Abstract

Traditional bulk curing barns face limitations such as immobility, difficulty adapting to shifting tobacco-growing regions and disaster prevention needs, and low curing efficiency. To address these issues, this study developed and optimized a tent type mobile tobacco curing barn and its associated curing process. Six tent-type mobile barns with different materials, specifications, and energy sources were compared regarding installation cost, thermal insulation performance, energy consumption, and curing effectiveness. The results indicated that the No. 2 biomass barn, constructed with polyurethane material and U-shaped edging, was selected as the optimal structure. This barn exhibited excellent thermal insulation, with a temperature drop of only 1.2°C after 2 hours from an initial temperature of 48.0°C. It also demonstrated low unit energy consumption (3.07 CNY/kg) and convenient installation. Furthermore, the heights of the air inlet and return air outlet were optimized to 400 mm and 380 mm, respectively, effectively improving the uniformity of temperature and humidity within the barn. Regarding the curing process, by refining the temperature and humidity control nodes and extending the yellowing and color-fixing stages, Curing Process 1 (Treatment Group 1) performed remarkably: the proportion of high-grade cured tobacco leaves significantly increased, the total content of aroma substances increased by 37.29%, and the protein content decreased by 5.46%.Compared to the traditional bulk curing barn, the tent-type mobile barn reduced curing costs by 18.75%, increased the proportion of high-grade tobacco by 87.50%, reduced the rate of green and mixed defective leaves by 26.67%, and also improved sensory quality. These results demonstrate that the tent-type mobile tobacco curing barn and its optimized associated curing process offer significant advantages in energy saving, cost reduction, and enhancing tobacco quality, making it suitable for promotion and application in tobacco-growing areas. effectively improving the uniformity of temperature and humidity within the barn.
