In order to research the hot-air drying characteristics of red jujube,the correlative law of hot-air drying curves and drying velocity curves of red jujube are investigated at different temperature(50℃,60℃and 70℃)and air velocity(0.5 m/s, 1.0 m/s and 2.0 m/s). The experimental data is analyzed. The mathematical model of red jujube hot-air drying was established. The ARM-based automatic control system for red jujube drying were designed and implemented. The testing results of the system show that the system can meet the requirements of the temperature-humidity automatic control for red jujube drying ,and im-prove the drying quality of red jujube.
