Stubble drying mechanism

The utility model discloses a stubble drying mechanism, which comprises a stubble drying rack set and an air blower. The stubble drying rack set consists of an arched stubble drying rack set, the arched stubble drying rack set consists of two semi-arched stubble drying racks and is provided with an arched stubble dying face extending from the left to the right, and the air blower is disposed in the front of the stubble drying rack set. The arched stubble drying rack set enables fermenting grains to fully contact with air so as to fully oxidize reductive substances in the fermenting gains, and fermentation in the subsequent preparation process cannot be affected. Further, fresh air can be absorbed into the fermenting grains fully, so that microbial growth in the later stage can be benefited. Furthermore, the fermenting grains can be cooled in a short time using the stubble drying mechanism, so that production efficiency is improved.
