In the district of Cabanaconde, maize agricultural production faces significant challenges due to the lack of efficient grain processing methods. This study introduces the design and implementation of a corn grain cleaning and sorting machine capable of processing 150 kg/h, aimed at enhancing productivity efficiency and grain quality at Peruanita company. Through a methodology that includes needs analysis, mechanical design, and prototype evaluation, a system combining threshing, cleaning, and sorting technologies was developed. The results showed a significant increase in productivity and a reduction in processing time, with operability that respects grain quality standards. The conclusions underline the importance of integrating technological solutions in agriculture to meet efficiency and sustainability challenges, highlighting the potential of this machine to be replicated in other regions with similar challenges.
