Abstract

The invention provides a starch-lowering aroma-improving baking process of flue-cured tobaccos. The starch-lowering aroma-improving baking process mainly comprises three baking phases including a high-temperature burning and low-temperature yellowing phase, an advanced dehumidifying and slow color fixing phase and a phased heating, aroma improving and drying phase. The starch-lowering aroma-improving baking process is characterized in that in a baking process, a circulating fan is intermittently run at the time with heat supplying and dehumidifying requirements in a whole yellowing period and a drying post-period; in the drying period, a heating manner of heating for four times and stopping for four times is adopted so that the staying time at a high-temperature period is shortened; three sections of humid ball temperature curves are set so that operation and control are facilitated. By virtue of adopting the baking process, about 15% of baking energy consumption can be saved; the ratio of badly baked tobaccos including green miscellaneous tobaccos, ash-containing tobaccos, steamed pieces and the like is obviously reduced, and the ratios of orange tobaccos and up first-class tobaccos are increased; baked tobacco leaves have much oil content, low starch content, coordinated chemical components, enough aroma and reduced irritation.

Description

technical field

[0001] The invention belongs to the technical field of flue-cured tobacco preparation, and in particular relates to a baking process for reducing starch and enhancing flavor of flue-cured tobacco. Background technique

[0002] Tobacco curing is currently one of the weakest links in flue-cured tobacco production in my country, and the quality of curing directly affects the quality of cigarettes. With the development of large-scale production of flue-cured tobacco, intensive curing barns have gradually replaced ordinary barns as the main tobacco preparation equipment in my country. Intensive barns have the characteristics of large tobacco storage capacity, forced ventilation, hot air circulation, easy operation, and a high degree of automation. , better meet the requirements of the development of modern tobacco agriculture. However, the baking process of intensive barns still relies on the traditional three-stage baking process, which can no longer meet the cur...

Examples

Embodiment 1

[0022] Example 1: Tobacco leaves 9-11 of Yunyan 87 tobacco leaves in a certain production area in Hubei Province are placed on conventional hanging rod racks, and the baking process of the present invention is adopted, and the following specific operations are carried out in an air-flow ascending intensive curing barn:

[0023] (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 of the tobacco leaf in the upper shed, it is controlled according to the temperature and humidity probe in the lower shed during baking; the flue-cured tobacco controller controls the heating and dehumidification automatically by sen...

Embodiment 2

[0030] Embodiment 2 For the central tobacco leaves of Yunyan 87 in a certain producing area in Hubei Province, the following two baking processes are adopted: T1 is a three-stage baking process (existing conventional process) for hanging rods, and T2 adopts the process described in the present invention. (Flue-cured tobacco reducing starch and flavoring baking process), according to the attached figure 1 The curing curve is set, the temperature stabilization time of each stage is adjusted in real time according to the yellowing and drying degree of the tobacco leaves, the energy consumption statistics of the curing are carried out, and the economic properties, appearance quality, chemical composition and sensory quality of the tobacco leaves are compared. The results are shown in Table 1-4.
