Problems solved by technology

At present, the tobacco farmers in Jiangxi Province are mainly composed of women, children, and the elderly, and the level of baking technology is relatively low. After the fresh tobacco is loaded onto the kang, the "expert mode" in the automatic control equipment is generally used for baking. The quality level is low, and the economic benefits of flue-cured tobacco decline, which seriously affects the enthusiasm of tobacco farmers

Embodiment 1

[0035] Step 1: The fresh tobacco leaves are K326, the part is the lower leaves, and there has been strong rainfall for 3 consecutive days before harvesting, so the quality of the fresh tobacco leaves belongs to "lower leaves - high water content".

[0036] The second step: first classify the tobacco leaves according to the degree of maturity and weave the stems, put the tobacco leaves with slightly higher maturity in the high temperature area, the tobacco leaves with slightly lower maturity in the low temperature area, and the tobacco leaves with normal maturity in the suitable temperature area. After it is full, close the door of the smoke chamber, the auxiliary dehumidification window and the cold air inlet door, and call out the curve of "lower leaves - high water content" from the temperature controller for baking;

[0037]Step 3: After ignition, the fan runs at high speed (1440r / min) for 20 minutes, and then turns to low speed (720r / min). After 8 hours, the dry bulb temper...

Embodiment 2

[0039] Step 1: The fresh tobacco leaves are K326, and the part is the upper leaves. The whole-cured tobacco leaves are over-nutrition due to excessive fertilization, and the quality of fresh tobacco leaves belongs to "upper leaves-over-nutrition";

[0040] The second step: first classify the tobacco leaves according to the degree of maturity and weave the stems, put the tobacco leaves with slightly higher maturity in the high temperature area, the tobacco leaves with slightly lower maturity in the low temperature area, and the tobacco leaves with normal maturity in the suitable temperature area. After it is full, close the door of the smoke chamber, the auxiliary dehumidification window and the cold air inlet door, and call out the curve of "upper leaves-over-nutrition" from the temperature controller for baking;

[0041] Step 3: After ignition, the fan runs at a low speed (720r / min). After 5 hours, the dry bulb temperature rises to 40°C and the wet bulb temperature reaches 39°...

Embodiment 3

[0043] The fresh tobacco leaf is K326, the part is the lower leaf, and the quality of the fresh tobacco leaf belongs to "lower leaf-normal water content"; the tobacco leaves are classified according to the degree of maturity first, and the tobacco leaves with a slightly higher maturity are placed in the high temperature area, and the tobacco leaves with a slightly lower maturity are placed in the high temperature area. Tobacco leaves are placed in the low-temperature area, and tobacco leaves with normal maturity are placed in the temperature-appropriate area. After the tobacco leaves are full, close the door of the tobacco chamber, the auxiliary moisture removal window and the cold air inlet door, and call "lower leaves-normal moisture" from the temperature controller. After ignition, the fan runs at a low speed (720r / min). After 8 hours of ignition, the dry bulb temperature rises to 36°C, and the wet bulb temperature rises to 35°C. At this stage, the tip of the middle shed toba...

Abstract

The invention provides a tobacco leaf classification curing process. The tobacco leaf classification curing process is characterized in that fresh tobacco leaves are classified into 18 classes, including lower leaves-with a high water content, lower leaves-with a normal water content, lower leaves-with a low water content, lower leaves-with root system diseases, lower leaves-with excessive nutrients, lower leaves-with shortage of fertilizer and early aging, middle leaves-with a high water content, middle leaves-with a normal water content, middle leaves-with a low water content, middle leaves-with root system diseases, middle leaves-with excessive nutrients, middle leaves-with shortage of fertilizer and early aging, upper leaves-with a high water content, upper leaves-with a normal water content, upper leaves-with a low water content, upper leaves-with root system diseases, upper leaves-with excessive nutrients and upper leaves-with shortage of fertilizer and early aging. Each class corresponds to one baking temperature system, and all the baking temperature systems are stored in a temperature control instrument to be selected by tobacco growers. The tobacco leaf classification curing process improves the quality of cured tobacco leaves and improves the benefits for the tobacco growers.

Description

technical field [0001] The invention relates to a method for curing tobacco leaves, which belongs to the technical field of flue-cured tobacco. Background technique [0002] Tobacco curing is a complex physiological and biochemical process accompanied by physical changes. Among them, the physical change refers to the continuous vaporization of the water in the tobacco leaves and the discharge of the tissue, so that the tobacco leaves are gradually dried; the physiological and biochemical changes are the most basic and important changes, and they are extremely complicated. It includes fresh tobacco leaf tissue cells in respiratory enzymes, Under the action of hydrolytic enzymes, oxidation and reductases, etc., the whole process of decomposing, transforming and consuming the substances contained in tobacco leaves. The principle of roasting is to study the basic laws of this process, so as to formulate artificial control measures to make the various changes of tobacco leaves d...
