Technique of pre-expanding treating cabo

Abstract

A tobacco stalk pre-expending processing technics is provided, which is characterized in that: the technics comprises the following procedures: washing, storing, expanding in liquid and marinating with interface the tobacco stalk, expanding the stalk strips, moisture regaining and feeding, storing, pressing sticks and drying for shaping. The technics method of the invention changes the expanding of cut rolled stem into expanding the tobacco stick by using marinating with high temperature and low pressure and then expanding with high temperature and reduced preddure, thus sufficiently eliminating the bad flatus in the tobacco stick as the flatus of the wood or the corrupt straws; the tobacco stick after expanded has increased cells and remarkably enhanced ratio surface, thus the material liquid can filter into the tobacco sticks sufficiently to becoming a natural filling material and adaptation carrier for adjusting the cigarette fragrance and style; the cigarette stick after expanded is large in volume, which, after pressed, is easy being cut into silkiness (similar as the physical behavior of tobacco shred); after dried and shaped normally, the cut rolled stem can crisp naturally, thus increasing the filling capacity. The cut rolled stem processed by the technics method of the invention is basically similar with tobacco shred in color and shape and the alloying evenness of the tobacco shred is increased; besides, the tobacco shred has no bad aftertaste when smoking, but has strong filling capacity and enhanced internal quality.

Description

technical field [0001] The invention relates to a treatment process of tobacco stems in the tobacco industry processing process, in particular to a pre-expansion treatment process of tobacco stems, that is, a process in which tobacco stems are soaked and expanded in related media before being processed. Background technique [0002] Tobacco stem is an integral part of tobacco leaves, its weight accounts for about 25% of tobacco leaves, and its diameter is 3-5mm on average. It is composed of a large amount of lignin and cellulose and a small amount of sugar, nitrogen, nicotine and other substances. Li, Research on the formula of flavoring and adding ingredients to tobacco stems, Shanghai Tobacco Industry, 1995 (4), 18). For example, the total sugar content of cured tobacco stems is only about 1 / 2 of that of leaves, while that of Burley tobacco stems is about 1 / 2. %; the nicotine content of flue-cured tobacco stems is generally about 0.1-0.3%, while the nicotine content of Bur...

AI Technical Summary

Problems solved by technology

Through the on-line inspection of the product line and the inspection of finished cigarettes, it was found that the above tobacco stem treatment process has obvious deficiencies: ① This process cannot effectively remove the bad smoking smell of cut stems

2. The balance relationship between flavoring and feeding ingredients and the adding process and the stem cutting and stem expansion process (Chen Liangyuan et al., experiment on feed point for making cut stems, Tobacco Science and Technology, 2003 (3), 9) makes the existing process very difficult. It is difficult to thoroughly improve the aftertaste after smoking, coordinate the overall aroma of cigarette products, control the burning speed of cigarettes, and then achieve the purpose of reducing tar and harm in the formula of cigarette products; ③ There is no fundamental improvement in shredded tobacco stems The quality cannot guarantee that it is closer to shredded tobacco in physical properties, and its blending uniformity in the finished shredded tobacco will increase the draw resistance of cigarettes (Chen Liangyuan, Cigarette Production Technology, Zhengzhou: Henan Science and Technology Press, 2002) ; ④ The filling value of cut stems did not increase significantly after treatment

The above deficiencies affect the quality of cut stems and restrict the application of tobacco stems in middle and high-end cigarettes
