Durian transport requirements vary significantly across origins and varieties. Thai Monthong, Vietnamese Ganyao, and Malaysian Musang King each differ in ripeness behavior, respiratory heat, and husk thickness. Even when using the same durian transport container, temperature-control parameters need to be adjusted depending on the variety being loaded. Climate conditions at different origins also affect pre-cooling time. Southeast Asian production zones are highly humid, with high fruit moisture content, and the dehumidification capacity of the container needs to keep pace. When selecting a durian transport container, a one-size-fits-all approach won't work — origin and variety both matter.

Thai Monthong durian has high production volumes and large export shipments. Its flesh is on the softer side, with high post-ripening respiratory heat, and quality declines noticeably within 24 hours of harvest. Transport temperature is controlled at 13 to 14 degrees Celsius, with fluctuations held within ±1 degree. In-container humidity is maintained at 85% to 90% — too low and the husk loses moisture and cracks; too high and mold readily takes hold. The pre-cooling phase must move quickly, bringing the fruit core temperature below 13°C within 6 hours. These parameters place demanding requirements on the cooling response speed of the durian transport container. The internal temperature must drop to setpoint within 30 minutes of refrigeration unit startup; any longer delay, and the flesh begins to deteriorate.

Vietnamese Ganyao durian has a thick husk and firm flesh, offering somewhat greater resistance to storage and transport. Its transport temperature can run slightly higher, at 14 to 15 degrees Celsius. Respiratory heat is lower than Monthong, so the refrigeration unit operates at lighter load with reduced energy consumption. However, Vietnamese production zones are even more humid, so the container's dehumidification system needs to be strengthened. Malaysian Musang King is different again — its flesh is fine and delicate, prone to softening after ripening, and more sensitive to temperature. Transport temperature must be pulled down to 12 to 13 degrees Celsius, with pre-cooling time compressed to within 4 hours. Tomanee durian (a smaller Musang King–type variety) has a thin shell that is easily damaged when stacked, so dividers are needed inside the container. All three varieties impose different requirements on a durian transport container in terms of temperature-control precision, refrigeration capacity, and humidity management.

Climate at the production origin also shapes the transport plan. Eastern Thailand's growing regions see annual mean temperatures above 30°C, so pre-cooling time must be compressed to within 4 hours. Southern Vietnam has a long rainy season, calling for stronger container sealing to keep rainwater out. Penang in Malaysia sits on the coast, where salt spray corrosion is severe, and the container's exterior panels require anti-corrosion treatment. Durian transport container configurations differ from origin to origin — refrigeration unit capacity, insulation thickness, and ventilation design all need to be tailored to actual conditions. Whether to use polyurethane foam or vacuum insulation panels (VIPs) for insulation depends on voyage length and external temperatures.

Origin and variety together determine the technical parameters of a durian transport container. Temperature range, humidity control, pre-cooling speed, and refrigeration capacity — each of these specifications has to be calibrated to local realities. When choosing a container, first clarify the variety being shipped and where it is being shipped from, then match the container configuration accordingly. Standard reefer containers suit Monthong; Musang King calls for enhanced refrigeration; Ganyao allows parameters to be eased somewhat. Get the details right, and the loss rate comes down.

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.
