[0036] In the embodiment, when the biomass particles on the conveying belt 15 are ready to be dried, the power module 6 supplies power to the heating rod 3, and then the heating rod 3 starts to heat up. At the same time, the air inlet fan 7 is started to suck in external air into the heating frame 2.
