Abstract
The invention relates to a method for increasing the pulp retention rate of papermaking-process reconstituted tobaccos. According to the method, calcium carbonate is added to mixed pulp with a certain beating degree, the calcium carbonate and the mixed pulp are fully adsorbed to form a compound coated with sodium alginate, a larger flocculation body is formed, then surface modification and stabilization treatment are performed on the flocculation body with aluminum sulfate, modified calcium carbonate is mixed with pulp by the aid of a multi-element compound retention and drainage aid system, and then the reconstituted tobaccos are formed through papermaking, squeezing, coating, drying and cutting processing. With the adoption of the method, the bonding force of the modified calcium carbonate to the pulp is increased, the loss cannot occur easily, and retention rates of the modified calcium carbonate and the pulp in the reconstituted tobaccos are high.
Description
[technical field]
The invention belongs to tobacco processing techniques, relate to papermaking-method reconstituted tobaccos production field, that one first utilizes mixed 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 mixing 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.
[summary of the invention]
[technical problem that will solve]
