A kind of production method of tobacco sheet cigarette paper

Abstract

The invention relates to a production method of tobacco sheet cigarette paper. The method comprises the following steps of: (1) adding tobacco leaf pieces or tobacco stems into hot water, and extracting at 40-70 DEG C for 20-40 minutes, wherein the adding amount of the hot water is 3-5 times of the weight of the tobacco pieces; (2) primarily extruding the extracted tobacco leaf pieces or tobacco stems with a pulp extrusion machine, then adding hot water of which the amount is 1-3 times of the total weight of the tobacco leaf pieces or tobacco stems, extracting at 45+ / -5 DEG C for 20 minutes, extruding again, and then pulping with a pulping machine until the SR (Schopper-Riegler) degree reaches 25-40; (3) pulping applied fibers with the pulping machine until the SR degree reaches 40-75, mixing with the tobacco pulp, and making cigarette paper, wherein the adding amount of the applied fibers is 0.25-0.5 time of the total weight of the tobacco leaf pieces or tobacco stems; and (4) mixingthe two extraction liquids, then concentrating until the relative density reaches 1.02-1.2 g / cm<3>, adding potassium salts, food pigments and spices, mixing to obtain a coating liquid, and spreading the coating liquid on the cigarette paper. The method provided by the invention can improve the cigarette quality, can reduce the woody smoke of cigarettes and reduce the irritation, and makes naturalsweet taste of tobaccos more predominant.

Description

technical field [0001] The invention belongs to the technical field of cigarette materials, and in particular relates to a production method of tobacco sheet cigarette paper capable of improving the smoking taste of cigarettes. Background technique [0002] The production of cigarette paper has a history of nearly 70 years in China, but only in the past ten years, my country's paper industry has introduced and absorbed foreign advanced equipment and technology to meet the needs of consumers and produce cigarettes that are in line with the world's advanced level. , Substituting imported cigarette paper, the physical indicators and performance of cigarette paper have made a qualitative leap. However, in the prior art, ordinary cigarette paper only plays the role of wrapping shredded tobacco and providing visual effects. Usually, in order to meet the normal operation of high-speed cigarette machines, the production of cigarette paper focuses on physical properties. All commerci...

Problems solved by technology

As we all know, the so-called smoking is actually the smoke produced after the shredded tobacco is burned, and the cigarette paper is the carrier of the shredded tobacco. The difference between cigarette paper and other cigarette materials is that it will participate in the burning of cigarettes. Cigarette paper produced from commercial pulp boards has the problem of producing more woody gas and pungent sensation during the burning process of cigarettes, which affects the pure smell of cigarette smoke

[0003] "Cigarette Paper with High Air Permeability" disclosed in Chinese patent CN1324586A is completely made of different commercial pulp boards through beating and papermaking processes, and has excellent longitudinal tensile strength, whiteness and air permeability; Chinese patent CN101195981A discloses "A Cigarette Paper and Its Preparation Method" uses a gradient increase in the air permeability of the cigarette from the shredded tobacco end to the filter tip within a certain range to improve the quality of smoking; these preparation processes have common deficiencies, Both improve the smoking quality of cigarettes only by improving the physical properties of cigarette paper

"A Functional Cigarette Paper and Its Preparation Method" disclosed in Chinese patent CN101215802A is to grind functional plants into powder and add them to the slurry to make cigarette paper to improve the taste and comfort of smoking. The method has the defect that the functional plants have not been soaked and extracted, and their active ingredients are lost in the process of mixing with the slurry, etc.

So far, there has been no method for preparing cigarette paper using tobacco as a raw material through beating and papermaking processes.
