Description

Technical Field

[0001] This invention relates to the field of tobacco processing technology, and in particular to a packaging method for protecting the appearance of cigar wrapper tobacco leaves. Background Technology

[0002] As a special tobacco product, cigars possess a unique aroma and charm, characterized by a strong flavor, high strength, rich aroma, and low tar content. In recent years, the global cigar market has shown a trend of expansion and structural improvement. The tobacco leaves used in handmade cigars can be divided into three parts from the outside in, according to their purpose: the wrapper, the binder, and the filler. The wrapper tobacco is the outermost layer of a cigar, requiring an attractive appearance, even color, gloss, sufficient oil content, thinness, good and even burning, fine and complete veins, and appeal to smokers. The binder tobacco is usually thinner than the filler tobacco and mainly serves to hold the filler tobacco in place. The filler tobacco is the main part of the cigar, primarily composed of thick tobacco leaves with good burning properties and a rich, aromatic flavor.

[0003] Cigar wrappers require extra care during packaging and transportation due to their high standards. Traditional burlap sack packaging is prone to breakage and damage, affecting their integrity and usability. On the other hand, overly tight sealing during transportation can easily lead to mold growth. Summary of the Invention

[0004] The purpose of this invention is to provide a packaging method that protects the appearance of cigar wrapper tobacco leaves in order to solve the aforementioned problems. This invention involves packing the cigar wrapper tobacco leaves, after agricultural fermentation, into a cardboard box head-to-head, with the stem facing the narrow side of the box. Perforations are made on the side of the box facing the stem. The top and bottom of the box are lined with breathable, preservative-treated wood material, which effectively increases gas exchange inside the box and reduces the risk of mold growth on the contact surfaces. Furthermore, the specially treated preservative-treated wood material contains cinnamon extract, which has antibacterial and anti-mold properties. By using this invention to package and transport cigar wrapper tobacco leaves, the mechanical damage and mold risk during packaging and transportation can be effectively reduced, achieving the goal of cost reduction and efficiency improvement.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0107] The packaging of cigar tobacco leaves involves multiple processes, including weighing, boxing, pressurizing, and bundling. Among these, the pressing process poses the greatest threat to the pressing of oil into the tobacco leaves, essentially marking the starting point for this process. Even when packaged according to normal procedures and prescribed volume and weight requirements, some degree of oil pressing is unavoidable. Secondly, in recent years, the addition of purification and processing steps has meant that tobacco leaves purchased by various counties must undergo warehousing inspection and purification processing by the tobacco management department before being transported to the threshing and re-drying plant, requiring two packaging processes, and in some cases, even three. This repeated processing is a significant factor contributing to severe oil pressing in the tobacco leaves. Finally, from a transportation perspective, neglecting the maintenance of tobacco quality and intentionally compressing the tobacco bales too thinly and tightly also contributes to oil pressing.

[0108] As shown in Tables 1, 2, 3, and 4, the method described in this invention, compared to traditional burlap sack packaging, significantly reduces the amount of cigar wrapper pressed into the tobacco leaves and the degree of damage. This is mainly because high-quality cigar wrappers are highly hygroscopic and contain ample oil, leading to severe oil pressing during traditional packaging, loading, unloading, and transportation. The packaging method of this invention reduces compression between tobacco leaves. Secondly, tobacco leaves are extremely sensitive to moisture; increased moisture easily breeds mold, leading to mildew spots. The perforated cardboard boxes of this invention increase air circulation within the box, reducing the formation of mold.

[0109] Using breathable paper, waterproof wallpaper, and preservative-treated wood materials, the method described in this invention significantly reduces the mold growth on cigar wrappers compared to traditional palm leaf packaging. Preservative-treated wood shows the best results, as its active ingredients protect the wood from wood-decaying fungi, blue stain fungi, and mold growth. Furthermore, its good breathability prevents prolonged high moisture content, thus inhibiting mold growth. Results show that the specially treated preservative-treated wood material, with cinnamon extract sprayed onto its surface, reduced mold growth by 12.2% and 5.5% respectively compared to traditional palm leaf packaging and untreated preservative-treated wood packaging, significantly reducing mold growth on cigar wrappers and improving the appearance quality of cigar tobacco. The main component of cinnamon extract is cinnamaldehyde, which can enter cells by damaging the cell membrane of mold cells, altering the spatial structure of intracellular proteins and rendering them biologically inactive. This disrupts the absorption, transport, and metabolic pathways of mold, thereby inhibiting mold growth.

[0110] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
