This area is probably the most important area for humidity control. Typically, tobacco passes through a compressed air line, first reaching the upper funnel and then into the tobacco equipment. The tobacco is pressed through cigarette-shaped accessories and then wrapped in paper. The amount of tobacco moisture lost during the process depends on the speed of operation of the equipment, the time of exposure to the surrounding air, and the compressed gas used to transport the tobacco from the storage area.
When used for cigarette paper in the form of paper rolls, the humidity must also be balanced with the environment. If the moisture content changes, the size of the edge portion of the corresponding paper roll exposed will also change. This can cause tearing, the machine can't feed the paper correctly, and then stop the product and reload it at a high cost.
The relative humidity of some tobacco producing areas is maintained at 65-68%. The humidity in this area is crucial because the balanced moisture weight of tobacco needs to be maintained between 13-16%. The actual moisture content is related to both products and mixtures. If the humidity drops to around 60%, the moisture in the tobacco begins to drain and dry out. This can have serious consequences, such as when the cigarette is inverted, the tobacco will fall from it. If the humidity exceeds 70%, the excess moisture will make the cigarette paper faint, which is unacceptable to the end customer. Therefore, it is critical to maintain the humidity of the production area at 65% ± 5% for the production line or product quality.
