Description

Technical Field

[0001] This invention relates to the field of tobacco processing technology, and in particular to a method for simulating re-drying and aging of small sample quantities of tobacco leaves. Background Technology

[0002] Re-drying and aging are two key steps in tobacco raw material processing. Re-drying is a processing step that takes place after the initial curing of tobacco leaves. Through re-drying, tobacco leaves are transformed from agricultural products into industrial raw materials. In this process, the initial curing of tobacco leaves removes impurities and irritants, and the moisture content of the leaves reaches a reasonable range, which is beneficial for subsequent aging and storage. Aging is a process under certain environmental conditions where, through a series of chemical and biological reactions, components detrimental to the quality of tobacco leaves are transformed into components that enhance their quality.

[0003] During the production process, the amount of tobacco leaves re-drying and aging is relatively large. Common re-drying production lines have a capacity of 12,000 kg of tobacco leaves / hour, and aging parcels have a capacity of 200 kg of tobacco leaves / box. In the breeding of new tobacco varieties, it is necessary to conduct field planting of intermediate materials to examine their phenotypic characteristics, chemical composition, sensory quality, and industrial usability. For example, when creating and researching intermediate materials for the Honghua Dajinyuan variety, there are usually many intermediate materials, with each intermediate material typically planted on no more than one acre, yielding approximately 150 kg of first-cured tobacco leaves. After selection and grading according to tobacco grade, these are used for re-drying. The tobacco leaves used for re-drying are of grade C3F and above, which yields approximately 65 kg. This grade cannot be used for re-drying and aging on existing production lines, making subsequent industrial usability verification and evaluation impossible.

[0004] Therefore, there is an urgent need for a method to simulate the re-drying and aging of tobacco leaves with a small sample size. Summary of the Invention

[0005] The purpose of this invention is to provide a simulated re-drying and aging method for small sample sizes of tobacco leaves to solve the problems in the prior art. This method enables the re-drying and aging of small sample sizes of tobacco leaves using existing production lines to obtain tobacco leaves that meet the requirements for subsequent industrial usability verification and evaluation.

[0006] This invention provides a method for simulating re-drying and aging of small sample sizes of tobacco leaves, comprising the following steps:

[0007] A small sample of tobacco leaves after initial curing was destemmed and torn into pieces to obtain sheet tobacco.

[0008] The tobacco leaves are bagged.

[0009] The bagged tobacco leaves are re-dried on the re-drying production line;

[0010] The re-dried tobacco leaves are then compressed and boxed.

[0011] The packaged tobacco leaves undergo an aging process.

[0012] The simulated re-drying and aging method for a small sample size of tobacco leaves, as described above, preferably includes the following steps: Destemming and tearing the initially dried tobacco leaves to obtain sheet tobacco.

[0013] The stems of the first-cured tobacco leaves are removed by hand to remove impurities and dust;

[0014] After removing impurities and dust, the first-cured tobacco leaves are torn into pieces.

[0015] In the simulated re-drying and aging method for small sample tobacco leaves as described above, preferably, the length and width of the tobacco leaves after the tearing process are 5cm-10cm.

[0016] The simulated re-drying and aging method for small sample sizes of tobacco leaves described above, preferably, includes the following step: bagging the tobacco leaves.

[0017] The tobacco leaves are placed into a mesh bag and then tied with a net rope.

[0018] In the simulated re-drying and aging method for small sample quantities of tobacco leaves described above, preferably, the length and width of the mesh bag are 40cm-50cm, and the weight of the tobacco leaves packed in each mesh bag is 280g-320g.

[0019] The simulated re-drying and aging method for small sample sizes of tobacco leaves described above, preferably, involves re-drying the bagged tobacco leaves on the re-drying production line, specifically including:

[0020] The mesh bags containing the tobacco leaves are placed on the re-drying production line;

[0021] The tobacco leaves in the mesh bag are re-dried according to the re-drying production process of vacuum rehydration, leaf moistening, and leaf re-drying.

[0022] The simulated re-drying and aging method for small sample sizes of tobacco leaves described above, preferably, involves the following steps: pressing and packing the re-dried tobacco leaves.

[0023] The re-dried tobacco leaves are loaded into a pressing mold for pressing.

[0024] The compressed and shaped re-dried tobacco sheets are packed into cardboard boxes.

[0025] In the simulated re-drying and aging method for small sample quantities of tobacco leaves described above, preferably, the length of the pressing mold is 18cm-22cm, the width is 18cm-22cm, and the thickness is 13cm-17cm; and the internal dimensions of the carton are consistent with the internal dimensions of the pressing mold.

[0026] The simulated re-drying and aging method for small sample sizes of tobacco leaves described above, preferably, involves aging the packaged tobacco leaves, specifically including:

[0027] The cardboard boxes containing the re-dried tobacco were labeled with sample numbers and placed in the aging storage room for natural aging.

[0028] The present invention provides a method for simulating re-drying and aging of small sample quantities of tobacco leaves. This method allows for the re-drying and aging of small sample quantities of tobacco leaves on existing re-drying production lines, yielding tobacco leaves that meet the requirements for subsequent industrial usability verification and evaluation. Manual destemming and leaf tearing replaces the leaf-beating process on the production line, achieving destemming and leaf-beating for small sample quantities of tobacco leaves. After packaging the tobacco leaves, the re-drying process is carried out on the re-drying production line, solving the problem of uneven dispersion caused by the small quantity of tobacco leaves on the re-drying production line. A pressing mold is used to press and shape the re-dryed tobacco leaves, simulating the conventional aging process of pressing tobacco leaves into packaging boxes for aging.
