Method for preparing tobacco pulp from regenerated tobacco

Abstract

The invention discloses a method for preparing tobacco pulp from regenerated tobacco. The method includes the following steps that 1, the tobacco raw material is extracted and then subjected to solid-liquid separation, and an aqueous solvent is added into tobacco filter residues obtained after solid-liquid separation, wherein the aqueous solvent contains salt and alkali and a nonionic surfactant; 2, the tobacco filter residues are fed into a pulping machine for defibering; 3, a complex enzyme preparation is added into the filter residues obtained after defibering for enzymolysis; 4, after enzymolysis is completed, pulping continues till the needed pulping degree is obtained, and the tobacco pulp is obtained. In the method for preparing the tobacco pulp, the pulp forming characteristic of the tobacco is effectively improved by organically combining the physical action, the enzyme preparation and the chemical reagent according to the specificity of the tobacco raw material, so that the effects of improving the papermaking property of the tobacco pulp and increasing the physical indexes of the regenerated tobacco are achieved, and meanwhile the interior quality of the regenerated tobacco is improved.

Description

technical field [0001] The invention relates to the field of regenerated tobacco leaves, in particular to a method for preparing tobacco pulp of regenerated tobacco leaves by a papermaking method. Background technique [0002] Reconstituted tobacco is a regenerated product made from tobacco dust and tobacco stems as the main raw materials, and is shredded and used as artificial tobacco leaves for cigarettes. The production methods of reconstituted tobacco mainly include rolling method, thick pulp method and papermaking method. Due to the advantages of high filling value, good combustion performance, low tar release, and recombinable chemical components, reconstituted tobacco leaves by papermaking method have been more and more widely used in the tobacco industry. The method is as follows: first extract raw materials such as tobacco stems, tobacco powder, and shredded tobacco leaves through clear water at a certain temperature, and then separate the soluble extract from the ...

AI Technical Summary

Problems solved by technology

[0005] 1. Poor papermaking performance and running stability of the paper machine;

[0006] 2. During the papermaking process, the slurry is retained, the water filtration performance is poor, and it is difficult to increase the amount of filler added;

[0007] 3. The bulkiness and poor liquid absorption performance of the paper limit the amount of flavors and fragrances that are crucial to regenerated tobacco leaves, which in turn affects their intrinsic quality;

[0008] 4. The low paper strength cannot meet the requirements of papermaking. It is necessary to add plant fibers to improve its physical strength and ensure the smooth operation of the paper machine. However, the addition of external fibers will inevitably have a certain negative impact on its internal quality. For example, using Cigarette products become more woody, irritating, and taste worse

[0009] 5. The uniformity of paper formation is poor, which seriously affects the coating uniformity of the coating liquid
