A kind of composite papermaking method reconstituted tobacco and production method thereof
Technical field
The present invention relates to a kind of tobacco product and preparation technology thereof, particularly utilize to be directly used in rudimentary or waste/hypo-tobacco leaf and the tobacco stalk raw material that cigarette products is produced, adopt the reconstituted tobacco and the production method thereof of composite papermaking manufactured.
Background technology
Papermaking-method reconstituted tobaccos is to adopt the paper process principle, and utilization can not be directly used in the low grade or the abandoned tobacco raw material of cigarette products, through extraction, slurrying, substrate manufacture paper with pulp, be coated with, dry, cut, technology such as perfuming and making.Papermaking-method reconstituted tobaccos is with its high added value, high fill-ratio and specifically functional aspect the reducing tar and reducing harm thereof, accepted by the World tobacco production industry as the main flow trend of reconstituted tobacco and adopts.Through the development of nearly decades, the production technology of papermaking-method reconstituted tobaccos is gradually improved, but because technology is intrinsic, not good to the fat-soluble ingredient processing method in the tobacco, make original fragrance of tobacco and the loss of suction flavor serious.Because in the present papermaking-method reconstituted tobaccos production technology all is that solvent carries out raw material abstraction with water, be difficult to extract fat-soluble ingredient in the tobacco comprehensively, and in slurry defibrination process, fat-soluble ingredient can penetrate in the slurry plain boiled water because of cell membrane is broken, not only be difficult to collect, and often big, the high increase of slurry viscosity, the dehydration difficulty of causing of viscosity because of its molecular weight, and when manufacturing paper with pulp, stop up easily the network of rivers and woollen blanket (so-called " pitch trouble "), final result not only causes the loss of this perfume of tobacco serious, and has seriously hindered the raising of production efficiency.This essential defect never finds comparatively desirable solution.
In order fully to keep the tobacco fat-soluble ingredient, improve the quality of papermaking-method reconstituted tobaccos, the someone proposes the scheme of adding tobacco powder or add tobacco powder behind approach flow in slurry, but since inconsiderate complete, to such an extent as to be difficult to be applied to actual production.For the scheme of adding tobacco powder in the slurry, guarantee that tobacco powder and slurry are fused well, tobacco powder is fully run through, otherwise tobacco powder can swim in network of rivers portion slurry bed of material surface, and will fully run through, must be long time of contact with moisture, and DDGS very easily dissolves in the tobacco powder, fat-soluble ingredient is also separated out easily, thereby causes the loss of the effective ingredient in the tobacco powder to increase, and has lost due effect and does not reach desirable effect.For the scheme of behind approach flow, adding tobacco powder, tobacco powder directly is added in the top layer of substrate, though shortened action time with water, but because substrate surface has tobacco powder, with woollen blanket and drying cylinder contact process in, very easily stop up woollen blanket and produce sticking cylinder, cause the efficient that adds tobacco powder not only to be had a greatly reduced quality, and production efficiency has been caused greatly influence.
Chinese patent application has proposed " a kind of pair of net method produced the method for tobacco sheets by paper making method " for No. 200710034468.2, cigarette is broken, offal is worn into tobacco powder, offal is extracted active ingredient, collection slag by two paper manufacturing systems up and down fibre plate base of manufacturing paper with pulp out, tobacco powder is sprinkling upon one of them fibre plate base, again another fibre plate base is covered, then press dewatering, drying, extract spraying, drying and moulding.But, because up and down the fibre plate base only is to have extracted fibrous after the active ingredient by offal, extract is also only from the offal extraction, will cause the fragrance of reconstituted tobacoo and inhale distinguished the flavor of light, extract spraying back uneven components is spent greatly, so be not suitable for actual use.
Summary of the invention
Distinguished the flavor of light in order to overcome existing approaching composite papermaking method reconstituted tobacco and the existing reconstituted tobacco fragrance of process thereof and suction, extract spraying back uneven components is spent greatly, be not suitable for the defective of actual use, main purpose of the present invention has provided a kind of improved composite papermaking method type reconstituted tobacco and production method thereof, can overcome the defective of prior art.
