Embodiment 1

[0025] The smoke loading method of the baking process of the present invention is to make the direction of the tobacco rod the same as the wind direction of the air inlet, such as figure 2 As shown, the post-curing after loading the smoke includes six stages:

[0026] Step 1: After loading the tobacco leaves into the furnace, ignite the fire, raise the temperature of the dry bulb to 35°C within 4 hours, and control the temperature of the wet bulb at 35°C, and then stabilize the temperature for 8 hours, so that the tip of the tobacco leaves turns yellow by 3 cm, and the leaves become sweaty. soft. The goal of this stage is to warm and sweat the tobacco leaves just loaded into the barn, create a humidity environment for the tobacco leaves to turn yellow, and prevent the tobacco leaves from "hard and yellow".

[0027] Step 2: When the changes of the tobacco leaves meet the requirements of the first step, raise the dry bulb temperature to 38°C at a rate of 1°C / h, while controlli...

Embodiment 2

[0038] The smoke loading method of the baking process of the present invention is to make the direction of the tobacco rod the same as the wind direction of the air inlet, such as figure 2 As shown, the post-curing after loading the smoke includes six stages:

[0039] Step 1: After loading the tobacco leaves into the furnace, ignite the fire, raise the temperature of the dry bulb to 34°C within 4 hours, and control the temperature of the wet bulb at 33°C, and then stabilize the temperature for 8 hours, so that the tip of the tobacco leaves turns yellow by 3 cm, and the leaves become sweaty. soft. The goal of this stage is to warm and sweat the tobacco leaves just loaded into the barn, create a humidity environment for the tobacco leaves to turn yellow, and prevent the tobacco leaves from "hard and yellow".

[0040] Step 2: When the changes of the tobacco leaves meet the requirements of the first step, raise the dry bulb temperature to 38°C at a rate of 1°C / h, while controlli...

Embodiment 3

[0046] The smoke loading method of the baking process of the present invention is to make the direction of the tobacco rod the same as the wind direction of the air inlet, such as figure 2 As shown, the post-curing after loading the smoke includes six stages:

[0047] Step 1: After loading the tobacco leaves into the furnace, ignite the fire, raise the dry bulb temperature to 36°C within 4 hours, and control the wet bulb temperature at 34°C, and then stabilize the temperature for 8 hours, so that the tip of the tobacco leaves will turn yellow by 3 cm, and the leaves will sweat. soft. The goal of this stage is to warm and sweat the tobacco leaves just loaded into the barn, create a humidity environment for the tobacco leaves to turn yellow, and prevent the tobacco leaves from "hard and yellow".

[0048] Step 2: When the changes of the tobacco leaves meet the requirements of the first step, raise the dry bulb temperature to 38°C at a rate of 1°C / h, while controlling the wet bu...

Abstract

The invention relates to a bulk-curing-bam curing method for improving curing quality of K326 tobacco. According to the method, the tobacco placing mode is changed in an airflow downdraft type bulk curing bam, the temperature is gradually increased, and the humidity is controlled, so that the temperature and the humidity can be precisely controlled, the uniformity of the tobacco in placing can be improved as well as the flowing smoothness of the airflow, the temperature difference in each position in the curing bam is reduced, the yellowing time of the tobacco in the whole curing bam is reduced, the dehydration rate of the tobacco in the color fixing stage is increased, the time of curing the tobacco is reduced on the whole, the ratio of dreg lamina generating, dust sticking and green tobacco lamina can be reduced, and as a result, the curing quality of the whole K326 tobacco in curing can be improved.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco preparation, and in particular relates to a dense curing barn curing method for improving the curing quality of K326 variety tobacco leaves by changing the way of loading tobacco to carry out gradient temperature rise and humidity control. Background technique [0002] Tobacco curing is the key to flue-cured tobacco production. The K326 variety has obvious aroma characteristics, outstanding style, good aroma quality, sufficient aroma, high industrial usability, and plays an important role in cigarette formulations, and is favored by cigarette companies. However, there are many problems in the K326 variety, such as poor baking resistance, not easy to fix the color, prone to problems such as bad flakes, hanging gray, light color, and low oil content, which affect the promotion and industrial application of K326. [0003] The currently popularized baking process in dense barns is a genera...
