[0002] Seeds are a special and irreplaceable means of production in agricultural production. They are the carriers for agricultural science and technology to play a role, and are the internal factors for agricultural quality, high yield, high efficiency and increased production. Seed processing is one of the many links in agricultural production and agricultural scientific research experiments, mainly including seed threshing, selection, drying, selection grading, coating and other operations. Among them, when drying the selected and washed seeds or seeds with too high water content, a blast drying oven is required.

[0003] Publication number: CN 209820077 U proposes a new type of constant temperature blast drying device for improved varieties of seeds. In this case, when the temperature probe detects that the temperature in the drying cylinder is lower than the set value, the blower and the electric heating grid net inside the heating box are controlled to be energized and run, and the external air is drawn into the blower and guided to the heating box, and is introduced into the drying cylinder after being heated by the electric heating grid net, so as to dry the seeds on the tray in the drying cylinder, and the humid air is discharged from the air outlet. When the temperature in the drying cylinder exceeds the set value, the relay A is automatically powered off to achieve constant temperature drying of the drying device. The set motor can drive the reduction gear box to rotate, and the high-speed gear box drives the tray to rotate, so that the seeds are heated evenly and the drying efficiency is improved. However, when drying the seeds, the seeds are easily stacked, resulting in uneven drying and unsatisfactory drying effect.
