Problems solved by technology

[0003] The existing tobacco leaf cutting technology is mainly based on the quality difference between the tip, leaf and leaf base of the tobacco leaf. This cutting method has not carried out detailed research on the main section of the tobacco leaf miscellaneous gas generation, and it is impossible to analyze the tobacco leaf miscellaneous gas. effective removal of gas
The existing three-stage cutting method often only separates the relatively poor-quality leaf base (which is also a part of the leaf edge of this method), and a large number of sections that generate miscellaneous gas are mixed with good tobacco leaves for use, affecting the overall tobacco leaves. expression of quality

Embodiment 1

[0019] Select 20 pieces of B2F grade tobacco leaves of Yun 87 variety. Through measurement, the length of the tobacco leaves is between 59-62cm, and the width is between 17-19cm. figure 1 Schematic diagram of tobacco leaf cutting. 15 tobacco leaf samples were cut into two parts at a position 1.0-2.5 cm inward from the edge of the leaf, that is, the leaf edge and the middle part of the leaf, and the remaining 5 tobacco leaves were not cut, that is, the whole leaf. The leaf edge, leaf and whole leaf samples were cut into shredded tobacco and mixed evenly, and divided into two parts, one for routine chemical composition determination of tobacco leaves, and one for tobacco leaf sensory quality identification. According to the method YC / T160-2002, YC / T159-2002, YC / T161-2002, YC / T162-2002 and YC / T162-2002 stipulated in the industry standard, determine the sample nicotine, total sugar, reducing sugar, total nitrogen, potassium and chlorine content.

[0027] Select 20 pieces of tobacco leaves of C3F grade of Yun 87 variety. Through measurement, the length of the tobacco leaves is between 63-66cm, and the width is between 20-22cm. figure 1 Schematic diagram of cutting tobacco leaves. 15 tobacco leaf samples were cut into two parts at a position 0.5-2.0 cm inward from the edge of the leaf, that is, the leaf edge and the middle part of the leaf, and the remaining 5 tobacco leaves were not cut, that is, the whole leaf. The leaf edge, leaf and whole leaf samples were cut into shredded tobacco and mixed evenly, and divided into two parts, one for routine chemical composition determination of tobacco leaves, and one for tobacco leaf sensory quality identification. According to the method YC / T160-2002, YC / T159-2002, YC / T161-2002, YC / T162-2002 and YC / T162-2002 stipulated in the industry standard, determine the sample nicotine, total sugar, reducing sugar, total nitrogen, potassium and chlorine content.

Abstract

The invention discloses a tobacco leaf impurity removing, quality improving and slitting method which comprises the following steps: tobacco leaves are sheared firstly, the tobacco leaves are dividedinto two parts, namely the leaf edge part and the leaf middle part, the leaf edge part is removed, and then the remaining leaf middle part is cut into tobacco shreds to be applied. By means of the slitting method, offensive odor of the tobacco leaves can be effectively reduced, the tobacco leaf quality is improved, and the tobacco leaf use value is improved.

Description

technical field [0001] The invention belongs to the technical field of raw-cured tobacco leaf processing, and in particular relates to a tobacco leaf cutting method for removing impurities and improving quality. Background technique [0002] For the same tobacco leaf, due to the existence of the angle between the stem and the leaf, the difference in light conditions and effective accumulated temperature in different sections (edge ​​and middle) of the same tobacco leaf will inevitably result in different sections of the tobacco leaf (edge ​​and middle leaf). ) have different degrees of metabolism, transformation and accumulation of substances contained in the same tobacco leaf, resulting in obvious differences in conventional chemical indicators, sensory quality, tissue structure and even mechanical processing performance in different sections (leaf edge and leaf middle) of the same tobacco leaf. difference. In the process of tobacco leaf production, the leaf margins of tob...
