Abstract

This study presents the development of a rotary sample mixer designed to enhance the efficiency of research and development processes in sectors such as chemical, food, and pharmaceutical industries. The main objective was to propose a solution capable of performing multiple simultaneous mixes, eliminating the need for cleaning between tests and significantly reducing the total testing time. The methodology involved the detailed mechanical design of equipment with four independent compartments, using removable PET cartridges and a structure made of AISI 304 stainless steel and ASTM A36 structural steel. The mixer was modeled using CAD software and validated through dynamic simulations. Tests using granular polyethylene materials demonstrated good homogeneity, confirming the feasibility of the proposed design. The results indicate that the developed mixer can substantially improve productivity in testing environments, offering a cost-effective and functional alternative to conventional systems.

Holds a degree in Mechanical Engineering from Universidade Paulista (2018)

Leandro Cardoso da Silva, SENAI University Center São Paulo

I hold a degree in Mechanical Production Engineering from Centro Universitário Nove de Julho, a master’s degree in Materials Engineering from Universidade Presbiteriana Mackenzie, and a PhD in Mechanical Engineering from Universidade de São Paulo. I am currently pursuing a postdoctoral fellowship in Computational Fluid Dynamics (CFD) at The Catholic University of America.

My career includes extensive experience in both industry and academia. In industry, I worked for 14 years in multinational companies in the automotive sector, focusing on product and process development, specifically on critical components such as engine suspension, gearshift mechanisms, pedal assemblies, and exhaust and air intake systems for trucks, buses, and cars.

In academia, since 2011, I have served as a Professor and Researcher in undergraduate programs in Engineering and Technology, as well as in graduate programs. My expertise spans a wide range of disciplines, including industrial engineering, automotive mechanics, additive manufacturing, metallic and polymeric materials, finite element method, CFD (computational fluid dynamics), DOE (design of experiments), DFMA (design for manufacturing and assembly), solid and liquid waste treatment, supply chain, logistics, production planning and control, and organizational management.

Currently, I am a Professor and Researcher at Centro Universitário Senai-SP and FATEC, where I contribute to the education of new professionals and the advancement of knowledge in engineering and technology.

Possesses extensive experience in connectivity and communication, mastering protocols such as RS232, UART, SPI, I2C, Bluetooth, and WiFi, integrating hardware and smartphone applications to develop connected solutions with remote access. My experience includes project validation, assembling test jigs and conducting structural and functional tests to ensure system reliability. I work in data acquisition, including reading, storage, processing, and transmission of information, which is essential for real-time monitoring systems.

I also work on the development of IoT platforms, both local and cloud-based, covering design, dashboard creation, API integration, and data display for efficient monitoring. Additionally, I implement online task automation systems using services such as WebHooks, automated email sending, and automated trigger logic, integrating firmware for sensor reading, logical processing, data transmission, and cloud reception with remote display.

In the field of industrial networks, I design local, centralized, and distributed architectures using different transmission media (twisted pair, fiber optics, wireless) and topologies such as star, bus, and hybrid, as well as standards like LAN, WAN, and PAN. I specialize in network infrastructure, developing projects that include servers, routers, and controllers, with an emphasis on the use of protocols such as TCP/IP, Modbus, Profibus, and Profinet for communication in industrial environments.

My professional practice combines a practical and innovative approach, enabling students and developing solutions that integrate automation, connectivity, and infrastructure, aligned with the demands of Industry 4.0.
