Desenvolvimento e integração de ferramentas para controle de processos em indústria de beneficiamento de milho

Abstract

This work had as main objective the development of methods capable of describing processes since classification to bagging of seed corn based on the seed profile, using ISO 9001 document records, through information of reprocessing rates, division of screens, historical flows and others. In general industry, for example, the capabilities of the equipment that will clean, separate, classify, treat and bag small seeds are different from the capabilities of the equipment that will process the larger seeds. Therefore, the same quantities of bags cannot be produced in the same time interval for different sizes and shapes of seeds. This work was structured using the DMAIC method (define, measure, analyze, implement and control) and developed with the help of quality tools, such as the Ishikawa Diagram to study root causes. The analysis was based on the Theory of Constraints (TOC) and initially a study was carried out relating the factors, critical or not, that determine the processing capacities according to the efficiencies of each equipment in the process. From this work it was possible to feed the PPC (Production Planning and Control) team with information to maximize the capacities according to the established orders and priorities. It is shown by means of process variables and historical data the capacities and constraints of production, aiming to ensure that necessary interventions are made in time to avoid further losses.
