Fuente: WIPO "tobacco agriculture" The invention discloses a high-efficiency baking method for improving appearance quality of K326 variety of tobacco leaves. The method is characterized by baking by using biomass fuel, harvesting properly mature K326 variety of tobacco leaves; arranging rods into a baking room to be baked, wherein the yellowing period control comprises initial yellowing period control, middle yellowing period control and later yellowing control, the color fixing period control comprises the initial color fixing stage and the later color fixing stage, and the initial color fixing stage control comprises temperature rise in the rate of 1 DEG C/1-2h after the yellowing period control is finished; and the stem drying stage control comprises rising the temperature of a dry bulb to 66-67 DEG C, and adjusting thetemperature of a wet bulb to 40-42 DEG C. Through the slow temperature rise at the early color fixing stage, the problems that the grey smoke hanging and process execution are inaccurate, the bakingtime is long, the combustion efficiency is low, the pollution is large, and the feeding is frequent since the yellowing is easy and the color fixing is difficult, the tobacco leaves after baking are stiff, the fragrance is not enough, the temperature rise is slow, and the stable temperature is unstable in the traditional K326 tobacco leaf baking process are solved by combining the high temperatureand low humidity at the stage of drying the stems, and the proportion of the tobacco in middle and high quality and the quality of the baked tobacco leaves are obviously improved.
