The processing mode of independent vacuum moisture regaining has high processing strength, but the added moisture is limited. The processing mode of first vacuum and then loosening and moisture regaining has lower rate of regaining permeability and poorer uniformity of moisture, and in order to achieve higher rate of regaining permeability, the step of vacuum moisture regaining needs higher processing strength. However, too high processing strength results in deepening of the color of the tobacco leaves and deterioration of the sense of the tobacco leaves.
Therefore, how to provide a moisture regaining process with proper processing strength, which can effectively remove green miscellaneous gases and improve loosening rate and moisture uniformity becomes a technical problem to be solved in the field.
