The present invention relates to a novel coronavirus sterilization and disinfection device, in particular to a novel coronavirus sterilization and disinfection device for cold chain transportation of food and a sterilization method thereof.

Background technique

Coronavirus is a widespread virus, especially the novel coronavirus (new coronavirus for short) that began to spread widely in November 2019. Due to its high infectivity and high concealment, it has spread widely since its discovery. . It has caused extremely serious harm to people's life and health.

The new coronavirus can be excreted through respiratory secretions, and can be transmitted through oral fluid, air injection, contact, etc. Moreover, the new coronavirus can survive for a long time at low temperature, and the longest survival period has been reported as long as 105 days.

Due to its long-term survival at low temperature, cold chain transportation of food has become the main virus transmission route. At present, the disinfection method of food transported in the cold chain usually uses various disinfectants for surface spray disinfection. This disinfection method is not only inefficient, but also has poor disinfection effect, which is easy to cause omissions. In particular, disinfectant disinfection can only sterilize the outer packaging of food, but cannot sterilize the food itself, and there is still a risk of infection.
