Embodiment 1

[0032] Such as figure 1 As shown, the present embodiment adopts two rounds of five-stage extraction:

[0033] (1) Take 5 portions of tobacco leaves, 100 grams each;

[0034] (2), the first round of five-level extraction:

[0035] A. Take the first tobacco leaf as raw material, water as solvent, extract at normal temperature with tobacco leaf: water mass ratio of 1:10 solid-liquid ratio, and then separate the solid and liquid by extrusion to obtain the first tobacco residue and For the first extract, the residual moisture is 75-80%;

[0036] B, using the second portion of tobacco leaves as a raw material, mixing the above two portions of extracts as a solvent, extracting at normal temperature, and then separating the solid and liquid by extrusion to obtain a second portion of residue and a second portion of extract;

[0037] C, using the third part of tobacco leaves as raw material, using the third part of the extract as a solvent, extracting at normal temperature, and then ...

Embodiment 2

[0048] Such as figure 2 As shown, the present embodiment adopts two rounds of six-stage extraction:

[0049] (1) Take 6 portions of tobacco leaves, 100 grams each;

[0050] (2), the first round of six-level extraction:

[0051] A. Take the first tobacco leaf as raw material, water as solvent, extract at normal temperature with tobacco leaf: water mass ratio of 1:10 solid-liquid ratio, and then separate the solid and liquid by extrusion to obtain the first tobacco residue and For the first extract, the residual moisture is 75-80%;

[0052] B, using the second portion of tobacco leaves as a raw material, mixing the above two portions of extracts as a solvent, extracting at normal temperature, and then separating the solid and liquid by extrusion to obtain a second portion of residue and a second portion of extract;

[0053] C, using the third part of tobacco leaves as raw material, using the third part of the extract as a solvent, extracting at normal temperature, and then s...

Embodiment 3

[0064] Such as image 3 As shown, the present embodiment adopts two rounds of seven-stage extraction:

[0065] (1), take 7 portions of tobacco leaves, each portion is 100 grams;

[0066] (2), the first round of seven-level extraction:

[0067] A. Take the first tobacco leaf as raw material, water as solvent, extract at normal temperature with tobacco leaf: water mass ratio of 1:10 solid-liquid ratio, and then separate the solid and liquid by extrusion to obtain the first tobacco residue and For the first extract, the residual moisture is 75-80%;

[0068] B, using the second portion of tobacco leaves as a raw material, mixing the above two portions of extracts as a solvent, extracting at normal temperature, and then separating the solid and liquid by extrusion to obtain a second portion of residue and a second portion of extract;

[0069] C, using the third part of tobacco leaves as raw material, using the third part of the extract as a solvent, extracting at normal temperat...

Abstract

The invention relates to a multi-stage extraction and concentration-free reconstituted tobacco preparation method. The method comprises the steps as follows: (1) N parts of tobacco materials are taken, wherein N is larger than or equal to 5 and smaller than or equal to 8; (2) first-round multi-stage extraction is performed, water is used as a solvent, and the solid-liquid ratio of the tobacco materials to the water is 1: 10; (3) first residues and second residues are uniformly mixed, the residues are subjected to pulping and papermaking with conventional methods to form a reconstituted tobacco sheet base, a final extraction solution is not required to be concentrated and is directly used for coating the reconstituted tobacco sheet base, and a first reconstituted tobacco product is obtained. The invention further relates to the reconstituted tobacco obtained with the method. The prepared reconstituted tobacco has the characteristics of clearer aroma, better elegant sense, finer texture and obviously reduced irritation.

Description

technical field [0001] The invention relates to a method for preparing reconstituted tobacco leaves by a papermaking method, in particular to a method for preparing reconstituted tobacco leaves by a papermaking method without concentration, and also relates to a reconstituted tobacco leaf obtained by the method, which belongs to the field of tobacco. Background technique [0002] At present, the conventional production process of reconstituted tobacco leaves by papermaking method includes extraction, solid-liquid separation, concentration, pulping, sheet making, coating, and drying. The general temperature of the concentration process is 65-70°C. This process will cause the loss of aroma components in reconstituted tobacco leaves and affect the quality of reconstituted tobacco leaves produced by papermaking. Contents of the invention [0003] In order to solve the above technical problems, the present invention mainly provides a method for preparing reconstituted tobacco l...
