Description
Technical field:
The present invention relates to a kind of assay method and device of tobacco stem carbonization degree, be specially adapted to the detection of the offal carbonization situation produced in batches, belong to technical field of tobacco processing.
Background technology:
In raw tobacco material, offal account for leaf heavy 25% ~ 35%, the contradiction that effective utilization of offal can not only affect the production cost of cigarette, part solves raw tobacco material, and be effectively regulate one of fume indication, the important means promoting cigarette product quality.The emphasis that stem is the research of each tobacco enterprise is produced at present by adding thermal expansion.After heating expansion process, along with the loss of moisture in process, often there is carbonization phenomenon, after offal carbonization, great negative effect can be brought to the suction quality of cigarette in offal.The carbonization phenomenon of current offal there is no special detection method, and agricultural product carbonization phenomenon detects mainly chemical method at present, and instrument is more expensive, needs to consume reagent, and detection time is longer, have impact on the improvement of offal production technology and the innovation of job operation.Research shows, it is extremely remarkable that the carbonization phenomenon of offal and water percentage close, and the offal water percentage of non-carbonization and colour index to close be extremely significantly, the offal colour index after carbonization does not then change along with water percentage.This provides approach for utilizing offal colour index to characterize carbonizing degree.
Summary of the invention:
The object of the invention is to the deficiency overcoming prior art, and a kind of assay method and device thereof of tobacco stem carbonization degree are provided.
The concrete steps of the detection method of tobacco stem carbonization degree of the present invention are as follows:
A. according to the method for testing of CIE 1976 color space specification, measure colour index and the moisture of non-carbonization offal sample offal, get more than 20 non-carbonization offal samples, 50g offal grinds got by each sample, and sieve gets 30-60 order part; Take 1g offal powder and put into injector, by colour recognition brightness value L*, chromaticity index a*, b*, chroma C*, hue angle h* and moisture content determining device (6) measure its colour index and moisture; With atomizing humidifier (7) humidification offal powder, and through vibrating device (8) vibration balancing 5 minutes, again measure its colour index and moisture; In like manner, get carbonization offal sample, measure colour index before and after its humidification and moisture with said method; Data processor (5) records above data and sets up the mathematical model of offal powder colour index and moisture;
B. adopt the method identical with step a to the colour index before and after offal sample humidification and determination of moisture, data processor (5) provides tobacco stem carbonization degree numerical value and is presented at LCDs (3);
C. the tobacco stem carbonization degree numerical value in the tobacco stem carbonization degree numerical value obtained by step b and step a model is compared, and synthetic determination goes out the carbonizing degree of offal.
For the device of the assay method of tobacco stem carbonization degree, be made up of cabinet (1), injector (2), LCDs (3), control knob (4), data processor (5), colour recognition and moisture content determining device (6), atomizing humidifier (7), vibrating device (8), case lid (9); Wherein: injector (2), LCDs (3), control knob (4) are positioned on the panel of cabinet (1) dead ahead; Data processor (5), colour recognition and moisture content determining device (6), atomizing humidifier (7), vibrating device (8) are all fixed in cabinet (1); Cabinet (1) is provided with the data line interface and power supply that connect computer.Each parts in device are that market is bought.
The invention has the advantages that: the method can detect the carbonizing degree after offal heat treatment fast, apparatus structure is simple, and for ease of maintenaince and safeguard, economic input is less, is applicable to the research of offal processing experiment and quality testing.
