Drying of soybean seeds in a radial air flow dryer. I. Physical monitoring
The purpose of this research was to study several physical parameters of soybean seed drying submitted to stationary process with radial air distribution by combining different air flows (26.9, 28.4 and 33.2 m3/minute/ton) and temperatures (42, 46 and 50oC), considering seed positions in the seed mass (17, 34 and 51 cm in relation to the insuflation cylinder) and drying periods (zero to twelve hours with two-hour intervals). Environmental air, insuflation air, seed temperatures, moisture content of seeds, drying speed and drying curves were characterized. Considering the evaluated parameters during the drying process, the physical advantages of the combination of 28.4 m3/minute/ton with 46oC, and the desadvantage of the combination of 26.9 m3/minute/ton with 42oC were observed.

O trabalho foi desenvolvido com o objetivo de avaliar a evolução física do processo de remoção de água das sementes em secador estacionário, com cilindro central perfurado e distribuição radical de ar. A pesquisa foi conduzida com sementes de soja, variando o fluxo (26,9, 28,4 e 33,2 m3/minuto/t) e a temperatura do ar insuflado (42, 46 e 50oC), considerando a posição das sementes (17, 34 e 51 cm em relação ao cilindro de insuflação) e o tempo de secagem (zero a doze horas, com intervalos de duas horas). Foram caracterizados o ar ambiente, o ar insuflado, as temperaturas e os teores de água da massa, as velocidades e curvas de secagem. As avaliações realizadas destacaram vantagens físicas operacionais da combinação de 28,4 m3/minuto/t com 46oC e o contrário, com a combinação de 26,9 m3/minuto/t com 42oC.
