[Method] The cost and benefit of baking under three different tobacco loading patterns in a bulk curing barn were analyzed from the perspectives of baking equipment cost, labor cost, energy consumption and comprehensive income. The upper, middle and lower tobacco leaves were detected. [Result] Compared with conventional loading pattern, loose-leaf stacking and needle- style tobacco clip loading patterns significantly reduced the labor costs and energy costs during tobacco curing. The comprehensive benefits of tobacco clip and looseleaf stacking loading patterns were higher than that of conventional loading pattern, and the benefits of dry tobacco was improved by 0.67 and 1.07 yuan/kg, respec- tively. The benefit of loose-leaf stacking loading pattern was higher than that of to bacco clip loading pattern, [Conclusion] Among the three loading patterns, the loading pattern of loose-leaf stacking is most worthy of popularization and application.展开更多
