Resumo: Drying is widely used to control and maintain the quality of agricultural products. Thus, this study aimed to analyze the dry quinoa and adjust existing mathematical models to experimental moisture ratio values. The study was conducted between April and August 2014. The initial water content was between 28.32 and 27.48% d.b., being subjected to drying in an oven with forced air circulation, at temperatures of 40, 50, 60 and 70 °C to achieve water levels between 8.94 at 5.76% d.b. Thirteen mathematical models were fitted to experimental data. We considered the magnitude of the coefficient of determination (R²), mean relative error (P) and the estimated standard deviation (SE), and also the ease of use of the model. Based `on these results, it was concluded that models Page, Midilli and Logarithmical showed the most satisfactory statistical coefficients to describe quinoa drying curves at all temperatures studied. Page model was selected to describe the quinoa drying curves for simplicity.

Com este estudo se objetivou analisar a secagem de grãos de quinoa e ajustar modelos matemáticos existentes aos valores experimentais de razão do teor de água. Este estudo foi realizado entre Abril e Agosto de 2014. O teor de água inicial variou entre 28,32 e 27,48% b.s., sendo os grãos submetidos a secagem em estufa com circulação forçada de ar nas temperaturas de 40, 50, 60 e 70 °C, até atingirem teores de água entre 8,94 a 5,76% b.s. Treze modelos matemáticos foram ajustados aos dados experimentais. Foram consideradas as magnitudes do coeficiente de determinação (R2), erro médio relativo (P) e do desvio padrão da estimativa (SE), e ainda a facilidade de uso do modelo. Com base nos resultados obtidos, concluiu-se que os modelos de Page, Midilli e Logarítmico foram os que apresentaram coeficientes estatísticos mais satisfatórios para descrever as curvas de secagem de quinoa, em todas as temperaturas estudadas. O modelo de Page foi selecionado para descrever as curvas de secagem de quinoa devido a simplicidade de uso.Universidade Federal de Viçosa - UFV2017-11-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/69510.13083/reveng.v25i4.773Engineering in Agriculture; Vol. 25 No. 4 (2017); 318-325Revista Engenharia na Agricultura - REVENG; v. 25 n. 4 (2017); 318-3252175-68131414-398410.13083/reveng.v25i4reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/695/463Moscon, Eder StolbenMartin, SamuelSpehar, Carlos RobertoDevilla, Ivano AlessandroJunior, Francisco Rodolfoinfo:eu-repo/semantics/openAccess2023-01-19T13:32:57Zoai:ojs.periodicos.ufv.br:article/695Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:32:57Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false
