Description
【Technical field】
The invention belongs to tobacco processing techniques, be related to papermaking-method reconstituted tobaccos production field, be one kind first with mixing slurry
Material absorption calcium carbonate forms compound, and coating modification is carried out to compound in conjunction with sodium alginate, is finally helped by polynary retention
Rate system is come the method that improves papermaking-method reconstituted tobaccos slurry retention.
【Background technology】
Reconstituted tobacco is also known as recombination tobacco leaf, reconstituted tobacoo, homogeneous tobacco leaf etc..Foreign countries begin one's study from last century mid-term and use
Papermaking-method reconstituted tobaccos, domestic papermaking-method reconstituted tobaccos industry development and starting are later, but development speed and technological progress are equal
Comparatively fast, papermaking-method reconstituted tobaccos are saving the sides such as raw tobacco material, lowering harm and decreasing coking, flavouring humectation, prominent cigarette product style and features
All there is stronger functional form to act in face, and current papermaking-method reconstituted tobaccos have turned into the important and indispensable original of Chinese-style cigarette
Material.But the shortcoming of papermaking-method reconstituted tobaccos is it is also obvious that generally existing slurry retention is low, typically 75% or so, in life
Need to consume substantial amounts of water during product, cause sewage disposal difficulty to increase, water resources problems and environmental problem are protruded.
It is using water wisely, produced plain boiled water needs to recycle in papermaking-method reconstituted tobaccos production process, but reconstruction cigarette
The raw materials such as leaf production offal, fragment, wood pulp used, easily form fiber fines, the wet end during manufacturing paper with pulp in pulping process
It is lost in seriously, not only causes the utilization rate of tobacco slurry low, directly affects the yield and quality of reconstituted tobacco product, and can make
The amount reproduction of micro fiber microorganism into plain boiled water, makes plain boiled water produce peculiar smell, and the suction taste of thin slice can be influenceed when serious, forces white
The recycling number of times reduction of water, have impact on industrial water comprehensive utilization ratio.Additionally, calcium carbonate be reconstituted tobacco production in it is important
Additive, can be effectively improved the physical property and permeance property of chip base, reduce reconstituted tobacco product tar and CO burst sizes.By
In the particle diameter very little of calcium carbonate, traditional directly joining method, wet end is lost in seriously during manufacturing paper with pulp, and reduces reuse plain boiled water matter
Measure, increased sewage disposal energy consumption.In recent years, improve difficult point that the research of slurry retention is always reconstituted tobacco area research and
Focus.
Research shows that can improve slurry retention by adding modifying agent, the A of patent CN 103859576 describe one kind
Use native potato starch carries out parcel treatment for coating agent to pearl filler, and pulp fiber is adjusted using charge adjusting agent
Surface charge, the filler that will be wrapped up is added in tobacco slurry, the method to improve baccy fiber and filler retention.Using retention
Agent improves the slurry retention in chip base to a certain extent, and wherein shitosan, guar gum etc. is imitated with preferable retention aid and filtering aid
Really.The A of patent CN 102715641 describe it is a kind of by handsheet step to tobacco slurry in add calcium carbonate, wood pulp cellulose
The method for improving reconstituted tobacco paper substrate quality with guar gum.The A of patent CN 102715642 describe a kind of raising in handsheet step
The rapid method for improving reconstituted tobacco paper substrate quality to calcium carbonate and guar gum is added in tobacco slurry.
The studies above shows, by adding wood pulp cellulose and using the measures such as the auxiliary agents such as shitosan, guar gum, although can
Improve slurry retention and chip base physical index in chip base to a certain extent.But experience product is rested in practical application mostly
Tired aspect, and there are problems that in actual use operability not by force, actual effect not, cause actual production process
Effective retention of tobacco slurry does not reach expected requirement still in middle chip base.The present invention is mixed in tobacco first with calcium carbonate absorption
Close and form compound on slurry, coating modification is carried out to compound in conjunction with sodium alginate, finally by polynary retention principal curvature system
To improve slurry retention, while improve calcium carbonate retention rate and plain boiled water cyclic utilization rate high, reduce reconstituted tobacco and produce
Product water consume, the literature survey according to us is studied carefully and yet there are no relevant report.
【The content of the invention】
[technical problem to be solved]
It is the defect for overcoming slurry retention in existing papermaking-method reconstituted tobaccos production process low, it is to be solved by this invention

Row coating modification is come the method that improves slurry retention in reconstituted tobacco chip base.
To achieve these goals, the present invention is pre-processed using mixed slurry fiber to calcium carbonate, and calcium carbonate is added
It is added in the tobacco mixed slurry of certain beating degree, calcium carbonate is formed compound with mixed slurry first, then using marine alga
Sour sodium carries out parcel to compound and is modified, and is made wadding aggressiveness, with aluminum sulfate to poly- surface modification of wadding a quilt with cotton.On this basis, use
The multiple elements design such as shitosan, guar gum and bentonite retention aid and filtering aid system processes slurry.Given birth to by existing papermaking-method reconstituted tobaccos
Production. art flow, papermaking-method reconstituted tobaccos are processed into through the process such as manufacturing paper with pulp, squeezing, be coated with, dry, cut.
