Cold chain logistics ensures the quality of transported goods by maintaining controlled temperatures throughout the shipping process. If you’re considering cold chain transportation for your agricultural products, seafood, pharmaceuticals, or other temperature-sensitive goods, this article may offer valuable insights.
1. What Is Cold Chain Logistics?
Cold chain logistics (refrigerated chain materials) refers to the transportation of products through controlled temperature management. The entire cold chain process encompasses more than just transportation—from packaging and storage to delivery to the end customer, temperatures must be maintained consistently within a specific range to prevent any damage to temperature-sensitive goods.
Professional cold chain logistics requires proper packaging, appropriate storage methods, specialized transport equipment, optimized transportation routes, and corresponding monitoring and contingency strategies to ensure goods reach customers safely and efficiently.
1.1 What Products Require Cold Chain Logistics?
The demand for agricultural products, fruits, and similar goods continues to grow, with quality standards steadily rising. For regions where production volumes are low or natural conditions are unsuitable, importation presents a viable alternative.
For medical pharmaceuticals, technological barriers further compel certain countries and regions to rely on shipments from elsewhere to meet local populations’ needs.
Whether transporting agricultural goods, agricultural products,beverage, seafood, or medical pharmaceuticals, maintaining precise temperature control throughout transit is critical. Improper temperatures can irreparably damage products, leading to inevitable losses. Thus, cold chain logistics is absolutely essential.
1.1.1 Pharmaceutical Products in Cold Chain Logistics
Different types of pharmaceutical products require varying temperatures during cold chain logistics.Pharmaceutical products necessitate extremely stringent cold chain temperature control to ensure patient safety.
A controlled room temperature of 15°C to 25°C is suitable for transporting non-sterile pharmaceuticals. A refrigerated temperature of 2°C to 8°C is appropriate for transporting specialty medications, vaccines, insulin, and similar products. Plasma, tissues, vaccines, and other items require transport at a frozen temperature of -15°C to -25°C.
1.1.2 Agricultural Products in Cold Chain Logistics
Agricultural products are also known as perishable goods because they undergo chemical reactions with temperature changes, causing their quality to deteriorate over time. Lowering temperatures can slow down this reaction rate.
Different types of agricultural products require varying cold chain transport temperatures. Leafy vegetables like lettuce and spinach need to be maintained between 0°C and 4°C to effectively delay moisture evaporation. Root vegetables, however, should be maintained between 4°C and 10°C, as lower temperatures can affect their texture.
Most common fruits only need temperatures between 0°C and 4°C, while tropical fruits like bananas, mangoes, and papayas require temperatures between 10°C and 13°C to prevent cold damage.
1.1.3 Seafood Products in Cold Chain Logistics
Seafood must maintain an unbroken cold chain throughout transportation, with no temperature fluctuations. For live seafood, the primary focus is on constant temperature, humidity retention, and oxygen supply. For frozen seafood, the key lies in sustained low temperatures. Different types of seafood require corresponding cold chain temperatures.
Live seafood (such as shellfish, crabs, and lobsters) requires transportation at 0°C to 4°C within the cold chain, while maintaining humidity and oxygen supply to prolong viability. Frozen seafood (such as frozen fish, shrimp, squid, etc.) must be maintained below -18°C to ensure stable quality. Deep-frozen seafood (high-value fish like tuna) typically requires transport at ultra-low temperatures between -40°C and -60°C to maximize preservation of meat texture and flavor.
