Problems solved by technology

Because tobacco waste such as tobacco stems and tobacco powder has short fibers and high content of non-fibrous components, low-concentration beating causes serious cutting and damage of fibers and non-fibrous components. High content, large material loss, low copying yield, poor sheet strength, low filling value, and high energy consumption in the beating process
However, if high-concentration refining is adopted to make the pulp meet the beating degree required by the paper machine, there will be problems such as excessive separation, brooming, and crushing of materials and fibers during the refining process, and there will be large investment in equipment. Disadvantages such as high energy consumption

Abstract

The invention belongs to the technical field of tobacco sheet manufacturing, and discloses a method for processing materials for manufacturing tobacco sheets with tobacco waste and the tobacco sheets manufactured with the method. The method includes the steps that after a mixture of tobacco stems and tobacco powder is extracted, the concentration is gradually lowered under the medium concentration condition; multistage soft defibrination processing is carried out; smashing and defibrination are carried out on materials obtained through defibrination processing and outer-fiber long-fiber stuff; and obtained slurry is evenly mixed to obtain materials used for manufacturing tobacco sheet base sheets. According to the method, gradual, sufficient and even mixing and defibering are carried out on the solid-phase mixture of the tobacco stems and the tobacco powder in the multistage soft defibrination processing process; moderate thin fibrillation is generated; the cutting effect and the damage effect on the materials in the defibrination process are reduced; the high thin fibrillation degree of the outer-fiber long-fiber stuff is obtained under the high pulping strength; the adsorption effect and the cross linking effect on thin components in the materials are facilitated; the retention rate of the tobacco powder and packing on a net is improved; the yield is improved; and the porosity and the physical performance of the tobacco sheet are improved.

Description

technical field [0001] The invention belongs to the technical field of tobacco sheet preparation, and in particular relates to a method for processing materials for preparing tobacco sheet by using tobacco waste and the tobacco sheet. Background technique [0002] Tobacco sheet by papermaking method uses waste such as tobacco stems, tobacco leaf fragments and tobacco dust produced in the cigarette production process as raw materials, and uses wet papermaking method to prepare thin sheets close to tobacco leaves, which can be used in cigarette production. Paper-making tobacco flakes have low density, high filling value, good flexibility and processing resistance, high silk forming rate, good combustion performance, low tar release, and strong plasticity of the product, which has become one of the important ways for the comprehensive utilization of tobacco raw material waste . On the other hand, using tobacco waste to prepare paper-making tobacco sheets can make full use of t...
