Problems solved by technology

These two evaluation methods have their own advantages and disadvantages. The former can achieve quantitative judgment, but requires high equipment and cannot be tested online; the latter is greatly affected by the subjective factors of the judges, and cannot achieve quantitative, horizontal, and rapid comparison.

Embodiment 1

[0023] Example 1: Prediction of the smoking uniformity of four cigarette samples with shredded widths of 0.9, 1.0, 1.1, and 1.2 mm.

[0024] Four kinds of cigarette samples with shredded widths of 0.9, 1.0, 1.1, and 1.2mm are rolled into cigarettes with a circumference of 24.2±0.2mm and a length of (24.0+60.0)±0.5mm according to the weight of the same cigarette . The arc length of the leveling groove of the leveling disc of the cigarette machine used is 24 mm, of which the end section is 12 mm, the non-compacted section is 36 mm, and the end section is 12 mm.

[0025] Take a number of mixed shredded cigarette samples with a cut width of 0.9 (number: sample 1), and randomly divide the cigarette samples into three groups, each group has 50 cigarettes, and the first group of cigarette samples is according to the standard The method of YC / T476-2013 measures and calculates the average density T of the tip of the cigarette respectively J and standard deviation T SD , the average ...

Embodiment 2

[0034] Example 2: Prediction of smoking uniformity of three kinds of cigarette samples whose blending ratios of cut stems are 8wt%, 12wt%, and 16wt%.

[0035] Take 8wt%, 12wt%, and 16wt% mixed cut stem samples, and roll them respectively according to the same cigarette weight to make cigarettes with a circumference of 24.2±0.2mm and a length of (30.0+54.0)±0.5 mm cigarettes. The arc length of the leveling groove of the leveling disc of the cigarette machine used is 22mm, of which the end section is 11mm, the non-compacted section is 32mm, and the end section is 11mm.

[0036] Take a number of rolled cigarette samples with a cut stem blending ratio of 8wt%, and randomly divide the cigarette samples into three groups. The number of cigarettes in each group is 40. The first group follows the standard YC / T 476-2013 The method is used to measure and calculate the average density T of the end section of the cigarette respectively J and standard deviation T SD , the average densit...

Embodiment 3

[0045] Example 3: Prediction of smoking uniformity of D brand cigarette samples produced by three cigarette factories A, B and C.

[0046] The circumference of the D brand cigarette sample produced by the three cigarette factories A, B and C is 24.2±0.2mm, and the length of the cigarette is (27.0+57.0)±0.5mm. The arc length of the flattened groove of the flattened disc of the cigarette machine used is 22 mm, of which the length of the end section is 11 mm, the non-compacted section is 35 mm, and the end section is 11 mm.

[0047] Take several cigarette samples of brand D cigarettes produced by A Cigarette Factory, and divide the cigarette samples into three groups at random, and the number of cigarettes in each group is 50. The same as in Example 1, the first group of cigarette samples is measured and calculated according to the YC / T 476-2013 method for the characteristic value Y value of the cigarette density distribution, and the second group of cigarette samples is measured...

Abstract

The invention discloses a method of rapidly predicting smoking uniformity of a cigarette. Smoking uniformity of a cigarette is predicted according to a cigarette density distribution characteristic Y,if Y is within (1.2,3.0), the cigarette of the specification is qualified in smoking uniformity, and the smaller the Y, the better the smoking uniformity of the cigarette. The method is easy and rapid to operate, can measure online, and delivers an accurate, reliable result.

Description

technical field [0001] The invention belongs to the field of cigarette sensory quality evaluation, in particular to a method for quickly predicting the smoking uniformity of cigarettes. Background technique [0002] The smoking uniformity of cigarettes is an important factor affecting the sensory quality of cigarettes, and an important indicator for evaluating the ease, pleasure and comfort of cigarette smoking. The smoking uniformity of cigarettes is mainly affected by the filling state of shredded tobacco inside cigarettes and the uniformity of materials. The structural size, composition and chemical composition of cut tobacco materials will affect their filling capacity and combustion state, thereby affecting the smoking experience. Different filling states of the same material will also affect the smoking experience of cigarettes. Generally speaking, the tighter and denser the material filling, the greater the suction resistance during suction. [0003] Patent CN10743...
