specific Embodiment

[0008] In the first step, after the tobacco leaves are loaded into the furnace, close the air inlet tunnel and the exhaust window in time, and then start to ignite. Temperature, wet bulb temperature is controlled at 35--36 ℃, maintain this temperature and humidity, so that the tip and leaf edge of the bottom tobacco leaves lose water first, become soft and yellow, and prevent the green smoke from being baked. When the bottom layer of tobacco leaves turns yellow to 3--4 percent yellow, the second layer of tobacco leaves loses water and withers until the leaves start to soften and turn yellow.

[0009] In the second step, open the wind tunnel and the exhaust window by about 1 / 3, and increase the temperature of the dry bulb to 40-42°C at a rate of 1°C every two hours, and control the temperature of the wet bulb to 37-38°C. Press the fire to stabilize the temperature, maintain this temperature and humidity, and promote the tobacco leaves to fully lose water, wither and become soft...

Abstract

A process for baking tobacco leaves by 5 steps in 3 stages divided according to temp, humidity and the open degree of window and tunnel is disclosed. Its advantages are high quality of baked tobacco leaves and high operatability.

Description

technical field [0001] The invention relates to a tobacco leaf curing technology. technical background [0002] Tobacco is an economic crop for leaves. Fresh tobacco leaves contain 80% - 90% moisture. They must be placed in specific equipment to turn yellow and dry by artificially controlling the temperature and humidity conditions, so as to remove various fine substances formed in the leaves. Only when it is fixed can it become the raw material of the cigarette industry. This process is called flue-cured tobacco. According to the introduction of "Three-stage Curing of Flue-cured Tobacco and Its Supporting Technology" (Science and Technology Literature Publishing House / Gong Changrong et al. / May 1996), the environmental factors of flue-cured tobacco mainly include temperature, humidity and ventilation, and the three influence each other. The comprehensive effect plays an important role in the baking quality. Since the 1990s, my country has fully impleme...
