Tobacco and cut tobacco are very hygroscopic, which means that if the air is too dry, they will release moisture into the surrounding environment. Dry air can reduce the characteristics of tobacco, leading to shrinkage, weight loss, brittleness, peeling, splitting, and tearing
This can cause tobacco to fall off the cigarette, cigarette paper to be mistakenly delivered to the machine, and cigar leaves to crack
Maintaining appropriate environmental relative humidity levels can prevent all these problems, ensuring that tobacco, paper, and leaves are maintained at the correct levels, thereby maintaining their quality and ensuring that production can proceed comprehensively.
In terms of humidity control, this may be the most important area. Tobacco is usually transported to the cigarette machine through a pipeline using compressed air and enters the hopper above the manufacturer. Tobacco is forced to pass through cigarette shaped appendages and then wrapped in paper. The amount of water lost by tobacco during this process depends on the speed and exposure time of the machine, as well as the time it takes for compressed air and compressed air to be transported from the storage area
When a cigarette is drawn into a cigarette, the paper packaging the cigarette must also be in balance with the environment. If its moisture content changes, the size of the paper roll will change along its exposed edge. This may lead to tears, machine malfunctions, and expensive downtime for re feeding the drum Most cigarette production areas maintain a relative humidity of 65-68%. The relative humidity of this area is crucial as it can maintain the equilibrium moisture content of tobacco at around 13% to 16% by weight, and the exact moisture content is related to the product and mixture. If the humidity is below about 60% relative humidity, tobacco will begin to lose moisture and dry. This can cause tobacco to fall out of the cigarette when poured out in severe cases. If the humidity exceeds 70%, the addition of moisture can cause paper contamination, which is unacceptable to the end customer. Therefore, maintaining humidity in production areas with a relative humidity of+/-5% is crucial for product production and quality
During the cigarette manufacturing process and after inserting the filter tip, the filter can be laser fired to allow air to be sucked into the small holes in the smoke to control the smoking characteristics of the cigarette. During the laser process, it is necessary to maintain a relative humidity of approximately 55% to prevent blockage of the suction holes in the bracket. Sometimes it is necessary to dehumidify this part of the machine to reach a relative humidity level of 55%. This can be easily achieved by using the industrial dehumidifier installed next to the assembly line and the "dry" air introduced into the laser section Once the cigarette is completed, it is sent to a conveyor system. From here, depending on the type of machine, it will take one of two routes. Older machines without direct connection to the packaging machine deliver cigarettes to the sorting machine and place them in pallets, each with a capacity of approximately 10000 cigarettes. Then move these small cars to another part of the production area and load them into cardboard boxes there. Most modern machines have built-in packaging parts that can be purchased directly from the manufacturer, packaged into over 20 packages, and then packed into 200 cardboard boxes
Connecting to the packaging machine can be a storage/buffering system that can accommodate thousands of cigarettes simultaneously.
. The buffer zone is used to obtain production from the manufacturer. If manufacturing is faster than packaging, on the contrary, if the manufacturer is running slower, a packaging line will be provided. Maintaining a relative humidity of 60-70% inside and around the storage system is also crucial. If the relative humidity is not maintained at the nominal 65%, cigarettes can be stored in a buffer for several hours and exposure to environmental conditions will alter their equilibrium humidity
The industrial dehumidifier can maintain the humidity in the production area during downtime, weekends, meal time and other environments, so that products can remain on the machine without losing humidity, weight and quality
There is also a final area that is sometimes damp. This is where improperly manufactured cigarettes and production waste are broken and tobacco is recycled, and paper and filters are sent to the waste. Any moisture loss will lead to a decrease in tobacco recovery rate, so these areas are usually maintained at a relative humidity of around 65% at 21 º C
As these large amounts of air are constantly introduced, the amount of water that needs to be added may be very high, so great care needs to be taken in the design of humidification systems. People often forget that in winter, when cold and humid air is sucked in and heated from outside, the relative humidity of the air decreases. For example, when winter air enters buildings at 0 º C and 80% relative humidity, heating to 21 º C will result in a relative humidity of around 24%. To maintain the moisture content of tobacco, a relative humidity of 65% is required, and the introduction of air at a relative humidity of 24% will cause the tobacco to lose moisture and prevent proper humidification
