The straw pellet production line is a method of making fuel pellets by crushing, drying and extruding straw, which can replace non-renewable fuels such as coal and oil, and has good economic, environmental and social benefits. Its principle mainly includes the following steps:
1. Straw collection and pretreatment: First, the straw needs to be collected and pretreated, including removing impurities and crushing. This can improve the efficiency of subsequent processing and ensure the quality of pellets.
2. Straw drying: If the material has a high tax content (higher than 15%), it needs to be dried using a straw dryer, usually a drum dryer.
3. Pellet forming: In the pellet machine, the straw is squeezed and subjected to high temperature and high pressure. This can cause physical and chemical changes in the polysaccharides and proteins inside the straw, making the pellets tighter and stronger.
4. Pellet cooling: The pellet fuel after forming is cooled by the cooler and then enters the burner for combustion to generate electricity or heat and heating.
Biomass pellet fuel uses waste crops as raw materials, which is energy-saving, environmentally friendly, and saves non-renewable resources, alleviating the contradiction of electricity and oil shortages. With the popularization and application of biomass fuel boilers, the demand for biomass pellet fuel will inevitably increase greatly.
