Abstract
The invention discloses a method for producing paper-making reconstituted tobacco. The method comprises the following steps of extracting essential oil from a tobacco raw material through supercritical carbon dioxide fluid; obtaining the tobacco raw material which is subjected to extraction; transferring the tobacco raw material which is subjected to the extraction to a raw material extraction tank; mixing the tobacco raw material which is subjected to the extraction with tobacco stems; performing water extraction to obtain extract liquid and solid residue; concentrating the extract liquid and then adding the essential oil into the concentrated extract to obtain dip-coating liquid; preparing a film base from the solid residue by a paper-making process; and finally coating the dip-coating liquid onto the film base to obtain the reconstituted tobacco. The method is technically feasible and can be widely used for producing the paper-making reconstituted tobacco, and the product quality is easily controlled. By the method, the use ratio of the tobacco raw material can be improved, the burden of sewage discharge can be reduced, and the appearance and sensory quality of the paper-making reconstituted tobacco can be improved.
Description
Technical field:
The present invention relates to a kind of manufacture method of papermaking-method reconstituted tobaccos, particularly utilize flavor component and the humectation composition of the selective raw tobacco material of supercritical fluid, to reduce the loss of this constituents in the papermaking-method reconstituted tobaccos production process, improve the method for papermaking-method reconstituted tobaccos organoleptic quality and humid keeping performance.
Background technology:
Papermaking-method reconstituted tobaccos has anti-good processability, falls the characteristics such as burnt effect is remarkable, product quality plasticity is strong, is widely used at tobacco business.The raw material of papermaking-method reconstituted tobaccos extracts soluble component wherein through the water extraction at present, and extract is used for the lotion of reconstituted tobacco through concentrated after the purified treatment.But this technology also exists certain defective, poor in slurrying and the loss in the process of manufacturing paper with pulp, wastewater treatment pressure organoleptic quality large, reconstituted tobacco such as the water-insoluble component in the tobacco, this has caused the utilization rate of raw material low, the raw tobacco material resource nervous, the product usage ratio is low.
Summary of the invention:
For overcoming the defective of prior art, the object of the present invention is to provide a kind of technical feasibility, product quality controllability strong, and can be widely used in the Manufacturing Method of Products that papermaking-method reconstituted tobaccos is produced.This technology is intended to improve the utilization rate of raw tobacco material, outward appearance and the aesthetic quality who reduces sewage discharge pressure, improves papermaking-method reconstituted tobaccos.
Technical solution problem of the present invention adopts following technical scheme:
