Embodiment

[0025] The first step: using Yunyan 85 as the material, the upper leaves after harvesting are first sorted into stalks, and then the tobacco leaves behind the stalks are piled up into stacks, with the tip of the leaf facing inward and the petiole facing outward. 80cm, the bottom is padded with burlap, the surrounding and the top of the pile are sealed with burlap, and a thermometer is placed in the center of the pile to keep the temperature between 30-40°C. When the temperature in the pile exceeds 45°C, turn the pile in time. Adjust the upper layer to the middle layer, the middle layer to the lower layer, and the lower layer to the upper layer, until the tobacco leaves turn 90% yellow, hang them in the barn for baking.

[0026] Step 2: Ignition and temperature control: After ignition, raise the dry bulb temperature to 36°C at a heating rate of 2°C / h, and keep the wet bulb temperature at 34°C. After all the tobacco leaves are softened, enter the next stage of curing.

Abstract

The invention discloses a baking method of upper leaves of flue-cured tobaccos. The baking method belongs to the technical field of tobacco baking. The baking method comprises the following steps of: enabling upper leaves collected from fields to be weaved into rods and packed for cover, keeping a temperature to be 30-40 DEG C until 90-100% of tobacco leaves turn yellow, hanging the tobacco leaves in a curing barn for baking; after lighting, rising dry-bulb temperature to be 36-37 DEG C at a rising speed of 1-3 DEG C / h, keeping a wet bulb temperature to be 34-35 DEG C until blades of the tobacco leaves are totally softened, then conducting treatment in a yellowing stage, a color fixing stage and a stem drying stage until ribs of the tobacco leaves are totally dried. The baking method can solve a problem that material conversion is insufficient in a baking process of the upper leaves, the tobacco leaves after baking is heavy in miscellaneous gas, smoke is rough and thrill is big is solved, baking time can be appropriately shortened during modulation, baking efficiency is promoted, and baking energy is saved.

Description

technical field [0001] The invention belongs to the technical field of tobacco curing, in particular to a method for curing the upper leaves of flue-cured tobacco. Background technique [0002] Curing modulation is an important link to determine the quality and usability of tobacco leaves. Fresh tobacco leaves with potential quality can only show their excellent quality through the roasting process. In addition, fresh tobacco leaves with the same potential can also be formed through different curing processes. Tobacco leaves of different qualities. Because of this, for fresh tobacco leaves with different potentials, it is necessary to adopt suitable baking process measures to obtain high-quality tobacco leaves to the greatest extent. [0003] The upper leaves are at the top of the tobacco plant, with good ventilation and light transmission conditions, and strong photosynthesis. At the same time, they take nutrients from the middle and lower leaves, accumulate a lot of dry m...
