Proposta da migração digital do sistema de controlo da panela de cozimento do açúcar (de manual à automação) na Açucareira de Mafambisse

Abstract

This report suggest a migration and modernization project of the Sugar Cooking Pan control system, at the Mafambisse Sugar Mill, transitioning from a predominantly manual operation to a fully automated setup based on a Distributed Control System (DCS). The main objective was to optimize the crystallization process by improving precision, repeatability, and overall production efficiency. The project integrated key technologies, including Brix control using a Digitrans instrument, pan level monitoring through a dedicated level transmitter, and temperature regulation with Pt100 sensors. Centralizing these parameters within the DCS reduced the need for constant human intervention and enabled more stable and predictive control algorithms. The results demonstrated significant improvements in Brix and level stability, reductions in batch time, and enhancements in the final sugar quality. This work highlights the importance of industrial automation for boosting the competitiveness and sustainability of the sugar industry.
