In this experiment,the direct drying method and the drying method with fixed temperature and time were used to determine the moisture content of grains and oilseeds.Compa-ring the results of these two inspection methods,the results were showed that when the moisture of grain was below 18.0%,and the moisture of oilseeds was below 13.0%,the result by the dr-ying method with fixed temperature and time was slightly higher than the one by the direct drying method.When the moisture of grain was above 18.0%,and the moisture of oilseeds was above 13.0%,which of moisture content were determined with the drying method by two steps,the re-sult by the drying method with fixed temperature and time in the second drying was slightly high-er than the one by the direct drying method.
