Abstract
The invention belongs to the technical field of papermaking-method reproduced tobaccos and particularly relates to a determining method of hot-water soluble matters of the papermaking-method reproduced tobaccos. The determining method is characterized in that the papermaking-method reproduced tobaccos are grinded into particles with a certain granularity and are placed into water; then the mixture is heated and reflowed for a certain time, and then is cooled and filtered; and the content of the hot-water soluble matters is obtained by the mass difference of a test sample initial mass and a filtered residue mass. The determining method disclosed by the invention has the characteristics of simplicity in operation, accuracy and good stability, and is particularly suitable for determining the hot-water soluble matters of the papermaking-method reproduced tobaccos.
Description
Technical field:
The invention belongs to the papermaking-method reconstituted tobaccos technical field, be specifically related to a kind of assay method of papermaking-method reconstituted tobaccos hot water solvend.
Technical background:
Papermaking-method reconstituted tobaccos is a kind of important cigarette material, adds an amount of reconstituted tobacco in pipe tobacco, can play the effect that improves cigarette physical property, lowering harm and decreasing coking, also can save smoke material simultaneously, reduce the cigarette cost.Along with range of application and the application percentage of papermaking-method reconstituted tobaccos in Chinese-style cigarette progressively strengthens, cigarette enterprise has proposed requirements at the higher level to the quality of reconstituted tobacco with corresponding quality monitoring means and technology.
Papermaking-method reconstituted tobaccos is a kind of tobacco material that uses the paper making forming method to make, fundamentally, be exactly separate, a process of combination again.After separating the raw materials such as the offal refer to for the manufacture of reconstituted tobacco, fragment, cigarette ash and extracting with hot-water soak, be separated into water-soluble substance and water-insoluble, water-insoluble utilizes papermaking process and makes the sheet base section, and water-soluble substance must turn back on the sheet base through concentrated again.Turn back to process on the sheet base in conjunction with referring to the water-soluble substance that obtains in the above-mentioned detachment process again, only have by cohesive process again, could form final reconstituted tobacco finished product.Reconstituted tobacco hot water solubles content refers to the reconstituted tobacco finished product after superheated water extracts fully, and water-soluble substance accounts for the percentage composition of reconstituted tobacco dry weight.Reconstituted tobacco hot water solvend can reflect what of water-soluble substance of the sheet base section that turns back to, the height that can indirectly reflect spreading rate, and have influence on the qualities such as physics, chemistry, flue gas and sense organ of reconstituted tobacco, so the hot water solubles content is very important index of papermaking-method reconstituted tobaccos.
At present, what of amount that spreading rate is estimated the hot water solvend that returns in the cohesive process are again calculated by online production by reconstituted tobacco manufacturing enterprise, and its computing formula is: spreading rate=[(finished product over dry quantitatively-sheet base over dry is quantitative)/sheet base over dry is quantitative] * 100%.And for reconstituted tobacco applying unit---cigarette enterprise, then have no idea to obtain the relevant information of spreading rate aspect.Chinese patent (CN 102607986 A) discloses a kind of method of determined off-line papermaking-method reconstituted tobaccos finished product spreading rate, and the method is by calculating spreading rate to sheet base and finished product reconstituted tobacco mensuration extraction ratio respectively.But the method need to be tested the sheet base, and in practical operation because cigarette enterprise is difficult to obtain the sheet base, thereby so that this method be difficult to carry out.
Summary of the invention:
For the problems referred to above, the purpose of this invention is to provide a kind of assay method of papermaking-method reconstituted tobaccos hot water solvend, the method is easy and simple to handle, quick and precisely.
The present invention grinds to form the particle of certain particle size with papermaking-method reconstituted tobaccos, places water, adds the hot reflux certain hour, and cooling is also filtered, and tries to achieve the hot water solubles content by the difference of residue quality after sample initial mass and the filter.
For achieving the above object, the present invention takes following technical scheme:
1. sample is pulverized with comminutor, crosses 40 mesh sieves;
2. working sample moisture w;
3. filter paper was placed (100 ± 1) ℃ oven drying 1 hour, take out; Place exsiccator to let cool (about 30 minutes), take out weighed quality m
2
4. take by weighing about 2g(m
1) sample in the 250mL conical flask, add 100mL distilled water;
5. conical flask is placed on the electric jacket, connect condenser pipe, add hot reflux 1h, stopped heating takes out the conical flask cooling;
6. the filter paper with weighed quality places in the Buchner funnel, vacuumizes, and the material in the conical flask is poured on the filter paper of Buchner funnel, with distilled water all residues in the conical flask is cleaned to filter paper, and cleans filter residue 3 times, each 30mL;
7. shift the filter paper that fills residue, carefully twice filter paper of doubling is blown away in baking oven to prevent residue; Filter paper was placed (100 ± 1) ℃ oven drying 3 hours, and took out, place exsiccator to cool off 30min, take out sample, quick weighed quality m
3
8. the result calculates.Percentage composition in the hot water solvend of butt is calculated by formula (1):
In the formula:
m
1Be the quality of sample, the g of unit; m
2Be the quality of filter paper, the g of unit;
m
3Be the quality of residue and filter paper, the g of unit; W is the moisture of sample.
The invention has the advantages that: method is easy, quick and precisely, good reproducibility, be applicable to the mensuration of hot water solvend in the papermaking-method reconstituted tobaccos.
Embodiment
Below in conjunction with instantiation the inventive method is described in detail as follows:
Get certain brand papermaking-method reconstituted tobaccos sample, pulverize with comminutor, cross 40 mesh sieves, and working sample moisture w; Filter paper was placed (100 ± 1) ℃ oven drying 1 hour, and took out, place exsiccator to let cool (about 30 minutes), take out weighed quality m
2Take by weighing about 2g(m
1) sample in 250 mL conical flasks, add 100mL distilled water; Conical flask is placed on the electric jacket, connect condenser pipe, add hot reflux 1h, stopped heating takes out the conical flask cooling; The filter paper of weighed quality is placed in the Buchner funnel, carefully the limit of filter paper is spooled, with the wetting filter paper of distilled water, make filter paper be close to Buchner funnel; Open vacuum pump, begin to vacuumize, regulation safety valve can be aspirated smoothly sample solution and can filter paper do not broken because negative pressure is excessive, and the material in the conical flask is carefully poured on the filter paper of Buchner funnel; With distilled water all residues in the conical flask are cleaned to filter paper, and clean filter residue at least 3 times, each 30mL; Open the safety-valve, cut off vacuum-pump power supply and carefully shift the filter paper that fills residue, carefully twice filter paper of doubling is blown away in baking oven to prevent residue; Filter paper was placed (100 ± 1) ℃ oven drying 3 hours, and took out, place exsiccator to cool off 30min, take out sample, quick weighed quality m
