Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of biomass fuel pellet forming, in particular to a biomass fuel pellet forming machine. BACKGROUND

[0002] Biomass fuel refers to a fuel that can be used for combustion to obtain energy after biomass materials are processed.

[0003] Although the existing biomass fuel production technology is constantly improving, there are still certain limitations overall. For example, the forming technology may not be mature enough, resulting in irregular shape and uneven density of the biomass fuel, affecting the combustion efficiency and stability. At the same time, since the biomass raw materials need to be temporarily stored during mass production, the biomass raw materials that have been dried may be re-adsorbed by ash, impurities and moisture when they come into contact with air, which may affect the combustion of the biomass fuel.
