Modelagem matemática da secagem da pimenta Cumari do Pará

Abstract: RESUMOObjetivou-se, neste trabalho, determinar e modelar as curvas de secagem da pimenta Cumari do Pará (Capsicum chinense Jacqui), nas temperaturas de 45, 55 e 65 ºC e estimar seu coeficiente de difusão. As pimentas foram coletadas no município de Ceres, GO, e transportadas para UEG -Anápolis, GO; a secagem foi conduzida em secador experimental com controle de temperatura e fluxo de ar de 60 m 3 min -1 m -2; os dados experimentais foram ajustados aos nove modelos matemáticos; as magnitudes do coeficiente de d… Show more

“…which the Midilli model was the one that best described the drying behavior were found for 'ceriguela' through foam mat drying (Furtado et al, 2010) and 'Cumari do Pará' pepper (Reis et al, 2011). Table 3 shows the values of the parameters of the fitted models.…”

“…Martinazzo et al (2007), in the drying of leaves of lemon grass (Cymbopogon citratus (D.C.)), observed that Midilli was the best model to describe the drying curves at temperatures from 30 to 60 ºC. In addition, Reis et al (2011), evaluating the drying of Cumari do Pará pepper (Capsicum chinense Jacqui) at temperatures of 45, 55 and 65 ºC, found that the Midilli model was the most adequate, corroborating with the present study.…”
