Problems solved by technology

[0005] The above-mentioned reconstituted tobacco leaves are all compared with natural tobacco leaves when making shreds. Aiming at the difficulties in regaining moisture and making shreds, most of the research is currently done from the perspective of shredded equipment to improve the parameters of the rewetting process. Starting to improve the out-of-synchronization of the moisture absorption rate of reconstituted tobacco leaves and sheet tobacco is another main research direction in this field.

Embodiment 1

[0040] Weigh 1kg of 400 mesh kaolin, place it in a roasting furnace at 650°C for 3 hours, and after cooling, add 2kg of an alkaline solution with a concentration of 15% (potassium hydroxide: sodium hydroxide: potassium carbonate = 1:1: 0.2 (mass ratio), pH=10.4), reacted at 80°C for 4.5 hours, washed to pH=6.9 after the reaction, and dried at 115°C for 18 hours to obtain modified kaolin. Put the modified kaolin in a reaction kettle, add 10% of its mass raw konjac starch, mix well, add water and stir to obtain a mixed paste with a concentration of 45%, and react at 65°C for 1 hour. Then dry at 115° C. for 12 hours, and granulate to obtain a moisture-absorbing and moisturizing filler of 200 to 400 meshes.

[0041] The obtained filler is reconstituted tobacco leaf production process according to the existing papermaking method, and the moisture-absorbing and moisturizing filler is used as one of the fillers in the wet end papermaking, and the base sheet papermaking is carried out...

Embodiment 2

[0043] Weigh 1kg of 400 mesh kaolin, place it in a roasting furnace at 750°C for 5 hours, and after cooling, add 3kg of a 20% alkaline solution (potassium hydroxide: sodium hydroxide: potassium carbonate=2:1: 0.5 (mass ratio) pH=11.2), reacted at 85°C for 6 hours, washed at pH=7.4 after the reaction, and dried at 115°C for 18 hours to obtain modified kaolin. Put the modified kaolin in the reaction kettle, add 5% raw konjac starch, mix well, add water and stir to obtain a mixed paste with a concentration of 60%, and react at 50°C for 2.5 hours. Then dry at 115° C. for 12 hours, and granulate to obtain a moisture-absorbing and moisturizing filler of 200 to 400 meshes.

[0044] According to the existing paper-making method reconstituted tobacco leaf production process, the moisture-absorbing and moisturizing filler is used as one of the fillers in the wet-end papermaking process, and the base sheet papermaking is carried out according to the dry weight of the slurry at an amount of...

Embodiment 3

[0046] Weigh 1 kg of 400-600 mesh kaolin, place it in a roasting furnace at 850 ° C for 8 hours, and add 1.8 kg of alkaline solution with a concentration of 25% (potassium hydroxide: sodium hydroxide: potassium carbonate = 1 :2:0.7 (mass ratio) pH=12.1), react at 90°C for 9 hours, wash at pH=7.4 after the reaction, and dry at 115°C for 18 hours to obtain modified kaolin. Put the modified kaolin in the reaction kettle, add 1% konjac raw starch, mix thoroughly, add water and stir to obtain a mixed paste with a concentration of 58%, and react at 75°C for 0.5 hours. Then dry at 115°C for 12 hours and granulate to obtain a moisture-absorbing and moisturizing filler with a mesh size of 200-400.

Abstract

The invention discloses a preparation method for moisture absorbing and keeping type packing and the application of the packing in the production of reconstituted tobaccos by using a paper-making method. According to the invention, kaolin is subjected to high-temperature calcining and alkaline solution treatment so as to obtain modified kaolin; and then, the modified kaolin is wrapped with starch so as to obtain the moisture absorbing and keeping type packing, wherein the moisture absorbing and keeping type packing is of a porous structure with a large specific surface area and a high porosity, and the surface of the packing has hydrophilic groups. The moisture absorbing and keeping type packing as packing for the production of reconstituted tobaccos by using an existing paper-making method is used for wetly manufacturing paper with pulp and / or coating. According to the invention, through the scientifically treated and appropriately applied packing, the moisture absorbing and keeping performance of reconstituted tobaccos is improved, and the gap between the moisture absorbing and keeping performances of reconstituted tobaccos and natural tobaccos is narrowed; and problems of crushing and piece deviating and the like generally existing in the cut tobacco manufacturing of reconstituted tobaccos by using a paper-making method are solved.

Description

technical field [0001] The invention relates to the field of papermaking tobacco sheet production technology, and more specifically, to a method for preparing a moisture-absorbing and moisturizing filler and its application in the production of reconstituted tobacco leaves by papermaking. Background technique [0002] Reconstituted tobacco leaves are processed by using tobacco stems, tobacco dust, tobacco sheets and tobacco leaves with low availability as raw materials. It can be mixed with natural tobacco leaves and processed into cigarettes. Reconstituted tobacco leaves can increase the burning degree of cigarettes, reduce harmful components in cigarettes, reduce tobacco tar and nicotine content, and improve the internal quality of cigarette products. [0003] Since the 1950s, people have started a lot of research on reconstituted tobacco, and the production and processing technology and equipment of reconstituted tobacco have been developed rapidly. With the development ...
