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 insert ignore into journalissuearticles values(RMSE); and khi squre insert ignore into journalissuearticles values(X2); were used for the determination of the best suitable drying model. Modelling efficiency insert ignore into journalissuearticles values(EF); was determined. According to the results, The effects of drying air tem-perature insert ignore into journalissuearticles values(T); and velocity insert ignore into journalissuearticles values(V);, could be predicted by the Midilli et al. insert ignore into journalissuearticles values(MR=a.expinsert ignore into journalissuearticles values(-k.t);+b.+t);); with contants and coeffi-cients a=[0.7889+0.050.lninsert ignore into journalissuearticles values(T);], k={insert ignore into journalissuearticles values(11.0023+3.1720.lninsert ignore into journalissuearticles values(T);}, n=[1.0204.expinsert ignore into journalissuearticles values(1.0580/T);], b=0.0005.expinsert ignore into journalissuearticles values(0.0877/V); for 6 mm and a=[0.9853+0.0264.lninsert ignore into journalissuearticles values(T);], k=-insert ignore into journalissuearticles values(0.7517+0.2964.lninsert ignore into journalissuearticles values(T););, n=[0.6899.expinsert ignore into journalissuearticles values(0.3403/T);] b=0.0025.expinsert ignore into journalissuearticles values(0.1738/V); for 9 mm. Modeling efficiency insert ignore into journalissuearticles values(EF); changed between 0,998300…0,999123 for 6 mm and changed between 0,998684….0,999188 for 9 mm.
