Introduction of Straw Dryer
Straw dryer is widely used for drying corn straw, soybean straw, cotton straw, wheat straw, sorghum straw, forage, ginkgo leaf, mulberry leaf and other agricultural cellulose materials. For small capacity requirements, it can be met by the single path rotary drum dryer, for large capacity, the three (triple) pass rotary drum dryer is recommended. The large-scale straw dryer has the advantages of high drying speed, automatic control, stable and reliable operation. Our company can also provide straw crushing and straw forming machine or straw pelleting system according to customers' needs in order to make a one-stop solution for our customers.

03
No Heat Leakage
A unique sealing structure prevents thermal energy leakage.
04
Automatic Impurity Removal
Impurities and iron are automatically removed so they do not enter the subsequent drying process.
05
Multiple Heat Sources
Customers can choose the heat source that fits their situation, and we can provide customized solutions.
06
Low Investment
Low investment, low operating cost and a short investment-recovery time.
Working Principle of Straw Dryer
Firstly, straw (crushed if needed) is transported to the rotary drum dryer by the belt conveyor. The material moves to the end of the dryer body, during which process the wet material gets fully contact with the hot air. After drying, most of the dry material is discharged through the belt conveyor. The remaining material mixed with dust goes into the cyclone dust collector and the bag dust collector in sequence, where the dust is collected. Lastly, with the function of the induced draft fan, the remaining material is discharged through the conveyor.
