Description

Technical Field

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

[0002] The word "cereal" has a broad meaning and can include many kinds of grains, such as rice, wheat, millet, soybeans, etc., as well as some other grains. Cereals are made up of the seeds and fruits of these plants. But before storage, we need to process these grains because they contain a lot of water, so we need to separate the water before we can preserve them.

[0003] In grain drying equipment, the main component is the drying box. These equipment usually include facilities to generate hot air. During use, the grains are laid flat in the drying box and then heated by the hot air to complete the drying process. However, there is a problem with this method, that is, since the grains remain stationary for a long time, the heat distribution between them is not uniform, which may affect the drying effect of the grains. In addition, the water vapor generated during the drying process can easily condense into water on the top of the drying box and drip again, which has a great impact on the drying efficiency.

[0004] To this end, we propose a drying device for agricultural grain processing. Utility Model Content
