Problems solved by technology

[0002] Improving the usability of the upper leaves of flue-cured tobacco has been a research hotspot in recent years. The upper leaves with better maturity have more aroma, and can still retain more aroma after decoking treatment. Poor performance is still a prominent contradiction in production
The harvesting time of the upper leaves in most of the tobacco areas in my country is usually from late September to early October. During this period, the temperature is low, which is not conducive to the maturity of the upper leaves, resulting in poor maturity of the upper leaves when harvested in the field, and cyanosis is easy to appear after roasting. (Blue veins, floating green), hanging ash, roasted red and other variegated smoke phenomena have seriously affected the interests of tobacco farmers and enterprises
The current upper leaf roasting process mainly relies on the traditional three-stage roasting process, which can no longer meet the current needs of upper leaf roasting
Although the three-stage five-step tobacco leaf curing process disclosed in Chinese Patent Publication No. CN1444879 and the precise curing process of flue-cured tobacco intensive curing barn disclosed in Publication No. CN102178335A reduce the proportion of green leaf smoke in the upper part and improve the appearance quality to a certain extent, The upper leaves with poor maturity are harvested, and the proportion of green and miscellaneous smoke in the roasted tobacco leaves is higher

Embodiment 1

[0015] Embodiment 1: For Yunyan 87 from a production area in Hubei Province, four upper leaves are harvested at one time, and conventional hanging rods are used to load tobacco, and the baking process of the present invention is adopted, and the following specific operations are carried out in the air-flow ascending dense curing barn:

[0016] (1) The intensive curing room is equipped with flue-cured tobacco controllers, fans, cold air doors, and temperature and humidity probes; for the inspection of the baking equipment before loading tobacco, the temperature and humidity probes are installed in the lower shed of the tobacco loading room and the probes are hung at the tip of the tobacco leaves in the lower shed, and the probes in the upper shed are hung At the tip position of the tobacco leaves in the upper shed, the temperature and humidity probes in the lower shed are used to control during curing; the flue-cured tobacco controller controls the heating and dehumidification au...

Embodiment 2

[0022] Embodiment 2 For the upper tobacco leaves of Yunyan 87 in a certain producing area in Hubei Province, the following two curing processes are adopted: T1 adopts a three-stage curing process (existing conventional process) for hanging rods, and T2 adopts the process described in the present invention (upper leaf maturation-promoting baking process), according to the attached figure 1 The curing curve is set, and the temperature stabilization time of each stage is adjusted in real time according to the yellowing and drying degree of the tobacco leaves, and the economic properties, appearance quality, chemical composition and sensory quality of the cured tobacco leaves are compared. The results are shown in Table 1-3.

Abstract

The invention provides a flue-cured tobacco upper leaf ripening accelerating baking technology. The baking technology mainly comprises an earlier stage low-temperature ripening accelerating stage, a high-temperature yellowing water loss stage, a low-temperature hydrofuge slow fixation stage and a killing-out stage. The technology mainly solves the problem that the harvesting maturity is not enough due to the fact that the field temperature is low for the flue-cured tobacco upper leaf ripening period, by controlling the earlier stage yellowing temperature and humidity environment of a bulk curing barn, the upper leaves are ripened inside the curing barn after being harvested, the ripeness of the baked upper leaves is improved, green miscellaneous tobacco is reduced, the proportion of orange tobacco to first-class tobacco is increased, and the baked tobacco leaves are high in oil content, low in starch content, coordinate in chemical component, enough in fragrance and low in irritation.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco preparation, and in particular relates to a curing process for promoting ripening of upper leaves of flue-cured tobacco. Background technique [0002] Improving the usability of the upper leaves of flue-cured tobacco has been a research hotspot in recent years. The upper leaves with better maturity have more aroma, and can still retain more aroma after decoking treatment. Poor performance is still a prominent contradiction in production. The harvesting time of the upper leaves in most of the tobacco areas in my country is usually from late September to early October. During this period, the temperature is low, which is not conducive to the maturity of the upper leaves, resulting in poor maturity of the upper leaves when harvested in the field, and cyanosis is easy to appear after roasting. (Blue veins, floating green), hanging ash, roasted red and other variegated smoke phenomena have s...
