Description

Technical Field

[0001] The present invention relates to the technical field of tobacco processing, and in particular to a method for processing cigar wrappers. Background Art

[0002] As a high-end tobacco product, cigars are highly favored by consumers for their quality and flavor. During the processing and production of cigars, the quality of the wrapper (the tobacco leaves wrapped around the outside of the cigar) has a decisive influence on the taste and aroma of the final product. Traditional cigar wrapper processing methods mainly rely on natural airing and drying. Although these methods can remove some moisture and bad odors, they often cannot fully stimulate the quality potential of the wrapper and achieve the best flavor and aroma, and are greatly restricted by environmental conditions. With the growing demand for high-quality cigars from consumers, it is particularly urgent to develop a low-cost processing method that can significantly improve the quality of cigar wrappers.

[0003] The prior art known to the inventors discloses a cellar processing method for improving the sensory quality of cigar tobacco leaves (CN117158625 A), which changes the sensory quality of cigar tobacco leaves to a certain extent; however, in the process of implementing the technical solution in the embodiments of the present application, the inventors of the present application found that the above-mentioned technology has at least the following technical problems: the tobacco leaf processing procedures are complicated, the processing takes a long time, and it is necessary to introduce additional exogenous flavor media and white wine cellar mud, which not only easily masks the taste of the cigar tobacco leaves themselves, but also the processing cost is high.

[0004] The information disclosed in this background technology section is only used to deepen the understanding of the background technology of the present disclosure, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art known to those skilled in the art. Summary of the invention

[0005] The inventors have found through long-term experimental research that processing cigar wrappers in a well kiln (used to create conditions such as constant temperature and humidity, avoiding light and oxygen, etc.) can make full use of the local ecological and microecological environment. The tobacco leaves are in a constant temperature and humidity, high humidity and low temperature environment during the processing (easy for the enrichment and growth of microorganisms), which is conducive to the slow and stable fermentation of the tobacco leaves, and can further stimulate the wrappers themselves to produce a variety of flavor components, and is conducive to improving the uniformity of the moisture content of the tobacco leaves after the drying, so that the homogenization degree of the tobacco leaf processing process is improved, the color is dark and uniform, and the leaf tension is good. Based on this, the present disclosure provides a cigar wrapper processing method that is processed through a well kiln and does not require the additional introduction of exogenous substance preparations, and reduces the processing cost of this application by optimizing the processing technology, while improving the homogenization degree of the wrapper processing, making the leaf color darker, the sensory quality improved, and fully stimulating the wrapper to generate more aromatic substances.

[0006] According to one aspect of the present disclosure, a cigar wrapper pit-type processing method is provided, comprising the following steps: (1) Select or dig a corresponding well kiln, isolate the soil around the wall of the well kiln, and then lay a layer of gravel and a layer of wood on the bottom of the kiln in sequence; (2) Select the tobacco leaves from the lower second shed and / or the middle part with a leaf age of 45 to 50 days and air-dry them; (3) Tie the dried tobacco leaves into bundles and balance their moisture content to 18-25%; (4) Stacking the bundles of tobacco leaves after the moisture content is balanced, with the bundles facing outwards and the tips facing inwards, and laying the bundles flat inside the bundles; (5) After the piles are stacked to the top of the pit, a wooden board layer, a 10-15 cm thatch layer, and a 5-10 cm dry soil layer are laid on the top of the pit in sequence, leaving a 40-60 cm gap at the top edge; (6) When the processing and fermentation time reaches 45 to 65 days, the tobacco leaves are moved out of the well cellar and hung on poles to dry naturally in the shade for 1 to 3 days. When the moisture content is adjusted to 17 to 19%, they are stored in the warehouse.

[0007] In some embodiments of the present disclosure, in step (1), the well kiln is arranged in a drying room.

[0008] In some embodiments of the present disclosure, in step (1), non-woven fabric is used to isolate the soil on the surrounding wall of the pit.

[0009] In some embodiments of the present disclosure, in step (1), the specifications of the pit kiln are 1.5 to 2.5 m high, 1.5 to 2.0 m wide, and 2 to 3 m long below the ground.

[0010] In some embodiments of the present disclosure, in step (1), the thickness of the gravel layer is 5 to 15 cm, and the thickness of the wooden board layer is 3 to 5 cm.

[0011] In some embodiments of the present disclosure, when the temperature of the core of the stack reaches 30-35°C, the stack is turned over, and the lower layer of tobacco leaves are turned to the upper layer, and the core tobacco leaves are turned to the outer layer.

[0012] In some embodiments of the present disclosure, in step (4), the tobacco leaves are bundled into 15 to 25 leaves per bundle.

[0013] In some embodiments of the present disclosure, in step (4), the specifications of the cigarette stack are 1.2 to 2.3 m in height, 1.1 to 1.3 m in width, and 1.8 to 2.8 m in length.

[0014] One or more technical solutions provided in the embodiments of the present application have at least any of the following technical effects or advantages: 1. Improve quality: By utilizing the natural temperature and humidity of the underground environment, slow biochemical changes can occur inside the tobacco leaves (microbial reproduction and metabolism, enzymatic reactions, etc., which help improve the aroma, taste and quality of the tobacco leaves). The natural processing of cigar wrappers can be achieved without introducing exogenous substances, thereby improving the maturity and sensory quality of the tobacco leaves, making the processed cigars more mellow, sweet, slightly bitter, and with a long aftertaste.

[0015] 2. Stabilize the processing effect: Cellar or well cellar processing can reduce the impact of the external environment on the processing process and ensure the stability and consistency of the processing effect.

[0016] 3. Cost saving: The well kiln used in the well-cellar processing of the present application is at the bottom of the air-drying room. The size of the well kiln is designed according to the specifications of the air-drying room, which is conducive to the tobacco leaves entering the processing link immediately after the air-drying. The moisture content of the tobacco leaves processed by the well-cellar type will be increased, reducing the crushing in the later grading and purchasing links. The processing method provided by the present application has a simple process flow and a low processing cost, which improves the initial processing quality of the tobacco leaves, can improve the degree of homogenization of the cigar wrapper processing, deepen the color of the cigar wrapper leaves, improve the sensory quality, and save labor costs.

Figures 1 to 3 As shown, non-woven fabric is used to isolate the soil on the walls of the well cellar, and a 10.0 cm layer of crushed gravel and a 4.0 cm layer of wooden boards are laid in sequence on the bottom of the cellar.

[0025] (2) Select the leaves with an age of 48 in the lower second shed (the 6th leaf from bottom to top) and the middle leaves (the 9th leaf from bottom to top). After air-drying, select the leaves with uniform leaf color and complete leaves.

[0026] (3) Tie the dried leaves into bundles with 20 leaves in each bundle, balance the moisture content of the dried tobacco bundles and control the moisture content at 21.5%.

[0027] (4) Stack the tobacco leaves in bundles according to the specifications of 2.0m in height, 1.2m in width and 2.3m in length. The bundles are laid flat with the heads facing outwards and the tips facing inwards. The bundles inside the bundle are laid flat and laid vertically according to the specified length, width and height; see Figure 4.

[0028] (5) After the pile is stacked to the top of the pit, a wooden board layer, a 12.5 cm thatch layer, and a 7.5 cm dry soil layer are laid on the top of the pit in sequence, leaving a 50 cm gap at the top edge.

[0029] (6) When the temperature of the center of the stack reaches 32°C, turn the stack over. Turn the lower layer of tobacco leaves to the upper layer, and the center of the stack to the outer layer.
