The objective of this work was to propose a new strategy, based on objective and rational arguments and calculations, that can be implemented by plant designers and operators in the dairy industry to reduce operating time and the volume and load of effluents. The strategy is based on the on-line and off-line use of sensors and tracers, the accuracy, relevance, and robustness of which were evaluated for each phase of the sequence used for cleaning an industrial sterilizer. The efficient duration of each phase of the cleaning sequence (management of the end of operation) and the sorting of the fluids (management of mixtures and destination of fluids) were determined in real time. As a result, significant reduction in total overall duration of the cleaning sequence, wastewater volume (waste volume was reduced by half), and detergent volume (caustic soda and acid was reduced by up to a few tens of kilograms per cleaning) was achievable.
本工作旨在提出一种新策略，基于客观合理的论证和计算，可由乳品厂的设备设计师和操作人员实施，以减少运行时间和减少废水的体积和负荷。该策略基于传感器和示踪剂的在线和离线使用，对其在用于清洗工业灭菌器的序列的每个阶段的准确性、相关性和稳健性进行了评估。清洗序列的每个阶段的有效持续时间（操作结束管理）和流体的分类（混合物的管理和流体的去向）实时确定。结果，显著减少了清洗序列的总持续时间、废水体积（废水量减少了一半）和清洁剂体积（每次清洗减少了数十公斤的苛性苏打和酸）。
