Problems solved by technology

[0005] The main disadvantages of the wet papermaking method are: a large amount of water is required as a transport medium in the substrate papermaking process, serious loss of tobacco aroma, serious wastewater pollution, and low production efficiency; the dry papermaking method has strict requirements for the pre-treatment of raw materials, and is currently in the In the development stage, the processing and production of raw materials, the design and selection of papermaking equipment, the coating methods of adhesives and extracts, etc., are all in the process of experimentation and exploration
The published patents of reconstituted tobacco leaves by dry papermaking method include: Chinese invention patent "A dry papermaking method reconstituted tobacco leaf and its production method" (application number: 200810030146.5 application date: 2008.08.08), Japan Tobacco Industry Co., Ltd. filed in China The invention patent "Tobacco Sheet and Its Manufacturing Method and Manufacturing System" (application number: 00808488.2, filing date: 2000.06.02), neither of these two schemes involves the preparation method of dry slag fiber suitable for dry molding equipment content

Embodiment 1

[0019] 1. Weigh the tobacco powder, broken stalks, and debris raw materials according to the weight ratio of 1:2:1, then send them into a sealed reaction kettle, soak them in 75% ethanol for 5 minutes, and then continue to stir for 40 minutes. Minutes, during the stirring process, the temperature of the feed liquid remains at 60 degrees, and the stirring speed is 15 rpm;

[0020] 2. Take out the liquid in the reactor and release the slag;

[0021] 3. Send the slag to the horizontal sedimentation separator, further separate the residual extract in the slag, and then discharge the slag to ensure that the dryness of the discharged slag is ≥ 70%;

[0022] 4. Transport the slag to the dispersing and screening machine for dispersing, crushing and screening. The qualified slag will enter the next process, and the unqualified slag will be sent to the crusher for crushing before secondary screening. The final qualified slag enters the next process, and the screen mesh is 80-100 mesh. ...

Embodiment 2

[0025] 1. Weigh the tobacco powder, broken stalks, and debris raw materials according to the weight ratio of 2:1:2, then put them into a sealed reaction kettle, soak them in 75% ethanol for 5 minutes, and then stir continuously for 30 minutes. Minutes, during the stirring process, the temperature of the feed liquid is maintained at 50 degrees, and the stirring speed is 10 rpm;

[0026] 2. Take out the liquid in the reactor and release the slag;

[0027] Subsequent procedures are the same as 3-5 of Embodiment 1.

[0028] Since the extract prepared by the alcohol extraction method can retain the original components of the tobacco to the greatest extent, the slag after the alcohol extraction has a high bulkiness after drying, and the base sheet made on the dry papermaking reconstituted tobacco leaf production equipment is loose. The thickness is high, so it is beneficial to increase the coating rate of the substrate and increase the filling value of the reconstituted tobacco lea...

Abstract

The invention provides a raw material preparation method of dry method reconstituted tobacco. An ethanol extraction method is adopted, lipid utmost fragrant substances in tobacco residuals such as tobacco powder, broken stalks and fragments are extracted out through a reverse alcohol extraction method and are used for preparing extracta, then, solid-liquid separation is carried out on slag charge, residual ethanol is extracted, remaining moisture is discharged out, and then the slag charge is screened and scattered, and dry method reconstituted tobacco raw materials are manufactured after being dried by a rotary drum dryer. Not only can intrinsic frangrance of natural tobacco be reserved to the maximum degree, but also the pollution of waste water to environment is reduced. The raw material preparation method of the dry method reconstituted tobacco is especially beneficial to accurate measuring of dry method paper-making process reconstituted tobacco equipment to raw materials in the process of manufacturing paper with pulp, and conducive to improving the filling value of the reconstituted tobacco.

Description

technical field [0001] The invention relates to a raw material preparation method of dry-process reconstituted tobacco leaves, specifically a method for preparing waste and inferior raw materials in tobacco leaves as substrate raw materials for a dry-process reconstituted tobacco leaf production line after alcohol extraction, and belongs to the technical field of raw material preparation in the cigarette industry. Background technique [0002] During the cigarette processing process, there are tobacco residues such as tobacco powder, shredded stems, and chips, which account for 5% to 7% of the total production. Sheet or shredded regenerated tobacco products made of technically processed and recombined tobacco substances as the main raw materials. As the filling material of cigarette products, reconstituted tobacco leaf is an important part of cigarette formula. On the one hand, it can be used instead of tobacco leaf, save tobacco leaf raw materials, effectively reduce th...
