Curing method of [Honghua Dajinyuan] more-rain and low-sun-irradiation tobacco leaves

Abstract

The invention discloses a curing method of [Honghua Dajinyuan] more-rain and low-sun-irradiation tobacco leaves. Conditions in a curing barn are controlled as follows in a curing process: firstly, regulating a dry-bulb temperature to 42 DEG C and a wet-bulb temperature to 38-39 DEG C, and regulating humidity for 12-20h so that the leaves are dehydrated by 25%, the tobacco leaves become soft and collapse and veins become soft; then, regulating the dry-bulb temperature to 37-38 DEG C and the wet-bulb temperature to 37-38 DEG C, preserving moisture and yellowing the leaves for 24-32h, so that theleaves are yellowed by 80-90%; regulating the dry-bulb temperature to 42 DEG C and the wet-bulb temperature to 35-36 DEG C, for 12-14h, so that blue veins of the yellow leaves appear and tips of theleaves become cuddled; and finally, regulating the dry-bulb temperature to 45 DEG C and the wet-bulb temperature to 36 DEG C, for 22-25h, so that yellow veins of the yellow leaves appear and the cuddled tips become coiled. With the application of the curing method provided by the invention, yellowing of the tobacco leaves is accelerated, yellowing time is shortened and color fixing time is shortened in the curing process, a proportion of orange smoke of the cured low-sun-irradiation tobacco leaves is increased, proportions of upper-grade and medium-grade tobacco leaves are increased, and proportions of miscellaneous-color and bad tobaccos are obviously reduced; the cured tobacco is relatively obviously good in economic benefit and test process; and meanwhile, the curing quality of normal tobacco leaves is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of tobacco production and curing, and in particular relates to a method for curing safflower, big, golden, rainy and low-sunshine tobacco leaves. Background technique [0002] In recent years, due to the influence of ecological and climate factors in various tobacco areas, the cultivation technology has not been implemented in place, and some fresh tobacco leaves with poor quality and difficult to be cured will be formed. Through the scientific baking method, the effect of fixing and highlighting the quality can be achieved. [0003] Tobacco leaves with much rain and little sunshine refer to tobacco leaves that have grown and matured in a rainy and less sunny environment for a long time. Most of them are middle and lower tobacco leaves. ;Due to the cloudy and rainy weather, it is not easy to show the yellowing of the leaf surface in the tobacco leaf field, and it is not resistant to roasting during the roas...

AI Technical Summary

Problems solved by technology

[0004] The pigment content of Honghua Dajinyuan tobacco leaves is higher than that of other varieties. During the curing process, the yellowing is slower and the water loss is faster, which is easy to cause the occurrence of green smoke. Prolonging the yellowing time can solve the problem of yellowing of tobacco leaves to a certain extent. problem, but prolonging the yellowing time will easily lead to excessive consumption of nutrients in tobacco leaves, resulting in black smoke; high temperature and fast roasting can solve the problem of tobacco leaves turning yellow and fixing color, but the contents of tobacco leaves are not fully transformed after roasting, and the aroma quality and aroma quality are poor. Intrinsic quality is poor
