Plus l’écart de température sera important, plus le cycle sera court. En refroidissement rapide comme en surgélation , une cellule doit être capable de d’atteindre des températures de soufflage négatives.
To reach a core temperature of +10°C, some products need to be blown down to -20°C.
Some products that are more fragile and easier to cool may be satisfied with controlled blowing throughout the cycle (see ACFRI temp'progressif solution).
To quickly reach a core temperature of -18°C, all products require intense blowing between -30°C and -40°C.
The air speed allows the exchange of heat that is essential for the rapid cooling of a product.
The more a product is ventilated, the faster it cools. If rapid cooling is achieved by blowing cold air at sub-zero temperatures, it is essential to ensure that all products are blown in at the same rate, otherwise the first products to be cooled may freeze prematurely.
Some of the more demanding products require specific, highly ventilated cooling.
The use of perforated crates, pallets or particularly bulky trolleys is a barrier to the passage of air over the product. For these situations, ACFRI has developed a high-performance ventilation system.
Ventilation is provided by a double air circuit on each side of the trolleys.
This device can be combined with the system for reversing the ventilation direction during the cycle.
