Method for slitting, striking and redrying tobacco

Abstract

The invention relates to a method for slitting, striking and redrying tobacco, which is technically characterized by comprising the following step of: cutting tobacco lead bases with minimum tensile strength, poorest physical processing resistance and poorer perception smoke panel test quality and appearance quality in the tobacco for singly cutting, striking and redrying. The method has the main advantages that remained non leaf base tobacco leaves are crushed to be smaller when leaves and stems are separated singly after the tobacco leaf bases are cut for being singly processed, the leaf structures are more uniform after the leaves are separated from the stems, the green and impurity content in the tobacco is reduced, thus the large-medium leaf ratio after the striking is improved, the crushing generated when the leaves are separated from the stems is reduced, the leaf yield is improved, and the purity of the tobacco is increased. After the tobacco is processed by using a slitting, striking and redrying method of the invention, the leaf base smoking quality is better, the fragrance quantity is improved, the smoke explosive force is increased, the smoking comfort is enhanced, and the impurity gases are reduced, thus the use value of the tobacco can be improved.

Description

technical field [0001] The invention relates to a tobacco leaf cutting and re-baking method, which is a new method of finely cutting different parts of each tobacco leaf and then performing threshing and re-baking. The technical feature is that each tobacco leaf has different parts / regions Features: Finely cut off the leaf base part of the tobacco leaf which has the smallest tensile strength, the worst physical processing resistance, poor sensory evaluation, smoking quality and appearance quality, and the leaf base part of the tobacco leaf is cut separately, threshed and re-roasted. It belongs to the technical field of tobacco leaf threshing and redrying production technology and processing. Background technique [0002] In order to adapt to the development of Chinese-style cigarettes, cigarette industrial enterprises put forward higher requirements for leaf threshing and redrying. At present, threshing and redrying has become a weak link in the research of characteristic t...

Problems solved by technology

[0024] 4. Problems existing in the original whole-leaf threshing and redrying technology: the traditional whole-leaf threshing and redrying process does not take into account the differences in physical properties, chemical indicators, sensory evaluation and smoking quality, and appearance quality of tobacco leaves at different locations in the tobacco leaves. Adopting the traditional threshing and re-roasting process has the following disadvantages at the same time:

[0025] First, for different locations of tobacco leaves, the intrinsic quality and physical processing resistance of the leaf-base and non-leaf-base tobacco leaves are different. The traditional method of threshing and re-baking does not adopt targeted processes according to the quality differences of different locations of tobacco leaves. The processing method has no obvious effect on improving the overall quality of the blade and the production rate

[0026] Second, according to the current development needs of Chinese cigarette brands, the traditional whole-leaf threshing method affects the subsequent shredding and wrapping process and cannot be targeted for grouping and processing of different tobacco leaf qualities, which is not beneficial to cigarettes. The improvement of raw material quality has restricted the further development of Chinese cigarette brands

[0027] Third, the traditional way of threshing and redrying tobacco leaves limits the maximization of the use value of tobacco leaves, cannot maintain and exert the raw material characteristics and advantages of high-quality tobacco leaves to the greatest extent, and cannot reflect its own value to the greatest extent

[0028] Fourth, the threshing unit used for the whole leaf threshing and re-baking of traditional tobacco leaves uses four threshing times, and no reasonable threshing technology is adopted according to the physical processing resistance of the tobacco leaves, resulting in large fragments and flakes during the threshing process. The reduction of the rate and the rate of large and medium slices, resulting in a decrease in the profit of the leaf threshing and re-baking enterprises

[0029] Fifth, adopting the traditional redrying mode is not conducive to the improvement of the internal quality of tobacco leaves, the removal of harmful substances in tobacco leaves, and the realization of the process of "flavor preservation, aroma enhancement, and aroma creation" of tobacco leaves. It can no longer meet the needs of the development of Chinese-style cigarettes

[0030] Sixth, the traditional whole-leaf threshing and redrying production process mode is only to stabilize the aging moisture of tobacco leaves and reduce the risk of mildew in tobacco leaves during the natural aging process, while ignoring the requirements for the quality and efficiency of aging tobacco leaves

[0035] 2. Differences in chemical characteristics of different parts / regions of tobacco leaves: the test results of total polyphenol content, carotenoids, nicotine, and reducing sugar content in tobacco show: non-leaf base > whole leaf > leaf base

[0036] 3. Differences in sensory quality between different parts / regions of tobacco leaves and the whole tobacco leaf: 3.1 Whole leaf: enough aroma, good aroma penetration, slightly less thick, but layered, slightly turbid aroma, smoke concentration Still enough, slightly miscellaneous, the taste is still comfortable, slightly irritating
