Problems solved by technology

[0002] At present, there are many types of intensive baking processes and various methods, such as three-stage baking, four-stage baking, multi-step baking, etc. Most of the baking processes adopt stable temperature and humidity, delay yellowing, and color fixing. , the method of drying gluten, in the process of use, it is usually difficult to fix the color of the tobacco leaves that have turned yellow or the color of the tobacco leaves has not turned yellow. Smoke, mildew and rotten smoke, etc., will cause a great loss to the baking of tobacco leaves
The reason for this is that the moisture removal is insufficient during the yellowing stage of the tobacco leaves, and the water content of the tobacco leaves is large, which leads to the outbreak of bacteria, fungi and other germs in the tobacco leaves under low-temperature and high-humidity conditions. Tobacco leaves become hard and yellow, and a "browning reaction" occurs during the color fixing stage, and gray smoke appears; in addition, the temperature and humidity involved in the common baking process are difficult to control. If you are not careful, the temperature will easily rise and fall, resulting in tobacco leaves The problem of drying before yellowing or graying before drying will affect the quality of tobacco leaf curing

Embodiment 1

[0049] 1. Variety of flue-cured tobacco: roast mature tobacco leaves of k326 variety in Yuxi City;

[0050] 2. Overhaul the intensive drying room to ensure that the mechanical equipment is operating normally, the wall is not leaking, and the humidity temperature sensor is working normally; the dense drying room used is an airflow rising dense drying room;

[0051] 3. Only one variety can be baked in one furnace;

[0052] 4. Hanging of temperature and humidity sensors: one humidity sensor is hung on the top floor of the barn, and the other is hung on the bottom floor of the barn. The temperature sensing head is as low as 5cm above the leaf tip.

[0053] 5. Requirements for weaving smoke: the weaving smoke density is 7kg / rod, and the reasonable smoke density is 49kg / m 3 , so that evenly, evenly loaded. The principle of smoke filling is to install one rod less than the smoke density in the low temperature area, and install one more rod in the high temperature area relative to ...

Embodiment 2

[0070] 1. Toast the mature tobacco leaves of krk26 variety in Lijiang City;

[0071] 2. Overhaul the intensive drying room to ensure that the mechanical equipment is operating normally, the wall is not leaking, and the humidity temperature sensor is working normally; the dense drying room used is an airflow descending dense drying room;

[0072] 3. Only one variety can be baked in one furnace;

[0073] 4. Hanging of temperature and humidity sensors: one humidity sensor is hung on the top floor of the barn, and the other is hung on the bottom floor of the barn. The temperature sensing head is as low as 10cm above the leaf tip.

[0074] 5. Requirements for weaving smoke: weaving smoke density 8kg / rod, reasonable smoke density 48kg / m 3 , so that evenly, evenly loaded. Note: The low-temperature area should be packed thinly, and the high-temperature area should be packed densely. The principle of smoke filling is that the low-temperature area should be filled with 2 rods less th...

Embodiment 3

[0089] 1. Roast the mature tobacco leaves of the Honghua Dajinyuan variety in Dali Prefecture;

[0090] 2. Overhaul the intensive drying room to ensure that the mechanical equipment is operating normally, the wall is not leaking, and the humidity temperature sensor is working normally; the dense drying room used is an airflow descending dense drying room;

[0091] 3. Only one variety can be baked in one furnace;

[0092] 4. Hanging of temperature and humidity sensors: one humidity sensor is hung on the top floor of the barn, and the other is hung on the bottom floor of the barn. The temperature sensing head is as low as 8cm above the leaf tip.

[0093] 5. Requirements for weaving smoke: the weaving smoke density is 7.14kg / rod, and the reasonable smoke density is 50kg / m 3 , so that evenly, evenly loaded. Note: The low temperature area is properly packed with thinner, and the high temperature area is properly packed with dense.

[0094] 6. This method is divided into three b...

Abstract

The invention discloses a temperature stabilizing and humidity reducing dense flue-cured tobacco curing method. The dense flue-cured tobacco curing method comprises a temperature stabilizing and humidity reducing yellowing stage, a temperature stabilizing and humidity reducing color fixing stage and a temperature stabilizing and humidity reducing killing-out stage. The method disclosed by the invention can reduce a wet bulb temperature step by step by stabilizing tobacco leaf yellowing, color fixing and killing-out appropriate temperatures, so that a curing target of mutual coordination between tobacco leaf yellowing and water loss, between color fixing and aroma enhancement and between killing-out and aroma maintenance is achieved in a curing process; a yellow flue-cured tobacco rate is improved to a greater extent, and tobacco leaf quality is improved. The method disclosed by the invention has the advantages of simpleness and easiness in operation control.
