Temperature adjustment and maintenance tips for refrigerated trucks

1. Refrigerated Truck Temperature Control Tips and Methods

Refrigerated truck freight rates may be higher than those for standard freight, but there are also more important considerations during transportation. If the compartment temperature becomes unstable during transportation, either too cold or too hot, the goods will not remain fresh for long and are prone to damage. The driver will also be liable for compensation for the damage.

1. Temperature Range

Different cargoes have different requirements for compartment temperature, and the specific temperature range during transportation depends on the specific storage and transportation conditions. If you are unsure about the appropriate compartment temperature, it is best to clarify with the cargo owner to prevent further losses.

2. Cleaning Requirements

Before loading, the interior of the refrigerated truck must be cleaned, disinfected, and ventilated. Failure to do so could lead to contamination of meat products through direct or indirect contact with the truck's surface. Some foods are highly odor-absorbent, so ventilation is also necessary to minimize the presence of strong odors in the cargo compartment.

3. Pre-cooling

Pre-cooling the cargo and the cargo compartment is essential before loading. Refrigerated trucks are designed to maintain the temperature of the loaded cargo during transportation. Loading cargo at high temperatures, or even in a cold storage environment with high temperatures, can deteriorate the quality of the goods. Therefore, it is essential to pre-cool the cargo and the cargo compartment to the appropriate temperature.的温度.

4. Stacking Techniques

Allow cool air to circulate inside the cargo compartment. To maintain a consistent temperature within the cargo compartment, ensure that there is space between the cargo and avoid overfilling.

5. Operation

Ensure that goods are moved in and out quickly. When the doors of refrigerated trucks are open, airflow from outside can cause the cold air inside the truck to dissipate, raising the temperature. Minimize the time the doors are open.

6. Precautions:

Stop the refrigeration unit when transporting goods. 

2. Maintenance of the insulation body of the refrigerated truck

Generally speaking, the daily maintenance and care of the insulated compartment of a refrigerated truck mainly includes the inspection of the outer surface of the compartment, the inspection of the inner surface of the compartment, the inspection of the edges and corners inside and outside the compartment, the inspection of the floor inside the compartment, as well as the internal lighting, refrigeration outlets, etc.

1. For the outer surface of the refrigerated truck body, try to avoid scratching it. On the one hand, this will reduce the ability of the fiberglass to withstand pressure and make it more prone to aging and deformation. On the other hand, it will cause the polyurethane filling inside to leak, thus affecting the thermal insulation performance of the body.

2. Maintaining the interior of a refrigerated truck requires proper temperature control to prevent ice from forming on the interior. If humidity is high, package refrigerated products, especially seafood, as tightly sealed packaging will reduce moisture evaporation into the truck compartment and minimize the possibility of ice forming inside the truck.

If a layer of ice forms on the interior of a refrigerated truck, remove it promptly with a de-icing shovel after each transport to prevent the ice from forming. This will not only reduce storage space but also increase vehicle weight and fuel consumption.

Similarly, the interior should be carefully protected to prevent damage from sharp objects or packaging.

3. For the maintenance and care of internal electrical equipment, because the electrical equipment in the refrigerated truck is in an environment with relatively high humidity and low temperature, it is necessary to prevent various short circuits caused by exposed power lines, and to prevent unnecessary damage to the heating lighting equipment due to alternating hot and cold temperatures.
