ABSTRACT:
The presterilization of packaging machines for the manufacture of aseptic packing containers can be carried out with the help of sterile air and liquid sterilizing agent, which are blended so that a gas saturated with sterilizing agent of a suitable temperature and dew point is obtained. In order to achieve a rapid and effective volatilization of the liquid a circulating movement is imparted to the hot sterile air as the sterile liquid is introduced into the center of the circulating movement. An apparatus using this method comprises a chamber with a helical guide rail and a spray nozzle for the sterilizing liquid.
