With the improvement of people's living standards, the demand for fresh products is increasing day by day, the market scale of cold chain logistics is expanding rapidly, so recently many friends want to enter the cold chain logistics business, I think this is a good idea, but friends who want to engage in cold chain transport must first have a suitable refrigerated truck, because a high-quality refrigerated truck can make the fresh products in transport to maintain the right temperature, so that they are fresh, not spoiled, which is the basic condition for you to be able to engage in cold chain logistics transport. Therefore, how to buy a suitable refrigerated truck to create benefits for yourself?
As we all know, the general structure of the refrigerated truck is divided into three parts: chassis, insulation box, and refrigeration unit. Only these three parts are reliable quality to ensure that the refrigerated truck in the refrigerated transport process is stable and reliable. Selection of a good refrigerated truck, you need to consider the performance of the chassis, insulation box structure, insulation performance, refrigeration unit refrigeration effect.
Refrigerated truck chassis is equivalent to the body of the refrigerated truck, like the human legs, must be strong and reliable.
A The best to choose the chassis equipped with a well-known engine is the "heart" of the reefer, a good engine is the basic guarantee of the reefer safe driving, to ensure the normal operation of the refrigerated unit, can effectively protect the safety of goods, to avoid economic losses. Select reefer truck, it is recommended to choose a big brand, good reputation, strong power, and after-sales guarantee of the engine, such as Isuzu engine.
B It is best to choose a chassis with a high-powered generator, because refrigerated trucks in transport, refrigeration units need to run all the time, the demand for electricity for the vehicle is very large, so refrigerated trucks have high requirements for generator power, to ensure that the refrigeration unit of electricity, high-powered generators can effectively guarantee the normal operation of electricity-using equipment. It is understood that the current Qingling automobile for refrigerated vehicles specially developed with high-powered generator chassis, the choice of refrigerated vehicles are recommended to choose with high-powered generator refrigerated special chassis, so more reliable some.
The refrigeration unit is the key part of the refrigerated truck, more important. Because the cargo space is smaller, the technical requirements in controlling the temperature are also higher. The general principle of selection is based on the volume of the refrigerated box and the transport of goods on the temperature requirements to choose a different power refrigeration unit.
It is reported that the current refrigerated truck refrigeration unit has independent and non-independent two forms. The choice of an independent refrigerator or non-independent refrigerator first depends on the size of the chassis selected, independent refrigerator volume is larger, requires a certain installation space, suitable for installation in large refrigerated trucks. Non-independent refrigeration machine volume is small, installed in the truck outside, near the cab above, does not take up space. In addition, is the transport distance to choose the refrigerator, the general short-haul transport choice of the non-independent refrigerator, long-distance transport will have to choose the independent refrigerator.
Generally speaking, the import of independent refrigeration unit expensive refrigeration effect is good, suitable for the large-volume holding tank, the temperature requirements of very sensitive goods, refrigeration effect is fast, fully guarantee the storage temperature of the goods. For example: for long-distance transport, the carriage is more than 7 meters, it is recommended to use an independent refrigeration machine, because in the long-distance transport process even if the car engine stops working, the refrigerator can still be normal refrigeration, to meet the safety of the goods transported.
Refrigerated truck insulation box body selection should be around the "good insulation performance, reasonable structure, lightweight, not easy to damage" these principles to carry out. A refrigerated truck body is different from the ordinary van, it needs to have a good sealing performance and thermal insulation effect, to ensure that the refrigerated goods are in a stable temperature environment. Refrigerated compartment design is mainly airtight performance and thermal insulation performance, usually, the structure of the refrigerated truck adopts a three-layer structure, the inner and outer skin using composite materials, such as glass steel plate, color steel plate, aluminum alloy, and other materials. Inner plate material should be transported different goods and take different materials, more expensive inner material plate should be stainless steel plate. The middle sandwich is insulation material, mainly using polyurethane foam material.
A Vegetables and fruits refrigerated truck transport a large number of stacked compartment bottom goods, it is recommended that the optional aluminum alloy ventilation tank at the bottom of the insulation box, ventilation and heat dissipation; to facilitate the flow of cold air throughout the car, and to maintain a balanced temperature in the compartment, if you are engaged in this aspect of the cold chain transport business, it is recommended that this money is best not to save.
B If you want to engage in the fresh refrigerated truck transportation business, because the cold seafood contains a lot of seawater, insulation box can be equipped with optional food-grade stainless steel, to prevent seawater corrosion, disinfection solution corrosion; this money you better not save, otherwise it is very easy to damage your truck, and life will also be greatly reduced
C If you are engaged in pork, beef, mutton, and other meat cold chain transport business, meat hook refrigerated truck in the transport of fresh meat, need to customize the top of the insulation box meat hook rail or movable frame meat hook rail skeleton, to effectively avoid the accumulation of hot spots, to facilitate the flow of cold air throughout the truck, rapid heat dissipation; this best also can't save.
