With the rapid development of cold chain logistics, refrigerated trucks, as an important tool for ensuring the secure transportation of perishable goods such as food and medicine, are particularly important for their proper use and maintenance.

Chongqing refrigerated truck editor will explain some key precautions during the use of refrigerated trucks to ensure that the goods are in good condition during transportation.

1、 Maintenance of refrigerated compartment body

The compartment of a refrigerated truck is a crucial part in maintaining stable temperature of the goods. Regular inspections should be carried out on the inner and outer surfaces, edges and corners, as well as the interior floor, cooling vents, and other areas of the cabin to avoid scratching and causing damage to the cabin. Damage to the cabin not only reduces its pressure bearing capacity, but may also affect its insulation performance, leading to increased energy consumption and damage to the cargo.

In addition, the inner surface of the refrigerated compartment should avoid freezing. If there is a layer of ice on the inner surface, it should be promptly removed with a de icing shovel to prevent the thickening of the ice layer from affecting storage space and vehicle performance. At the same time, temperature control adjustment should be accurate to avoid adverse effects of temperature fluctuations on the goods.

2、 Precautions for loading and unloading goods

Loading and unloading are important links in the transportation process of refrigerated trucks. Before loading, the carriage should be pre cooled to remove the heat trapped inside and ensure that the carriage temperature reaches the storage temperature required for the goods. The pre cooling time is generally recommended to be at least 1.5 hours, depending on the type of goods and the size of the carriage.

When loading, avoid stacking the goods too high and ensure that the loading height is not higher than the plane height of the air outlet. At the same time, do not stack the goods in front of the evaporator outlet to avoid obstructing the circulation of cold air. The goods should be stacked on double-sided pallets, and plastic film should not be wrapped on the fresh-keeping pallets to avoid blocking the circulation of cold air.

During the loading and unloading process, the opening time of the car doors should be minimized as much as possible to reduce the entry of hot and humid air. At the same time, action should be taken quickly to avoid prolonged exposure to the external environment that could lead to cold chain breakage.

3、 Temperature control and monitoring

Temperature control is crucial during refrigerated truck transportation. Drivers should set appropriate temperature control parameters based on the temperature requirements of the goods and constantly monitor the temperature of the carriage. If the temperature is too high, it is necessary to "cool down" to reduce the temperature; If the temperature is too low, it needs to be raised. Nowadays, many temperature controllers for refrigerated truck compartments are designed in the cab, making it very convenient to check.

4、 Preventive maintenance and inspection

Preventive maintenance can reduce the maintenance and operating costs of refrigerated trucks. In addition to daily maintenance and upkeep, regular inspections should also be carried out on the vehicle chassis, cabin refrigeration units, backup power supplies, etc. to ensure their normal operation. At the same time, it is necessary to regularly clean the interior of the carriage to prevent contamination of goods or blockage of the evaporator of the refrigeration unit.

As an important component of cold chain logistics, the correct use and maintenance of refrigerated trucks are crucial for ensuring the secure transportation of goods. By strengthening measures such as cabin maintenance, refrigeration machine maintenance, loading and unloading precautions, temperature control and monitoring, as well as preventive maintenance and repair, it is possible to ensure that refrigerated trucks remain in good condition during transportation and contribute to the healthy development of cold chain logistics.
