Loosening and moisture regaining water adding proportion setting method

The invention discloses a loose moisture regaining water adding proportion setting method, which has the main design concept that on the basis of feed-forward prediction, feedback correction and grouping processing, overall design is carried out on the three links, all elements influencing low-temperature moisture regaining outlet moisture are completely represented, accurate setting of the water adding proportion of a loose moisture regaining machine is achieved, and the water adding proportion of the loose moisture regaining machine is accurately set. Introducing a water adding contribution rate coefficient into the theoretical water adding proportion, and completely representing the relationship between the outlet moisture of the loose moisture regaining machine and the water adding proportion; next, the current production is guided by fully utilizing the result of historical batch production, a correction coefficient is formed based on the pre-calibrated water adding deviation of each package of tobacco l
