The objective of this study was to evaluate the effects of the wind exhaustion system (with and without natural lighting) during soybean storage (0, 3, and 6 months) on energy cost, mass temperature, mass loss, and soybean quality. During storage, the silo without exhaustion required more hours of aeration (191 h), higher energy consumption (9550 kW), and showed higher reduction in moisture content (2.07%) and loss of mass (105 t), when compared to silos with exhaustion and light and with exhaustion and no light. Fermented and moldy defects increased during storage, with a higher incidence of mold in the silo with exhaustion and no light when compared to the silo without exhaustion. Germination and soluble protein decreased during storage, but no difference was observed between silos. The acidity increased during storage, with the higher acidity being found in the silo with exhaustion and light when compared to the silo without exhaustion. The silo with exhaustion and light had an increase in electrical conductivity during storage, however, the lower electrical conductivity in 6 months was observed in the silo without exhaustion. The yellow coloration (b*-value) and the luminosity (L*-value) of the grains decreased during storage in silos with exhaustion and light and in the silo with exhaustion and no light. All silos had good conservability during storage, with acceptable values in all analyzed parameters. The excess of aeration promoted the soybean drying to safer levels of storage in the silo without exhaustion, however, the cost of storage was higher in that silo.

本研究的目的是评估大豆储存期间（0、3 和 6 个月）的风耗系统（有和没有自然照明）对能源成本、质量温度、质量损失和大豆质量的影响。在储存过程中，没有耗尽的筒仓需要更多的曝气时间（191 小时）、更高的能耗（9550 千瓦），并且与有排气的筒仓相比，水分含量降低（2.07%）和质量损失（105 吨）更高。精疲力竭而轻，精疲力竭而无光。储存期间发酵和发霉的缺陷增加，与没有耗尽的筒仓相比，在耗尽和没有光的筒仓中霉菌的发生率更高。储存期间发芽和可溶性蛋白质减少，但在筒仓之间没有观察到差异。储存过程中酸度增加，与没有筋疲力尽的筒仓相比，在筋疲力尽和光线充足的筒仓中发现了更高的酸度。枯竭和光照的筒仓在储存期间电导率增加，然而，在未枯竭的筒仓中观察到在6个月内电导率降低。黄色（b*值)和光度( L*值)在枯竭和光照的筒仓中和在枯竭和不光照的筒仓中均降低。所有筒仓在储存过程中都具有良好的可保存性，所有分析参数均具有可接受的值。过度曝气促进了大豆在筒仓中干燥到更安全的储存水平而不会耗尽，但是，该筒仓的储存成本更高。
