Technical Field

The invention belongs to the technical field of primary flue-cured tobacco processing, and particularly relates to a method for removing impurities, upgrading and slitting tobacco leaves.

Background

In the same tobacco leaf, due to the existence of the included angle between the stem and the leaf, the difference between the illumination conditions and the effective accumulated temperature in different sections (leaf margin and leaf) of the same tobacco leaf is caused, which inevitably causes different degrees of metabolism, conversion and accumulation of substances in different sections (leaf margin and leaf) of the tobacco leaf, so that the different sections (leaf margin and leaf) of the same tobacco leaf have obvious difference in the aspects of conventional chemical indexes, sensory quality, tissue structure, mechanical processing performance and the like. In the production process of tobacco leaves, scorched spots are concentrated on the leaf margin part of the tobacco leaves and the content is insufficient, which can cause the scorched gas, the wood gas and other miscellaneous gases in the leaf margin section to be prominent.

The existing tobacco leaf cutting technology cuts tobacco leaves mainly according to the quality difference among the leaf tips, leaves and leaf bases of the tobacco leaves, and the cutting method does not carefully study the main section generated by the miscellaneous gas of the tobacco leaves and cannot effectively remove the miscellaneous gas of the tobacco leaves. The existing three-section type cutting method usually only separates the leaf base (which is part of the leaf margin of the method) with relatively poor quality, and a large number of segments generating miscellaneous gas are mixed in good tobacco leaves for use, so that the expression of the quality of the whole tobacco leaves is influenced. Therefore, it is necessary to study the quality difference of tobacco leaves in different sections and control the use of tobacco leaves in the main section where miscellaneous gas is generated, thereby improving the comprehensive utilization value and industrial availability of the tobacco leaves.

Disclosure of Invention

Based on the problems in the prior art, the invention aims to provide a method for removing, upgrading and slitting tobacco leaves, so that the impurity gas of the tobacco leaves can be effectively reduced, the quality of the tobacco leaves is improved, and the use value of the tobacco leaves is improved.

In order to realize the purpose of the invention, the following technical scheme is adopted:

a method for removing impurities, upgrading and slitting tobacco leaves is characterized by comprising the following steps: the method comprises the steps of firstly cutting the tobacco leaves to divide the tobacco leaves into two parts, namely a leaf edge part and a leaf middle part, removing the leaf edge part, and then cutting the remaining leaf middle part into cut tobaccos and applying the cut tobaccos.

Further, the shearing is carried out at the position of 0.5-2.5cm from the leaf edge to the inner part of the leaf.

Aiming at the fact that the quality difference of different sections of the same piece of tobacco leaves is large, the invention provides a novel tobacco leaf slitting treatment mode, the leaf edges and the middle parts of the tobacco leaves are separated, the effectiveness of a separation thought is verified through measuring the conventional chemical components and the sensory quality of the tobacco leaves, and the parts with poor quality are separated, so that the miscellaneous gas of the tobacco leaves is effectively reduced, the quality of the tobacco leaves is improved, and the use value of the tobacco leaves is improved. The method comprises the following specific steps:

(1) selecting 20 tobacco leaves in tobacco packets of the same production area, the same variety, the same grade and the same batch, and respectively measuring the length and the width of each tobacco leaf, wherein the difference of the leaf length of each tobacco leaf is less than or equal to 3cm, and the difference of the leaf width of each tobacco leaf is less than or equal to 2 cm;

(2) 5 pieces of tobacco leaves in the selected 20 pieces of tobacco leaves are not cut, namely, the whole tobacco leaves are cut; the rest 15 tobacco leaves to be cut are stacked together in order, and are cut at the position of 0.5-2.5cm from the leaf margin to the inner part of the leaf, so that the tobacco leaves are divided into two parts, namely a leaf margin part and a leaf middle part; collecting leaf margin, leaf and whole leaf, separating main vein, cutting into tobacco shreds respectively, and mixing; finally, dividing the 3 parts of cut tobacco into 2 parts respectively, wherein one part is used for measuring the content of conventional chemical components, and the other part is used for evaluating sensory quality;

(3) taking the conventional chemical component indexes and the total sensory quality scores as evaluation factors, carrying out statistical analysis, and comparing quality differences;

(4) according to the industrial evaluation index, after the section with poor quality is separated, the quality performance of the rest part is better, and the application prospect is better.

The analysis result shows that the conventional chemical components and the sensory quality performance are sorted from high to low into leaves, whole leaves and leaf edges, so that the leaf edge part of the tobacco leaves can be separated, the miscellaneous gas of the tobacco leaves is reduced, and the quality of the tobacco leaves is improved.

Compared with the prior art, the invention has the beneficial effects that:

the invention cuts the tobacco leaves according to the quality difference between the leaf margins and the leaves of the tobacco leaves, and after the leaf margins are separated at proper sites, the quality of the sections in the tobacco leaves is obviously improved and more coordinated, miscellaneous qi (mainly scorched qi) is obviously lightened, the taste is obviously improved, and the texture is obviously improved. By the aid of the cutting method, miscellaneous gas of the tobacco leaves can be effectively reduced, the quality of the tobacco leaves is improved, and the use value of the tobacco leaves is improved. The method is simple and easy to implement, low in cost and good in application prospect.
