Abstract

This work presents the effective optimum parameters of one rotary dryer such as energy consumption, optimum drying time, color and size distribution of outlet sodium chloride crystals from dryer and the amount of distilled water. The experimental results show, the maximum deviation between salt production in 12 minutes as drying time and production of dried saline crystals in 15.2 minutes is only 8% but since of the quality of outlet dried saline crystals is optimized in 15.2 minutes so this drying time is introduced as optimized time for drying. Also, the moisture content (kg) per dried salt (kg) in this condition is 0.005. According to the literature, this amount of moisture content in outlet dried saline crystals is very suitable.
