This paper reviews the routine and periodic systems used to clean food equipment. The manner in which soil accumulates on surfaces, and factors affecting that accumulation are discussed. The mechanisms by which microbial development on the equipment surface is controlled by the system is also discussed. The contamination sequence of deposition, attachment, depletion, growth and contamination by the organism is presented in detail. Changes in surface microbial numbers over time are reviewed for system components and complete systems. The relationship between the amount of soil on the surface and microbial survival is examined. The ability of the routine and periodic systems to control soil accumulation and microbial development is discussed. Factors affecting design of a cleaning system are also presented. These factors are used to design a cleaning system, using a pipeline milking machine as an example.
本文综述了用于清洁食品设备的常规和定期系统。讨论了污垢在表面堆积的方式以及影响这种堆积的因素。还讨论了该系统控制设备表面微生物生长的机制。详细介绍了生物体的沉积、附着、消耗、生长和污染的污染顺序。回顾了系统组件和完整系统随时间变化的表面微生物数量。研究了表面污垢量与微生物存活之间的关系。讨论了常规和定期系统控制污垢堆积和微生物生长的能力。还介绍了影响清洁系统设计的因素。以管道式挤奶机为例，利用这些因素设计了一个清洁系统。
