In the tobacco leaf curing process, along with evaporation and loss of moisture, the tobacco leaf size is decreased, gaps appear, the tobacco leaves move close to each other and eliminate the gaps under the action of the spring pulling and tightening device, the relatively consistent plane tobacco leaf distribution density is kept, circulating hot air evenly penetrates through a tobacco layer, heat is brought in, moisture is brought out, and the tobacco leaves are consistent in yellowing and drying. The tobacco leaf curing time is shortened, and the tobacco leaf curing quality is improved.
