When the driving motor 12 drives the stirring shaft 5 to rotate, the stirring blade 11 can fully stir the material in the first container 1, so that the material is stirred continuously.
It should be noted that, in this embodiment, the first cover 6 is provided with a feeding port and a material taking port, and the material is added into the first container 1 through the feeding port, and the material is taken out from the first container 1 through the material taking port. In order to conveniently feed and take materials, the output shaft of the driving motor 12 can be detachably connected with the top end of the stirring shaft 5, when the materials are required to be fed and taken, the output shaft of the driving motor 12 is separated from the top end of the stirring shaft 5, and then the first cover body 6 is taken down to feed or take the materials.
In this embodiment, the stirring shaft 5 is hollow, the top end of the stirring shaft 5 is closed, the bottom end of the stirring shaft 5 is open, the air outlet of the suction fan 4 is communicated with the bottom end opening of the stirring shaft 5 through a rotary joint, and the top end of the first cover body 6 is provided with a first ventilation opening 8; the side wall of the stirring shaft 5 is provided with a plurality of drying openings 13 communicated with the cavity in the stirring shaft 5, the suction fan 4 is used for sucking hot air into the stirring shaft 5, and the hot air finally blows out through the drying openings 13 on the side wall of the stirring shaft 5 after reaching the stirring shaft 5.
In the present embodiment, the first container 1 and the suction fan 4 are both disposed in the second container 2, and the suction fan 4 is located below the first container 1; the bottom end of the first container 1 is connected to the bottom plate of the second container 2 by at least three support bars.
