A supply chain encompasses all the phases in the creation and distribution of a particular product. The chain traces the product from its origin as a raw material to its ultimate placement in a store or storage facility. International supply chains have become a norm in numerous sectors over the preceding 30 years. In such systems, the conceptualization, promotion, and sales activities predominantly occur in the affluent economies of Europe, North America, and Asia, whereas the actual production largely takes place in 'developing' nations across Asia, Africa, and the Americas. The links in the supply 'chain' are the consecutive steps starting from the cultivation or extraction of raw materials (like cotton, metal, oil, etc.) and culminating in the sale of the end products to consumers by the dominant company in the supply chain, often termed the 'lead' company. Regional value chains are also seeing increased significance, especially in places like South America and Africa, with countries like Chile or Brazil exporting agricultural goods to their neighbours.
A conventional global supply chain is intricate and multi-tiered and engages a diverse array of organizations, suppliers, and stakeholders.
For instance, clothing supply chains are frequently perceived as straightforward, but they are more complex in reality. In sectors like clothing, the primary companies – occasionally labelled as 'brands' – don't possess any manufacturing plants. These lead companies 'outsource' the entire production to standalone factories. They might switch suppliers from one factory to another every season, seeking more competitive rates or unique expertise. If lace attire is trendy one season and denim the subsequent one, brands might source from a lace-producing factory one season and a denim one the next.
Even though globalization has diminished the relative distance between global regions, the actual geographical separation remains crucial. The larger the geographical gap, the higher the chance of cargo getting harmed during one of the intricate transportation stages. Some items might be affected by jolts, while others might be harmed by excessive temperature fluctuations. For a category of goods termed perishables, especially food items, their quality deteriorates over time due to ongoing chemical reactions, the pace of which can be largely reduced with cooler temperatures. Efficiently moving a consignment takes time and coordination, and any holdups can lead to adverse outcomes, especially if the cargo is perishable. To guarantee that cargo remains intact throughout this journey, sectors like pharmaceuticals, healthcare, and food are increasingly leaning on the cold chain.
The cold chain pertains to the conveyance of temperature-sensitive items along a supply chain using thermal and cooled packaging techniques and logistical strategies to safeguard these consignments' integrity. Various methods exist for transporting cold chain goods, including cooled trucks and trains, refrigerated ships, reefers, and air freight.
Some local or cross-border supply chains might rely on a single mode of transport, but often, land shipments are just one part of a mix of transportation methods. This makes the transition between modes pivotal for the cold chain. Intermodal consignments usually employ 40-foot cooled containers capable of accommodating up to 26 tons of food. These containers streamline the loading and unloading durations, reducing potential harm to both the container and its contents. The conditions inside these containers are electronically regulated, either by connecting to a generator or power source on the vessel, truck, or terminals and distribution hubs. The proficiency of cold chain logistics has enabled the merging of cold storage facilities to cater to expansive market zones.
Transporting a consignment through the supply chain without any hitches or temperature deviations demands a thorough logistical procedure to uphold the consignment's integrity. This procedure encompasses various stages, from the consignment's preparation to the final inspection of its integrity at the delivery endpoint - including consignment preparation, mode selection, customs protocols, the last leg, and quality checks.
Once the consignment is delivered, any temperature recording instruments or detected temperature deviations must be documented and disclosed. This phase of the logistical procedure fosters trust and responsibility, especially if there's accountability for a compromised consignment. If issues or deviations that jeopardize a consignment arise, efforts should be made to pinpoint the cause and implement corrective measures. This is especially pertinent given the high worth of cold chain items. While a regular container load might be valued between $50,000 and $100,000, a refrigerated load's value can soar to $1 million. In the pharmaceutical domain, the cargo's value can skyrocket to $50 million.
Until today, reefer monitoring was either done manually or with the help of automated systems at container terminals. Some containers have built-in modems yet only deliver a small subset of monitoring data once per 24 hours. But for a forwarding company, owners of river barges, and managers of a train company, these technical solutions are just not good enough.
What is needed is complete reefer monitoring everywhere and at any time. Successful reefer management is all about visibility and real-time alarms to avoid mishaps that cost money and reduce efficiency, but most importantly, they assure integrity and quality of the cargo.
A successful solution to this challenge needs remote and mobile monitoring of temperature and other reefer data, including the location of the refrigerated container, super-easy deployment of the monitoring and tracking device, free of any other installations, and no manual interaction to access the data.
Independently of a reefer type, Reefer Runner 5G will upgrade them instantly to being "smart". It gives the operations manager full remote visibility of reefers out of the box. The reefer data becomes accessible everywhere through a web browser, including the current position of the reefer. Eventually, you need only one system for all reefer tasks in the cold chain. If the reefer is outside of any 5G connection, Reefer Runner 5G is caching offline data for later to synchronize it with the central cloud-based database.
One of the main advantages of reefer monitoring solutions like Reefer Runner 5G is that no installation is required at all. They simply connect to the data port, and they collect and transmit data. The low installation effort makes Reefer Runner 5G as easy to implement as it is powerful - out-of-the-box deployment means plugging it into the data port, and all necessary monitoring data becomes visible.
Cold chain tracking with solutions like Reefer Runner 5G not only give you all the reefer data that is needed to ensure a safe voyage, but they also give you a real-time overview of where all reefers are located, implicating that ETA can be adapted and customers can be informed much more precisely and in advance. It's important for the receiver of the shipment to have everything ready to park, plug and clear the refrigerated containers at their own premises.
What is cold chain tracking?
Cold chain tracking refers to the monitoring and recording of temperature-sensitive products as they move through the supply chain. This ensures that the products, often perishables like food and pharmaceuticals, are stored and transported within specified temperature ranges to maintain their quality and safety. Tracking systems typically use sensors and data loggers to continuously monitor temperature and other environmental conditions, sending alerts if there are deviations from the set parameters.
Why is cold chain tracking important?
Cold chain tracking is crucial for several reasons:
How does cold chain tracking technology work?
Cold chain tracking technology typically involves a combination of the following components:
By integrating these components, cold chain tracking technology provides a comprehensive view of the product's environment throughout its journey, ensuring it remains within safe and optimal conditions.
Cold chain tracking is an essential aspect of modern supply chain management, especially for temperature-sensitive products like pharmaceuticals and certain food items. It ensures that these products are consistently stored and transported within their specified temperature ranges, guaranteeing their quality, safety, and efficacy. The technology behind cold chain tracking typically combines temperature sensors or data loggers, advanced connectivity solutions, and a centralized monitoring system. This integration offers real-time visibility into the conditions of shipments, generating alerts for any deviations and producing reports for both analysis and regulatory compliance. As global trade continues to expand and regulations become even more stringent, the importance of cold chain tracking will only grow. It not only ensures product safety and compliance but also significantly reduces the risk of spoilage and waste, leading to both economic and environmental benefits. Reefer Runner 5G is an interesting option for reefer monitoring and tracking in the intermodal cold chain.
