Production method of reconstituted tobacco leaves with clean, low consumption and high filling value

Abstract

The invention provides a production method of clean low-consumption high-filling-value reconstructed tobaccos. The production method comprises the following steps: with tobacco stems, broken tobacco flakes and tobacco powder generated in a cigarette product production process as main raw materials, soaking and extracting the tobacco stems, modifying an extracting solution, mixing one part of the modified extracting solution with the tobacco powder and the broken tobacco flakes to prepare tobacco powder pulp, mixing the other part of the modified extracting solution with the residual tobacco stems and beating to prepare tobacco stem fiber pulp, and performing sizing, extruding and suction filtration on the two high-concentration pulp materials to obtain stem fiber-containing tobacco sheets. According to the production method, no liquid is not discharged, so that the zero discharge is realized; tobacco substances are completely remained in the tobacco sheets; no adhesive is added, so that the tobacco sheets completely keep the original fragrance and smell of cigarettes; fibers in the tobacco stems are fully utilized, so that the basic sheet filling value is increased to be not less than 6.0cm<3> / g and finally the physical performance and quality of the tobacco sheets are improved.

Description

technical field [0001] The invention relates to a method for producing reconstituted tobacco leaves, in particular to a method for producing tobacco sheets by using tobacco waste, and belongs to the technical field of tobacco leaf processing. Background technique [0002] During the production and processing of tobacco products such as aging, compounding, leaf stem separation, shredding, drying, cooling, screening, forming and packaging, the following tobacco by-products are inevitably produced: tobacco dust, tobacco stems and fine tobacco particles, etc. For this kind of by-products, most of the existing technologies adopt the method of mixing and forming with the addition of adhesives or pulping and forming according to the papermaking process to reproduce tobacco sheets. The formula needs to reduce the tar release amount of cigarettes and reduce the harm caused by cigarettes to human body. The existing production methods of reconstituted tobacco mainly include: rolling ...

AI Technical Summary

Problems solved by technology

However, the paper-making method tobacco sheet has the following serious defects: 1) Due to the use of paper-making technology for reference, in each link of production, especially the beating and operation links, paper-making technology pays attention to compactness and smoothness, while tobacco sheet emphasizes bulk. There is a certain contradiction, therefore, the closer the process is to the papermaking method, the worse the bulk of the produced flakes; 2) When the papermaking method is used for beating and processing, the sizing concentration can only reach 0.8-1.2%, such a low sizing concentration , when sizing, not only a large amount of sewage containing various substances must be discharged, which brings great pressure to environmental protection, but also consumes extremely high energy consumption. Each ton of sheet production requires 45-75 tons of water, 2500-3000kW of electricity, and steam consumption 10-12 tons, which is not conducive to energy saving, emission reduction, and consumption reduction; 3) The process is complicated, the equipment configuration is various, the investment is large, the land occupation is large, and the production cost and maintenance cost are high

The disadvantages of this method are: (1) The oar concentration is still lower than 1% during papermaking, so water consumption and sewage discharge are unavoidable; (2) The stalk extract needs to be concentrated, which will inevitably lead to problems such as high energy consumption and large equipment investment. ; (3) The concentrate is still coated and backfilled, so it is difficult to backfill due to the current low coating rate in the entire industry

But there are still the following deficiencies: because there is no extraction process and the modification process of the extract, its "plasticity" cannot meet the requirements of the papermaking method; because the tobacco stems are not processed in depth, the mouthfeel and tobacco taste are difficult to meet the requirements of smokers
