Problems solved by technology

[0007] However, due to the vast territory of our country, the quality of tobacco leaves and the baking environment are not the same. At the same time, the tobacco density of our country’s tobacco farmers is far from meeting the design requirements. During the baking process, tobacco farmers are accustomed to using high-speed circulating fans, using low-temperature, medium-humidity and yellowing. Roasting has certain limitations. Tobacco farmers often apply the baking process of ordinary curing rooms in the actual baking operation, which to a certain extent leads to too fast drying of tobacco leaves, insufficient degradation of protein and starch in tobacco leaves, and the leaves are prone to smooth, dry leaves after roasting. Phenomena such as stiffness and light color reduce the oil content and aroma of tobacco leaves, which affect the industrial usability of tobacco leaves. In recent years, the cigarette industry has responded strongly to this

Embodiment 1

[0047] The tested flue-cured tobacco varieties of the present invention are Yunyan 87, Yunyan 85 and K326, and the parts and maturity balance of the tested tobacco leaves are basically the same.

[0048] 1. Experimental settings

[0049] Set up experimental groups T1, T2, T3, T4, and T5 to explore the influence of wet bulb temperature on tobacco leaf quality during the main yellowing period of tobacco leaves.

[0052]

[0053] The above test was set at 37°C-38°C during the main yellowing period of the tobacco leaves. The dry bulb temperature was stabilized and different wet bulb temperatures were set until the tobacco leaves turned 80% yellow.

[0116] 1. Experimental settings

[0117] Three treatments were set up in the experiment: middle temperature and moisturizing intensive yellowing roasting T1, conventional roasting T2 and loose leaf roasting T3. See Table 12 for the specific settings. During the roasting process, samples were taken every 6 hours to measure the moisture, dry matter, starch, total sugar, reducing sugar, protein, amino acid, nicotine and other chemical components of the tobacco leaves, as well as the enzyme activities such as amylase and protein enzyme (enzyme activity was sampled to 120 ℃).

Abstract

The invention discloses a medium-temperature moisturizing yellowing dense hanging rod baking method for middle-upper tobacco leaves. The invention belongs to the technical field of flue-cured tobaccothree-section type dense hanging rod baking processes. The method mainly comprises nine steps of three sections. Medium-temperature moisturizing yellowing is adopted in the main yellowing stage of themiddle-upper tobacco leaves, the temperature difference of dry and wet bulbs is kept to be zero, and baking is carried out for 35-50 h at a steady temperature; when the yellowing degree of the tobacco leaves reaches a state with yellow sheet and green tendons, the temperature is slowly increased for dehumidification, so that the first-class tobacco rate, the orange tobacco rate and the average price of the cured middle-upper tobacco leaves are increased, the chemical component coordination and the sensory evaluation quality of the cured tobacco leaves are improved, the quality of the cured tobacco leaves is improved, profits are increased, and income increase of tobacco growers is achieved.

Description

technical field [0001] The technical field of the present invention is a three-stage intensive rod-hanging baking process for flue-cured tobacco, and specifically relates to a method for densely hanging rod-roasting at medium temperature, moisturizing and yellowing of middle and upper tobacco leaves. [0002] technical background [0003] Tobacco leaf curing is the most important link in flue-cured tobacco production that determines the quality, yield and availability of flue-cured tobacco. It is also the main factor that directly affects the economic income of tobacco farmers, the quality and economic benefits of cigarette industry products, and the formation of tobacco leaf quality, use value and economic value. It is jointly determined by field growth management and scientific curing, which shows the importance of curing in the quality of tobacco leaves and flue-cured tobacco production. [0004] Intensive curing barn is an essential infrastructure to promote the scale, in...
