A tobacco leaf preparation method based on a fruit and vegetable drying room, tobacco leaves and its application

Abstract

The invention discloses a tobacco leaf preparation method, tobacco leaves and application based on a fruit and vegetable drying room. The tobacco leaf preparation method includes harvesting fresh flue-cured tobacco leaves suitable for ripening; weaving the tobacco leaves into a fruit and vegetable drying room; roasting the furnace-loaded tobacco leaves through nine consecutive stages of roasting to obtain the roasted tobacco leaves. The tobacco leaf is the tobacco leaf obtained by the tobacco leaf preparation method. The application is the application of the tobacco leaves obtained by the tobacco leaf preparation method in the preparation of cigarettes. According to the characteristics of the fruit and vegetable drying room, the present invention regulates by precisely controlling the heating rate, temperature and humidity setting point and temperature stabilization time of each stage, and observing the changes of tobacco leaves in each stage. Compared with the traditional three-stage flue-cured tobacco method , easy to operate, flexible to adjust, and the cost of curing is reduced by 0.25 yuan / kg, the cost of inferior tobacco is reduced by 1.46%, and the average price is increased by 0.85 yuan / kg. Roast cost and other issues.

Description

technical field [0001] The invention belongs to the technical field of tobacco leaf preparation, and in particular relates to a fruit and vegetable drying room-based tobacco leaf preparation method, tobacco leaves and applications, which are simple in operation, flexible in adjustment, and can significantly reduce the curing cost of flue-cured tobacco and the proportion of inferior tobacco. Background technique [0002] With the further advancement of tobacco infrastructure construction, major changes have taken place in tobacco curing houses and processes. On the one hand, the traditional roasting process has high labor intensity, unstable roasting effect, low level of automation and intensification, and more and more problems such as serious air pollution, which have become obstacles to the sustainable development of tobacco production; on the other hand On the other hand, whether it is an air-flow ascending or descending roasting house, the capacity of cigarettes is large...

AI Technical Summary

Problems solved by technology

On the one hand, the traditional baking process is labor-intensive, the baking effect is unstable, the degree of automation and intensification is not high, and the problem of serious air pollution is becoming more and more prominent, which has become an obstacle to the sustainable development of tobacco leaf production; on the other hand On the one hand, whether it is a rising or falling air-flow curing barn, the tobacco-filling capacity is large, the quality of fresh tobacco leaves varies greatly, and the curing process is difficult to implement, resulting in serious baking losses. room"), for tobacco farmers with moderate planting scale and messy tobacco leaf maturity, making full use of the existing fruit and vegetable drying room to prepare tobacco leaves can not only effectively save the initial investment and later management and maintenance costs of baking settings, but also save Reduce the floor area of ​​the facility, and accurately perform the baking process operation, reducing the loss of baking

However, from the perspective of equipment structure and management and maintenance, because tobacco farmers are accustomed to using the past baking method, and they do not have a good grasp of the structure and baking technology of the fruit and vegetable drying room, the traditional baking method is used in the fruit and vegetable drying room to process tobacco leaves. There are often practical problems such as low quality of tobacco leaf curing and inconspicuous benefits, which restrict the application of fruit and vegetable drying rooms in tobacco leaf preparation
