[0018] The essential features and advantages of the present invention are further described below in conjunction with examples, but the present invention is not limited to the examples listed.

[0019] like Figures 1 to 4As shown, a rice drying device of this embodiment includes a cylinder 1 and a driving assembly 2. The driving assembly 2 is connected to the cylinder 1 to drive the cylinder 1 to rotate, so that the material in the cylinder 1 is turned over. A heating device 3 is provided below the cylinder 1. The heating device 3 generates heat to heat the material in the cylinder 1. The heating device can adopt electric heating, infrared heating and other devices in the prior art, and its function is to generate heat. The cylinder 1 is arranged between the first support plate 4 and the second support plate 5. The first support plate 4 is provided with a through hole 41 connected to the accommodating cavity 11 of the cylinder 1. The first support plate 4 is provided with a hopper 6 connected to the through hole 41. The material enters through the hopper 6 and enters the cylinder 1 through the through hole 41. The feed pipe 61 of the hopper 6 is respectively connected to the suction assembly 7 and the through hole 41. The airflow in the cylinder 1 can be output through the through hole 41 and the feed pipe 61 through the suction assembly 7. The suction assembly 7 includes a fan 71, an air extraction pipe 72 and an exhaust pipe 73. The air extraction pipe 73 is connected to the fan 71 and the feed pipe 61 respectively, and the exhaust pipe 73 is connected to the fan 71 and the material receiving barrel 74. The first support plate 4 is provided with a discharge port 42, and the discharge port 42 has a material blocking assembly 43. When the cylinder 1 rotates, the material blocking assembly 43 seals the discharge port 42 to prevent the material from falling out. When discharging, the material blocking assembly is opened. In the above technical scheme, the material is input into the cylinder 1 through the hopper 6, and the cylinder 1 rotates and dries the material through the heating device 3. At the same time, the dust in the cylinder 1 is sucked by the fan 71 to reduce the impurities in the material. The airflow passes through the through hole 41, the feed pipe 61 and the air extraction steel pipe 72, passes through the fan 71 and enters the exhaust pipe 73, and then enters the material receiving barrel 74 for collection. A dust filter or filter bag can be set in the material receiving barrel 74. Through the above technical scheme, the dust impurities in the material can be removed when the material is dried, and the impurity content can be reduced.

When the arc hole 762 is misaligned with the air hole 741, the air hole 751 is closed, and the suction negative pressure is the maximum at this time. When the arc hole 762 coincides with the air hole 741, the air hole 741 is opened, and the external air enters the fan at this time, and the suction negative pressure is reduced. Through the above technical solution, it is easy to adjust the suction negative pressure.
