Cryogenic freezing of food products
Are you looking for a technique to better preserve the quality of your products, or to freeze fragile foods separately?
Cryogenic freezing offers you the opportunity to optimise your process, thanks to the cooling capacity and very low temperatures of cryogenic liquids.
- Flexibility of use for variable production
- Better product quality when defrosting
- Optimisationn of production speeds
Our cryogenic freezing solution for food products brings you:
|
|
Safeguard the freshness, texture and flavour of productsThanks to a very rapid drop in temperature at the core, cryogenic freezing ensures micro crystallization of water in the cells, preserving there integrity and the texture of food products. |
|
|
Flexibility and productivity gainsCryogenic equipment can adapt to any change in production, by adjusting the flow rate and the set temperature of the fluid. In addition, since water losses linked to dehydration are limited, your product yield is optimised. |
|
|
Space saving and ease of integrationAt power equivalent to conventional mechanical cold, cryogenic equipment is less bulky and can be adapted to many configurations. Simple in design, they are quickly operational and fit naturally into the existing production line. |
|
|
Optimised utilisation rateCryogenic equipment is mechanically very simple, without a compressor, which implies less maintenance, less defrosting. Easy and fast cleaning is due to the better accessibility. This reduces downtime. |

Cryogenic cold Vs mechanical cold
If mechanical refrigeration is a very widespread technology, cryogenic refrigeration offers many advantages, sometimes unrecognized, in terms of product quality, freezing speed, flexibility of installations. Air Liquide explains the advantages of cryogenic cold and the difference with mechanical cold.
