摘要:
The present invention relates to a process and a device for sterilizing gas filtration means, characterized in that said sterilization process comprises at least: - an application step consisting in circulating, through the gas filtration means, a gas mixture comprising hot air and a determined amount of hydrogen peroxide vapor, in which said 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 said time interval (t), in circulating hot air through said filtration means in order to eliminate, by evaporation, all or some of the hydrogen peroxide deposited on said filtration means during said application step.
摘要:
The invention concerns a method whereby in an installation making containers by blowing or drawing and blowing pre-heated preforms, sterilised containers (110) are obtained by wetting (45) the preforms (3) using an appropriate heat-activated sterilising product, and in activating the product by heating means (100) which also provide a suitable heating profile to the preforms to prepare them for blowing.
