Análise crítica do sistema de recepção de grãos na indústria arrozeira em Itaqui-RS

Abstract

The critical analysis of the grain reception system in the rice industry in Itaqui-RS aimed to identify and compare the quality of different varieties of rice grains. The problem addressed was the variability in grain quality, which affects the reception and storage process. The justification for the study lies in the need to optimize grain quality and increase process efficiency. The results showed that variety 424 presented moderate moisture and high variability in impurities. Although it performed well in whole grains and total income, there were significant variations in broken grains and defects such as stained/chopped and plastered grains. Variety 431 stood out for its more consistent moisture and high percentage of whole grains and total yield, but exhibited variability in broken grains and a higher incidence of plastered grains. The N.I. variety showed greater variation and average moisture and impurities, good performance in whole grains and total yield, but high incidence of stained/chopped and plastered grains. To optimize grain quality, it is recommended to improve humidity control, especially for the N.I. variety, where humidity is higher. It is necessary to reduce impurities in the 424 variety and adjust equipment and handling processes to minimize broken grains. Strict monitoring is also essential to reduce the incidence of stained/chopped and plastered grains, especially in the 431 variety. Adopting these measures can significantly improve grain quality, increasing process efficiency and consumer satisfaction.
