Description
Technical field
The present invention relates to tobacco purchase classification field, more specifically, relate to the continuous detection apparatus of oil content in a kind of plant leaf blade.
Background technology
When tobacco purchase stands in purchase tobacco, because land for growing field crops tobacco leaves property is different, after modulation, quality is not identical yet, if quality mixes, use value must reduce, and causes the wasting of resources, and economic benefit reduces.Former cigarette is through repeatedly processing, and scientific formula just can be produced and meet that consumer requires, that style is different cigarette, and scientific formula completes on the basis of tobacco leaf grading, if high-grade Virginian-type cigarette is based on middle leaf.Tobacco leaf grading is conducive to transferring tobacco grower and produces the enthusiasm of sound tobacco, increases the income of tobacco grower, with time stage and price also for tobacco grower specifies the direction of leaf tobacco production.Reasonable classification is conducive to carrying out and reasonably develops the exploitation inferior quality tobacco leaf of tobacco leaf secondary product and tobacco leaf secondary product.Therefore, tobacco leaf grading during tobacco purchase has great importance.
GB2635-1992 gives the standard of cured tobacco leaf classification, and be divided into 42 grades, the parameter that tobacco leaf grading relates to is more, comprises all many-sides such as position, color, oil content, colourity, width, length, residual wound and breakage.Oil content is the important parameter of tobacco leaf grading, oil content and quality of tobacco closely related, the height of the number reflection quality of tobacco of oil content.The judgement of oil content class, the directly judgement of impact to tobacco leaf degree.In existing flue-cured tobacco national standard to the definition of oil content be: " oil content refers to the soft semiliquid of the one that contains in tobacco leaf or liquid substance, according to sensory feel, be divided into many, have, slightly, lack four class ".In general, oil content is many, and quality of tobacco factor is good; Oil content is few, and quality of tobacco is poor.
When current tobacco purchase stands in purchase tobacco leaf, oil content qualification and classification can only be carried out to tobacco leaf by the classification personnel of specialty, thus purchase with different prices, but artificial qualification result subjective factor is strong, the dispute that classification produces is larger, and the speed of manual grading skill is slow, efficiency is low, badly influences the progress of tobacco purchase.
Summary of the invention
The present invention, for overcoming the defect that manual grading skill result subjective factor is strong, classification efficiency is low described in above-mentioned prior art, provides the continuous detection apparatus of oil content in the objective plant leaf blade of a kind of low cost, classification results.
