Embodiment 1

[0018] Embodiment 1: (the flue-cured tobacco curing process that prevents and cures the black ant skin symptom to produce during the tobacco leaf curing process is applied to the common air-flow ascending barn)

[0019] ① Low temperature humidity control turns yellow

[0020] In the stage of tobacco leaves turning yellow under low temperature and humidity control, from the appearance of tobacco leaves to the internal physiology and biochemistry, the chemical composition that changes a lot is chlorophyll. The specific measures are: use lower temperature and slightly higher humidity to make the tobacco leaves heated→lose water→soften→collapse→turn yellow. The principle to master is "burning fire should be small and patient". "Loss of water is compatible with yellowing, and it turns yellow while draining moisture."

[0021] Before ignition, the exhaust window and air inlet tunnel are opened by 1 / 3 to 1 / 4. After firing, at an average heating rate of 1°C / h, within 14-17 hours, t...

Embodiment 2

[0032] Embodiment 2: (the flue-cured tobacco curing process that prevents and treats the black ant skin symptom during the tobacco leaf curing process is applied to an intensive automatic curing barn)

[0033] ① Low temperature humidity control turns yellow

[0034] During the yellowing period of tobacco leaves, the degradation of chlorophyll is the most influential factor from the appearance of tobacco leaves to the internal physiology and biochemistry. The specific measures are: under the conditions of appropriate low temperature and low humidity, the tobacco leaves are heated→losing water→softening→collapsing→turning yellow. The principle to master is: "Keep the fire small and patient." "Loss of water is compatible with yellowing, and it turns yellow while draining moisture." The key technology is "controlling humidity with temperature".

[0035] After a fire, at an average heating rate of 1°C / h, within 14 to 17 hours, raise the dry bulb temperature of the bottom platfor...

Abstract

The invention relates to a tobacco roasting technique preventing and treating a Heimapi symptom (a symptom that the tobacco leaves turn black and have flecks or blocks partially or whole) in a tobacco roasting process, belonging to the technical field of tobacco preparation. The technique is as follows: after filling the tobacco leaves in a furnace, keeping the temperature less than 40 DEG C and the relative humidity at 92%-82% to <=79% or to <=68%, with the change curve sharply dropped; keeping balancing the relative humidity of an intensive roasting room to less than or equal to 85%; (1) adjusting humidity at a low temperature until turning yellow, roasting the tobacco leaves on the base frame until stems turn green and leaves turn yellow, with the temperature in the furnace between 40 DEG C and 48 DEG C and the relative humidity of the common roasting room changed from less than or equal to 68% to less than or equal to 64% to less than or equal to 45%-38%, also with the change curve sharply dropped; stabilizing the temperatures and discharging moisture until the leaves wilt, all the tobacco leaves in the furnace turn white and the tips turn up; go on roasting according to the normal method until all the tobacco leaves are dry after the temperature in the furnace is 49 DEG C. The invention has advantages of a simple operation, overcomes over 85% of tobacco leaves with the Heimapi symptom and obviously improves roasted tobacco leaves, and is applied to roasting tobacco leaves in cold areas and upper tobacco leaves.

Description

Technical field: [0001] The invention relates to a flue-cured tobacco curing process for preventing and curing black ant skin symptoms during the tobacco leaf curing process, and belongs to the technical field of flue-cured tobacco modulation technology. Background technique: [0002] In the production of flue-cured tobacco, varieties and cultivation are the foundation, and baking is the key. Curing is a key link that determines the quality of tobacco leaves, and it is also a weak link in China's tobacco production, and a bottleneck that restricts the further development of China's tobacco production. The most restrictive factor to improve the quality of tobacco leaves curing is the large amount of tobacco leaves with black skin symptoms produced during the curing process of the upper tobacco leaves. According to the investigation, the loss of the tobacco leaves with black leech symptoms during the curing process is usually between 10% and 15%. The people in the smoking ar...
