To investigate the effects of offline materials in different production processes and the sequence of production batches on the yield of cut stem, four types of offline materials： screened broken stems from the stem washing process, residual stems in the cutting machine, rejected stem tips from the cutting process, and rejected stem heads from the winnowing process along with the production batch sequence were selected as experimental factors. Descriptive statistics were conducted to analyze the correlation between these factors and cut stem yield. Using a controlled variable approach, the impact of offline indicators from each production process on cut stem yield was measured and discussed.The results showed that the production batch sequence had the highest coefficient of variation (56.42%). Cut stem yield exhibited a negative correlation with screened broken stems, rejected stem tips, residual stems in the cutting machine, and rejected stem heads, while showing a positive correlation with the production batch sequence. As the quantities of screened broken stems, residual stems in the cutting machine, rejected stem tips, and rejected stem heads increased, the cut stem yield consistently decreased. Across production batches, silk yield was lowest in the first batch, peaked in the fifth batch, and stabilized in intermediate batches. Meanwhile, the amounts of screened broken stems, residual stems, and rejected stem tips decreased to varying degrees and stabilized over successive batches, whereas the rejected stem heads showed a gradual but insignificant increase.These findings indicate that optimizing the stem blend, reducing cutting machine residue, minimizing rejected stem tips, and controlling the rejection rate of stem heads can enhance yield of cut stem. Additionally, regulating the offline material quantities across different production batches and refining relevant process parameters can improve raw material utilization efficiency, thereby achieving higher cut stem yield.
