Avaliação do sistema de medição de concentração de soda em uma indústria de bebidas não alcoólicas

Abstract

The present work was initiated aiming at the reduction of consumption of caustic soda in the process of cleaning the production lines of a non-alcoholic beverage industry in Minas Gerais, however, during the process there were great deviations in the analysis of the concentration of the studied solution, being necessary a measurement system analysis of the titrometry to guarantee reliable data and, from then on, make it possible to apply the DMAIC methodology for the effective reduction of soda consumption. With the application of the repeatability and reproducibility study it was possible to identify flaws in the method and tools used, which were improved and standardized, with a new analysis taking place after the modification of this system. As a result, we highlight the standardization of the process with an increase of approximately 63% in the precision of the measures and the practice of the teams involved in quality tools that culminated to development of critical sense and better delineated analyzes of possible failures in other activities in the sector. The titrometry analyzes performed with the use of the automatic burette, instead of the manual method, also reduced the quality analysts’ time devoted to this activity, making them more productive.
