A kind of preparation method of shredded stem for thin cigarette

Abstract

The invention discloses a making method of cut tobaccos for thin cigarettes and aims at providing a thin cigarette cut-tobacco making method capable of remarkably improving the quality stability of the thin cigarettes. The making method comprises the following steps of tobacco preparation, screening, tobacco washing, tobacco storage, humidity increase, tobacco pressing, tobacco cutting, cut tobacco adding, cut tobacco drying and cut tobacco perfuming. By adopting the making method, the tobacco moistening efficiency is improved, the lignin content is reduced, the sensory quality of the cut tobaccos is improved, the cut tobacco yield is increased, the quality stability of the thin cigarettes is improved, and the production cost and production consumption are reduced.

Description

technical field [0001] The invention relates to the technical field of shredded tobacco technology, in particular to a method for preparing shredded tobacco stems. Background technique [0002] Slim cigarettes usually refer to cigarette samples with a circumference of (17±0.1) mm. Compared with conventional cigarettes, they have the characteristics of small cigarette circumference, low tar content, and long cigarettes. It has become an international development trend at present. And more and more accepted by the market. However, due to the small diameter of thin cigarettes, the shredded tobacco is easy to curl into agglomerates, and the mixing uniformity is low, which leads to low product quality stability, low effective operation rate of crimping and wrapping, large process loss, and cigarette draw resistance, tar and sensory quality. Large fluctuations, narrow use of raw materials and other issues. In the process, it is often necessary to reduce the cutting width to impr...

Problems solved by technology

[0004] Chinese patent CN101444328B discloses a cut stem processing technology, which mainly includes heating and humidifying tobacco stems, cutting stems, increasing temperature of cut stems, expanding cut stems, cutting stems, and storing cabinets; For shredded stems, there are many stalks in the process of cutting stems, the process is broken, and the swelling effect of stem pieces is poor, the filling value and silk yield are low, and the quality stability of shredded stems cannot be effectively guaranteed

[0005] Chinese patent CN101711600B discloses a biochemical treatment process for cut stems, including stem washing, deep stem washing, surface dehydration of tobacco stems, stem drying, shredded stem cutting, enzyme treatment, and large-scale feeding. Although this treatment process can effectively reduce the content of lignin and protein that are not conducive to odor absorption, there are many stem heads and strip stems, poor filament uniformity, low filling value, many processes, complicated procedures and long time-consuming

[0006] Chinese patent CN101708070B discloses a 2 o 2 and ammonia water to reduce the content of cell wall substances. After treatment by this method, the content of cell wall substances is reduced by 42.3%, and the ratio of sugar to alkali and the total amount of aroma components are increased; Warm baking, and the use of ammonia water is likely to cause secondary pollution and lead to the smell of smoke, which is not suitable for industrial production in the workshop

[0007] Chinese patent CN102599640B discloses a method of directly compressing the tobacco stem after threshing, changing its tissue structure, and then using compressed air to spray an enzyme preparation to store the stem, so as to reduce the content of pectin and cellulose and improve the quality of the stem slices; The tobacco stems behind the leaves have low water content and poor processing resistance, and the fiber structure is easily torn and broken during the stem pressing process, resulting in large fragments and low filamentation rate during the stem cutting process; at the same time, the thickness of the pressed stems and cut stems Large, with a high proportion of flakes, and a high proportion of flowering smoke when blended and applied

[0008] Chinese patent CN103284315B provides a production process of reconstituted cut stems in which tobacco extract is added in the flavoring process of cut stems. It adds lactic acid and glycerin aqueous solution containing biological enzyme preparations during the storage of stems, which effectively improves the quality of cut stems for smoking. ; but the production process is still relatively high due to the large gap between the pressed stalks

[0009] Chinese patent CN103704867B discloses a process for graded treatment of tobacco stems using circulating protease aqueous solution and compound enzyme liquid, which mainly includes cleaning and degradation of tobacco stems, moisture regain and storage of tobacco stems, expansion and compression of tobacco stems, degradation and storage of stem pieces, and Slice feeding, stalk drying, dry stalk storage, dry stalk expansion and pressing, stalk cutting and feeding, stalk expansion and drying, etc.; this treatment process improves the degradation of biological macromolecules such as cellulose and pectin As a result, the sensory quality of cut stems has been improved, but the process is complicated and the processing intensity is too high, including three times of high-temperature steam steaming, two times of high-temperature and high-humidity expansion, and two times of direct pressing of stems, resulting in low silk yield and high cost

However, there have been no reports on the research on the processing technology of cut stems for slim tobacco, and the traditional cut stem processing technology cannot meet the physical and chemical quality requirements of cut tobacco for slim cigarettes.
