Abstract

The invention relates to a method for baking tobacco leaves of a honghua dajinyuan (Chinese character) variety by use of a closed tobacco curing barn, and belongs to the technical field of tobacco leaf processing. The method comprises the following steps: a yellowing stage, a leaf-drying stage and a stem-drying stage; at the yellowing stage, putting the tobacco leaves into the closed tobacco curing barn, baking the tobacco leaves with a dehumidifying heat pump, and heating the tobacco leaves at the temperature rise rate of 1-2 DEG C / h until the dry bulb temperature is 33-36 DEG C and the wet bulb temperature is 30-35 DEG C, and keeping for 20-25 hours until over 40% of tobacco leaves at a top table turn yellow; heating the tobacco leaves at the temperature rise rate of 0.5-1.5 DEG C / h until the dry bulb temperature is 37-39 DEG C and the wet bulb temperature is 32-36 DEG C and keeping for 20-30 hours; and heating the tobacco leaves at the temperature rise rate of 0.5-1 DEG C / h until the dry bulb temperature is 42-43 DEG C and the wet bulb temperature is 33-36 DEG C and keeping for 16-20 hours until the tobacco leaves turn yellow. The method has the beneficial effects that the baking time of the honghua dajinyuan can be effectively shortened; the baked green tobacco is avoided; the ratio of variegated tobacco and withered tobacco of the honghua dajinyuan is effectively reduced; the mould phenomenon of the tobacco leaves can be avoided.

Description

technical field [0001] The invention belongs to the technical field of tobacco leaf processing, and in particular relates to a method for roasting safflower and gold variety tobacco leaves in a closed tobacco curing room. Background technique [0002] In the production of flue-cured tobacco, curing is the last important link that determines the quality of tobacco leaves, and it is also the weakest link in China's tobacco leaf production at present, which directly affects the sustainable development of tobacco leaves in my country. The curing quality of tobacco leaves is mainly restricted by the quality of fresh tobacco leaves, curing equipment and curing technology. [0003] Honghua Dajinyuan was originally named Lumeiyiyan. In 1962, tobacco farmers in Lumeiyi Village, Lunan County, Yunnan Province selected it from the mutant strain of Dajinyuan. It was named because of its deep red flower color. It is one of the main cultivated varieties in Yunnan Tobacco Area. one. As a ...
