Abstract: High temperature and high humidity drying of artificially formed rice was studied in the present paper. Results indicated that drying rate was speedy during the high temperature and high humidity drying stage with fewer contraction caused by less water gradient. Oxidative rate of oil that might be caused by ranciodity could be controlled greatly because of less O2 in the air. Flavor of rice be coald retained better as less loss of flavor material by this drying method. Final product had good color and transparency and the rice was elastic after rehydration of 3-5min dae to the better gelatinization. Optimum drying conditions were preheat 5min,temperature 90℃,relative humidity 25%,air speed 2.8m/s.The earlier drying stage temperature was 90℃,relative humidity 60%,drying 15min and the later drying stage temperature 60℃,relative 25%,drying 15min.Air speed was 2.5m/s.
