Dehumidifier for Tobacco Industry

Tobacco leaf baking is a complex physiological and biochemical process that is accompanied by physical changes. The physical change means that the water in the tobacco leaves is continuously vaporized and discharged, so that the tobacco leaves are gradually dried; physiological and biochemical changes are the most basic and important changes, and are extremely complicated, including fresh tobacco leaf tissue cells in the respiratory enzymes, Under the action of hydrolase, oxidase-reductase, etc., the entire process of decomposition, conversion and consumption of tobacco leaf contents. The principle of baking is to study the basic laws of this process, so as to formulate artificial control measures to make the various changes of tobacco leaves develop in the direction that is most conducive to industrial availability, that is, to achieve roasting, roasting, and roasting. The use of air energy tobacco leaf dryers has become the upgrade direction of traditional coal-fired roasters.

First, the main yellowing temperature of tobacco leaves should be controlled at 35-38C, and the temperature difference between dry and wet bulbs should be kept at 2-3 C, so that the tobacco leaves reach 7 - 8 into yellow, and the leaves are soft.

The second is to complete the yellowing temperature control below 40-42C, keep the wet bulb temperature 35-37 C, reach the tobacco leaf is basically full yellow, fully withering collapse, the main vein is soft, ensuring the full conversion of tobacco leaves, forming more aroma Basic substance. Therefore, it is necessary to extend the time appropriately at 41-42C, so that the tobacco leaves reach the yellow-striped blue-striped micro-stripes, the leaves are fully withered and collapsed, and the main veins are soft.

Third, the color fixing stage should be heated according to the quality of tobacco leaves at an appropriate speed, and the appropriate humidity should be mastered to ensure that the tobacco leaves are completely yellowed and smoothly fixed; the dry bulb temperature is 46-48C, the wet bulb temperature is 37-38C, so that the tobacco leaves The stalks turn yellow and reach the small reel of yellow gluten.

Fourth is to keep the wet bulb temperature 38-39C at a dry bulb temperature of 48-52 degrees, and pull it for a long time to reach the large reel of the tobacco leaf, which promotes the formation of more aroma substances. This section is very important for the aroma of tobacco leaves.

Fifth, the maximum temperature of the dry ribs of tobacco leaves should be controlled at 52-68C, and the temperature of wet bulbs should be controlled at 40-43C to increase the color and color of tobacco leaves, and reduce the loss of aroma of tobacco leaves.

Baking is a crucial technical link in the production of flue-cured tobacco. The three-stage baking process of flue-cured tobacco is based on the basic principle of tobacco leaf baking. According to the actual quality characteristics of tobacco leaves and the condition of baking equipment, the essence of domestic traditional baking technology is integrated into the typical simplified baking process framework of foreign countries. Simplify the control of the corresponding indicators of the temperature, humidity, duration and change of tobacco in the baking environment, ensure the change of the appearance of the tobacco leaf baking process and the internal changes, coordinate the internal water dynamics and material transformation, and fully reveal the quality formed and accumulated in the agronomic process. Potential, the tobacco leaves are cooked, roasted yellow, roasted, to achieve the unity of internal quality and appearance quality.
