During the drying process, the electric heater 8 and the blower 10 are started, and the heated heat flow enters the shunt pipe 11 through the heating pipe 9, and is evenly transported to the inside of the drying bin 1 through the shunt pipe 11 by multiple heat inlet pipes 12, so that the material in the drying bin 1 is boiling and jumping. At the same time, the induced draft fan 16 is started, and the air flow in the drying bin 1 enters the converging pipe 14 through the induced draft pipe 13, and is discharged through the exhaust pipe 17, so as to realize the drainage of the heat flow and further ensure the uniformity of drying the upper and lower layers of materials.
