Description
Technical Field
The invention belongs to the technical field of cigarette manufacturing, and particularly relates to a method for measuring backfill uniformity of reconstituted cut stem feed liquid.
Background
The reconstituted cut stems are novel tobacco stem products, are raw materials for making cigarettes, and are characterized in that water-soluble components which are not beneficial to smoking taste and are contained in the tobacco stems are washed away in the production process, more feed liquid for improving the taste is added, the reconstituted cut stems are added into cut tobacco, the smoking taste of the tobacco can be adjusted, the reconstituted cut stems have better sensory quality, the tar and harm can be reduced, the reconstituted cut stems have higher filling capacity and stronger combustion capacity like common cut stems, and the reconstituted cut stems have better service performance in the production of the cigarettes.
The production process of the reconstituted cut stems comprises the following steps: the method mainly comprises the steps of tobacco stem moisture regaining, stem storage, stem pressing, stem cutting, extraction, drying, backfilling and drying, the difference of the manufacturing process of the reconstituted stem shreds and the manufacturing process of the common stem shreds is mainly reflected in the two processes of extraction and backfilling of the stem shreds, the process of manufacturing the common stem shreds is not provided with an extraction process, the feeding process of producing the common stem shreds is similar to the backfilling process of producing the reconstituted stem shreds, and the difference is that the backfilling amount of the reconstituted stem shred material liquid is far larger than that of the common stem shreds. The extraction method comprises soaking the cut stems in flowing clear water for a certain time to dissolve the water-soluble components in the cut stems in water. The material liquid applied in the backfilling process is mainly water-soluble components extracted from tobacco fragments and tobacco powder, and aims to improve the chemical quality of the cut stems and improve the sensory quality of the cut stems. The stem shreds are provided with developed plant fiber bundles, dense gaps exist among the fiber bundles, when the stem shreds are extracted, the gaps among the fiber bundles are further increased, and the gaps among the fiber bundles are expanded due to high temperature after drying, so that a large amount of feed liquid (tens of times of the feed liquid of the common stem shreds) can be applied to the reconstructed stem shreds in a backfilling process, and the sensory quality of the stem shreds is improved. The process has important influence on sensory quality, suction taste and stability of smoke indexes of the reconstituted cut stems, after the feed liquid backfilling process, the consistency degree of the weight of the feed liquid contained in the cut stems per unit weight is determined, and the backfilling uniformity degree of the feed liquid has a decisive effect on the stability and consistency of product quality, so that the research on the backfilling uniformity of the reconstituted cut stems has important significance on the quality control of the reconstituted cut stem products.
The closest existing method for measuring the backfill uniformity of the reconstituted cut stems is a method provided by YC/T353-2010 (determination of cigarette feeding uniformity), 1, 2-propylene glycol is required to be added as a marker, specifically, the method of YC/T353-2010 is to add 1, 2-propylene glycol as a marker in feed liquid in a feeding process, take 30 samples after the feeding process, measure the percentage content of 1, 2-propylene glycol, calculate a uniformity coefficient by using the measured percentage content of 1, 2-propylene glycol in the 30 samples, and evaluate the feeding uniformity by using the calculated uniformity coefficient. However, 1, 2-propanediol is not an essential component of the feed liquid, is an exogenous marker, increases the measurement cost when the addition amount is large, and may also cause adverse effects on the pumping quality of the product, the addition amount of the marker 1, 2-propanediol is generally small in the measurement, and errors are likely to occur when the percentage content is measured, so that 30 samples need to be taken for measurement in the method to meet the requirement of calculating the uniformity coefficient, and the method is complex to operate, large in workload and high in measurement cost.

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the production process of the reconstituted cut stems, the percentage content of total plant alkaloid of the cut stems after extraction and drying is extremely low (less than 0.08%), and the percentage content of the total plant alkaloid of the cut stems after backfilling is more than 1.2%, namely more than 93% of the total plant alkaloid contained in the reconstituted cut stems after backfilling comes from the feed liquid applied in the backfilling process, so that the consistency of the weight of the feed liquid contained in the reconstituted cut stems per unit weight after the feed liquid is backfilled can be regarded as the backfill uniformity of the feed liquid. Based on the above principle, the embodiment of the method for determining the backfill uniformity of the reconstituted cut stem material liquid provided by the present application is shown in fig. 1, which is a schematic diagram of the method for determining the backfill uniformity of the reconstituted cut stem material liquid provided by the present application, and the method comprises the following steps:

it should be noted that the preset time interval may be, but not limited to, 30 seconds to 120 seconds, the obtaining mode may be extraction, and it is to be ensured that the cut stems at all positions on the cross section of the cut stem flow are obtained, so that the measurement of the uniformity is more accurate, the weight of each obtained reconstructed cut stem sample may be, but not limited to, 40 grams to 50 grams, which can ensure that the cut stems at all positions of the cross section are obtained, and the number of the parts n of the sample is at least 10, that is, 11, 12 or more, depending on the actual measurement requirement, each sample is placed into a corresponding sealed container, which greatly reduces the number of samples, reduces the number of measurement steps, and also reduces the measurement cost compared with the scheme of selecting at least 30 samples in the prior art.
S2: drying each reconstructed cut stem sample;
specifically, the sealed container containing the reconstituted cut stem sample can be placed into an oven, and each reconstituted cut stem sample can be dried at a temperature not higher than 40 ℃ without limitation until the sample can be ground by fingers.
S3: respectively grinding and uniformly mixing the reconstructed cut stem samples to form a plurality of powder samples;
specifically, the dried cut stems are taken out of the oven and immediately ground, and the following methods can be adopted, but are not limited to: the first continuous grinding time can be no more than 2 minutes, then the reconstituted cut stem sample is sieved, the sieve can be but is not limited to a 40-mesh sieve, then the unsieved reconstituted cut stem sample is ground for the second time, the sieved powder is immediately filled into a clean wide-mouth bottle and sealed, and the wide-mouth bottle is fully shaken and uniformly mixed.
S4: determining the percentage of the preset parameter of each powder sample, wherein the percentage of the preset parameter of the ith powder sample is miThe average value of the preset parameters of the n powder samples is M;
it should be noted that the preset parameter may be any parameter with a low percentage content or even no percentage content before backfill feeding and a greatly increased percentage content after backfill feeding, which means that the improvement of the preset parameter is almost completely from the feed liquid backfill flow, and the preset parameter must be a conventional component of the backfill feed liquid and cannot be added subsequently, so that the uniformity of the feed liquid backfill effect can be represented, and of course, the preset parameter may have various types, and may not be limited to the total plant alkaloid percentage content.
S5: using formulas
And calculating a backfill uniformity coefficient CU.
It should be noted that the calculation result of the backfill uniformity coefficient CU needs to be accurate to 0.0001, and by using the formula, the measurement accuracy is better, so that the method is suitable for measuring the backfill uniformity of the feed liquid in the production process and evaluating the quality stability of other processes after the feed liquid is backfilled, such as the extrusion homogenization process.
Therefore, the method is applicable to the reconstructed cut stems, which is different from the prior art that only tobacco leaves are used, so that the accuracy of measuring and evaluating the backfill uniformity of the reconstructed cut stem material liquid is higher.
According to the above description, in the embodiment of the method for determining the backfilling uniformity of the reconstituted cut stem material liquid provided by the application, the cut stems are obtained from the outlet of the backfilling process of the reconstituted cut stem material liquid at the preset time interval, so that n reconstituted cut stem samples are obtained; drying each reconstructed cut stem sample; respectively grinding and uniformly mixing the reconstructed cut stem samples to form a plurality of powder samples; finally, the percentage content of the preset parameter of each powder sample is determined, and the percentage content of the preset parameter of the ith powder sample is miThe average value of the preset parameters of the n powder samples is M; and the backfill uniformity coefficient CU is calculated by utilizing the formula, so that the exogenous marker is not added like the prior art, the measurement can be completed only by using the conventional components of the backfill material liquid, the quality of a final product is not adversely affected, the number of measurement steps is reduced after the step of adding the exogenous marker is reduced, the measurement convenience is improved, and the measurement cost is reduced.
In a specific embodiment of the method for determining the backfill uniformity of the reconstituted cut stem material liquid, the preset parameter can be the percentage content of total plant alkaloid or the percentage content of total sugar. It should be noted that the most common way is to use the total plant alkaloid content to determine the backfill uniformity of the feed liquid, but there are limitations in some cases, for example, when the total plant alkaloid content after backfill is low, for example, not more than 0.4%, the determination of the backfill uniformity by using the total plant alkaloid content is not suitable, and after that, the total plant alkaloid content before and after the backfill of the feed liquid is not changed greatly, at this time, the total sugar content can be determined, and the same effect of measuring the backfill uniformity of the feed liquid can be obtained.
In another specific embodiment of the method for determining the backfill uniformity of the reconstituted cut stem material liquid, the preset parameter may be nicotine percentage or reducing sugar percentage. Note that, the nicotine is contained in the total plant alkaloid, the backfill uniformity of the feed liquid can be measured by the percentage content of the nicotine alone, and the backfill uniformity of the feed liquid can be measured by the reducing sugar alone.
