Description
Technical field
The invention belongs to Sensory Quality of Cigarette to evaluate field, and in particular to a kind of side of quick predict cigarette smoking uniformity
Method.
Background technique
The suction uniformity of cigarette is an important factor for influencing Sensory Quality of Cigarette, is evaluating cigarette suction relaxation, pleased
Please the important indicator of sense, comfort.Cigarette aspirate uniformity mainly by cigarette in pipe tobacco occupied state, material uniformity shadow
It rings.Structure size, composition and the chemical component difference of pipe tobacco material will affect its filling capacity and combustion state, to influence to take out
Inhale impression.The different occupied states of same material also will affect the suction impression of cigarette.In general, consolidation is got in material filling,
Density is bigger, and resistance to suction when suction is also bigger.
Patent CN107436338A discloses a kind of evaluation method of dynamic stability during cigarette is burnt and sucked, and this method is logical
The artificial suction of one channel smoke sucking machine simulation is crossed, records the pressure data of every mouthful of suction to obtain dynamic resistance to suction data, to dynamic
Resistance to suction data carry out matrix analysis processing, to obtain resistance to suction estimation of stability index η.Patent 201611189773.4 discloses
It is a kind of burnt and sucked for cigarette during dynamic resistance to suction method for estimating stability and measurement device, equally use one channel smoke sucking machine
The artificial suction of simulation, by one-way analysis of variance dynamic resistance to suction data, so that evaluation is steady with dynamic resistance to suction between batch or batch
It is qualitative.Above two method has all used one channel smoke sucking machine, and the equipment requirement is high；And this method sample test and data processing
Process is complicated, and unparalleled property can not on-line testing.
Currently, there are two types of methods for evaluation cigarette suction uniformity.First is that passing through smoking machine and pressure using above-mentioned two kinds
Sensing equipment measurement aspirates resistance to suction by mouth, aspirates resistance to suction difference or puffing profile by mouth by comparison to evaluate suction uniformity；
Second is that smoothness when being smoked panel test by expert experiences difference artificially to evaluate cigarette suction uniformity.Both evaluation methods respectively have
Advantage and disadvantage, the former can be realized quantitative judgement, but equipment requirement is high, can not on-line testing；Subjective factor shadow of the latter by judging panel
Sound is larger, cannot achieve quantitative, transverse direction, rapid comparison.
The present invention is proposed in order to solve the above problem.
Summary of the invention
It is an object of the invention to overcome the technical disadvantages of existing method, a kind of quick predict cigarette smoking uniformity is provided
Method.The present invention quickly prejudges cigarette and aspirates uniformity by measuring and calculating density of tobacco rod distribution characteristics value.Of the invention
Method measures and calculates density of tobacco rod distribution characteristics value according to Cigarettesize, is judged according to obtained density of tobacco rod distribution characteristics value
Cigarette aspirates uniformity, easy to operate quick, is evaluating cigarette inherent quality stability and suction uniformity as a result accurately and reliably
Effective ways are provided.
A kind of method of quick predict cigarette smoking uniformity of the invention, is mainly realized by following scheme:
A method of prediction cigarette smoking uniformity, which is characterized in that according to the size of density of tobacco rod distribution characteristics value Y
Predict cigarette smoking uniformity, the density of tobacco rod distribution characteristics value Y measurement and calculating comprise the steps of:
1. take the cigarette sample of a certain specification multiple, according to cigarette specification by cigarette pipe tobacco filled section be divided into end section,
Non-compacted section and end endpiece are measured and are calculated respectively the end section, non-compacted section and end endpiece and cigarette entirety by standard
Mean density value and standard deviation, are denoted as respectively: the mean density value T of the cigarette end sectionJWith standard deviation TSD, described non-compacted
Section mean density value ZJWith standard deviation ZSD, the end endpiece mean density value WJWith standard deviation WSD, the cigarette global density is equal
Value MJ；
2. calculating density of tobacco rod distribution characteristics value Y:
3. whether 2. Y value that judgment step obtains is in (1.2,3.0) range；If Y value be in (1.2,3.0) range,
Then the cigarette smoking uniformity of this specification cigarette is qualified, and Y value is smaller, and cigarette smoking uniformity is better；If Y value not (1.2,
3.0) in range, then the cigarette smoking uniformity of this specification cigarette is to be improved, need in technique adjust end section, it is non-compacted
The density value of section and end endpiece.
Preferably, it is >=30 that the cigarette sample is multiple.
Preferably, the standard is " YC/T 476-2013 cigarette tobacco density measures microwave method ".
Preferably, it is 24.2 ± 0.2mm that the cigarette specification, which is Cigarette circumference,.
Preferably, nearly filter end need to be rejected when calculating end endpiece Density Distribution, standard deviation and density of tobacco rod entirety mean value
All Density Distribution data in 3mm.
Preferably, cigarette pipe tobacco filled section is divided into end section (firing tip), non-compacted section and end endpiece, middle-end
Head section and/or end endpiece length are the 1/2 of the smooth slot arc length of flattening disc；More preferably, end section and/or end endpiece length are
10-12mm.The flattening disc of cigarette machine is a kind of disk that can be cut down extra pipe tobacco, pipe tobacco is made to enter opium pipe as uniform plume
Shape accessory, smooth slot are the groove on flattening disc, make tight head end (end section or end endpiece) pipe tobacco more.In cigarette coiling process
In, the tight mouth that cigarette both ends are formed is convex portion, and the convex portion on tobacco rod of the groove by reduction on flattening disc makes
It obtains the full no bear in cigarette end and makes to connect mouth quality stabilization.
Beneficial effects of the present invention:
1, the Density Distribution Feature value of the cigarette of discovery in production practice suction uniformity and cigarette of the invention has close
Relationship, and have been surprisingly found that the Density Distribution Feature value of the preferably qualified cigarette of cigarette suction uniformity in (1.2,3.0) range.
2, method of the invention aspirates cigarette uniform according to the practical problem faced in product sensory quality assessment process
Property judgement be converted into pipe tobacco packed density distribution calculating and measurement, solve anticipation cigarette suction uniformity purpose, make
The judgment method for obtaining cigarette suction uniformity becomes simple.
3, method of the invention do not use smoking machine, it is not high to equipment requirement, it is easy to operate quickly, can on-line determination, knot
Fruit is accurate and reliable, is not influenced by artificial subjective factor.For cigarette physical quality and aesthetic quality's estimation of stability providing method branch
Support.
