The invention provides a complete production device of energy-saving high-efficiency biomass fuel particles. The device comprises a pulverizer, a dryer, a granulator and a packager. The complete production device of the energy-saving high-efficiency biomass fuel particles of the invention adopts a fast assembling structure of a large-modulus trapezoid screw thread to make template maintenance and replacement be convenient and simple. Renewable energy utilization and energy utilization efficiency improvement concepts are protruded, so heat generated in the product compression procedure in the production process is recovered, and is used for drying raw materials; and the dependence on electric energy is reduced, and energy saving and emission reduction control in the production process is reached. The single press roller structure of the plate type press roller sets of the invention is different from the single press roller structures of common granulating devices, so the static friction resistances of the press rollers, generated because of a linear velocity difference in a working state, are reduced, thereby the power consumption of the device is reduced, and energy is saved. Compared with foreign like products, the biomass fuel particles produced in the invention have the advantages of energy saving, uniform density, high energy utilization rate, and convenient maintenance.
