Preparation method for effectively improving famous sun-cured tobaccos

Abstract

The invention aims to provide a preparation method for effectively improving famous sun-cured tobaccos. The method includes procedures of harvesting tobacco leaves, classifying fresh leaves, stringing and racking the leaves, airing the leaves on racks and dewatering until withering and yellowing, spreading and shading in the sun for drying and color fixing, spreading and ground drying in the sun for drying of leaves and veins, storing in the open air and piling up for mellowing. The preparation method for effectively improving famous sun-cured tobaccos has the advantages that technical control is started from harvesting of tobacco leaves to control tobacco leaf harvesting maturity, fresh leaf classification and leaf stringing density, temperature and humidity in a curing house are controlled by covering and uncovering plastic films on two sides of the curing house, watering the ground for humidifying, covering sun-shading screens, adjusting tobacco rope distance and the like, and accordingly problems of overhigh water loss speed of the tobacco leaves, incompleteness in withering and yellowing, overhigh humidity, excessive yellowing of the tobacco leaves or the like can be avoided. Moreover, the preparation method for effectively improving famous sun-cured tobaccos is technically simple and convenient, stable, reliable and easy to control, and economic benefit is increased while high-quality tobacco production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of sun-cured tobacco preparation, and in particular relates to a preparation method capable of effectively improving the quality of sun-cured tobacco. Background technique [0002] As the contradiction between smoking and health has attracted people's attention, it has become a general trend to develop low-tar mixed cigarettes and tobacco "harm reduction and tar reduction". Famous sun-cured tobacco belongs to a kind of endemic light-colored sun-cured tobacco. It has a unique flavor and is similar to flue-cured tobacco. It can be widely used in the formulations of various cigarette products such as flue-cured tobacco, mixed type, and cigar type. And "reducing harm and reducing focus" has a positive effect. Curing is the final link that determines the usability of tobacco leaves. It is to fully reveal and bring out the excellent characteristics of sun-cured tobacco formed and accumulated in the entire agronom...

AI Technical Summary

Problems solved by technology

The tobacco leaves after withering and turning yellow are spread directly on the soil drying ground for exposure. Due to reasons such as high ground humidity, poor ventilation, and poor moisture drainage, the tobacco leaves are dark in color, dark in luster, rich in variegation, and low in quality.

It is difficult to produce high-quality sun-cured tobacco with light color, less variegation, rich oil content, rich aroma and bright luster required by the cigarette industry enterprises by traditional modulation methods. To develop a sun-cured tobacco modulation method that is easy to operate, meets the needs of the cigarette industry, and has good usability The method is an inevitable requirement to improve the quality of sun-cured tobacco, and it is a key technology to solve the sustainable development of sun-cured tobacco.
