The present invention provides a method for determining the feeding flow rate according to the batch feeding amount. For tobacco leaves continuously produced by super-return loosening and leaf moistening feeding processes, before the super-return loosening process, various data of the current batch of dry cigarette
package materials, historical data of the
moisture content of the cigarette packages before water addition, target outlet
moisture content, historical data of the
water absorption coefficient of the cigarette packages and the total feeding amount are obtained, and the super-return weight and the total material amount at the leaf moistening outlet of this batch are predicted. After the weight proportion of each cigarette
package in this batch is obtained, the feeding amount of each cigarette
package in the leaf moistening feeding section is allocated, and the feeding flow rate is adjusted according to the
material flow data of the flow scale during the production process. After the super-return loosening process, the weight of each cigarette package, the
moisture content of the cigarette package after water addition, and the water addition amount are recorded respectively, and the
water absorption coefficient of each cigarette package is calculated, and the historical
database is updated. Based on the historical data of the cigarette packages before and after super-return loosening and water addition, this method converts the batch feeding index into the flow feeding index, ensures the integrity of the cigarette formula and uniform feeding, and stably improves the intrinsic quality of the cigarette.
