specific Embodiment approach

[0019] As can be seen from Table 1, the process steps of the present invention mainly include three baking stages of yellowing stage, color fixing stage and gluten drying stage, which are divided into five major steps. Humidity control steps, two key temperature and humidity control steps in the color fixing stage, and one key temperature and humidity control step in the gluten drying stage. In actual operation, you only need to operate according to the control conditions in the table. In detail, it is:

[0020] The first step of the yellowing stage:

[0021] Operation requirements: After loading the tobacco leaves into the furnace, close the doors, windows and air inlets, ignite the fire, raise the dry bulb temperature to 38-39°C within 5 hours, and control the wet bulb temperature at 37-38°C at the same time, stabilize the temperature for 8-12 hours, so that the tobacco leaves The blades turn yellow by 40-50%, the fan runs at low speed, and the fan with frequency conversion ...

Abstract

The invention discloses a three-section and five-step bulk curing process for flue-cured tobacco, and belongs to the technical field of tobacco modulation. The process mainly comprises three curing stages, namely a yellowing stage, a fixation stage and a stem drying stage, and is characterized in that: the yellowing stage and the fixation stage are also decomposed into two key temperature and humidity steps respectively; by increasing a key temperature and humidity step of the stem drying stage, three curing stages and five key temperature and humidity steps are set for the entire curing process; according to variation condition of tobacco leaves and by controlling the temperature and humidity of a curing room in the temperature and humidity ranges required by corresponding steps of the five key temperature and humidity steps, the aim of adjusting and controlling flue-cured tobacco curing process is fulfilled, a better effect is achieved, poor curing of green miscellaneous tobacco and the like is obviously reduced, the proportion of yellow tobacco and high-grade tobacco is increased, the structure is loose, the oil content is increased, and the internal and external appearance quality and the availability of the tobacco are obviously 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 a dense barn for loading tobacco in a hanging rod mode or a tobacco clip mode. 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. In recent years, with the development of three modernized production and the popularization and application of intensive baking equipment, the quality of field fresh tobacco leaves and baking equipment have been significantly improved. At present, the area of ​​tobacco leaves baked in intensive curing rooms h...
