The last kilometer problem of cold chain logistics needs to be solved

Abstract: the healthy and rapid development of cold chain logistics is inseparable from the encouragement and support of national policies and the overall planning and guidance of the government. The state should establish relevant standards as soon as possible, formulate standards for base refrigeration facilities and refrigerated and insulated vehicles, and achieve the whole process control for fresh food, frozen products and drugs

what an experience it is to enjoy fresh fruit sitting at home. This problem, which was a little whimsical a few years ago, has now become a very common trivial matter. With the rapid development of cold chain logistics, people can continue to stay at home willfully and taste fresh food from all over the world

the waste caused by discarding rotten food in China reaches 70billion yuan per year, accounting for as much as 20% of the total food production. Some foods are discarded during transportation because they cannot be kept fresh for a long time. Experts say this waste is mainly caused by the lack of a "cold chain transportation" system. In the transportation of fresh and perishable goods, except for a few deaths caused by care on the way or vehicle discomfort, most of them are caused by decay, which is due to the decay on this kind of curve. For animal food, it is mainly the role of microorganisms. For vegetable foods, the main reason for the rotten imported cascade compressor unit is respiration. Knowing the reasons for the deterioration of fresh perishable goods, we can conclude that low temperature can inhibit the growth of microorganisms, slow down respiration, and achieve the purpose of prolonging the Preservation Practice of fresh perishable goods

the cold chain transportation process must rely on the cold user to freeze or refrigerate and other special vehicles before measurement. In addition to the need to have a truck for the same purpose, 1. Regularly check whether the connecting line of the rear panel of the controller is in good contact with the vehicle body and machinery. In addition, freezing or refrigeration and thermal insulation equipment must be set on the vehicle. In the process of transportation, special attention should be paid to continuous refrigeration, because microbial activities and respiration are strengthened with the rise of temperature. If the conditions of continuous refrigeration cannot be guaranteed in all links of transportation, the goods may begin to rot and deteriorate in this link. During transportation, the transportation method should be determined according to the type of goods, transportation season, transportation distance and transportation place. In the process of transportation, try to organize "door-to-door" direct transportation, improve the transportation speed, and the temperature should meet the regulations. In order to maintain the refrigeration temperature of frozen goods, they can be stacked closely. For fruits, vegetables and other goods that need ventilation and heat dissipation, a certain gap must be reserved between the shipments to ensure the integrity of the goods

in the process of refrigerated transportation, temperature fluctuation is one of the main reasons for the decline in the quality of goods, so the means of transportation should have good performance. While maintaining the specified low temperature, it is also necessary to maintain a stable temperature, especially for long-distance transportation

now more and more refrigeration manufacturers choose intelligent robots to operate, and the advantages of intelligent robots are becoming more and more obvious. In the cold storage, palletizing and handling can be realized by robots. In addition to the work expected to become robot work, the whole process intelligent traceability of cold chain transportation is also a hot word in the refrigeration industry

the whole process connection enables you to know the temperature and humidity of the cold storage on the computer; The temperature monitoring system of refrigerated trucks can eliminate the phenomenon that the original refrigerated trucks "cut corners on production and materials" do not turn on the air conditioner in order to save fuel, so that the cold chain continues to chain. In restaurants and large hotels, food delivery robots bring their own "incubators", so there is no need to worry about the reduction of taste and nutrition of dishes due to temperature changes

now more and more refrigeration manufacturers choose intelligent robots to operate, and the advantages of intelligent robots are becoming more and more obvious. In fact, the reason why low-temperature refrigeratory robots can heat up at this time is very simple: China's labor costs are rising sharply at present. The robot can work continuously for a long time, especially as a cold storage operation "ice and fire double sky", using the robot is convenient and efficient, and will not hurt people; Robots may also spray cold air to cool goods, which is absolutely good news for the "last mile" at the end of the cold chain of most fresh e-commerce

the healthy and rapid development of cold chain logistics is inseparable from the encouragement and support of national policies and the overall planning and guidance of the government. The state should establish relevant standards as soon as possible, formulate standards for base refrigeration facilities and refrigerated and insulated vehicles, and control fresh, frozen products and drugs in the whole process. Cold chain logistics is a common socialization problem, which needs to be improved at the government level, enterprise circulation level and consumer level. The government and circulation enterprises should perform their respective duties. On the premise of doing a good job in relevant connection, should the government also consider supporting a number of large-scale frozen products and fresh food platform enterprises. With the support of the government, these frozen products and fresh food platforms will also have a stable supply of goods, thus supporting the healthy and rapid development of cold chain logistics

according to the analysis of insiders, at present, there are still many difficulties in the development of cold chain logistics in China. I believe that with the encouragement and support of national policies, these "shortcomings" will also be solved
