Only a bottle properly preliminarily heated is sterilized by hydrogen peroxide. Temperature inspection to the bottle is performed while travelling the bottle. During the inspection, a bottle of which temperature does not reach a predetermined temperature is removed and a bottle of which temperature reaches the predetermined temperature is continuously travelled, hydrogen peroxide condensed mist &#x3b1; is blown toward a mouth portionof the bottle by a spray tubedisposed at a predetermined position, and hot air is blown into the bottle from the nozzle while the nozzlefollowing the mouth portion of the bottle. According to such operation, only the bottle properly heated can be sterilized by the hydrogen peroxide, Thereafter, beverage fills the bottle, which is then sealed.

Beverage filling method and apparatus

A cap sterilizer () includes an infeed chamber (), a sterilant atomizing chamber (), and an air rinse chamber (). At least the infeed chamber () and the air rinse chamber () are exhausted. Both an exhaust pressure (E) in the infeed chamber () and an exhaust pressure (E) in the air rinse chamber are higher than an exhaust pressure (E) in the sterilant atomizing chamber (), or the sterilant atomizing chamber () is not exhausted.

Cap sterilizer, content filling system, cap sterilization method, and content filling method

An aseptic filling machine and an aseptic filling method are provided with which a petaloid-shape bottle or an unstable bottle is filled with sterilized content and sealed with a sterilized cap in an aseptic atmosphere is discharged without a delay from an aseptic zone to a non-aseptic zone and even if the petaloid-shape bottle or the unstable bottle falls over on a discharging conveyor when being discharged from the aseptic zone to the non-aseptic zone, a stopping time of the aseptic filling machine is shortened by providing a barrier chamber into which air containing a gas of a sterilizer is supplied and a discharge portion chamber that shields discharge portions that are provided downstream of the sealing portion that fills the content into the bottle and seals the bottle with the cap.

Aseptic filling machine and aseptic filling method

A cap sterilizer () includes an infeed chamber (), a sterilant atomizing chamber (), and an air rinse chamber (). At least the infeed chamber () and the air rinse chamber () are exhausted. Both an exhaust pressure (E2) in the infeed chamber () and an exhaust pressure (E4) in the air rinse chamber are higher than an exhaust pressure (E3) in the sterilant atomizing chamber (), or the sterilant atomizing chamber () is not exhausted.

Beverage filling apparatus

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.
