Flexible threshing and pneumatic separating process

Abstract

The invention discloses a flexible threshing and pneumatic separating process. The flexible threshing and pneumatic separating process comprises the working procedures of feeding, leaf base threshing, leaf body threshing, primary pneumatic separating, secondary threshing, secondary pneumatic separating, tertiary threshing, tertiary pneumatic separating, quaternary threshing and quaternary pneumatic separating, wherein a dozen leaf base threshing mode is adopted for the leaf base threshing, a dozen leaf body threshing mode is adopted for the leaf body threshing, the working procedure of feeding is preferably feeding for the working procedure of leaf base threshing or leaf body threshing and can also be direct pneumatic separating leaf apex feeding for the working procedure of pneumatic separating, and the working procedures of primary pneumatic separating, secondary threshing, secondary pneumatic separating, tertiary threshing, tertiary pneumatic separating, quaternary threshing and quaternary pneumatic separating are performed in sequence. By means of the flexible threshing and pneumatic separating process, slit leaves can be threshed and pneumatically separated in a targeted mode, production organization can be also simplified, device investment can be reduced, a process route is flexible, and devices are simple.

Description

technical field [0001] The invention belongs to the technical field of tobacco leaf processing, and in particular relates to a flexible leaf threshing and air separation process. Background technique [0002] In order to separate the leaves and stems in the tobacco leaves, leaf threshing and redrying enterprises (workshops) use threshing air separation equipment. The traditional threshing and air separation process is aimed at threshing whole leaves. With the fine processing requirements of tobacco leaves, tobacco leaves often need to be cut before threshing. For the slit leaves, there are currently three threshing and air separation processes: one is mixed threshing, that is, the cut leaves are mixed together on one threshing air separation line for threshing and air separation. The fragments have different physical properties and characteristics, and the quality of the leaves after threshing is poor; the second is to change the threshing, that is, the cut leaves are sepa...

Problems solved by technology

For the slit leaves, there are currently three threshing and air separation processes: one is mixed threshing, that is, the cut leaves are mixed together on one threshing air separation line for threshing and air separation. The fragments have different physical properties and characteristics, and the quality of the leaves after threshing is poor; the second is to change the threshing, that is, the cut leaves are separately threshed on a threshing line, and the leaves are temporarily divided according to different materials. Replace the nails and frames of the leaf thresher to perform targeted leaf beating. The disadvantage of this process is that it is time-consuming and laborious, and continuous production cannot be realized; Fragment leaf threshing air separation requirements, the disadvantage of this process is that the equipment investment is large and the equipment utilization rate is low
