Problems solved by technology

[0004] The currently popularized three-stage curing process refers to dividing the entire process of curing tobacco leaves into three stages corresponding to the appearance state of tobacco leaves and the temperature and humidity requirements according to the changes in the appearance characteristics of tobacco leaves and the internal organic connection, that is, the yellowing stage. , color fixing stage and gluten drying stage are mainly a set of corresponding baking parameters summarized by ordinary curing barns and conventional varieties of tobacco leaves. The curing characteristics of Yuyan No. 7 lead to the unsatisfactory curing quality of Yuyan No. 7 tobacco leaves, with many veins and hanging ash, and the yield, quality and economic benefits are far from the expected effects of the variety.

Embodiment 1

[0039] Use 5HR-160 fruit and vegetable drying equipment (i.e. heat pump dense air flow descending barn) to roast the mature and harvested middle leaves of Yuyan No. 7, and the tobacco leaves hanging on the high place are the upper shed tobacco, that is, the high-temperature layer Tobacco leaves, the tobacco leaves hanging in the lower place are the lower shed tobacco, that is, the low-temperature layer tobacco leaves, combined with the attached figure 1 ,Specific steps are as follows:

[0040] 1) In the early stage of yellowing, put the tobacco leaves on the kang and ignite the fire, raise the dry bulb temperature to 36°C at a rate of 2°C / h, keep the wet bulb temperature at 34°C, then bake for 16 hours, and set the operation mode of the barn damper to moisturizing , so that the tobacco leaves are fully sweated until the tip of the tobacco leaves in the upper shed turns yellow.

[0041] 2) In the middle stage of yellowing, raise the dry bulb temperature to 38°C at a rate of 1°C / ...

Abstract

The invention belongs to the technical field of three-stage roasting of tobacco leaves, and particularly relates to a bulk roasting method capable of reducing surface dusting and blackening of tobacco leaves of Yuyan #7 and application of the bulk roasting method. A heat pump bulk roasting room is used, and a method of eliminating moisture in time, carrying out moisture elimination and roasting at the same time, controlling wet balls and continuously eliminating moisture is adopted; therefore, the problems that moisture in the tobacco leaves of Yuyan #7 is difficult to eliminate, main veins are difficult to dry, surface dusting is easily caused during heating and the leaves are easy to blacken are effectively solved.

Description

technical field [0001] The invention belongs to the technical field of three-stage curing of tobacco leaves, and in particular relates to an intensive curing method for reducing ash and black grains of Yuyan No. 7 tobacco leaves and its application. Background technique [0002] Luzhou-flavor tobacco leaves have the characteristics of rich flavor and sufficient oil content, which is of great significance to the construction of the core raw material system of Chinese-style cigarettes. Due to the special natural conditions and ecological characteristics, the tobacco leaves produced in the Henan tobacco area have a strong aroma style. However, in recent years, due to the single variety, degraded species, and large-scale outbreak of devastating diseases, the characteristics of the strong-flavor tobacco leaves in Henan Province have been weakened, which can no longer meet the needs of cigarette industry companies for leaf group formulations. [0003] Yuyan No. 7 is a new Luzhou-...
