Problems solved by technology

Because the tobacco waste has short fibers and high content of miscellaneous cells, low-concentration beating has caused severe cutting and damage of fibers and miscellaneous cells. Poor, low filling value and high energy consumption during beating
However, if high-consistency refining is adopted to make the pulp meet the beating degree required by the paper machine, there are disadvantages such as large equipment investment and high energy consumption.
On the other hand, mixing fine tobacco powder with tobacco stems and tobacco leaves for soaking, extraction, and beating brings problems such as difficulty in material concentration and serious loss of tobacco powder.

Embodiment 1

[0029] (1) Mix 500Kg of washed tobacco stems and 300Kg of shredded tobacco leaves, soak in 4000Kg of water at 20°C for 3 hours, extract, and separate the solid and liquid to obtain a solid-phase mixture and extract; put 200Kg of tobacco powder at a temperature of 600Kg Soak in water at 80°C for 1 hour, extract, and separate solid phase to obtain solid phase tobacco powder and extract;

[0030] (2) Adjust the solid-phase mixture to a concentration of 15%, and transport it to a high-consistency refiner for flaking. After flaking, the beating degree of the material is 10oSR;

[0031] (3) Adjust the mass concentration of the decomposed material to 12%, and transport it to a medium-consistency refiner for beating treatment. During the beating process, adjust the pressure of the grinding zone formed between the grinding plates to 0.3MPa. After the medium-concentration beating treatment, the beating degree of the pulp is 20oSR, which becomes the pulp for the paper machine to make tob...

Embodiment 2

[0037] (1) Mix 400Kg of washed tobacco stems and 300Kg of shredded tobacco leaves, soak in 4900Kg of water at a temperature of 35°C for 1 hour, extract, and separate the solid and liquid to obtain a solid-phase mixture and an extract; Soak in water at 40°C for 3 hours, extract, and separate solid phase to obtain solid phase tobacco powder and extract;

[0038] (2) Adjust the solid-phase mixture to a concentration of 30%, and transport it to a high-consistency refiner for flaking, and the beating degree of the material after flaking is 15oSR;

[0039] (3) Adjust the high-consistency decomposed material to a concentration of 6%, and transport it to a medium-consistency refiner for beating treatment. During the beating process, adjust the pressure of the grinding zone formed between the grinding plates to 0.6MPa. The pulp after medium-concentration beating treatment has a beating degree of 30oSR, which can be used for making tobacco sheets by paper machines;

Abstract

The invention provides a method for preparing tobacco sheets through tobacco waste materials by a papermaking method, which comprises the following steps of: respectively soaking tobacco powder and mixtures of washed tobacco stems and crumbled tobacco leaves into water, carrying out extraction, respectively obtaining solid tobacco stems, tobacco leaf mixtures, solid smoke powder and two kinds of extraction liquid through solid and liquid separation, and combining two kinds of extraction liquid; regulating the tobacco stem and tobacco leaf mixtures obtained through extraction into the materialconcentration being 15 to 30 percent, and then carrying out defibering; regulating the defibered materials into the concentration being 6 to 12 percent and carrying out pulping treatment; diluting the solid smoke powder and the pulped pulp materials to the required concentration after mixing, and making the materials into substrates by a papermaking method after sieving; and concentrating the combined extraction liquid, using the concentrated extraction liquid as coating liquid to be coated on the substrates, and drying and cutting the substrates into tobacco sheet products. The preparation method provided by the invention has the advantages that the damage to material tissue structures in the preparation process is effectively reduced, the physical performance of the tobacco sheets is improved, the yield is high, and the energy consumption is low.

Description

technical field [0001] The invention relates to the production of tobacco sheets in the tobacco industry, in particular to a method for preparing tobacco sheets by papermaking using tobacco material waste. Background technique [0002] Tobacco sheet, also known as reconstituted tobacco leaf, is made of waste (including tobacco stems, tobacco dust and shredded tobacco leaves) produced during the cigarette making process, and processed by different processing methods to prepare thin sheets close to tobacco leaves, which can be reused in the production of cigarettes. The use of tobacco waste to produce tobacco sheets, on the one hand, can maximize the use of tobacco raw materials, reduce the consumption of raw materials in the tobacco industry, thereby reducing costs; Quality of products. Therefore, the development of tobacco sheets has practical significance for the tobacco industry. [0003] The production techniques of tobacco flakes mainly include rolling method, thick p...
