The influences of temperature and wind speed on the drying of rapeseed using cylinder drier type CD–100 were compared and the curves describing the changes of water contents under temperatures of 60 ℃, 70 ℃ and 80 ℃ and under wind speeds of 3.03 m/s, 3.80 m/s, 4.30 m/s, 4.73 m/s and 5.13 m/s were made. The result demonstrated that the drying rate of rapeseed increased with the increase of the temperature and the best drying temperature was 80 ℃. The drying rate also increased with increasing wind speed. The drying condition with drying temperature of 80 ℃ and wind speed of 4.73 m/s yielded the fastest the drying rate for rapeseed, which was 4.87%/h.
