It can be directly burned. In the production and processing of biomass fuel, a quick drying device is required to dry the raw materials, remove moisture from the raw materials, and make the raw materials dry for easy combustion.

[0003] After searching, the Chinese patent application No. 202320623927.5 discloses a rapid drying device for biomass fuel. The utility model includes a base, a shell is provided above the base, a rotating shaft is rotatably installed in the shell, and a conveying blade is welded on the outer surface of the rotating shaft; a sealing shell is installed on the upper end of the outer surface of the shell, and an electric heating plate connected to an external power supply is installed in the sealing shell; a through hole is opened on the outer wall of the shell and located in the sealing shell, and a stirring plate is welded on the conveying blade. Under the action of the electric heating plate, the outside air can be heated, and the heated air flows into the shell through the through hole, so that the biomass particles in the shell can be heated and dried.
