Problems solved by technology

Under the condition of hot air circulation in the normal baking process, increase the yellowing temperature, fix the temperature and keep the moisture in the three periods of leaf yellowing, gluten period, and dry leaf period, extend the baking time three times, and the delay time is 42-60 Hours, promote the decomposition of macromolecular substances such as tobacco leaf starch, and reduce the tobacco leaf starch after roasting. However, in the season when tobacco leaves are harvested and roasted, the single kang baking cycle is too long, which will increase fuel consumption and increase the impact on the environment. Pollution
This curing method does not change the structure of tobacco leaves and the essence of the original three-stage curing process, and it also cannot achieve the purpose of shortening the total duration of single kang curing and reducing starch while fully extending the yellowing period and color fixing period.

Embodiment 1

[0029] Embodiment 1. "Half-leaf" roasting method reduces starch content test of tobacco leaves (Hubei)

[0030] The content of starch in the upper part of the tobacco was high, and the "half leaf" baking was used to investigate the effect on reducing starch.

[0031] Materials and Methods:

[0032] 1.1 Test site: Xiaoguan Town, Xuan'en County, Enshi City, Hubei Province

[0033] 1.2 Test material: Yunyan 87, upper smoke

[0034] 1.3. Processing settings:

[0035] Bake in a downdraft oven with three treatments:

[0036] The complete leaf is along one side of the main tobacco rib, close to the main tobacco rib to divide a complete leaf into two, and bake it on a specially designed special tobacco rod hanging rod, one side without ribs (treatment 1), and the other side with ribs (treatment 2). ). Conventional whole leaf binding and baking (for treatment three).

[0037] Namely: Treatment 1: A1-half leaves are roasted without ribs, and half of dry tobacco leaves are roasted ...

Embodiment 2

[0064] Example 2. "Half-leaf" roasting method to reduce starch content in tobacco leaves (Jia County, Henan)

[0065] 1 Materials and methods:

[0066] 1.1 Test site: Ningxian Songkang House, Jia County, Pingdingshan, Henan Province

[0067] 1.2 Test material: middle smoke 100, upper smoke

[0068] 1.3. Processing settings:

[0069] Bake in a downdraft oven with three treatments:

[0070] The complete leaf is along one side of the main tobacco rib, close to the main tobacco rib to divide a complete leaf into two, and bake it on a specially designed special tobacco rod hanging rod, one side without ribs (treatment 1), and the other side with ribs (treatment 2). ). Conventional whole leaf binding and baking (for treatment three).

[0071] Namely: Treatment 1: A2—half leaves are roasted without ribs, and half of dry tobacco leaves are roasted and terminated;

[0072]Treatment 2: B2 ━ half-leaf roasted with ribs;

[0073] Treatment 3: C2 ━ conventional roasting of the whole...

Abstract

A "half leaf" roasting method for reducing the starch content of flue-cured tobacco is characterized in that: the half leaf harvesting method is adopted, and two "half tobacco leaves" from which the tobacco stems are removed are put on poles for pit roasting, and the roasting process is only It includes three stages: leaf yellowing stage, leaf withering branch yellowing stage, and leaf delayed color-fixing stage. The method for curing tobacco leaves provided by the invention can obviously reduce the starch content of cured tobacco leaves, which is beneficial to reduce the irritation of smoking tobacco leaves after curing, and improve the comfort of tobacco leaves after smoking; It can also shorten the total baking time of a single kang and save precious baking season resources; significantly shorten the baking time, save a lot of baking fuel consumption, and reduce the air pollution of the fuel to the environment; only the leaves enter Roasting in the barn takes up less space in the barn, which greatly increases the capacity of a single kang for cigarettes; half-leaf roasting does not contain tobacco ribs, and the tobacco leaves do not need to be threshed after roasting.

Description

technical field [0001] The invention belongs to the technical field of harvesting and modulating fresh tobacco leaves of flue-cured tobacco, in particular to a "half leaf" curing method for reducing starch content of flue-cured tobacco, and relates to a fresh tobacco harvesting hanging rod and a matching curing method for reducing the starch content of cured tobacco leaves in a dense curing room . Background technique [0002] Starch generally contains about 25 to 40% in fresh tobacco leaves, and is an important basic carbohydrate in tobacco leaves. The soluble sugar and reducing sugar that are degraded and converted during the baking process, and the acidic products produced by the lysate during smoking are balanced by the tobacco. The alkaline fumes produced during the smoking of alkalis and nitrogenous compounds have a positive effect. Under the condition of C / N balance in cured tobacco leaves, the lower the starch content in tobacco leaves, the better. [0003] It is g...
