As crop waste, straw can be converted into pellet fuel with high calorific value in addition to being directly burned and returned to the field as fertilizer.
The main process of straw pellet production:
1. Collection and storage of straw
The collection, drying and storage of straw are the most difficult steps in the production process. Straw collection takes a long time (10 days to 30 days), and the collection radius of general straw is limited, so it is necessary for the project to maintain safe and efficient operations during the collection of raw materials.
2. Crushing and drying of straw
The straw passes through the pulverizer and is crushed into materials with a diameter of less than 10mm. If the moisture content of the material is greater than 20%, it needs to be dried by a straw dryer to keep the moisture content between 5% and 18%.
3. Granulation
Materials with a moisture content of 5% to 18% are granulated through a biomass pellet machine.
4. Cooling and packaging
The temperature of the granular fuel can reach 70-90°C when it is pressed out of the pellet machine, and it needs to be cooled by the cooling silo before packaging.
