Description
Technical field
The invention belongs to reproduce stem production technical field, and in particular to a kind of measurement side of reconstruction stem product backfill rate
Method.
Background technology
Backfill liquid is the main carrier for reproducing stem soluble component and fragrance component, and the height of backfill rate directly affects
Chemical composition, physical index, fume indication and the suction quality for reproducing stem are produced in reconstruction cut stem production process technology
One of manufacturing capacity index the most main.
Reconstruction stem backfill rate is the percentage for reproducing stem backfill liquid over dry material mass and accounting for reconstruction stem absolute dry mass
Ratio.
But the backfill rate of reconstruction stem is estimated by online production at present, i.e., is led to by the blank stem in backfilling process
Excessive and backfill liquid feeding quantity is calculated.And actual backfill effect can not be detected directly.Therefore it needs to work out one kind
The assay method for reproducing stem product backfill rate, easily and accurately to measure the backfill rate of reconstruction stem.
Invention content
The object of the present invention is to provide a kind of assay method of reconstruction stem product backfill rate, having can be convenient accurate
Ground measures the advantages of backfill rate of reconstruction stem.
The present invention provides the following technical solutions：
A kind of assay method of reconstruction stem product backfill rate, includes the following steps：
(1) the blank stem sample before a certain amount of backfill and the stem sample after backfill is first taken to be respectively placed in close in hermetic bag
Sample is uniformly mixed by envelope in hermetic bag, then measures the blank stem sample before backfill, stem sample after backfill contains
Water rate is respectively M and M', and the blank stem sample before the backfill is not returning before filling out charger reconstruction stem production line last time
The stem filled out, the stem sample after the backfill are the stem reproduced after stem production line backfill charger；
(2) a certain amount of backfill liquid sample is taken, the mass concentration for measuring backfill liquid sample is S；Mass concentration S is over dry object
Matter quality accounts for the percent ratio of backfill liquid quality；
(3) reconstruction stem product backfill rate C, calculation formula are calculated
The derivation method that reconstruction stem product backfill rate measures in step (3) is as follows：
If the quality of the unit blank stem sample before backfill is A, then moisture in the unit blank stem sample before backfilling
Quality is A × M, unit blank stem absolute dry mass A × (1-M)；
The backfill liquid quality of backfilling process consumption is B, then the over dry material mass for consuming backfill liquid is B × S, consumption backfill
The biodiversity contained in liquid is B × (1-S)；
By backfill, over dry substance and moisture in the backfill liquid of consumption are all absorbed by blank stem, therefore are obstructed after backfilling
Moisture in silk sample：
Stem product backfill rate is reproduced after then backfilling：
C is backfill rate, unit % in formula；M is the moisture content of the blank stem before backfill, unit %；S is backfill
The mass concentration of liquid sample, unit %；M' is the moisture content of the stem sample after backfill, unit %.
Preferably, the stem sample after the backfill in the step (1) is that reconstruction stem production line backfills charger
Afterwards, by squeezing, the stem that liquid has been evenly distributed is backfilled.
Preferably, the blank stem sample before the backfill in the step (1) and the stem sample after the backfill
Sample point close to backfill charger.
Preferably, the blank stem sample before the backfill in the step (1) and the stem sample after the backfill
It is placed in hermetic bag to seal and balance 10-60min after mixing and measures moisture content again.
Preferably, after measuring the blank stem before the backfill, the backfill by moisture detector in the step (1)
Stem sample moisture content, the mass concentration of the backfill liquid sample is measured in the step (2) by concentration detector.
The quality of blank stem before being backfilled in the present invention, the moisture content of the stem sample after backfill and backfill liquid sample is dense
Degree, which can be also placed in measuring cup by manually weighing the sample of a certain amount of acquirement, to be dried with baking oven under 105 DEG C of ± 2 DEG C of temperature environments
The moisture being calculated in either sample of weighing after doing to constant weight can also be used online or offline inspection equipment and directly obtain.
Compared with prior art, the beneficial effects of the invention are as follows：
1, the assay method of a kind of reconstruction stem product backfill rate provided by the invention, has simple operation, result accurate
Degree is higher, is suitable for reconstruction stem production line on-line checking and laboratory technique research, can objectively indicate reconstruction stem production
Product backfill rate.
2, the stem sample after the backfill in heretofore described step (1) is reconstruction stem production line backfill charging
After machine, by squeezing, the stem that backfill liquid has been evenly distributed is reduced in the stem sample after backfill because there is the distribution of backfill liquid not
Uniformly influence the accuracy of testing result.
3, the blank stem sample before the backfill in heretofore described step (1) and the stem sample after the backfill
The sample point of product avoids the blank stem sample before the backfill before entering charger and enters charger close to backfill charger
Stem sample after backfill afterwards causes testing result big error occur because there is moisture loss.
4, the blank stem sample before the backfill in heretofore described step (1) and the stem sample after the backfill
Product are placed in hermetic bag to seal and balance 10-60min after mixing measures moisture content again, can make the sky before backfill in this way
White stem sample is more uniform with the moisture distribution in the stem sample after backfill, improves it and detects the accuracy of moisture content.
5, in heretofore described step (1) by moisture detector measure the blank stem before the backfill, described time
The moisture content of stem sample after filling out, the quality for measuring the backfill liquid sample in the step (2) by concentration detector are dense
Degree has the advantages that simple operation and accurate.
