Embodiment 1

[0022] (1) For the fresh tobacco leaves at the lower part of the sun-yellow smoke Yunshai No. 1 with the same maturity in the field, use conventional fence drying or shed drying to make the tobacco leaves 60% to 70% yellow, so that the tobacco leaves wither and turn yellow;

[0023] (2) Put the tobacco leaves in step (1) into a conventional flue-cured furnace, raise the temperature to 36-38°C after 5 hours, control the wet bulb temperature to 36-37°C, keep the temperature stable for 2-4 hours, and bake the tobacco leaves to 7-38°C 80% yellow;

[0024] (3) Raise the dry bulb temperature to 40-42°C at a rate of 1°C in 2 hours, control the wet bulb temperature at 37-38°C, keep the temperature stable for 2-4 hours, and roast the tobacco leaves to 80-90% yellow;

[0025] (4) Raise the temperature of the dry bulb to 45-48°C at a rate of 1°C in 2 hours, control the temperature of the wet bulb at 37-38°C, keep the temperature stable for 2-4 hours, and roast the tobacco leaves until th...

Embodiment 2

[0029] (1) For the fresh tobacco leaves in the middle of Sun-Yellow Yanyan Yunshai No. 1 with the same maturity in the field, the tobacco leaves will be 60% to 70% yellow by conventional sun-drying, so that the tobacco leaves will wither and turn yellow;

[0030] (2) Put the tobacco leaves in step (1) into a conventional flue-cured furnace, raise the temperature to 36-38°C after 5 hours, control the wet bulb temperature to 36-37°C, keep the temperature stable for 2-4 hours, and bake the tobacco leaves to 7-38°C 80% yellow;

[0031] (3) Raise the dry bulb temperature to 40-42°C at a rate of 1°C in 2 hours, control the wet bulb temperature at 37-38°C, keep the temperature stable for 2-4 hours, and roast the tobacco leaves to 80-90% yellow;

[0032] (4) Raise the temperature of the dry bulb to 45-48°C at a rate of 1°C in 2 hours, control the temperature of the wet bulb at 37-38°C, keep the temperature stable for 2-4 hours, and roast the tobacco leaves until they are all yellow an...

Embodiment 3

[0036] (1) The fresh tobacco leaves on the upper part of the yellow sun-dried tobacco Yunshai No. 1 with the same maturity are harvested in the field, and the tobacco leaves made by conventional shed sun-dried tobacco leaves reach 60% to 70% yellow, so that the tobacco leaves wither and turn yellow;

[0037] (2) Put the tobacco leaves in step (1) into a conventional flue-cured furnace, raise the temperature to 36-38°C after 5 hours, control the wet bulb temperature to 36-37°C, keep the temperature stable for 2-4 hours, and bake the tobacco leaves to 7-38°C 80% yellow;

[0038] (3) Raise the dry bulb temperature to 40-42°C at a rate of 1°C in 2 hours, control the wet bulb temperature at 37-38°C, keep the temperature stable for 2-4 hours, and roast the tobacco leaves to 80-90% yellow;

[0039] (4) Raise the temperature of the dry bulb to 45-48°C at a rate of 1°C in 2 hours, control the temperature of the wet bulb at 37-38°C, keep the temperature stable for 2-4 hours, and roast t...

Abstract

The invention relates to a preparation method for curing and setting the color and dry gluten period of Yunnan characteristic sun-dried tobacco varieties, belonging to the technical field of sun-dried tobacco preparation. For fresh tobacco leaves with the same maturity in the field, the sun-cured tobacco leaves reach 6 to 70% yellow and then bake to set the color and dry tendons. The traditional bar-dried three stages: withering and yellowing period, fixed color and dry leaf period, dry tendon bleaching The period is shortened to two stages, that is, the period of withering and yellowing in the sun, and the period of drying the gluten after baking. Among them, the period of curing and setting the color and drying tendons is when the tobacco leaves reach 6-70% yellow, the tobacco leaves become soft, and are baked on the kang, the tobacco leaves turn 8-90% yellow to fix the color, and finally bake and dry the tendons. The present invention has the advantages of significantly shortened brewing time, small footprint, reduced labor, overcoming the influence of excessive rain in the later stage of brewing, that is, it is not easily affected by external environmental factors, and the content of TSNAs is significantly reduced, ensuring the sensory quality and physical properties of sun-cured yellow tobacco. and chemical quality.

Description

technical field [0001] The invention relates to a preparation method for curing and setting the color and dry gluten period of Yunnan characteristic sun-dried tobacco varieties, belonging to the technical field of sun-dried tobacco preparation. Background technique [0002] Sun-cured tobacco is a unique type of tobacco leaf in my country. It has a planting history of hundreds of years. After long-term natural selection and artificial cultivation, many famous and high-quality sun-cured tobacco with unique flavor characteristics and different quality styles have been formed. If it is developed and utilized to produce a new generation of Chinese-style low-tar safe cigarettes with diverse styles, it will not only make full use of my country's rich sun-cured tobacco resources, but also change the production and sales structure of single flue-cured tobacco in my country and increase the source of national fiscal revenue. Moreover, it can open up a new development path for my countr...
