Tobacco leaf extraction step, is extracted the solable matter in described tobacco leaf by solvent, to obtain tobacco leaf extract;
Feed liquid configuration step, according to described tobacco leaf extract configuration backfill feed liquid;
Refilling step, is backfilled in the stem after described extraction by the described backfill feed liquid configured;
Drying steps, carries out the dry stem after reproducing that obtains to the stem completing backfill.
As an embodiment of the present invention, described tobacco stem shred be through washing stalk, terrier, pressure stalk, chopping and the former stem that formed by the former stalk of tobacco.
As an embodiment of the present invention, in described stem extraction step, described stem carries out secondary continuous countercurrent extraction, and the hybrid extraction that one-level extraction wherein and secondary extraction include solid-liquid material extrudes with solid-liquid the step be separated.
As an embodiment of the present invention, in described stem extraction step, described one-level extraction is spiral continuous extraction, and described mixed material moves in the lump to discharge end from feed end under auger, in moving process, complete extraction.
As an embodiment of the present invention, in described stem extraction step, the extraction of described secondary is hybrid extraction in short-term.
As an embodiment of the present invention, in described stem extraction step, the extraction of described one-level is separated the extract that obtains afterwards through purification and concentrated, and the concentrated water obtained returns extracting system and supplies reextraction used, concentrates the extract obtained and arranges outward.
As an embodiment of the present invention, described stem after the extraction, also comprises pneumatic conveying drying step, and to through extracting and being blown into thermal current in the stem extracted and making it mix, described thermal current takes away the moisture content in described stem, then enters described refilling step.
As an embodiment of the present invention, in described refilling step, the stem being mixed with backfill feed liquid is extruded, in extrusion process, keeps evenly stirring of described stem, to make described tobacco be extruded uniformly, described stem is made fully to absorb described backfill feed liquid.
As an embodiment of the present invention, in described refilling step, extruded the described stem being mixed with backfill feed liquid by screw extruder or two roll press or the trapezoidal continuous extruder of copper gang chain, described stem is undertaken stirring by rotating and implements to extrude by described extruder.
As an embodiment of the present invention, after described drying steps, also comprise loose step, carrying out loose to completing the described stem after pressing steps, making described stem be loose condition (of surface).
Bad to cigarette compatibility characteristic respectively tobacco stem shred and that cigarette compatibility characteristic the is good tobacco leaf of the present invention extracts, extract tobacco stem shred solable matter and the solable matter of tobacco leaf, obtain the tobacco leaf extract containing tobacco leaf solable matter, then tobacco leaf extract is backfilled to described through extraction tobacco stem shred in, make the tobacco stem shred correlation properties being provided with tobacco leaf like this.Because tobacco leaf and stem all belong to tobacco, the solable matter in tobacco leaf can better be absorbed by stem, and after backfill, have the form maintaining stem and the advantage that Filling power is high, tar is low, tobacco component blend proportion is good.If utilize the solable matter of external source to backfill stem, here external source DDGS comprises some spices etc., because they are not stem from tobacco, it is to the bad adaptability of stem, when it backfills stem, can not well be absorbed by stem, therefore the form of its Filling power, tar content, stem all can not well meet the requirements, tobacco component blend proportion is bad.

Detailed description of the invention
Technical scheme of the present invention (ratio, percentage relevant in the present invention, do not specialize, be all considered as mass ratio) is further illustrated below in conjunction with drawings and embodiments.
See Fig. 1, the invention provides a kind of method by tobacco leaf reconstituted tobacco stem, comprising:
Stem extraction step, is extracted the solable matter in described stem by solvent, to obtain the stem after extraction.
Tobacco leaf extraction step, is extracted the solable matter in described tobacco leaf by solvent, to obtain tobacco leaf extract.
Feed liquid configuration step, according to described tobacco leaf extract configuration backfill feed liquid.
Refilling step, is backfilled to the described backfill feed liquid configured in the stem after described extraction.
Drying steps, carries out the dry stem after reproducing that obtains to the stem completing backfill.
As an embodiment of the present invention, described tobacco stem shred be through washing stalk, terrier, pressure stalk, chopping and the former stem that formed by the former stalk of tobacco.
As an embodiment of the present invention, in described stem extraction step, described stem carries out secondary continuous countercurrent extraction, and the hybrid extraction that one-level extraction wherein and secondary extraction include solid-liquid material extrudes with solid-liquid the step be separated.
