A CONTINUOUS PROCESS FOR HYPERACTIVATION OF FLUIDS FOR STERILIZATION

摘要

The continuous process for hyperactivation of fluids for sterilization uses a sterilizing fluid which is mixed with a gas that is inert with respect to the fluid. A sterilizing mixture is obtained which is subsequently evaporated by means of introduction into an evaporation tube in a condition of annular motion, where a liquid phase of the mixture flows against the heated walls of the evaporator at a slower speed than the gaseous phase thereof, which flows in the central zone of the evaporator, internally of the liquid phase. A gaseous vapour/inert gas mixture is thus obtained, which is subjected to a waiting period during which the mixture flows through a transit device which transfers it to a sterilization chamber, a temperature of which is lower than a dewpoint temperature of the gaseous mixture, where a product is sterilized.
