Summary

The technology of cryogenic-ventilation freezing combines two different methods of deep-freezing of foodstuffs, i.e. rapid pre-freezing in liquid nitrogen or liquid carbon dioxide to a temperature of about -3°C, followed by freezing in a traditional ventilation tunnel until the temperature of deep-freeze storage is reached. From the technological perspective, this process assure a fast rate of freezing and increases economic effectiveness, since the traditional method employed at the later stage is relatively inexpensive. The application of this system on a large industrial scale may contribute to improving the freezing capacity and reducing the quantity of liquid gases used during the freezing process.
