Gases to transport food
Liquid nitrogen and dry ice are used to keep food cool during transport
Sudden temperature changes can alter the state of food and cause the spread of germs and bacteria that diminish its quality. Therefore, it is paramount to keep food at adequate temperatures during transport.
OXIGEN salud supplies gases to transport food, such as liquid nitrogen or dry ice pellets (solid CO2). Both gases are used to transport fresh and frozen foods safely and at a controlled temperature.
There are different-sized cryogenic containers available with space for 5, 15, and 20 kg of pellets, and the possibility to distribute the exact amount requested by the client.
The following table provides an approximate indication of the amount of dry ice needed to transport frozen products:
| Weight of frozen product | Recommended dry ice weight for transit time | |||||
|---|---|---|---|---|---|---|
| 4 hours | 12 hours | 24 hours | 2 days | 3 days | 4 days | |
| 0,4 kg | 0,8 kg | 1,6 kg | 2,4 kg | 4,8 kg | 7,2 kg | 9,6 kg |
| 2,4 kg | >1,2 kg | 2 kg | 3,2 kg | 6 kg | 9,6 kg | 12,8 kg |
| 4 kg | 1,6 kg | 2,4 kg | 4 kg | 7,2 kg | 12 kg | 16 kg |
| 8 kg | 2 kg | 3,2 kg | 6 kg | 12 kg | 18 kg | 24 kg |
| 20 kg | 4 kg | 8 kg | 16 kg | 30 kg | 48 kg | 64 kg |
Common applications of refrigerated transport with gases
The use of liquid nitrogen and dry ice is key in sectors where the cold chain must be maintained without interruption. Some of the products most frequently transported using these systems are:
- Fresh or frozen fish, seafood, and meat.
- Dairy products and derivatives.
- Fruits and vegetables requiring specific preservation.
- Pastries, ice cream, and deep-frozen products. .
- Prepared meals for institutional and catering services.
These gases ensure active cooling, especially useful on long routes or when a mechanical refrigeration system is not available during transport.
At OXIGEN salud, we not only distribute gases for refrigerated food transport, but we also offer technical advice, training in safe handling, and a service tailored to each client, whether they are a food company, logistics firm, catering company, or restaurant business.
