-Grain Dryer Tower is often used for large-scale grain storage and suitable for drying high-quality grains such as paddy, rice, sorghum, soybean, corn, and wheat.
-Grain drying towers are mainly divided into two types: continuous type dryer tower and batch type grain dryer tower.
Continuous grain drying towers are widely used for drying large-capacity and high-moisture crops, capacity from 100ton per day to 1000ton per day in 24 hours working time.
Batch type grain dryer is widely used for small capacity paddy, seeds and oil crops drying, and can maintain the biological activity of grain to the greatest extent.
Working Principle of Grain Drying Tower
In the top drying stage of the drying tower, the high-heat air heats up the grain rapidly and takes away part of the grain surface moisture; After passing through the drying section, the material enters the slow drying section, where the inner and outer layers of the grain granules undergo moisture and heat exchange, which balances the moisture in the inner and outer layers of the material granules, which can effectively protect the grain quality;
In the medium-heat stage, moderately heated air takes away a large amount of moisture;
After the high-heat and medium-heat stages, the grain temperature increases, so the bottom drying stage uses low-heat air. The low heat air can easily take away much more water, but keep the grains from getting too hot.
Finally, the dried grain enters the cooling stage, after sufficient cooling, the grain with safe moisture and temperature can directly enter the silo for storage. For high-moisture raw material crops, a multi-stage drying and multi-stage slow drying process is usually used
