Tobacco is a plant with a high moisture content that, through a natural process, releases moisture into the environment when the surrounding air is too dry. Considering cigarettes, for example, the moisture content may vary by up to 12% in weight when the humidity of the surrounding air varies in the range from 40% to 70% r.H. (at 24 °C).

Dry air causes the leaves to shrink, leading to a loss in weight, an increase in fragility, cracks and tears. This has negative effects on the production process, as it causes the tobacco to come out of the cigarettes, the cigarette paper to get caught in the machinery, and the tobacco leaves used in the production of cigars to break.

The air conditions required in the various tobacco processing phases are typically between 20 and 24 °C, 60 and 70% r.H. For storage, the temperature is usually around 20 °C with 70 to 75% r.H. Different humidity levels and temperatures may be required in specific processing phases or during storage.

• energy saving and low operative costs
• hygienically safe (no re-circulated water)
• user simplicity

Using special stainless steel nozzles, the correct mixture of compressed air and water produces a highly atomised water spray, which evaporates humidifying and cooling the air. The microprocessor controlled cabinet permits precise, and completely automatic, operation of the mc system regulating the flow rate depending on the actual and required humidity level. Atomising nozzles made in AISI 316 stainless steel feature an exclusive self-cleaning mechanism and the controller manages an automatic cleaning cycle which ensures hygienic operation and minimum maintenance. The mc system requires compressed air to operate supplied by an external air compressor (not supplied by CAREL).

Use a high speed spinning disk to atomise the water and transform it into millions of minute droplets.
The droplets, blown by the built-in fan, are introduced directly into the environment, where they evaporate, humidifying and cooling the air. Electrical panels are available for the humiDisk65 to control one or two humidifiers.
These are not an integral part of the humidifier, but rather can be purchased separately.
An electronic board inside the humidifi er, as well as managing the normal operation of the appliance, also runs a tank washing cycle when the unit is started, and a drain cycle at the end of the humidifi cation cycle.
