Incidência de defeitos em grãos de arroz ao longo do ano em armazenamento em silos metálicos – um estudo de caso em indústria de grande porte

Abstract

Most of the grains received by the rice processing industries will only be used in the coming months after receipt; for this reason, many loads are stored in silos until they are used for processing and subsequent packaging and then proceed to market. During this period of storage, there is a need for sanitary and environmental controls, especially temperature and humidity, because, in addition to the risk of contamination by insects, environments with high temperature and high humidity are conducive to the development of insects and microorganisms, such as fungi, these cause yellowing and other forms of grain degradation, which can make them unsuitable for human consumption, causing significant losses for industries. The aim of this work, elaborated with Case Study Methodology, was to monitor the incidence of these changes in temperature and internal humidity of the silos in silos equipped with forced aeration systems and to evaluate their effects on the quality of the grains during the agricultural years. 2019/2020 and 2020/2021, in a large industrial processing plant located in Pelotas, south of Rio Grande do Sul. The results show variations in the incidence of defects in the other months of the year.
