Description
Technical field
The invention belongs to reconstituted tobacco technical field, refer to a kind of tobacco material extracting process of papermaking-method reconstituted tobaccos particularly.
Background technology
Papermaking-method reconstituted tobaccos refers to the requirement according to reconstituted tobacco composition of raw materials, tobacco waste (as offal, offal, tobacco leaf fragment etc.) is soaked extraction as starting material with water, be decomposed into DDGS and soluble thing, soluble thing makes the substrate as body paper with the method for similar papermaking, then on substrate, add the DDGS after concentrated and additive, then through super-dry, point cut into reconstituted tobacco.Reconstituted tobacco at reduction cigarette cost, economize in raw materials, improve in cigarette quality and all have incomparable advantage, just obtain since coming out from the 1950's and develop rapidly, current tobacco sheets by paper making method has become one of core technology of Ge great tobacco company, is the important formula composition in cigarette.
In the production process of tobacco sheets by paper making method, the extract and separate of raw material guarantees an important process step of product yield, quality and cost.Mainly there is following defect in existing tobacco material extracting process: (1) tobacco material recovery rate is not high, directly determines the quantity not sufficient reverting to on-chip tobacco material in operation below, and then affect the quality of reconstituted tobacco; (2) tobacco material extracts not exclusively, and can enter sewage disposal system along with backwater runs off in the pulping process in later stage, increase the load of sewage disposal, production cost also increases thereupon.
Summary of the invention
For overcoming the deficiencies in the prior art, object of the present invention is exactly the tobacco material extracting process that will provide a kind of papermaking-method reconstituted tobaccos.The method by adopting ultrasonic assistant decompression extractive technique in the production process of papermaking-method reconstituted tobaccos raw material abstraction, the efficiency of extraction can be improved, improve the organoleptic quality of reconstituted tobacco, carry high product yield, can also sewage treatment load be reduced simultaneously, reduce production cost.
For achieving the above object, the tobacco material extracting process of a kind of papermaking-method reconstituted tobaccos provided by the invention, comprises the steps:
(1) be, with water extractant, be that 1:3 ~ 1:6 adds in extractor by tobacco material and water according to feed liquid mass ratio, stir under temperature is 30 ~ 70 DEG C of conditions, after ultrasonic extraction 15 ~ 50min, be extracted thing a;
(2), by the extract a obtained after step (1) process carry out Separation of Solid and Liquid, obtain solid tobacco material residue b and filtrate c;
(3), by the filtrate c that step (2) obtains carry out Vacuum Concentration, until concentrate solid content is 30 ~ 50%, namely obtain the tobacco material extract of reconstituted tobacco.
Further, the tobacco material in described step (1) is offal or the broken end of tobacco leaf, and the broken end of described tobacco leaf comprises offal and tobacco fragment.
Further, decompressor is adopted to keep pressure in extractor to be 50 ~ 90Kpa in described step (1).
Further, in described step (1), ultrasonic power is 50 ~ 600w.
Further, Vacuum Concentration carries out under be-0.09 ~ 0Mpa and temperature being the condition of 50 ~ 100 DEG C in vacuum in described step (3).
The invention has the advantages that:
(1), the present invention by have employed ultrasonic assistant decompression extractive technique in the production process of papermaking-method reconstituted tobaccos raw material abstraction, the vibration of this ultrasonic wave can strengthen the permeability that solvent enters plant cell, the mass transfer rate of strengthening extract between two-phase medium;
(2), the present invention adopts ultrasonic assistant decompression extractive technique to produce cavitation bubble, bubble strenuous exercise forms powerful shearing force to cell, particularly form local assault ripple and high-speed jet effect during bubble collapse, plant cell can be made to break, accelerate the release of cellular content;
(3), decompressing inner ebullition method of the present invention is a kind of low temperature extraction process of effective component fast, decompression is conducive to improving plant draft amount, make tissue looseness, be conducive to leaching, and due to decompression Extracting temperature relatively low, avoid active ingredient to be subject to high temperature, also can reduce the stripping of some large molecular impurities.
In general, the inventive method is reasonable, simple to operate, Be very effective, and extractive technique improves the efficiency of extraction, improves the organoleptic quality of reconstituted tobacco, can reduce sewage treatment load simultaneously, improves the yield of product.
