Cargo loss rates in durian transport have long run high. Spoiled flesh, temperature fluctuations, and mechanical damage — these three problems recur again and again. When a durian transport container falls short on temperature control or physical protection, post-voyage loss rates can reach 15% to 20%. Cargo loss falls into three main categories: chilling injury or freeze damage from temperature-control failure, mechanical damage from transport vibration, and husk cracking from humidity imbalance. The root causes differ, and so do the prevention approaches. Only by understanding the source of each problem can the right countermeasures be applied.

Temperature-control failure is one of the leading causes of cargo loss. Durian is sensitive to temperature, with an optimal range of 13 to 15 degrees Celsius. Below 10°C, the flesh suffers chilling injury, turning brown and firm. Above 18°C, ripening accelerates, and the flesh becomes soft and weeps moisture. When the refrigeration unit in a durian transport container fails, or when the door seal is compromised, temperature can quickly run out of control. The problem is most acute at transfer points: door-open inspections take time, large volumes of cold air escape, and rewarming happens quickly. On the prevention side, opt for refrigeration units with dual compressors — when one fails, the other automatically takes over. Door gaskets should use a three-layer silicone structure to minimize cold-air leakage. Temperature recorders upload data in real time, and the system triggers automatic alarms in the event of any anomaly.

The second category is mechanical damage. Durians have spiny shells and easily puncture neighboring fruit when stacked. Road drayage segments are heavily jolted, and if cargo is not securely fastened, durians roll and collide inside the container. Anti-slip flooring layers should be placed across the container bottom, with dividers separating individual fruit. Loading density should be capped at no more than 200 kg per cubic meter, leaving buffer space. In rail transport scenarios, the impact forces at carriage couplings are substantial, so the container twist-locks should be of reinforced specification to prevent displacement. A durian transport container must be structurally robust — floor loading capacity of no less than 2 tons, with sidewall deformation resistance meeting required standards.

Humidity imbalance is easily overlooked. When the durian husk loses moisture it cracks open, allowing bacterial intrusion and accelerating flesh spoilage. In-container humidity should be held between 85% and 90%. Traditional reefer containers tend to run on the dry side, and over long voyages husk moisture loss becomes pronounced. The solution is to install a water tray at the container floor, or fit an ultrasonic humidification module. Interior walls can be coated with an anti-condensation finish to reduce moisture adhesion. At transfer points, keep door-open times as short as possible to prevent sudden humidity drops. For a durian transport container, this factor has a direct impact on the in-spec arrival rate.

Cargo-loss control is not a matter of any single link. Temperature control, vibration protection, and humidity management — all three dimensions must be addressed together. When selecting a durian transport container, price alone cannot be the deciding factor; temperature-control precision, structural strength, and humidity management capability all need to be weighed. Build the prevention measures in upfront, and arrival quality takes care of itself. In durian transport, the details decide the loss rate.

CIMC Qingdao Refrigeration Industrial Base, established in 1999, is dedicated to the design and manufacture of ISO standard reefer containers as well as the production and customization of a wide range of refrigerated and insulated specialty products, serving customers across major logistics systems throughout North America, Europe, Asia, Australia, and beyond. The base's products cover application scenarios across the "sea, land, and air" supply chain systems, providing full-process equipment manufacturing solutions for cold chain equipment — from pre-cooling at production origins and manufacturing to midstream logistics transportation and last-mile warehousing.
