process for the sanitizzazione of containers and packaging materials, particularly for pharmaceutical and cosmetic, and installation for performing the process

摘要

A method for sanitizing packaging containers and materials, particularly for pharmaceutical and cosmetics use, characterised by: - feeding an oxygen stream into an ozonising chamber, - feeding a controlled quantity of the ozone produced in said ozonising chamber into a sanitizing chamber in which the containers to be treated have been previously placed, - after the ozone has remained in the sanitizing chamber for a predetermined time, purging said chamber with sterile air until a residual ozone concentration is obtained which is less than a predetermined safety value, - passing the stream of air and ozone leaving the sanitizing chamber through an ozone decomposition device.
