Thin-Layer Drying of Bay Laurel Leaves (Laurus nobilis L.)

摘要: In this work, bay laurel leaves were dried using pilot-scale, cabinet-type, convective dryer. Drying experiments conducted constant air velocity of 2 m/s and temperatures 50, 60 70C. rate increased with increase in temperature thus reduced the drying time. The experimental data applied to 14 thin-layer models. Nonlinear regression analysis was performed relate parameters model conditions. performance these models is evaluated by comparing R 2, χ2 RMSE between observed predicted moisture ratios. Among all models, Midilli et al.'s found be best for explaining characteristics leaves. effective diffusivity ranged from 9.38 × 10−12 2.07 × 10−11 m2/s over range studied, activation energy 36.48 kJ/mol leaves. Practical Applications Drying most important process preserve agricultural products, because it has a great effect on quality products. objective foods reduction content level that allows safe storage an extended period. Bay plants are known cosmetic industry, food medicinal purposes. This study concerns investigation presents mathematical
