The present disclosure relates to the technical field of cold-chain transportation disinfection and sterilization, in particular to a disinfection and sterilization apparatus and method for a refrigerated container transportation system.
For prevention and control of major infectious diseases, public health means are more important than medical means. The novel coronavirus also has a certain period of survival time outside the human body, and can be adsorbed on the surface of an object to cause contact transmission. Many cases show that positive novel coronavirus nucleic acids are detected on some cold-chain food and/or cold-chain food packages and/or cold-chain food transportation tools. Cold chains can preserve food and also serve as routes for virus transmission, and once cold-chain food and/or cold-chain food packages and/or cold-chain food transportation tools are contaminated with novel coronavirus during production, processing and circulation, the low-temperature and high-humidity environment of traditional cold chains is conducive to long-term vigor of the virus, which can cause epidemic situations. How to scientifically and effectively cut off the transmission paths of novel coronavirus on cold-chain food, cold-chain food packages and cold-chain food transportation tools and strengthen the supervision of cold-chain food and all links in circulation is also important.
Existing disinfection and sterilization devices easily cause adverse effects on parts such as engines and tires of transportation vehicles in the refrigerated container transportation system if directly disinfecting and sterilizing the refrigerated container transportation system.
Therefore, there is a need for an effective disinfection and sterilization device and method for cold-chain logistics transportation, which cut off the transmission paths of novel coronavirus on cold-chain food and/or cold-chain food packages and/or cold-chain food transportation tools without destroying the parts such as engines and tires of transportation vehicles.
