[0027] In the production process of traditional stem washing machines, cold water is first injected into the water tank of the stem washing machine, which is heated by steam. The water temperature is kept within a certain range through a temperature control system, and the heated warm water is sent to the washboard water tank at a certain flow rate through a circulating water pump. The tobacco stems are quantitatively fed and transported to the conveyor belt through the washboard water tank vibrating conveyor. The tobacco stems floating on the water surface are transported to the belt through the flow of water. In this process, the temperature and moisture content of the tobacco stems are increased, the tobacco dust and sand are washed away, and the debris with a larger specific gravity sinks to the bottom of the water tank.

[0028] Based on this, traditional stem washing machines have the following shortcomings: the tobacco stems are soaked in water, resulting in excessive moisture in the tobacco stems, and the moisture in the tobacco stems cannot be accurately controlled after soaking, and it is impossible to clean the debris on the surface of the tobacco stems; the conveyor belt of the traditional stem washing machine cannot achieve all-round cleaning of the material after turning over; the conveyor belt of the traditional stem washing machine has no dust cover, causing water splashing and polluting the surrounding environment.
