AbstractTo clarify the effect of broken stem screening onthe comprehensive processing qualityof cut stems，this studyused special tobacco stems as samples，andcompared the influences of2 processing techniques （withand without broken stem screening）on the qualityof cut stems，the structureoffinished cut stems，and material consumption.The quality of cut stems was evaluated by a combination of direct measurement and indirect judgment.The structure of cut stems was testedaccording to national standard methods，and thecut stem yield and theconsumption ratioof broken stem screening werecalculated bydry-base material balance and othermethods.The results showedthattheproportion of winnowing rejects for the non-screened batches was 3.76% ，which was 1.32 percentage points higher than that in the screened batch （2.44 % ）， with pricking sensation and stem leakage observed in sensory evaluation.The whole stem ratio of the non-screened batches was 81.40% ，which decreased by 2.72 percentage points compared with the screened batches （84.12% ）. The long stem ratio dropped most significantly by 6.34 percentage points，while the broken stem ratio increased by 1.18 percentage points to 1.85% .The cut stem yield of the non-screened batches was 88.91% ，0.96 percentage points higher than that of the screened batches （87.95% ）. This study provides a reference for optimizing the processing parameters of cut stem production.
