Problems solved by technology

Although this shortens the conditioning time and basically guarantees the quality of the air-drying tobacco style, it increases labor costs and increases the breakage rate of the leaves due to moving the tobacco leaves back and forth. It is basically disposable), sometimes due to the sun and high temperature, it is easy to cause blue smoke and burns, and at the same time increase the cost of drying and white pollution, because the area of ​​the drying shed is equivalent to that of the drying shed, it takes up valuable land resources
It can be seen from the above that although these programs are helpful to reduce TSNAs, the side effects are also very obvious

Embodiment 1

[0041] The method for airing tobacco in a smoke-drying shed using norgamine specifically comprises the following steps:

[0042] 1) Tobacco leaf withering stage: The withering stage requires that the excess water in the fresh leaves should be quickly removed, and the temperature inside the shed should be controlled at 20-22°C and the relative humidity below 80% through the heating and dehumidification circulation system for 6 days. All fresh leaves wither;

[0043] 2) Tobacco leaf yellowing stage: through the heating and dehumidification circulation system, the temperature inside the shed is adjusted to keep the temperature at 22-25°C, and the relative humidity is 65%. If the relative humidity is higher than 75%, ventilation and dehumidification should be performed in time. Make the tobacco leaves turn yellow to more than 95%;

[0044] 3) Tobacco leaf browning stage: adjust the temperature inside the shed to maintain at 22-26°C, and control the relative humidity at 70-75%. Wh...

Embodiment 2

[0048] The method for airing tobacco in a smoke-drying shed using norgamine specifically comprises the following steps:

[0049] 1) Tobacco leaf withering stage: the withering stage requires that the excess water in the fresh leaves should be quickly removed, and the temperature inside the shed should be controlled at 22-25°C and the relative humidity should be lower than 80-82% through the heating and dehumidification circulation system for 8 days. , so that all fresh leaves wither;

[0050] 2) Tobacco leaf yellowing stage: through the heating and dehumidification circulation system, the temperature inside the shed is adjusted to maintain at 20-25°C, and the relative humidity is 68-70%. When the relative humidity is higher than 75%, it is necessary to ventilate and dehumidify in time. Days, the degree of yellowing of tobacco leaves reaches more than 95%;

[0051] 3) Tobacco leaf browning stage: adjust the temperature inside the shed to maintain at 22-26°C, and control the re...

[0055] The method for airing tobacco in a smoke-drying shed using norgamine specifically comprises the following steps:

[0056] 1) Tobacco leaf withering stage: The withering stage requires that the excess water in the fresh leaves should be quickly removed, and the temperature inside the shed should be controlled at 20-25°C and the relative humidity below 78-82% through the heating and dehumidification circulation system for 7 days. , so that all fresh leaves wither;

[0057] 2) Tobacco leaf yellowing stage: through the heating and dehumidification circulation system, the temperature inside the shed is adjusted to keep the temperature at 20-25°C, and the relative humidity is 65-70%. When the relative humidity is higher than 75%, ventilation and dehumidification should be performed in time. Days, the degree of yellowing of tobacco leaves reaches more than 95%;

Abstract

Disclosed are an amine reduction tobacco curing shed and a tobacco curing method thereof. The amine reduction tobacco curing shed comprises a shed body, wherein at least one set of warming and moisture exhausting circulation system is arranged in the shed body. The at least one set of warming and moisture exhausting circulation system is used for strictly controlling temperature, moisture and atmospheric conditions and the like in a tobacco curing process, tobacco curing environment can be effectively improved, and therefore TSNAs content of cured tobacco is reduced, raw material of high quality is supplied to the cigarette industry, and harm of cigarette to consumers is reduced. The amine reduction tobacco curing shed is simple in structure. The tobacco curing technological operation is convenient. Products obtained with the tobacco curing method are stable in quality and easy to popularize.

Description

technical field [0001] The invention belongs to the technical field of tobacco leaf preparation, and in particular relates to a smoke-drying shed and a tobacco-drying method thereof. Background technique [0002] The modulation of air-dried tobacco (burley tobacco, Maryland tobacco) is to use the tobacco air-drying shed, with the help of natural sunlight and air, through certain manual control, to adjust the temperature and humidity of the tobacco leaves in the shed to complete the whole process of tobacco leaf modulation. Tobacco leaf airing is usually divided into four stages according to the sequence: withering, yellowing, browning, and tendon drying. Different natural climate conditions, different temperature and humidity, different brewing control methods, different brewing time, etc. will all affect the appearance and internal quality of tobacco leaves, thus directly affecting the income of tobacco farmers and the quality of cigarette products. [0003] It has become ...
