Description
[technical field]
The invention belongs to tobacco processing techniques, relate to papermaking-method reconstituted tobaccos production field, be a kind of first with
Cabo slurry absorption calcium carbonate forms complex, in conjunction with sodium alginate, complex is carried out coating modification,
After improve the method for slurry retention in papermaking-method reconstituted tobaccos by polynary retention principal curvature system.
[background technology]
Reconstituted tobacco is also known as recombination tobacco leaf, reconstituted tobacoo, homogenizing Nicotiana tabacum L. etc..Abroad open from mid-term in last century
Begin research use papermaking-method reconstituted tobaccos, and domestic papermaking-method reconstituted tobaccos industry development and starting are the most later, but
Development speed and technological progress are all very fast, and papermaking-method reconstituted tobaccos is saving raw tobacco material, lowering harm and decreasing coking, increasing
The aspects such as fragrant humectation, prominent cigarette product style and features all have stronger functional type effect, current paper process
Reconstituted tobacco has become the raw material that Chinese-style cigarette is important and indispensable.But the shortcoming of papermaking-method reconstituted tobaccos
It is also obvious that it is low generally to there is slurry retention, typically about 75%, need in process of production to consume greatly
The water of amount, causes sewage disposal difficulty to strengthen, and water resources problems and environmental problem highlight.
For using water wisely, in papermaking-method reconstituted tobaccos production process, produced plain boiled water needs to recycle, but
Reconstituted tobacco produce used by cabo, fragment, the raw material such as wood pulp, pulping process is easily formed tiny fibre
Dimension, during manufacturing paper with pulp, wet end runs off serious, and the utilization rate not only causing tobacco slurry is low, directly affects again
Make yield and the quality of tobacco leaf product, and the amount reproduction of micro fiber microorganism in plain boiled water can be caused, make
Plain boiled water produces abnormal flavour, can affect the suction taste of thin slice, force the recycling number of times of plain boiled water to reduce, shadow time serious
Ring industrial water comprehensive utilization ratio.Additionally, calcium carbonate is additive important in reconstituted tobacco production, energy
It is effectively improved physical property and the permeance property of chip base, reduces reconstituted tobacco product tar and CO burst size.By
The least in the particle diameter of calcium carbonate, tradition directly joining method, during manufacturing paper with pulp, wet end runs off serious, reduces
Reuse plain boiled water quality, add sewage disposal energy consumption.In recent years, the research of slurry retention is improved the most again
Make difficult point and the focus of Nicotiana tabacum L. area research.
Research shows, can improve slurry retention by adding modifying agent, and patent CN 103859576A introduces
A kind of employing native potato starch is that coating agent carries out parcel process to pearl filler, uses electric charge to adjust
Joint agent regulation pulp fiber surface charge, adds in tobacco slurry by the filler of parcel, to improve baccy fiber
Method with filler retention.Retention agent is utilized to improve the slurry retention in chip base to a certain extent, its
Middle chitosan, guar gum etc. have preferable retention and drainage effect.Patent CN 102715641A describes one
Kind improve and reproduce cigarette by adding calcium carbonate, wood pulp cellulose and guar gum in tobacco slurry in handsheet step
The method of leaf paper substrate quality.Patent CN 102715642A describes a kind of raising in handsheet step to tobacco pulp
The method that in material, interpolation calcium carbonate and guar gum improve reconstituted tobacco paper substrate quality.
The studies above shows, by adding wood pulp cellulose and using the measures such as the auxiliary agent such as chitosan, guar gum,
Although slurry retention and chip base physical index in chip base can be improved to a certain extent.But in actual application
Mostly rest on experience accumulation aspect, and deposit that operability in actual use is strong, actual effect
The problem such as the best, causes in actual production process effective retention of tobacco slurry in chip base still not reach pre-
Phase requirement.The present invention forms complex first with titanium pillaring solution on cabo slurry, in conjunction with sodium alginate
Complex is carried out coating modification, finally improves 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, according to
Our literature survey is studied carefully and be yet there are no relevant report.
