Method for selecting wet bulb temperature in yellowing period of flue-cured tobacco baking process

Abstract

The invention discloses a method for selecting wet bulb temperature in a yellowing period of a flue-cured tobacco baking process. The method includes establishing a yellowing period wet bulb temperature judgment model about fresh tobacco leaf index parameters; harvesting a plurality of to-be-detected tobacco leaves in the same field, measuring index parameters of the to-be-detected tobacco leaves, calculating average values of the index parameters, substituting the average values of the index parameters of the to-be-detected tobacco leaves into the judgment model in the step S1, and determining the key point wet bulb temperature in the yellowing period of the tobacco leaves. The index parameters of the tobacco leaves comprise a moisture content value, a chlorophyll content value, a thickness value, a leaf base branch vein width value and a length-width ratio. According to the method, the judgment model is established by selecting specific tobacco leaf index parameters, a unified standard is provided for selecting the wet bulb temperature when different varieties of tobacco leaves are baked, baking personnel can obtain the most suitable wet bulb temperature condition in the yellowing period only by measuring a plurality of simple parameter data, the problems of insufficient hardening and yellowing due to water loss or baking due to excessive water loss and the like caused by wrong selection of wet bulb temperature are avoided, and the economic characters of the tobacco leaves baked under the condition are obviously improved.

Description

technical field [0001] The invention belongs to the field of quality evaluation of fresh tobacco leaves and specifically designs a method for selecting the wet bulb temperature in the yellowing period of the flue-cured tobacco curing process. Background technique [0002] During the conditioning of tobacco leaves, the complex physiological and biochemical changes inside the leaves are all carried out with water as the medium. Different temperature and humidity conditions affect the water loss of tobacco leaves and ultimately affect the biochemical process. The wet bulb temperature can better reflect the moisture status in the barn and the physiological reaction temperature of tobacco leaves, so the wet bulb temperature in the barn is an important factor affecting the quality of tobacco leaves. [0003] At present, the setting of the wet bulb temperature of tobacco leaves is mostly within the appropriate wet bulb temperature range of each stage stipulated in the technical spe...

Problems solved by technology

However, this invention does not study the relationship between tobacco leaf weight, aspect ratio, thickness, main vein width at the base of the leaf and the wet bulb temperature at each stage of the tobacco leaf yellowing period.
