Tobacco Humidification

misting sa Tobacco Humidification

Misting SA is using environmental control to increase profits, by maintaining product quality and reducing wastage

In order to ensure superior quality tobacco it is essential to retain the appropriate relative humidity during production.  As tobacco is a plant with high moisture content, it loses moisture within a dry environment, you are guaranteed shrinkage, flaking, brittleness, splitting and loss of weight of tobacco. The correct level of humidity can prevent aforementioned problems, with the ideal moisture content being about 15%.

The use of Misting SA’s misting systems during tobacco production takes less water than other methods, it is advised to mist for several times for a shorter period. For efficient production it is essential to maintain the RH between 60-70%, this will guarantee that tobacco, paper and leaves retain moisture at the proper levels.

Recommended RH levels

The different phases during tobacco production require different humidity levels and temperature.

Cigar and cigarette making  55 – 65
Softening     85 – 88
Stemming and stripping 70 – 75
Packing and shipping 65
Filter tobacco casing and conditioning 75
Filter tobacco storage and preparation 70 – 75
Wrapper tobacco storage and conditioning 75
Curing 70 – 75

Advantages of tobacco humidification

  • Ensure optimum product quality
  • Lower energy costs
  • Increase in productivity
  • Saving of labour and maintenance costs
  • Product weight loss is averted
  • Cigarette papers  retain their dimensional values
  • Reduction of static electricity

How does Misting SA control the  environment?

With the use of Misting SA’s  series of speciality  MIST nozzles placed in a line around the perimeter of an area, or by using specially designed MISTING rings, attached to box / oscillating fans,   when connected to a high pressure MISTING system pump, water is forced through the specialty nozzles and quickly atomized to droplets as small as  (5 microns).

Misting systems will produce billions of tiny droplets every second. If these droplets are introduced into an outdoor area, they quickly evaporate. This process of evaporation requires energy to be completed. The energy is taken from the air in the form of heat. The result is a temperature reduction of up to 12 degrees, depending on the ambient temperature and the relative humidity of the air. This method of temperature reduction is the most common use for all MISTING systems.
When misting systems are placed inside an enclosed area (such as a greenhouse), the billions of droplets that are produced will initially provide cooling as the droplets evaporate. However, if the air exchange is limited, the misting system will continue to increase the humidity level within the structure. Humidity levels as high as 90+% are possible. This unique characteristic of all misting systems makes them ideal for both outdoor cooling and humidification.
