ABSTRACT:
Apparatus for sterilizing containers, for example open-topped plastic pots for receiving foodstuffs, comprises an aerosol generator which atomizes a liquid sterilizing agent and subsequently entrains the droplets of sterilizing agent in a carrier gas stream for delivery to a corona discharge wherein a charge is imparted to the droplets. The apparatus also comprises means for establishing an electrostatic field about a container to be sterilized whereby the charged droplets will be directed to the surface of the container to form a uniform coating thereon. The efficiency of the apparatus is enhanced by switching the polarity of the electrostatic field, for example as a function of corona current and also by minimizing the possibility of liquid sterilizing agent collecting on surfaces of the apparatus and subsequently falling on a surface of a container being treated.
