Description

Technical Field

[0001] The utility model relates to the technical field of tobacco processing and screening, in particular to a drum screening machine for tobacco processing. Background Art

[0002] Tobacco can be made into cigarettes, dry tobacco, pipe tobacco, cigars, etc. for people to smoke. The fragments below 3mm in the tobacco processing process are high-quality raw materials, but there are also some larger leaves in the tobacco processing process, which usually require a drum screening machine.

[0003] The drum screening machine screens tobacco and separates large leaves from fragments. However, during processing, the large leaves must be poured out after screening in the screening drum and then the tobacco must be reloaded, which is inefficient. At the same time, the leaves are easily stuck in the gaps of the filter screen, reducing the screening efficiency. For this reason, we propose a drum screening machine for tobacco processing.
