It may not have been easy to transport the Covid Vaccine from one country to another if proper storage facilities were unavailable. If the supply chain parties, such as carriers and storage facilities, had not properly managed the cold chain, those vaccines could have been spoiled. And we might see very serious consequences.
Not just vaccines, many food products, medicines, and other goods must also maintain a set temperature to be transported from one place to another. Otherwise, the chances of them getting spoiled increases. To maintain this proper temperature, cold chain management is required.
Companies like Zomato and Zepto rely heavily on dark stores and efficient food and grocery delivery logistics . These businesses benefit immensely from advanced cold chain solutions as they enable real-time monitoring, enhance operational efficiency, and ensure customer satisfaction.
In this blog, we will discuss cold chain management, its benefits and how changing technology is bringing about a new revolution in cold chain management.
What is Cold Supply Chain Management?
Cold supply chain management is a process by which temperature sensitive products are stored in a temperature controlled environment during transportation where their quality is maintained. These temperature sensitive products include certain foods, medicines, vaccines and chemicals. These products need to be stored at a set temperature. If that temperature is not maintained then there is a high chance that these products will spoil.
These products especially need to be taken care of during transportation. To maintain their freshness, effectiveness and safety, they need to be kept in a temperature controlled environment so that their quality does not deteriorate.
Here are the key components of cold chain management:
1. Temperature-Controlled Storage
In this, temperature sensitive products are kept in temperature-controlled conditions.
These storage areas are maintained at a set temperature so that the products do not spoil and their quality is maintained.
Types of Temperature-Controlled Storage Facilities
Cold Rooms: These are the storage areas or rooms where perishable goods are kept. This includes fruits, vegetables and dairy products.
Refrigerated Warehouses: Refrigerated warehouses are used for bulk storage.
Cryogenic Storage: This is where products that need to be maintained at ultra-low temperatures are stored. This includes pharmaceuticals or biological samples, such as vaccines.
Freezers: These items stored here that need to be maintained at sub-zero temperatures.
2. Temperature-Controlled Transport
When it comes to transporting goods, specialized vehicles and containers are used to maintain the quality of temperature sensitive goods. These vehicles and containers ensure the products are maintained at a specific temperature during transportation.
Modes of Transport include
Reefer Trucks: Reefer trucks are used to transport temperature sensitive products over long distances. These are a type of refrigerated trucks that maintain the required temperature. Whenever perishable goods such as food, medicines and agricultural products have to be transported while maintaining the required temperatures and humidity levels, reefer trucks act as the lifeline of cold chain logistics.
Refrigerated Rail Cars: These rail cards are used when large quantities of products are transported over long distances.
Refrigerated Containers: These containers are used when shipping is to be done for global trade.
Air Cargo: Air cargo is required when highly temperature sensitive products such as vaccines or fresh seafood need to be transported.
Technologies used
These require IoT sensors. These smart sensors monitor temperature, humidity, and vibrations and alert if the set values are below or above them. These require GPS trackers. These trackers provide real-time updates on the location and conditions of the shipment.
3. Packaging Solutions
Packaging plays a very important role in safe transportation. Better packaging can protect temperature sensitive products from getting spoiled in any condition. Packaging is the first line of defense to protect against external factors such as heat, moisture, and physical damage.
Common Packaging Materials:
Insulated Boxes: If the shipment is small, insulated boxes are very effective in maintaining cold temperature for short periods.
Gel Packs and Dry Ice: These packs and dry ice keep pharmaceuticals and frozen foods intact during transportation. They are capable of providing safety for a long time.
Vacuum-Sealed bags: These bags protect the products from air and moisture. These bags are used a lot in areas with moisture in the air.
Phase Change Materials (PCMs): These special materials release or absorb heat to maintain a constant temperature.
4. Monitoring and Tracking Systems
Smart monitoring and tracking systems are very important to maintain the quality of the product. These systems ensure that the products in the cold chain remain within the required temperature range. If there is even a slight deviation in the temperature, these systems alert. This can prevent the products from getting spoiled.
Technologies used:
IoT Sensors: These sensors are installed in storage units or vehicles so that temperature and humidity levels can be continuously maintained.
GPS Trackers: These trackers provide real-time updates about the location of the shipment. Its biggest advantage is that if a shipment is possibly late, they get it in advance. Due to this, delays can be prevented.
Cloud-Based Software: These software is very effective for logistic teams. They store the sensor’s data and provide it to the logistic teams so that decision making can be made by analyzing the data.
