Co-counter current corn drying tower is continuous drying operation. The tower is installed outside. The drying tower is composed by storage layer, drying layer, tempering layer, cooling section, grain discharging mechanism, urgent grain unloading mechanism, tower frame, heat air intake mechanism, moisture exhaust mechanism, heat air blower mechanism, cooling fan mechanism, needed motor and other components. Commonly used in large-scale grain storage project. Apply to variety grain high-quality drying, such as paddy rice, sorghum, soybeans, corn and wheat etc.
In the top drying stage , high-heat air made grain rapid warming, and took away part of granule surface moisture.
Medium-heat stage takes away large amounts of moisture with medium heated air.
After high-heat and medium-heat stage, the grain granule temperature has raised, so bottom drying stage use low-heat air. Low-heat air can easily take away stronger grain inside moisture but avoid grain temperature too high.
At last, dried grain come to cooling stage, after enough cooling, grain with safety moisture and temperature can comes to silo storage directly.
