Desenvolvimento de protótipo de biodigestor de pequeno porte com implementação de recursos para melhoria de eficiência

Abstract

The present work consists of the development of a prototype of biodigestor that is able to keep it operating in ideal conditions, thus making its service reach its real potential. Studying the literature and using the biodigestor installed in the Embrapa Gadode Leite experimental field, located in the city of Coronel Pacheco, Minas Gerais, as a real model for study and observation, it was possible to reach your critical needs that were the focus of the development of the prototype improvements. , the control of the internal temperature of the biodigester and the agitation of the material, also inside it. Therefore, a propeller mixer responsible for the agitation of the material was fully manufactured, in addition to the development of a reading and temperature control system, ensuring that this parameter remains within an optimal range of operation, both systems being automated and controlled by Arduino. The manufacturing phase has been completed, functional tests and pre-assembly have been completed and the prototype is installed on a small property for validation of operation and efficiency analysis.
