Low-cost preparation device for biomass charcoal production

The utility model relates to the field of biomass charcoal, in particular to a low-cost preparation device for biomass charcoal production, which comprises a casing, the inner wall of the casing is fixedly connected with a heating plate, and the top of the casing is movably connected with a cover plate. According to the low-cost preparation device for biomass charcoal production, a heating plate can heat the interior of the machine shell so as to achieve the baking effect, and an air valve is used in cooperation with an exhaust pipe and an air draft plate so that moisture generated in the machine shell due to baking can be rapidly discharged; the motor can drive the rotating shaft to rotate so that the smashing disc can smash the biomass raw materials, the grinding roller can conduct secondary grinding on the smashed biomass raw materials, and the screen can filter smashed biomass raw material particles. Through the independent device, the two-way functions of baking and smashing are achieved, so that the ove
