Abstract

The variables involved in a cleaning and sanitization procedure are fundamentally time, temperature, chemical and mechanical actions. The search for the optimization of the correlation between them determines the effectiveness of the operation, and any change in value of one of them will result in a system rearrangement. Whereas some concepts such as cost reduction, process optimization and the search for continuous improvement, research rose the following question: Was it possible to optimize the process of cleaning Clean-in-place (CIP) of milk storage tanks and derivatives, reducing process parameters, maintaining efficiency and controlling chemical residual? With this line of thought, the research aimed to optimize the CIP process of milk storage tanks and derived from a dairy industry. The methodology was to optimize process parameters such as reducing the concentration of chemicals used, reducing the rinsing time, and display test deployment chemical waste. It was possible to first reduce the concentrations of chemicals used solutions (alkaline and acid) in 0,5%, representing an annual savings forecast with chemical approximately R$ 38 thousand. It was also possible to reduce some rinses times within the process that drawing a direct line to the flow of the rinse pump and the arithmetic mean of cleanups, we estimated annual savings of 84 million, 840 thousand liters of water. With the implementation of residual chemical indicator test, the process has become safer, because any alkaline residue or acid that the rinsing step can not be removed will be indicated in the residual test.
