Technical field
The present invention relates to Nicotiana tabacum L. manufactures field, specifically a kind of preparation facilitiess of tobacco material concentrated solution and method.
Background technology
Domestic papermaking-method reconstituted tobaccos are typically with two-step method and produce, and are first fully soaked Nicotiana tabacum L. active ingredient using solvent
Bubble out, then be backfilling on Nicotiana tabacum L. substrate after tobacco extract is concentrated, its produce critical process include extracting, concentrate, manufacture paper with pulp,
The processes such as coating.The macromole such as a certain amount of protein, pectic substance, cellulose, hemicellulose are usually contained in tobacco extract
Material, these compositions in extracting solution, only separate these and admittedly hang thing guarantee product typically presented in admittedly hanging thing
Quality.Chinese patent ZL200910063930.0《The comprehensive impurity new technology of tobacco sheet material extract and impurity removed system》
Middle employing flocculation-supercentrifugal process processes tobacco extraction liquid, effectively increases papermaking-method reconstituted tobaccos product quality.Papermaking at present
In method reconstituted tobacco industry, concentrator is typically to use for reference the multiple-effect vacuum concentration systems that pharmacy and food service industry use, due to
The complexity of Nicotiana tabacum L. composition, concentration process haves such problems as that efficiency is low, heat top tank structure and easily ties trowel used for plastering, as too low in thickening temperature, dense
The contracting time can be oversize, affects thickening efficiency；But if temperature is too high, partly lower boiling aroma component can volatilize, and thus makes
The waste having become this perfume (or spice) of Nicotiana tabacum L. is lost, the final organoleptic quality affecting reconstituted tobacco.
The at present typically widely used two-step method processing technique of production of tobacco sheets by paper making method, by Nicotiana tabacum L. leftover bits and pieces, mainly
Including cabo, cigarette be broken, offal, soak in water or organic solvent so as in solable matter separates with fibrous matter, extract
Rear offal, cabo, after making beating process, slurry are delivered to shaping of manufacturing paper with pulp on paper machine, then will be processed after solable matter
It is sprayed on thin slice so as to keep original smoke, form reconstituted tobacoo through a series of drying.
At present in tobacco sheets by paper making method production technology, the method for concentration of extracting solution is mainly using being by vacuum distillation
Method concentrates to solution.Method (vacuum distillation) problem big due to not only existing energy consumption of evaporation, operating cost is higher,
The energy-saving and emission-reduction policy of the increasingly stringent being proposed with country is not corresponded yet, further, since temperature higher (65 DEG C) in evaporation process,
Effective ingredient (as fragrance matter) in feed liquid is likely to rotten or is evaporated, thus affecting the quality of final Nicotiana tabacum L..
Patent《A kind of tobacco extract method for concentration》(application number：201310457044.2) disclose a kind of raising Nicotiana tabacum L.
The method of extracting solution thickening efficiency, mainly or using common heating in vacuum concentration technology.Patent《A kind of tobacco extract
Concentration method》(application number：201210325062.0) disclose one kind using reverse osmosis technology, tobacco extract is carried out
The technique concentrating, but there is reverse osmosis membrane price and maintenance cost is higher, concentration speed is unstable.Patent《One kind is made
The method of paper method reconstituted tobacco refined liquid freeze concentration》(application number：201510543292.8) disclose a kind of paper-making method reconstructed
The method of Nicotiana tabacum L. refined liquid freeze concentration, but have such problems as continuously to run, efficiency of energy utilization relatively low.
