specific Embodiment

[0008] In the first step, after the tobacco leaves are loaded into the furnace, close the air inlet and exhaust windows in time, and then start ignition. After ignition, the dry bulb temperature is increased to 36-38°C at a rate of 1°C per hour, and the fire is stabilized. , The wet bulb temperature is controlled at 35-36℃, and the temperature and humidity are maintained to make the tip and edge of the bottom tobacco leaf lose water first and become soft and yellow, and prevent the green smoke from being roasted. When the bottom tobacco leaves turn yellow and reach 3-4 yellowing, the second-layer tobacco leaves lose water and wither, and the leaves begin to soften and turn yellow.

[0009] In the second step, the air inlet and exhaust windows are opened about 1 / 3, and the dry bulb temperature is raised to 40-42°C at a rate of 1°C every two hours, and the wet bulb temperature is controlled at 37-38°C. Stabilize the temperature, maintain this temperature and humidity, and promote th...

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 roasting technology. technical background [0002] Tobacco is an economic crop for leaves. Fresh tobacco leaves contain 80%-90% of water. They must be placed in special equipment. The temperature and humidity are artificially controlled to make them yellow and dry, and the various fine substances formed in the leaves are fixed. Only when it comes down can it become a raw material for 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 Press / Gong Changrong, etc. / 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 implemented the three-stage curing ...
