Abstract

This study was conducted to decide several design criterion for clean-washed rice processing system development. A Computer simulation was used to predict and analyze the mass balances and moisture changes of the process of clean-washed rice processing system. The following results were obtained from this study. 1. In order to attain the processing capacity of 1,000kg/h of the clean-washed rice processing system, that of the system was designed as 1,400kg/h which was based on the safety factor of 40% and handling capability of mass variations occurred during processing. 2. It was analyzed that the proper time required for aqueous cleaning process should be within one minute. 2. It was analyzed that the proper time required for aqueous cleaning process should be within one minute. 3. The final moisture content of clean-washed rice was controlled being 15%(w.b.) for the sake of safe storage. 4. It was proven that the optimum drying time was three minutes for the clean-washed rice dried by a rotary dryer.
