Embodiment 1

[0025] A method for collecting and roasting green tobacco in a high-altitude tobacco area, comprising the following steps:

[0026] (1) Harvesting

[0027] When the weather is fine, the tobacco leaves are harvested when they show the characteristics of yellowing and maturity again under the conditions of sunlight and ventilation; when the weather is continuously cloudy and rainy, the tobacco leaves are at risk of being water-dried, so they should be harvested immediately;

[0028] (2) smoke

[0029] When the tobacco leaves are loaded into the kang, the distance between the poles of the kang is 28cm;

[0030] (3) Yellowing and stable temperature section

[0031] After filling the tobacco, heat it immediately to make the dry bulb temperature reach 39°C and keep it at this temperature, while keeping the difference between the dry bulb temperature and the wet bulb temperature at 4°C until the tobacco leaves turn yellow completely;

[0032] During the process of heating to make ...

Embodiment 2

[0040] A method for collecting and roasting green tobacco in a high-altitude tobacco area, comprising the following steps:

[0041] (1) Harvesting

[0042] When the weather is fine, the tobacco leaves are harvested when they show the characteristics of yellowing and maturity again under the conditions of sunlight and ventilation; when the weather is continuously cloudy and rainy, the tobacco leaves are at risk of being water-dried, so they should be harvested immediately;

[0043] (2) smoke

[0044] When the tobacco leaves are loaded into the kang, the distance between the poles of the kang is 25cm;

[0045] (3) Yellowing and stable temperature section

[0046] After filling the tobacco, heat it immediately to make the dry bulb temperature reach 40°C and keep it at this temperature, while keeping the difference between the dry bulb temperature and the wet bulb temperature at 3°C ​​until the tobacco leaves turn yellow completely;

[0047] During the process of heating to mak...

Embodiment 3

[0055] A method for collecting and roasting green tobacco in a high-altitude tobacco area, comprising the following steps:

[0056] (1) Harvesting

[0057] When the weather is fine, the tobacco leaves are harvested when they show the characteristics of yellowing and maturity again under the conditions of sunlight and ventilation; when the weather is continuously cloudy and rainy, the tobacco leaves are at risk of being water-dried, so they should be harvested immediately;

[0058] (2) smoke

[0059] When the tobacco leaves are loaded into the kang, the distance between the poles of the kang is 30cm;

[0060] (3) Yellowing and stable temperature section

[0061] After filling the tobacco, heat it immediately to make the dry bulb temperature reach 40°C and keep it at this temperature, while keeping the difference between the dry bulb temperature and the wet bulb temperature at 3°C ​​until the tobacco leaves turn yellow completely;

Abstract

The invention provides a picking and baking method for reviving tobacco in a high-altitude tobacco area, and solves the technical problems that in the prior art, when the reviving tobacco in the high-altitude tobacco area is baked by using an existing baking method, yellowing and dehydration are difficult, dry leaves are prone to browning during color fixing, and the baked tobacco leaves are poorin grade. The method comprises the following steps: (1) harvesting; (2) carrying out tobacco loading; (3) carrying out yellowing temperature stabilizing; (4) carrying out color fixing; and (5) after the tobacco leaves are dried to 2 / 3 of the leaf drying degree, continuously heating to achieve the dry bulb temperature of 48-50 DEG C, keeping at 48-50 DEG C, stabilizing the wet bulb temperature at 38-40 DEG C until the main veins of the tobacco leaves in the whole heatable brick bed are completely dried, and finishing tobacco leaf baking. According to the picking and baking method for the reviving tobacco in the high-altitude tobacco area, tobacco leaves become yellow and dehydrated easily, browning during color fixing of the dry leaves can be avoided, slice steaming or vinasse slices are avoided, and the grade of the baked tobacco leaves can be improved.

Description

technical field [0001] The invention relates to a method for curing tobacco leaves, in particular to a method for collecting and curing greenish tobacco in high-altitude tobacco areas. Background technique [0002] Turning green tobacco means that the tobacco leaves are affected by rainfall, which makes the mature and yellowed tobacco leaves turn green and tender again. The characteristics of turning green tobacco in high-altitude tobacco areas are: 1. The moisture content in the tobacco leaves increases compared with normal tobacco leaves; 2. The contents change, the chlorophyll content is high, the carbohydrate content such as starch decreases, and the protein increases; thicker, denser tissue structure. [0003] When baking, it is difficult for the tobacco leaves to turn yellow and dehydrate, and the dry leaves are prone to browning when the color is fixed, which is not easy to bake. When the existing baking method is used for baking, the grade of the tobacco leaves is n...
