If you ask a long-distance driver to transport for many years, the truck can pull something, he should not know how to talk, because it is too broad to ask, trucks as the main road transport tools, can pull things too much: fruits, vegetables, wood , iron and steel... It seems to be all right. But nowadays, with the development of social economy, people's demands for transportation have been continuously improved, and private cars have become a major trend. If you change another question, you ask the old driver, “What can a refrigerated truck pull?†He should be able to tell you the answer—fruits, vegetables, seafood, and the “food†favorite, and a refrigerated truck can therefore be said to be a special food vehicle.
â— Want to eat food in ancient times? not that simple
The automobile was the means of transportation that humans invented at the end of the 19th century, and the “special car for food†did not appear in China until the 1980s. What should be done by ancient people in the deep northern interior of the mainland who want to eat delicious coastal or southern fruits? “I laughed and laughed, and nobody knew that it was litchi,†and the truth was revealed.
Litchi was born in southern China and is an exotic item in fruit. Unfortunately, it does not survive for a long time and it is difficult to keep fresh. The lychees that were tribute to the emperor in the past were nothing more than red salt, white sun, and honey, which meant that even the emperor Lao could not eat fresh lychees. However, by the time of the Tang dynasty, Yang Yuhuan came out with a favorite pet, which was beautiful and pleasant, which attracted Tang Xuanzong and loved fresh lychees. Therefore, the emperor did not hesitate to use fast horses to keep lychees sealed in bamboo knots from day to night.
In addition to the fruit of the southern country, the sea goods of the South are also the royal delicacies. In ancient times, seafood and seafood were referred to as “hai wuâ€, and the Palace Museum had a map of “Qinggong Sea Mistakesâ€. It was a picture book drawn by the folk artist Nie Lun during the Kangxi era. Nie Yu used the brush to record the impression of the ancient people on seafood products.
However, for most of the ancient people, if they were not living on the beach, they would never see it for a lifetime. Even the most common crabs can only be eaten by the royal family. During the transportation process, in order to ensure that it will not degenerate, the ancients had to tie the crabs with cotton thread every year, seal them with felt, and then send them to the capital with a fast horse.
From this it can be seen that the ancient seals of the fast horses together act as the role of the refrigerated truck. At the time, the food was limited to the royal family. Ordinary people couldn't afford to even eat anything. The inconvenience of long-distance transportation, so that the ancients maintained the habit of relying on mountains to eat sea from the sea, the mainland people want to eat a lychee, it must be like Su Dongpo, was relegated to the Lingnan, can enjoy.
â— Refrigerated cars turn out to save food and water
However, as the times are improving and people are no longer willing to live on the days when they rely on mountains to eat sea foods, the number of food items is increasing day by day. The horses are no longer able to satisfy everyone's needs. Therefore, the food truck-refrigerated car has solved its urgent needs.
Although Xiao Ming, who is in Xi'an, is not the son of Li Gang, he can also buy fresh lychees from Maoming, Guangdong, and crabs from Yangcheng Lake.
Why do we say that refrigerated trucks are special food vehicles? This still needs to start with its use. The refrigerated truck has a refrigeration system and an insulated cabin. It is commonly used to transport frozen foods, dairy products, fruits and vegetables, and can be further subdivided into refrigerated trucks, dairy trucks, and fresh cargo trucks. In short, the goods being transported are mainly food-based, and we have thus given it a friendly "nickname." Of course, there is still a small part of it that is used as a medical drug transporter. It is more professional and will not be discussed here too much.
In the frozen car of the meat factory, we can see the words “unified delivery vehicle†in the carriage. Workers in the meat factory are carrying a pig into the car for transportation.
This is a tractor, which has been towing a three-axis milk semi-trailer with a maximum total mass of 40 tons. It can ship 30 tons of fresh milk.
Whether it is a refrigerated truck or a fresh milk transporter, refrigerated trucks for cold chain transportation have light truck chassis modified small trucks, and large and medium trucks with large semi-trailer chassis modifications. The former are mainly used for short-distance transportation, while the latter can be used for medium and long distance transportation. transport. For instance, Maoming Litchi, who is from Xi'an's Xiao Ming, must first transport the lychees from Guangdong to Xi’an with a large fresh-goods transport vehicle. However, transport in Xi’an must rely on a refrigerated truck modified by a small light truck.
â— Postscript

In the following article, we will further introduce the structural features of refrigerated trucks, so stay tuned.
