The biomass pellet production line mainly includes raw material preparation, granulation processing, drying, cooling, screening and packaging.

1. Raw material preparation: The raw materials of biomass pellets mainly include straw, weeds, wood chips, sawdust and other wastes as well as energy crops such as corn straw. In the raw material preparation process, these materials need to be shredded, impurities removed and humidity adjusted to ensure the quality of subsequent granulation and drying.

2. Granulation processing: After the raw materials are processed by a granulator, granular biomass materials are formed. The main process of granulation is to heat and pressure the raw materials and press them through the mold orifice plate to form granules. The selection and operating technology of the granulator have an important impact on the quality of the granules.

3. Drying: The granulated biomass pellets contain high humidity and need to be reduced to the appropriate moisture content through drying equipment. The drying method can be hot air drying, natural air drying or other forms of heat sources. During the drying process, temperature and humidity must be controlled to avoid deformation or cracking of the particles.

4. Cooling: The dried biomass particles need to be cooled down by cooling equipment to prevent the particles from reabsorbing moisture or deforming.

5. Screening: The cooled biomass particles may have certain fragments or uneven particle sizes. The screening equipment can remove unqualified particles and improve the uniformity and quality of the particles.

6. Packaging: After screening, biomass particles can be packaged. Common packaging methods include bags, bulk, etc. Packaging should pay attention to moisture-proof, flame-proof and permeability. The production process of the biomass pellet production line can not only convert waste into resources and reduce environmental pollution, but also improve the utilization efficiency of renewable energy and reduce dependence on traditional energy.

Its specific advantages are as follows:

1. Improve energy utilization efficiency: Biomass pellets are an efficient fuel with the characteristics of high energy density and uniform combustion. The pellet fuel produced through the biomass pellet production line can replace traditional energy sources, such as coal and natural gas, and be used in heating, power generation and other fields to improve energy utilization efficiency.

2. Reduce carbon dioxide emissions: The carbon dioxide released during the combustion of biomass pellets is absorbed by plants during the growth of biomass, forming a cycle. Compared with the combustion of fossil fuels such as coal and oil, the use of biomass pellets can effectively reduce carbon dioxide emissions and has positive significance in mitigating the greenhouse effect.

3. Promote the comprehensive utilization of agricultural waste: The biomass pellet production line can convert crop straw and other waste into valuable energy, promote the comprehensive utilization of agricultural waste, and effectively solve the problem of rural waste disposal.
