In order to solve the problems of high leaf content and waste of tobacco leaves during the process of reroasting.Under the condition of ensuring proper moisture and temperature of the tobacco leaves in the moistening process,this experiment studied the re-lationship between the efficiency of tobacco leaves on the belt after first-stage beating,second-stage beating,and third-stage beating,and the speed of the leaf beater and the frequency of the air separator.Then the influence of the percentage of leaf in the belt stem on the frequency of the fan and the opening of the damper was studied.By comparing the test data at all levels,the best speed of Chen-zhou Guiyang(Yun 87)C3F(DBBFA processing module)for blade beating was 663,557,520 r·min-1,the back stem beating was 762 r·min-1,and the back stem fan frequency was 43 Hz.The results showed that compared with the control group,the percentage of leaf in the stem of the module decreased from 0.85%to 0.67%,decreased by 0.18%and decreased by 21.18%,and the effect was significant.In conclusion,the technology can reduce the leaf content to a lower level,improve the yield of tobacco leaves,and have greater economic benefits.
