[0002] During the tobacco production process, when workers roll cigarettes, they need to separate the stems in the tobacco to prevent the stems from piercing the cigarettes. When separating the stems, a stem separation device is needed. The existing stem separation device includes a fluidized bed, a stem outlet is provided at the bottom of the fluidized bed, and a tobacco channel is provided at the top. The tobacco channel is connected to a waste channel, and a negative pressure generator is provided in the waste channel. The negative pressure generator is used to suck the tobacco into the waste channel to separate the stems. However, since the negative pressure generator of this separation device is provided on the waste channel, the wind force generated by the negative pressure generator is concentrated on the upper part of the fluidized bed, so that the tobacco at the bottom of the fluidized bed cannot be separated due to insufficient wind force, thereby causing waste of tobacco.
