The unique craftsmanship of 黄鹤楼•论道 (Huanghelou - Lunda) can be described simply as "stir-frying in a small pot, cooking by classification." During its production, a 300kg/h experimental production line is utilized, featuring various conditions for grouped processing, including continuous grouping for adding materials, first and second cycle feeding, and different methods for drying tobacco leaves. Multiple patented technologies have been applied for this process. —— Patent technology for the dual entrance and exit of the storage cabinet —— Utility model patent technology for the closed-loop control of hot air circulation in the feeding machine —— Utility model patent technology for the multi-nozzle feeding system in the feeding machine —— Invention patent technology for the three-tobacco blending system in the mixing process

黄鹤楼•论道在工艺上的特色用通俗的话来说就是“小锅炒菜、分类烹制”。 在其生产过程中所运用的300kg/h试验制丝线，同时具备连续分组加料、一二次循环加料、不同烟丝干燥方式等分组加工的各种条件，已申请了多项专利技术。 ——贮柜的双进双出发明专利技术 ——加料机的热风循环闭环控制实用新型专利技术 ——加料机的多喷头加料系统实用新型专利技术 ——混丝拒的三丝掺兑发明专利技术
