Description

Technical Field

[0001] The utility model relates to the technical field of tobacco leaf baking, in particular to a closed baking room used for tobacco leaf baking. Background Art

[0002] Tobacco leaf baking is a tobacco leaf curing method that adjusts the temperature and humidity of the baking room through heating and ventilation measures in a special baking room. The same variety, the same part, and the same maturity of tobacco leaves are sent to the baking room through braided poles and loaded with tobacco, and the temperature and humidity are controlled according to the quality of the tobacco leaves. Generally, the leaves lose water and wither at 35~38℃, and turn yellow in large quantities; the leaves basically turn yellow and completely wither at 41~42℃, and the main veins become soft; at 46~48℃, yellow sheets, yellow tendons, and small rolls are reached; at 54~55℃, large rolls are reached. Normal tobacco leaves are mainly baked in three stages (i.e. yellowing, color fixing, and dry tendons). The yellowing stage is to make the tobacco leaves yellow and soft, the main veins become soft, starch and protein are hydrolyzed, soluble sugars and organic acids increase, ammonia and miscellaneous tastes are lost, and the nicotine content is reduced; the color fixing stage is to dry the leaves, fix and maintain the existing color and quality, and reach yellow sheets and yellow tendons; the dry tendon stage is to dry the main veins of all tobacco leaves. At the end of baking, the moisture content of tobacco leaves is 14% to 16%, and the whole baking process takes about 4 to 5 days. Improper baking will cause quality defects such as green tips, green wings, ash, veins, and fiery red.
