Application of SPC in the Quality Control of the Leaf Tobacco Threshing and Redrying Production
Considering the practical problems in the threshing and redrying production, in order to improve the manufacturing process quality, by using twice hot-air tobacco embellishing as the critical process in production flow and applying SPC technology, through the online data collection, this paper analyzed the causes of quality defects in the course of production and made adjustments. The conclusion is that SPC technology ensures the quality stability of the tobacco processing progress, and also strongly improves the process capability, which achieves the 3σ Control of product quality.
