Processing technology reducing large leaf rate of leaves

Abstract

The invention provides a processing technology reducing the large leaf rate of leaves. The processing technology comprises the following steps: feeding pretreated tobacco leaves into a leaf-threshingair separating machine set, carrying out vibrating screening on leaves on at least previous one air separating outlet vibrating groove for primary leaf-threshing and on at most previous two air separating outlet vibrating grooves for secondary leaf-threshing, and feeding the leaves after vibrating screening into a large-leaf threshing machine for second-time leaf threshing; and mixing the leaves after the second-time leaf threshing and tobacco materials of the batch, and further carrying out the follow-up fabrication processing. According to the processing technology, the leaves on the at least previous one air separating outlet vibrating groove for primary leaf-threshing and on the at most previous two air separating outlet vibrating grooves for secondary leaf-threshing of the leaf-threshing air separating operation are subjected to vibrating screening, the leaves after vibrating screening are fed into the large-leaf threshing machine for second-time leaf threshing, the large leaves are selectively screened for re-threshing treatment, therefore, 80% or above of the large leaves are treated with pertinence, the content of the large leaves is reduced, meanwhile, re-treatment is notcarried out on original medium-size and small leaves, so that the increment of the broken leaf rate is controlled, and the purposes of reducing the large leaf rate, increasing the medium-size leaf rate and reducing the broken leaf rate of tobacco leaves is effectively achieved.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, [0002] In particular, the present invention relates to a processing technique for reducing the large slice rate of blades. Background technique [0003] Through the study of the influence of the structure distribution of shredded tobacco in finished cigarettes on the weight of cigarettes and the stability of draw resistance, reducing the filament rate, increasing the rate of medium filaments, and reducing the rate of broken shreds are beneficial to the weight of finished cigarettes, especially slim cigarettes, and the stability of draw resistance . Traditional threshing and rebaking enterprises will try to reduce the intensity of leaf treatment in order to pursue the rate of large and medium slices of leaves, and increase the rate of large and medium slices of finished tobacco. According to the quality requirements of finished cigarette shredded tobacco, in order to achieve the tob...

Problems solved by technology

[0004] Changing the shape of the leaf thresher frame can achieve the purpose of reducing the rate of large flakes, but there is still room for further optimization to reduce the rate of large flakes, and the tobacco leaves are repeatedly thrashed in the leaf thresher, and the fragmentation rate is easy to increase; although increasing the threshing intensity can be improved to a certain extent To achieve the purpose of reducing the rate of large slices, but at the same time it will increase the workload of the leaf thresher, increase power consumption, and increase the fragmentation rate; the method of re-threshing leaves after threshing leaves is to reduce the large slices while reducing the original small and medium The leaves were also threshed again, which increased the debris rate and reduced the treatment efficiency of the tobacco leaves; the method of sieving the threshed tobacco leaves and threshing the large leaves separately, due to the large flow of tobacco leaves, the screening effect of large pieces It will be slightly worse, and the screening process will easily cause an increase in the fragmentation rate
