[0002] Biofuel refers to solid, liquid or gaseous fuel composed or extracted from biomass, which can replace gasoline and diesel made from petroleum, and is an important direction of renewable energy development and utilization. Many biological particles need to be crushed during processing. The existing patent (publication number: CN117000394A) discloses a smashing device for biological particle fuel production and processing, which can effectively prevent the biological particle fuel that has not been fully crushed from being directly discharged from the device, prolong the time of the biological particles staying in the device, and then completely crush them. However, in actual application, the biological particles may absorb too much moisture and become damp, making it difficult to completely crush them, and they are also easy to adhere to the blades, which is not conducive to actual processing and affects the crushing quality. Therefore, we propose a biomass particle smashing device that prevents adhesion. SUMMARY

[0023] Specifically, by setting the drying cylinder in the box 1, by the feed hopper 2, the biological particles are placed in the box 1, and then the cylinder 3 is used to build a cavity in the box 1, and the heating plate 4 is used to generate heat. The heating plate 4 covering the inner wall of the cylinder 3 continuously generates heat, and the heat released by the heating plate 4 keeps the inner cavity of the cylinder 3 at a relatively high temperature, so that the biological particles just entering the box 1 are roasted at high temperature.
