Tobacco moisture regain machine

*Tobacco leaves are also graded, and the higher the grade, the higher the price. In order to improve quality, every step in the production process must be done just right, let's take the example of buying back tobacco. Freshly baked tobacco leaves have low moisture content, and the leaves are dry and fragile. Proper humidification treatment is necessary, otherwise the quality and yield will be reduced. The humidity should be moderate. If the humidity is not enough and the water absorption is too low, it will cause breakage during smoking, transportation, and grading operations, reduce output value, and cause economic losses. Generally, the effect of moist smoking is better during high temperature and high humidity seasons. However, this natural moisture regain method is greatly affected by the environment and takes a longer time. Therefore, many tobacco farmers use it in order not to affect production efficiencyTobacco moisture regain machine.

The moisture content of tobacco leaves should be appropriate during trading, neither too high nor too low. Low moisture content leads to brittle leaves, which not only increases the proportion of broken smoke during operations such as smoke production, sorting, and grading, but also affects yield and leaf integrity. Increasing the proportion of broken smoke affects the grade. But if the moisture content is too high, it is easy to mold, which further affects the yield and quality. Generally, some measures are taken to increase the humidity of the leaves. When the tobacco leaves are held in the hand and feel slightly dry, they can be released from the oven and used for moist smoking.

When tobacco leaves continue to regain moisture, do not feel dry or make noise when held in hand, and are not easily broken, the leaf veins are prone to breakage, and the leaves become soft but not easily broken. Therefore, tobacco sorting, separation, and tying should be carried out. At this point, the moisture content is 16% to 18%, and the sale meets the national procurement standards. If you don't submit it temporarily, you don't need to classify it and store it in a suitable location. In order to prevent mold growth during storage, the moisture content should be lower, preferably at 15%. This type of leaf feels dry and makes a slight noise when touched by hand. The leaf veins are easily broken and the leaves are more prone to breakage. So, the storage operation should be light and sealed tightly with plastic sheeting after stacking. The moisture content during storage must not exceed 18%. The excessive leaf veins caused by damp smoke are soft and not easily broken, and the leaves are damp and not easily pulled apart. When the leaves stand up, they bend down one after another, sticking together into a cake that cannot be restored to its original state. This type of leaf not only fails to meet the sales standards, but is also prone to mold during storage. Therefore, it is very important to master the standards for moisture regain.

useTobacco moisture regain machineSome things must be noted. For example, moisture regain treatment should be completed as much as possible in the oven to reduce the chance of contact drying, which is both labor-saving and can reduce damage; It is not advisable to take the tobacco leaves out of the oven on rainy days or when the air humidity is high. When it is necessary to take the tobacco leaves out of the oven, they should be covered with plastic film to prevent excessive moisture content. When taking the tobacco leaves out of the oven, they should be handled gently to avoid leaf breakage; Try not to place it directly on the ground after baking. Instead, cover it with plastic film or other materials and store it outdoors for no more than 3 hours. It should be transported indoors for storage and preservation as soon as possible; The moisture content should be controlled between 14% and 15% to achieve "firm but not soft, and not broken when tied".
