Tobacco moisture regain equipment

Tobacco growers know that tobacco leaves are also divided into three, six, and nine grades, and the higher the grade and the better the quality, the higher the price. So how to make * products? Let's learn about it together!

As the saying goes, 'The quality of tobacco leaves depends on planting for three parts and baking for seven parts,' which highlights the importance of tobacco. The freshly picked leaves will have green veins, and the purpose of baking is to remove moisture from the slightly blue-green green and yellow leaves by high-temperature baking, making the leaves yellow. However, baking alone is not enough to change the color. After baking, it will turn into a dark brown color after moisture regain. When processing green leaves, different temperatures and humidification times should be used according to the depth of the green color of the tobacco to achieve color change. In order to maintain the original color and aroma of high-quality tobacco, low-temperature moisture regain is more effective.

There are six main key points in baking: firstly, above 30 ℃ and below 35 ℃, make the tobacco sprout and turn yellow, and solve the problem of bottom green. The observation point is 35 ℃, and when the bottom smoke turns yellow by more than 2 inches, the leaves should appear warm. Secondly, the main temperature point for yellowing is 38 ℃. At the same time as a large amount of yellowing occurs at 38 ℃, the leaves lose water and become soft and collapsed. Thirdly, ensure that all 42 ℃ temperatures are basically yellow. The observation point is that the top platform is mostly yellow with soft collapse. Fourthly, at 48 ℃, it causes the tobacco veins to turn yellow, reaching yellow veins and patches, manifested as small rolls. Fifthly, drying the leaves at 54 ℃ -55 ℃ results in the appearance of large coils, and the gray white color on the back of the leaves disappears. Persist in not drying the leafy meat completely without warming it up. Sixth, dry tobacco gluten at 65 ℃ -68 ℃.

*The product must meet certain humidity requirements, and tobacco leaves are very sensitive to the relative humidity of the air. This characteristic is determined by its own characteristics. Tobacco leaves belong to the category of gelatinous capillary porous substances. Its organization resembles a porous gelatinous sponge body, containing colloidal substances such as pectin, cellulose, protein, as well as crystalline substances such as water-soluble sugars, organic acids, salts, etc. Due to the effects of these substances, tobacco leaves are extremely sensitive to moisture, possessing highly sensitive moisture absorption and release properties, which is particularly evident in the products of *Tobacco moisture regain equipmentHe is one of the helpers in making high-quality tobacco.

Tobacco moisture regain equipmentNot only can it help change the color of tobacco leaves, but it can also achieve the purpose of increasing humidity and weight, meeting the humidity requirements of high-quality products. In addition, it can reduce the breakage rate and minimize crushing, fully realizing the value of tobacco.
