The manufacturing process of modern cigarette products generally goes through seven major processes: initial baking of tobacco leaves, threshing and re-baking, fermentation of tobacco leaves, cigarette formula, cigarette shredding, cigarette rolling, and cigarette packaging. Only the production process can be transferred to consumers as commodities. Every mellow and rich cigarette embodies the hard work and sweat of thousands of tobacco people, and is permeated with the connotation of constantly developing new technologies and corporate culture. First curing of tobacco leaves This is the first step in turning the grown tobacco leaves into raw materials for cigarettes. It is a process in which farmers place the fresh tobacco leaves collected from the fields in a curing house to bake and modulate them, turning them into "raw tobacco", the raw material for cigarettes. Tobacco farmers often say: "Tobacco planting is the foundation, and baking is the key." Tobacco leaf curing is a process in which the temperature, humidity and ventilation conditions are controlled in the curing room to dehydrate and dry the tobacco leaves into tobacco leaf products with certain quality, style and grade standards. The curing process is a physiological and biochemical transformation process of the inherent quality of tobacco leaves. Fresh tobacco only has potential quality before it is dried. Curing can present its potential quality characteristics into clear and specific characteristics and fix them. Only through baking can the harvest quantity of fresh tobacco be turned into a realistic yield of raw tobacco. After curing, the tobacco leaves have undergone significant changes in their content, appearance and fine structure. From the appearance, the color of the tobacco leaves changes from yellow-green to yellow; the moisture content of the tobacco leaves changes from an expanded state of 80 to 90% to withering, drying, and even charring. These two changes reflect the biochemical changes of the transformation, decomposition and certain condensation of organic matter in tobacco leaves. It is a chemical enzymatic reaction process and a physical process of water loss. These changes are the only way for fresh cigarettes to transform into original cigarettes and reveal their unique aroma and ideal color. Threshed and re-cured flue-cured cigarettes currently produced in my country, as the main raw material, first-cured tobacco leaves cannot be directly supplied to cigarette factories. They must undergo re-curing processing, that is, a second moisture adjustment of the tobacco leaves is carried out on the basis of the first-cured tobacco to make it Become the real raw material for cigarette production. The first-cured tobacco leaves need to be re-cured before being converted into raw materials for cigarette industry production. This is because the moisture content of the first-cured tobacco leaves is very inconsistent due to uneven moisture regain during grading and bundling. In addition, the climate and storage conditions vary from place to place. Those with high moisture content are prone to mildew and deterioration. The functions of re-baking tobacco leaves are: first, to adjust the moisture content and prevent mildew; second, to eliminate impurities and purify the aroma; third, to kill insects and sterilize, which is beneficial to storage; and fourth, to maintain color, which is beneficial to production. After reheating and drying the recured tobacco leaves, the physical and chemical properties are further optimized, the quality of the tobacco leaves is improved, and the hygroscopicity is weakened, which is conducive to the natural aging of the tobacco leaves during the storage process. Thinning and re-curing is a tobacco leaf re-curing technology that has been continuously promoted and applied since the 1950s and 1960s. As the name suggests, the raw tobacco is separated from the tobacco stems through leaf beating equipment before being re-cured. The tobacco leaves and tobacco stems are re-roasted separately, and then packaged and stored separately. This threshing and re-baking process of separately treating the leaves and stems has many advantages compared to the traditional hanging rod re-baking (re-baking the entire tobacco, and then separating the leaves and stems during cigarette production): it reduces tobacco leaf fragmentation; It facilitates the transportation of tobacco leaves; it can provide high-quality and standardized raw materials to cigarette factories; and it is also beneficial to the long-term storage and alcoholization of raw materials. Tobacco leaf fermentation Tobacco leaves that have not been stored and aged for more than one year after re-curing are collectively called new tobacco. There are varying degrees of defects in the quality of new cigarettes, such as heavy green odor, strong irritation, impurity, rough and uncomfortable smoke, and failure to reveal the fragrance. Especially low-grade new tobacco leaves also have shortcomings such as bitterness, pungency, and astringency. Therefore, new tobacco should not be used directly to make cigarettes. It must undergo natural alcoholization or artificial fermentation before rolling, so that the color of the tobacco leaves becomes darker, the cyan color is reduced, the impurities are eliminated, the aroma appears, the stimulation is weakened, and the aftertaste is reflected. This is the role of fermentation of tobacco leaves. Tobacco leaf fermentation is divided into two methods: natural fermentation and artificial fermentation: The natural fermentation method stores the re-cured tobacco leaves in a warehouse. With the influence of changes in natural climate conditions, the intrinsic quality of the tobacco leaves is transformed. This natural fermentation method is also called natural alcoholization, or alcoholization or aging, and is the mildest fermentation method. The raw materials used by many domestic manufacturers generally use tobacco leaves that have been naturally fermented for 2 to 3 years. The artificial fermentation method is to place new tobacco in a temperature and humidity controlled fermentation chamber to accelerate the aging process of tobacco leaves, so as to achieve the effect of improving the quality of raw materials in a short time. Although artificially fermented tobacco leaves are inferior to naturally fermented tobacco leaves in terms of color, aroma and pungency, the quality of newer cigarettes is still significantly improved. Cigarette manufacturers widely use this fermentation method because of its short fermentation cycle, small inventory occupation and fast capital turnover.

Cigarette Recipe Just as a chef must prepare the main ingredients and accessories of a delicacy before cooking, the production of cigarette products also requires the pursuit of a harmonious unity of color, aroma, taste and safety. The cigarette formula is a reasonable combination of various types, grades and styles of tobacco leaf raw materials and flavors, fragrances and other auxiliary materials to produce the best quality effect. The leaf group formula is the prerequisite for forming the style characteristics of cigarette products. Tobacco, as an agricultural product, is affected by its genetic genes, cultivation techniques, soil conditions, climatic factors, etc., so tobacco leaves from different regions, different varieties, and even different parts of the same plant have great differences in quality and style. For example, some tobacco leaves have sufficient smoke, but the miscellaneous gas is heavy and irritating; some tobacco leaves have moderate strength, but not enough aroma. Through the leaf group formula, we use the different characteristics of various tobacco leaves to strive for the best combination, so that the various tobacco leaves participating in the formula can make use of their strengths and avoid their weaknesses, complement each other, and play their respective roles in a coordinated manner. Flavoring is the "flavoring" technology in cigarette formula. Through the leaf group formula, the grade and quality of cigarettes are basically guaranteed, but there will still be some impure smell, which needs to be improved by adding flavorings. Cigarette flavors are harmless to the human body. The formula is complex and is designed and prepared by professionals to make a solution ready to be sprayed into tobacco. Once the cigarette formula is determined, its quality style is finalized, and its quality remains relatively stable during long-term production. Cigarette consumers who smoke a certain brand of cigarettes for a long time will develop a soft spot for it. Therefore, cigarette manufacturers are doing everything possible to strengthen quality assurance and continue to make fine adjustments to cigarette formulas according to market changes and raw material conditions to better meet consumer needs. To make modern cigarettes that are plump, beautiful, and good-smoking, tobacco leaves must first be made into shredded tobacco. The cigarette silk making process is the main processing technology for cigarette production. It is a process in which tobacco leaves are made into qualified shredded tobacco according to the physical and chemical properties of the tobacco leaf raw materials and through a variety of processing steps according to certain procedures. In the cigarette production process, the filament making process has the longest process, the most complicated procedures, and the most types of equipment. The main technological purposes of cigarette shredded technology: First, the quality of shredded tobacco used for rolling is stable and consistent, ensuring uniform raw material ratio, uniform application of flavor materials, appropriate width of shredded tobacco, and uniform moisture content. Second, the cut tobacco produced has a high filling value, increases toughness, and saves raw materials. The third is to reduce fragmentation and loss as much as possible. The silk-making process is divided into three relatively independent processes and combinations: blade making, stem silk making, and leaf silk making. Including: tobacco leaf moisture regain, proportioning, leaf moistening, leaf storage, shredding, drying; stem moistening, stem pressing, stem expansion, stem cutting, stem drying; tobacco thin slice moistening and shredding processes. Then the shredded leaves, shredded stems and shredded flakes are evenly mixed and blended, and then sprayed with flavors and fragrances after cooling. The role of tobacco flavoring: adjust the pH value of the smoke produced by burning tobacco, weaken the irritation of the smoke, make the aftertaste clean, and tend to be mellow and pure; make the aroma of cigarettes more exposed and increase; adjust the quality of the tobacco and stems Combustion performance; inhibit mold and prevent mildew. After the tobacco is added, it is stored for a certain period of time to fully absorb the flavors and fragrances before entering the cigarette rolling process. Cigarette rolling Cigarette rolling refers to the process of using special cigarette rolling and splicing equipment to manufacture cigarette raw and auxiliary materials into filtered cigarettes or filter-free cigarettes. The entire process of cigarette rolling is divided into two parts: rolling and joining. The rolling part consists of four systems including cut tobacco feeding, stencil paper supply, rolling forming and cigarette cutting; the tipping part consists of three systems including cigarette supply, filter tip supply and tipping paper supply. In the rolling production workshop of a cigarette factory, there are many rolling and splicing units that can complete the rolling production tasks of cigarettes of the same or different brands and specifications at the same time. Since the advent of the first cigarette making machine in the world, after more than a century of continuous improvement, the production efficiency and production capacity of cigarette making machines have gradually improved. At present, cigarette manufacturers in my country generally use internationally advanced rolling and splicing units, with a production capacity of 8,000 to 16,000 cigarettes/minute. Modern high-tech cigarette equipment not only improves labor productivity at ultra-high speeds, but also effectively reduces raw material costs with high technology and ensures the quality of cigarette products. The new generation of cigarette machines generally adopts microcomputer monitoring and operating systems, which can facilitate machine operation and human-machine dialogue. It has functions such as fault display, instantaneous accumulation of production data, and recording of operating information; it is equipped with a cigarette weight inspection system to detect leaking cigarettes. There is an automatic elimination function for cigarettes, empty cigarettes, oil stained cigarettes, dirty cigarettes, damaged cigarettes, etc. Among numerous mechanical and electrical equipment, cigarette equipment is a typical complex mechanical and electrical integration product.

The specifications of cigarettes are usually expressed as "length × circumference". Cigarette packaging: Rolled cigarettes must be packaged before they can become cigarette products on the market. The functions of cigarette packaging: First, it is convenient for consumers to identify and enjoy. Cigarettes with good intrinsic quality can be recognized and liked by consumers through beautiful and elegant packaging, thereby establishing a brand image. The fact that cigarettes have become a means of social communication also depends on their beautiful appearance; the outer packaging of cigarettes is also an indicator of their product grade and specifications. The second is to protect product quality. The packaging of cigarettes can preserve the moisture of the cigarette within a certain period of time, prevent mildew in the humid season, and prevent loosening in the dry season; it can also keep the essence from graying and maintain the aroma value. The third is to facilitate transportation, warehousing and sales for the commercial sector. The cigarette packaging process includes: small box packaging → cigarette packaging → box packaging. Small box packaging is divided into soft packaging and hard box packaging. The outer layer wrapped with soft paper is called soft packaging; the outer layer wrapped with white cardboard is called hard box packaging. Whether it is soft box packaging or hard box packaging, it includes lining paper packaging, trademark paper packaging, transparent paper packaging and other process links. Cigarette carton packaging is divided into soft carton packaging and hard carton packaging. Soft strip packaging is usually called "strip packaging", and hard strip packaging is called "strip box". The two ends of the "strip package" need to be pasted with horizontal label paper. The outside of the "box" is wrapped with a layer of transparent paper. Boxing: Generally, corrugated cartons are used for packaging. Tinned cigarettes packed in tinplate iron boxes are generally packed in wooden boxes. my country's cigarette packaging equipment continues to develop in the direction of mechanization, automation and continuity. The production capacity has increased from 100 packages/minute in the 1950s to the current level of 500-700 packages/minute. The output has increased significantly and the quality has been significantly improved, meeting the increasingly diverse market needs.
