Tobacco flue-curing method for bulk curing barn

Abstract

The invention relates to the technical field of flue-cured tobacco modulation, in particular to a tobacco flue-curing method for a bulk curing barn. The flue-curing process of the tobacco flue-curing method includes a yellowing period, a withering period, a stem yellowing period, a tobacco leaf drying period and a stem drying period according to factors such as dry-bulb temperature, wet-bulb temperature, drying time, heating rate, variable speed ventilation and tobacco leaf change targets, a color fixing period in the traditional tobacco flue-curing method is prolonged at a fixed point and steady temperature under the condition of hot air circulation, and sufficient decomposition and transformation of amylum, protein and other macromolecular substances in tobacco leaves and forming of aromatic matters are promoted. The tobacco flue-curing method for the bulk curing barn is easy to operate, safe and secure, can keep tobacco leaf yellow to be stable, leaf shrinking degree to be good, oil content to be increased and tobacco leaf aromatic amount to be increased greatly, further can reduce or avoid tobacco leaf roasting damage of green smoke roasting, ash smoke hanging, black bad smoke, lousy smoke roasting and the like, and can obtain high-quality tobacco leaves through roasting.

Description

technical field [0001] The invention relates to the technical field of flue-cured tobacco preparation, in particular to a tobacco leaf curing method used in a dense barn. Background technique [0002] During the curing process of tobacco leaves, due to the high density of smoke in the dense barn (3 to 4 times the smoke density of ordinary barns), fans are used for forced ventilation, hot air circulation, and automatic temperature and humidity control. The advantages of labor cost reduction and labor intensity reduction adapt to the new situation of sustainable development of flue-cured tobacco production and modern tobacco agriculture, and represent the development direction of tobacco leaf curing equipment in the future. [0003] At present, the intensive curing barn still implements the three-stage tobacco leaf curing method. After the tobacco leaf turns yellow, the method quickly raises the temperature and fixes the color. The baking time is shorter than that of the ordin...

AI Technical Summary

Problems solved by technology

[0003] At present, the three-stage tobacco leaf curing method is still implemented in intensive curing barns. After the tobacco leaves turn yellow, the method quickly raises the temperature to fix the color, and the curing time is relatively short. The time for curing tobacco leaves in ordinary barns has been shortened, resulting in insufficiently decomposed polymer compounds being fixed in the cells of the tobacco leaves. After curing, the tobacco leaves often appear light in color, stiff, smooth, or even green, and lack aroma Decreased baking quality
