A method of intensive roasting to reduce ash hanging on upper leaves of k326

Abstract

The invention discloses an intensive roasting method for reducing ash hanging on upper leaves of K326, and belongs to the technical field of tobacco leaf roasting. The present invention raises the dry bulb temperature by 40-42°C in the early stage of yellowing, promotes the dehydration of leaves by 30% in advance, realizes the collapse of tobacco leaves, and the softening of branch veins, and then drops to 36°C. Pay attention to moisturizing and yellowing, and the dry-wet difference does not exceed 1°C , others are baked according to the conventional process. During the entire baking process, as long as the tobacco leaves wither and collapse and the branch veins become soft at the early stage of yellowing, and combined with moisturizing and yellowing, it will promote the transfer of moisture from the veins of the tobacco leaves to the mesophyll in advance, accelerate the softening of the veins, and make the leaves fully mature in the late stage of yellowing. Withering and collapse, the main veins become soft, so as to realize the partial water loss balance between the veins and the mesophyll, and avoid the moisture in the tobacco leaves being forced out as the temperature rises in the later stage of yellowing and early stage of color fixation, resulting in a large amount of ash-hanging smoke. The invention has strong operability, is scientific and practical, can obviously reduce hanging ash smoke, and significantly improve the quality of tobacco leaf curing.

Description

technical field [0001] The invention belongs to the technical field of tobacco leaf curing, and in particular relates to an intensive curing method for reducing ash on the upper part of K326 leaves. Background technique [0002] There are many factors that lead to ash on tobacco leaves during the curing process. From the perspective of fresh tobacco quality, the main manifestations are: upper tobacco leaves, dry tobacco leaves, autumn tobacco leaves, high-oil content tobacco leaves, black burst smoke, over-ripe or immature tobacco and other dehydration characteristics. Poor tobacco leaves; from the perspective of curing measures, the main manifestations are: excessive heating or cooling, excessive ventilation and humidification, excessive yellowing and other measures that easily cause dehydration and imbalance of tobacco leaves; and uncoordinated dehydration of tobacco leaves usually leads to ash hanging From the late yellowing period to the early stage of color fixing, the ...

AI Technical Summary

Problems solved by technology

[0005] The current (K326) upper leaf curing process mostly removes moisture from the later stage of yellowing to the early stage of color fixation, but in the actual curing process, it is often difficult for the upper leaf tobacco leaves to lose water, and the water loss cannot meet the requirements within the specified time , when the fire is turned, the leaves are not soft enough, the branch veins are low, and the main veins are hard, which brings difficulties to the color of the tobacco leaves.
