After the drying process in HAUNI's HDT pneumatic tobacco dryer, the processed cut tobacco exhibits entanglement and clumping. This issue significantly affects the stability of cut tobacco moisture and temperature, and also poses a hidden risk to product quality control. This paper analyzes this phenomenon and identifies structural differences in the cut tobacco after heating and humidifying as the direct cause. A loosening device was added at the input of the HDT to reorganize the structure of the input cut tobacco. The effectiveness of this device was confirmed through the fluid analysis software Fluent. Further validation through physical experiments showed that the proportion of cut tobacco clumps decreased from 2.14% to 0.42%, confirming that the operation of this device significantly improved the issue of cut tobacco entanglement and clumping.
In order to solve the lean problems such as anti-error ability and low productivity of the new model of mobile tank sugar casing production line of Ningbo Cigarette Factory, lean transformation was carried out to improve the lean problems existing in the sugar casing production line. The results show that through this lean transformation, the errors in the ingredient process of the sugar casing production line have been solved, and productivity has been increased by 50%. This lean process can provide technical support for the lean transformation of other production lines in the industry.
