[0026] When using the present device, the staff first starts the first motor 4 to drive the first rotating shaft 5 to rotate, thereby driving the biomass particles to be stirred and at the same time driving the spiral auger 8 fixedly mounted on the first rotating shaft 5 to rotate, which not only reduces the occurrence of agglomeration of biomass particles inside the storage bin 3 but also reduces the occurrence of blockage when the biomass particles enter the screening bin 2 through the discharge port 7.
