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.

[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 and yellowing dense hanging rod baking method for middle and upper tobacco leaves, which belongs to the technical field of three-stage dense hanging rod baking technology for flue-cured tobacco, mainly including three stages and nine steps, and the main turning of the middle and upper tobacco leaves is yellowing. In the early stage, use medium temperature to moisturize and turn yellow, keep the temperature difference between dry and wet bulbs at zero, and bake at a stable temperature for 35-50 hours. When the yellowing degree of the tobacco leaves reaches the yellow veins, slowly increase the temperature and dehumidify, so as to increase the high-quality tobacco rate of the middle and upper tobacco leaves. , orange-yellow tobacco rate and average price, improve the chemical composition coordination and sensory evaluation quality of cured tobacco leaves, improve the quality of cured tobacco leaves, increase profits, and increase the income of tobacco farmers.

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...
