A kind of hot-blast stove using straw molded briquetting fuel has been designed. By using this drying system, a set of thin-layer drying experiment was developed. It was concluded that the designed drying system met the necessity of the maize drying characteristic and it is suitable to do the maize drying test. Drying dynamics experiment and analyses of the maize have been done at different original water containing rate. Under different temperatures and the hot-blast speeds, according to the drying curves, it showed that the most notable factor influencing the drying speed and drying quality is air temperature, and air speed sits secondly. It is also indicated that if the drying-temperature was over 60℃ especially when drying the seeds of maize, the rate of kernel cracking would increases greatly and the rate of germinate would get down out of the request of seed quality.
