The present invention provides a filling valve which affords an excellent sterilization capability and a high maintenance capability. The valve includes a tubular nozzle, an operating rodwhich is fitted in the nozzleso as to be elevatable, and an opening/closing valveformed by a valve seaton the internal surface of the nozzleat its bottom end and a valve elementformed at the bottom end of the operating rod. A portionof a reducing diameter which gradually reduces the cross-sectional area of the filled liquid passagein a downward direction and a portionof an increasing diameter which gradually increases the cross-sectional area of the filled liquid passagein the downward direction are formed on the internal surface of the nozzleat an upper portion thereof. A plurality of straightening vanesare formed on the internal surface of the nozzleat a location below the portionof an increasing diameter.

A vessel conveying system includes a dryer disposed within a first sterile chamber. If a vessel stays within the dryer for a prolonged length of time, it will be deformed under heat. Accordingly, the vessel is removed by a reject wheel and dropped onto a discharge chute disposed below. A downstream portion of the discharge chute is surrounded by a second sterile chamber, which is separate from the first mentioned sterile chamber, A glove mounted on the wall of the second chamber enables access to the discharge chute while maintaining the chute in a sterile condition. A door is mounted on the wall of the second chamber, and the rejected vessel is discharged through the door. The sterile chambers are disposed within a processing chamber. The pressure within the first chamber is controlled to be higher than the pressure (atmospheric pressure) within the processing chamber and the pressure within the second chamber is controlled to be lower than the atmospheric pressure. As a consequence, a vessel rejected by the reject wheel can be removed without destroying an internal ambience of the sterile chamber surrounds the reject wheel.
