Resumo: This study was done to analyze the feasibility of using rotary dryers with radial air distribution, generally used for coffee processing, for corn (Zea mays L.) grain drying, based on energy consumption and drying cost. The drying air temperature was maintained at 80 or 100 °C with use of liquid petroleum gas. The drying systems consisted of a commercial and a modified rotary dryer. Corn grains with initial moisture content of about 18.6% b.u. were used in the experiment. The specific energy consumption and the consumption of fuel and electricity were determined to evaluate energy efficiency of the drying systems. The results showed lower specific energy consumption for the modified rotary dryer. The breakage susceptibility of grains was below 5%. The mean percentage of total grain cracking in the commercial dryer (SC 80 and SC 100) was 17.6% higher than that obtained with the modified dryer (SM 80 and SM 100). The mean total drying cost in the commercial dryer (SC 80 and SC 100) was lower than that of the modified dryer (SM 80 and SM 100).

Avaliou-se o consumo de energia e o custo de secagem do produto. A temperatura do ar de secagem foi controlada em 80 e 100 °C. Os sistemas de secagem foram compostos por um secador rotativo comercial e um secador rotativo modificado. Utilizou-se o GLP como fonte de energia para o aquecimento complementar do ar de secagem. O milho em grãos (Zea mays L.), com teor inicial de água de aproximadamente 18,6% b.u., foi usado no experimento. Para a avaliação da eficiência energética dos sistemas de secagem, foram determinados o consumo específico de energia, os consumos de combustível e de energia elétrica. Pelos resultados, verificou-se menor consumo específico de energia no secador rotativo modificado. A susceptibilidade à quebra do produto foi inferior a 5%. A percentagem média de trinca total do milho no secador comercial (SC 80 e SC 100) foi 17,6% superior àquela obtida com secador modificado (SM 80 e SM 100). O custo total médio de secagem no secador comercial (SC 80 e SC 100) foi menor que o obtido com o secador modificado (SM 80 e SM 100).Universidade Federal de Viçosa - UFV2010-02-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/4210.13083/reveng.v18i1.47Engineering in Agriculture; Vol. 18 No. 1 (2010); 62-76Revista Engenharia na Agricultura - REVENG; v. 18 n. 1 (2010); 62-762175-68131414-398410.13083/reveng.v18i1reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/42/38Costa, Douglas Romeude Lacerda Filho, Adílio FlauzinoSilva, Juarez de Sousa eQueiroz, Daniel Marçal deLima, Pedro NogueiraDadalto, Juliana Pinheiroinfo:eu-repo/semantics/openAccess2023-01-19T12:49:28Zoai:ojs.periodicos.ufv.br:article/42Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T12:49:28Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false
