Abstract
A sterilization method and an installation for producing sterile bottles by blow molding sterilized preforms includes, at the spraying station, the flow of sterilizing product atomized onto each preform whose temperature (T1) is less than the condensing temperature (Tc) of the sterilizing product so that a film of mist of the sterilizing product deposits by condensation at least onto the inner wall to be sterilized, and, at the activation station of the sterilizing product of the sterilizing unit, each preform treated in the aforementioned manner is heated by radiation to a temperature (T2) greater than or equal to the activation temperature (Ta) in order to sterilize at least the inner wall of the preform.
