Mixing method of leaf shred, stem shred, expansion shred, thin sheet shred and recycling tobacco shred

Abstract

The invention relates to a mixing method of leaf-silks, cut stems, expansion silks, sheet silks, and recovered cut tobaccos. The method comprises the steps that are the drying, the mixing, the mixture-stirring, and blending of the mixtures; the moisture content of the mixtures are dried until the weight percentage reach 13.5 percent to 20.0 percent; the mixtures are put into cut-tobacco matching storage cabinets for mixing according to the formula demands; multiple mixings of the different mixtures can be realized through the reciprocating turnover among different cut-tobacco matching storage cabinets until the uniformity reach the demands; then finished silks, in which various mixtures are mixed uniformly, are processed through the secondary drying until the moisture content demanded by cigarettes is reached (the moisture content is commonly in the range of 11.5 percent to 14.0 percent); and then the cut-tobacco is flavored, and put into the cut-tobacco matching storage cabinets. The mixing method not only solves the problem of bad uniformity of various mixtures, but also has small influence on the breakage, consumption and filling value of the cut-tobacco because the moisture content of the various mixtures is high, and the pliability and the processing tolerance are good.

Description

technical field [0001] The invention relates to a blending method of shredded tobacco, in particular to a blending method of shredded leaves, shredded stems, expanded shreds, shredded shreds and recycled shredded tobacco. Background technique [0002] At present, in order to improve the refined processing level of the process, many domestic tobacco companies divide the same cigarette formula into multiple formula modules according to the principle of the same or similar quality of tobacco leaves, and then formulate different processing routes for each formula module and impose different personalities. The feed liquid and different process parameters are used to process separately. After the processing is completed, blade blending or leaf shred blending is carried out as required. The shredded leaf is blended by directly drying the shredded leaf to the moisture required for cigarette rolling (generally: 11.5%-14.0%), and then blending the shredded leaf of each module accordi...

AI Technical Summary

Problems solved by technology

The blending frequency of various blends is small and the uniformity is poor, resulting in large fluctuations in cigarette quality; although the multi-stage blending method can greatly improve the uniformity of various blends, due to the various blends Low moisture, cut tobacco is crisp and poor in processing resistance, resulting in large shredded tobacco, high consumption, and decreased filling value

Therefore, in this case, the multi-stage blending method should not be adopted.
