Services
In modern food factories,it is usual to have all the service lines,with the ex-ception of drainage,located between the ceiling and the roof.Services are then fed vertically to the various pieces of equipment.This design has many ad-vantages.In particular; it makes the maintenance of hygiene in food handling areas more economical.In some facto-ries,this type of design is impractical.In such cases; the service lines must be de-signed and installed so that they do not interrupt the smooth finish on walls and ceilings They must also be designed so that they are accessible for cleaning.The problem with exposed service lines is that dust and food particles form depos-its on the top surfaces of the lines.It is usually expensive to maintain such lines in a clean condition.When services are being installed,it is critical that service entry and exit points are adequately sealed,to prevent access by rodents
As mentioned ear her; windows should not be used for ventilation in food factories.Ventilation must be suf-ficient to prevent condensation on walls,ceilings,and overhead structures.Air-flows within the factory must be de-signed so as to avoid product contami-nation where there are single air entries and air exit points,airflows must be in the opposite direction to product flows.Air-intake points must be at least 1 m above both internal and external surfaces They must be fitted,at least,with a fly screen and ideally with dust filters It is now generally accepted that high-risk processing areas should be kept under positive pressure and that the air supply should be filtered to the required class Where refrigerated air is required,for food-safety reasons,in production areas,low air velocities are required to reduce the chill factor,To achieve low air ve-locities,various refrigeration systems may be used.
In most areas of food factories,floor drainage is essential.All floor drains must he fitted with an effective water trap and a suitable grill The sewerage lines must be adequate in size for effec-tive drainage during washing When de-signing factory drainage,allowance must be made for equipment,which re-quires a drainage outlet.Manholes should not be present internally within the factory,and,if present,they must be doubly sealed As food factory sewers have to be cleaned on occasion,man-holes must be provided outside the fac-tory to enable this cleaning to take place

服务流水线
除去天花板和屋顶之间的排水系统,现在的食品厂大多都拥有全套的生产服务线.流水线将各种机器纵向组合安放.这种设计有很多优点,主要是它可以在维护手工操作区的卫生时更加经济.在其他工厂,这种设计就不一定适用.这种方式下,生产服务线的设计和安装必须穿过墙壁或天花板以便不影响工作的连续性.同时设计也要便于进入清扫.暴露环境下的生产线最大的问题是回程和沉积在生产线上的食物残渣.维护整个作业线的卫生的花费是非常昂贵的.生产线安装过程中,对入口和出口的要严格密封,以防一些昆虫等动物进入.
顺便提一下别的问题.食品厂里窗户不应该被用做通风设备.通风设备应该能有效的防止在墙上、天花板和上方结构物凝结水珠.工厂里气流设计也应避免对食品造成污染,设计时应有单独的进气孔和出气孔气流方向应该与产品流动方向相反.进气孔设计时至少高出内表面和外表面1米以上.至少应该安装一个防蝇屏,理想情况下还应有灰尘过滤器.现在人们普遍接受了在高危工作区社定一定的压力,而且对于那些需要低温保存的食品,提供的气体也应通过过滤以满足要求.考虑到食品的安全,在生产区域气温应该降到较冷的水平,为了实现降温要求,需使用各种制冷设备.
食品厂多数车间,都须配备地面派排水系统.所有的地面排水系统都安装偶高效的水管和合适的排水罩.设计排水系统时,污水线尺寸要求应足够宽,以保证在清洁过程中迅速排水.应该有专向的经费生产这些满足排水要求的设备.工厂内不应设置下水道出入口,如果设置,必须设置双重密封.食品厂的下水道需要定期清洗.人洞应该设在工厂外边以满足清洗的需要.
