| titleOfInvention | Method for removing mildew from tobacco leaves mildewed in alcoholization period |
| abstract | The invention discloses a method for removing mildew from tobacco leaves in an alcoholization period, which comprises the following steps of introducing ozone into a sealed tobacco leaf stack for treating mildew, wherein the ozone treatment is divided into two stages: in the first stage, ozone is introduced at a concentration of 20-500 ppm every day, and the treatment is carried out for 10-30 days; in the second stage, introducing 5-100 ppm of ozone until the tobacco mellowing stage is finished; then, introducing nitrogen and ozone at the same time from the end of the alcoholization period to the stage of stack opening use of the tobacco leaves, wherein the introduced nitrogen finally reduces the oxygen concentration in the sealed tobacco leaf stack to below 2 percent, and the concentration of the introduced ozone is 1-10 ppm; the method effectively solves the problems of tobacco leaf surface wind mildew and the like in the storing and curing process of tobacco leaves in the alcoholization period, does not influence the normal alcoholization of the tobacco leaves, and realizes the maintenance of the fragrance and the smoking taste of the mildewed tobacco leaves; the tobacco leaves are in ideal color, the utilization rate of the mildewed tobacco leaves is increased, and the tobacco leaf loss and economic loss caused by the mildewing of the tobacco leaves are reduced. |
