Description

Technical Field

[0001] The utility model relates to the technical field of grain drying, in particular to a grain drying device for agricultural planting. Background Art

[0002] In current agricultural production practices, grain drying is a very important link, especially in the harvest season. Drying the newly harvested grains can greatly reduce the moisture content of the grains, prevent mildew, extend the storage period, and improve the quality of the grains. However, existing grain drying equipment can usually only perform single-sided drying, which limits the drying efficiency to a certain extent.

[0003] Specifically, during the drying process, these devices can only perform one-sided drying, that is, during the drying process, only one side of the grain is exposed to the hot air for heat exchange, while the other side is blocked from the outside. The hot air cannot blow evenly to the entire surface of the grain, resulting in uneven drying of the grain. One part of the grain may still have a high moisture content, while the other part may be too dry, which will reduce the drying effect and efficiency.

[0004] In addition, since the equipment can only dry on one side, it takes more time to ensure that the grains are fully dried, which affects production efficiency. Utility Model Content
