Resumo
O desenvolvimento de produtos ou a adequação a novas normas são fundamentais nas indústrias, devido à variedade de novas tecnologias, melhorias contínuas e novos modelos de produtos. Na era da Indústria 4.0, as empresas devem ajustar seus sistemas de produção e logística para se adequar à eficiência de custos, agilidade e flexibilidade do sistema produtivo. O estudo teve como objetivo principal avaliar e otimizar o desempenho energético de uma fritadeira industrial, adaptando-a às normas ASTM International e aos critérios do selo Energy Star. A pesquisa utilizou um modelo base (Fryers Restaurant RFB 40) e propôs melhorias para criar um novo modelo, denominado Efficiency. As principais alterações incluíram o revestimento da cuba com lã de vidro para retenção de calor, a otimização do defletor de calor para maior eficiência térmica e ajustes no injetor de gás para reduzir o consumo. O projeto da fritadeira à gás foi ajustado para atender à norma ASTM F1361-21 e à critérios da Energy Star, resultando em maior eficiência energética. O modelo Efficiency destacou-se por inovações como a redução do diâmetro do injetor de gás, economizando 20% no consumo energético (73.418 kJ/h contra 91.133 kJ/h do RFB 40), e o revestimento da cuba com lã de vidro, que reduziu a troca térmica com o ambiente. Apesar de maior emissão de monóxido de carbono (0,0610 ppm), manteve-se dentro dos limites normativos. O Efficiency é uma solução sustentável e econômica, ideal para mercados ambientalmente conscientes.
The development of products or adaptation to new standards is essential in industries due to the variety of new technologies, continuous improvements, and new product models. In the Industry 4.0 era, companies must adjust their production and logistics systems to align with cost efficiency, agility, and flexibility in the production process. The main objective of this study was to evaluate and optimize the energy performance of an industrial fryer, adapting it to ASTM International standards and Energy Star certification criteria. The research used a base model (Fryers Restaurant RFB 40) and proposed improvements to create a new model, named Efficiency. Key modifications included insulating the fryer tank with fiberglass to retain heat, optimizing the heat deflector for greater thermal efficiency, and adjusting the gas injector to reduce consumption. The gas fryer design was adjusted to comply with ASTM F1361-21 and Energy Star certification, resulting in greater energy efficiency. The Efficiency model stood out with innovations such as reducing the gas injector diameter, saving 20% on energy consumption (73,418 KJ/h compared to 91,133 KJ/h for the RFB 40), and the fiberglass-insulated fryer tank, which significantly reduced thermal exchange with the environment. Despite higher carbon monoxide emissions (0.0610 ppm), it remained within normative limits. The Efficiency model is a sustainable and cost-effective solution, ideal for environmentally conscious markets.
