Example Embodiment

[0036] Example 1

[0037] 1. Test materials and methods

[0038] 1.1 Test location and variety

[0039] Location: Namu Village, Fengping Town

[0040] Variety: Yunxiang Basma No. 1

[0041] 1.2 Test materials: steel frame modulation shed; drying facility (big stove); hood wearer; thermometer and hygrometer.

[0042] 1.3 Experimental design

[0043] 1.3.1 Requirements for tobacco leaves: Tobacco leaves have good maturity, all parts are middle leaves, and good consistency.

[0044] 1.3.2 Operation management method

[0045] Simulated shed: open two small windows of 25cm×25cm at one end of the shed. Depending on the weather, uncover the two or two small windows of the shed to ensure that the average relative humidity in the shed is controlled at 70~80% and the temperature is at 27℃~37℃. Ensure that the tobacco leaves wither and turn yellow; after the withering and turning yellow, the drying facility is used to increase the temperature, intermittently opening and sealing the shed to dehumidify...

[0062] Example 2

[0063] 1. Test materials and methods

[0064] 1.1 Test site: Mangdan Village, Lujiang Town; the tested variety is Yunxiang Basma 1.

[0065] 1.2 Experimental design: Four different specifications of modulation sheds were built for the experiment, and comparative experiments were carried out.

[0066] A. The specifications of the modulation shed are: medium height 1.6m, side height 0.8m, width 3m, and length 6m; (the modulation shed used in the original production of CK) (one set of three gears, 1m per gear)

[0093] Example 3

[0094] 1 Test (demonstration) materials and methods

[0095] 1.1 Test site: Mandan Point in Lujiang Town, Longtan Point in Kas Town

[0096] 1.2 Test design: A total of three batches (stages) of tests were carried out. There are five treatments in the first stage, and four treatments in the second and third stages.

[0097] 1.3 Demonstration site: Set up one spot each in Lujiang Mangdan and Kaslongtan.

Abstract

The invention discloses an aromatic tobacco curing method. The method includes the steps of shed building, tobacco stringing and racking, a withering and yellowing stage, a leaf-drying stage and a stem drying stage, and specifically includes: selecting a flat, ventilative and sunny place to build a curing shed, classifying aromatic tobacco leaves according to picked same parts, stringing the aromatic tobacco leaves prior to racking and hanging the aromatic tobacco leaves into the curing shed; well controlling indoor temperature and fermentation time, finishing curing after the tobacco leaves undergo the withering and yellowing stage, the leaf-drying stage and the stem drying stage, removing the cured tobacco leaves from a rack, and storing the cured tobacco leaves according to harvest batches and/or parts. The tobacco leaves are cured mainly depending on sunlight through a mode focusing on drying in the sun and combining airing and drying, the obtained high quality of the cured tobacco leaves is fixed, the cured tobacco leaves are prevented from changing from yellow to red, brown or black, and the tobacco leaves are more aromatic and more mellow in taste.

Description

technical field [0001] The invention belongs to the technical field of tobacco agriculture, and in particular relates to a preparation method of oriental tobacco. Background technique [0002] Tobacco leaves are an important basis for determining the quality of cigarette brands. The quality characteristics and registration structure of tobacco leaves affect the style and taste characteristics of cigarettes. The quality of tobacco leaves can be measured by maturity. The maturity of tobacco leaves includes the maturity of fresh tobacco leaves in the field and the maturity after modulation. The maturity of tobacco leaves in the field is the maturity of tobacco leaves in the process of growth and development in the field. The basis for later assurance of maturity. Tobacco leaves have good maturity in the field, and must be adjusted in the correct way to ensure that the final tobacco leaves have high quality and good maturity. [0003] At present, most of the tobacco leaves are...
