Cut stems for cigarettes and preparation method thereof as well as cigarettes

Abstract

The invention relates to the technical field of tobacco processing and in particular relates to cut stems for cigarettes and a preparation method thereof as well as the cigarettes. The preparation method comprises: carrying out size screening, microwave expansion, stem washing, pressure stem wetting, ultrafine stem pressing, stem cutting, cut stem feeding and cut stem storage on tobacco stem material to obtain a cut stem crude product; taking the cut stem crude product and carrying out cut stem drying; winnowing, adding aroma into the cut stems and storing the cut stems to obtain the cut stems for the cigarettes. According to the preparation method provided by the invention, a previous stem size is pre-treated; meanwhile, expanded stems with a specific specification are obtained through utilizing a microwave technology; then the cut stem crude product is obtained through adopting an ultrafine stem pressing and primary shredding technology; finally, the filiform cut stems are obtained through utilizing a pipe plate drying technology. An experiment result shows that compared with the cut stems prepared by a traditional method, the cut stems for the cigarettes, prepared by the method, have the advantages that the sensory quality is greatly improved, the color and luster are improved, the aroma quantity is more sufficient, odor and irritation are alleviated, the aftertaste is more comfortable, and the ratio of doping the cut stems into cut tobaccos is improved.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a shredded tobacco stem, a preparation method thereof and a cigarette. Background technique [0002] Tobacco stems are an important component of tobacco leaves, and after separation of stem leaves, tobacco stems accounting for about 25% of the total weight of tobacco leaves can be obtained. The types of chemical components contained in tobacco stems are basically the same as those in tobacco leaves. Shredded stems are used as the filling material of cigarettes, which can reduce the tar content of cigarettes. [0003] In the prior art, there are many methods for producing shredded stems, most of which go through steps such as washing the stems, storing the stems, moistening the stems, feeding, increasing temperature and humidity, pressing the stems, cutting the stems, expanding, and adding flavor. The key in these steps is expansion, that is, to make the shrunken cut ...

AI Technical Summary

Problems solved by technology

[0005] Tobacco stem processing in cigarette factories adopts more technological processes, such as rehydrating the tobacco stem, storing the stem, cutting the stem, feeding the stem, expanding the stem, and adding flavor, that is, the processing technology of "cutting first and then expanding". Tobacco stems of different sizes are processed at the same time, and the same process and parameters are used to rehydrate the tobacco stems. The uniformity of moisture resurfacing is poor and the energy consumption is high. The difference is large, and most of them are sheet cut stems; the shape of sheet cut stems is quite different from that of cigarette leaves, resulting in poor blending uniformity of the two, and large fluctuations in weight and draw resistance of cigarettes after rolling , the quality stability of cigarettes is poor; at the same time, due to the high expansion rate, light color, and large difference in shape from shredded tobacco, the flaky shredded stems are easy to be distinguished in cigarettes and affect consumers' feelings; removal, affects the smoking taste of cigarettes, and also hinders the increase in the proportion of shredded stems used in cigarettes
