Description
Technical field
The invention belongs to papermaking-method reconstituted tobaccos technical field, be specifically related to a kind of reconstituted tobacco raw material and extract concentrated solution
Purification method.
Background technology
Papermaking-method reconstituted tobaccos mostly uses two-step process at present, owing to its raw material sources are complicated, after water extraction, carries
Take and concentrated solution can remove some fine particles such as dust, fiber fines etc., also have some macromolecular substances such as property protein, really
Glue, cellulose, hemicellulose, lignin etc., these materials are except the concentration in production technology, painting process are had negative effect
Outward, also sensory quality of reconstituted tobacco leaves can be had a negative impact, such as miscellaneous QI weight, stimulate the problems such as big.Therefore, the remove impurity of extracting solution
The always important ring in reconstituted tobacco production technology, centrifugal remove impurity, screen cloth are filtered, machinery sedimentation, flocculation treatment etc. process
Mode is the major way that reconstituted tobacco manufacturing enterprise uses.But all there is certain shortcoming in aforesaid way, as screen cloth filters easily
Blocking, centrifugal remove impurity energy consumption is higher, and machinery sedimentation is the longest, efficiency is low；Flocculating sedimentation is inefficient.It addition, above-mentioned process side
Formula is to process in extracting solution link mostly, and treating capacity is relatively big, relatively costly.
ZTC1+1 natural clarifying agent is made up of two kinds of components of A, B, is the natural high molecular substance extracted from food, its
Clarification principle is to use up-to-date " 1+1 clarification technique ", and one group is played main flocculation, and another component then plays auxiliary flocculation, adds
Fast clarifying process, can thoroughly remove the instability in the tannin of extracting solution, albumen, oils and fats, suspension solid content impurity, solution system
Impurity, but it does not produce impact to compositions such as polysaccharide, polypeptide, aminoacid, faster than traditional clarification process 2-5 times.ZTC1+1 is natural
Clarifier has safety height, noresidue, nontoxic advantage.This technology is tried out in pharmaceutical factory, over one hundred of the whole nation at present, user
Just, it is not necessary to add equipment, and consumption is little, operation simplifies, with short production cycle, expense is low, has fairly obvious economic benefit.
The present invention utilizes ZTC1+1 natural clarifying agent reconstituted tobacco raw material to extract concentrated solution, and correlation technique has no report.
Summary of the invention
The invention aims to solve the deficiencies in the prior art, it is provided that a kind of reconstituted tobacco raw material extracts concentrated solution
Purification method, Nicotiana tabacum L. extraction concentrated solution, after ZTC1+1 natural clarifying agent processes, can effectively remove the egg extracted in concentrated solution
The macromolecular substances such as white matter, pectin, can be obviously improved the quality of concentration, and then improve the quality of papermaking-method reconstituted tobaccos.
The technical solution used in the present invention is as follows:
A kind of reconstituted tobacco raw material extracts the purification method of concentrated solution, comprises the steps:
Step (1), the extraction of raw material: by reconstituted tobacco raw material reconstituted tobacco raw material in mass ratio: water=1:5 ~ 1:10 adds water,
60-75 DEG C, extract 30-60 min, solid-liquid separation, obtain extracting solution and solid fraction；
Step (2), the concentration of extracting solution: the extracting solution of step (1) is concentrated into density 1.20 ± 0.02 g/ with Rotary Evaporators

Water=1:4 ~ 1:6, first with a small amount of deionized water furnishing pasty state, then press compound concentration add requirement deionized water, swelling 24
H, filters with double gauze after stirring, obtains 0.25 ~ 1% viscose A；ZTC1+1 natural clarifying agent B component: the most natural
Clarifier II type B component: 1% acetic acid=1:5, with a small amount of concentration 1% acetate dissolution and stir into pasty state, then presses compound concentration and adds and need
1% acetic acid to be measured, swelling 24 h, filter with double gauze, obtain 0.25 ~ 1% viscose B；
Step (4), the pretreatment of concentrated solution: the concentrated solution of step (2) gained is transferred in settling tank, dispersed with stirring, limit is stirred
Limit adds ZTC-pretreating agent extremely final concentration of 500-1000 ppm in mass ratio, 50 DEG C ~ 80 DEG C, is incubated 3-6 h, layering；
Step (5), the clarifying treatment of concentrated solution: in the settling tank of step (4), dispersed with stirring, the most slow
Slowly add the viscose B to final concentration of 500 ~ 1000 ppm of step (2) gained, temperature 50-70 DEG C, stir every 30 min
Once, 1-2h is processed；Dispersed with stirring, adds viscose A while stirring, makes viscose A: viscose B final concentration ratio is 0.5 ~ 2,
Then stir once every 30-60 min, after stirring 2 times, stand 4-8 h；
Step (6), the separation of scavenging solution: siphon supernatant, filter and i.e. obtain scavenging solution.
Reconstituted tobacco raw material described in step (1) be cabo, tobacco fragment, offal, flue dust rod any one of or wherein
Several mixture.
ZTC1+1 natural clarifying agent described in step (3) can be II type or III type or IV type.
ZTC-pretreating agent described in step (4) can be ZTC-pretreating agent A or ZTC-pretreating agent B.The present invention with
Prior art is compared, and it has the beneficial effect that Nicotiana tabacum L. extraction concentrated solution, after ZTC1+1 natural clarifying agent processes, can effectively be removed
Extract the macromolecular substances such as the protein in concentrated solution, pectin, the quality of concentration can be obviously improved, and then improve paper process again
Make the quality of Nicotiana tabacum L., have easy to use, efficiency is high, the production cycle is sour, low cost and existing process matching degree high, entirely without
Poison, noresidue, the advantage such as good in economic efficiency.
