Embodiment Construction

[0018] The implementation of the present invention will be described below in conjunction with detailed process steps.

[0019] Baking process of the present invention mainly comprises five key stages:

[0020] Step 1: After loading the tobacco leaves into the furnace, close the doors, windows and air inlets, ignite the fire, raise the dry bulb temperature to 37-38°C within 5 hours, and control the wet bulb temperature at 37°C at the same time, and stabilize the temperature for 8-12 hours to make the tobacco leaves become 3-40% yellow, the leaves begin to lose water and wither;

[0021] Operation requirements: Tobacco leaves are fresh tobacco leaves that have reached a suitable maturity in the field. The goal of this stage is to preheat the tobacco leaves, turn the tip of the tobacco leaves yellow, and lose water moderately. Generally, this stage does not drain moisture and is the moisturizing and yellowing stage.

[0022] Step 2: When the change of tobacco leaves meets the r...

Abstract

The invention discloses a bulk curing process for cured tobacco K326. In the process, on the basis of the traditional three-stage curing, the curing stage is detailed into five stages, wherein the main yellowing temperature in curing is increased by 1 to 2 DEG C, while the wet bulb temperature in a later yellowing stage and an early color fixing stage is reduced by 1 to 2 DEG C. The process combines qualitative description and quantitative index, is scientific and practical, easy and safe to operate and has strong operability, can remarkably reduce rotten tobacco and soot attached tobacco and increase the color and oil content of the tobacco. By the process, the curing quality of the tobacco is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of flue-cured tobacco preparation, and in particular relates to a dense barn curing process of K326 variety. Background technique [0002] In the production of flue-cured tobacco, varieties and cultivation are the foundation, and baking is the key. The K326 variety has obvious aroma characteristics, outstanding style, good aroma quality, sufficient aroma, high industrial usability, and plays an important role in cigarette formulations, and is favored by cigarette companies. However, the K326 variety has poor roasting resistance and is not easy to fix the color. After roasting, the tobacco leaves are prone to problems such as bad flakes, hanging ash, light color, and low oil content, which affects the popularization and industrial use of K326. At present, the National Tobacco Administration of China promotes the use of dense curing barn baking technology, which is a universal technical specification. Some pr...
