[0002] Biomass fuel is a renewable energy source, usually referring to the production of energy from plant, animal or organic waste, such as wood, crop residues, urban garbage, etc. These materials can be converted into fuels through different methods, such as biomass fermentation, compression, gasification, etc., and used in power generation, heating, transportation and other fields. In the production and utilization of biomass fuels, the raw materials may be uneven. By stirring, these raw materials can be fully mixed to ensure the quality and performance of the fuel, and at the same time help improve the combustion efficiency and energy utilization of the fuel.

[0003] The existing production of biomass fuel is mostly done by cutting first and then stirring. In most cases, the cutting is not complete, and the incompletely cut biomass fuel may affect the subsequent stirring process. Moreover, most biomass fuels contain water, and the water contained in them is usually squeezed out during the stirring process of the processing stirring device, making the raw materials after stirring wet, and the biomass fuels may stick to each other, resulting in uneven stirring. Therefore, in order to solve the above problems, the present application provides a biomass fuel stirring device.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
