Background

The production of influenza virus from eggs is a mature means in the field of influenza virus immunization research and is widely reported in the prior art literature. For example, chinese patent application No. 2008801089689 discloses a method of infecting eggs of immunized hens with influenza virus and obtaining influenza virus suitable for use as an influenza vaccine. For another example, chinese patent application No. 2004800110059 discloses a method for preparing an influenza virus composition using eggs.

When influenza virus passage is carried out by utilizing eggs, the eggs are placed on a specific egg trolley and are incubated in a negative pressure area; after passage, influenza virus is obtained from the broken eggshells, the rest egg components are processed in a centralized way, and the egg vehicle for placing the eggs leaves the negative pressure area after being cleaned, disinfected and inactivated.

However, pollutants such as egg embryo liquid and egg embryo groups with influenza viruses are often attached to the egg trolley, so that the complexity of the cleaning and disinfecting processes is increased, the cleaning time of the egg trolley is further prolonged, and the production efficiency is reduced.

Disclosure of Invention

in order to complete the cleaning and disinfection of the egg trolley, a cold liquid filling system, a hot liquid filling system, a circulating cleaning system and a hot air drying system which realize the cleaning and/or disinfection function are arranged in the working chamber.

The cold liquid filling system and the hot liquid filling system are both used for filling cleaning water liquid into the working chamber, and the difference is that the hot liquid filling system can heat the cleaning water liquid at the water inlet to a preset temperature and then inject the cleaning water liquid into the working chamber. The cleaning water liquid filled by the cold liquid filling system is used for cleaning pollutants with influenza viruses, such as egg embryo liquid and egg embryo groups, attached to the egg trolley; the cleaning water liquid with the preset temperature, which is filled by the hot liquid filling system, can finish primary inactivation on the residual influenza viruses on the egg vehicle and in the working chamber environment.
