Environmental conditions in hot and humid climates are highly unfavorable for grain storage, often leading to pest infestations that can cause irreversible damage to the stored product. This study evaluated the effects of compressor and blower rotations on the psychrometric properties of air in a cooling system designed for grain storage. Conducted in Dourados, Mato Grosso do Sul, Brazil, the experiment utilized an Autonomous System for Cooling and Psychrometric Control of Grain Storage Conditions (SIARCONPAG), which adjusts exit air conditions to maintain the hygroscopic balance of grains in tropical environments. Tests were performed in three different operating modes, varying the temperature and relative humidity of the inlet air. Results showed that compressor and blower rotations significantly affected the temperature and relative humidity of the output air. The system, tested under controlled conditions, reduced the average storage temperature by up to 5 °C and maintained relative humidity between 60-65%, which is ideal for grain preservation. The system’s energy consumption was optimized, achieving 20% greater efficiency compared to traditional cooling systems. SIARCONPAG effectively manipulated psychrometric air conditions, with the isothermal humidifier and secondary condenser adapting to both low and high humidity levels. The results suggest that the system provides an efficient solution for controlling grain storage conditions in tropical regions, reducing post-harvest losses and contributing to food security. This study advances the development of grain storage technologies and supports more sustainable agricultural practices.
