Resumo: | The seed separation based on aerodynamical properties can be carried out to remove poor nourished or empty seeds and impurities. Air separation can be used alone or in conjunction with other separation as in air screen cleaner or gravity table separators. Among equipment there is the continuous flowing blower that uses only a vertical air stream to perform seed cleaning. So, the aim of this study was to evaluate the continuous seed blower with vertical air stream on barley, crimson clover and wheat seeds cleaning and quality upgrading. Seed samples of each specie were prepared and moisture content determined. The samples were blown at following air velocities: 6 m.s-1 to 14 m.s-1 (barley), 8 m.s-1 to 13 m.s-1 (crimson clover) and 8 m.s-1 to 13 m.s-1 (wheat), in 1 m.s-1 intervals. Physical purity, the thousand seed weight and the physiological quality (germination and vigor) were quantified. It was conclude that: 1 - it is possible to cleaning barley, crimson clover and wheat seeds and quality upgrading seed lots in a continuous flowing blower with vertical airstream; 2 - the air velocity 9, 10 and 11 m.s-1 where adequate to cleaning and quality ugrading barley, crimson clover and wheat seeds, respectively in the continuous flowing blower, considering seed physical purity, germination and vigor and acceptable seed discharge percentage; 3 - there is an horizontal air velocity gradient in the continuous flowing blower plastic tube; 4 - the voltage affect the air velocity in the plastic tube at low fan velocities in the continuous flowing blower with vertical airstream. |

A separação pelo ar pode ser utilizada isolada ou em conjunto com outras separações como no caso da máquina de ar e peneiras ou da mesa de gravidade, por exemplo. Dentre os equipamentos para separação utilizando apenas ar encontra-se o soprador contínuo com fluxo vertical de ar. Assim, o objetivo desse trabalho foi avaliar o soprador contínuo com fluxo vertical de ar na limpeza de sementes de cevada, trevo encarnado e trigo e no aprimoramento da qualidade fisiológica. Após a preparação das amostras de cada espécie, estas foram submetidas ao soprador regulado para velocidade do ar de 6 m.s-1 a 14 m.s-1 (cevada), 8 m.s-1 a 13 m.s-1 (trevo encarnado) e 8 m.s-1 a 13 m.s-1 (trigo), em intervalos regulares de 1 m.s-1. Avaliou-se a pureza física, o peso de mil sementes e a qualidade fisiológica. Concluiu-se que: 1 - é possível limpar sementes de cevada e trigo e aprimorar a qualidade dos lotes, utilizando soprador contínuo com fluxo vertical de ar; 2 - as velocidades do ar 9, 10 e 11 m.s-1 foram adequadas para a limpeza e aprimoramento da qualidade de sementes de cevada, trevo encarnado e trigo respectivamente em soprador continuo com fluxo vertical de ar, considerando a pureza física, germinação e o vigor e porcentagem de descarte de sementes aceitável; 3 - ocorre um gradiente horizontal da velocidade do ar no tubo plástico do soprador contínuo; 4 - a voltagem interfere na velocidade do ar no tubo plástico vertical em baixas velocidades do ventilador em soprador contínuo com fluxo vertical de ar.application/pdfporUniversidade Federal de PelotasPrograma de Pós-Graduação em Ciência e Tecnologia de SementesUFPelBRFaculdade de Agronomia Eliseu MacielSementesHordeum vulgareTrifolium incarnatumTriticum aestivumVelocidade terminalQualidade fisiológicaSeedsHordeum vulgareTrifolium incarnatumTriticum aestivumTerminal velocityPhysical qualityPhysiological qualityCNPQ::CIENCIAS AGRARIAS::AGRONOMIAUso de soprador contínuo com fluxo vertical de ar em sementes de cevada, trevo encarnado e trigoUse of continuous flowing blower with vertical air stream in barley, wheat and crimson clover seedsinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFPel - Guaiacainstname:Universidade Federal de Pelotas (UFPEL)instacron:UFPELORIGINALtese_suemar_avelar.pdfapplication/pdf1994897http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/1403/1/tese_suemar_avelar.pdf7caae4c2c8711db573bbdc53ac395a0fMD51open accessTEXTtese_suemar_avelar.pdf.txttese_suemar_avelar.pdf.txtExtracted Texttext/plain214893http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/1403/2/tese_suemar_avelar.pdf.txtbf3a53f14c2890c23b9b66c11bb3848fMD52open accessTHUMBNAILtese_suemar_avelar.pdf.jpgtese_suemar_avelar.pdf.jpgGenerated Thumbnailimage/jpeg1329http://guaiaca.ufpel.edu.br/xmlui/bitstream/123456789/1403/3/tese_suemar_avelar.pdf.jpg2d685c7d549b5673d4e9909736f11183MD53open access123456789/14032016-09-27 16:06:06.512open accessoai:guaiaca.ufpel.edu.br:123456789/1403Repositório InstitucionalPUBhttp://repositorio.ufpel.edu.br/oai/requestrippel@ufpel.edu.br || repositorio@ufpel.edu.br || aline.batista@ufpel.edu.bropendoar:2016-09-27T19:06:06Repositório Institucional da UFPel - Guaiaca - Universidade Federal de Pelotas (UFPEL)false |
