ABSTRACT:
A sterilization device on a filling and sealing machine for cup-shaped packaging containers has an endless conveying device in a sterilization chamber. The conveying device is equipped with carrier plates for the packaging containers has two deflection segments one above the other, and two vertical straight segments between them. A preheating device and a sterilization device for applying the sterilization medium are associated with the ascending straight segment, and a drying device is associated with the descending straight segment. The treatment medium, such as warm air, sterilization means and sterile drying air, are blown through nozzles descending into the conveyed containers. During passage through the upper deflection segment, the applied sterilization medium acts for a specific period of time: while the containers point downward with their openings. The containers occupy a horizontal position in the straight segments.
