The problem of tobacco leaf moisture regain has always been of great concern to tobacco farmers, mainly because if the tobacco leaf does not absorb enough moisture, it will become dry and fragile, causing great difficulties in the transportation of tobacco leaves. The tobacco industry knows that tobacco leaves are also graded. To make good quality tobacco leaves, it is very important to maintain the relative humidity of the air. One of the indicators to measure the value of tobacco leaves is the completeness of the tobacco leaves. If the tobacco leaves are not complete enough to sell for a good price, how to solve this problem?

Tobacco leaves are dry and fragile because of insufficient moisture. To keep the tobacco leaves intact, the main thing is to add moisture to the tobacco leaves. Generally speaking, there are two ways to add moisture to tobacco leaves. One is the natural moisture regaining method, and the other is to humidify the air through a tobacco leaf moisture regaining machine to add moisture to the tobacco leaves. The natural moisture regaining method generally opens the doors and windows of the Kang house or warehouse in the evening, and uses the humidity in the natural air to regain the tobacco leaves. However, this method takes a long time and is subject to regional and environmental restrictions.

       Compared with the natural moisture regaining method, many tobacco farmers are directly equipped with tobacco leaf moisture regaining machine. This equipment can shorten the regaining time. Generally, it takes 6-7 hours for natural moisture regaining. This is still 2 hours when the weather is wet. The smoke of a kang can be regained from the left and right, and it is not restricted by the weather environment. Sometimes the tobacco leaves will become dry after being left for a period of time after the moisture regains, and the moisture regainer can be used at any time to ensure that the moisture content of the tobacco leaves does not decrease, so that there will be no fragile tobacco leaves. At the same time, the tobacco leaf moisture regaining machine also has the advantages of convenient operation, good atomization effect, and time and labor saving.
