Background art:

food is a living organism and water is the condition on which it depends to survive. However, the excessive water content can induce the breeding of insects and microorganisms, which easily causes the heating, fermentation, deterioration and germination rate reduction of grains. Taking grains as an example, the moisture content of the grains is 25-30% when the grains are received, and the moisture content needs to be reduced to 15% of safe moisture as soon as possible when the grains are stored. The grains in China are harvested 1-3 times a year and stored for several years. At present, the moisture of grains is mainly controlled by natural airing and drying through a grain dryer.

The natural airing is easily restricted by the influence of weather, fields and the like, and in a main production area of grains, because the yield is high and the airing field is insufficient, the moisture of the grains purchased in a grain depot often exceeds the safe moisture, which is a main factor causing the grains to mildew. In addition, even if the moisture of the grain does not exceed the safe moisture during warehousing, due to natural moisture reversion, the grain in warehousing needs to be aired regularly to ensure that the grain does not mildew. The existing grain dryer has the advantages that the grain pressed on the bottom layer is not as good as the grain drying effect on the surface layer, the drying is not uniform, and the drying effect is poor.
