The journey for temperature-controlled products often comes with endless challenges. Here is a handy overview of potential risks and how data logging can enhance cold chain monitoring during transport.
- Transport type, terrain, and the external and internal environment are all critical factors in moving products successfully from point A to point B
- Temperature impact and CO2 excursions occur under certain conditions
- Digital data loggers that capture multiple metrics reduce cold-chain transportation complications
If you run a food and agriculture business or a company that handles perishable goods, you understand that a slight temperature shift can mean a substantial financial loss due to pathogen formation. That’s why cold chain monitoring during transport is so important. By understanding the ins and outs of monitoring your goods in transit, you can ensure that your product will arrive fresh and intact as intended.
But some factors can affect product quality from the point of distribution to consumers. Here we guide you through these factors in detail, with solutions to optimize efficiency and ensure spoilage is nonexistent.
Modes of transport
Depending on the distance and the kind of product being transported, you may choose to use different modes of transport. Regardless of using a plane, ship, or truck, each option presents specific complications.
- Air: Despite the benefits of air transport in the cold chain, it is often associated with costly shortcomings. The formation of ice crystals due to dry air inside an aircraft can damage products in minutes. These ice crystals usually form when the outside air temperature is lower than the internal cabin temperature at high altitudes or in humid conditions. In the event of flight delays due to bad weather, the consequences can be grave.
- Water: Water transport is another option used for cold chain products, but it is also imperfect. When combined with saltwater spray and solar radiation, humidity levels in the water can damage most products. Also, ships may take longer to reach their destination than other transportation modes, increasing the risk of damage.
- Road: While road transport is the most common and cost-efficient way to move products from one place to another, unpredictable weather conditions or poorly insulated vehicles can cause dry ice and condensation, leading to thermal or physical damage to goods.
Now that we’ve covered transportation methods, let’s look more closely at terrain and its impacts on road transportation.
Terrain and its impacts
The terrain also presents challenges for maintaining cold chain temperature and ensuring product integrity. These include ascending and descending steep inclines, navigating winding paths, or crossing mountainous regions.
Ascending and descending hills causes air pressure to fluctuate rapidly, leading to humidity and temperature changes. This is especially true if a vehicle fails to maintain a consistent speed during travel.
Winding paths can cause drastic changes in airflow patterns inside the vehicle, leading to thermal excursions and condensation. In addition, mountainous regions present challenges, especially if the road includes long tunnels. Some routes may be long and bumpy, increasing time spent on the road. These possibilities increase the chance of temperature fluctuations, leading to degraded product quality.
External and internal environment complications
The external climate and weather conditions affect how quickly the vehicle’s interior warms up or cools down. If it’s too hot outside, the vehicle’s interior can get much warmer than anticipated, leading to product degradation.
On the other hand, if the external air is colder than inside the vehicle, condensation can form around products or containers and lead to product damage. The internal environment of a vehicle also impacts its insulation, the type of packaging and cargo, and its loading configuration.
CO2 and its implications
CO2 is an essential part of the cold chain process, as it helps maintain product integrity from the point of production to the consumers. However, maintaining high CO2 levels and low oxygen levels in low temperatures can be challenging.
Several factors may cause changes in CO2 levels during the transport process, including high temperatures and humidity or a breakdown of the cold chain. For example, ascending a mountain causes the CO2 levels to drop as you gain altitude. If the CO2 levels in the cold chain are not maintained correctly during transport, it can affect product quality.
