Problems solved by technology

[0005] There is still little research on the wetting ability of the coating liquid on the substrate, but it is not difficult to find out from the actual production that the type and content of the substance in the coating liquid are important factors affecting its wetting ability
In addition to the type of raw materials, the refining and concentration process of the extract, important factors that lead to changes in the type and content of substances in the coating solut

Example Embodiment

[0050] The invention provides a preparation method of paper-making reconstituted tobacco leaf and a method for improving the absorption of coating liquid of a paper-making reconstituted tobacco leaf base sheet. Liquid absorbency. figure 1 It is shown as a process flow chart of the papermaking method reconstituted tobacco leaf of the present invention, as shown in the figure, the preparation method of the papermaking method reconstituted tobacco leaf comprises the following steps:

[0051] 1) After the tobacco raw material is extracted with an extractant, solid-liquid separation is performed to obtain tobacco insoluble matter and tobacco extract.

[0052] Specifically, the tobacco raw materials are tobacco stems, tobacco flakes and tobacco powder, and the three raw materials are mixed according to the mass ratio of (4-8):(1-4):(1-4), and then the total weight of the raw materials is added. 4 to 7 times of water, soak and extract at 40 to 80° C. for 30 to 60 minutes, and then s...

Abstract

The invention provides a paper-making reconstituted tobacco preparation method and a method for improving coating liquid absorbability of a paper-making reconstituted tobacco substrate. The paper-making reconstituted tobacco preparation method includes steps: 1) after extracting with an extracting agent, performing solid-liquid separation to obtain tobacco insoluble matters and tobacco extract liquid; 2) subjecting the tobacco insoluble matters to pulping, and performing net forming and pressing to obtain a wet substrate; 3) subjecting the wet substrate to drying, coating of bicarbonate and drying to obtain a substrate; 4) subjecting the tobacco extract liquid to refining concentration to obtain coating liquid; or adding organic acid after refining concentration to obtain the coating liquid; 5) coating the substrate with the coating liquid, and drying and slitting to obtain reconstituted tobacco. Liquid absorbability of the substrate is improved by thermal decomposition action of bicarbonate; preferably, coating liquid absorbability of the paper-making reconstituted tobacco substrate is improved by improving substrate infiltration performance of the coating liquid through reductionof residue content of the coating liquid.

Description

technical field [0001] The invention relates to the technical field of papermaking reconstituted tobacco leaves, in particular to a method for preparing papermaking reconstituted tobacco leaves and a method for improving the absorbability of a papermaking reconstituted tobacco leaf base sheet to a coating solution. Background technique [0002] Reconstituted tobacco leaf, also known as tobacco flakes, is an important form of tobacco waste reuse and has great environmental and economic value. Its production technologies mainly include rolling method, thick pulp method, and papermaking method. The typical production process of reconstituted tobacco leaves by papermaking method is to extract tobacco raw materials with extractant and separate solid and liquid to obtain tobacco extract and tobacco insoluble matter. The tobacco extract is refined, concentrated, flavored and added to make coating liquid. Tobacco The insoluble matter is made into a tobacco base sheet by pulping and ...
