Description
Technical field
The present invention is suitable for careless cigarette industrial system, and specially a kind of tobacco aromaticss prepare accuracy method for quickly detecting.
Background technique
In tobacco industry production, tobacco aromaticss are indispensable aromatizing agents, are used for tobacco leaf surface spray flavoring, mention
High tobacco leaf fragrance characteristic reduces blade grade difference.Blade charging is the important production process of tobacco industry.
The preparation of essence spice for cigarette is to be weighed to modulate by operator according to formula rate by various of monomer perfume base
At following mistake easily occurs in allocation process: 1, monomer is replaced;2, monomer weighing mistake;3, stirring is uneven.The above mistake or behaviour
Making mistakes all will lead to feed liquid and does not meet manufacturing technique requirent, if such feed liquid, which is applied on tobacco leaf or pipe tobacco, will lead to product
Taste variation is inhaled, the suction of product sensory product is unqualified, eventually leads to great quality accident, damages to image product, must so having
Gate of the quality monitoring is maintained strict control in production link, improve live control ability.
The method of inspection that existing general essence spice for cigarette in the industry prepares accuracy is refractometry, and instrument is Abbe
Refractometer determines whether feed liquid process for preparation is accurate by the refractive index of soluble solid in measurement feed liquid.But this
Requirement of the method by the environmental factors such as measurement environment temperature, pressure and peopleware, so be not suitable for field quick detection,
It is also not suitable for layman's use.Such method is limited to more for production, and not being able to satisfy site technique person's inspection makes
With.
Since tobacco aromaticss are a kind of composite fluid feed liquids, it includes a variety of different material bases to require to press according to factory formula
Ratio is blent, and the free radical in every kind of material base is different, and the pH value presented is different, the pH of feed liquid after material base mixes in proportion
Value has specificity.This provides new angle for the inspection that essence spice for cigarette prepares accuracy.
In general, there are two types of methods for the measurement of pH value: chemical sensor method and artificial colorimetric ocular estimate.
First method is commonly used in the scientific research test high to required precision, can accurately be quickly obtained high-precision
The pH value of degree, and in most cases the considerations of for cost and the particularity of production scene, is just sufficiently achieved with colorimetric method
Solution ph is measured in most of industrial productions in the requirement of precision aspect.Usual colorimetric ocular estimate is to be carried out by naked eyes to color
Matching identification is compared to judge to presentation color and with reference colour library current molten by certain medium such as pH test paper
Liquid pH value.But there is also apparent drawbacks for this method, such as compare the light source difference of environment, lack objective appraisal mark
The presence of the factors such as standard, judging result can generate subjective meaning and sentence or judge by accident, and then influence use and the product of result
Judging result.
In view of the above circumstances, it if carrying out essence spice for cigarette using digital image processing techniques prepares Test of accuracy, mentions
High pH measurement accuracy will overcome the shortcomings of that artificial vision identifies, this has actual industrial production significantly existing
Sincere justice.
Summary of the invention
In view of the above-mentioned problems, the present invention provides a kind of tobacco aromaticss to prepare accuracy method for quickly detecting.The present invention according to
The chromogenic reaction principle of support pH test paper improves tobacco aromaticss with machine vision technique (HSV algorithm) to Color Quantization by Color
The precision for preparing accuracy rapid detection method, solves the problems, such as that production scene feed liquid can not be detected quickly.
The technical solution adopted by the present invention to solve the technical problems are as follows:

Difference takes its pH test paper color development image information according to franchise preparation liquid, calculates H value, feed liquid H value value range can be obtained;
Step 3 establishes standard feed liquid H Value Data library;
Step 4, production sample and calculate H value;
Step 5 is sentenced different according to CD method;
Step 6 is rechecked using SPC method.
As a further improvement of the above technical scheme, the present invention the following steps are included:
Step 1 acquires standard feed liquid test paper color development area image
Using factory formula as foundation, perfume monomer is required to carry out weighing preparation according to formula rate, weighing essence when preparation
Degree is 2 significant digits, and prepared feed liquid is sufficiently stirred and is warming up to 60 DEG C, picks feed liquid with glass bar, is placed in pH examination
On paper, color development area image is acquired with capture apparatus in 3s;
Step 2 carries out image quantization using HSV
The tone H, saturation degree S and the lightness V that acquire colour developing image are quantified, excluded by capture apparatus and ring
The S value and V value that border influences take tone H value to establish standard feed liquid comparison database, calculate each perfume monomer weight according to technological standards and permit
Difference takes its pH test paper color development image information according to franchise preparation liquid, calculates H value, feed liquid H value value range can be obtained;
Step 3 establishes standard feed liquid H Value Data library
The standard feed liquid H value that step 2 is calculated is established into comparison database according to the production trade mark, is carried out when to be used
It compares.
Step 4, production sample and calculate H value
Sample and colour developing are carried out according to step 1 method to prepared feed liquid by site technique personnel in production process
Area image acquisition, and feed liquid H value is calculated according to step 2 method, gained sample image information is deposited with production batch number name
Shelves.
Step 5 is sentenced different according to CD method;
According to CD method, i.e. Comparison Method, sample H value is compared with corresponding trade mark database value, if in database value
In range, then determine that feed liquid prepares qualification, meets technique and require can be used;If exceeding database value range, determine to expect
Liquid prepares unqualified, waiting reinspection.
Step 6 is rechecked using SPC method
Configured feed liquid to be rechecked is stirred, sampling in every 2 minutes is primary, takes altogether 30 times, and it is anti-to do colour developing to sample
H value should and be calculated, is determined using SPC method, can be used normally if reinspection is determined as normally;If reinspection is determined as different
Often, then feed liquid is done and scraps processing.
Bring beneficial effect of the present invention has:
The more original industry universal method of this method be more suitable production scene use, substantially increase quality control capability,
It has the advantage that
1, quick obtaining is as a result, greatly shorten the pattern detection time;2, inspection easy to carry, being suitble under the complex environment of scene
It surveys;3., the influence of not examined environment;4, personnel specialty competency profiling is low;5, micro using sample, it is (former to save feed liquid cost
Sampling amount >=100mL).
