Abstract
The invention relates to a method for increasing a retention rate of a sizing agent in paper-making reconstituted tobacco. The method comprises the steps that calcium carbonate is added into a tobacco fragment sizing agent with a certain beating degree to enable the calcium carbonate and the tobacco fragment sizing agent to be fully adsorbed to form a compound; the compound is wrapped by sodium alginate to form a larger flocculation body; modification and stability treatment are performed on the surface of the flocculation body by aluminum sulfate; the modified calcium carbonate and the tobacco sizing agent are mixed with the help of a multi-element composite retention and drainage system and then processed into the reconstituted tobacco through papermaking, squeezing, coating, drying and slitting. By means of the method for increasing the retention rate of the sizing agent in the paper-making reconstituted tobacco, the binding force of the modified calcium carbonate and the sizing agent is enhanced, the modified calcium carbonate and the sizing agent are not likely to run off, and the retention rate of the modified calcium carbonate and the sizing agent in the reconstituted tobacco is high.
Description
[technical field]
The invention belongs to tobacco processing techniques, relate to papermaking-method reconstituted tobaccos production field, that one first utilizes tobacco chippings slurry to adsorb calcium carbonate formation compound, in conjunction with sodium alginate, coating modification is carried out to compound again, finally improve the method for papermaking-method reconstituted tobaccos slurry retention by polynary retention principal curvature system.
[background technology]
Reconstituted tobacco is also known as recombination tobacco leaf, reconstituted tobacoo, homogeneous tobacco leaf etc.The external use papermaking-method reconstituted tobaccos that begins one's study from mid-term in last century, domestic papermaking-method reconstituted tobaccos industry development is all more late with starting, but development speed and technological progress are all very fast, papermaking-method reconstituted tobaccos all has stronger functional form effect in saving raw tobacco material, lowering harm and decreasing coking, flavouring humectation, outstanding cigarette product style and features etc., and current papermaking-method reconstituted tobaccos has become the important and indispensable raw material of Chinese-style cigarette.But the shortcoming of papermaking-method reconstituted tobaccos also clearly, and ubiquity slurry retention is low, generally about 75%, need in process of production to consume a large amount of water, cause sewage disposal difficulty to strengthen, water resources problems and environmental problem are given prominence to.
For using water wisely, the plain boiled water produced in papermaking-method reconstituted tobaccos production process need recycle, but reconstituted tobacco produces offal used, fragment, the raw materials such as wood pulp, easily fiber fines is formed in pulping process, in the process of manufacturing paper with pulp, wet end runs off serious, not only cause the utilization rate of tobacco slurry low, the direct seed output and quality affecting reconstituted tobacco product, and the amount reproduction of micro fiber microorganism in plain boiled water can be caused, plain boiled water is made to produce peculiar smell, the suction taste of thin slice can be affected time serious, the number of times that recycles of plain boiled water is forced to reduce, have impact on industrial water comprehensive utilization ratio.In addition, calcium carbonate is additive important during reconstituted tobacco is produced, and effectively can improve physical property and the permeance property of sheet base, reduces reconstituted tobacco product tar and CO burst size.Because the particle diameter of calcium carbonate is very little, traditional directly joining method, in the process of manufacturing paper with pulp, wet end runs off serious, reduces reuse plain boiled water quality, adds sewage disposal energy consumption.In recent years, difficult point and focus that the research of slurry retention is reconstituted tobacco area research is always improved.
Research shows, slurry retention can be improved by adding modifier, it is that coating agent carries out parcel process to pearl filler that patent CN 103859576 A describes a kind of native potato starch that adopts, charge adjusting agent is used to regulate pulp fiber surface charge, the filler of parcel is added in tobacco slurry, to improve the method for baccy fiber and filler retention.Utilize the slurry retention of retention agent to a certain extent in improved sheet base, wherein shitosan, guar gum etc. have good retention and drainage effect.Patent CN 102715641 A describes a kind of by adding in handsheet step the method that calcium carbonate, wood pulp cellulose and guar gum improve reconstituted tobacco paper substrate quality in tobacco slurry.Patent CN 102715642 A describes a kind of raising and in tobacco slurry, adds calcium carbonate and guar gum to improve the method for reconstituted tobacco paper substrate quality in handsheet step.
Above-mentioned research shows, by adding wood pulp cellulose and using the measures such as the auxiliary agent such as shitosan, guar gum, although can improve slurry retention and sheet base physical index in sheet base to a certain extent.But mostly rest on experience accumulation aspect in practical application, and deposit the problems such as operability is in actual use strong, actual effect is not good, to cause in actual production process effective retention of tobacco slurry in sheet base still not reach expection requirement.The present invention first utilizes calcium carbonate to be adsorbed on tobacco chippings slurry and forms compound, in conjunction with sodium alginate, coating modification is carried out to compound again, finally improve slurry retention by polynary retention principal curvature system, improve calcium carbonate retention rate and high plain boiled water cyclic utilization rate simultaneously, reduce reconstituted tobacco product water consumption, study carefully according to our literature survey and yet there are no relevant report.

Step G: get and be mixed with multiple elements design retention aid and filtering aid system solution relative to the shitosan of tobacco slurry absolute dry mass 0.1%, the guar gum of 0.3%, the bentonite of 0.8%; Described multiple elements design retention aid and filtering aid system solution is added to tobacco mixed slurry, and stirs 40min under the condition of temperature 30 DEG C, stirring frequency 300rpm; Then through manufacturing paper with pulp, squeezing, be coated with, dry, cut and be processed into reconstituted tobacco.
In an embodiment of the present invention, the raw material that tobacco slurry is used be sieve in the tobacco chippings produced in beating and double roasting process, the offal produced in beating and double roasting process, throwing process fragment, discarded tobacco leaf mixing.
After testing, in reconstituted tobacco, the retention of slurry is 86.54%.
The water consumption of this production process is reduced to 27.48 tons of/ton of products.
In reconstituted tobacco, calcium carbonate retention rate is according to tobacco business standard " in YC/T 314-2009 cigarette paper carbonic acid calcium catalyst potentiometric titration ", and after testing, in reconstituted tobacco, calcium carbonate retention rate is 82.09%.
Gained reconstituted tobacco product physical and chemical index meets Standard.Aesthetic quality is through expert opinion, and fragrance is pure, flue gas is fine and smooth, thoroughly send out, and xylon gas is less, and excitant is less, inhales taste pure, comfortable.
Add in cigarette product by gained reconstituted tobacco by 10%, compared with the cigarette product not adding reconstituted tobacco, tar is propped up by 12.28mg/ and is reduced to 11.56mg/ and props up, and CO is propped up by 12.36mg/ and is reduced to 11.50mg/ and props up.
