The contact time between the powder and the hot air is increased through the spiral conveying tube 34 to improve the drying effect. Finally, the hot air is discharged from the mounting interface 35 in the other second socket 82, and then enters the spiral sedimentator for the next processing to perform gas-solid separation and realize drying of the materials. In order to ensure the drying effect of the materials during the processing, the electric heating rod 37 can also be driven to heat the heating cylinder 33, thereby conducting heat to heat the spiral conveying tube 34 and recovering heat energy for utilization. During cleaning and maintenance, the docking plate 23 can be removed, and the relatively matching first processing shell 21 and the second processing shell 31 can be disassembled to obtain a smaller volume for cleaning; and the top cover 24 and the cover plate 32 can be disassembled, and the second processing shell 31 can be separated from the bracket 25 for complete disassembly, which is helpful for cleaning the inner wall.
