Aseptic packaging has a specific dimension in the sphere offood industry and mus tbe treatedaccordingto the followingrequirements。23
无菌安装车间得要求ASEPTIC INSTALLATION ROOMREQUIREMENTS
无菌灌装机应安装在单独得灌装车间内。
Theasepticfilling machines shouldbe installedin a separate fillingroom。
只有遵守该条件,空气传播得细菌数量才会下降。增加包装产品带菌可能性得因素应予以避免。如果发生下列情况,车间中得带菌可能性将会增加: Upon plying withthisconditionthe quantity of airbornebacteria decreases. The factors, whichincrease thepossibility of non-sterility of the packed product, shallbeavoided。The possibilityof non-sterility increases in the room:
- 安装有酸奶产品或奶粉工厂等得加工机。
- where processing machines forsourmilkproducts or milk powderplants are installed etc。
—安装有洗瓶机与洗箱机。
-wherewashing machines for bottles orcrates are installed.
- 有强气流
—with strongair-currents.
-有同其她厂区得往来交通
-with traffic to and fromotherplant areas、
—有高湿度,如,装有杀菌器得车间以及在预杀菌与/或生产期间有蒸汽或热水排出得车间。
- withhigh humidity, such as theroomwhere the sterilizer is installedand where youhavedischarges of steamor hot water during pre-sterilization and/orproductionperiods、
-正在进行建筑或维修工作,导致扬尘与扬土。
—Where constructionorrepair works are beingcarriedout,what causes dustand dirttoappear、
灌装车间得要求FILLING ROOMREQUIREMENTS
过压Overpressure:
整个灌装车间应借助过滤得进气口保持“过压状态”。
The filling room, as a whole,should be maintained inan“overpressure con dition”by means of filtered airintake.
地板Floors:
地板应铺设防滑、抗酸碱得瓷砖。所有地板/墙角应为圆形,以便清洁。排水沟也应有到出口得斜坡。
Floors should bemade ofnon—slip andacid/alkali resistant tiles、All floor/wal lcorners should be rounded foreasycleaning.Thedraingully should also have a fall to outlet.
地板从包装机得后方到前方应有一个1、5% (1:75)得自然得“斜坡"(废水聚集在包装机得前面)。 Floors should have a natural “fall”of 1.5%(1:75)preferably fromthe backto the frontof thepackagingmachine (wastewater exits arelocated towardsthe front of the packagingmachine)、
地板得排水应借助沟槽排入一个有盖子得“卫生排水沟”中。
Floordrainage is served by a gullyinto a covered “hygienic drain”。
墙壁Walls:
贴上一米高得瓷砖;瓷砖必须抗酸碱。
Tile toaheight of minimum 1 m; the tiles mustbeacid/alkali resistant。
上述瓷砖应就是打磨过得,以便清洁。
Above the tile-line obtain such a finish that canbe easilycleaned.
所有窗台均应就是倾斜得,以便清洁并防止其成为储藏架。
All window—sillsshould be sloped for easycleaning and preventing their use ass torage shelves。
门口Doorways:
包括包装机进气通道在内得门口通常应关闭、
Doorways including packaging material intake passages are tobenormally closed。
天花板Ceiling:
天花板与天花板得结构必须防水,并易于进行干湿清洁、
Ceilings and ceiling constructions have to be waterproofedand easily accessiblefo rthe wetanddry cleaning,
通风Ventilation:
进风口Air Intake
在灌装机得后部有过滤气体沿墙壁分布、进口高度在0。3米与0、5米之间。
At therearof the filling machine with the filtered air distributedalong the walls、I ntakeheightbetween0、3 and 0.5 meters、
排气装置Exhaust:
在灌装机得前面,进风口对面墙得上面。
High up onoppositewalltothe intake, infront of the fillingmachines。注Not
离子电推进e:
由于双氧水杀菌系统过多敞露在灌装车间得空气中,无菌灌装机需要在上部建筑上有计算容量为400立方米/小时得额外得排气设施。该排气量应包含在灌装车间得总体计算中。
Aseptic filling machines needanextra exhaust facility abovethe superstructure wit h a calculated capacityof 400 m3/hour as theH2O2sterilizationsystem ismore opento thefilling roomsatmosphere。This exhaustvolume should be included in the overall filling room calculation。
特别注意事项Special notes:
包装车间得温度应稳定在当地适合得水平上、该舒适得工作温度会随着地点得不同而有很大不同。通常该温度为18-300C。stc2052
Packaging room temperatureshould bestable at thelocal compatible level。Such a fortable working temperature varies considerablyfrom placeto place、Normally this compatible temperature is18-300 C、
湿度也就是一个兼容性问题;低于30%得RH为异常,高达70%时可视为舒适
仿呢料Humidity isalso a matter of compatibility;an RH of lessthan 30% is unusua land up to70%can be considered fortable。
TBA/19与TBA/21包装机散发得过氧化氢水气通常由综合排气系统连同包装机得废水一同处理、TBA/8机器为无菌室配有过压排气装置,应纳入车间得通风排气系统。
Hydrogen peroxide vapor emitted by the TBA/19 and TBA/21 packaging machines are normally handledbyan integrated exhaustsystem withthepackaging machines' waste water. TheTBA/8 machineis equippedwith anoverpressureexh aust for theaseptic chamber, whichshould be incorporatedinto theroom’s vent ilation exhaust system.
在TFA/3 与TBA/3上方,建议放置过氧化氢水气得排放装置与热负荷调节器。
Above theTFA/3 and TBA/3it isrecommended toplace an exhaust for hydrogen peroxide vapor and regulation of thermal load。

卫生条件Hygienic requirement
一般用空气降落试验检查灌装车间卫生状况,菌落计数不超过30个。
Have fallingout testto check thehygiene conditionof fillingroom and totalplatecount should be no more than30cfu per9cm plate、
空气降落试验方法:将灭菌营养琼脂倒入直径9cm并经过灭菌处理得培养皿中,放入灌装间,打开培养皿暴露15分钟;而后,放入35±2︒C恒温箱内保温两天,取出计数、
