Abstract: In this paper,the structure of the aseptic packaging aseptic isolator is analyzed,and the conditions to ensure that there are no microbes in the aseptic isolator are studied.In order to ensure microbe obstructability of the three dimensional turbulent flow field in an aseptic isolator,a new analysis method is put forward. Through appropriate theoretical calculations,the authors establish the function of the aseptic gas flow velocity,the beginning velocity of the dust or the waterdrop and the thickness of the aseptic gas curtain.At the same time,a vast amount of experimental data are obtained from several corresponding model tests to find the least amount of the aseptic gas and satisfying thickness of the aseptic gas curtain.

Key words: aseptic isolator, aseptic gas, curtain
