Tobacco Industry

Do you know where the best cigars in the world are made? In Cuba, where the natural humidity is high and the tobacco is not dried during processing. The situation is different in Slovakia since we are far away from the sea and during the year the indoor air is more often dry than optimally humidified.

Tobacco leaves, chopped tobacco, and paper are extremely hygroscopic, which means that they give up their moisture very quickly to the surrounding air if it is too dry. A few hours in a dry environment can mean a permanent loss of tobacco quality. Dry air causes tobacco shrinkage, brittleness, tearing, and weight loss. Such tobacco will not hold well in cigarettes and will crumble from them.

In order to keep the balance between air humidity and tobacco, it is recommended to maintain high relative humidity during the individual stages of tobacco processing. This can be, depending on the specific stage, between 60 to 88% RH.

After all stages of processing the tobacco into a raw material ready for the production of cigarettes and cigars, the moistened tobacco is stored in storage tanks. In these spaces, the relative humidity should be 60-70% and the temperature 21-24°C. If the humidity drops below 50% RH the tobacco starts to dry out and an electrostatic charge can build up.

It is very important to maintain the optimal humidity of the cigarette paper too. When the air is too dry, its edges began to dry and tear during the packing process. This results in unnecessary downtime when the torn paper has to be repeatedly replaced.

The optimal relative humidity for the storage of tobacco products is 60% to 75% and the temperature is around 24°C. Cigarettes can lose their moisture and deteriorate in dry air within a few hours. The aroma and quality of stored tobacco products will be preserved in a warehouse, which has ensured the humidification of the space.


Industrial humidification with dry fog will help you set and maintain an optimal level of relative humidity during the entire tobacco processing and storage. Dry fog will help the tobacco to retain its quality.

the industrial system of dry fog humidification 

The Smart Dry Fog Controller uses dry fog spraying for adiabatic cooling. The system uses temperature and humidity sensors that enable it to automatically adjust the humidification to reach the desired values.

  • Dry fog evaporates while still in the air. It doesn’t create condensation on the floor, walls, or products, it only ensures optimally humidified air. Dry fog sprayers are among the most widely used in the tobacco industry.
  • Ceiling installation ensures the even distribution of humidified air throughout the space.
  • Dry fog humidification cools the space by 2 to 4°C and thus helps to create ideal conditions for tobacco processing and storage.
  • Temperature and humidity sensors send data every 5 minutes to the reporting system. You can view the current status and report for any period at any time.
  • If the temperature or humidity changes outside the parameters, you will receive an instant notification.
  • The system is easy to install and has minimal maintenance requirements.
