NOVELTY - A biomass fuel is manufactured by selecting agricultural resource, poultry manure, organic wastewater, and solid organic waste, crushing solid organic fertilizer at greater than or equal to 10000 rpm for 3 minutes, crushing agricultural resource at greater than or equal to 6000 rpm for 3 minutes, crushing poultry manure at greater than or equal to 3000 rpm for 3 minutes, crushing organic waste at greater than or equal to 2400 rpm for 3 minutes, mixing organic solid waste, agricultural resource, poultry manure, and organic wastewater at 40-60 degrees C for 30-40 minutes, draining and extruding mixed material in extruding device to reduce moisture and volume, and drying at 50-70 degrees C.    USE - Manufacture of biomass fuel (claimed).    ADVANTAGE - The fuel has low pollution, carbon content, smoke dust, and high combustion rate, is energy-saving and environment-friendly, avoids use of high cost energy, and increases energy usage efficiency.    DETAILED DESCRIPTION - A biomass fuel is manufactured by selecting agricultural resource, poultry manure, organic wastewater, and solid organic waste in which agricultural resource is firewood, wood, methane, rice hull, tree bark, grass, corn rice core, corn core, rice straw, wheat straw, peanut shell, sugarcane dreg, and cottonseed hull, and organic wastewater is domestic wastewater, alcohol wastewater, sugar wastewater, pharmaceutical wastewater, and paper-making wastewater, crushing solid organic fertilizer at greater than or equal to 10000 rpm for 3 minutes, crushing agricultural resource at greater than or equal to 6000 rpm for 3 minutes, crushing poultry manure at greater than or equal to 3000 rpm for 3 minutes, crushing organic waste at greater than or equal to 2400 rpm for 3 minutes, sequentially mixing organic solid waste, agricultural resource, poultry manure, and organic wastewater at 40-60 degrees C for 30-40 minutes, draining and extruding mixed material in extruding device to reduce moisture and volume, and drying at 50-70 degrees C until water content is less than or equal to 25%.
