PROBLEM TO BE SOLVED: To provide a beverage filling apparatus which can produce a beverage in which a desired sterile condition can be secured with high energy efficiency.SOLUTION: A beverage filling apparatus 1 of the present invention composes a system which comprises an upstream positive pressure chamber 11, an upstream negative pressure chamber 21 provided downstream from the upstream positive pressure chamber 11, an irradiation chamber 31 provided downstream from the upstream negative pressure chamber, a downstream negative pressure chamber 41 provided downstream from the irradiation chamber 31, a filling chamber 61 which is provided downstream from the downstream negative pressure chamber 41 and which fills a plastic container 100 conveyed into the chamber with product liquid, and a downstream positive pressure chamber 77 provided downstream from the filling chamber 61. In the beverage filling apparatus 1 of the present invention, the pressure P3 at the irradiation chamber 31 is lower than the atmospheric pressure and is lowest in the pressures inside the system, and the pressure P6 at the filling chamber 61 is higher than the atmospheric pressure and is highest in the pressures inside the system.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】高いエネルギ効率で所望される無菌状態が確保される飲料を生産できる飲料充填装置を提供すること。【解決手段】本発明の飲料充填装置1は、上流陽圧室11と、上流陽圧室11より下流側に設けられる上流陰圧室21と、上流陰圧室より下流側に設けられ照射室31と、照射室31より下流側に設けられる下流陰圧室41と、下流陰圧室41より下流側に設けられ、搬送されるプラスチック容器100に製品液を充填する充填室61と、充填室61より下流側に設けられる下流陽圧室77と、を備える系を構成する。本発明の飲料充填装置1は、照射室31における圧力P3が、大気圧未満であり、かつ、系の内部における圧力において最も低く、充填室61における圧力P6が、大気圧を超え、かつ、系の内部の圧力において最も高い。【選択図】図1
