Abstract | The extraction of rice bran oil in a batch agitated tank showed the characteristics of a first order system. The most important factors observed for 'Saigon I' variety, which influenced the yield were temperature (T), speed of impeller (N), bran to solvent ratio (S/L), height off bottom of impeller to diameter ratio (h/d). The mass transfer coefficient and thus the rate of extraction, was affected by the speed of impeller, diameter of impeller to diameter of tank ratio, height off bottom of impeller to diameter ratio and the temperature. The general relationships developed for the yield and mass transfer coefficient were: For yield: c v o . X.s = 3.19 (Re)o.22(h/d)0.13 e-1415/T (s/L)-0.21 (d/D)-0.31 For mass transfer coefficient Ka ___.P. N = 23.68 (Re)-0.83 (d/D)1.52(h/d)-0.41 e -351/T |
