Key points of cold chain transport

Temperature control

Maintain a constant temperature: During cold chain transportation, it is necessary to ensure that the goods are always within the specified constant temperature range. Different goods have different temperature requirements, such as meat products cooling storage temperature of 0℃ -1 ℃, frozen storage temperature of -21 ℃ -18 ℃, relative humidity of 85%-90% and 95%-98% respectively; The transportation temperature of most fruits and vegetables for 1-2 days is 0℃ -4 ℃, the storage and transportation temperature for 2-3 days is roughly 0℃ -2 ℃, and the relative humidity is 95%-100%.

Temperature monitoring: The use of GPS and other logistics tracking technology to monitor temperature changes during transportation in real time, timely adjustment of temperature fluctuations, to prevent damage or quality reduction of goods caused by temperature fluctuations.

Cargo safety

Avoid damage: Ensure that the goods will not be damaged due to extrusion, collapse and other accidents during transportation. Choose experienced drivers and safe means of transport, arrange cargo loading reasonably, avoid loading too high or unreasonable stacking.

Cargo inspection: Check whether the goods are damaged or thawed in advance, and carefully check the packaging and quality status of the goods with special requirements (such as perishable food, medicine, etc.).

Vehicle correlation

Vehicle selection: Select vehicles with closed structure, thermal insulation function, suitable for freezing and refrigeration for transportation, such as refrigerated trucks, refrigerated containers and other thermal insulation transport tools. For cold chain logistics transport, the particularity of the vehicle is more important, which is directly related to the temperature maintenance and safe transportation of the goods.

Vehicle maintenance: Regular maintenance and inspection of refrigerated vehicles to ensure the normal operation of the vehicle's refrigeration system, heat insulation equipment, etc., to prevent damage to the goods due to vehicle failure (such as damage to the refrigeration system). The truck should be inspected before loading and repaired as soon as possible if any problems are found.

Operation process

Loading and unloading link

Health requirements: The loading and unloading of goods should pay attention to health, as far as possible to shorten the loading and unloading time. If possible, the cargo platform is best designed to not produce a direct contact with the outside air structure, and should always keep the transport vehicle, cargo platform, etc., clean. For the transportation of meat products, it is also necessary to pay attention to health conditions during loading and unloading to prevent secondary pollution.

Fast operation: speed up the loading and unloading of goods, shorten the opening time, and the delivery personnel should move the products into the refrigerator as soon as possible to reduce the loss of air conditioning and the time that the goods are exposed to the unsuitable temperature environment.

During transportation: the transport vehicle should always maintain a low temperature, control the temperature in the carriage during transportation, operate in strict accordance with the temperature requirements of the goods, and adjust in time when the temperature is not the same.

Arrival handover: After arriving at the destination, the delivery of goods should be carefully counted, and the final service should be done. It is important to pay attention to safety when unloading.

Other points

Time management

Reduce transit time: minimize the transit time of the goods, rationally arrange the loading and unloading time, avoid the vehicle staying too long on the way, and ensure that the goods can reach the destination quickly and safely.

Turnaround time and links: For some products (such as meat products), the turnaround time and links of the product should be shortened as far as possible, so that the product is sold to the end consumer in a shorter time, so as to ensure the quality of the product.

Record and trace: Detailed record of the cargo information and transportation process of each transport, so as to trace and solve problems when they occur. This helps in the event of quality problems or disputes in the transport link, it is possible to quickly find the cause and clarify the responsibility.
