How to ensure the safe and quick delivery of goods to the destination during transportation
       With the rapid development of China's economy and the continuous improvement of the level of the people living in the refrigerated transport industry, more and more perishable types of food, so the use of increasingly wide range of refrigerated trucks, refrigerated food from frozen, raw Fresh agricultural products, biological research drugs, chemical products, electronic products, fresh flowers, high-grade furniture, etc. have all been associated with refrigerated trucks. Its purpose is to ensure the quality of the product is stable. However, the phenomenon of product damage during use still exists. Correcting the causes is mainly due to incorrect use of refrigerated trucks. So how do we use a refrigerated truck? How can we avoid the risks due to improper use? Qingdao Yakai Automobile Industry & Trade Co., Ltd. summarizes the following points based on its accumulated experience over the years:
1. Correct operation ensures that the goods can be stored and transported in good condition.
Only the correct use and operation of a refrigerated truck can guarantee the complete delivery and preservation of the goods. Because refrigerated trucks are used exclusively for temperature-sensitive products, the guarantee of temperature is the key to the operation of refrigerated trucks. Improper use or improper operation can result in the goods not being stored or shipped in good condition.
2. Preventive maintenance can minimize maintenance and operating costs.
In our normal use, maintenance and maintenance of vehicles and chillers are inseparable. Only when the equipment is properly maintained and maintained on time, the normal use of the equipment can be guaranteed and the service life of the equipment can be extended.
3, suitable packaging is essential to protect the goods.
For non-ventilated containers for refrigerated goods, side-ventilated containers for fresh produce. The box must be compressive. Because the frozen goods do not allow the wind to blow from the surface, because the wind blows over the surface of the frozen goods, the moisture in the goods will be lost and the quality of the goods will decline.
4. Set the thermostat to the desired temperature and prechill the car for 1.5 hours to drain the heat left in the car; when loading, the refrigeration unit will be turned off and the cargo will be loaded quickly. The goods must be pre-cooled to the required temperature, and the temperature of the goods checked at the time of loading; the refrigeration unit is used to maintain the temperature of the goods, not to reduce the temperature of the goods.
5. Even if the capacity of the unit exceeds the actual requirement, insufficient air circulation will be the main reason for the deterioration of the goods; any obstruction around the goods may cause “hot spotsâ€.
A qualified refrigerated truck must ensure that there are good ventilation on the six sides of the carriage and there is no obstruction on the six sides of the cargo; good air circulation can ensure that the goods are transported under the proper temperature requirements. The cold (hot) gas blown by the refrigeration unit isolates the cold (hot) source that enters the compartment from the outside and protects the cargo.
6, the goods must be stacked on a double-sided pallets; fresh cargo pallets can not contain film, the film will block the circulation of cold air flow to the goods; can not block the floor under the goods.
The general refrigerated truck floor uses vented aluminum rails; however, some refrigerated trucks do not have aluminum rails, and flat anti-skid floors are used. The non-slip floor is usually used as a third-party transportation company or a company transporter for dairy products. The purpose is to be suitable for the transportation of multiple products or to facilitate the cleaning of the ground. However, it must be noted that the loading must be done with double-sided pallets to ensure the circulation of cold air on the ground. It is forbidden to stack goods directly on a flat floor.
7. Do not stack cargoes in front of the evaporator outlets, as this will impede the cold airflow; obstruction above the cargo will cause a short circuit in the cold airflow. Maintain a minimum distance of 225 mm between the top of the cargo and the roof.
When loading, do not stack the cargo too high. Make sure that the loading height is not higher than the level of the outlet. If the front of the air outlet is blocked by the goods or is too close to the goods, it will not only affect the storage and transportation temperature of the goods, but also affect the normal operation of the refrigeration unit. Because the air outlet is blocked by the cargo, the cold air (or hot air) cannot be circulated in the compartment normally, thus causing the local temperature of the cargo to rise.
8. The interior of the carriage must be kept clean; there should be no wrapping paper or paper debris on the ground; debris will impede the flow of air or be inhaled by the evaporator. Properly carried; when the door is opened, the freezer should be closed; the opening time of the door should be shortened as much as possible; use bar-shaped curtain as much as possible when loading and unloading the goods. Use partitions to separate dry goods (empty baskets) and perishable items.
Qingdao Yakai Automobile Industry and Trade Co., Ltd. reminded the majority of refrigerated truck customers, the professional operation of operators and the use of refrigerated trucks, is the key to ensure the quality of temperature-controlled goods. It also ensures that the refrigeration equipment can work properly.
