Problems solved by technology

[0003] At present, most of the tobacco leaves are prepared by baking. Aroma is one of the important indicators to evaluate the internal quality of tobacco leaves. The aroma-causing substances in tobacco leaves are complex, and the content of substances called essential oils is small but extremely large. Affect the quality and quantity of tobacco aroma
The current tobacco leaf curing technology has the problem that the tobacco leaves after modulation will change from yellow to red, brown or black

Embodiment 1

[0037] 1. Test materials and methods

[0038] 1.1 Test location and species

[0039] Location: Namu Village, Fengping Town

[0040] Variety: Yunxiang Basma No. 1

[0041] 1.2 Materials to be tested: steel frame conditioning shed; drying facility (big furnace); smoke-piercing machine; temperature and humidity meter.

[0042] 1.3 Experimental design

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

[0044] 1.3.2 Operation and management methods

[0045] Simulation shed: Open two small windows of 25cm×25cm at one end of the shed. Depending on the weather, uncover the two ends 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 27°C~37°C. Ensure that the tobacco leaves wither and turn yellow; after withering and turning yellow, heat up the drying facilities, open and close the shed intermittent...

Embodiment 2

[0063] 1. Test materials and methods

[0064] 1.1 Test location: Mandan Village, Lujiang Town; the tested variety is Yunxiang Basma No. 1.

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

[0066] A. The specifications of the modulation shed are: middle height 1.6m, side height 0.8m, width 3m, length 6m; (the modulation shed used in the original production of CK) (one set with third gear, 1m / level)

Embodiment 3

[0094] 1 Test (demonstration) materials and methods

[0095] 1.1 Test location: Mandan Point of Lujiang Town, Longtan Point of Kasi Town

[0096] 1.2 Experimental design: A total of three batches (phases) of experiments were carried out. Among them, there are five treatments in the first stage, and four treatments in the second and third stages.

[0097] 1.3 Demonstration locations: Lujiang Mandan and Kasi Longtan respectively set up a site.

[0098] 1.4 Demonstration design:

[0099] Withering and yellowing: the required temperature is 28°C-40°C, the relative humidity is >70%, and the degree of yellowing reaches 50%. In the case of dry climate and strong light, new tobacco leaves should be covered with shading objects for 1-40°C. 5 days (the number of shaded days can be determined according to the degree of yellowing). Close the window at 17:00 in the evening and open the window at 11:00 in the morning for 1 to 7 days in the shed. Open one end on the 1st to 3rd day, and o...

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...
