Aplicação do lean six sigma na indústria de esmagamento de soja: estudo de caso na variabilidade do processo de moinhos quebradores

Abstract

Brazil is the largest soybeans producer in the world, with of over 135 million tons in 2020/21, 175.4 million tons projection for the 2030/31 harvest. In the soy crushing industry, where the raw material is transformed into higher-added value products, physical and chemical stages take place until the oil can be extracted from the grain. In the breaking stage an ideal and standardized value is estimated, the deviations presented in this operation block reflect in the efficiency of the whole process. The 6 Sigma methodology, a quality tool, aims to reduce the variability of the process, reducing losses and bringing profitability to companies. The objective of the present work was to implement 6 Sigma, in the process of breaking mills in order to reduce process variability. To accomplish this, the project was built based on the Define Measure Analyze Implement Control (DMAIC) methodology, one of the pillars 6 Sigma. As a result of the study, it was possible to identify flaws in the process, propose improvements, as well as recognize the original of the problem. Thus, the soy industry presents many gaps for the implementation for the tool’s, and consequently opportunities for great results.
