STEAM STERILIZATION OR STEAM DISINFECTION PROCEDURE AND DEVICE FOR THE PERFORMANCE OF THE PROCEDURE.

摘要

Steam sterilization or steam disinfection procedure for the treatment of products to be sterilized inside a chamber in which: - in a phase of preparation procedure intended for the elimination of gas, a gaseous medium that is previously in the chamber, by reducing the pressure inside the chamber by aspiration of the gaseous medium, before introducing steam into the chamber for the formation of a mixed medium composed of the remaining gaseous medium and the steam, until a certain level of overpressure is reached and then the mixed medium formed from the chamber is extracted, - in a subsequent sterilization phase for the extermination of possible germs, steam is introduced into the chamber and a defined state of steam is maintained in the chamber with respect to pressure and / or temperature for a predetermined period of time, and - in a drying phase for drying d the product that is sterilized is largely eliminated the pressure of the chamber, the chamber is opened once the pressure of the chamber is balanced at room pressure, and the treated sterilized product is removed from the chamber, characterized in that during the The drying phase introduces a non-condensable gaseous medium, particularly air, into the chamber still filled with steam before a pressure reduction at a drying pressure level below the ambient pressure during a certain drying maintenance time, to thereby move the vapor mostly out of the chamber.
