Description

Technical Field

[0001] The utility model relates to the technical field of grain dryers, in particular to a grain dryer with a heat circulation function. Background Art

[0002] Food is the primary need of the people. As one of the necessities for human survival, my country attaches great importance to grain production and has designated special farmland protection areas and prohibited development, mainly to prevent food shortages. Grain is not suitable for storage after harvesting, and too much moisture in the grain will accelerate the mold and deterioration of the grain. According to relevant statistics, the proportion of grain that becomes moldy and deteriorates in my country each year is as high as about 5% because there is no time to dry the grain. Therefore, in order to prevent this kind of situation, a grain dryer for drying grain has appeared on the market.

[0003] The existing grain dryer only opens the valve to unload the grain. In order to ensure the rapid discharge of grain during the unloading process, a suction pump or additional manual participation is required. Moreover, the air carrying heat after drying will be discharged into the nature, and the heat cannot be recycled. Utility Model Content
