The traditional thick slurry method for reproducing tobacco leaves is to grind tobacco raw materials into fine powder, uniformly disperse the fine powder in water, add adhesives and other additives, uniformly stir the fine powder, spread the fine powder on the surface of a metal sheet evenly, mold and dry the fine powder, and peel the fine powder off the metal sheet after the moisture reaches the index to obtain the tobacco sheets meeting the requirements. The prepared slices enter a tobacco rolling group after being cut into slices, and finally the conventional cigarettes in the market are formed through the process links such as cut tobacco making and the like. However, as the filling value of the conventional thick-pulp reconstituted tobacco is lower, the conventional thick-pulp reconstituted tobacco is easy to crush and has poor processing resistance in the production process, and is gradually replaced by the paper-making reconstituted tobacco, only a few tobacco enterprises still use the conventional thick-pulp reconstituted tobacco at present.

The prior thick paste method heating non-combustion thin sheet is to stir tobacco particles ground into fine powder, glycerol, propylene glycol, adhesive, plant fibers and the like in water to form thick paste, then spread the thick paste on the surface of a metal thin plate flatly for molding and drying, and peel the thick paste from the metal thin plate after the moisture reaches the index to obtain the sheet with the heating non-combustion thick paste method meeting the requirements. The sheet is rolled into a large roll, then the large roll is rewound and divided into small rolls according to design indexes, and the corresponding small rolls are cut into shreds, sticks, cuts, composites and other process links to finally form the conventional ordered heating nonflammable cigarettes in the market. Or directly forming the conventional disordered heating nonflammable cigarettes in the market through the process links of slicing, shredding, blending, forming rods, cutting, compounding and the like.

The terms "comprising," "including," "having," "containing," or any other variation thereof, as used herein, are intended to cover a non-exclusive inclusion. For example, a composition, step, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition, step, method, article, or apparatus.

The conjunction "consisting of … …" excludes any unspecified element, step or component. If used in a claim, such phrase will cause the claim to be closed, such that it does not include materials other than those described, except for conventional impurities associated therewith. When the phrase "consisting of … …" appears in a clause of the claim body, rather than immediately following the subject, it is limited to only the elements described in that clause; other elements are not excluded from the stated claims as a whole.

When an equivalent, concentration, or other value or parameter is expressed as a range, preferred range, or a range bounded by a list of upper preferable values and lower preferable values, this is to be understood as specifically disclosing all ranges formed from any pair of any upper range limit or preferred value and any lower range limit or preferred value, regardless of whether ranges are separately disclosed. For example, when ranges of "1 to 5" are disclosed, the described ranges should be construed to include ranges of "1 to 4", "1 to 3", "1 to 2 and 4 to 5", "1 to 3 and 5", and the like.
