Description

TECHNICAL FIELD

[0001] The present application relates to the field of tobacco preservation, in particular to a method for preparing a sample of tobacco for a cigar. BACKGROUND

[0002] A cigar is a special tobacco product, which is made of dried and fermented tobacco. It has the characteristics of strong strength, thick and full aroma, sweet and bitter taste, etc. It has less tar and nicotine than ordinary cigarettes, and is less harmful to the human body. It is deeply loved by consumers at home and abroad, and has great market potential. Cigars can be divided into cigar jackets, cigar wrappers and cigar cores. The cigar jacket is the clothes of the cigar, which not only has a typical cigar style, but also has high requirements for the appearance quality and intrinsic chemical quality of tobacco leaves. Generally, the domestic cigar jacket requires good leaf gloss, uniform color, strong tensile strength, good elasticity, appropriate size, wide leaf shape, slightly thin thickness, good integrity, fine and non-protruding veins, and consistent vein color and leaf tissue.

[0003] The quality of cigar jacket tobacco is extremely high. The color, maturity, identity, oil content, leaf structure, color, leaf size and shape, leaf surface state, mixed color, smoothness and damage characteristics of the tobacco leaf will all affect its quality. Therefore, the preservation environment of the tobacco leaf is crucial. In the prior art, large quantities of tobacco are generally preserved by stacking and sealing to reduce oxygen. For small quantities of tobacco, such as sample cigar jacket tobacco for display, kraft paper packaging is often used. This method has good durability, can withstand a certain weight and pressure, and is simple to operate, but still has many problems: (1) the tobacco leaf loses water quickly and is prone to dry cracking; (2) the waterproof and moisture-proof performance is poor, the shelf life is short, and the tobacco leaf is prone to moisture regain, mold and deterioration; (3) it cannot be transported over long distances and displayed multiple times. SUMMARY

[0004] In view of the above shortcomings of the prior art, the present application aims to provide a method for preparing a sample of cigar jacket tobacco for display. This method can reduce the damage rate of the leaf tip and leaf edge of the tobacco leaf, ensure the integrity of the cigar jacket tobacco, and retain aldehydes, alcohols, ketones, alkenes, esters and pyridines in the tobacco leaf. The prepared tobacco leaf can be preserved for a long time, recycled, transported conveniently and cost-effectively.

[0005] To achieve the above-mentioned purpose, the following technical solutions are used:

[0006] A method for preparing a sample of cigar jacket tobacco for display, comprising the following steps:

[0007] S1. Selecting cigar jacket tobacco leaves with good integrity and uniform color, cleaning the dirt on the surface of the tobacco leaves, and drying the tobacco leaves to a water content of not more than 20%;

[0008] S2, the tobacco leaf obtained in step S1 is spread flat and placed on the base plate;

[0009] S3, the tobacco leaf is completely covered with the elastic transparent film along the base plate, and the air between the elastic transparent film and the base plate is removed;

[0010] S4, the elastic transparent film and the tobacco leaf are heated at 30-35℃ for 3-6min, and then cooled;

[0011] S5, the base plate with the tobacco leaf obtained in step S4 is placed in the display box with the tobacco leaf side up, and a display sample of the tobacco leaf is obtained.

[0012] The tobacco leaf is placed on the base plate, and the elastic transparent film is used to cover the tobacco leaf to isolate the tobacco leaf from the air, so that an anaerobic environment is provided for the tobacco leaf, and problems such as moisture regain, mold or deterioration of the tobacco leaf are effectively avoided. Compared with the conventional kraft paper packaging, the storage time of the tobacco leaf is greatly prolonged. Moreover, the tobacco leaf is fixed on the base plate by the elastic transparent film and cannot be easily shaken, and the damage rate of the leaf tip and the leaf edge is also reduced compared with the kraft paper packaging. The integrity of the tobacco leaf is guaranteed, so that the display sample can be displayed for multiple times and transported over a long distance. In addition, the anaerobic closed environment also retains the aroma substances such as aldehydes, alcohols, ketones, alkenes, esters and pyridines generated by the tobacco leaf, and improves the exhibition experience of the visitors.

[0013] In step S1, the tobacco leaf is cleaned and dried to remove dirt on the surface of the tobacco leaf and avoid the influence of mold in the dirt on the storage period of the tobacco leaf. In step S2, the tobacco leaf is spread flat on the base plate, which facilitates the subsequent covering of the elastic transparent film. The tobacco leaf is preferably placed with the front side up, which facilitates the observation of the appearance information. In step S3, the air between the elastic transparent film and the base plate is removed to ensure that the tobacco leaf does not flow with the outside air. Except for the position of the tobacco leaf, the elastic transparent film needs to be tightly attached to the base plate. In step S4, the elastic transparent film is heated to further enhance the sealing effect of the tobacco leaf. The temperature is set to be not more than 35℃, which can avoid the deformation of the elastic transparent film caused by excessive heat. In step S5, the base plate is placed in the display box, which can protect the base plate and the tobacco leaf to a certain extent and facilitate the display.

[0014] Preferably, step S3 specifically comprises: tearing the elastic transparent film flat, fixing the elastic transparent film at one end of the base plate, fixing the position of the tobacco stem of the tobacco leaf with the hand, pulling the elastic transparent film from one end of the base plate to the other end so that the tobacco leaf is completely covered, then continuing to stretch the elastic transparent film to the back of the base plate, removing the air between the elastic transparent film and the base plate with the hand, and then folding the elastic transparent film around the base plate to the back of the base plate to ensure that the tobacco leaf in the elastic transparent film cannot contact the outside air.

[0015] Preferably, step S2 further comprises: spraying a mildew-proof agent on the surface of the tobacco leaves, and the amount of the mildew-proof agent is 8-18 g / m 2 Spraying the mildew-proof agent on the surface of the tobacco leaves can further improve the resistance of the tobacco leaves to mildew, and in cooperation with the closed environment formed by the elastic transparent film, the tobacco leaves can be prevented from mildewing and deteriorating; the amount of the mildew-proof agent is preferably 8-18 g / m 2 , and too much will cause waste, and too little will affect the effect.

[0016] Further preferably, the mildew-proof agent comprises one or more of o-phenylphenol, hexadienoic acid and benzoic acid.

[0017] Preferably, step S2 further comprises: pasting a label on the blank part of the bottom plate, and the label is marked with characteristic information of the tobacco leaves. Pasting the label with the characteristic information of the tobacco leaves on the bottom plate can help visitors to understand the basic information of the tobacco leaves.

[0018] Further preferably, the characteristic information comprises: project name, origin, variety and type.

[0019] Preferably, the bottom plate is an iron plate or a plastic plate. Compared with a wooden plate or a paper plate, the iron plate or the plastic plate will not absorb moisture or mildew in the air, so that the growth of mildew on the bottom plate can be effectively avoided, and the storage period of the tobacco leaves can be effectively prolonged.

[0020] Preferably, a gap exists between the display sample box and the bottom plate, and the gap is 0.01-0.05 mm. The display sample box and the bottom plate are provided with the gap, so that the size of the display sample box is slightly larger than that of the bottom plate, on the one hand, the bottom plate can be conveniently put in, and on the other hand, the elastic transparent film can be fixed to a certain extent, and the shaking of the bottom plate can be reduced, and the probability of damage of the tobacco leaves can be reduced.

[0021] Further preferably, the size of the display sample box is 50 cm*70 cm*6 cm.

[0022] Preferably, in step S1, the drying temperature is 50-60 DEG C.

[0023] Preferably, the elastic transparent film is a preservative film.

[0024] Compared with the prior art, the method has the following advantages:

[0025] (1) The method for making the display sample of tobacco leaves provided by the application completely wraps and fixes the tobacco leaves by the bottom plate and the elastic transparent film, forms a closed environment, reduces the damage proportion of the leaf tips and leaf edges of the tobacco leaves, guarantees the integrity of the tobacco leaves, and also retains aldehydes, alcohols, ketones, enes, esters and pyridines and other aroma substances in the tobacco leaves.

[0026] (2) The preparation method of the tobacco leaf display sample is simple and convenient, the prepared tobacco leaf can be stored for a long time, recycled, and conveniently transported and cost-saving. BRIEF DESCRIPTION OF DRAWINGS
