How to load and unload the cargo in a refrigerator truck
Many new friends who buy refrigerator truck loaded and unloaded the cargo after buying a refrigerator, thinking that the cargo was put into the van body and filled the cargo compartment. This operation may also include many old drivers of refrigerator truck. The goods may be delivered, but the quality of the goods has been discounted. In order to clearer the refrigerator how to load and unload the goods? To better use the refrigerator, please pay attention to the following points, please pay attention to the following points:
Before loading, the carriage must be pre-cooled or pre-heated about 1.5h. Because the refrigerator truck is parked in the open air, usually the temperature of the carriage is the temperature of the external environment. After the cargo is loaded into the compartment, refrigerator truck the environmental temperature in the carriage will affect the temperature of the transportation of the goods, refrigerator truck which will cause the quality of the transportation of the goods to change. Cold until the necessary temperature for goods.
When loading and unloading, the refrigeration unit must be turned off. Many people do not turn off the refrigeration units when loading and unloading goods. This is a very wrong operation. The principle is: when the carriage is prematurely cold, if it is not turned off and open the refrigerator truck door, because the fans of the frozen unit evaporator are working, the frozen unit’s evaporator is working. The front of the fan is positive pressure,refrigerator truck and the back is negative pressure. Therefore, the air conditioner is blown out of the upper part of the compartment, refrigerator truck and the lower part will quickly sucked the hot air outside,
which will cause the temperature in the carriage to rise rapidly. Stop state, the air flow stops, and the wind pressure inside and outside the carriage is consistent, so the speed of the external hot air transmission into the compartment is relatively slow.
When using a refrigerator truck, keep the floor of the compartment clean. Due to the effect of evaporator fan, the air will circulate inside the carriage, causing the debris or dirt on the ground to be inhaled by the evaporator fan. Long term effects will inhale a large amount of impurities into the evaporator’s tray, which will affect the refrigeration effect of the refrigeration unit.
Appropriate packaging is essential for protecting goods. If frozen goods, refrigerator truck you should use a non-ventilation box. Because the wind blows the surface of the frozen cargo, it will cause the water loss in the goods, refrigerator truck which will cause the quality of the goods to decrease. In my country, it is not allowed to be sold for bulk frozen foods. This is the reason for packaging sales. For fresh goods, it is necessary to use side wall ventilation box. Due to its own characteristics, refrigerator truck fresh items are still in a breathing state during the storage and transportation process. If they cannot ventilate well, the goods will deteriorate.
When loading, do not pile the goods too high. Be sure to ensure that the height of the loading is not higher than the plane height of the outlet. If the front of the air outlet is blocked or too close to the goods,refrigerator truck it will not only affect the stored temperature of the goods, but also affect the normal work of the freezer. If the outlet is blocked by the goods, air conditioning cannot be circulated normally in the carriage, which will increase the local temperature of the goods. On the other hand,refrigerator truck some of the frost design of the freezing unit uses air induction defrosting, blocking the outlet, which will greatly reduce the default effect.
