PROBLEM TO BE SOLVED: To shorten a downtime in a beverage filling work while increasing the cleaning/sterilizing effect of an aseptic filling device.SOLUTION: An aseptic filling device is formed by sequentially providing each kind of stations including a content filling station along the flow of a preform or a container from the upstream to the downstream, and covering each station with a chamber. For the content filling station, at least one of CIP(Cleaning in Place) and SIP(Sterilizing in Place) is performed, and for the external surface of a filling nozzle in the content filling station heated by CIP and SIP, SOP (Sterilizing out of Place) is performed.SELECTED DRAWING: Figure 4【課題】無菌充填装置の洗浄・殺菌効果を高めつつ、飲料の充填作業におけるダウンタイムを短縮する。【解決手段】プリフォーム又は容器の流れに沿って、その上流側から下流側へと内容物充填ステーションを含む各種ステーションを順に設け、各種ステーションをチャンバーで覆うことにより無菌充填装置を構成し、内容物充填ステーションについてCIP及びSIPの少なくともいずれか一方を行い、当該CIP及びSIPによって加熱された前記内容物充填ステーション内の充填ノズルの外面についてSOPを行う。【選択図】図4
