Uniform feeding control method for redrying production

Abstract

The invention discloses a uniform feeding control method for redrying production. The method comprises the following steps of dividing a plurality of groups according to a formula ratio and a nicotine value in a feeding and mixing stage, measuring and calculating the feeding ratio of each group, and obtaining a feeding round based on the single-batch feeding amount corresponding to a minimum-batch feeding unit and the total feeding amount; meanwhile, based on the feeding ratio of each group and the total feeding amount, acquiring a single-group total feeding amount, predicting the feeding amount required by each group of tobacco leaves in each feeding process by using the single-batch feeding amount, the feeding ratio of each group and the total feeding amount of each group in combination with a recursion thought and a greedy algorithm, and finally, fusing the feeding amount prediction results of all groups of all feeding rounds; and obtaining a target feeding and assembling scheme. According to the method, the labor cost is effectively reduced, the method is more scientific, meanwhile, overall feeding and single batch of raw materials are ensured to be uniform, and therefore the feeding uniformity is improved, re-drying homogenization processing control is enhanced, and the quality stability of re-dried finished tobacco strips can be remarkably improved.

Description

technical field [0001] The invention relates to the field of tobacco processing, in particular to a uniform feeding control method for redrying production. Background technique [0002] With the gradual formation of the development pattern of large groups and big brands in the tobacco industry and the increasing competition at home and abroad, cigarette companies are paying more and more attention to the quality homogeneity of cigarette products. Therefore, homogenization processing is one of the main directions of tobacco processing enterprises at present, and the target requirements for rebaking and homogenization processing are also proposed in this field: to control the coefficient of variation of nicotine in finished tobacco sheets within 5%. At the same time, the new version of the tobacco industry standard YC / T366-2010 also clearly puts forward the indicators and methods for evaluating the quality uniformity of flue-cured tobacco. With the introduction of the standard...

Problems solved by technology

[0006] In view of this, the present invention aims to provide a uniform feeding control method for rebaking production, which solves the problem of unscientific grouping and manual feeding in the rebaking feeding process For problems with high complexity, it not only reduces labor costs, but also is more scientific. At the same time, it ensures the uniformity of the overall feeding and single batch of raw materials, effectively avoiding the situation that a certain material is finished in advance when multiple material groups are fed, thereby improving The uniformity of feeding is improved, and the control of the homogeneous processing of re-baking is strengthened, and finally the quality stability of the finished re-baking tobacco is effectively improved.
