Resumo: 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.

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.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraSales, Luiz Carlos de OliveiraSilva, Walter Rodrigues daCavariani, Cláudia1999-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5546Pesquisa Agropecuaria Brasileira; v.34, n.11, nov. 1999; 2097-2108Pesquisa Agropecuária Brasileira; v.34, n.11, nov. 1999; 2097-21081678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5546/2737info:eu-repo/semantics/openAccess2010-07-07T19:44:17Zoai:ojs.seer.sct.embrapa.br:article/5546Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-07-07T19:44:17Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
