Automação do sistema de aeração em silos protótipo

Abstract

Aeration is an essential practice in maintaining the quality of agricultural products, as it helps control the grains temperature, preventing the development of agents that could cause product deterioration, loss of quality, and value. Implementing automation in this operation brings significant benefits, reducing post-harvest losses and improving the stored product quality conservation. It is a technique that allows real-time monitoring with precision, aiding in decision-making. Thus, the objective of this study was to adapt and update the thermometry and hygrometry control system for the automation of the aeration and air moistening system through a chamber containing expanded clay saturated with water in prototype metal silos. The study presents two prototype silos named "conventional silo" and "humierated silo." In the system validation, four scenarios with different aeration activation schedules, named "Scenario 1," "Scenario 2," "Scenario 3," and "Scenario 4," were tested. Data collection for the experiment took place from August 22, 2022, until November 3, 2022. The data collected by the system were stored on an SD memory card and subsequently uploaded to the cloud. The results obtained from the experiment demonstrated that the system update favored the quality and quantity of data obtained for decision-making regarding aeration.
