Estudo de caso de eficiência energética em indústria alimentícia

Abstract

Energy efficiency has been established as one of the central pillars for the sustainable development of industry, especially in the food sector, whose energy demand is significant due to intensive processes in cold, ventilation, compression and cargo handling. In this context, practices that aim at the rational use of electric energy gain prominence, both for their environmental benefits and for the favorable economic impacts they provide. The adoption of measures aimed at efficiency not only reduces energy waste, but also collaborates directly with corporate goals related to sustainability, competitiveness and innovation. The present work is part of this scenario, proposing an applied analysis of the operation of electric motors in ventilation systems of a refrigeration plant, with emphasis on freezing tunnels. The proposal aims to identify opportunities for improvement through technical and operational adjustments in existing components, without the need for immediate large investments in new equipment. The strategy involves the study of the behavior of the motors in front of the demands of the system, evaluating its conformity with the dimensioning, efficiency of operation and influence on the thermal process of the plant. To support the proposal, a theoretical investigation was carried out on the main concepts related to energy efficiency, including electrical losses in engines, yield curves, optimal operating load and impact of mechanical changes in equipment performance.

To support the proposal, a theoretical investigation was carried out on the main concepts related to energy efficiency, including electrical losses in engines, yield curves, optimal operating load and impact of mechanical changes in equipment performance. The methodology adopted considered field measurements, operational data analysis, technical simulations and energy consumption projections, using appropriate tools to estimate the potential impacts of proposed modifications. Finally, the initiative contributes to the strengthening of corporate strategies aimed at optimizing resources, reducing operating costs and mitigating environmental impacts. The analysis presented in this work seeks to offer technical subsidies for more conscious and assertive decisions in the use of electric energy, promoting a modern approach and aligned with current challenges of the industry. By emphasizing the relationship between applied engineering, sustainability and competitiveness, the study reaffirms the relevance of energy efficiency as an indispensable tool for improving production processes, demonstrating that well-planned interventions can generate significant impacts at various levels of the organization.
