[0084] Further, in step S2, step S22 is executed, adjusting to the second cleaning mode, so that the preset angle is the second preset angle, and the second preset angle is 40° - 45°. Exemplarily, the second preset angle is set to 45°, moving the device forward and backward, and the scraper 1 uses a "shoveling" cleaning method on the inner wall of the blanking tower 100. At this time, the operator can gently use the device to clean the inner wall of the blanking device, which can clean most of the carbon deposits. And in this mode, cleaning water can also be sprayed on the inner wall of the blanking tower 100, and the water pressure is adjusted to improve the cleaning efficiency.

[0085] Further, in step S2, step S23 is executed, adjusting to the third cleaning mode, so that the preset angle is the third preset angle, and the third preset angle is 8° - 12°. Exemplarily, the third preset angle is set to 10°. By spraying cleaning water on the inner wall of the blanking tower 100, the inner wall of the blanking tower 100 is cleaned. At this time, the cleaning water can directly wash against the inner wall. Under the washing action of the water, the inner wall of the tower can be directly rinsed once. Especially under the lubrication of the water, the device can be used to vigorously clean the farthest part of the inner wall of the blanking device to clean the carbon deposits, so as to completely clean the inner wall.

[0086] This method can perform targeted mode adjustment according to the thickness of the carbon deposits on the inner wall and the attachment position of the carbon deposits on the inner wall, completely clean the carbon deposits on the inner wall of the blanking tower 100, significantly reduce the amount of carbon deposits falling into the cut tobacco during the production process, and improve the purity of the cut tobacco.
