Description

technical field [0001] The invention belongs to the technical field of drying devices for biomass raw materials, and specifically refers to a drying device for biomass fuel raw materials before processing. Background technique [0002] Biomass fuel refers to the burning of biomass materials as fuel. Generally, it is mainly made of agricultural and forestry waste such as straw, sawdust, bagasse, and rice bran. It is mainly different from fossil fuels. Directly burning biomass is a highly polluting fuel. Therefore, Generally, it needs to be processed, and after crushing, mixing, extrusion, drying and other processes, it is made into a new type of clean fuel, and then burned and utilized. The drying of biomass fuel is to ensure that it is fully burned and released. The key step is the amount of heat. When the existing biofuel raw materials are processed, most of them are dried by high-temperature evaporation, which has poor effect, and the water vapor generated during drying ne...
