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
Reproduce stem as a kind of novel tobacco product, production process be by offal after chopping, extraction, drying
Blank stem is obtained, the backfill of backfill liquid component, drying are then carried out to it, backfills liquid by the extraction of smashed tobacco powder fragment, concentration, then
Corresponding tobacco aromaticss essence is added to be made.
By reproducing stem research and development of products, stem aesthetic quality can be significantly promoted, increase makes in cigarette composition
Dosage, reduces tobacco leaf consumption, and reconstruction stem application prospect is also more and more wide.On the one hand, reconstruction stem is compared to traditional stem
Have the characteristics that Filling power is high, miscellaneous gas is light, tobacco this perfume foot；On the other hand, backfilling the setting of backfill feed liquid in process can weigh
It is new to assign the adjustable controllable aesthetic quality of reconstruction stem, chemical constituent.Reconstruction stem has product in terms of improving cigarette product quality
Pole meaning.
Reconstruction stem backfill rate refers to the percentage that backfill over dry substance weight accounts for reconstruction stem over dry substance weight.Wherein,
Reconstruction stem is will backfill liquid and be backfilled to blank stem to be made after drying again, therefore, backfills exhausted dry substance mixture=reconstruction and obstructs
Silk oven dry weight-is by backfill blank stem over dry substance weight.
Since reconstruction stem production line is Sequential Production, can not be determined by the weight of backfill blank stem, therefore, nothing
Method fast and effectively measures the backfill rate that stem product is reproduced on production line using defined formula.
At present reconstruction stem backfill rate theory assay method be extraction weighing method, this method cardinal principle be by measure at
The recovery rate of product stem reflects its backfill rate, but following factor can have an impact measurement result：1, it is carried in continuous mode
The substance that takes out is simultaneously non-fully consistent with backfill component, it is also possible to including the contained water soluble ingredient of blank stem itself； 2、
Due to the limitation of extraction, in continuous mode, the backfill component of reconstruction stem also differs surely extracts completely.Therefore, it reproduces
The recovery rate of stem can not accurately reflect its backfill rate.
In conclusion now needing to work out a kind of assay method of reconstruction stem product backfill rate, easily and accurately to survey
Surely the backfill rate of stem is reproduced.
