Abstract
The invention discloses a method for papermaking method reconstituted tobacco by replacing wood pulp fibers through cotton stalk bark fibers and belongs to the field of reconstituted tobacco. According to the method, the cotton stalk bark fibers replace the wood pulp fibers to serve as an outer fiber material, tobacco stems and tobacco leaf fragments serve as tobacco raw materials, tobacco pulp, the cotton stalk bark fibers and filler are subjected to mixing and papermaking to form reconstituted tobacco base pieces, and the required reconstituted tobacco is obtained after coating of coating liquid and drying. According to the papermaking method reconstituted tobacco prepared through the method, waste in agricultural production is processed, cost is reduced, environment protection is achieved, the utilization rate of cotton stalk resources is increased, and good physical characteristics and sensory quality of the papermaking method reconstituted tobacco are kept.
Description
Technical field
The invention belongs to reconstituted tobacco technical field, specifically the hide fiber that grows cotton replaces wood pulp cellulose to prepare the method for papermaking-method reconstituted tobaccos.
Technical background
China is Chan Mian big country in the world, and cotton stalk 225-250kg is produced in one mu of cotton field, and skin zone accounts for 26%, and the cotton stalk annual production of China reaches 1,530 ten thousand tons, has cotton straw skin 4,000,000 tons, and therefore the cotton straw skin resource of China is extremely abundant.And cotton stalk is as agricultural residue, its part is used as fuel and burns by rural area mostly, and all the other stack in ground, field, and with the passing of time going bad becomes unserviceable waste material.Cotton stalk bark is a kind of excellent bast long fiber of growth on cotton stalk surface, and it belongs to high-tenacity low-elongation fiber.The main path that current cotton stalk develops has: (1) papermaking and packing case cardboard.Cotton stalk is used as paper making raw material, and its quality far wins straw and straw, can manufacture solid durable brown paper and industrial wrapping paper; (2) particieboard is processed.The chemical composition of cotton stalk is similar to broad-leaved wood, therefore can replace timber processing artificial boards material with cotton stalk, cotton stalk particieboard not only have do not collapse do not split, the inexpensive advantage such as durable, and in producing, there is no the problem of contaminated environment; (3) processing fiber plate.With cotton stalk processing fiber plate, aliquation, price are not low, can make interior decoration, lodge plate, the inside panel of shipping vehicle and the decorative panel etc. of various furniture; (4) processing building material.Make the aggregate of cement products with cotton stalk, as cotton stalk cement decorative plate, cement tile etc., have light weight, inexpensive, firm, heat insulation and insulation advantage; (5) cotton stalk fermented feed.
Reconstituted tobacco is also known as recombination tobacco leaf, homogeneous tobacco leaf.Primarily of offal fragment, offal or discarded tobacco leaf, plus fiber, filler and other additive composition.The advantages such as density is little, Filling power is high owing to having for papermaking-method reconstituted tobaccos, become that silk rate is high, machining property good and Modulatory character is good, have become the main method of domestic and international production reconstituted tobacco.Papermaking-method reconstituted tobaccos through extracting, concentrated, perfuming, separation, pull an oar, manufacture paper with pulp, the technical process such as oven dry, its for improve tobacco product quality, reduce tar content, change smoke components, save pipe tobacco consumption, stablize cigarette composition and play a very important role.
The plus fiber that existing papermaking-method reconstituted tobaccos adds in producing is mostly wood pulp, comprises softwood pulp and hardwood pulp.At present; its wood pulp cellulose used mostly is the wood pulp cellulose of external import; along with the shortage of timber resources in world wide and the enhancing of environmental protection consciousness; developing how new pulp fiber replaces wood pulp cellulose imperative; to alleviate the present situation of timber resources scarcity, for cotton stalk bark fibre expands new purposes.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of simple, feasible, stay-in-grade cotton stalk bark fibre and replaces wood pulp cellulose to prepare the method for papermaking-method reconstituted tobaccos.
For solving the problems of the technologies described above, the present invention takes following technical scheme to be achieved.
Unless otherwise indicated, percentage of the present invention is mass percent.
Cotton stalk bark fibre replaces a method for the papermaking-method reconstituted tobaccos of wood pulp cellulose, and concrete steps are as follows:
(1) cotton stalk bark fibre preparation: the segment clean cotton stalk bark fiber cutting machine being cut into 2-4cm, joins NaOH, H of 0.2-0.8% by solid-liquid mass ratio 1:20 by cotton stalk bark
2o
2, urea mixed solution in, at 70 DEG C, soak 65min; Then soak with clear water, wash, more tentatively separate fibre with Double-helix thread rolling divider, obtain cotton stalk bark fibre;
(2) cotton stalk bark slurry preparation: thicken to 3.5% by tentatively separating fine cotton stalk bark fibre, carry out defibrination with disc mill, obtain cotton stalk bark slurry, it is 20 ± 2 ° of SR that beating degree controls;
(3) raw material abstraction: offal, tobacco leaf fragment are carried out independent separating and extracting according to mass ratio 4:6 hot water, extraction temperature is 55 ± 2 DEG C, extraction time is 40 ± 2min, carries out Separation of Solid and Liquid respectively, obtains tobacco stem extract, offal fragment extract, tobacco stalk fibre, offal chopped fiber;
(4) tobacco pulp slurry preparation: above-mentioned tobacco stalk fibre, offal chopped fiber are mixed, thickens to 3.0%, carry out defibrination with disc mill, obtain tobacco mixed slurry, it is 34 ± 2 ° of SR that beating degree controls;
(5) substrate preparation: by tobacco mixed slurry, cotton stalk bark slurry and filler by tobacco mixed slurry (78-84) part: cotton stalk bark slurry (8-14) part: the absolute dry mass ratio of filler 8 parts manufactures paper with pulp into reconstituted tobacco substrate, wherein filler is precipitated calcium carbonate, and grain shape is fusiform;
(6) coating fluid preparation: tobacco stem extract, offal extract are mixed than 2:8 by absolute dry mass, the concentration of Vacuum Concentration to 40 ± 1%, obtains concentrate, adds the essence and flavoring agent of mass ratio 1.5%, obtains coating fluid;
(7) reconstituted tobacco preparation: the coating fluid prepared by step (6) carries out conventional coating, oven dry to substrate prepared by step (5), control the moisture of finished product 10-12%, it is 39-41% that spreading rate controls.
Device therefor of the present invention is standard product, and market can be bought.
The invention has the beneficial effects as follows: first, papermaking-method reconstituted tobaccos prepared by the present invention is additional string with cotton stalk bark fibre, replaces wood pulp cellulose to prepare papermaking-method reconstituted tobaccos, can effectively utilize waste resource, and raw material is easy to get; Secondly, the stock quality that cotton stalk bark fibre is made is similar to outsourcing wood pulp, and cost is well below outsourcing wood pulp cellulose; In addition, by grasping the whole process of cotton stalk bark pulping process, the quality fluctuation of cotton stalk bark fibre is effectively controlled; Finally, the papermaking-method reconstituted tobaccos be made up of cotton stalk bark fibre raw material, compared with the wood pulp cellulose papermaking-method reconstituted tobaccos prepared under same process condition, has physical characteristic and the better advantage of aesthetic quality.
