[0002] Corn producers tend to start harvesting early, and its moisture content is high. In order to reduce accumulation losses, corn producers start harvesting early and extend the harvest period under good climatic conditions. Although the corn can be dried quickly and naturally in the field after the top is cut off, it still cannot reach the dryness that can be preserved for a long time. Drying operations usually use sun exposure, but this operation depends on the weather, which affects the drying speed. In addition, when encountering sudden rain, it is often too late to collect the corn, causing the corn to mold. Therefore, people gradually choose to use corn kernel dryers to dry corn.

[0003] However, the existing corn kernel dryer has the following problems: in order to dry quickly and evenly, the corn kernels need to be turned over. The existing dryer uses a vibrating screen for turning, which is not suitable for drying a large number of corn kernels. The dryer body temperature is high, and the corn kernels in contact with the dryer body are easily burnt, affecting the quality. There are also a lot of impurities and dust in the corn kernels. Direct turning and drying will produce a lot of dust that cannot be effectively handled.
