Abstract :In this study, a laboratory dryer is used for eggplant drying process and moisture content at any drying time were compared by Newton, Page, Modified Page, Henderson and Pabis, Logaritmic, two-term, two-term exponential, Wang and Singh, Thompson, difusion approximation, Modified Henderson and Pabis, Verma et al., Midilli et al. models. The effect of drying air temperature and velocity on the coefficients of the best suited model were determined by multiple regression method. Root mean square error (RMSE) and khi squre (X2) were used for the determination of the best suitable drying model. Modelling efficiency (EF) was determined. According to the results, The effects of drying air tem-perature (T) and velocity (V), could be predicted by the Midilli et al. (MR=a.exp(-k.t)+b.+t)) with contants and coeffi-cients a=[0.7889+0.050.ln(T)], k={(11.0023+3.1720.ln(T)}, n=[1.0204.exp(1.0580/T)], b=0.0005.exp(0.0877/V) for 6 mm and a=[0.9853+0.0264.ln(T)], k=-(0.7517+0.2964.ln(T)), n=[0.6899.exp(0.3403/T)] b=0.0025.exp(0.1738/V) for 9 mm. Modeling efficiency (EF) changed between 0,998300…0,999123 for 6 mm and changed between 0,998684….0,999188 for 9 mm.Keywords : Patlıcan, Hava sıcaklığı, Hava hızı, modelleme, modelleme yeterliliği
