Abstract
The present invention provides a kind of beating and double roasting blade construction range of needs measuring method based on conversion equation of transfer, initially set up the transfer equation of X and Y in piece cigarette cut tobacco drying, with baking silk -- the equation of transfer of flavoring Y and Z, then according to the Cut tobacco standard of predecessor, X is found out in conjunction with above-mentioned two equation, the present invention is from the quality of cigarette or the angle of stability, demanding criteria according to specific Cut tobacco, the transformational relation between blade construction and Cut tobacco is built, specifies the range of needs and control direction of blade construction.
Description
Technical field
The present invention relates to a kind of beating and double roasting blade construction range of needs measuring methods based on conversion equation of transfer, belong to
Tobacco leaf production field.
Background technology
Cigarette leaves and tobacco structure is usually according to YC/T178-2003"The assay method of pipe tobacco whole cut rate, filament broken rate"It is surveyed
Amount, Cut tobacco cover long filament, middle silk, short silk, broken silk, to the physical index such as substance of cigarette whether the stabilization of Cut tobacco,
The stability of the such as open resistance to suction of fume indication has large effect.It is compared and is found by test data, generally pass through technique road
The change for the Cut tobacco that the variation in the variation different place of production, raw material of the Cut tobacco that diameter is brought with changes in process parameters is brought
Change is much smaller, therefore to the control of raw material blade construction, can influence the stability of Cut tobacco and the flue gas mass of cigarette.
At this stage, the range of needs of cigarette industry research beating and double roasting blade construction still belongs to blank, and is mainly grinding
In the relationship for studying carefully blade construction and Cut tobacco, there are mainly two types of thinkings at present, on the one hand mainly pass through Cut tobacco and leaf
Chip architecture establishes regression equation.If the Jiang Xuebin of Hubei Zhong Yan Wuhan Cigarette-Making Factory is in volume 46 the 1st of Jiangsu's agriculture science 2018
" correlativity of blade construction and Cut tobacco " that phase delivers.Provide the phase of blade construction and Cut tobacco for the first time in paper
Pass relationship and regression equation.Analysis method this first discusses the correlativity between blade construction and Cut tobacco for the first time.
But the conversion of blade construction and Cut tobacco is multidimensional to multidimensional during actual, is exactly a kind of blade construction in brief
A variety of cut tobaccos can be converted into, so regression equation of unitary is difficult the variation for explaining actual blade construction to Cut tobacco
Process.In addition it is related to the solution of complicated inequation group by the anti-leaf-pushing plate structure of Cut tobacco, so paper also is difficult to
And the distribution of blade construction is not provided yet.
Still further aspect, by remaining Na of Shanghai Tobacco Group Co., Ltd. etc. in Light Engineering Institutes Of Zhengzhou's journal 2013
The 3rd phase of volume 28 year June " in the relational model research of blade construction and Cut tobacco " establish the area and cut tobacco of blade
Relationship between the characteristic size of structure.Due to being difficult inspection under the blade construction detection device and standard in existing beating and double roasting
Measure the area of blade, and the relationship between blade area and blade construction is complex is difficult to unification, therefore paper does not have still
Have and clearly answers under existing beating and double roasting blade construction detection architecture, the clear transformational relation of Cut tobacco and blade construction,
And the range of needs of the beating and double roasting blade construction based on this.
For a long time, economy is based on from the point of view of tobacco leaf usability, and in beating and double roasting link, entire cigarette industry exists
Beating and double roasting field is all wanted to maintain higher Percentage of large and middle size strips as far as possible, the reason is that in order to keep higher Percentage of large and middle size strips
Process, certain technological measure will certainly be taken to reduce, and making for tobacco leaf is broken, and offal is seldom, and the utilization rate of tobacco leaf will improve,
The waste of tobacco leaf economic resources is avoided to a certain extent.It is bright if in beating and double roasting blade construction standard YCT 146-2010 tables 3
It really proposes, the first-class Yan > of Percentage of large and middle size strips of blade construction;83%, Zhong Dengyan >81%, inferior Yan >77%.
Invention content
How from the quality of cigarette or the angle of stability, according to the demanding criteria of specific Cut tobacco, structure
The transformational relation between blade construction and Cut tobacco is built, it is this clearly to derive the range of needs of blade construction and control direction
The main purpose of patent.
Present invention employs following technical solutions:
