Description

Technical Field

[0001] The invention relates to the technical field of biomass fuel particle forming, in particular to a biomass fuel particle forming machine. Background Art

[0002] Biomass fuel refers to fuel made from processed biomass materials that can be burned to obtain energy.

[0003] Although the existing biomass fuel production technology is constantly improving, it still has certain limitations overall. For example, the molding technology may not be mature enough, resulting in irregular shapes and uneven density of biomass fuels, affecting combustion efficiency and stability. At the same time, because biomass raw materials need to be temporarily stored when they are produced in large batches, and during temporary storage, the originally dried biomass raw materials will come into contact with the air. At this time, the biomass fuel may be adsorbed by ash, impurities and moisture again, which is easy to affect the combustion of biomass fuel.
