Three-stage six-step baking technology for flue-cured tobacco in common flue-curing barn

Abstract

The invention discloses a three-stage six-step baking technology for flue-cured tobacco in a common flue-curing barn, and belongs to the technical field of modulation of flue-cured tobacco. The technology mainly comprises three baking stages, namely a yellowing stage, a color fixing stage and a stem drying stage. The technology is characterized in that: the yellowing stage comprises three key temperature and humidity steps; the color fixing stage comprises two key temperature and humidity steps; and the stem drying stage has a key temperature and humidity step. The whole braking process has the three baking stages and the six key temperature and humidity steps, and the temperature and the humidity in the flue-curing barn are controlled in the temperature and humidity ranges required by the corresponding steps of the six key temperature and humidity steps according to the change conditions of tobacco leaves, so that the aim of regulating and controlling the baking process of the flue-cured tobacco is fulfilled, a good effect is achieved, the destroyed tobacco such as green impure tobacco and the like is obviously reduced, the proportion of orange tobacco and high-grade tobacco is improved, the flue-cured tobacco has a loose structure, the oil content of the flue-cured tobacco is increased, and the inner and outer view quality and the availability of the tobacco leaves are remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco preparation, and in particular relates to a baking process in an ordinary barn for loading tobacco by hanging rods. Background technique [0002] In the production of flue-cured tobacco, curing is the last important link that determines the yield and quality of tobacco leaves. It is also the weakest link in China's tobacco leaf production, 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. At present, there are mainly two types of baking equipment in my country: intensive curing barns and ordinary curing rooms. In recent years, although intensive curing rooms have been widely promoted, ordinary curing rooms still undertake the baking task of 30-40% of the national tobacco planting area. Therefore, , The quality of toba...

Problems solved by technology

[0004] In order to solve a series of problems caused by the above-mentioned three-stage five-step tobacco curing process due to the high starting temperature and color-fixing temperature, the present invention provides a three-stage six-step common roasting method with relatively low starting temperature and color-fixing temperature. To solve the problem of supporting the baking process of ordinary barns with tobacco hanging on rods, and improve the quality and economic benefits of tobacco leaves
