Description
Technical field
The invention belongs to reconstituted tobacco technology field, it is related to the measure side of suspension content in tobacco material water extract
Method.
Background technology
Suspension refers to the solid matter being suspended in water, including inorganic matter insoluble in water, organic matter and silt, glutinous
Soil, microorganism etc..Suspension usually turns into the hidden carrier of microorganism.Produce reality shows, in equal densities water extract, suspends
Thing is more, active ingredient less, quality it is poorer.Suspension content measure is extract degree of purity, quality control and extracted
The key index of process control.Reconstituted tobacco raw materials for production have offal, offal, tobacco cut, even cigarette ash rod, and raw material sources are wide
It is general, generally come from tobacco factory, the discarded leftover bits and pieces of Redrying Factory production process, reconstituted tobacco production process is related to extraction, concentration, net
Multiple feed liquid links such as change, coating, the suspension content of feed liquid, which directly affects, concerns process feed liquid clean-up effect, and active principle contains
Amount and extract solution quality, and then influence product Painting effect and final product quality.Therefore, suspension in tobacco material water extract is determined
Content is significant for reconstituted tobacco production process quality monitoring.
On the measure of middle suspension content in liquid, the Patents being related to are as follows：Chinese patent CN94192636.2

CN201310724959.5 discloses a kind of method of urban wastewater treatment firm Inlet and outlet water concentration of suspension quick detection；It is Chinese special
Sharp CN201410288543.8 discloses a kind of detection method of suspension content in sewage；Chinese patent
CN201410403317.X discloses suspension filter method in a kind of water.Wherein, CN94192636.2 method is to be based on dividing
Light luminosity absorbance, larger using statistical method, check and correction sample size, accommodation is limited.CN202101934U、
CN202886231U, CN201210436195.5, CN201310630304.1 are concentration of suspension detection means and instrument, its
Middle CN202101934U is the detection device based on Tyndall effect exploitation.201210210501.3、CN201310416413.3
Based on absorbance-test of the suspension content standard curve to suspension in oil-polluted water, test is time-consuming longer, while needs to make
Standard curve, waste time and energy.CN201310724959.5 is by establishing standard curve to urban wastewater treatment firm Inlet and outlet water water sample
Concentration of suspension is tested.CN201410288543.8 is similar with CN201410403317.X, and two methods test process is equal
It is relatively complicated, it is necessary to carry out testing preceding preparation, although the drying time 2h compared to convection oven method has been reduced, actual consumption
When it is still longer, instruct no instantaneity for line Quality Control and technique, as the practical significance applied in line method not
Greatly.
The test that the test of suspension is weighed using oven for drying after solution filtering substantially in tobacco material water extract at present
Method, but after filtering the method for testing dried it is time-consuming it is longer, process is cumbersome, operating error is relatively large, and in addition, tobacco is former
Expect that suspension easily combines with dissolubility polymer and colloidal substance (DCS) in Aqueous extracts, surveyed using traditional filtering, weight method
Fixed, part colloidal substance is also retained down as suspension, and the test result degree of accuracy is inadequate, low precision, poor reproducibility；If adopt
With spectrophotometric absorbance method, because the fluctuation of tobacco material composition is big, product formula is changed every time, is required for remaking standard
Working curve, even produce reality shows that same composition of raw materials composition fluctuation is also bigger, influence accuracy, the essence of measure
Degree, reappearance.
The content of the invention
It is an object of the invention to solve the above-mentioned problems of the prior art and deficiency, there is provided one kind can quickly, accurately
The method of suspension content in the tobacco material water extract of ground measure papermaking-method reconstituted tobaccos production, to improve extract degree of purity
And quality.
The purpose of the present invention is achieved through the following technical solutions：
The assay method of suspension content, step are as follows in a kind of tobacco material water extract：
(1) papermaking-method reconstituted tobaccos production process tobacco material water extract is taken, extract is determined using karr-Fei Xiu methods
Moisture CW,；
(2) using the Brix angle value S in Brix Brix degrees instrument measure tobacco material water extractC；
(3) suspension content C in tobacco material water extract is calculatedSS, calculation formula is as follows：
CSS(%)=100-CW-SC。
Tobacco material of the present invention is the one or more in smoked sheet, pipe tobacco, cigarette ash rod, offal.
The inventive method is more suitable for surveying using karr-Fei Xiu Moisture Meters measure extract solution moisture, Karl_Fischer method
Determine the moisture of tobacco material Aqueous extracts, avoiding oven method measuring extract solution moisture, higher (substantial amounts of thermal sensitivity is waved in extract solution
Hair property removed into branch in drying course) error, using Brix Brix degrees instrument determine extract solution Brix angle value, that is, extract
The water solubility of liquid contains admittedly, and then calculates suspension content in tobacco material water extract.
Compared with prior art, suspension contains in the tobacco material water extract of present invention measure papermaking-method reconstituted tobaccos production
The minute of amount is short, accuracy is high, precision is high, data reappearance is good, high sensitivity, can optimizing tobacco raw material water extract carry
Take, concentrate, allocating and using technique, improving extract degree of purity and quality.
