Abstract:
In a continuous process for hyper-activation of fluids for sterilization, comprising the phases of:mixing the sterilizing solution with a gas which is inert with respect to the sterilizing solution, so as to obtain a two-phase inert gas/sterilizing solution sterilizing mixture; evaporating the sterilizing solution contained in a mixture to form a gaseous vapour/inert gas mixture; blowing the gaseous mixture onto the material to be sterilized where the vapour condenses; the improvement wherein the evaporation phase is carried out by introducing the two-phase sterilizing mixture into a tubular evaporator with a flow of annular motion in which the liquid phase of the mixture passes over heat exchange walls of the evaporator at a reduced velocity compared with the velocity of the gaseous phase of the mixture which passes through the central zone of the evaporator.
