TECHNICAL FIELD
[0001] The present application relates to the technical field of cold chain transportation, in particular to a sterilization and odor removal mechanism for a cold chain container. BACKGROUND
[0002] At present, the cold chain logistics industry is booming, and the internal environment of the cold chain container, as the core transportation carrier for protecting the quality of various perishable goods, has undoubtedly become the focus of the industry. The range of goods carried by the cold chain container is extremely wide, covering fresh food, pharmaceutical products, flowers and plants, and many other categories. These goods have extremely strict requirements for storage environment, not only requiring specific low-temperature conditions, but also having extremely high demands on air quality.
[0003] During the long transportation journey, the environment inside the cold chain container is a breeding ground for bacteria and odor. On the one hand, the microorganisms carried by the goods can still grow continuously, although their reproduction rate is slowed down in the suitable low-temperature environment. Some psychrophilic bacteria can even multiply rapidly in low-temperature conditions, posing a serious threat to the quality of goods. For example, during the transportation of fresh meat, psychrophilic bacteria such as Pseudomonas can gradually decompose the protein and fat in the meat, causing the meat to spoil and emit a foul odor. On the other hand, the problem of mutual odor between different goods is also common, such as the mixing of the fragrance of flowers and the smell of food, and the contamination of other goods by the special smell of medicine, which greatly affects the commercial value and shelf life of the goods.
[0004] The traditional ventilation system of the cold chain container only has the basic function of air circulation, and it can only simply replace the air in the container. However, it is difficult to achieve effective purification and treatment of the large number of bacteria and complex odors in the air. Some cold chain containers use single sterilization or odor removal devices. However, these devices have exposed many serious problems during actual operation. The equipment hinders the normal circulation of air in the container when it is working, greatly reducing the overall air flow, and thus affecting the air circulation effect inside the entire container. In addition, the existing technical means generally have the disadvantage of single function, and cannot simultaneously achieve efficient sterilization and odor removal in the same device, which is far from the actual needs of the cold chain container for complex air treatment.
