Baked tobacco upper tobacco leaf with stem cutting collecting bulk baking method and baking structure

Abstract

The invention discloses a baked tobacco upper tobacco leaf with stem cutting collecting bulk baking method and a baking structure. When 4-6 pieces of upper tobacco leaves are fully mature, 4-6 leavesare cut and connected with stems at one time and then are directly erected and stacked on an air separation plate in an airflow falling leaf baking room for baking, which not only improves the harvesting maturity of the tobacco leaves and the time of baking and yellowing, but also coordinates the inner quality of the upper tobacco leaves, and the tobacco leaf breaking is solved in the tobacco weaving process with the stems. According to the method, since the leaves are still born on the stems, the leaves can be provided with good support during the baking process of the bulk leaf tobacco baking process with the stems, and a windward environment is formed in the airflow falling leaf baking room to promote the improvement of the baking quality of the upper tobacco leaves. The method has theadvantages of simple operation of packing tobaccos and lower baking and obvious labor saving, the smoke volume of the baking room is increased by 30-40%, there is the support of the stems, the tobaccoleaves are not easy to fall during the baking process, the ventilation and drainage environment is better, and after the upper 4-6 leaves are baked, the quality of the tobacco leaves can be significantly improved.

Description

technical field [0001] The invention relates to a method for curing tobacco leaves, in particular to a method and structure for curing tobacco leaves in bulk with stems on top of flue-cured tobacco. Background technique [0002] The upper tobacco leaves are a treasure trove of tobacco leaves that need to be developed urgently. However, due to the thicker tobacco leaves and lower water content, the structure of the upper tobacco leaves after roasting has problems such as stiffness, ash, and more variegated colors, making it difficult to roast. At present, the main method of harvesting and roasting the upper tobacco leaves is roasting with slices and braided rods. The proportion of tobacco leaves after roasting in this way is more than 10% stiff and ash-hanging. The existing large-scale intensive curing barns can produce 500 dry tobacco per barn. ~600 kg, calculated according to 10% ash and stiffness ratio. If no ash and stiffness appear, the grade of this part of tobacco leav...

Problems solved by technology

[0004] The first object of the present invention is to provide a method of bulk-curing the upper part of flue-cured tobacco with stems, which can reduce the proportion of ash and stiffness of the upper part of the cured tobacco leaves, and at the same time avoid the existing problems in the cutting and binding rod curing technology. The technical defects such as falling off of the upper
