Abstract

An apparatus for sterilizing, filling and sealing containers has a sterilization chamber, a cooling chamber, and a filling and sealing chamber, through which the containers are conveyed by means of an endless conveyor device. For presterilizing the chambers before the apparatus is put into operation, these chambers are acted upon by a gaseous sterilizing agent flowing through them, which is fed through an inlet or an outlet for the containers. In order that regions less affected by the flowing sterilizing agent as it flows, because they are in the lee, will also be disinfected well, the flow direction of the sterilizing agent is changed multiple times. A blower with a reversible flow direction is used for this purpose.
