Many people have no impression of the cold chain, but in fact, its actual effect is familiar to most people. In layman's terms, it requires a complete supply chain system with a certain temperature control.

Systematic speaking refers to a special supply chain system that requires some special products or semi-finished products to be stored, transported, distributed, and used in a specific temperature environment, reducing losses and avoiding pollution. And what we are going to talk about today is a link in the cold chain-cold chain transportation.

Cold chain transportation is not limited to the transportation method. It only needs to ensure that the temperature is unchanged throughout the process. However, controlling the temperature requires mobile refrigeration technology and refrigeration equipment and facilities, so it is still very troublesome, and what we are going to talk about is the cold chain transportation process The problems encountered and unsolved in different types of goods or in different categories.

1. Product objects and industry categories in the cold chain system

1. Fresh and live products

For example, fresh vegetables; fresh fruits; meat and aquatic products that need to be frozen; flower products; poultry, chicken, duck eggs, etc.

Let's take flowers as an example. The purchase and delivery of flowers have particularly high requirements for their quality and flowering period. Perhaps they will simply wither and lose money.

Of course, this is also related to the imperfect infrastructure of my country's cold chain transportation, which leads to the high cost of cold chain transportation, and cold chain transportation will not be used in the transportation of flowers. Compared with foreign countries, it can ensure that the flowers are transported in the cold chain along the entire transport route.

If cold chain transportation is not applicable, it will have a huge impact on the flowering period of flowers. For example, lilies can only be kept fresh for 5-6 days if general logistics are used. -9 days, the distance is very large.

If one day my country increases investment in the construction of cold chain infrastructure, which greatly reduces its costs, the fresh and live products business such as the flower industry may usher in a quality upgrade.

2. Processed food

Such as quick-frozen food; cooked food such as meat; ice cream and dairy products; fast food materials, etc. They need time to stick to the proper temperature and avoid metamorphosis. These processed foods will easily metamorphose when the temperature rises slightly, and will change when the temperature is too low, just like ice cream will melt if it is too hot, and chocolate will crack if it is too cold. open.

Taking fast food and other food processing materials as an example, the current catering supply chain is moving towards an increasingly complete and cooperative direction, but one of the pain points of cold chain delivery.

In my country alone, due to the extreme shortage of cold chain transportation infrastructure, if the catering supply chain is to be completely improved, the construction of the cold chain logistics system requires catering companies and supply chain companies to spend a lot of money and Time to build and perfect can not only ensure the quality of the ingredients but also ensure the rapid supply.

However, due to the high cost, the cost of meals in high-quality restaurant management services remains high. The quality of meals in low- and medium-priced restaurants has yet to be discussed. There are still many catering companies that are shoddy when serving meals.

Although it is not only due to a series of reasons such as imperfect supply chain and lack of supervision, but the businessmen's opportunistic psychology and the decline in the quality of food materials during delivery accounted for a large proportion.

3. Pharmaceutical products

There are many medicines and devices that require refrigeration, and they need time to stay at low temperature. Otherwise, they will not only change, they may also pollute the environment, and they will also lose valuable medical resources.

The country has made great efforts in the construction of the cold chain system in this area. Although there is still a shortage, there is no huge demand for cold chain from other professions.

Many drugs will change color and taste at room temperature, so they must be stored in a low temperature environment. Some drugs can be stored at low temperature without changing for a long time. This greatly extends the shelf life and saves a lot of resources. Similarly, there are blood, vaccines, and vaccines. Biological reagents all require medical cold storage for storage and preservation to ensure their activity.

These refrigerated medicine blood can't be seen to have much use in the past, just like the usual warehouse, but it is actually attributed to a strategic resource, a storage resource.
