摘要: The present invention relates to a method for sterilizing stretching means (12) of a container moulding device (10) fitted to a plant for manufacturing thermoplastic containers obtained by stretch-blow-moulding from production preforms, the said method for sterilizing the stretching means (12) comprises at least the steps consisting in: —introducing a determined quantity of a sterilizing agent into a sterilization preform (30), —during a step referred to as a conversion step, converting said sterilization preform (30) into a hollow body (50) by stretching—blowing into the said moulding device (10), said introduction of the sterilizing agent being performed in the vapour state in a sterilization preform (30) at a temperature that allows a uniform film of mist to be deposited by condensation onto an internal surface (32) of said sterilization preform (30), and in that at least two sterilization preforms (30) are then converted successively into hollow bodies (50) in the one same moulding device (10).

摘要: Disclosed is a process and a device for sterilizing gas filtration unit, characterized in that the sterilization process includes at least: —an application step consisting in circulating, through the gas filtration unit, a gas mixture including hot air and a determined amount of hydrogen peroxide vapor, in which the determined amount of hydrogen peroxide vapor is obtained by sequentially injecting, with a given time interval (t) between two successive injections, a given dose of hydrogen peroxide in the liquid state into the hot air; and —a sterilization step consisting, during the time interval (t), in circulating hot air through the filtration unit in order to eliminate, by evaporation, all or some of the hydrogen peroxide deposited on the filtration unit during the application step.
